Joget DX 8 Stable Released
The stable release for Joget DX 8 is now available, with a focus on UX and Governance.
In this article. we will show you how to hide a value in the second select box based on the chosen value in the first select box.
You can use the following script in a custom HTML field:
<script> $(document).ready(function(){ // Get references to the select boxes var approver1 = (document.getElementsByName("approver_1"))[0]; var approver2 = (document.getElementsByName("approver_2"))[0]; // Add change event listener to the select box approver1.addEventListener("change", function() { updateApprover2Options(approver1,approver2); }); // Initial call to set the correct options on page load updateApprover2Options(approver1,approver2); }) // Function to update approver2 options based on approver_1 selection function updateApprover2Options(approver1,approver2) { var selectedValue = approver1.value; // Loop through approver2 options to hide/show based on approver1 selection for (var i = 0; i < approver2.options.length; i++) { var option = approver2.options[i]; // reset each option display incase of new value update option.style.removeProperty('display'); // apply the hide display here if (option.value === selectedValue) { console.log("hiding value "+option.value+" : "+selectedValue); option.style.display = 'none'; // Hide the option } } } </script>
Make sure to have 2 select boxes in the form with the following id "approver_1" and "approver_2"
Figure 1: approver_1
Figure 2: approver_2
In runtime, you can see "Cat" does not appear in the Approver 2 select box.
