This column is part of the DHTML Lab thread: Creating a Web Application |
It can be appreciated by users of any browser, any version. In-page examples will work only in Explorer 4+ and Navigator 4+. |
In our last column, Array Power, Part II, we continued prototyping Array object methods built-in to Netscape Navigator but missing from Internet Explorer.
Using the prototype property of the Array object, we created two new methods for Explorer, aligning it to the Navigator and ECMAScript standard:
push() and pop()
We also discussed the differences between the JavaScript 1.2 and JavaScript 1.3+ implementations of Array.push in Navigator, and forced JavaScript 1.2 interpretors to use JavaScript 1.3+ functionality.
In this column, the final one of three devoted to the topic, we'll look at the complex splice() method.
Once again, we'll prototype it for Explorer, and modify the built-in behavior assigned to it by JavaScript 1.2 in older versions of Navigator.
A reading of our previous columns: Array Power, Part I and Array Power, Part II.
An understanding of the functionality of the built-in (to both browsers) slice() method for the Array object. We will be using this method in our functions. See the documentation at Netscape or Microsoft.
Familiarity with the prototype property of JavaScript objects. See Doc Javascript's Inheritance through Prototypes
First, let's see what splice() does.
