Yes, I can see how this works in the trivial case. How if I want to traverse a tree

Something like

var x={}
for (i=1;i<100;i++){
var g=g||x;
g[i]={};
g=&g[i]; // by reference to get...

Is there a way to do this php equivalent in javascript:

a=5;
b=&a;

b++;

alert(a) //6
alert(b) //6

I figured it out. You can't specify line height.

I made this:
input{
width: 450px;
line-height: 2.5em;
font-size: 2.0em;
padding: 10px;
margin: 10px;
}

which works fine for ff, but of course, chrome adds the padding outside of the...

To turn off the auto width features of tables in css and make a table stop overflowing out of its parent div, add the following to the table

Hi rpg

I read your question

The way rnd explained it to me, it's really clear in my head now. What better way to test it than to try to answer your question. The way I understand it, if...

I have no clue. And the thing is, you can try to test the code in a browser or two but because the browsers all react inconsistently, it's impossible to tell without someone with great experience in...

Your answer 3. was so unbelievable I had to do further research. I read your link and I read a lot more websites. If I interpret your answer correctly, this whole "this" thing is incredibly easy. ...

Sorry to exploit this situation, but no one has a really good page on "this" and you seem willing to slog with a rookie.

I read about the map function. It's like linear algebra, it transforms the...

This has been great!

I have one last question. When you used a Rectangle function on Square, you made

1. Rectangle.prototype.area.call(s)

but when you shared the prototypes with:...

Thanks for the thorough response. I looked up toSource(). If I only knew about it sooner. They really should have a little debug chapter that shows all the cool function that exists. I don't know...

I was reading the rhino book because I'm trying to understand scope. There was an example:

function Rectangle(w, h){
this.width = w;
this .height = h;
this.area=function(){ return...

I have to tell you that's amazing. I can understand php failing when you put in extraneous functions, but I guess I just thought Javascript would ignore unknown variables the way css would. I don't...

I'm trying to learn Javascript. Honestly, I don't know how you guys do it. Anyway, I wanted a little alert box to open when the url is loaded. So I tried a few permutations:
