解决layui中table异步数据请求不支持自定义返回数据格式的问题

//获得数据Class.prototype.pullData = function(curr, loadIndex){ var that = this  ,options = that.config  ,request = options.request  ,response = options.response  ,sort = function(){  if(typeof options.initSort === 'object'){   that.sort(options.initSort.field, options.initSort.type);  } };  that.startTime = new Date().getTime(); //渲染开始时间  if(options.url){ //Ajax请求  var params = {};  params[request.pageName] = curr;  params[request.limitName] = options.limit;   //参数  var data = $.extend(params, options.where);  if(options.contentType && options.contentType.indexOf("application/json") == 0){ //提交 json 格式   data = JSON.stringify(data);  }   $.ajax({   type: options.method || 'get'   ,url: options.url   ,contentType: options.contentType   ,data: data   ,dataType: 'json'   ,headers: options.headers || {}   ,success: function(res){    // 加入这部分！！！    // 临时解决layui的table组件中response选项不支持多层级获取接口数据的方法    // ----------------开始---------------------    if (typeof options.responseHandler == "function") {     res = options.responseHandler(res);    }    // ----------------结束---------------------     if(res[response.statusName] != response.statusCode){     that.renderForm();     that.layMain.html('<div class="'+ NONE +'">'+ (res[response.msgName] || '返回的数据状态异常') +'</div>');    } else {     that.renderData(res, curr, res[response.countName]), sort();     options.time = (new Date().getTime() - that.startTime) + ' ms'; //耗时（接口请求+视图渲染）    }    loadIndex && layer.close(loadIndex);    typeof options.done === 'function' && options.done(res, curr, res[response.countName]);   }   ,error: function(e, m){    that.layMain.html('<div class="'+ NONE +'">数据接口请求异常</div>');    that.renderForm();    loadIndex && layer.close(loadIndex);   }  }); } else if(options.data && options.data.constructor === Array){ //已知数据  var res = {}   ,startLimit = curr*options.limit - options.limit   res[response.dataName] = options.data.concat().splice(startLimit, options.limit);  res[response.countName] = options.data.length;   that.renderData(res, curr, options.data.length), sort();  typeof options.done === 'function' && options.done(res, curr, res[response.countName]); }};

responseHandler: function (res) { // 可进行数据操作 return {  "count": res.data.count,  "data": res.data.companyList,  "code": res.code == 200 ? 0 : -1 //code值为200表示成功 };},
