Variable Troubles

[dcbraund]

Hi All,

In the following script I am using a variable named "template" passed through the function as a portion of an element id.

function switchTemplate(template, name) {
if (name == 'Header0') 
{
template.value=document.theform(name).value;
document.all.Selected + template + ID.value='Template Name';
document.all.NewHeaderDiv.style.display='inline';
document.all.SelectedHeaderDiv.style.display='none';
doRenderHTML();
} 
else 
{
template.value=document.theform(name).value;
document.all.NewHeaderDiv.style.display='none';
document.all.SelectedHeaderDiv.style.display='inline';
document.all.SelectedHeaderID.value=document.theform(name).id;
doRenderHTML();
}
} 

The attempt to use the variable is on this line:

document.all.Selected + template + ID.value='Template Name'; 

For example if template = Header, I need the above code to output:

document.all.SelectedHeaderID.value='Template Name'; 

How do I properly use the variable "template" in this situation?

Thanks in advance,
David

Hi David,

var ele, idString = 'Selected' + template + 'ID';
if (document.getElementById) {
  ele = document.getElementById(idString);
}
else if (document.all) {
  ele = document.all[idString]; 
}
ele.value='Template Name';

Mike,

I tried your suggestion but ele is coming up as "null" on the following line:

ele.value='Template Name';

What do you think I am doing wrong?

What browser are you using? Older browsers won't recognize (document.GetElementById)...

I'm Using IE6 on Win XP Pro

I figured it out, the variable i was passing to the function was not in quotes, it works great now!

Thank you all so much for you help
