I am doing to change 2nd select tag name by javascript.
this is my HTML
1st select
<select name="bank" id="bank" class="select" onchange="myFunction(event)">
<option value="Bank Account" a="required">Bank Account</option>
<option value="UPI" a="hidden">UPI</option>
</select>
2nd Select
<select name="bank1" class="select" id="bank1" required>
<option disabled selected>Choose Bank Name</option>
<option value="SBI">SBI</option>
<option value="PNB" >PNB</option>
</select>
this is my javascript
function myFunction(e) {
document.getElementById("bank1").name = e.target.a
but i want to change in 2nd select required to hidden
Do you want to hide the second select box completely?
function myFunction(e) {
document.getElementById("bank1").classList.add("hidden")
}
CSS
#bank1.hidden {
display:none;
}
probably you are looking for setAttribute.
document.getElementById("bank1").required = false;
And for style mutation. As @Kokodoko had already written.
document.getElementById("bank1").classList.add("hidden")
