I personally don't think it is better. I just think each one has its pros and cons. The clear fix technique frees one of having to write additional markup just for presentation, but I don't think...

Okay, so, now I see that somethings do now cause/throw exceptions. That is
clear. But then, I realized that I don't understand the difference (or advantage)
between simply using plain conditionals...

Can't I use try catch to prevent errors from breaking the applicaton?

Given this code?



$data = array('08/23'); // Note that there is no yyyy, only mm/dd.
list($dia, $mes, $ano) = explode('/', $data);


How can I use a try catch to avoid breaking my...

Note that I can indeed console.log(getId('form_list_users'));.



getId('form_list_users').reset(); // Stopped working.

What do you mean by "line feeds"? Do you mean the same as "new line" or "\n"?

Why even though there #text is 300 pixels wide, and #actions is 200 pixles wide, the #action div doesn't stay on the right top side of the header? It stays on the right, but #text doesn't let it sit...

It does. Thank you.

On a linux system, debian 6 to be more precise, php 5.3.3, what is the default email program that php uses to send emails with its mail() function?

Yeah, that is one thing that always work. I also found out that clearing the footer also works in this case. What I can't understand why appying the cf class to the footer doesn't work.

I cannot understad why this code doesn't prevent the footer from spanning up to the top with the clearfix hack. It does work with the overflow hidden technique, and also with the div with clear both....

It is from the book Pro Javascript Techniques, from John Resig. It is a function
that gets an attribute's value (or null) if two argumets are passed, and sets an
attribute's value if three...

Given this piece of code, I don't understand the part I commented:



function attr(elem, name, value) { // {{{

if (!name || name.constructor != String) return '';

This sounds like a course assignment.

What do you mean by "insert images" for instance. Does it mean, insert images on the page using javascript?

Of course. Since getText2(elem) uses 'elem' as argument, it is automatically a local variable. Thanks.

By the way, I remember when I was studying C, I also had a problem once, and it was the same...

I have a function to get text inside tags. One version works the other does not. The only difference is that in one I use 'elem' all the time, and in the other version I assign 'elem' to 'elems'....

This is my jQuery $.ajax code now, but I can't seem to get it to work.



jQuery(document).ready(function() {

I have this simple code. If the php function echoes the data, it works. If it just returns the data, I can't make jQuery .html() it into an element because "data" is always empty.

But my funcion only tries finding a sibling if the element the first child itself is different than nodeType 1:



e = e.firstChild;

function FCE(e) { // {{{
/* First Child Element - only tags, not text. */
e = e.firstChild;
do {
e = e.nextSibling;
} while (e && e.nodeType != 1);

I can't make jQuery add a class to the link (inside a list). I should click the link, load the page, and the link I have clicked should have a different color in order to show the user which page is...

9Now it half works, the blur event is not placing the original text back - not in IE.)
EDIT: It indeed works. I had forgotten to place the 'evt' argument in checkEmpty(evt). Sorry.

Also, where...

This is my code so far. It should handle all input text fields on a page. It works in opera, firefox, and chrome, all in their latest versions, except in IE6, which is the only IE version I have...

What if I just want to create an object, like:

How could I improve this code so that I didn't need to place all code inside initAll()?
