how to make a field read only using ui action

[SK41]

Hi,

I  have a requirement where i need to create the "assign to me" button on interaction form, when some user clicks that button , then the interaction should get assign to him & the "assigned to" field should become read only.

The interaction  is getting assigned correctly, but when i try to add read only code then it is not working.

Below is the code:

show insert is true

show update is true

form button is true

condition: current.active==true &&gs.getUser().isMemberOf(current.assignment_group) 

script :

current.assigned_to = gs.getUserID();

current.update();
action.setRedirectURL(current);

how to ensure that the interaction gets assigned when button is clicked & the assigned to field become read only?

Kindly, help!

Thanks!

Hi @SK41 
You can try this method

//Client check box true
function assignTicket() {

    var ga = new GlideAjax('validateUserGroup');
    ga.addParam('sysparm_name', 'validateGroup');
    ga.addParam('sysparm_grp', g_form.getValue('assignment_group'));
    ga.getXMLAnswer(getResponse);

   function getResponse(answer) {
        if (answer == 'false' || answer==false) {
            alert('User is not part of assignment group');
            return false;
        } else {
            g_form.setValue('assigned_to', g_user.userID);
            g_form.setReadOnly('assigned_to', true);
            gsftSubmit(null, g_form.getFormElement(), 'assign_ticket');
        }
    }
}

//script include
var validateUserGroup = Class.create();
validateUserGroup.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    validateGroup: function() {
        var group = this.getParameter('sysparm_grp');
	gs.addInfoMessage(group);
        if (gs.getUser().isMemberOf(group)) {
            return true;
        } else {
            return false;
        }
    },
    type: 'validateUserGroup'
});
