1. Use jquery

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

Obtain the value attribute value, and exchange other attributes for attr parameters to OK

2. Get by dots:


<!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>
