Hi @srikriti ,

OldValue Would not help here, as it store the value of the field which Is at the time of loading of the form.

Can you exactly tell, what are you trying to fetch, is it the temporary last selection made in the field(Not saved/submitted) or something else?

Hi @Rahul Talreja 

yes the temporary last selection made in the field(Not saved/submitted) value

because 

on catalog form i want to use removed value
some dependency on old value is there

Hi @srikriti 

Got it,

You can create a variable previousValue and everytime, save a last value in that variable.

Refer the script below:

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

var previousValue;
if (g_scratchpad.previousValue == undefined){
previousValue = oldValue;
}
else{
previousValue = g_scratchpad.previousValue;
}

g_scratchpad.previousValue = newValue;
}

Hope this might solve your problem!
