Hi everyone,

I have a form on a web page and I've removed the action part of the form element so that it looks like this:

<form id="catwebformform65782" name="catwebformform65782" method="post" onsubmit="return checkWholeForm65782(this)" enctype="multipart/form-data">

I then use javascript to detect a key press so that the action part is inserted as follows:

$( "#catwebformform65782" ).on( "keypress", function( event ) {
            var action = $("#catwebformform65782").attr("action");
            if ( typeof(action) === "undefined" || action === null || action === "" ) {
                var url = "/FormProcessv2.aspx"
                var params = "?WebFormID=10090&amp;OID={module_oid}&amp;OTYPE={module_otype}&amp;EID={module_eid}&amp;CID={module_cid}";
                $( "#catwebformform65782" ).attr("action",url + params);
            }
});

Open in new window


I test it in the browser by inspecting the form, inserting some text into the first input field, but the action url is not being inserted. I wondered if anyone can help me pinpoint the problem. The full form code is below.

Really appreciate any help.

Thanks in advance.

I'm not sure why you would do that.  ??  The action page is clearly displayed in your javascript so you are not hiding anything.  All I have to do is "View Source" and I have it.

The purpose of it is to deter spam bots. Do you know why it's not working?

I suspect it is because it is too late at the point you are trying to set it.  Try setting the 'action' attribute on page load and see if it will work.

Sorry my javascript is not that good. I'm trying to re-use the code that I was given on a current site that I'm building and it doesn't seem to want to function there. To set the action attribute on page load, would I change this:

        $( "#catwebformform65782" ).on( "keypress", function( event ) {

to this:

        $( "#catwebformform65782" ).on( "pageload", function( event ) {

I don't know why yours doesn't work but I found a page which is probably from another question that works like you want.  It's plain javascript and not jquery.  It's got some extra stuff that you can ignore.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

	function verify() {
		var srrmsg = "";
		
		if (document.reg_form.Full_Name.value=="") {
			srrmsg = srrmsg + " - Full Name:\n";
		}
//Adding another IF statement throws error in FireFox
			if (document.reg_form.email.value=="") {
			srrmsg = srrmsg + " - email:\n";
		}

		//alert if fields are empty and cancel form submit
		if (srrmsg != "") {
			alert("Please Check the Following Fields: \n"+srrmsg);
			return false;
		}
		return true;
	}
</script>

<script type="text/javascript">
<!--
	function frmSubmit() {
		document.reg_form.target = "_blank";
		//document.reg_form.action = "FormMail_Contact.pl"
		document.reg_form.action = "#"
		document.reg_form.submit();
		setTimeout('document.reg_form.target = "_self";window.location = ""',0);

You just pinpointed the probably. I didn't realise it was jQuery so I moved the code after the reference to the jQuery and it now works.

Thanks for your help - much appreciated.
