Rapid transition of images on the line. How does it work?

E
esther last edited by

When I'm looking at the photos on the line, they're looking, you know, moment (i mean, I threw the next one, and now it's open, no delays). The browser clearly uploaded the new page plus changed the address.
At first, I thought ajax was just going down a little bit, and they're leaving, but no. The address is changing, the page is downloaded. How does this happen so fast?
I looked into the code, there's little I understand. Anyway, I saw ajax.post. Okay, ajax, but the page's loaded, the address's changing. Ajax can't do that. I don't understand.
Who knows, please explain.

1. "Momentally" is what you think... Rather, it's a pre-emptive (upstream) download of images.
2. Loading goes AJAX
3. There's no turning on pages-- it's History API or anchor, depending on the browser.

Inside the cycle for variable cycle key not used. It's a so-called code smell, usually this is wrong.By the way, in your source, the body of the cycle is written correctly.

The problem appears to be in the wrong pattern of regular expression. Rewrite by using indexOf, it's easier and it works necessary.

You're pretty close, all you have to do is return. false which shows a help dialogue avoiding the closure of the page immediately, is at this point where you can send data to some APIs, as this should be a quick process I recommend using navigator.sendBeacon instead of what Angular provides to send data, this because the advantage that it has sendBeacon is that it sends a small amount of information much lighter than a normal HTTP call, considering that the Body of what can be sent in sendBeacon It's kind of FormDataso the code would be as follows:import { Component, HostListener } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.scss'] }) export class AppComponent { @HostListener('window:beforeunload') onUnload() { const data = new FormData(); data.append('name', 'abc'); data.append('location', 'world'); navigator.sendBeacon('http://www.mysitioweb.com/api/v1/endpoint', data); return false; } } You can lastly not customize the message that comes out in the confirmation dialog, this has been adopated by most browsers to maintain consistent and safe behavior

Not really. https://ru.wikipedia.org/wiki/Base64 ♪Only the Latin alphabet symbols in the upper and lower register - symbols (A-Z, a-z), figures (0-9), and symbols " plus " and " / " with the symbol "= " as a special souffix code.Give symbols ,♪ : and ;♪ Yes, and if you use it instead decode64 Method strict_decode64You'll get it. ArgumentError♪It's actually that. https://en.wikipedia.org/wiki/Data_URI_scheme containing not only the data themselves, but also their type (content type) and the method of coding (which may not be base64).There is already a sufficiently elegant adapter for a standard library, https://github.com/dball/data_uri which allows this URI to be broken into clean-up components:require "data_uri" uri = URI(ваша_строка) File.write('sample.jpg', uri.data) But in this particular case, there is something very simple, equivalent to:base64 = ваша_строка.split(',').last # в base64 не бывает запятых, так что это безопасно data = Base64.strict_decode64(base64) File.write('sample.jpg', data)

For the treatment of images there are several libraries available. O https://packagist.org/packages/liip/imagine-bundle has as a general purpose to facilitate the task of serving images. In your case, for the creation of images, I believe that it will not serve.I did a quick search and found the https://packagist.org/packages/phpixie/image that seemed very simple and functional. The library https://packagist.org/packages/gregwar/image It also looks like a great option.I didn't use any of them, so my evaluation is limited to the API and the documentation available.If you want to search more libraries, the website https://packagist.org has several options.

I'm assuming you have any idea how browsers work. What you're trying to do is manipulate chrome data, not a document. Javascript in your 'document' property is accessing the DOM tree. But none of this has to do with it, you want to delete your search history. de chrome but javascript does not have access to such data.If you want to check it from another perspective... https://stackoverflow.com/questions/2190808/how-to-clear-browsers-ie-firefox-opera-chrome-history-using-javascript-or-j

Windows QtGlobal::qrand() Just causing a standard function. rand() of cstdlib♪ It seems that its specific implementation uses some systemic time, so the value returned does not change if the time has not changed from the point of view of the function. The problem can be solved by using the own pseudent cell generator, for example, https://ru.wikipedia.org/wiki/%D0%9B%D0%B8%D0%BD%D0%B5%D0%B9%D0%BD%D1%8B%D0%B9_%D0%BA%D0%BE%D0%BD%D0%B3%D1%80%D1%83%D1%8D%D0%BD%D1%82%D0%BD%D1%8B%D0%B9_%D0%BC%D0%B5%D1%82%D0%BE%D0%B4 ♪

I'm not sure, but at first glance I think your mistake is that you overwrite the value of me.plataformas = element in every iteration. The ideal thing would be for you to treat it as an array and insert the values like this:me.plataformas.push(element) Then render it in the template like this: <div class="m-3" v-for="plataforma in plataformas" :key="plataforma.id"> {{plataforma.key}} </div>

The problem is that the variable $linha_descricao does not exist, the right is $linha, because the results of your query are here: $linha = $resultado->fetch(PDO::FETCH_ASSOC);$dadoReceitaDescricao[$i] = array( 'numero_de_linhas' => $numero_de_linhas, 'decricao' => $linha['descricao'], // <-- aqui 'complemento' => $linha['complemento'], // <-- aqui 'valor_unitario' => $linha['valor_unitario'], // <-- aqui 'todos_meses' => $linha['todos_meses'], // <-- aqui 'numero_de_meses' => $linha['numero_de_meses'] // <-- aqui ); Besides, you have another mistake. In this line:$resultado = $database->conexao->query($sql); The right is:$resultado = $database->query($sql); The error Uncaught TypeError: Cannot read property 'numero_de_linhas' of null happens in the JS, explaining that this variable came null, because there were these previous errors in its connection with the bank.
