Yes it does!

 

Cheers HartleySan, I don't use the scripts for the book, I write the html out myself to practise. It didn't occur to me to check the html, I guess that's why I have the "newbie" on my user

 

Thanks for the quick reply.

[Chapter 8 Page 293]

Hi all,

 

I have just completed chapter 8 of the book and came across something I don't quite understand. In chapter 8 page 293 we make a new function call setHandlers and have an array of events in string format named events. In step 6, the code loops through the array and calls the following code:

 

var checkbox = U.$(events);

 

If I'm not wrong the U.$ is a function in a global object that returns the element for the passed in Id (the code in my U.$ function after checking for type string is return document.getElementById(id)). Now later in step 7 the code checks if the checkbox is checked like so:

 

if (checkbox.checked) etc.

 

Now after reading some materials online, I still don't understand how it is we can get a reference to the checkbox by passing in the name of an event to the U.$ method. Everywhere where I have read, the method accepts only the name of an element, so how is it that when we pass in an event name say 'mouseover', that we get a reference to the checkbox, so we can check if it is checked etc.

 

I'm new to Javascript, so if I've made a mistake in the above explanation, I apologise.

 

Thank you all in advance.
