The example in this article describes the method of using javascript to change the button to display text after clicking. Share it with everyone for your reference. The specific implementation method is as follows:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
 <title>显示一些按钮,如果点击了,
 当前点击的按钮文本变为“点了”,其他按钮文本变为“没点”</title>
 <script type="text/javascript">
 //为所有按钮动态添加事件
 function IniButtonEvent() {
  var Items = document.getElementsByTagName("input");
  for (var i = 0; i < Items.length; i++) {
  var objTmp = Items[i];
  if (objTmp.type == "button") {
   objTmp.onclick = ButtonClick;
  }
  }
 }
 function ButtonClick() {
  var Items = document.getElementsByTagName("input");
  for (var i = 0; i < Items.length; i++) {
  var objTmp = Items[i];
  if (objTmp.type == "button") {
  //判断是否是按钮
   //window.event.srcElement触发当前事件的元素
   //用来判断是否是当前单击的按钮
   if (objTmp == window.event.srcElement) {
   objTmp.value = "点了";
   }
   else {
   objTmp.value = "没点";
   }
  }
  }
 }
 </script>
</head>
<body onload="IniButtonEvent()">
显示一些按钮,如果点击了,当前点击的按钮文本变为“点了”,
其他按钮文本变为“没点”<br />
 <input type="button" value="没点" />
 <input type="button" value="没点" />
 <input type="button" value="没点" />
 <input type="button" value="没点" />
 <input type="button" value="没点" />
</body>
</html>
