Auto check the Check box depending of the value of the dropdown


Recommended Posts

To implement such a workflow you need to add Header/Footer and insert this little snippet of code into the footer. Note that "HTML Editor" needs to be disabled.

 

<script>

   document.getElementById('cbParamVirtual1').addEventListener("change", function() {
      if (document.getElementById('cbParamVirtual1').value == 'Choice_1') {
         document.getElementById('cbParamVirtual20').checked = true;
      } else if (document.getElementById('cbParamVirtual1').value == 'Choice_2' || document.getElementById('cbParamVirtual1').value == 'Choice_3') {
         document.getElementById('cbParamVirtual21').checked= true;
      } else {
         document.getElementById('cbParamVirtual20').checked = false;
         document.getElementById('cbParamVirtual21').checked = false;
      }
   });

</script>

You need to choose your own ID values of elements using Developer tools of a browser.
Also, you need to adjust the values of Dropdown in the code according to your adjustments in the Dropdown.

This code can be adjusted depending on the amount of the choices if the Dropdown and CheckBox.

 

<script>

   document.getElementById('cbParamVirtual1').addEventListener("change", function() {
      if (document.getElementById('cbParamVirtual1').value == 'Choice_1') {
         document.getElementById('cbParamVirtual20').checked = true;
      } else if (document.getElementById('cbParamVirtual1').value == 'Choice_2' || document.getElementById('cbParamVirtual1').value == 'Choice_3') {
         document.getElementById('cbParamVirtual21').checked= true;
      } else if (document.getElementById('cbParamVirtual3').value == 'Choice_3' || ... || document.getElementById('cbParamVirtualX').value == 'Choice_X') {
         document.getElementById('cbParamVirtualX').checked= true;
      } else {
         document.getElementById('cbParamVirtual20').checked = false;
         document.getElementById('cbParamVirtual21').checked = false;
         .
         .
         .
         document.getElementById('cbParamVirtual2X').checked = false;
      }
   });

</script>
