1.获取input值 的6种方法：
<!doctype html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>测试页面</title>
<script type="text/javascript" src="jquery.js"></script>
</head>
<body>
<div id="gjdiv" class="gjc">
<input type="hidden" id="title" name="gj" value="113"/>
<input type="hidden" id="brief" name="gj" value="df"/>
<input type="hidden" id="content" name="gj" value="sg"/>
</div>
<script>
$(document).ready(function(){
var param0 = $("input[name='gj']").val();
console.log("param0:"+param0);
var param1 = $(".gjc input[name='gj']").val();
console.log("param1:"+param1);
var param2 = $("#gjdiv input[name='gj']").val();
console.log("param2:"+param2);
var param3 = $("div input[name='gj']").val();
console.log("param3:"+param3);
var param4 = $("#gjdiv>input[name='gj']").val();
console.log("param4:"+param4);
var param5 = $("#gjdiv :input[name='gj']").val();
console.log("param5:"+param5);
console.log("stringify():"+JSON.stringify(param0));
//console.log(JSON.parse(param));
})
</script>
</body>
</html>
获取的都是第一个input的值。
2.将input值序列化：
<!doctype html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>测试页面</title>
<script type="text/javascript" src="jquery.js"></script>
</head>
<body>
<div id="gjdiv" class="gjc">
<input type="hidden" id="title" name="gj" value="113"/>
<input type="hidden" id="brief" name="gj" value="df"/>
<input type="hidden" id="content" name="gj" value="sg"/>
</div>
<script>
$(document).ready(function(){
var param0 = $("input[name='gj']").serialize();
console.log("param0:"+param0);
var param1 = $(".gjc input[name='gj']").serialize();
console.log("param1:"+param1);
var param2 = $("#gjdiv input[name='gj']").serialize();
console.log("param2:"+param2);
var param3 = $("div input[name='gj']").serialize();
console.log("param3:"+param3);
var param4 = $("#gjdiv>input[name='gj']").serialize();
console.log("param4:"+param4);
var param5 = $("#gjdiv :input[name='gj']").serialize();
console.log("param5:"+param5);
console.log("stringify():"+JSON.stringify(param0));
//console.log(JSON.parse(param));
})
</script>
</body>
</html>
结果：
