Question

在javascript和/或jquery中是否有一个示例，其中某人有一个“全部检查”复选框，用于检查网格所有页面中的所有复选框？

我现在已经尝试了3天，但我找不到干净的答案。

我现在拥有的是丑陋的，并没有真正起作用......

        function onRequestEnd(e) {
            var masterCbChecked = $("#masterCheckBox").is(':checked');
            var grid = $("#grid").data("kendoGrid");

            for (var i = 0; i < grid.dataSource.total(); i ++) {
                var dataRow = $("#grid").data("kendoGrid").dataSource.data()[i];
                var elementRow = grid.table.find(".cbAdvisor")[i];
                if (elementRow != null) {
                    var checked = elementRow.checked,
                        row = $(elementRow).closest("tr"),
                        dataItem = grid.dataItem(grid.tbody.find("tr").eq(i));
                    checkedIds[dataItem.DimAgentId] = masterCbChecked;

Answer 1

我通过一些修改得到了这个代码：

columns.Template(@<text><input name="chkStatus" type="checkbox" class="chkFormols" /></text>)
.HeaderTemplate("<input type='checkbox' id='chkSelectAll' onclick='checkAll(this)' />").Width(50);



function checkAll(ele) {
            debugger;
            var state = $(ele).is(':checked');
            var grid = $('#grid').data('kendoGrid');
            if (state == true) {
                $('.chkFormols').prop('checked', true);
            }
            else {

                $('.chkFormols').prop('checked', false);
            }
        };
