Multiply drop-down box to text box.

[robert_daughdril]

This should be an easy one.

I have a drop box (0-5) integer.  

Once the user chooses their integer from the dropdown box, the code will use the integer and multiply it by 100 and enter it in another text box. 

Who would you suggest starting my programming training with? 

Thank you for all the assistance.

Read this, and the 2 articles that are linked.

But you don't actually need programming to perform this calculation. It can be done with Simplified Field Notation. Look at the calculate tab on the form field properties dialog.

Hi @robert_daughdril ,

The community forums is a great place to start learning Acrobat Javascript.

There plenty of great developers here that can lead the way and get you on track.

For example, you may run a custom calculation script from the dropdown menu like so:

var f = this.getField("nameOfTextField");

(event.value != 0) ? f.value = event.value/100 : f.value = "";

Or use built-in features as suggested by @Thom Parker 

[robert_daughdril]

var f = this.getField("nameOfTextField"); (event.value != 0) ? f.value =
event.value/100 : f.value = "";

This worked great.

How do I get it to calculate as soon as I choose a number? It always waits
till I enter another choice.

Thank you so much for the help.

Aahh! yes, I forgot to clarify:

• go to the Dropdown Properties,
• and in the Options tab tick the checkbox "Commit selected value immediately".
