angularjs 功能雖然非常強大,但ui上提供的插件不像jquery那麼多,而且隻能通過directive定義擴充的ui插件,雖然國外已經提供了一些基于 directive的tree功能實作,但畢竟不像ztree那樣強大,而且tree是做項目中很長用的一個基本功能。
是以,花了一點時間做了一個例子将ztree應用到angularjs中。

$.fn.ztree.init(element, setting, znodes);
}
};
});
appmodule.controller('mycontroller', function ($scope) {
實作功能:定義tree這個屬性,使<ul tree class="ztree" ng-model="selectnode"></ul>自動變成一個有資料的tree,點選樹節點,自動變更model 的selectnode。
