Using asp.net 3.5, visual studio 2008, javascript, Using IE 6.0
I have an asp.net page with an input tag in a body tag. I want to call a javascript function in an external javascript file. The function should set the value of the input tag to the users computer name when the window loads. I notice that in certain scenarios, it doesn't work. When I put runat="server" on the body tag and set the onload event to call the function in the external javascript file, it gives an error. When I remove the runat=server and put onload="getComputer" directly on the body tag, it works.
Please help me as I thought I understood Javascript and now I'm not so sure.

Hi MrAgile,
Sorry for the late response. II thought that may be the case but the input tag is not a server control. Even when I view source to see the raw html, the id of the input tag remains myComp.
But, I will try it. Where do I put this code in the javascript file? Which part below should I change?
document.getElementById("m
Thanks a lot!

window.onload = getcomputer; - this is the syntax
This code tells the page to run the getcomputer function when the page/ window finishes loading ...
generally we will do this so as to be sure if we are accessing any elements, it would have been loaded and present in the page.
say you need to pass something as a parameter to the getcomputer function you wil need to write it this way
window.onload = function(){ getcomputer(parameter to be passed);};
function(){} is called anonymous functions - without name to be precise.
<body onload="getComputer();"> - why does this work
when specifying the event inside the elements it has to be a function i.e. getcomputer() and not getcomputer
this is similar to the above function but differs in the way the function is triggered.
the onload here is triggered after the body is loaded. there might be a chance a property might not exists inside body, then when you access this element you would get an error.

Hi There,
You need to use something like: <%=mycontrolname.ClientID%>.
