Updating Catalog item variable on click in custom table

[MysUser]

Hello, I'd like to set the attribute of Catalog Item variable to ReadOnly by setting "Active" to false on my custom table. It looks like this:

This variable is reference. I tried to use UI Policy on this table with the script:

var variableField = g_form.getControl('u_variable'); 

 var ga = new GlideAjax('CatalogItemUtils');
    ga.addParam('sysparm_name', 'updateVariableReadonly');
    ga.addParam('sysparm_variable', variableField);
    ga.getXMLAnswer(function(response) {
        
    });

And Script Include:

updateVariableReadonly: function(active) {
     
        // Update the field properties based on the checkbox status
        var ac= new GlideRecord('item_option_new');
        ac.addQuery("sys_id",this.getParameter('sysparm_variable'));
		ac.query();
		if(ac.next()){
			ac.setattribute('read_only', 'true');
                        //ac.setAttribute.read_only = true;
	                //ac.read_only = true;
                        ac.update();
        }
    },

It doesn't work 😞

How is it possible to achieve it?

In you UI Policy try:

g_form.setReadOnly('<field_name>', true);

And change your script include to return true/false.

Hi @MysUser ,

Try this script (few changes I did)-

Client Script
var variableSysId = 'your_variable_sys_id'; // Replace 'your_variable_sys_id' with the actual sys_id of your variable
var ga = new GlideAjax('CatalogItemUtils');
ga.addParam('sysparm_name', 'updateVariableReadonly');
ga.addParam('sysparm_variable', variableSysId); // Pass the variable sys_id
ga.getXMLAnswer(function(response) {
// Handle the response if needed
});
Script Include

var CatalogItemUtils = Class.create();
CatalogItemUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {
updateVariableReadonly: function() {
var variableSysId = this.getParameter('sysparm_variable');
var ac = new GlideRecord('your_custom_table'); // Replace 'your_custom_table' with the actual table name
if (ac.get(variableSysId)) {
ac.setValue('read_only', true);
ac.update();
}
}
});
