I have a couple of Divs in my page with CSS class="hello" Further I use Ajax to fetch a few more Divs with a CSS class="hello" I have a piece of code which is called on Click event of the Divs as follows:

推荐答案
你应该使用 。对 给处理程序绑定到已经present绑定的执行过程中，另一个元素喜欢说＆LT;身体GT; ，或文件，并将它检测到孩子的事件。但理想情况下，你应该将其绑定到加载的内容的最近的共同的父。
you should use .on to bind the handler to another element that is already present during the execution of the binding, like say the <body>, or the document and have it detect the children events. but ideally, you should bind it to the nearest common parent of the content loaded.
//bind to the body a "click" handler for elements that have class names of "hello"
$('body').on('click','.hello',function(){
alert("Hello Clicked");
})
