Drop down list value dependant on value in another drop down list

[Former Community Member]

Hi

I am not familiar with Java Script so if anyone can advise me on this I would be grateful.  I am using ADobe Livecycle V8.0.

I have two drop down lists - DDL1 and DDL2.

The choices in DDL1 are "High, Medium, Low, None"

The choices in DDL2 are "Positive, Negative, None"

If "None" is selected in DDL1 I want DDL2 to display "None". 

If any of the other values are selected in DDL1, then I don't want anything autofilled in DDL2.

Hope this makes sense!

Thank you.

This should do the trick:

in the "change" event of DropDownList1, put this:

if (xfa.event.newText == "None"){

DropDownList2.selectedIndex = 3; // at pos. 3, you should have "None"

                                                       // otherwise change here at your convenience

}

else {

DropDownList2.selectedIndex = 0; // here first element empty/default

                                                        // maybe you prefer the last one

}

Note that generally dropdown boxes have the first or last element empty/default; this way, when you script the "else" part, you can easily reset DropDownList2.

Hi mrfale67,

Just wanted to say thank for your help. After I spent a while figuring out the logic of your code it worked perfectly - so thank you for that, I appreciate it.
