wizard_oz -> 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....

Lots of folks use JavaScript for this type of checking. Here are just a few examples: http://javascript.internet.com/forms/personal-details-validation.html http://javascript.internet.com/forms/required-fields.html http://javascript.internet.com/forms/ultimate-form-validator.html The site has many more: http://javascript.internet.com/forms/ Or you could check using ASP, after they submit, checking for the empty fields and then redirect them back to the form.

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.
