JQuery.Ajax()的data参数类型实例详解

<form id='addForm' action='UserAdd.action' type='post'>   <label for='uname'>用户名</label>：<input type='text' name='uname' id='uname'><br>   <label for='mobileIpt'>手机号：</label><input type='text' name='mobileIpt' id='mobileIpt'><br>   <label for='birthday'>生日：</label><input type='text' name='birthday'><br>   <input type='button' value='提交' onclick='addUser()'></form>

function addUser(){    var user = {      uname:$("#uname").val(),      mobileIpt:$("#mobileIpt").val(),      birthday:$("#birthday").val()    };    $.ajax({      url:'UserAdd.action',      data:user,      type:'post',      dataType:'text',      success:function(msg){        if(msg=='1'){          console.log('添加成功');        }else{          console.log('添加失败')        }      }    })  }

$('#addForm').serializeArray();//返回数据结构，是json数组，每个对像分别name和value为key，代表这个表单元素的name和value[  {"name":"uname","value":""},  {"name":"mobileIpt","value":""},    {"name":"birthday","value":""}]

var arr = $('#addForm').serializeArray();$.param(arr);"uname=alice&mobileIpt=110&birthday=1983-05-12"

返回值:StringjQuery.param(obj,[traditional])将表单元素数组或者对象序列化。参数obj,[traditional]数组或jQuery对象会按照name/value对进行序列化，普通对象按照key/value对进行序列化。traditional:是否使用传统的方式浅层序列化。demo:$.param({uanme:'vic',mobileIpt:'110',birthday:'2013-11-11'});"uanme=vic&mobileIpt=110&birthday=2013-11-11"

$.param([{uanme:'vic'},{mobileIpt:'110'},{birthday:'2013-11-11'}]);"undefined=&undefined=&undefined="

//在ajax()方法中，对json类型的数据进行了$.param()处理if ( s.data && s.processData && typeof s.data !== "string" ) {  s.data = jQuery.param( s.data, s.traditional );}//param方法中if ( jQuery.isArray( a ) || ( a.jquery && !jQuery.isPlainObject( a ) ) ) {    // Serialize the form elements    jQuery.each( a, function() {      add( this.name, this.value );    });  } else {    // If traditional, encode the "old" way (the way 1.3.2 or older    // did it), otherwise encode params recursively.    for ( prefix in a ) {      buildParams( prefix, a[ prefix ], traditional, add );    }  }

[  {"name":"uname","value":"alice"},  {"name":"mobileIpt","value":"110"},    {"name":"birthday","value":"2012-11-11"}]

$.ajax({  type: post,  url: some.php,  data: name=john&location=boston, //第一种方式传参 // data: {name:john,location:boston} //第二种方式传参 // data: {foo:[bar1, bar2]} 转换为 '&foo=bar1&foo=bar2' /* 第一种我们用url传参，参数里面如果加带&这个符号地话，可能参数接收不到或不完整， 如“ data: name=john&location=boston,” 如果name地值是john&smith这样写可能就会有问题， 我们可以用js里面地encodeuricomponent()方法进行转义， 但如果用data: {name:john,location:boston}这种方式写地话就不需要进行转义， 如果转义地话，接收地将是转义后地字符串 */  success: function(msg){   alert( data saved: + msg );  }});
