CSS3 could be used in key features of the site?

Amritpal last edited by

As far as I know, SSS3 appeared relatively recently, and consistent, old browser versions don't support it. Please indicate whether the key features of the SSS3 site are allowed to be used, and if the old browser doesn't work, the page looks not like a page, but as a bunch of scattered knobs, it's impossible to use it. It is therefore very interesting to know how many people now use old browsers, and how critical the use of CSS3... Any recommendations?

Transformed by all modern browsers, including IE9+, currently benefiting about 1.6% of the users of Runet. With the other properties, the situation is similar. So you decide whether to use these properties on your website or not.

If you'd like to use the static data in template, you need to add data to the context of the current copy of the component (template receives and interpolates data from context this)Vue performs the transformation process getter/setter during initialization of the copy, so the properties should be present data An object so Vue can transform it and make it real.Given that, you can add the statistic in the cock. createdbecause, when the Hook is caused, Vue has already completed the reactive data phase (observation phase) and cannot detect the addition or disposal of properties (to make them reactive).const staticData = { HEADER_TITLE: "Список заказа", HEADER_REMOVE: "Очистить все", FOOTER_TITLE: "Итого:", CURRENCY_UNIT: "руб.", UNIT: "ед.", PRISE_FOR_UNIT: "Цена, за 1 ед.", ON_REQUEST_TEXT: "по запросу", EMPTY_CART_TITLE: "Ваша корзина пуста", EMPTY_CART_TEXT: "Выберите в каталоге интересующий товар и добавьте в корзину", EMPTY_CART_LINK_TEXT: "Перейти в каталог", } new Vue({ el: "#app", created() { // добавление статических данных this.staticData = staticData; } })<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script> <div id="app"> <div v-for="(text,key) in staticData" :key="key"> {{key}}: <b>{{ text }}</b> </div> </div>In more detail - https://vuejs.org/v2/guide/reactivity.html#For-Objects

Try to directly call the "panel-body" class responsible for the images in your CSS, for example:.panel-body { text-align:center; background-color:red; } After improving your CSS code, do not forget to replace:<div class="panel-body" style="background-color:red; text-align:center"> By:<div class="panel-body"> This should already solve your problem.

How to use the value of a variable to set a key to an object?

In JavaScript itself, an object can be created in two ways:// Forma 1 let obj1 = { name: "Fulano", age: 37 }; // Forma 2 let obj2 = { "name": "Fulano", "age": 37 }; That is, the key can be set with quotation marks, or without quotation marks.In view of this, when you pass as argument the object:{ filter : { '$regex' : input, '$options' : 'i' } } You are passing an object that has the key filter, therefore, this form of key definition is accepted. However, as the input is being passed as a value, and not as a key, JavaScript considers that you are using a variable.Therefore, a way for you to use the value of a variable as the key to an object would be to use JSON.parse to convert one string in an object, like this:let jsonObject = JSON.parse({ "${filter}" : { "$regex" : "${input}", "$options" : "i" } }); const clients = await Client.find(jsonObject); Another way (even simpler) — and already that based on the definitions of ES6 — would be to use the definition of a key through the value returned by an expression, thus:const clients = await Client.find({ [filter]: { "$regex": input, "$options": "i" } }); That is, there in [filter], a key with the variable value will be set filter.And when it is said "expression", one can even think of concatenation expressions of strings, for example:{ [filter]: { ['$' + 'regex']: input, "$options": "i" } } That is, the resulting key ['$' + 'regex'] it will be "$regex".This form may become more interesting because it ends up leaving the code, in a way more "clean", besides not requiring it to use an additional functionality that is now "unnecessary".However, note that to use this functionality on the side of the front-end, it may become necessary to implement some tools, such as https://babeljs.io/ , so that there is compatibility with older browsers (i.e. browsers that do not "support" the ES6).I hope I helped!

When I tried to do that on one project, I had to do it on jquery, so... http://masonry.desandro.com/ To the library. There are examples, it's quite simple. Under your task, I think it's appropriate (after the library itself and jquery)$('#container').masonry({ itemSelector: '.box' }); where #container - it's the identifier of the block, and .box - class for the blocks themselves. Here. http://masonry.desandro.com/demos/basic-single-column.html That's what's gonna happen.

Synthaxis:тег[имя_атрибута=значение] I mean, it doesn't have to be a class. For example, the element:<div my_tag="test"></div> css: div[my_tag=test]Sovereignty !important - if you have more than one of the values of some sss properties for the element, the default priority will be the last. If one of them is identified !importantit will be a priority, regardless of the order.

