跨域问题hbuilder

1.借助jquery-jsonp插件

$.jsonp({
url: url,
data: {
'name': usd,
'passwd': pass
},
callbackParameter: "callback",
success: function(newImgSrc, textStatus, xOptions) {
alert(444);
console.log(xOptions.data.imgSrc);
},
error: function(xOptions, textStatus) {}
});

　　

后台代码：

        Gson gson =   new GsonBuilder().setDateFormat("yyyy-MM-dd HH:mm:ss")
        .create(); 

        String ster="result:"+gson.toJson(result);
        return "callbackJieduanList({'message':'获取成功','state':'1',"+ster+"})";

callbackJieduanList 为html前端的js方法

2.hbuilder

          function testXHR(){
              if(xhr){
                  return;

          }

              if (xhr.readyState==4&&xhr.status == 200) {

                      data = JSON.parse(xhr.responseText);

                      //alert(data.a1)
                      for(i in data){alert(data[i])}

              }
          }
