我注意到有人说要在最新的jQuery中使用"on"，但是有什么区别，我应该使用它吗?

I have noticed some are saying to use "on" in the latest jQuery, but what is the difference and is it true I should use it?

$("#dataTable td").on("click", function(event){
    alert($(this).text());
});

$("#dataTable td").click(function(event){
    alert($(this).text());
});

推荐答案

无.在jQuery源中的此处中查找. .click()函数基本上只是.on('click')的别名，相关代码如下:

None. Look here in the jQuery source. The .click() function is basically just an alias for .on('click'), the relevant code being this:

return arguments.length > 0 ?
    this.on( name, null, data, fn ) :
    this.trigger( name );

尽管.click()更简洁，但我还是建议您使用 .on 一致，因为它始终旨在统一.bind，.live和.click等速记方法引入的事件处理.

Although .click() is more concise I would recommend using .on if you want to be consistent, as it always was intended to unify event handling introduced with .bind, .live and the shorthand methods like .click.
