Using loops to check a form

[simontheak]

Hi there,

I'm trying to write a JavaScript loop to ensure that the half dozen fields of my form are populated before the processing script is called.

I could get JS to check each of the fields individually, but I'd really like to use a loop to streamline my code.

Could anybody help please?

Thanks,

Try Following Function:

<script type="text/javascript">
function DisplayFormValues()
{
var str = '';
var elem = document.getElementById('formName').elements;
for(var i = 0; i < elem.length; i++)
{
str += "<b>Type:</b>" + elem[i].type + "&nbsp&nbsp";
str += "<b>Name:</b>" + elem[i].name + "&nbsp;&nbsp;";
str += "<b>Value:</b><i>" + elem[i].value + "</i>&nbsp;&nbsp;";
str += "<BR>";
}
document.getElementById('lblValues').innerHTML = str;
}
</script>
