jQuery:element.click(func)或element.attr('onclick'，'func()')效率更高吗? [英] jQuery: is element.click(func) or element.attr('onclick','func()') more efficient?

问题描述

我正在通过将元素克隆到列表中来填充列表.然后，我更改属性以使每个项目都唯一.他们需要在点击时调用一个函数，所以我想知道使用new_element.click(func);或new_element.attr('onlick','func();');

I'm populating a list by cloning elements into it. Then I change attrs to make each item unique. They need to call a function on click, so I'm wondering if it's more efficient to use new_element.click(func); or new_element.attr('onlick','func();');

推荐答案

new_element.attr('onclick','func();');

是:

• 效率低下(不必要地从字符串创建新的内联函数，除了调用func并失去this引用外，什么都不做)；

• inefficient (needlessly creating a new inline function from a string, that does nothing except call func and lose the this reference);

加重放置任何复杂的代码，因为所有代码都必须转义为JS字符串；

aggravating to put any complex code in, since it all has to be JS string escaped;

由于setAttribute中的错误而在IE中损坏.

broken in IE, due to bugs in setAttribute.

避免. click()/bind('click')在这里是有原因的.

Avoid. click()/bind('click') is there for a reason.
