ajax请求里的contentType: "application/json"作用

对于页面中复杂数据的提交：

$.ajax({

type:"post",

url:url,

dataType: "json",

contentType: "application/json",

async:true,

data:JSON.stringify(param),

success:function(result){

if(result.code == "0"){

var rows = result.data;

if(typeof successcallback == ‘function‘){successcallback(rows);}else{alert(result.msg);}

}else{

alert(result.msg);

}

error:function(jqXHR, textStatus, errorThrown){

//alert("提交失败，请重试！");

}

});

需要通过JSON.stringify(param)把页面中获取的参数变成json字符串,，此时需要加上contentType: "application/json",
