Adding debugging code to the HTML

From: Set a Marquee to Autoplay with jQuery and Dreamweaver

Video: Adding debugging code to the HTML

In the introduction video when we looked at the marquee, I had shown one example of having a debugging area where we could actually see the timers, the number of panels, which panel we were currently on, and the state of the autoPlay. So what we're going to do is add some HTML outside of our marquee container where we can actually target and send variables that we set it up in JavaScript over to our HTML page, so we can sort of see what's going on as we are programming our autoplay. So what I'm going to do is outside of the marquee container, we're going to add a few more divs. So first thing I am going to type div, space, start to type cl, Dreamweaver's auto complete will come up, I'll hit Return. Class=.

So what I'm going to do is outside of the marquee container, we're going to add a few more divs. So first thing I am going to type div, space, start to type cl, Dreamweaver's auto complete will come up, I'll hit Return. Class=.

In the very first class we're going to create is autoPlay. Come outside of there, close the tag. So autoPlay is something that's not existing inside of our CSS, but we're going to use this to target inside of jQuery. Let's copy this entire div, Command+C or Ctrl+C, Command+V or Ctrl+V to paste. 2,3,4,5, make sure we have five divs in place. On the second one I'm simply going to double-click on the class and Dreamweaver will automatically select the entire class name.

We're going to type currentPanel with a capital P. On the second one we're going to type totalPanels, on the third one we're going to type timePassed, and on the fourth one we're to put in timeToChange. Now that we have these divs in place, what we're going to do in the next movie when we start our JavaScript file is every time we change the value inside the JavaScript, we're going to send that data over to the HTML page so that we can actually see it.

So as we interact with our marquee or as it's auto playing, we can actually see the different variables that are being set and make sure that it's actually progressing the way we've programmed it to.
