Client Script OnChange - Clear field if another one changes

[DesiraeSaysanav]

I would like to create an OnChange Client Script for the Incident form.

When the location changes I need the Configuration Item to be cleared out, this has to work before a save/update is done.

Can someone help me write this as I am not good with scripting. TIA!

How do you have your client script set up? It might help to include a screenshot of the client script so we can see the settings for when to run.

This is what is is currently at

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


//check to see if the value has truly changed
if(oldValue != newValue){
//clear the value of field below
g_form.clearValue('cmdb_ci');
}

}

Thank you, that worked but now once I select a new location and a new CI when I save it clears the CI out again. If i change a second time it keeps it. So I'm having to double save to keep the changes when I select a new location. Any suggestions?

That sounds odd, the script should only run when you change Location, if you've kept the same settings and just updated the script
