传递myControl.ClientID-引用或不引用 [英] Passing myControl.ClientID - to quote or not to quote

问题描述

因此，我经常在后面的代码中做的一件事是设置javascript事件以避免内联代码.

So one thing I often do in the codebehind is setup the javascript events to avoid in-line code.

myButton.Attributes.Add("onclick", string.Format("fnDoSomething(this, '{0}', '{1}');", myList.CliendId, myStatus.CliendId));

非常标准，没有什么令人兴奋的.但是有一天我忘记了引号:

Very standard, nothing exciting. But one day I forgot the quotes:

myButton.Attributes.Add("onclick", string.Format("fnDoSomething(this, {0}, {1});", myList.CliendId, myStatus.CliendId));

令我惊讶的是，我实际上已经传递了myList和myStatus对象本身……而不是ID.

这看起来很酷，无需执行document.getElementById.但是我担心这不能在所有浏览器上或所有情况下都起作用.

任何人都可以明确地说这是否是不好的做法吗?

To my surprise in the script I had actually passed the myList and myStatus objects themselves.... not the IDs.

This seemed pretty cool, no need to do a document.getElementById. But I was worried this wouldn''t work on all browsers or in all circumstances.

Can anyone say difinitively if this is bad practice?

推荐答案

这里没有什么奇怪的.如果使用单引号，则Javascript会将其作为字符串接受.因此，您必须使用document.getElementById来获取实际的ID.而如果您不使用单引号，则Javascript将直接将其作为对象.因此，您不想再使用document.getElementById.

Nothing is surprise here. If you use single quotes, Javascript accept that as a string. So, you have to use document.getElementById to get the actual id. Whereas, if you are not using single quotes, Javascript will directly take this as a object. So, you don''t want to use document.getElementById again.
