Re: Possible to check for empty input boxes when names generated dynamically?

Hi, I'm trying to find a way to validate input text boxes where I
don't know the names until the page is rendered. I've got 2 validate
functions that fire with the onsubmit button of a "mini" form within
the html document.

(substitute your form name in here)


var l = document.formname.elements.length;
for (var i=0; i<l; i++)
{
var e = document.formname.elements[i];
if (e.type=="text")
{
if (isBlank(e))
{
alert("Blank!");
return false;
}
}
}
return true;

function isBlank(strObject)
{
/* Returns false if the field has any non-space characters, true if
not.
You must pass in an input (text) object (not the value) */
var index;
var myChar;

if (! strObject)
{
return true;
}
else
{
var str = strObject.value;
}

for (index = 0; index < str.length; index ++)
{
myChar = str.charAt(index);
if (myChar != " ")
{
return false;
}
}
return true;
}

Kaeli, I'm trying to modify your code (without success!) to check
document.all instead of a specific form. I now just need to see if any
input type="text" elements exist, not if they're empty. I won't bore
you with what I've tried cause it don't work!

Thanks again for your help.

Kathy
