Can the check boxes calculate a percentage number of items completed in PDF?

[AhmedCOSTA]

I have a simple list with checkboxes.

Is there a way to calculate a percentage complete based on the number of checkboxes were checked in one row?

If one checkbox is checked then it gives 25$

If two then 50%

If three then 75%

If all checked then 100%

Sure. Let's say the fields are called Drink1 to Drink4. You can then use this code for that calculation:

var max = 4;
var total = 0;
for (var i=1; i<=max; i++) {
	if (this.getField("Drink"+i).valueAsString!="Off") {
		total++;
	}
}
event.value = total/max;

You'll also need to set the text field as having the Percentage format.

Hi try67,

This is supper, Thanks alot.

But, what if the fields name is diffrent like:

KW MB POP - Dr 1

KS MB POP - Dr 1

QT MB POP - Dr 1

OM MB POP - Dr 1

[try67]

Then you need to hard-code them into the script, like this:

var fields = ["KW MB POP - Dr 1", "KS MB POP - Dr 1", "QT MB POP - Dr 1", "OM MB POP - Dr 1"];
var total = 0;
for (var i=0; i<fields.length; i++) {
	if (this.getField(fields[i]).valueAsString!="Off") {
		total++;
	}
}
event.value = total/fields.length;

[Edited: Code fixed]

SUPPER

It works great, just add the first two lines

var max = 4;
var total = 0;
var fields = ["KW MB POP - Dr 1", "KS MB POP - Dr 1", "QT MB POP - Dr 1", "OM MB POP - Dr 1"];
for (var i=0; i<fields.length; i++) {
	if (this.getField(fields[i]).valueAsString!="Off") {
		total++;
	}
}
event.value = total/fields.length;

Sorry, I accidentally removed the declaration of the total variable.

The max variable is no longer needed, though.

Hello, I would like to ask for assistance on my matter, it's similar to AhmedCOSTA's. 
Calculate the percentage of the checkboxes. 
For example; I have 19 checkboxes in total and if all of them are marked as checked. I want the field to get the percentage of 100%.

I followed Try67's code but I got the result 1,163% despite not ticking any of the boxes.

I don't see where you declared 'total' variable?

Other than that it looks ok, although it could be done slightly different.

[unisd53018312]

I see it now. Thank you, Nesa!
I made a mistake in not including the 'total' variable. 

Do you know how to keep that field blank if there's no checkboxes being ticked? 

Thanks again. 

[Nesa Nurani]

If you format the field as percentage, it can't be blank.

EDIT:

You can use this as custom format script instead:
if(event.value && parseFloat(event.value) != 0)
event.value = (parseFloat(event.value) * 100).toFixed(3) + "%";
else
event.value = "";

It works, Nesa. But it shows with decimals. Is there a way to not have decimals in the percentage?
Sorry, I didn't specify in my previous comment. 
I appreciate all the help. 

[unisd53018312]

Disregard my previous comment. 
Here's the script to achieve without decimal.

if(event.value && parseFloat(event.value) != 0)
event.value = (parseFloat(event.value) * 100).toFixed(0) + "%";
else
event.value = "";
