How to make variables read only on Service portal form widget?

[Neeraj Sharma10]

Requirement : Make variables read only on both native and service portal form if priority field is set to critical on RITM table.

Challenges

1. g_form refer to ritm fields on native view but  only variables on service portal form. i.e g_form.getValue('priority'); returns null on service portal form widget.
   
   Solution : Script Include (Savior) can return any value form any table.
   

   var CatalogUTILS = Class.create();
   CatalogUTILS.prototype = Object.extendsObject(AbstractAjaxProcessor, {
   
   
       isCritical: function() {
           var ritm = this.getParameter('sysparm_ritm');
           var gr = new GlideRecord('sc_req_item');
           gr.get(ritm);
           return (gr.priority.toString() == '1' ? true : false);
   
   
       },
   
       type: 'CatalogUTILS'
   });

   
   
   
2.  g_form.setVariablesReadOnly(true); is not supported on service portal. Reason... It is what it is!
   Solution: Catalog client script
   
   

   function onLoad() {
       if (window === null) {
   	var ritm  = getParameterValue('sys_id');
   	var ga = new GlideAjax('CatalogUTILS');
       ga.addParam('sysparm_name', 'isCritical');
       ga.addParam('sysparm_ritm', ritm);
       ga.getXML(checkCritical);
   
       function checkCritical(response) {
   		var isCritical= response.responseXML.documentElement.getAttribute('answer');
   		if(isCritical == 'true'){
           var allFields = g_form.getFieldNames();
           for (var fieldName in allFields) {
               g_form.setReadOnly(allFields[fieldName], true);
           }
   		}
   	}
       } else {
   		if (g_form.getValue('priority') == '1') {
           g_form.setVariablesReadOnly(true);
   		}
       }
   	
   	function getParameterValue(name) {  
       name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");  
       var regexS = "[\\?&]" + name + "=([^&#]*)";  
       var regex = new RegExp(regexS);  
       var results = regex.exec(top.location);  
       if (results == null) {  
           return "";  
       } else {  
           return unescape(results[1]);  
       }  
   }
   }​

   
   Make sure to Set UI type to ALL and Applies on Requested Items to checked.

the above script works for portal but since we had requirement to make it readonly on both native n portal views, we added one catalog client script simply

and that take care of native view also

function onLoad() {

if (g_form.getValue('priority') == '1') { g_form.setVariablesReadOnly(true); }
}

this is workaround but at least works
