Convert XML tags and text to a String

Today I started testing a lot of my JavaScript / jQuery code from a website I am building for a customer. I got an error, at some point, saying:

SCRIPT5007: Unable to get property 'replace' of undefined or null reference

The error was in link with the 'replace' function being referenced on an innerHTML of an element. More specifically, one of those XML element (probably the top most one.)

The fact is that Internet Explorer does not support innerHTML in an XML document. Not to be too surprised about that, XML is not HTML so there is really no reason why innerHTML should be ...

My JavaScript code does not get the correct widget size, why?

As I am developing a set of pages for a customer, I ran in an intersting problem: my JavaScript function could not properly define the sizes of a box.

That box is heavily tweaked with the CSS assigned to it, as well as all of its neighbors. So I thought that may have something to do with it.

What I hadn't realized so far is that the ready() function of jQuery() is called once the script that includes it is ready (as in loaded) and not once the document as a whole is ready (done loading, i.e. onload event.)

With that knowledge it was easy to understand that I was actually finding myself ...

HTML background that fits the screen

You can actually define an image or a background (with CSS) that fits the area in which is it shown.

For a simple image use a width of 100%, then the browser computes the height for you.

  <div class="header"><img src="images/background.png" width="100%"></div>

This code will make the image width match the width of the <div> tag. Assuming the <div> tag fits the screen width, it will show in the full width, stretching as required.

When trying to do that with a background image in CSS, you want to use the background-size parameter ...

Useful online network tools

I'm starting this page and hope to think about it again at a later time when I find additional tools... but as I have network problems I often need these types of services to make sure I can get the information I need.

Your Bookmarks are auto-backed up in SeaMonkey! (and maybe FireFox?)

I started the stock SeaMonkey browser by mistake as my Unity icons disappeared (i.e. seamonkey as is on my command line started /usr/bin/seamonkey which is not the correct version!) This had several bad side effects. For of all, it destroyed my bookmarks (argh!) and then it decided to install the 64bit Flash plugin. That did not work well since the version I like is a 32bit version.

Once I had the correct version started again, each time it was trying to open a Flash animation, it would be "stuck" for a few minutes, until I tried to open a page with a movie in a Flash shell. That ...

Drupal blocks all disappeared!

Today I had an interesting experience... all of a sudden, all the blocks of a given theme disappeared.

It has been working just fine for months, so I really wasn't sure what the heck it could be.

The fact was that the theme was called the same as the module (as I work for a given client, I tend to do that...)

At some point, I must have added a function with a specific name and that would influence the theme. The result being blocks going bye bye!

I checked and the block content is computed just fine, the problem is the theme('block', $block) call. Although the ...

get_defined_vars() PHP function

Once in a while, I need to get the complete list of all the variables available in a PHP piece of code.

This is done with the get_defined_vars() PHP function. It's very simple, it returns an array of name / value pairs. You can then print that value using print_r() or var_dump().

That's it!

cellpadding="..." and cellspacing="..." not working

Today I was trying to create a table in a post and just could not get the cell padding I wanted. Without the padding the data is all cramped together which did not look the way I wanted (see Alexis Wilke Accounts.)

I knew I had the following entry in my CSS but did not think it was stronger than the table cellpadding and cellspacing specifications because I thought it worked for me before!

* {
  margin: 0;
  padding: 0;
}

I was wrong, that definition applies to the td with a greater constrained. So I had to add another entry. I solved the problem using a td definition like this:


Restore Firefox warnings when viewing non-secure data on a secure page

One thing that I quickly do on my browsers is turn off warnings about non-secure data when browsing secure pages (with HTTPS .)

It's rarely a problem and with all those features you like to have (Facebook, Twitter, AddThis, ShareThis, Google Plus, and othe fun widgets...) it's hard to avoid. Actually, many times the problem lies in one of these scripts and thus you cannot just fix your website. Without that 3rd party script owner fixing their code, it just won't work at all.

Now, once in a while I work on a customer website and they really want to have a 100% clean slate. Thus,

.change() not working right in Internet Explorer

I had a problem with jQuery and was wondering what could be wrong. Looking around for a solution, it was clear that Internet Explorer is the problem. Not the other way around (As usual.) The thing is that the function works, just not in realtime.

So... I have a Terms and Conditions flag, when you click it, I want to enable the Submit button in the form (by default the button is disabled.)

So I have a function something like this:

var valid = function check_valid() {
  // compute valid
  var valid = ...;
  // assume valid === true if button should be enabled

    Inter-Network. The Internet was created at a University to attempt to connect computers between each others from "far away places" (i.e. two buildings in the same University). The main concept was to create a set of protocols to make the systems work. Namely, the SMTP, FTP and TELNET. Now we have many others such as the well known HTTP, which is based on the TELNET concept.
