Question

如何找出点击的按钮。

`<input type="submit" name="quest" id="ques" value="quest" />
<input type="submit" name="answer" id="ans" value="answer"  />`

Answer 1

很容易就像我一样编码

代码：

<html>
   <head>
      <script language="javascript">         
         function checkBtn(event) {
               alert(event.target.name);
         }
      </script>


   </head>
   <body>
      <br /><br />
      <form action="multiSubmit.php" method="post" onSubmit="return false;">
         <input type="submit" name="quest" id="quest" value="quest" onClick="checkBtn(event)" /><br />
         <input type="submit" name="answer" id="answer" value="answer" onClick="checkBtn(event)" /><br />
      </form>

   </body>
</html>

Answer 2

代码应如下所示

<script language="javascript">         
   function checkBtn(event) {
         alert(event.target.name);
     }
</script>

在每个按钮上添加onClick="checkBtn(event)"。否则，您可以像onsubmit

一样在表单中添加onSubmit="checkBtn(event)"

Answer 3

以下代码是检查单击哪个按钮的解决方案。

document.getElementById('button').onclick = function() {
   alert("button was clicked");
};

要找到在javascript php中单击的按钮
