Backgrid无法呈现列

Question

我只是在学习backgrid.js的基础知识。因此，当我试图在主页面Backgrid.js上复制代码时，由于传递列的对象数组时出现特定错误，无法呈现网格。我相信我用的是正确的格式

 var columns = [
    { name: "name", label: "Name", cell: "string" },
    { name: "address", label: "Address", cell: "string" },
    { name: "tel", label: "Phone", cell: "integer" },
    { name: "email", label: "Email", cell: "string" },
    { name: "type", label: "Contact Type", cell: "string" }
];

在此步骤初始化网格的过程中，TypeError: Object对象对象没有方法“listenTo”发生错误：

    var grid = new Backgrid.Grid({
        columns: columns,
        collection: this.collection
    });

我如何初始化网格有问题吗？

Answer 1

问题在于我使用的backbone.js版本。我再次推荐使用适当版本的库。

Backgrid.js依赖于3个库来运行： JQuery1.7.0、>= ~ 1.4.0和backbone.js ~ 0.9.10。

这是一个关于如何使用它的简单结构。

HTML

<div id="container"></div>

JS

$(function(){
    /** Columns definition */
    var columns = [
    { name: "name", label: "Name", cell: "string" },
    { name: "address", label: "Address", cell: "string" },
    { name: "tel", label: "Phone", cell: "integer" },
    { name: "email", label: "Email", cell: "string" },
    { name: "type", label: "Contact Type", cell: "string" }
    ];

    /** Model instance */
    var mdl = Backbone.Model.extend({});

    /** Collection instance */
    var col = Backbone.Collection.extend({
        model: mdl  
    });

    /** Test array of JSON (usually coming from a server) */
    var json = [
        {"name": "Goose", "address": "a 1st address", "tel": 25500100, "email": "w@test.net","type": 1},
        {"name": "Ducky", "address": "a 2nd address", "tel": 25500123, "email": "w@test1.net","type": 2}
   ];

   /** Create the Grid */
   var grid = new Backgrid.Grid({
      columns: columns,
      collection: new col(json)
   });

   /** Add the Grid to the container */
   $("#container").append(grid.render().$el);
});
