jQuery分离IE问题？

Question

For tab persistence in Backbone, I am saving the backbone view for that tab (say tab1) and detaching it from DOM. Later when the user comes back to the tab1 the saved view is rendered.

I am saving the page state ie the backbone view as -

this.pageState = $(this.bodyContainer.$el.find(".pageContent"));
$(this.bodyContainer.$el.find(".pageContent")).detach();

This works perfectly on ff and chrome but for IE I have to do the following work around for IE -

if($.browser.msie)
  this.pageState = $(this.bodyContainer.$el.find(".pageContent")).clone();
else
  this.pageState = $(this.bodyContainer.$el.find(".pageContent"));

$(this.bodyContainer.$el.find(".pageContent")).detach();

Is there a jQuery detach issue for IE? Is there a better way to copy view that works for all browsers?

Answer 1

I am not sure if this is awesome or not:

var pageStateElem = $(this.bodyContainer.$el.find(".pageContent"));

this.pageState = $.browser.msie ? pageStateElem.clone() : pageStateElem;

pageStateElem.detach();

I only removed some of the repetition from your code. :-p
