Automatically recovering and maintaining focus

A system comprising:

• one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• setting focus on, and receiving a selection of, a particular interactive element on a web page;
• storing data indicating that focus was set on the particular element on the web page, in a navigation history;
• in response to receiving the selection of the particular interactive element on the web page, providing, for display, a dialog box;
• setting focus on, and receiving a selection of, a particular interactive element of the dialog box that causes the dialog box to be removed from display;
• receiving a request to change focus from one element to another
• identifying one or more interactive elements of the web page on which focus be set;
• determining that, when the request to change focus from one element to another was received, focus was set on the particular interactive element of a dialog box that was provided for display in response to receiving the selection of a particular interactive element on the web page, that the particular interactive element of the dialog box is not identified among the one or more active interface elements of the web page;
• and
• in response to determining that focus was set on the element of the dialog box, identifying, in the navigation history, the particular interactive element on the web page as a latest interactive element to have focus before the dialog box was provided for display, and, in response, setting focus on the particular interactive element of the web page.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• setting focus on, and receiving a selection of, a particular interactive element on a web page;
• storing data indicating that focus was set on the particular element on the web page, in a navigation history;
• in response to receiving the selection of the particular interactive element on the web page, providing, for display, a dialog box;
• setting focus on, and receiving a selection of, a particular interactive element of the dialog box that causes the dialog box to be removed from display;
• receiving a request to change focus from one element to another
• identifying one or more interactive elements of the web page on which focus be set;
• determining that, when the request to change focus from one element to another was received, focus was set on the particular interactive element of a dialog box that was provided for display in response to receiving the selection of a particular interactive element on the web page, that the particular interactive element of the dialog box is not identified among the one or more active interface elements of the web page;
• and
• in response to determining that focus was set on the element of the dialog box, identifying, in the navigation history, the particular interactive element on the web page as a latest interactive element to have focus before the dialog box was provided for display, and, in response, setting focus on the particular interactive element of the web page.
