grid

參考示例：樹(shù)右鍵菜單

      

           

一：創(chuàng)建ContextMenu     

<ul id="treeMenu" class="mini-contextmenu"  onbeforeopen="onBeforeOpen">        
    <li iconCls="icon-move" onclick="onMoveNode">移動(dòng)節(jié)點(diǎn)</li>
    <li class="separator"></li>
    <li>
        <span iconCls="icon-add">新增節(jié)點(diǎn)</span>
        <ul>
            <li onclick="onAddBefore">插入節(jié)點(diǎn)前</li>                
            <li onclick="onAddAfter">插入節(jié)點(diǎn)后</li>    
            <li onclick="onAddNode">插入子節(jié)點(diǎn)</li>                 
        </ul>
    </li>
    <li name="edit" iconCls="icon-edit" onclick="onEditNode">編輯節(jié)點(diǎn)</li>
    <li name="remove" iconCls="icon-remove" onclick="onRemoveNode">刪除節(jié)點(diǎn)</li>        
</ul>

           

二：設(shè)置contextmenu   

<ul id="tree1" class="mini-tree" url="../data/tree.txt" style="width:200px;padding:5px;" 
    showTreeIcon="true" textField="text" idField="id" 
    contextMenu="#treeMenu">        
</ul>

          

三：監(jiān)聽(tīng)beforeopen事件   

function onBeforeOpen(e) {
    var menu = e.sender;
    var tree = mini.get("tree1");

    var node = tree.getSelectedNode();
    if (!node) {
        e.cancel = true;
    }
    if (node && node.text == "Base") {
        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 (node.id == "forms") {
        editItem.hide();
    }
    if (node.id == "lists") {
        removeItem.disable();
    }
}
