我想在<select>字段上执行一个on change事件。根据选择的值，我想过滤另一个<select>字段。现在我知道如何实现这一点，任何帮助，请。

不知道你到底想要什么

检查代码片段，这是我从你的问题声明中得到的理解

window.onload = function() {
  var choose_one = document.getElementById("select_one");
  choose_one.addEventListener("change", ChangedOption);
}
function ChangedOption() {
  var choose_one = document.getElementById("select_one");
  var choose_two = document.getElementById("select_two");
  var selectedIndex = choose_one.selectedIndex;
  if (selectedIndex > -1) {
    var selectedValue = choose_one.options[choose_one.selectedIndex].value;
    var selectTwoOptions = choose_two.options;
    for (var i = 0; i < choose_two.options.length; i++)
      if (selectTwoOptions[i].value == selectedValue) {
        selectTwoOptions[i].selected = true;
      }
    
  }
}

<select id="select_one">
  <option value="1">one</option>
  <option value="2">two</option>
  <option value="3">three</option>
</select>
<select id="select_two">
  <option value="4">four</option>
  <option value="3">three</option>
  <option value="5">five</option>
</select>

希望能有所帮助
