jQuery: Find the element with a particular custom attribute
提问by Chro
I just want to find the element with a particular value for a custom attribute.
我只想找到具有自定义属性特定值的元素。
E.g. I want to find a the divwhich has the attribute data-divNumber="6".
例如，我想找到div具有属性的 the data-divNumber="6"。
var number = 6;
var myDiv = $('[data-divNumber = number]');
I tried using http://api.jquery.com/attribute-equals-selector/but what I've done doesn't work.
我尝试使用http://api.jquery.com/attribute-equals-selector/但我所做的不起作用。
There is precisely one element with that particular value for the attribute.
恰好有一个元素具有该属性的特定值。

var number = 6;
var myDiv = $('div[data-divNumber="' + number + '"]');

You need to do some string addition to get the number into your selector and the value needs to be quoted.
您需要进行一些字符串添加才能将数字放入选择器中，并且需要引用该值。
var number = 6;
var myDiv = $('[data-divNumber="' + number + '"]');
What you're trying to produce after the string addition is this result:
添加字符串后您尝试生成的结果是：
$('[data-divNumber="6"]');

I think what you need is:
我认为你需要的是：
var number = 6;
var myDiv = $('[data-divNumber="'+number+'"]');

With ES6 you can use string interpolation:
使用 ES6，您可以使用字符串插值：
let number = 6;
let myDiv = $(`div[data-divNumber="${number}"]`);
