How to access a variable on a catalog task?

[PranavSuj96]

Hello all,

I am writing an onSubmit script which will not allow the user to close the task if a variable from the catalog item that I display on the catalog task (I display it by selecting it in the workflow using the slushbucket). I tried using g_form.getValue('variables.variable_name'). This seems to not work...

Any ideas why? I'll post the script below. Also the onsubmit script is also preventing saving/updating..

Script:

function onSubmit() {

 if(g_form.getActionName('close_task') && g_form.getValue('short_description') == 'Precheck for Server Snapshot' && (g_form.getValue('variables.mc_storage')!='false' || g_form.getValue('variables.mc_storage')!='true')) {
  var val = g_form.getValue('variables.mc_storage');
  alert(val.getDisplayValue());
  return false;
 }
 return true;
}

There is not an out of box business rule for SCTASK, Now I am wondering if you see the variables on your SCTASK? is the variables editor visible on the form? like this?

Yes Just like this!

Okay, if that is the case, we should be able to prevent submission using the business rule. Could you try this?

Advanced: checked

When: Before

On: Update

Script:

(function executeRule(current, previous /*null when async*/) {

	// mc_storage is true or false right?
	if(!current.variables.mc_storage){
		gs.addErrorMessage("MC STORAGE needs to be true!");
		current.setAbortAction(true);
	}

})(current, previous);

On SCTask I see they have the following inactive script:

function onLoad() {
    var variable_map_items = $("variable_map").querySelectorAll("item");
    for (var i=0; i < variable_map_items.length; i++) {
     var variable = variable_map_items[i].getAttribute("qname");
     g_form.setReadOnly("variables."+ variable, true);
    }
  
}

Does this help at all?

That is how they set the variables to read only in the past but there is a new way of doing this now using g_form.setVariablesReadOnly(true);

You could try that script you posted to get the value of the variables but  note that it is considered DOM manipulation and is not best practice. I would much rather use the business rule way instead
