jQuery 的 .on() 方法结合提交事件 [英] jQuery's .on() method combined with the submit event

问题描述

.on() 有问题.我有多个表单元素(带有 class="remember" 的表单)，我还使用 AJAX 添加了另一个 form.remember .所以，我希望它处理像这样的提交事件:

I've got a problem with .on(). I have multiple form-elements (forms with class="remember"), also I add another one form.remember using AJAX. So, I want it to handle submit event something like:

$('form.remember').on('submit',function(){...}) 

但是用 AJAX 添加的表单不适用它.

but form added with AJAX doesn't work with it.

问题出在哪里?是bug吗?

Where is the problem? Is it a bug?

推荐答案

需要将事件委托给文档层

You need to delegate event to the document level

$(document).on('submit','form.remember',function(){
   // code
});

$('form.remember').on('submit' 与 $('form.remember').submit( 工作相同，但当你使用 $(document).on('submit','form.remember' 那么它也适用于稍后添加的 DOM.

$('form.remember').on('submit' work same as $('form.remember').submit( but when you use $(document).on('submit','form.remember' then it will also work for the DOM added later.
