Javascript for Outputting "N/A" in a text field based on a choice

Hi @vities 

i have a question, do you need to edit this text when it has been populated? If not then a calculated value field will serve you much better here without using any JavaScript, you can just use a formula. 
 

if you do need to edit the text, for classic forms designer sadly JavaScript is the only option, 

Anyways, 

I think in your script the issue comes with the if statement looking at checked and then assessing the value of the check to set the status of each fruit, I don’t think it works this way.  

The val() function used on the checkbox input gets the value of the first checked box only. When working with multi-choice checkboxes, it’s possible to have multiple options selected so a single level if statement will almost always be incorrect. 

To fix your script, you should iterate through each checked option and then take action accordingly.

NWF.FormFiller.Events.RegisterAfterReady(function () {
    NWF$('#'+varFruits).change(function(){   
        // Reset all values to 'In Stock' first
        NWF$('#'+varApple).val('In Stock');
        NWF$('#'+varOrange).val('In Stock');
        NWF$('#'+varPear).val('In Stock');

        // Then go through each checked option
        NWF$('#'+varFruits + ' input:checked').each(function(){
            if (this.value == 'Apple') {
                NWF$('#'+varApple).val('N/A');
            } else if (this.value == 'Oranges') {
                NWF$('#'+varOrange).val('N/A');
            } else if (this.value == 'Pear') {
                NWF$('#'+varPear).val('N/A');
            }
        });
    });
});

Ah, I misunderstood the requirement, let me validate it and get back to you. 

Hi Jake,

   Thank you so much again for your help/reformatting! Is it possible to leave the initial setting of the fields to be blank, or do they need to be defined with a value?

If the item is not out of stock, they’ll enter a numeric value (i.e. stock quantity). Otherwise, when they checkmark the boxes, it’s to denote that “Hey, it’s out of stock!” therefore the stock quantity is N/A.

 Also, even when I test the script, I’m not able to get it to output in the same format as yours:

Copied the code into Settings - Form (Custom Javascript):

Selected the multi-choice field, and assigned the variable to be: 

Selected the text field for Apples Stock, and assigned the variable to be:

Am I doing something wrong?

Thanks!
