jQuery事件处理程序性能 [英] jquery event handler performance

问题描述

我有几个这样绑定的事件处理程序:

I have several event handlers that I bind like this:

$('#MyDiv').click(function () {...});
$('#SomeDiv').mouseenter(function () {...});

这些处理程序绑定在document.ready函数中，以后不需要重新绑定，因为HTML始终保持不变.切换到.bind()函数或版本1.7中较新的.on()，性能会有所提高.

These handlers are bound in the document.ready function and don't need to be rebound later because the HTML always stays the same. Will there be any performance gains by switching to the .bind() function or the newer .on() found in version 1.7.

感谢您的建议.

刚刚意识到我在设置中有一个错误.对不起，它们具有相同的性能. http://jsperf.com/jquery-click-vs-bind-vs -on/2
