It’s hard to believe that it’s been seven years since I wrote a post showing how you can use client scripts to manipulate the appearance of form UI action buttons. This solution has been used in countless ServiceNow instances to help add more clarity to form buttons and processes in the system. A few months ago, I decided to try and see if I could expand on this client script method a bit to add even more button flexibility with the addition of an option to include an icon along with the button text. Fortunately, with the addition of a new icon set in recent ServiceNow releases, this has become pretty simple to do…all while leveraging a consistent, nice-looking icon set.

Available icons

You’ve undoubtedly seen them in various parts of the system, but you may not have realized until now that there are over 250 icons available to choose from in ServiceNow! You can use these icons in various ways (client scripts, UI pages, UI macros, CMS and Service Portal), including with UI action buttons as I show here. All you have to do to show an icon is to add a class attribute with a name matching the icon you want to add.
ServiceNow had previously published a style guide that you could reference to view all of the icons (and corresponding names to reference them by). For the time being, you can access the icons in your instance by navigating to

The following script can be used in any standard form client script. The key is the ‘transformButton’ function at the bottom. This could be included as a global UI script in your instance so that you don’t need to include it in every single client script. Once that’s in place (whether in a global UI script or in the client script itself) you can just call ‘transformButton’ with the appropriate parameters to change the button however you want. The parameters used are as follows…

  1. UI action name (Mandatory)
  2. Button background color (Optional)
  3. Button text color (Optional)
  4. Button icon name (Optional)
function onLoad() {
//Change the color of the 'Approve' button to green
transformButton('approve', '#77FF77', 'white', 'icon-success-circle');
//Change the color of the 'Reject' button to red
transformButton('reject', '#FF0022', 'white', 'icon-error-circle');
//Change the color of the 'Info' button to blue
transformButton('info_button', '#31708f', 'white', 'icon-info');
//Change the color of the 'Warning' button to yellow
transformButton('warning_button', '#f0ad4e', 'white', 'icon-warning-circle');

function transformButton(buttonID, buttonBackgroundColor, buttonTextColor, buttonIconName) {
//Find the button(s) by ID and change the background color
$$('button[id=' + buttonID + ']').each(function(elmt) { = buttonBackgroundColor;
if(buttonTextColor){ = buttonTextColor;
//Add some spacing between the icon and button label
elmt.innerHTML = ' ' + elmt.innerHTML;
