为所有页面设置dijit.tree cookie

似乎 Tree.js 不允许您设置cookie的属性。所以我不得不重写 _saveState() 方法 Tree :

var treeControl = new dijit.Tree({
    model: treeModel,
    showRoot: false,
    openOnClick: false,
    cookieName: "OrganizationUnitTreeState",
    _saveState: function(){
        // summary:
        // Create and save a cookie with the currently expanded nodes identifiers
        // Overre the default saveState function, so we can set the cookie path
        if(!this.persist){
            return;
        }
        var ary = [];
        for(var id in this._openedItemIds){
            ary.push(id);
        }
        dojo.cookie(this.cookieName, ary.join(","), {expires:365, path:"/"});
    },
    /* Many more methods */
});

这是最后一行代码。这个 dojo.cookie() 获取键/值对的列表,这些键/值对将转换为cookie属性,因此如果您希望设置任何其他属性,请执行以下操作。
