How to clear field value when "Leave sit" dialog box is "Cancel"

[Salah2]

Hi all,

Is possible to clear field value when when "Leave sit" dialog box is "Cancel" 

Variable name: deadline_submission

type: yes/no

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') {
        return;
    }

    if (newValue === "No") {
        var redirectURL = '/core?id=sc_cat_item&sys_id='; 

        top.window.location.href = redirectURL;
    }
}

Thank you for your help.

Hi,
Try this 

// Client Script: Clear Field Value on Dialog Cancel

function onLoad() {
// Assume that we are using a GlideModal to create the dialog box
var dialog = new GlideModal('Leave sit');
dialog.setTitle('Leave site?');
dialog.setBody('<p>Are you sure you want to leave the site?</p>');

// Add Cancel button
dialog.addCancelButton('Cancel', function() {
// Clear the field value when cancel is clicked
g_form.setValue('your_field_name', '');
dialog.destroy();
});

// Add other buttons/actions as needed
dialog.addOKButton('OK', function() {
// Handle OK action
dialog.destroy();
});

// Show the dialog
dialog.render();
}
