AJAX为什么返回的是整个页面的HTML？

Question

代码如下： var geolocation = new BMap.Geolocation(); geolocation.getCurrentPosition(function(r){ if(this.getStatus() == BMAP_STATUS_SUCCESS){ //主要用来获取r.point.lat和r.point.lng这两个经纬值 $.ajax({ url:'list.php?fid=$fid', data: {'lng':r.point.lng,'lat':r.point.lat}, type:'get', async:false, success:function(d){ alert(d); } }); else { alert('failed'+this.getStatus()); } },{enableHighAccuracy: true}); 我的PHP文件里(list.php)是MYSQL查询语句和while循环。我上面代码获取的经纬度是用来在mysql查询语句里与商家设置的经纬度计算获取距离用的，PHP里使用$_GET['lng']在AJAX返回值里可以获取到那两个值（我通过alert(d)可以看到商家列表里计算出的距离），可问题出现了。如果获取不到上面的lat和lng就会错误并在前端打印出MYSQL所有语句。如果我$('body').html(d);就会出现AJAX无限自动刷新加载整个页面。（初步认为可能是在执行AJAX的时候因为返回的是整个HTML页面，所以AJAX又再一次执行了一次，如此造成不断刷新加载）。 请问，我该如何解决这个问题呢？先谢谢啦！~ PHP文件 <?php define('MOB_PAGE',true);

Answer 1

猜测是不是直接去请求list.php静态文件了而且又是get。
不知道你能不能把数据的接口跟页面的分开。

Answer 2

给个dataType:xxx啦

dataType表示你希望给服务器回复给你的 是什么类型的数据 如果你不给 他就给你默认了

Answer 3

有一种可能是后台出错了 返回的是dubeg页面

Answer 4

$.ajax({
    type: "post",  //数据提交方式（post/get）
    url: "demo.php",  //提交到的url
    data: {username:username,password:password},//提交的数据
    dataType: "json",//返回的数据类型格式
    success: function(msg){
      ...//返回成功的回调函数
    },
    error:function(msg){
      ...//返回失败的回调函数
    }
});```
