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:

    **示例代码请点击展开** 
    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',
                                btnText: '确定'
                            });
                        }
                    });
                },
                //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。
