Set Style action does not work in the On Change event



Set Style action does not work in the On Change event. The action works for the Focus event.

Error Messages

Not Applicable

Steps to Reproduce

1. In a text input field, perform the following, 
- Add an Action Set.
- Add a Change event.
- Add a Set Style action.
- Set Style Source to Inline Style
- Set Inline Style: background-color: yellow; (it does not work with any other Style).
2. Run the case and apply a change to the text input field. The background color does not change on exiting the field.

Root Cause

SetStyle action configuration is valid to configure on hover or focus events as the applied styles will be removed on Focus out or Blur. If the SetStyle action is configured on click, it is not possible to roll back the applied style. Hence, it is recommended to use the hover or focus event.


Perform the following local-change:
  1. To highlight the fields if they changed, enter the below code in the UserWorkForm:

    function changeBGColour(color, event){ 
      var name =; 
      document.getElementsByName(name)[0].style.backgroundColor = color; 

  2. On the control, add the Run script action.
  3. Enter the function name as BGColour.
  4. Pass the parameters as in the below image.

Note: Run Script action must be the final action in the sequence of the actions configured.
