正确答案后重设选择选项

Question

Long time listener, first time caller...I have a music test that asks the user to identify a pitch and after the correct answer, I need the select option's value to reset to 'disabled selected.' Have tried multiple things but no luck. Any help would be greatly appreciated!

 $("#pitchBtn").click(function() { if (gameFinished) { // Clear the value of the option in the select element here } } 

 <select id="selectText"> <option value="" disabled selected>Enter your guess</option> <option value="C"></option> <option value="D">D</option> <option value="E">E</option> </select> 

Answer 1

Try

var element = document.getElementById('selectText');
element.value = "";

Answer 2

I'd suggest:

// cache the relevant <option> element,
// retrieve that element using
// document.querySelectorAll() to select
// the first, if any, element matching the
// supplied CSS selector:
let defaultOption = document.querySelectorAll('option[value=""]');

// set the 'selected' property to true:
defaultOption.selected = true;

// set the 'disabled' property to true:
defaultOption.disabled = true;
