$('body').on('click', '.anything', function(){})
提问by fancy
$('body').on('click', '.anything', function() {
//code
});
doesn't work for anything right now and I can't figure out why. I'm able to anchor to anything else, say I just toss a #wrapdiv right inside the body. Then I'm able to do
现在对任何事情都不起作用，我不知道为什么。我可以锚定到其他任何东西，比如说我只是#wrap在body. 然后我就可以了
$('#wrap').on('click', '.anything', function() {
//code
});
for any element I want.
对于我想要的任何元素。
Any idea what I could have done to disable this ability on the body element?
知道我可以做些什么来禁用 body 元素的这种能力吗？
Thanks!
谢谢！

You should use $(document). It is a function trigger for any click event in the document. Then inside you can use the jquery on("click","body *",somefunction), where the second argument specifies which specific element to target. In this case every element inside the body.
你应该使用$(document). 它是文档中任何点击事件的函数触发器。然后在里面你可以使用 jquery on("click","body *",somefunction)，其中第二个参数指定要定位的特定元素。在这种情况下，身体内的每个元素。
$(document).on('click','body *',function(){
// $(this) = your current element that clicked.
// additional code
});

If you don't want $('body').on('click'function, just change the function to $('#some_div_id').on('click'. If you want to stretch that div through body (100% height and width), then Hereis a demo.
如果您不需要$('body').on('click'函数，只需将函数更改为$('#some_div_id').on('click'. 如果您想通过主体（100% 高度和宽度）拉伸该 div，那么这是一个演示。
Note: the demo has a 20% padding to body.
注意：演示中有 20% 的填充到正文。

If you want to capture click on everything then do
如果你想捕捉点击一切然后做
$("*").click(function(){
//code here
}
I use this for selector: http://api.jquery.com/all-selector/
我将它用于选择器：http: //api.jquery.com/all-selector/
This is used for handling clicks: http://api.jquery.com/click/
这用于处理点击：http: //api.jquery.com/click/
And then use http://api.jquery.com/event.preventDefault/
然后使用http://api.jquery.com/event.preventDefault/
To stop normal clicking actions.
停止正常的点击动作。
