Javascript函数获取输入值

Question

我编写了带有多个按钮的代码，每个按钮都有不同的值。我正在尝试在 javascript 函数中获取该值。

  <form action="https://www.bing.com" method="get">
    <input class="input" type="text" name="q" id="field" autofocus>
    <div class="buttons">
      <input type="submit" class="button" id="x1" name="x1" value="Bing"> 
      <input type="submit" class="button" id="x2" name="x2" value="Google">
      <input type="submit" class="button" id="x3" name="x3" value="Yahoo"> 
      <input type="submit" class="button" id="x4" name="x4" value="Duck">
      <input type="submit" class="button" id="x5" name="x5" value="Ask"> 
      <input type="submit" class="button" id="x6" name="x6" value="Aol.">
    </div>
  </form>
</div>

<script>
  var form = document.querySelector('form');
  var input = document.getElementById('field');
    var x = document.getElementById('x1').value;

  form.addEventListener('submit', function(ev) {
    ev.preventDefault();

    if(x=="Bing") {

    var redirect = 'https://google.com/search?q=' + input.value; }

    window.location = redirect;
  });
</script>

这里的输入提交仅在单击时才设置值？如果我尝试将所有提交按钮 id 命名为 xx，那么我可以获取函数中单击的按钮。我想在单击相应的提交按钮后执行不同的重定向。 (多次提交操作:这个问题不重复，是JS特有的，这种情况)

尝试这样。为我工作

    <input class="input" type="text" name="q" id="field" autofocus>
    <div class="buttons">
      <input type="submit" class="button" id="x1" name="x1" value="Bing"> 
      <input type="submit" class="button" id="x2" name="x2" value="Google">
      <input type="submit" class="button" id="x3" name="x3" value="Yahoo"> 
      <input type="submit" class="button" id="x4" name="x4" value="Duck">
      <input type="submit" class="button" id="x5" name="x5" value="Ask"> 
      <input type="submit" class="button" id="x6" name="x6" value="Aol.">
    </div>

</div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>


<script>

$(".button").on("click", function(e){
e.preventDefault();
var x = $(this).attr("value");
var redirect = "" 
if (x=="Google")
{

 window.location = "https://google.com/search?q=" + $(".input").val();

}

});

</script>

扩展 if 条件以获得更多搜索选项。

谢谢
