grid

參考示例：右鍵菜單

            
          

一：創(chuàng)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">編輯節(jié)點(diǎn)</li>
    <li name="remove" iconCls="icon-remove" onclick="onRemove">刪除節(jié)點(diǎn)</li>        
</ul>

           

二：設(shè)置表格contextmenu

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

           

三：監(jiān)聽beforeopen事件          

監(jiān)聽右鍵菜單的beforeopen事件，可以對(duì)右鍵菜單精確控制。

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;
        //阻止瀏覽器默認(rèn)右鍵菜單
        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：表頭菜單headerContextMenu

 創(chuàng)建同樣一個(gè)menu菜單對(duì)象，設(shè)置給表格的headerContextMenu屬性即可。
