onChange script error: TypeError: $$ is not a function function() { [native code] }

[stacybentley]

Using the document https://www.servicenowguru.com/scripting/client-scripts-scripting/removing-form-buttons/ I created a client script to Hide the Submit button.

• Table: Change Request [change_request]
• UI Type: Desktop
• Type: onChange
• Field name: Type

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    if (newValue == 'Routine') {
        //Remove the 'Submit' button
        var items = $$('BUTTON').each(function(item) {
            if (item.innerHTML.indexOf('Submit') > -1) {
                item.hide();
            }
        });
    }

}

When the client script runs I get the error onChange script error: TypeError: $$ is not a function function() { [native code] }

Am I missing something?

Thank you,
Stacy

since a few versions ServiceNow removed default dom access.

Better way is modify the button conditions on when to show it or not.

Hi,

If you want to use this script then you have to make sure that isloate script flag on client script is false. Which will allow you to use DOM manupiluation.

Make sure that your untick the 'isolate script field. If it not available in the form go to form layout of the client script and add to client script form.
