Change Value of Field Based On Calculated Value

Recommended Posts

I have a calculated value field (SQFT) that calculates the square footage from user-inputted Width and Height values. I have another text field named SQFT_Override. I am trying to create a script that, if SQFT is less than 3 and not blank, then fill the SQFT_Override value with 3. I can't quite get it to work. 

First I was trying just a simple if statement with JS. I was able to change the value of SQFT_Override, but I couldn't get it to work with the second condition - SQFT can't be blank. I tried !== null and !== '' and couldn't get it to work. 

I also had a problem with the script only running once. If the width or height was changed afterwards, thus changing the SQFT value, SQFT_Override would still have '3' as its value. So, I tried wrapping it in a change event, but still can't get it to work. Below is my attempt. Any help would be appreciated.

document.addEventListener('DataPageReady', function (event) {
     document.querySelector('[id*="SQFT"]').addEventListener("change", sqftMinimum); 
      function sqftMinimum(event) {
          let checker = event.target.value;

          var putter = document.querySelector('[id*=SQFT_Override]');

          if (checker.innerText < 3 && checker.innerText !== null) {
          	putter.value = 3;
          } else { putter.value = '' }
