Validate multiple fields

[seaport]

I just learned to write Javascript. the following is some code used to validate 9 fields in a form. However, the code does not work. I think the problem is where I try to refer to all textboxes in the form - theform.elements["txtex" + i]. What should I do?

****
function DataValidation(theForm)
{
var i
// alert("All expense field must be entered."
for (i=1; i<10; i=i+1)
{
if (theform.elements[&quot;txtex&quot; + i]==&quot;&quot
{
alert(&quot;All expense field must be entered.&quot;
return (false);
}
}
return (true);
}

****
I tried to call this function from the following code.

****
<FORM METHOD=&quot;Post&quot; ACTION=&quot;view.ASP&quot; name=&quot;frmBudget&quot; onsubmit=&quot;return DataValidation(this)&quot;>
****


Thanks in advance.

In your for loop, the line contain
if (theform.elements[&quot;txtex&quot; + i] ==&quot;&quot

should put a checking statement, it can replace by

if (theform.elements.type == &quot;text&quot{
if (theform.elements.value ==&quot;&quot{
...
}
}

I already know all these txtex1, txtex2, ..., txtex9 are text.

Maybe I need to rephrase my question. Can I retrieve the value of a text in a form like:

theform.elements[&quot;txtex1&quot;].value
