Dropdown selection based on fields?

On the right pane: tools/javascript

Create a name for your script (use the name of the function you are about to create) and click "add"

then it shows like this:

you created a document level function

you call that function whenever you need the code to "run" simply with this line:

manProdColor()

You can call the function from the validate or the calculate event, from another function, etc.  So instead of having to copy the same script to a bunch of fields, you create a function and call that function from those fields.  If you need to change something inside the function, you make the change only once instead of having to go into each individual fields.

here is a simple example:

function hello(){

     app.alert("hello world")

}

hello()  //Calling the function hello() from a button will launch the alert.

If you have a tousand buttons of such and want to change the string to "hello universe", you better wish you used a function instead of hardcoding the same thing 1000x.

You can also pass values as arguments to a function and return a value from a function:

function doubleMe(x){

     return x * 2

}

var a = 10

var b = doubleMe(a)  //b = 20
