HTML framesets

A FRAMESET takes the place of the BODY

javascript assignment to variables.

This example that shows how to force a page to be displayed inside a frame was confusing at first. The reason was that I didn't understand that.

var ar2;
var num = 2;
window["ar" + num] = "frame4.html";

is the same as

ar2 = = "frame4.html";

The definitive guide.

Just found out that JavaScript: The Definitive Guide, 4th Edition is available online! I'm not sure if this is complete or not but either way it will be useful.

javascript learning curve

I've been working my way through the javascript lessons in javascript mall. Things were pretty easy until lesson 10. Lesson 10 showed a script that makes a calendar. I entered this on my own and found out that the javascript interpreter is pretty silent about mistakes. I worked my way through putting a calendar together. My goal was to construct one that looked more or less like the one that they showed in the example but by writing the code on my own. I used their code only for occasional html reference.

The process went slowly. I wanted to not only get through the lesson but to develop techniques that would speed the development process. After a while I looked for tools online. The most helpful was firebug. I also tried jslint but I must not be using it right; I didn't get any useful information from it.

here's the finished product

After doing a windows update, I was getting an annoying error from some Nvidia rundll utility after every login. I tried using msconfig to fix this but it did not work. A little searching turned up autoruns which helped me take care of the problem.

javascript tutorial

Trying out:

javascript sandbox

Using as a test environment.
I need a testbed ; created but google said my javascript is unsafe and will be removed when viewing.

Also tried posting directly into this blog but that does not seem to work.


I'm going to spend some time learning javascript. While doing so I will record my javascript related experiences in this blog.
