ASP.net Client-side Validation

A couple of days ago, I faced a situation whereby I needed to add some form validation to an aspx page.

I had options of either JavaScript or ASP.net client side validation. JavaScript seemed like an easier solution…
<h5>Client-side JavaScript for form validation</h5>

[code lang=”js”]
<script language="javascript">
<!–
Function CheckForm(form)
{
for(var intCtr = 0; intCtr <= (form.elements.length – 5); ++intCtr)
{
var temp = form.elements[intCtr];
if(temp.type == "text" && temp.value == "")
{
alert("Please Enter All Information!");
temp.focus();
return false;
}
}
return true;
}
//–>
</script>
[/code]
