Word Clock using jQuery

Sometime back in 2012 or 2013, I stumbled upon this site.  As you will see, it displays the current time but in a rather creative manner. Note that this “word clock” is built on Flash.

I thought it would be cool to create it in jQuery just as an exercise. So I started on it and it took just about under one hour to come up with a similar word clock built on jQuery. Here is the link for it. Go ahead and check the time.

When I created it, I wanted to make a blog post for explaining its code but was too lazy at that time. I still am. You can expect to see a blog post explaining it in detail this month this time though. Meanwhile, you can do the digging yourselves. It is just JavaScript after all. Just view source or use Chrome inspector or Firebug.

Quick Tip – TinyMCE : Use full url while inserting image

Problem:This is a common scenario. You are using tinyMCE in admin of a site to insert a link to image.  While displaying that image on frontend tinyMCE makes it relative path instead of absolute.
Solution:
When setting up tinyMCE set these 2 configuration options:

 

Both these options are true by default. As the name implies, “remove_script_host” removes the protocol and host part of URLs. “relative_urls” must be set to false is you want to set “remove_script_host” to false.

TinyMCE documentation for relative_urls and remove_script_host.

Hope it helps.

Javascript advice for beginners

As you know, Javascript can be thought of as an extension to HTML – this allows authors to incorporate some functionality into their website, from controlling webpage navigation to adding interactive content. Javascript is one of the best ways to jazz-up your webpage.

There are so many advantages of using  Javascript, so if you are right in the middle of setting up your very first website then you are sure to be interested in reading this blog post which will show you  some good Javascript books to get you started.

Javascript is used on almost all websites. Social networking sites like Facebook use it so we can post a status without leaving the page, while gaming sites like http://www.partycasino.com use it to make their content interactive, as well as animate their pages with pictures and videos. Javascript is also commonly used to record information about the user’s reading habits, like how long they stayed on a certain page and what they looked at. Let’s have a look at some handy Javascript books to get you started.

Code Snippet : javascript – Checking for blank spaces in sentence without regex

This is actually very interesting. I had a text field which expected a single word string and I had to check it on client side. Using jQuery and JavaScript’s split function we can easily check if an input string contains spaces or not.

split function accepts a delimiter as first parameter, a string as second paramter and splits the string into an array by that delimiter. Returns original string if delimiter is not found.

Here is the code I used :

 

jQueryUI Sortable-tr width reduces when used with table

I am working on a project where I need to make a list of items sortable. Naturally, I used jQueryUI’s sortable component. Now it works great for elements like ul, or ol or any other html structure.

In my case the items were in a table and I had to make the tr’s sortable. Implementing the sortable gave me the desired behavior. Here is the code I used:

But while dragging the rows, the width of cells inside currently dragged row was getting decreased, making the row appear far smaller than normal size and ugly. This is what I am talking about (note row #6):

I did a quick Google search and found the following solution which works well. You will have to use the “helper” option provided by jQuery UI api. Here is it how you use it:
