Javascript Form Validation

[ainoy31]

Hello-

 

I am having an issue with validating my form.  Here is my form input fields:

 

<form name="usage" action="usage_detail.php" method="post" target="_blank">
<input type="text" class="DW100" id="f_date_c" name="start_date" readonly="1" / value="" />
<input type="text" class="DW100" name="end_date" id="f_date_c2" readonly="1" / value="">
<div class="ButtonContainer Inline"> <a class="Button Small" href="#" id="FormSubmit" onClick="validateDates(this.form);"><span>View</span></a></div>
</form>

 

Here is the javascript that I am using but it does not validate and continues to the next page.

 

<script language="javascript" type="text/javascript">
<!--
function validateDates()
{
if(document.usage.start_date.value == '' || document.usage.end_date.value == '')
{
ok = false;
}
else
{
ok = true;
}
if(ok = true)
{
document.usage.submit();
}
else
{
alert("The start and the end dates need to be entered.");
}
}
//-->
</script>

 

Much appreciation.  AM

Try change the 'href' for the button from 'href=#' to HREF='javascript:void(0);'
