find the type of html controls in javascript

How to find the control type in javasccript?. Say if i have an ASP.NET LinkButton a开发者_运维问答nd i wanna find control type from the javascript. How can i do that. I tried using typeof(), but it giving me an object back. and i tried

var control = document.getElementById(Id);//Id is the ClientId of the Linkbutton
alert(control.type);//this is empty.

You can't find the controltype as in ASP.NET in javascript I think. There is the attribute tagName that may help you:

control.tagName returns the HTML tagname. If you really want the ASP control name, you can try to put the controlname in for example the class attribute.

you can't get control type directly by javascript. you can try to use some serverside code to determine control class name:

var cType = '<%= Type.GetType(yourControlServerName).ToString() %>';
alert(cType);

LinkButton is a server side type of control, but in the client side (javascript) there is not a LinkButton but the HTML tags rendered by that control which probably include tags.

So, in the javascript it makes not sense to talk about LinkButtons.

Probably there is a better solution for what you are trying to accomplish.
