Embedded Interface- Records

As far as I know, to embed a record dashboard on HTML5 page, we use custom tags. Appian then generates the UI for it when the page is rendered..So your web page can be a mix of HTML5 content(UI widgets like div, input etc) and the UI widgets generated by SAIL (embedded).. Appian generates the DOM for the embedded record dashboard. So, it should be possible to attach events even to the DOM generated by Appians embedded SAIL.

Now, open the chrome Dev console and inspect the button which is there in the record dashboard. That button should have attributes like class, id etc. You could make use of those and write event handlers in JS for them. But, I see a problem - do those attributes change everytime the embedded form is rendered? Does the ID or class of that button change everytime? If yes, then it will be tricky. If no, then you can easily write a event handler for it, and attach the event handler after the page loads(you could put the JS script after the custom tag used).

One more thing - as you mentioned the page can navigate away on click of the button. So, is your requirement something like this : the page can navigate when the button is clicked (or something else may happen depending on the SAIL interface/logic in that record dashboard), and in parallel you also want to trigger something else ? Is it something like this that you are looking for? This can still be done, but will be tricky.

Chetan- I just need to inform my html5 page on click of a button on record dashboard. Everything else can be then maintained by html5 page.
Yes- The class or id change and their tags are not even constant for all releases.
