我有一个带有复选框列的剑道网格。当相应的复选框被选中时,我一直在尝试获取数据项行。单击按钮时,我只需要在 JSon 中获取选中的行。这是一个 JSfiddle 我一直在玩。它只获取 Id 而不是行数据。我一直在尝试修改,以便它可以返回整个行数据。

        var crudServiceBaseUrl = "http://demos.kendoui.com/service",
            dataSource = new kendo.data.DataSource({
                transport: {

        //bind click event to the checkbox
        grid.table.on("change", ".checkbox" , selectRow);

        $("#showSelection").bind("click", function () {
            var items = [];
            for(var i in checkedrows){
                if(checkedrows[i]){
                    items.push([i]);
                }
            }

            alert(JSON.stringify(itemss));
        });
    });

    var checkedrows = {};
    var itemss =[];
    //on click of the checkbox:
    function selectRow() {
        var checked = this.checked,
            row = $(this).closest("tr"),
            grid = $("#grid").data("kendoGrid"),
            dItem = grid.dataItem(row);

        checkedrows[dItem.id] = checked;
        if (checked) {
            itemss.push(dItem)
            //-select the row


        } 
        else
        {
            itemss.pop(dataItem);
        }
    }

数据项可以访问行获取,但是如何根据索引获取数据项。谢谢。

为了得到复选框,我用这个

var grid = $("#Grid").data("kendoGrid");

        grid.tbody.find("input:checked").closest("tr").each(function (index) {
            whatever you need done.
        });

2014 年接受的答案是正确的,但现在 api 已经改进。您可以使用以下代码段来获取数据项。请注意,选中的行也将被选中,因此会从 grid.select() 调用中返回。

//get the grid
var grid = $("#grid").data("kendoGrid");

// array to store the dataItems
var selected = [];

//get all selected rows (those which have the checkbox checked)  
grid.select().each(function(){

    //push the dataItem into the array
    selected.push(grid.dataItem(this));

});

您可以通过 存储所选项目uid,然后在需要时从数据源中获取它们。

选择处理程序:

function selectRow() {
    var checked = this.checked,
        row = $(this).closest("tr"),
        grid = $("#grid").data("kendoGrid"),
        dataItem = grid.dataItem(row);

    checkedrows[dataItem.uid] = checked;
}

要获取项目的序列化数组:

function getSerializedSelectedRows() {
    var items = [],
        item,
        grid = $("#grid").data("kendoGrid");

    for (var uid in checkedrows) {
        if (checkedrows.hasOwnProperty(uid)) {
            if (checkedrows[uid]) {
                item = grid.dataSource.getByUid(uid);
                items.push(item);
            }
        }
    }

    return JSON.stringify(items);
}

你可以检查这个

var gridData2 = $("#CustomerAccountManagerKendoGrid2").data("kendoGrid").dataSource.data();  

var gEmpID2 = GetSelectedEmpID(gridData2); 


function GetSelectedEmpID(gridData) {  
     for (var i = 0; i < gridData.length; i++) {  
       if (gridData[i].SelectStatus == true) {  
         return gridData[i].GEmployeeGenInfoID;  
       }  
     }  
   }
