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=radio22、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>
