jQuery MiniUI 开发教程 CRUD之:单元格编辑(一)


参考示例:单元格编辑


一:创建单元格编辑器
<div id="datagrid1" class="mini-datagrid" style="width:800px;height:280px;"
    url="../data/AjaxService.aspx?method=SearchEmployees" idField="id"
    allowResize="true" pageSize="20"
    allowCellEdit="true" allowCellSelect="true" multiSelect="true">
    <div property="columns">
        <div type="checkcolumn"></div>           
        <div field="loginname" width="120" headerAlign="center" allowSort="true">员工帐号
            <input property="editor" class="mini-textbox" style="width:100%;"/>
        </div>               
        <div field="gender" width="100" renderer="onGenderRenderer" align="center" headerAlign="center">性别
            <input property="editor" class="mini-combobox" style="width:100%;" data="Genders"/>               
        </div>
        <div field="age" width="100" allowSort="true" >年龄
            <input property="editor" class="mini-spinner" minValue="0" maxValue="200" value="25" style="width:100%;"/>
        </div>
        <div field="birthday" width="100" allowSort="true" dateFormat="yyyy-MM-dd">出生日期
            <input property="editor" class="mini-datepicker" style="width:100%;"/>
        </div>   
        <div field="remarks" width="120" headerAlign="center" allowSort="true">备注
            <input property="editor" class="mini-textarea" style="width:100%;" minHeight="80"/>
        </div>                                
        <div field="createtime" width="100" headerAlign="center" dateFormat="yyyy-MM-dd" allowSort="true">创建日期</div>
    </div>
</div>
设置allowCellEdit和allowCellSelect后,表格为单元格编辑模式。           
二:编辑操作         

增加行:

function addRow() {
    var newRow = { name: "New Row" };
    grid.addRow(newRow, 0);
}
删除行:
function removeRow() {
     var rows = grid.getSelecteds();    
     if (rows.length > 0) {
          grid.removeRows(rows, true);    
     }
}          
保存数据:

function saveData() {
    //获得增加、删除、修改的记录集合
    var data = grid.getChanges();
    var json = mini.encode(data);
    grid.loading("保存中,请稍后......");       
    $.ajax({
        url: "../data/AjaxService.aspx?method=SaveChangedEmployees",
        data: { data: json },
        type: "post",
        success: function (text) {
            grid.reload();
        },
        error: function (jqXHR, textStatus, errorThrown) {
            alert(jqXHR.responseText);
        }
    });
}
         
三:服务端处理

public void SaveChangedEmployees()
{
    String json = Request["data"];
    ArrayList rows = (ArrayList)PluSoft.Utils.JSON.Decode(json);

    foreach (Hashtable row in rows)
    {
        //根据记录状态,进行不同的增加、删除、修改操作
        String state = row["_state"] != null ? row["_state"].ToString() : "";
        if(state == "added")
        {
            row["createtime"] = DateTime.Now;
            new TestDB().InsertEmployee(row);
        }
        else if (state == "removed" || state == "deleted")
        {
            String id = row["id"].ToString();
            new TestDB().DeleteEmployee(id);
        }
        else if (state == "modified")
        {
            new TestDB().UpdateEmployee(row);
        }
    }
}
