Sample text

Firebug highlights which element you are currently hovering over. It also highlights that element in the HTML tab. With the current element selected in the HTML tab, you can see the applied style information in the panel on the right (see Figure 1-5). You can even see when certain styles have been overwritten by other styles. So as you can see, the power of Firebug extends well beyond just JavaScript. Figure 1-5. Selected element in Firebug Instead of using alert statements or page logging, there are a number of hooks that Firebug adds that enable you to log information right into the Firebug console.

You can set up ranges such as {2,4}, which means that it must match a minimum of two characters in a row to a maximum of four characters in a row. You can leave out the second parameter to indicate that the match should start at a minimum number of characters and move up from there (example: {2,}). The + character matches the character one or more times. The * character matches the character zero or more times. In the following example, the first line makes sure that there’s at least one number in a numbers-only string; the second example could match against an empty string as well as a string that has one or more numbers in it: /^\d+$/ /^\d*$/ To remember matches, use round brackets ( ) to remember the match found.

Push(els[i]); return a; } This function takes two parameters: the node from which you want to search and the class name for which you want to search. It returns an array of elements with which you can iterate through. Taking a look at this function, first you create a regular expression object: var re = new RegExp('(^| )'+classname+'( |$)'); A regular expression is a syntax for doing string matching. It is very powerful, but also very confusing. I’ve hit my head against the wall many times trying to tame a regular expression.
