It's quite common to redirect a user visiting your webpage, more specifically when they perform an action, such as: clicking a button. When the user completes the action and you want to redirect the user to somewhere else, you have two common choices:

window.location.href = '';

OR

window.location.replace('');

This is not something I use everyday. Seems more like a once a year thing. Last time I needed to extract query string variables, I used the old school approach with a regular expression. Now that I need to do this again, I can use the new school approach: URLSearchParams.

The URLSearchParams (at the time of writing) is not yet standardized in the W3C; however, most modern browsers recognize it.

This morning I had to format a date using JavaScript as follows: yyyymmdd requiring both the month and day to include a leading zero when the month or day was less than 10. This solution using slice multiple times.

If you've used Knockout.js in your project, at some point or another you've probably encountered the following error "Uncaught ReferenceError: Unable to process binding". The most likely cause is a typo somewhere or forgetting to change the context. E.g. you are within a foreach binding and forget to use $parent.

I recently encountered this issue and could not find the typo anywhere. Like most developers in my situation I was getting really frustrated, banging my head against the world looking for answers.

Unfortunately, there is no easy answer to this bug; however, I can suggest an excellent technique that will hopefully help point you in the right direction.

Here is a complete example that creates a table and displays a list of books within the table. There is an unfortunate typo within one of the td data bindings.

I recently had the opportunity to begin exploring and toying around with Windows Phone 8 development.

Why you ask?  Why not really, but mostly because I was giving a free phone and it’s an untapped market when it comes to apps.  At this stage it’s not over diluted like the Android and iPhone stores are.  That and of course there is an option to create apps using HTML, Javascript, and CSS – technologies I’ve used and mastered for years!

I actually submitted my first app last weekend – and sadly – it got rejected :(  I was given two reasons; firstly I did set a default application icon, whoops my bad.  Secondly, I didn’t properly handle the back button since there are “multiple pages” in my application.

It took me several hours to finally found the answer so I thought I would share it.  Please note, this feels like a bit of a hack, but I wasn’t able to get the “suggested” solutions working…
