EasyUI datagrid

 隐藏DataGrid数据：$("#eGrid").parent().parent().parent().parent().hide();

datagrid的参数配置的方式

方式1：

var queryParams = $('#menulist').datagrid('options').queryParams;
queryParams.catalogid = catalogid;
queryParams.DomainID = node.id;
queryParams.pageNumber = pageNumber;
queryParams.pageSize = pageSize;

方式2：

 $('#menulist').datagrid('options').pageNumber = 1;
$('#menulist').datagrid('getPager').pagination({ pageNumber: 1 });
$('#menulist').datagrid('options').url = 'menuService.ashx?Method=GetMenus&DomainID=' + node.id;
$("#txtMenuID").val(node.id);//隐藏域内的内容
$("#menulist").datagrid('reload');

标准的datagrid代码

 var pNumber = 0;
        var pSize = 20;

        $('#list').datagrid({
            method: 'post',
            url: 'GT028_URLInforService.ashx?Method=GetGT028_URLInfor',
            fitColumns: true,
            nowrap: true,
            loadMsg: '正在加载数据...',

            pagination: true,
            pageSize: pSize, //每页显示的记录条数，默认为10
            pageNumber: 1, //默认的页码
            pageList: [200, 100, 50, 30, 20], //可以设置每页记录条数的列表
            columns: [[
                    { title: 'id', field: 'GC028_ID',  20, checkbox: true },
                    { title: '类别', field: 'GC028_TYPE',  100 },

                    { title: '创建时间', field: 'GC028_CJSJ',  100,
                        formatter: function (value, row, index) {
                            var t = "";
                            if (value) {
                                t = value.replace("T", " ");
                            }
                            return t;
                        }
                    },
                    { title: '创建人', field: 'GC028_CJR',  100 },
                    { title: '备注', field: 'GC028_BZ',  100}]],
            toolbar: '#tb', // id 为tb的Div 详细 查看前台页面HTML代码
            onBeforeLoad: function () {
                $(this).datagrid('rejectChanges');
            },
            onClickRow: function (rowIndex, rowData) {

            },
            onDblClickRow: function (rowIndex, rowData) {
                $(this).datagrid("unselectAll"); //取消所有选中的行
                $(this).datagrid("selectRow", rowIndex); //选中当前双击的行记录
                initTool.edit();
            }
        });

 Footer Rows in DataGrid

grid的属性： showFooter: true

{"total":28,"rows":[
    {"productid":"FI-SW-01","unitcost":10.00,"status":"P","listprice":36.50,"attr1":"Large","itemid":"EST-1"},

    {"unitcost":198.00,"listprice":604.00,"productid":"Total:"}
]}

 

 固定住某一行 不随着滚动条滚动

onLoadSuccess: function (data) {
    $(this).datagrid('freezeRow', 0); 
        
}

 也可以连续住前两行：$(this).datagrid('freezeRow',0).datagrid('freezeRow',1);

参考官方的例子：

单元格变色

{ title: '申请类型', field: 'PC004_TYPE',  100, rowspan: 2,
                    styler: function(value,row,index){
                        return 'background-color:#ffee00;color:red;';
                    },

                    formatter: function (value, row, index) {
                        var str = "";
                        switch (value) {
                            case "1":
                                str = "购买";

 easyUI datagrid扩展：

http://www.oschina.net/code/snippet_659525_20039

双击grid实现修改的操作

 onDblClickRow: function (rowIndex, rowData) {
                $("#list").datagrid("unselectAll");//取消所有的选中
                $("#list").datagrid("selectRow", rowIndex);//选中当前行
                me.edit();//弹窗修改
            },
