javascript - Remove item from dropdown list on page load (no jquery)

Question

I have the following dropdown list:

<select name="DD1" id="DD1">
    <option value="B">B</option>
    <option value="D">D</option>
    <option value="E">E</option>
    <option value="F">F</option>
    <option value="R">R</option>
</select>

On page load I need to hide/delete option D. I can't go by the index because that list is dynamic so I have to use the value parameter or the actual text that gets rendered.

I've tried finding the answer but all the solutions I came across use JQuery for this and I don't have the option to do this.

Anyone have a way to hide option D just using Javascipt on page load so the user never sees that option?

Thanks

Answer 1

var select=document.getElementById('DD1');

for (i=0;i<select.length;  i++) {
   if (select.options[i].value=='D') {
     select.remove(i);
   }
}
