How many Javascript objects does the HTML Toolkit support beyond window.alert()? It's the only one called out specifically in the Programmer Reference, so I'm not sure the full extent of browser support that I can expect within the tool kit. My biggest question right now is how much can I use XMLHttpRequest to make AJAX calls from the phone? We have a need where when the user presses a button, we need to hit an API endpoint of another machine to trigger a series of processes. Is there support for this object, or a similar object that could do the same thing? Am I allowed to load an external page to my phone - where I could process that request and redirect to a site inside the package? How do I best start integrating with external systems from my 53xx phones?
