从选项列表中过滤一些前缀

Question

我无法从我网页上的选项列表中删除前缀编号 100-199 和 200-299。

下面的代码是我试过的：

<select id="category_cabinet" name="category_cabinet" class="form-control" onchange="change_cabinet_search(this.value)">

<option value="0">Please Select</option>

<option value="658">100-PENTADBIRAN</option>

<option value="659">200-PENGURUSAN TANAH &amp; BANGUNAN</option>

<option value="660">300-PENGURUSAN ASET</option>

<option value="661">400-PENGURUSAN KEWANGAN</option>

<option value="662">500-PENGURUSAN SUMBER MANUSIA</option>

<option value="663">100-1-PENTADBIRAN/PERUNDANGAN</option>

<option value="664">100-2-PENTADBIRAN/PERHUBUNGAN AWAM</option>

<option value="679">516-JOHN</option><option value="680">516-1-JOHN/DAVID</option>                      

</select>

<script>

let select = document.querySelector('#category_cabinet').children

for ( let el of select){

  if (el.textContent.match(/^[12]/)) el.remove()

}

</script>

结果显示如下图所示：

即一些条目被过滤掉（例如，第一个选项 100-PENTADBIRAN 未显示），但仍包含一些与我的正则表达式匹配的条目。

如何显示如下图所示的结果：

即删除所有与代码中的正则表达式匹配的选项？
