Question

I want to choose a specific window, and perform operations on that window- I will pass that window as a parameter to another function which does the work…

I know beforehand, that the title of the windows is (for example) “XYZ”

How do I select the window in browser with that title?

I found that in javascript there are ways to assign a title to a window, but I couldnt find a way to search for and find the window which has a specific title.

Answer 1

You cannot select other windows, unless you’ve already got a reference to it.

There are two methods to get a reference:

• The window.opener property holds a reference to the window which opened the current one.
• Saving the return value of window.open() also offers a reference.

Each reference to another window will be a window object. window.document.title can be used to read the value of the title. (where window is the reference to the other window).

Cross-domain restrictions will prevent other windows from being read, though.

See this answer to read the document/window object of embedded frames.
