1、serialize()把表单的值序列化成字符串
<html>
<head>
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
</head>
<body>
<p id="results"><b>Results: </b> </p>
<form>
<select name="single-name">
<!--这一段序列化为字符串的结果是：name=text 在这里，默认选中的是Single1——> single-name=Single1-->
<option>Single1</option>
<option>Single2</option>
</select>
<select name="multiple-name" multiple="multiple">
<!--这一段序列化为字符串的结果是：name=text 在这里——> multiple-name=Multiple1&multiple-name=Multiple3-->
<option selected="selected">Multiple1</option>
<option>Multiple2</option>
<option selected="selected">Multiple3</option>
</select><br/>
<input type="checkbox" name="check-name" value="check1" checked="checked"/> check1111
<!--这一段序列化为字符串的结果是：name=value——>check-name=check1-->
<input type="checkbox" name="check-name" value="check2" checked="checked"/> check2222
<!--这一段序列化为字符串的结果是：name=value——>chec-namek=check2-->
<input type="radio" name="radio-name" value="radio1" checked="checked"/> radio1111
<!--这两段只能同时选中一个，序列化为字符串的结果是：name=value——>radio-name=radio1-->
<input type="radio" name="radio-name" value="radio2" checked="checked"/> radio2222
</form>
<script>
$("#results").append( "<tt>" + $("form").serialize() + "</tt>" );
</script>
</body>
</html>
最终序列化成字符串的结果是：single-name=Single1&multiple-name=Multiple1&multiple-name=Multiple3&check-name=check1&check-name=check2&radio-name=radio2 2、serializeArray()把表单的值序列化成JSON对象，是对象哦
<html>
<head>
<meta charset="utf-8">
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
</head>
<body>
<p id="results"><b>Results: </b> </p>
<form>
<select name="single">
<option>Single</option>
<option>Single2</option>
</select>
<select name="multiple" multiple="multiple">
<option selected="selected">Multiple</option>
<option>Multiple2</option>
<option selected="selected">Multiple3</option>
</select><br/>
<input type="checkbox" name="check" value="check1"/> check1
<input type="checkbox" name="check" value="check2" checked="checked"/> check2
<input type="radio" name="radio" value="radio1" checked="checked"/> radio1
<input type="radio" name="radio" value="radio2"/> radio2
</form>
<script>
var fields = $("select, :radio").serializeArray();
jQuery.each( fields, function(i, field){
alert(JSON.stringify(field));
$("#results").append(field.value +" ");
});
</script>
</body>
</html>
