Changing background colour of combobox in pdf

[R345832923f42]

Hi guys,

Need some help with Javascript in pdf form. 

I have the following script for a "combobox31" (with options Yes & No)to change background fill to yellow if the No option is selected. The script is working fine in Nitro pro but not in Microsoft edge or Chrome.

I want to make the document compatible with widely available pdf programs like Acrobat, Nitro, Edge and Chrome. Is the following script not supported by Edge and chrome? Is it possible to get  a similar highlighting script which will have better compatibility with more pdf softwares?

var v = getField("ComboBox31").valueAsString;
if (v=="Yes") {event.target.fillColor = color.yellow;}
else {event.target.fillColor = color.transparent;}

Thanks,
