改动

在 ActivateRoutes.prototype.activateRoutes添加了

ActivateRoutes.prototype.activateRoutes = function (futureNode, currNode, parentContexts) {
        var future = futureNode.value;
        var curr = currNode ? currNode.value : null;
        advanceActivatedRoute(future);
        // reusing the node
        if (future === curr) {
            if (future.component) {
                // If we have a normal route, we need to go through an outlet.
                var context = parentContexts.getOrCreateContext(future.outlet);
                this.activateChildRoutes(futureNode, currNode, context.children);
            }
            else {
                // if we have a componentless route, we recurse but keep the same outlet map.
                this.activateChildRoutes(futureNode, currNode, parentContexts);
            }
        }
        else {
            if (future.component) {
                // if we have a normal route, we need to place the component into the outlet and recurse.
                var context = parentContexts.getOrCreateContext(future.outlet);
                if (this.routeReuseStrategy.shouldAttach(future.snapshot)) {
                    var stored = this.routeReuseStrategy.retrieve(future.snapshot);
                    this.routeReuseStrategy.store(future.snapshot, null);
                    context.children.onOutletReAttached(stored.contexts);
