如何查看您是否两次单击同一元素? jQuery的 [英] How to see if you're clicking the same element twice? Jquery

问题描述

如何检测用户是否单击了相同的div?

How can you detect if the user is clicking the same div?

我尝试了这个没有成功:

I've tried this with no success:

    _oldthis = null;

    var _this = $(this);

    if(_oldthis == _this) {
        alert('You clicked this last');
    }

    _oldthis = _this;

推荐答案

您不能比较jQuery对象，但是可以比较它们包含的DOM对象.试试这个:

You can't compare jQuery objects, but you can compare the DOM objects they contain. Try this:

var previousTarget=null;
$("a").click(function() {
    if(this===previousTarget) {
        alert("You've clicked this element twice.");
    }
    previousTarget=this;
    return false;
});
