Name of object field as variable

Marcee

Have a good day. Specify how js can assign a variable name to the object field.

var typeLogin = 'phone' //значением может также быть email, login, id 
var myLogin = '+7 000 00 00 00' //значением может быть a@b.com, vasya, 1234
$.ajax({

type: 'post',

url: 'login.py',

data: {

'login': true,

typeLogin: myLogin, // вот здесь именем поля должно быть значения переменной typeLogin а не ее имя

}

});

esther

If you use ES6, you can use it.

var typeLogin = 'phone' //значением может также быть email, login, id 
var myLogin = '+7 000 00 00 00' //значением может быть a@b.com, vasya, 1234
$.ajax({

type: 'post',

url: 'login.py',

data: {

'login': true,

[typeLogin]: myLogin,

}

});

The truth is the support of the browsers can be chrome.
Yuzabel or Bakend with NodeJS.

The values of an object are "referencias", so you do not freeze "variable" in itself, but yes the object and by setating it into another variable in fact you are not copying, but yes "referencing", for example:let x = { "foo": { "bar": 1 } }; let y = { "baz": x.foo }; y.baz.bar = 400; console.log(x);See how to change y.baz.bar and display x (and not y) was displayed 400, which was previously sealed in y, this because you do not "clone" the values, but in fact it is referenced, some other languages have similar behavior.Then Object.freeze will freeze the reference if you want to copy the values from one object to another (clonar) use the Object.assign, so:var a = { ... }; var b = Object.assign({}, a); Here's a test: let a = { "teste" : [1,2,3] } // Quero 'b' freezado const b = Object.assign({}, a); Object.freeze(b); a.teste = [4,5,6]; console.log("a:", a); console.log("b:", b);

Here I show you a proposal using fixed elements and only CSS Key classes here arebutton-radio--main The main buttonbutton-radio--hidden The auxiliary buttons that will be hiddenGiven the structure I propose to you the elements within button__container, the main button should be located from the last to the inside of this container, otherwise it works well without any additional Javascript/jQuery help..button__container { position: fixed; bottom: 30px; right: 40px; display: -webkit-box; display: -ms-flexbox; display: flex; -webkit-box-pack: center; -ms-flex-pack: center; justify-content: center; -webkit-box-align: center; -ms-flex-align: center; align-items: center; -webkit-box-orient: vertical; -webkit-box-direction: normal; -ms-flex-flow: column nowrap; flex-flow: column nowrap; } .button-radio { width: 70px; height: 70px; cursor: pointer; border-radius: 50%; margin: 5px 0; -webkit-box-shadow: 0 0 10px 3px rgba(0, 0, 0, 0.3); box-shadow: 0 0 10px 3px rgba(0, 0, 0, 0.3); display: -webkit-box; display: -ms-flexbox; display: flex; -webkit-box-pack: center; -ms-flex-pack: center; justify-content: center; -webkit-box-align: center; -ms-flex-align: center; align-items: center; } .button-radio--red { background: #ff1f1f; } .button-radio--blue { background: #03a1fc; } .button-radio--yellow { background: #ffd21f; } .button-radio--hidden { width: 10px; height: 10px; opacity: 0; -webkit-transition: 0.3s ease-in-out; transition: 0.3s ease-in-out; } .button__container:hover > .button-radio--hidden { width: 50px; height: 50px; opacity: 1; }<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <link rel="stylesheet" href="test.css"> <title>Document</title> </head> <body> <div class="button__container"> <div class="button-radio button-radio--hidden button-radio--yellow">A</div> <div class="button-radio button-radio--hidden button-radio--blue">B</div> <div class="button-radio button-radio--main button-radio--red">C</div> </div> </body> </html>

You can also use https://developer.mozilla.org/es/docs/Web/JavaScript/Referencia/Sentencias/for...in :var myVar = { typeA: '501', typeB: '502' }; for (var key in myVar) { console.log(key); console.log(myVar[key]); }EDIT:I had to edit the answer as there were changes in the https://es.stackoverflow.com/revisions/40453/1 :var myVar = { test: { typeA: '501', typeB : '502' } }; for (var key1 in myVar) { console.log(key1); for (var key2 in myVar[key1]) { console.log(key2); console.log(myVar[key1][key2]); } }

