How do I programmatically set the value of a select box element using JavaScript?

Posted By: brass-kazoo

I have the following HTML <select> element:

<select id="leaveCode" name="leaveCode">
  <option value="10">Annual Leave</option>
  <option value="11">Medical Leave</option>
  <option value="14">Long Service</option>
  <option value="17">Leave Without Pay</option>
</select>

Using a JavaScript function with the leaveCode number as a parameter, how do I select the appropriate option in the list?

Solution

You can use this function:

selectElement('leaveCode', '11')

function selectElement(id, valueToSelect) {    
    let element = document.getElementById(id);
    element.value = valueToSelect;
}
