在线等，谢谢了各位，关于js的input的value

JScript code

<HTML> <HEAD>  <TITLE> test </TITLE>   </HEAD> <BODY>    <script language="javascript">        function getNumber()            {                alert();            }    </script> </BODY>    <form name = "myForm">        <input type = "button" name = "myButton" value = "1">        <input type = "button" name = "myButton" value = "2">        <input type = "button" name = "myButton" value = "3">    </form></HTML>

请问各位大侠如何用js弹出每个input的值啊？

[解决办法]
首先你的所有button不要用同一个名称（name）---建议

获取方法：

JScript code

function getNumber(){   var t = document.getElementsByTagName("input");   for(var i=0; i<t.length; i++){      alert(t[i].value);   }}
[解决办法]
HTML code<HTML><HEAD><TITLE> test </TITLE><script language="javascript">function showSingleInputValue(n){  alert('第三个Input的值为：'+document.getElementsByTagName("myButton")[n].value);}function showAllInputValue(){  var o = document.getElementsByTagName("INPUT");//取得所有Input对象集合；  var arr=[];//定义一个数组用来存放Input对象值  for(var i=0; i<o.length; i++){    arr.push(o[i].value);//将各个Input对象值压入数组        }  document.getElementsByName("myText")[0].value=arr.jion(",")  alert('共有'+o.length+'个Input对象，其值分别为：'+arr);}window.onload=function(){  showAllInputValue()//页面加载完毕后显示所有Input对象的值}</script>  </HEAD> <BODY>    <form name = "myForm">        <input type = "text" name = "myText" value = "0">        <input type = "button" name = "myButton" value = "1">        <input type = "button" name = "myButton" value = "2">        <input type = "button" name = "myButton" value = "3">    </form>    <input type = "button" name = "showSingleButtonValue" value = "显示第三个Input对象的值" onclick="showSingleInputValue(2)"  /> </BODY></HTML>