When using one or another depends on what you want.If you use for example:<div> <button onclick="clicaMe(event);">Clica-me!</button> </div> and JavaScriptvar el = document.querySelector('div'); function clicaMe(e) { console.log('inline this', this); // vai dar window console.log('inline e.target', e.target); // vai dar button } el.onclick = function (e) { console.log('onclick this', this); // vai dar el, ou seja "div" console.log('onclick e.target', e.target); // vai dar button } el.addEventListener('click', function (e) { console.log('event handler this', this); // vai dar el, ou seja "div" console.log('event handler e.target', e.target); // vai dar button }); jsFiddle: http://jsfiddle.net/2fqp1se6/ Notice when you run a function via onclick inline in HTML the scope of this It'll be window. In other cases this is the very element that received the eventhandler or onclick. The e.target is always the concrete element that received the click, descending from the element to which the event handler was tied if the click was fired on it. There is another parameter to take into account: bubbling (or event spread). Notice this example:var el = document.querySelector('div'); var btn = document.querySelector('button'); el.addEventListener('click', function (e) { console.log('div this', this); // vai dar el, ou seja "div" console.log('div e.target', e.target); // vai dar button }); btn.addEventListener('click', function (e) { console.log('button this', this); // vai dar button console.log('button e.target', e.target); // vai dar button }); jsFiddle: http://jsfiddle.net/2fqp1se6/2/ In this case both event handlers are fired as once the button gets the click it propagates the event to the parent elements, and firing your eventhandlers on that path. See also the eventhandler de btn Fire first!.This can be useful to distinguish between this and e.target when you want to know in detail which element clicked.

What expressive gain do we have when using the new module system?Here, as far as I could read and feel the taste (I couldn't help a big sip, just a vine at the tip of the tongue) of Jigsaw, are two main advantages:you can create classes that will not expose and use in any package of your moduleoptimization of class search by classpathThe first part even I felt when trying to put a legacy code to run with Java 12: Oracle has now decided to actually hide her intimate implementations.I don't know if you remember, but you know the packages sun.java.*? Well, they were internal packages that should be consumed only by JRE/JDK of Sun/Oracle. In thesis, no program made to run in Java should depend on these packages. What was it possible to do with Jigsaw? Remove them from path Then what happened to a legacy library that I had to access sun.misc.BASE64Encoder? ♪ ClassNotFoundException and the system stopped.Honestly, did I find it bad? No, as incredible as it sounds, I didn't find it bad. Just curious. As the code to this library was lost in space/time (and it is a depreciated artifact), it only served as another push to abandon it.Now, how you get an improved performance in the search for classpath?Let's go back to the class that I had no more access, sun.misc.Base64Encoder. When you are in a module, the first search will be for classes of that module. So in the case of the module java.base (Let's pretend, okay? I don't know what the real module would be), at some point it was necessary to access the class sun.misc.Base64Encoder. The processing was within the module java.base, then the first thing he does is to inquire inside the module who is sun.misc.Base64Encoder and he finds that class, public.Now we're in my implementation. Suppose it is properly ported to Java 9 and tries to access sun.misc.Base64Encoder. The first thing that ClassLoader will try to do it will be to see, within the module in which I sit, if you have any class with that signature. The answer will be no. So at that time, I also go through all the other modules of the classpath that I declare to use (or inherited via transitive) and see if you have someone who provides the package sun.misc, without entering them deeply for further inspections. Perhaps one or the other library in Java 8- offers some resistance because, by default, they behave like modules with all available packages.Have you seen how search time is reduced using modules?In terms of complexity, how easy is your applicability in large projects that are already running in Java 8 for example?Can you modulate your program well? If so, the first step will be to make a module-info.java with the following information:what are the modules I depend on? requiresfor each required module, should I leave available to third parties that matter from my module or not? transitivewhich packages will programmatically expose so that it is grafted as part of classpath for other modules? exportswhich classes would like to be accessible via reflection, even if it is not "available" to access directly by ClassLoader´?opensThis step of the opens is the most delicate when using a framework that relies heavily on reflections (such as Spring, Hibernate, MyBatis etc).Setting all this correctly, and making proper separation of modules, the rest should flow naturally. I particularly see more Jigsaw application for libraries, but I have not seen reasons to prevent an application from being separated into modules.Now these definitions are not trivial to do. Perhaps a reengineering of the original code to hide the implementation by moving it to another package is necessary.During library upgrade, back and a half came across conflicts between versions and dependencies. In this modularization scenario, does this problem become more common?One advantage that this scheme provides is being able to have several classes with the same name. The only requirement for this is that they are not exported packages. A very well-balled library can make proper use of this, but most of it is missing with target for Java 8.Another point is that this does not exime dependency management by Maven or Gradle (or what you use for this purpose). So I don't see how the use of modules would decrease these upgrade problems (with possible class exceptions with the same signature in two distinct modules).References: https://www.baeldung.com/project-jigsaw-java-modularity https://openjdk.java.net/projects/jigsaw/

