Javascript to make a drop down filed choose default values

[Bossom5C48]

I have 4 dropdown fields C1, F1, F2, F3 , the very first field i.e C1 I intend to make as the the controlling field, such that when I choose say :

if string value  not = to "A" in C1 then F1 becomes readonly and also reset to its default values

if string value not= "B" in C1 then F2 becomes readonly and also reset to its default values

if string value not= "C" in C1 then F3 becomes readonly and also reset to its default values

The basic code to do it (as the custom Validation script of C1) is this:

if (event.value!="A") {this.getField("F1").readonly = true; this.resetForm(["F1"]);}

else {this.getField("F1").readonly = false;}

You can duplicate and adjust this block of code for the other fields.
