简单获取input标签的所有属性代码

1.用jquery

$("input[name='btnAdd']").attr("value")

获取value属性值，其它属性换attr的参数就OK

例：

<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<script type="text/javascript" src="jquery.js"></script> 
</head>
<body>
<div class="box">
<span>点击按钮获取文本框的name属性值：</span><br>
<div class="content">
<input type="text" name="test" value="这个文本框的name属性值为test">
</div>	
<input type="button" class="btn" value="获取文本框name值">
</div>
<script>
$(function(){
$("input:button").click(function() {
alert($("input:text").attr("name"));
});
})

 

</script>
</body>
</html>

2.通过点来获取：

<!doctype html>
<html lang="en">
 <head>
  <meta charset="UTF-8">
  <title>Document</title>
 </head>
 <body>
  <form id="form1" name="form1">
<input name="n1" type="text" />
<input name="n3" type="text" />
<input name="n4" type="text" />
</form>


<script>
window.onload = function(){
    var inputs = document.form1.getElementsByTagName("input");
    for(var i = 0; i < inputs.length; i++) {
        inputs[i].onclick = function(){
            alert(this.name);
        };
    }
};

</script>
 </body>
</html>
