SharePoint Stack Exchange is a question and answer site for SharePoint enthusiasts. It's 100% free, no registration required.

This function is then used throughout the page for various reasons. Usually it appears as the first line in other java-script functions.

As an example:

function toggleBlockOn(elementID) {
      ULS18u:;
      if (document.getElementById(elementID).style.backgroundImage != "") {
      turnOnBlock(elementID);
      }
      }

The main interest here is the syntax of that first line. How does that work?
