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

javascript 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": "" } };

  1. 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',
    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();

  2. 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。
