grid

参考示例：右键菜单

            
          

一：创建ContextMenu

<ul id="gridMenu" class="mini-contextmenu" onbeforeopen="onBeforeOpen">              
    <li name="add" iconCls="icon-add" onclick="onAdd">新增</li>
    <li name="edit" iconCls="icon-edit" onclick="onEdit">编辑节点</li>
    <li name="remove" iconCls="icon-remove" onclick="onRemove">删除节点</li>        
</ul>

           

二：设置表格contextmenu

<div id="datagrid1" class="mini-datagrid" 
    contextMenu="#gridMenu">
    ......
</div>   

           

三：监听beforeopen事件          

监听右键菜单的beforeopen事件，可以对右键菜单精确控制。

function onBeforeOpen(e) {
    var grid = mini.get("datagrid1");
    var menu = e.sender;
            
    var row = grid.getSelected();
    var rowIndex = grid.indexOf(row);            
    if (!row ||  rowIndex== 0) {
        e.cancel = true;
        //阻止浏览器默认右键菜单
        e.htmlEvent.preventDefault();
        return;
    }
    ////////////////////////////////
    var editItem = mini.getbyName("edit", menu);
    var removeItem = mini.getbyName("remove", menu);
    editItem.show();
    removeItem.enable();

    if (rowIndex == 1) {
        editItem.hide();
    }
    if (rowIndex == 1) {
        removeItem.disable();
    }

}

           

四：表头菜单headerContextMenu

 创建同样一个menu菜单对象，设置给表格的headerContextMenu属性即可。
