Video: Adding the jQuery document ready and mouse events

Now at this point we're ready to start writing some JavaScript. So let's open up the JavaScript file. From your text editor, go to File > Open. From the myTooltip folder, let's go into includes, and let's open up tooltip.js. So inside of here, we are going to write some jQuery to target that tooltip and then change the tooltip container content. So let's start by putting in jQuery's document ready, so that's $(), type in the word document inside of the parentheses, outside of the parentheses we are going to type .ready(); inside of the parentheses for ready, we are going to type function, another set of parentheses, beginning and ending bracket. Let's split the brackets open.

Adding the jQuery document ready and mouse events

Now at this point we're ready to start writing some JavaScript. So let's open up the JavaScript file. From your text editor, go to File > Open. From the myTooltip folder, let's go into includes, and let's open up tooltip.js. So inside of here, we are going to write some jQuery to target that tooltip and then change the tooltip container content. So let's start by putting in jQuery's document ready, so that's $(), type in the word document inside of the parentheses, outside of the parentheses we are going to type .ready(); inside of the parentheses for ready, we are going to type function, another set of parentheses, beginning and ending bracket. Let's split the brackets open.

So this is jQuery's document ready structure. So these instructions won't run until the HTML file has been loaded. So inside of the document ready, the first thing we want to do once the HTML has been loaded is target the tooltip and set the mouse events. So I am going to start with a $(), two tick marks inside for a string literal, we are going to search for .tooltip. This is going to target every HTML element in our page that has a tooltip, so we can have more than one on the page. Outside of the parentheses .mouseover, beginning and ending parentheses, outside of the parentheses we are going to type .mousemove, another set of parentheses, outside of those parentheses .mouseout, then a semicolon.

So we are attaching three properties onto the tooltip, mouseover, mousemove and mouseout. Inside of each one of these parentheses, we're going to actually target the mouse event itself. So inside of each one of these parentheses, we're going to put a custom function that targets the actual event. So we are going to type function(), inside of the parentheses, we are going to put letter e, outside of the parentheses, but still inside of the parentheses for mouseover, we are going to put beginning and ending bracket.

I am going to select this first one here, let's come over here and paste this inside of each of the parentheses for mousemove and mouseout. Once we have all of these in place, let's come over here and just split these open, split each one open on the brackets, just close up some negative space. So now we have an area to put instructions in for mouseover, for mousemove and mouseout, and we'll start that in the next movie.