Problem of style CSS♪ You've signed a form identifier in the sector. It's a bad practice, if it's changed, you're getting stylished. Add the form to "wrapper" div with class and describe it.HTML:<div class='form-feedback'> <?php require_once(get_template_directory().'/form.php'); ?> </div> CSS:.modal-content { padding: 30px 50px; } .form-feedback .wpcf7-response-output { display: none !important; } .form-feedback .wpcf7-not-valid-tip { display: none !important; } .form-feedback .form-label { width: 100%; font-weight: bold; margin-top: 15px; } .form-feedback input { margin-top: 5px; border: 1px solid #cdcdcd; -webkit-border-radius: 2px; border-radius: 2px; width: 100%; padding: 15px; font-weight: bold; } .form-feedback textarea { font-weight: bold; margin-top: 5px; border: 1px solid #cdcdcd; -webkit-border-radius: 2px; border-radius: 2px; width: 100%; resize: none; height: 100px; padding: 15px; } .form-feedback .wpcf7-submit { background-color: #e82b2b; background: #e82b2b; color: white; } .form-feedback .wpcf7-submit.checked { -webkit-transition: 0s !important; -o-transition: 0s !important; transition: 0s !important; background: url("/wp-content/uploads/2019/01/25.gif") no-repeat center center; -webkit-background-size: 35px 35px; background-size: 35px; background-color: #e82b2b; } .form-feedback .wpcf7-submit.ok { -webkit-transition: 0.5s !important; -o-transition: 0.5s !important; transition: 0.5s !important; background: #08da19 !important; } .form-feedback .ajax-loader { display: none; } .form-feedback .error-message { color: #e40f24; margin-left: 5px; } .form-feedback .policy-checkbox { margin-top: 10px; text-align: center; } .form-feedback .policy-checkbox .checkbox-container { display: inline-block; } .form-feedback .policy-checkbox p { display: inline-block; margin: 0; margin-left: 5px; } .form-feedback .policy-checkbox .fake-checkbox { cursor: pointer; border: 1px solid #efefef; width: 30px; height: 30px; display: -webkit-box; display: -webkit-flex; display: -ms-flexbox; display: flex; -webkit-box-pack: center; -webkit-justify-content: center; -ms-flex-pack: center; justify-content: center; -webkit-box-align: center; -webkit-align-items: center; -ms-flex-align: center; align-items: center; } .form-feedback .policy-checkbox .fake-checkbox i { visibility: hidden; } .form-feedback .policy-checkbox .fake-checkbox.active i { visibility: visible; } .form-feedback .policy-checkbox span { display: inline-block; } .form-feedback .policy-checkbox a { color: #e40f24; border-bottom: 1px solid transparent; } .form-feedback .policy-checkbox a:hover { border-bottom: 1px solid #e40f24; }

To matplotlib you need to pass a list of coordinates X and another list with the corresponding coordinates Y.A simple way can be to generate several X values in a loop, for each one to evaluate your function, and to store in separate lists the Xs and Y that you are generating. So:def funcion(x): # Despejamos la y en la ecuación 20x+30y=30 return (30-20*x)/30 X = [] Y = [] for x in range(20): y = funcion(x) X.append(x) Y.append(y) Once you have both lists you would use this matplotlib:import matplotlib.pyplot as plt plt.plot(X, Y) plt.show() For the following figure: Another possibility most frequently used is to make use of the numpy library, which can vectorially operate with numbers lists. In this case X would be a vector with several abciss values, and when you pass that vector to the previously written function, what returns you is another vector with the corresponding values of the orders. You thus avoid the loop, having a single call to the function that calculates "once" all the necessary values thanks to the vector magic of numpy:import numpy as np X = np.arange(20) Y = funcion(X) The way to generate the plot would be the same as before, as matplotlib admits indistinctly python lists or numpy vectors.

https://www.postgresql.org/docs/current/static/datatype-oid.html It's a primary key. The question is whether you should leave it as PK or use another one that makes it no longer used as PK.It is not simple to fasten it, but you can obviously do it. It has some conditions that indicate its use, but not all. There are situations that have no problem using it, it may be that you just need a primary key for a technical issue, i.e. your application doesn't care about it.My opinion is https://www.postgresql.org/message-id/m13FdJf-000AXVC%40druid.net , avoid using it, and if use make sure you understand all the implications of its use. I prefer to have full control over the primary key. I never used it. oid. They have some disadvantages and few advantages, nothing serious, but I think it's enough for me. I'd rather use a serial anyway.No referential integrity,transferring values externally can be a huge complication, it is not GUID,is out of the standard, even specific PostgreSQL tools ignore it,you have no control over it,the question already shows that the use of * doesn't include her.If you need a composite key then you have to use it, oid It's no alternative to this.
