datagrid在MVC中的运用10-勾选

本文体验与勾选有关的特性。

需要加载的books.json

展开{
  "total": 4,
  "rows": [
    {
      "productid": "FI-SW-01",
      "productname": "Koi",
      "unitcost": 10.00,
      "status": "P",
      "listprice": 36.50,
      "attr1": "Large",
      "itemid": "EST-1",
      "checked": true
    },
    {
      "productid": "K9-DL-01",
      "productname": "Dalmation",
      "unitcost": 12.00,
      "status": "P",
      "listprice": 18.50,
      "attr1": "Spotted Adult Female",
      "itemid": "EST-10",
      "checked": true
    },
    {
      "productid": "RP-SN-01",
      "productname": "Rattlesnake",
      "unitcost": 12.00,
      "status": "P",
      "listprice": 38.50,
      "attr1": "Venomless",
      "itemid": "EST-11",
      "checked": true
    },
    {
      "productid": "RP-SN-01",
      "productname": "Rattlesnake",
      "unitcost": 12.00,
      "status": "P",
      "listprice": 26.50,
      "attr1": "Rattleless",
      "itemid": "EST-12",
      "checked": false
    }
  ]
}

视图

展开@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<link href="~/Content/themes/default/easyui.css" rel="stylesheet" />
<link href="~/Content/themes/icon.css" rel="stylesheet" />

<input type="button" id="ButtonGetCheck" value="Get Checked"/>
<table id="tt"></table>

@section scripts
{
    <script src="~/Scripts/jquery.easyui.min.js"></script>
    <script src="~/Scripts/easyui-lang-zh_CN.js"></script>
    <script type="text/javascript">
        $(function() {
            initData();
        });

        function initData() {
            $('#tt').datagrid({
                title: 'Checkbox selection on DataGrid',
                url: 'books.json',
                method: 'get', //默认是post,不允许对静态文件访问
                width: '700',
                rownumbers: true,
                columns: [[
                    { field: 'ck', checkbox: true },
                    { field: 'productid', title: 'productid' },
                    { field: 'productname', title: 'productname' },
                    { field: 'unitcost', title: 'unitcost' },
                    { field: 'status', title: 'status' },
                    { field: 'listprice', title: 'listprice' },
                    {field: 'itemid', title: 'itemid'}
                ]],
                singleSelect: false, //允许选择多行
                selectOnCheck: true,//true勾选会选择行，false勾选不选择行, 1.3以后有此选项
                checkOnSelect: true //true选择行勾选，false选择行不勾选, 1.3以后有此选项
            });
        }
    </script>
}

注意：
如果没有设置 method: 'get'，就会报错，因为默认不能以post方式访问静态文件books.json。

效果：

以上没有把books.json中"checked": true的行设置为选中。

设置每行属性checked为true的行选中

                onLoadSuccess: function(data) {

                    if (data) {

                        $.each(data.rows, function(index, item) {

                            if (item.checked) {

                                $('#tt').datagrid('checkRow', index);

                            }

                        });

                    }

                }

效果：

获取选中行的值

        $(function() {

            initData();

            $('#ButtonGetCheck').click(function() {

                var checkedItems = $('#tt').datagrid('getChecked');

                var names = [];

                $.each(checkedItems, function(index, item) {

                    names.push(item.productname);

                });

                console.log(names.join(","));

            });

        });

font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}

/Customer/Index 视图

展开$('#tt').datagrid({
                url: '@Url.Action("GetData","Customer")',
                width: 730,
                height: 400,
                title: 'Customer列表',
                fitColumns: true,
                rownumbers: true, //是否加行号
                pagination: true, //是否显式分页
                pageSize: 15, //页容量，必须和pageList对应起来，否则会报错
                pageNumber: 2, //默认显示第几页
                pageList: [15, 30, 45],//分页中下拉选项的数值
                columns: [[
                    //CustomerID,CompanyName,ContactName,ContactTitle,Country,Region,Address,Fax,Phone,City
                    {field: 'ck', checkbox: true},
                    { field: 'CustomerID', title: '编号',sortable: true },
                    { field: 'CompanyName', title: '客户名称', sortable: true },
                    { field: 'ContactName', title: '联系人名称', sortable: true },
                    { field: 'ContactTitle', title: '职位', sortable: true },
                    { field: 'Address', title: '地址', sortable: true },
                    { field: 'City', title: '城市名称', sortable: true },
                    { field: 'Region', title: '区域' },
                    { field: 'Country', title: '国家' },
                    { field: 'Phone', title: '电话', sortable: true },
                    { field: 'Fax', title: '传真', sortable: true }
                ]],
                queryParams: params, //搜索json对象
                sortName: 'CustomerID', //初始排序字段
                sortOrder: 'asc' //初始排序方式
            });

效果：

可见，默认状态下：
可以多选
勾选会选择行
选中行会勾选
