ajax调用后jQuery点击功能不起作用? [英] jQuery click function doesn't work after ajax call?

问题描述

<div id="LangTable"><a class="deletelanguage">delete</a></div>    

$('.deletelanguage').click(function(){
    alert("success");
});

但是如果我通过 ajax 设置一些 ，$('.deletelanguage').click 不起作用.

例如

but if I set some <a> by ajax, $('.deletelanguage').click doesn't work.

for example

function CreateRow(jdata) { 
    $('#LangTable').append('<a class="deletelanguage">delete</a>');
}

$.ajax({        
    url: "/jobseeker/profile/",
    success: CreateRow
});

现在最后一个 的 $('.deletelanguage').click 不起作用.

jsfiddle 示例:http://jsfiddle.net/suhailvs/wjqjq/

注意:CSS 在这里工作正常.

Note: the CSS works fine here.

我想让这些新添加的 与 jQuery click 一起使用.

I want to make these newly appended <a> working with jQuery click.

推荐答案

问题是 .click 仅适用于页面上已有的元素.如果你要连接未来的元素，你必须使用类似 on 的东西

The problem is that .click only works for elements already on the page. You have to use something like on if you are wiring up future elements

$("#LangTable").on("click",".deletelanguage", function(){
  alert("success");
});
