jQuery event when element is created
提问by rpophessagr
I'd like to trigger an event when an element is created.
我想在创建元素时触发一个事件。
$(document).on('load','#TB_title',function() {
console.log('loaded');
});
Is there an equivalent of this that works?
有没有等效的方法？
I saw some people suggest livequery, but that seems heavy.
我看到有些人建议使用 livequery，但这似乎很重。
Thanks.
谢谢。

I don't think such thing exist directly, but you can handle the DOMSubtreeModifiedevent and wait until you can find element with such ID:
我不认为这样的东西直接存在，但是您可以处理DOMSubtreeModified事件并等待找到具有此类 ID 的元素：
var _elementToFind = "TB_title";
var _elementFound = false;
var _counter = 1;
$(document).bind("DOMSubtreeModified", function(evt) {
if (_elementFound)
return;
if ($("#" + _elementToFind).length > 0) {
alert("element '" + _elementToFind + "' created");
_elementFound = true;
}
});
The downside is that it's not supported by Opera and IE less than 9 - see herethe full details.
缺点是 Opera 和 IE 不支持小于 9 -请参阅此处的完整详细信息。

You can trigger a global custom event:
您可以触发全局自定义事件：
$(document).on('load','#TB_title',function() {
$.event.trigger('nameOfCustomEvent');
});
$('#element').bind('nameOfCustomEvent', function(){
console.log(this);
});
