如何使用 JavaScript 從下拉列表中選擇文本和值。我想使用文本我會(huì)得到選定的下拉文本。就價(jià)值而言，它運(yùn)行良好。function myFunction() {  var x = document.getElementById("mySelect").value;  var y = document.getElementById("mySelect").text;  document.getElementById("demo").innerHTML = x;  document.getElementById("demo1").innerHTML = y;}<div>  <select id="mySelect">    <option value="1">Apple</option>    <option value="2">Orange</option>    <option value="3">Pineapple</option>    <option value="4">Banana</option>  </select>  <p>Click the button to return the value of the selected fruit.</p>  <button type="button" onclick="myFunction()">Try it</button>  <p id="demo"></p>  <p id="demo1"></p></div>
