Browser-based user interface and control architecture with priority attributes
A browser-enabled device includes a browser-based user interface and control architecture, which has a browser core, a browser framework, and a user interface. The user interface is written using a markup language. In processing event registrations, the browser framework receives an event registration. The received event registration having a response unique resource identifier (URI) content and a priority field. The priority field of the received event registration is examined to determine priority of the received event registration. If the browser core is loading the response URI content of a prior event registration and if the priority of the received event registration is higher than the priority of the prior event registration, then the loading of the response URI content of the prior event registration is halted, and loading of the response URI content of the received event registration is begun.

A computer-enabled method of processing event registrations in a browser-based user interface and control architecture of a browser-enabled device, the browser-based user interface and control architecture having a browser core, a browser framework, and a user interface, the user interface being written using a markup language, the method comprising:
receiving an event registration, by one or more processors, the received event registration having a response unique resource identifier (URI) content and a priority field, the event registration being received by the browser framework;
examining, by the one or more processors, the priority field of the received event registration to determine priority of the received event registration;
if the browser core is loading the response URI content of a prior event registration, then determining if the priority of the received event registration is higher than the priority of the prior event registration; and
if the priority of the received event registration is higher than the priority of the prior event registration, then:
halting the loading of the response URI content of the prior event registration and starting to load the response URI content of the received event registration, and
after starting to load the response URI content of the received event registration, returning to loading the response URI content of the prior event registration,
wherein the response URI content of the received event registration includes at least a portion of the user interface.
2. The method of claim 1 , further comprising:
if the priority of the received event registration is not higher than the priority of the prior event registration, then continuing to load the response URI content of the prior event registration.

alternating between loading the response URI contents of the received and prior event registrations until the second web page has been completely loaded; and
when the second web page has been completely loaded, instructing the display of the second web page on the browser-enabled device.
12. The method of claim 1 , wherein the prior event registration is related to a first web page, wherein the received event registration is related to a second web page, and further comprising:
when the first web page has been loaded and is being displayed on the browser-enabled device, loading the response URI content of the received event registration in background on the browser core; and
when the second web page has been completely loaded, instructing the browser-enabled device to switch from displaying the first web page to displaying the second web page.
13. A non-transitory computer-readable storage medium having computer-executable instructions for processing event registrations in a browser-based user interface and control architecture of a browser-enabled device, the browser-based user interface and control architecture having a browser core, a browser framework, and a user interface, the user interface being written using a markup language, comprising instructions for:
receiving an event registration, the received event registration having a response unique resource identifier (URI) content and a priority field, the event registration being received by the browser framework;
examining the priority field of the received event registration to determine priority of the received event registration;
if the browser core is loading the response URI content of a prior event registration, then determining if the priority of the received event registration is higher than the priority of the prior event registration; and
if the priority of the received event registration is higher than the priority of the prior event registration, then:
halting the loading of the response URI content of the prior event registration and starting to load the response URI content of the received event registration, and
after starting to load the response URI content of the received event registration, returning to loading the response URI content of the prior event registration,
wherein the response URI content of the received event registration includes at least a portion of the user interface.
14. The computer-readable storage medium of claim 13 , further comprising instructions for:
if the priority of the received event registration is not higher than the priority of the prior event registration, then continuing to load the response URI content of the prior event registration.
