Javascript return Value based on selection in Combobox

Hi all,

based on the selection that the user has to make in a combo box I want a value to be written into another field, I tried the following code but it does not work:

----

var Land = this.getField("combo1").value;

 

if (Land == "Afghanistan") {
event.value = 20;
}
if (Land == "Ägypten"){
event.value = 28;
}
if (Land == "Äthiopien"){
event.value = 26;
}

----

Any hints why?

 

Kind regards

 

Matthias

Where did you put this script? Is it in a calculation script on the field you want to display the value?

What is happening?

Are any errors reported in the Console Window?

 

You're code should work, however, the "if" structure should be setup differently.

You'll find a tutorial on the Console Window here:

And this is an article on using the "if"

Hello Thom,

I have put the script in the user defined calculation field of a text field which i formated as as number. The script is not woking, no matter which format i use. It does not show any failures or errors, it just does not work. Any ideas?

 

 

Kind regards

Yes, First remove all formatting, you don't know if it is interfering with the calculation, so it's best to not use any formatting until you have the calculation working.

The field is showing a value "20,00", so something is happening. Somehow the first "if" condition is satisfied. 

 

Some things to consider.

1) If the items in the list have export values, then your code will not work.

2) If  the "Commit Selected Values Immediattely" option is not checked, then the calculation will only run when you click off of the dropdown. So make sure this is checked. 

 

And finally, did you watch the console window tutorial?  If none of the things I've covered so far help, then you need to add a "console.println" into the code to see exactly what values are returned from a list selection.
