submit problem - 2/11/2008 13:46:30
Hi, I have a problem with checking some fields before click the SUBMIT button. I would like to check the fields and if the feilds are empty I would give a message that say "the feild is empty" and if not, continue to the next page
my code is simple and look like:
<form action="InsertDB.asp" method="get" id="form1" name="form1">
<input id="UserName" name="UserName" class="ghi" >
<INPUT type="submit" value="Submit" id=submit2 name=submit2>
</FORM>
any Idea PLEASE....

You can use the event handler called onsubmit to check the fields.
Below is the code:
<script language="javascript">
function checkfields()
{
var txtUserName = document.getElementById("UserName");
if(txtUserName && txtUserName.value == "")
{
alert("the feild is empty");
return false;
}
}
</script>
<form action="InsertDB.asp" method="get" id="form1" name="form1" onsubmit="return checkfields()">
<input id="UserName" name="UserName" class="ghi" >
<INPUT type="submit" value="Submit" id=submit2 name=submit2 >
</FORM>
This code works well.
I hope this will help you.
