Javascript 页面在清除主干视图数组时被挂起

我正在通过以下代码清除主干阵列，但我看到在执行this.views=[]时浏览器被挂起

resetView : function(){
    this.views = [];
},

有没有人遇到过类似的问题。在某些情况下，浏览器会在几分钟后继续运行，但在大多数情况下，我会收到一个无响应的脚本警报框

这是我的全部代码

initbrands: function(){
    if(!app.views.brands)
        app.views.brands = new app.View.TabContainer({
            collection: new app.Collection.TabBrand(),
            ViewModel: app.View.Brand,
            MenuTemplate: _.template($('#brands-menu').html()),
            TabHeaderTemplate : _.template($('#brands-header').html())
        });
    return app.views.brands;
},

initAddBrand: function(listView){
    if(!app.views.addbrand){
        app.views.addbrand = new app.View.AddBrand();
        app.views.addbrand.bind('successBrands', listView.collection.fetch, listView.collection);

    return app.views.addbrand;

    this.selectMenu('brands');

    view.collection.owned();

    var addview = this.initAddBrand(view);

    addview.collection = view.collection;

    if(this.views.indexOf(view)===-1){
        this.resetView();

你确定

这个
就是你所想的吗？为什么你认为这一行是问题所在？是的，因为我使用firebug进行了调试，当涉及到这一行时，它会挂起。我在下一行中设置了一个断点，其余的执行工作正常，
这就是您所期望的？
resetView
是如何调用的？是的，我确定。。我还交叉检查了它并看到了这个。视图在数组中包含两个元素。您检查过内存泄漏或类似的情况吗？重置该阵列可能会触发其他问题，而不是真正的问题。
