abort onSubmit client script not working in Service Portal

[michelek87]

I have a client script where I need to check if they have included an attachment and if not, pop up an alert and abort submission of form.

The alert pops up but the form still submits.

I have reviewed several community threads including the one about the callback function which I also tried.

This is the latest version of my script:

function onSubmit() {
   var attGA2 = new GlideAjax("LaptopAttachmentHelper");
   attGA2.addParam('sysparm_name', "checkAttachment");
   attGA2.addParam('sysparm_userName', g_user.userName);
   attGA2.getXML(attResponse2);
}
function attResponse2(response){
   var answer = response.responseXML.documentElement.getAttribute("answer");
   if (answer == "none"){
   alert("Please attach DS-0132 before submitting form.");
   g_form.submitted=false;
   return false;
   }
}

line 16 doesn't make any difference.

I am getting the alert but as soon as I click OK on the alert, the form is submitted in the portal.

Thanks,

Michele

We had a similar requirement at our client. Return false statement is necessary but insufficient to to   prevent form submission in onSubmit() function. Use synchronous glideAjax to achieve this. I provided code below that worked for me. Hope this helps.

Client Script:

-----------------------------------------------------------------------------

function onSubmit() {  

  var attGA2 = new GlideAjax("LaptopAttachmentHelper");  

  attGA2.addParam('sysparm_name', "checkAttachment");  

  attGA2.addParam('sysparm_userName', g_user.userName);  

  attGA2.getXMLWait();  

  var answer = attGA2.getAnswer();  

  if (answer == "none"){    

  alert("Please attach DS-0132 before submitting form.");  

  //g_form.submitted=false;   //not needed

  return false;        

}

}

------------------------------------------------------------------------------

Code Changes in Script Include:

Use return answer; instead of msg.setAttribute() function to return answer from script include to client script.
