jQuery选择动态创建的html元素 [英] jQuery select dynamically created html element
问题描述
我的这个问题有很多问题与几乎相似的标题,但你知道我没有找到答案。
我的简单问题是:
我有按钮,当我点击它时,javascript创建模态窗口
There are a lot of asked questions with almost similar titles with this question of mine, but you know I didn't find an answer.
My simple question is:
I have button, when I click on it, javascript creates modal window
<div class="aui-dialog">
html here...
<button id="closeButton">Close</button>
</div>
在< body>
标记之后。
我可以使用jQuery live 绑定关闭按钮的click事件没有问题:
just after <body>
tag.
I can bind click event of close button with no problem using jQuery live:
$("#closeButton").live("click", function() {
alert("asdf"); // it calls
$("body").find(".aui-dialog").remove();
});
我的问题是,我无法选择动态创建的模态窗口div by它的类名。这样我就可以调用jQuery .remove()方法来进行关闭操作。现在我知道了,我必须以另一种方式处理动态元素。
什么方式?
My problem is, I cannot select that dynamically created modal window div by its classname. So that I could call jQuery .remove() method to make close action. Now I know, I must deal with dynamic elements in another way.
What way?
编辑:
我认为提到这一点很重要:
我不自己创建模态窗口,我使用 liferay 门户网站。它内置了javascript框架 AUI ( YUI )创建该模态窗口。我可以在其视图中创建其中的关闭按钮。
I think it's important to mention this:
I dont' create the modal window myself, I use liferay portal. It has built-in javascript framework AUI(YUI) that creates that modal window. I can just create that close button inside it in its view.
编辑2:
模态窗口div类属性值为: aui-component aui-panel aui-dialog aui-widget-located
推荐答案
在创建模态窗口时创建引用:
var modalWindow = $('<div class="aui-dialog">html here... <button id="closeButton">Close</button></div>');
// later...
modalWindow.remove();
要编辑:
当按钮位于模态窗口内时,通过jQuery的 parent
获取窗口:
Get the window via jQuery's parent
when the button is inside the modal window:
$('#closeButton').on('click',function() {
$(this).parent().remove();
return false;
});
