DataTables warning: table id=dataTable - Requested unknown parameter ‘acceptId’ for row 0. For more information about this error, please see http://datatables.net/tn/4
使用jquery.datatable时发生上面错误,配置如下:
table = $("#dataTable").dataTable({ "scrollY": "400px", //高度 "scrollX": true, //左右滚动条 "ordering":false,//thead上的排序按钮 "bLengthChange": false,//分页条数选择按钮 "bProcessing": true,//显示加载中 "bInfo": false,//页脚信息显示 "searching":false,//搜索输入框显示 "sPaginationType": "full_numbers",//分页显示样式 "paging":true,// "sAjaxSource": '<%= basePath %>sellcar/getSellCarOrderList', "bProcessing" : true, "bServerSide" : true, "oLanguage": { "sLengthMenu": "每页显示 _MENU_ 条", "sZeroRecords": "没有找到符合条件的数据", "sProcessing": "我也是醉了，正在加载数据...", "sInfo": "当前第 _START_ - _END_ 条 共计 _TOTAL_ 条", "sInfoEmpty": "没有有记录", "sInfoFiltered": "(从 _MAX_ 条记录中过滤)", "sSearch": "搜索：", "oPaginate": { "sFirst": "首页", "sPrevious": "前一页", "sNext": "后一页", "sLast": "尾页" } }, "aoColumns": [ //{ "sDefaultContent": ' '}, { "mData":"brandName",'sClass':'left', "mRender":function(data,type,full) { var cusId = full.customerId; var sellNo = full.sellNo; var content = "<td><input type='checkbox' name='batchAllocated' id='batchAllocated' value='"+cusId+"' sell_no='"+sellNo+"'></td>"; return content; } }, { "mData":"brandId", "mRender":function(data,type,full){ if(full.carBrand!=null){ return full.carBrand.brandName; }; return ""; } }, { "mData":"serieId", "mRender":function(data,type,full){ if(full.carSerie!=null){ return full.carSerie.serieName; }; return ""; } }, { "mData":"customeId", "mRender":function(data,type,full){ if(full.customer!=null){ return full.customer.userName; }; return ""; } }, { "mData":"phoneNo"}, { "mData":"createdFormat"}, { "mData":"sellStatus",'sClass':'left', "mRender":function(data,type,full) { var sellStatus = full.sellStatus; var content = ""; if(sellStatus==0){ content = "待估车"; }else if(sellStatus==10){ content = "估车成功"; if(full.recordStatus == "wlr"){ content = "估车成功，未录入"; }else if(full.recordStatus == "ylr"){ content = "已录入"; } if(full.item !=null){ var item = full.item; if(item.carStatus == "ysh"){ content = "通过审核"; if(item.carOnSale == 0){ content = "待上架"; }else if(item.carOnSale ==1){ content ="上架"; }else if(item.carOnSale == 2){ content = "下架"; }else if(item.carOnSale == 3){ content = "已售"; }else if(item.carOnSale == 4){ content = "申请下架"; } }else if(item.carStatus =="dsh"){ content = "待审核"; }else if(item.carStatus == "wsh"){ content = "未通过审核"; } } }else if(sellStatus==20){ content = "重新估车"; }else if(sellStatus == 30){ content = "估车失败，结束"; }else if(sellStatus == 40){ content = "无效信息"; } return content; } }, { "mData":"acceptId", "mRender":function(data,type,full){ if(data !=null){ if(full.acceptUser !=null){ return full.acceptUser.userName; } } } }, { "mData":"carStatus",'sClass':'left', "mRender":function(data,type,full) { var content = "<a href='javascript:void(0);' class='show_info' info_id='"+full.sellNo+"'>查看</a>"; return content; } }, { "mData":"isAllocated",'sClass':'left', "mRender":function(data,type,full) { var isAllocated = full.isAllocated; var content = ""; if(isAllocated==0){ content = "<a href='javascript:void(0);' class='change_info' info_id='"+full.sellNo+"' cus_id='"+full.customerId+"'>分配</a>"; }else{ content = "<a href='javascript:void(0);' class='change_info' info_id='"+full.sellNo+"' cus_id='"+full.customerId+"'>重新分配</a>"; } return content; } }],// "bLengthChange": true,// 控制每页显示记录数 "iDisplayLength": 10, // 每页显示数量 "fnServerData" : function(sSource, aoData, fnCallback) { $.ajax({ "type" : 'post', "url" : sSource, "dataType" : "json", "data" : { aoData : JSON.stringify(aoData), searchData: JSON.stringify(searchData) }, "success" : function(resp) { fnCallback(resp); var datas=resp.aaData; }, error: function(resp){ } }); }/* , "fnRowCallback": function(nRow, aData, iDisplayIndex) {// 当创建了行，但还未绘制到屏幕上的时候调用，通常用于改变行的class风格，此处用于显示‘表格序号’ $('td:eq(0)', nRow).html(iDisplayIndex+1); return nRow; } */ });提示acceptId找不到，解决方案:
{ "mData":"acceptId", "mRender":function(data,type,full){ if(data !=null){ if(full.acceptUser !=null){ return full.acceptUser.userName; } }else{ return ""; } } }在写mRender时，必须所有路径都要有返回值，做了空值判断，但是没有给返回值所以出现了上述错误，做个记录，以备后续使用。
