从页面加载下拉列表中删除项目(无jquery)

问题描述:

我有以下的下拉式清单:

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>

在页面加载时,我需要隐藏/删除选项D.我不能按索引去该列表是动态的,所以我必须使用value参数或渲染的实际文本。

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.

我试过找到答案,但是我遇到的所有解决方案都是使用JQuery来完成的,我没有这个选项。

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.

任何人都有办法在页面加载时使用Javascipt隐藏选项D,所以用户从不会看到该选项?

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

p>

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

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