代码如下：

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');

这样写会引起内存泄漏吗？哪些地方是不合理的？