You can remove it from the anonymous function, how you have it usually confuse the browser with the parameters and produce an error or warning, and change it var a let That's right.It worked this way.dotsl = document.getElementsByClassName("dots") for (let j = 0; j < dotsl.length; j++) { dotsl[j].addEventListener('click', function(event) { console.log('hola mundo! ' + j ); }); }<div class="dots">a</div> <div class="dots">b</div> <div class="dots">c</div> <div class="dots">d</div>

What is standardization? Do you want to know the standard dev度 factor (e.g. contribution of each description variable) instead of the re帰 expression (direct relationship between the purpose variable and the description variable)?If you do not want to leave a constant clause, you should also standardize the purpose variable.

Transfer value not from id, but immediately to:<button onclick="loadWin("x")">Кнопка1</button> <button onclick="loadWin("y")">Кнопка2</button> <button onclick="loadWin("z")">Кнопка3</button> Total function loadWin(t) Accept the weight that has come, then:xmlhttp.open("GET","window"+t+".php",true); The next code is no longer necessary:var x = document.getElementById('x'); var y = document.getElementById('y'); var z = document.getElementById('z');

There you go.#define trace(x) cout << #x "=" << x; Here. #x Open "a"♪Between #x and "=" You can't. <<because the construction literature on the side is automatically merged into one.

I think that https://xaviesteve.com/354/acentos-y-enes-aparecen-mal-a%C2%B1-en-php-con-mysql-utf-8-iso-8859-1/ can solve your problem.Costing When creating the MySQL database, make sure that the string and other fields are in utf8_spanish_ci and the co-placing of the tables in utf_unicode_ci (later in Operations  Collation of phpMyAdmin can be changed) Content type HTML Put in that of all HTML files:<meta http-equiv="Content-type" content="text/html; charset=utf-8"/> Content type PHP And in the purely PHP (which show XML, AJAX calls, APIs...) put the code:header("Content-Type: text/html;charset=utf-8"); Set names By creating the PHP connection with MySQL, send this query right after the connection:mysqli_query("SET NAMES 'utf8'"); For MySQLi writes:`$acentos = $db->query("SET NAMES 'utf8'"); ` Convert encoded to UTF-8 Convert everything that is encoded from latin1 to UTF-8 (thank you Guillermo)SELECT convert(cast(convert(content using latin1) as binary) using utf8) AS content Apache Remove the Apache DefaultCharset or modifine it htmlentities As the last and desperate option, remove all htmlentities(); and replace it with another parser to ‘sanitize’ the data.

The safest thing is that both objects were declared locally and not globally, otherwise it would not have allowed you.I mean you have two functions public void funcion1() { int numero = 0; } public void funcion2() { int numero = 1; } Both functions have the same name, but when they are local they are destroyed by leaving the method so they only have impact within the same method, you could also do public void funcion1() { int numero = 0; funcion2(); } public void funcion2() { int numero = 1; } And there would be no problem, the problem would come when you declare a global function and a local with the same name or two local functions with the same name or two global functions with the same name. The language will not know which variable with that name to point, some languages like java if it allows you to create local variable and global variable pointing with a this. to the global variable and if it is put without the 'this' is pointing to the local variable.private int numero; public void funcion1() { int numero = 0; this.numero = numero //la variable global será igual a la local } But no language will allow you to create two local variables or two global variables with the same name.Remember that most language is caseSensitive, meaning that they differentiate between capital and lowercases, it is not the same Numero that numero and NUMERO

I don't quite understand the question. The method shall render the tree of the elements with One The original element. If ElementProducts is used in some other component, the table, for example, you have to do something wrong. You need ElementProducts (when it is better known as ElementProduct, of course) to return one element and the bulkhead of this.props.items to be implemented in this table.
