<form name="form1" onsubmit="show()"> ..... <input type="submit" name="submit" id="submit" value="添加"> <input type="submit" name="submit" id="submit" value="修改"> </form>
<script language="javascript"> function show() { if (document.form1.submit.value=="添加") { alert("你点的是提交"); } else { alert("你点的是修改"); } } </script>
方法二：未验证
<input type=hidden name=whatButton> <input type=submit onlick="whatButton.value=this.value" value="aaa"> <input type=submit onlick="whatButton.value=this.value" value="bbb"> <input type=submit onlick="whatButton.value=this.value" value="ccc">
