jQuery .on与.live [英] Jquery .on versus .live

问题描述

我知道 .live()现在已被弃用，但我似乎无法对其进行更改并保留其功能.

I know that .live() is now deprecated but I cannot seem to change it and keep the functionality.

我只是对jQuery中的.on()函数有一个简单的问题.我目前正在.live() 此处

I just have a quick question about the .on() function in jQuery. I'm currently using .live() here

像这样:

$('table tr th').live("click", function() {
});

但是，当我尝试用.on()替换.live()时，它不再按预期工作.

But, when I try and replace .live() with .on() it no longer works as it's supposed to.

我尝试放入

$('table tr th').on("click", function() {
});

以及

$('table tr').live("click", "th", function() {
});

和

$('table tr').delegate("th", "click", function() {
});

但无济于事.

这是为什么，我应该采取什么步骤使其正常工作?

Why is this and what steps can I take to make it work properly?
