I am validating the dates in below function. If the validation fails, then the form should not get submitted. I tried returning false in form onsubmit but it still gets submitted. However, Validation is working fine and getting the alert that I put in the function. Any help to stop submitting the form if validation fails.
<script>
function dateCheck()
{
start = document.getElementById('name3').value;
end = document.getElementById('name4').value;
compare(start, end);
document.getElementById('name4').focus();
}
function compare(sDate, eDate)
{
function parseDate(input) {
var parts = input.match(/(d+)/g);
return new Date(parts[2], parts[0]-1, parts[1]); // months are 0-based
}
var parse_sDate = parseDate(sDate);
var parse_eDate = parseDate(eDate);
parse_sDate.setFullYear(parse_sDate.getFullYear() + 1);
if(parse_eDate >= parse_sDate)
{
alert("End date should not be greater than one year from start date");
return false;
}
return true;
}
</script>
</head>
<body>
<form onsubmit="return dateCheck()">
<table>
<tr>
<td><input type="text" name="soname3" id="name3" size="15" readonly="readonly">
<img src="../Image/cal.gif" id="" style="cursor: pointer;" onclick="javascript:NewCssCal('name3','MMddyyyy','dropdown',false,'12')" /></td>
<td><input type="text" name="soname4" id="name4" size="15" readonly="readonly">

</tr>
</table>
<input type="submit" value="Submit">
</form>
