jQuery .now()不是唯一的 [英] jQuery .now() not unique

问题描述

我有一个 jsfiddle .

obj = {};
obj[0] = 'hej';
obj[1] = 'hopp';

$.each( obj, function( key, value ) {
    console.log($.now());
});

$.now()在控制台中是相同的数字.

$.now() is the same number in the console.

如何生成唯一编号?

推荐答案

您可以有一个针对每个对象递增的计数器.然后，您可以将此计数器添加到$ .now()以确保其唯一性:

You could have a counter which increments for each object. You could then add this counter to $.now() to make sure it's unique:

obj = {};
obj[0] = 'hej';
obj[1] = 'hopp';
counter=1;

$.each( obj, function( key, value ) {
    console.log($.now() + counter);
    counter+=1;
});
