javascript - 如何在 sencha 的网格中添加页脚

Question

这是我作为 PurchaseReport.js 的 View 部分

Ext.define("App.view.tabs.PurchaseReport", {
extend: "Ext.panel.Panel",
alias: "widget.PurchaseReportTab",
requires: [
        "App.model.PurchaseReport", "Ext.toolbar.Toolbar"
],
border: false,
layout: "fit",
items: [
    App.Util.buildBrowseConfig({}, {
        controller: "PurchaseReport",
        primaryKeyField: "PurchaseReportId",
        stateful: true,
        stateId: "App.view.windows.PurchaseReport-grid",

        columns: [
          { dataIndex: "PurchaseCost", filter: true, header: "Purchase Cost", width: 150 }
        ],
        features: [{ ftype: "filters", autoReload: false, local: true }],
        store: { model: "App.model.PurchaseReport", sorters: [{ property: "Name", direction: "asc" }] }
    })
]

});

这是我的 Controller 部分，我的网格在其中绑定(bind)为 PurchaseReport.js， 那么我需要在这里进行更改吗？

Ext.define("App.controller.tabs.PurchaseReport", {
extend: "Ext.ux.app.BrowseController",
views: ["tabs.PurchaseReport"],
refs: [
    {
        ref: "myPurchaseReportGrid",
        selector: "PurchaseReportTab > gridpanel"
    }
],

init: function () {
    this.control({
        PurchaseReportTab: {
            bind: function (a, c) {
             **//Grid bind start**
                var b = this.getMyPurchaseReportGrid();
                b.getSelectionModel().deselectAll();
                b.store.removeAll();
                b.fireEvent("bind", b, c)
                **//Grid bind End**

             **//Combobox Bind start**
                var combo = this.getCoachCombo(),
                      store = combo.store,
                      options = store.lastOptions || {};
                options = Ext.apply({
                    callback: function () {
                        combo.select(App.coach.CoachId)
                        //console.log("called rajesh");
                    }
                }, options);
                store.load(options);
                if (App.coach.IsAdmin) {
                    combo.show()
                }
                **//Combobox Bind end**


                var abilities = App.coach.Abilities,
                      toolbar = this.getToolbar();
                for (var x = 0; x < abilities.length; x++) {

                    var ability = abilities[x],
                        button = toolbar.query("button[tooltip=" + ability.Name + "]");
                    if (button.length) {
                        button[0].setVisible(true)
                    }
                }

            }
        },

        "PurchaseReportTab > gridpanel": {
            bind: this.bind,
            itemdblclick: this.handleRecord,
            selectionchange: this.selectionChange
        }


    })
}

});

这是我的模型部件名称 PurchaseReport.js

 Ext.define("App.model.PurchaseReport", {
extend: "Ext.data.Model",
fields: [
    {
        name: "PurchaseDate",
        type: "date"
    }
],

proxy: {
    type: "ajax",
    url: "ControllerFactory.aspx",
    extraParams: {
        controller: "PurchaseReport",
        operation: "GetPurchaseReportsByCoachIdAndDates"
    },
    reader: {
        type: "json",
        root: "data",
        successProperty: "success"
    }
}

});

但是我能够在 GridView 中显示记录，但我需要一个页脚区域，我可以在其中显示采购成本总额。在网格的底部

请不要发现代码错误，因为我删除了很多东西以使其看起来更简单，因为我是新手，请告诉我需要哪些更多细节。

只是一个图像更多细节

我已经尝试添加代码，但它在 Gridview 显示记录的所有页面中显示页脚，我只想在一个页面而不是其他页面上显示页脚，并且还需要显示总购买成本那个

Ext.define("Ext.grid.Panel", {
extend: "Ext.panel.Table",
requires: ["Ext.grid.View"],
alias: ["widget.gridpanel", "widget.grid"],
alternateClassName: ["Ext.list.ListView", "Ext.ListView", "Ext.grid.GridPanel"],
viewType: "gridview",
lockable: false,
bothCfgCopy: ["invalidateScrollerOnRefresh", "hideHeaders", "enableColumnHide", "enableColumnMove", "enableColumnResize", "sortableColumns"],
normalCfgCopy: ["verticalScroller", "verticalScrollDock", "verticalScrollerType", "scroll"],
lockedCfgCopy: [],
rowLines: true,
  //Newly addded start
 height: 200,
 width: 400,

 bbar: [
        {
        xtype: 'textfield',
        name: 'Total',
        fieldLabel: 'Total',
        allowBlank: false 
        }
            ],
renderTo: Ext.getBody()
 //Newly addded end
  });

Answer 1

要放置页脚，您需要在代码中使用 bbar。在您定义网格及其配置的代码中，您需要编写

示例:

 bbar: [
        {
        xtype: 'textfield',
        name: 'Total',
        fieldLabel: 'Total',
        allowBlank: false 
        }
    ],

请阅读Documentation 为了更好地理解。 我还为你做了一个 fiddle ，这样你就可以关联你的项目和网格。 Fiddle
