window.name is not persistent in Google Chrome

Question

I'm seeing a strange behavior in Google Chrome, using the window.name property.

For example:

1. open a tab and go to http://google.com .

2. Open up console, and type window.name="hello".

3. Now in the same tab, go to http://chase.com.

4. In the console, type window.name.

I expect to see "hello" returned, but instead I see "".

Is this a known issue for Google Chrome? It works for me in FireFox.

Anyone have any insight to this behavior?

Thanks!

Update:

If, instead of typing in a new URL, I type window.location="http://chase.com", then the window.name persists!

Answer 1

window is a global object for each document, not for the browser window. In a page with iframes you will have one window for each iframe for example. Each time a document is loaded, a new global object is created and populated for the context. When the document is unloaded, the global object along with all its data is destroyed.
