step 3. 实现grid表格数据展示和分页

1. 添加grid表格ui：进入pages/cardtable/cardtable.html中加入grid表格相关代码到相应位置：

   <div class="list-panel" id="manager">
       <h2>系统管理</h2>
     	
      <!-- grid表格相关代码 begin -->
       <div class="main-container cartable-container">
           <div class="hr-table">
               <div u-meta='{"id":"gridcardtable","type":"grid","data":"dt1","columnWidth":"150px","multiSelect":true,"contentSelect":false,"contentFocus":false,"canSwap":false}'>
                   <div options='{"field":"code","title":"系统编码","dataType":"String","editType":"string"}'></div>
                   <div options='{"field":"name","title":"系统名称","dataType":"String","editType":"string"}'></div>
                   <div options='{"field":"gateway","title":"网关地址","dataType":"String","editType":"string"}'></div>
                   <div options='{"field":"radiodatacontroller","title":"需要授权","type":"u-checkbox","data":"dt1","editOptions":{"datasource":"radiodatacontroller"},"renderType":"comboRender"}'></div>
                   <div options='{"field":"radiodataassociate","title":"用户自关联","type":"u-checkbox","data":"dt1","editOptions":{"datasource":"radiodataassociate"},"renderType":"comboRender"}'></div>
                   <div options='{"field":"combodatamodel","title":"认证模式","dataType":"String","editType":"string","renderType":"comboRender","editOptions":{"datasource":"combodatamodel"}}'></div>
                   <div options='{"field":"operate","dataType":"String","title":"操作","renderType":"optFun","editable":false,"autoExpand":true}'></div>
               </div>
           </div>
         	<!-- 分页部分 -->
           <div id='pagination' class='pagination u-pagination pagination-sm'></div>
       </div>
     <!-- grid表格相关代码 end -->
   </div>
   

2. 在js中添加grid表格中每一列对应field的参数：进入pages/cardtable/cardtablemeta.js中，将下面代码直接拷贝到该文件中

   var metaCardTable={
   		meta: {
               //系统名称，和html中每一列的options参数中的field是一一对应
   		"name":{
   			type:'string',
   			required:true,
   			notipFlag: true,
   			hasSuccess: true,
   			nullMsg:'系统名称不能为空!'
   		},
   		"code":{
   			type:'string',
   			required:true,
   			notipFlag: true,
   			hasSuccess: true,
   			nullMsg:'系统编码不能为空!'
   		},
   		"radiodatacontroller":"",
   		"radiodataassociate":"",
   		"combodatamodel":"",
   		"gateway": "",
   		"operate": ""
   	}
   };
   

3. 然后将上面的js文件引入到pages/cardtable/cardtablemeta.js中，并且在init()中加入以下代码来实现html和数据的绑定:

   var listUrl = ctx + '/cardtable/list';
   var viewModel = {
               app: {},
               draw: 1,//当前页面index
               totlePage: 0,
               pageSize: 5,
               totleCount: 0,
     			//dt1对应的就是上面html中的u-meta的data中的dt1
               dt1: new u.DataTable(metaCardTable),
               radiodatacontroller: [{
                value: 'Y',
                name: '是'
               }, {
                value: 'N',
                name: '否'
               }],
               radiodataassociate: [{
                value: 'Y',
                name: '是'
              }, {
                value: 'N',
                name: '否'
              }],
              combodatamodel: [{
                name: '信任',
                value: 'Y'
              }, {
                name: '不信任',
                value: 'N'
              }],
               event: {
                   //清除datatable数据
                   clearDt: function(dt) {
                       dt.removeAllRows();
                       dt.clear();
                   },
                   // 卡片表数据读取
                   initCardTableList: function() {
                       var jsonData = {
                           pageIndex: viewModel.draw - 1,
                           pageSize: viewModel.pageSize,
                           sortField: "createtime",
                           sortDirection: "asc"
                       };
                       $.ajax({
                           type: 'get',
                           url: listUrl,
                           dataType: 'json',
                           data: jsonData,
                           contentType: 'application/json;charset=utf-8',
                           success: function(res) {
                               if (res) {
                                   if (res.success == 'success') {
                                       if (res.detailMsg.data) {
                                           if(jsonData.pageSize==5&&jsonData.pageIndex==1){
                                               res.detailMsg.data.content.splice(0,5);
                                           }else if(jsonData.pageSize==5){
                                               res.detailMsg.data.content.splice(5,3);
                                           }
                                           viewModel.totleCount = res.detailMsg.data.totalElements;
                                           viewModel.totlePage = res.detailMsg.data.totalPages;
                                         	//更新分页信息
                                           viewModel.event.comps.update({
                                               totalPages: viewModel.totlePage,
                                               pageSize: viewModel.pageSize,
                                               currentPage: viewModel.draw,
                                               totalCount: viewModel.totleCount
                                           });
                                           viewModel.dt1.removeAllRows();
                                           viewModel.dt1.clear();
                                           viewModel.dt1.setSimpleData(res.detailMsg.data.content, {
                                               unSelect: true
                                           });
                                       }
                                   } else {
                                       var msg = "";
                                       if (res.success == 'fail_global') {
                                           msg = res.message;
                                       } else {
                                           for (var key in res.detailMsg) {
                                               msg += res.detailMsg[key] + "<br/>";
                                           }
                                       }
                                       u.messageDialog({
                                           msg: msg,
                                           title: '请求错误',
                                           btnText: '确定'
                                       });
                                   }
                               } else {
                                   u.messageDialog({
                                       msg: '后台返回数据格式有误，请联系管理员',
                                       title: '数据错误',
                                       btnText: '确定'
                                   });
                               }
                           },
                           error: function(er) {
                               u.messageDialog({
                                   msg: '请求超时',
                                   title: '请求错误',

                               });
                           }
                       });
                   },
                   //分页相关
                   pageChange: function() {
                       viewModel.event.comps.on('pageChange', function(pageIndex) {
                           viewModel.draw = pageIndex + 1;
                           viewModel.event.initCardTableList();
                       });
                   },
                   sizeChange: function() {
                       viewModel.event.comps.on('sizeChange', function(arg) {
                           viewModel.pageSize = parseInt(arg);
                           viewModel.draw = 1;
                           viewModel.event.initCardTableList();
                       });
                   },
                   //页面初始化
                   pageInit: function() {
                       viewModel.app = u.createApp({
                           el: element,
                           model: viewModel
                       });
   					//找到分页的节点
                       var paginationDiv = $(element).find('#pagination')[0];
                     	//初始化分页页面，在获取到页面的具体的数据时候还会去更新分页信息
                       this.comps = new u.pagination({
                           el: paginationDiv,
                           jumppage: true
                       });
                       this.initCardTableList();
                       viewModel.event.pageChange();
                       viewModel.event.sizeChange();
                   }
               }
           }
           $(element).html(html);
           viewModel.event.pageInit();
   

4. 然后刷新页面，看到表格出现了！

   在此代码中，主要最重要的就是u-meta中的json字符串其中的参数，我这里控制的是不能点击，表头不支持拖动更改列顺序，其他功能可以参见文档

到这里，我们已经完成了前面的准备工作，后面我会开始写如何去实现实现grid数据新增

请期待下一篇。
