YouTube Music Video External Javascript Genericization Tutorial

YouTube Music Video External Javascript Genericization Tutorial

In yesterday’s The Wrecking Crew Peering Disco Tutorial we praised the role of external Javascript in the current YouTube Music Video Peer to Peer web applications …

• more twinning possibilities, easily applied, as per today’s Stop Press
• generic YouTube IFrame Player API based music web application changes

… and it is that second more involved advantage we want to chase down today, and into the future.

Today, we’ve made our first only to external Javascript generic changes, which flow through to the three parent web applications by …

• honing in on top textbox …
• improving its placeholder information … thereby …
• informing the user that a right click (or two finger gesture) will lead to a list of comma separated YouTube video IDs,Title (our first cab off the rank being title “Mr Smith Goes To Washington”) being mapped onto the textbox’s value … then …
• [textboxObject].blur(); (ie. the onblur event logic is called)
