2.difference behaviour b/w platform and in portal

[nameisnani]

Hi Team , 

There is a difference behavior between Portal and Platform ends. 

We have catalog called Lost or Stolen Device. Based on device type, a Short description is populating .

For example, if I choose device type is 'Laptop' >> In short description field, it is populating like this, i.e [ Lost/Stolen Laptop Report] [By requestor for name ] 

For this, i have written client script.

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    var reqFor = g_form.getDisplayValue('requested_for');
    var newvall = g_form.getDisplayValue('device_type'); //replace with the backend name of device type field


    //g_form.setValue('short_description_1', newvall +' '+ ": Device Type " + ' ' + " Reported By " + reqFor);
    g_form.setValue('short_description_1', "Lost/Stolen " + newvall + ' ' + " Reported By " + reqFor);





}

Now , the problem I am facing is that this is working fine in portal, but when we are checking from the platform , it is not working .

If you could see in the below screenshot , in the short description field, the requestor for name is not populating .

can anyone please help me with this issue , where i have to update in my scirpt? 

Please help what was the mistake , and where should i update ?

I think for core UI you need to use getDisplayBox() instead of getDisplayValue()

@Brad Warman  Thanks for your quick reply. Could you please provide me with the updated script?

@Brad Warman 

// function onChange(control, oldValue, newValue, isLoading) {

//     if (isLoading || newValue == '') {
//         return;
//     }

//     var reqFor = '';
//     var newvall = '';

//     if (window == null) {
//         // Service Portal UI
//         reqFor = g_form.getDisplayValue('requested_for');
//         newvall = g_form.getDisplayValue('device_type');
//     } else {
//         // Core UI
//         reqFor = g_form.getDisplayBox('requested_for').value;
//         newvall = g_form.getDisplayBox('device_type').value;
//     }

//     g_form.setValue('short_description_1', "Lost/Stolen " + newvall + ' ' + " Reported By " + reqFor);

// }

 I have update like this , still not working . could you please what was the mistake i did here .

The issue you're facing could be due to differences in how the platform and portal handle client scripts, particularly in how g_form.getDisplayValue() behaves. Here are a few steps to troubleshoot and fix the issue:

1. Check the Field Names:

• Ensure that the field names used in the script (requested_for and device_type) are correct and consistent across both the platform and the portal.

2. Use g_form.getValue() Instead of g_form.getDisplayValue() for Platform:

• The getDisplayValue() method returns the display value of the field, which might work differently between the portal and platform. Instead, try using g_form.getValue() for the requested_for field, and then manually fetch the display value using a GlideAjax call if needed:
  function onChange(control, oldValue, newValue, isLoading) { if (isLoading || newValue == '') { return; } var reqForSysId = g_form.getValue('requested_for'); var deviceType = g_form.getValue('device_type'); // Fetch the display value for 'requested_for' using GlideAjax if needed var ga = new GlideAjax('UserDetails'); // Custom Script Include needed ga.addParam('sys_id', reqForSysId); ga.getXMLAnswer(function(response){ var reqFor = response.responseText; g_form.setValue('short_description_1', "Lost/Stolen " + deviceType + ' Reported By ' + reqFor); }); }

3. Custom Script Include for GlideAjax:

• Create a Script Include named UserDetails to fetch the display value of the requested_for field:
  var UserDetails = Class.create(); UserDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, { getDisplayValue: function() { var sysId = this.getParameter('sys_id'); var userGR = new GlideRecord('sys_user'); if (userGR.get(sysId)) { return userGR.getDisplayValue(); } return ''; } });
