将属性添加到复选框后退网格

Question

大家好，我正在使用后网格来渲染我的表格，碰巧也有一些复选框。现在我想向这些复选框添加 2 个属性，但我不知道该怎么做。有人可以告诉我如何完成它。谢谢

.HTML

<div id="dayResult" class="backgrid-container" style="width: 139PX; height: initial; "></div>

.JS

var grid1 = new Backgrid.Grid({
  columns: [ {
    name: "name",
    label: "",
    cell: "string"
  },{
    // name is a required parameter, but you don't really want one on a select all column
    name: " ",
    // Backgrid.Extension.SelectRowCell lets you select individual rows
    cell: "select-row",
    // Backgrid.Extension.SelectAllHeaderCell lets you select all the row on a page
    // headerCell: "select-all",
  }],
  collection: new Backbone.Collection([
    {"name": "Monday"},
    {"name": "Tuesday"},
    {"name": "Wednesday"},
    {"name": "Thursday"},
    {"name": "Friday"},
    {"name": "Saturday"},
    {"name": "Sunday"}
  ])
});
$("#dayResult").append(grid1.render().el);

您需要

扩展复选框列单元格的render()方法。

我做了类似的事情来向我的复选框图像添加属性。我不使用"选择行"方法，但我相信您可以像这样扩展它：

   cell: Backgrid.Cell.extend({
    className: '4YearDegree',
    render: function() {
        var degree = this.model.get("Degree");
        var src = '';
        var altText = '';
        if (degree) {                
            src = '../Content/Images/enabled_checkmark.png'; //display enabled checkmark image 
            altText = 'is checked';
            } else {
            src = '../Content/Images/disabled_checkmark.png'; //display disabled checkmark image 
            altText = 'is unchecked';
            }
        this.$el.html($('<img>').attr('src', src).attr('alt', altText));
        return this;
        }
    })

上面代码的关键部分是这一行：

this.$el.html($('<img>').attr('src', src).attr('alt', altText));

我用它来将"altText"附加到我的复选标记图像中。

尝试以这种方式添加您自己的自定义属性。它可以/应该工作。
