WebService直接这么输出
-----------------------------------------------------------------------
json: pz_xmljson xj = new pz_xmljson(); Context.Response.Write(xj.toJson("value",tmp)); //xj.jsonLoad(SqlDataReader sdr) Context.Response.End();
jquery ajax这么拿值
-----------------------------------------------------------------------
$.ajax({ url: "WebService.asmx/******",type: "POST",data: { receiverid: 。。。。,key: 。。。。 },dataType: "json",success: function(result) { result[0].value 。。。。。 } 多个值的话用 $.each(result,function(i,n) { n.Name。。。。 n.ID。。。。。 n.***。。。。。 }
