代碼如下：document.onload = (function() {    var GraphCreator = function(name) {        var thisGraph = this;        console.log(thisGraph);        this.name = name || '';    };    GraphCreator.prototype.setName = function(name) {        var thisGraph = this;        thisGraph.name = name;    };    GraphCreator.prototype.addTab = function(data) {        var content = document.getElementById('content');        var tab = juicer($('#extended_tpl').html(), data);        content.append(tab);    };    window.GraphCreator = GraphCreator;})();var graph = new GraphCreator();graph.setName('graph_one');這樣寫會(huì)引起內(nèi)存泄漏嗎？哪些地方是不合理的？
