Javascript works for a lot of things. It's easy to sneak into other things, so it is useful to have around. Here are a few tihngs that I've found to be helpful, maybe you can do something with them too.
Image not found
Code that loads another image when the one you want can’t be found. I will tell you, this one takes a little while to work because the browser really wants to load the right image so it takes a little while before it will quit.
Mobile Detection
Check to see if your site is on a mobile device. Sounds easy enough, right? Oh… I’m checking orientation too (landscape vs portrait)
Load Page into DIV
Sometimes, you just want to load things into a DIV tag, without all that hub-bub. Here is how I do it.
OK, so I do it with an array, but I love arrays, and tend to sneak them into everything. I can’t help it.
Count Down to New Page
This is a little bit of code that I used for a demo, where I would play a gif for a few seconds before loading a page. I wanted a count down timer so that people knew they weren’t stuck watching a GIF forever.
Re-formatting bad JSON
Google sent me some crap JSON like [{“cake:yummy,belt:tight,brown,leather,car:fast”}] it should look more like [{“cake”:”yummy”,”belt”:”tight,brown,leather”,”car”:”fast”}] even then, KnockOut.js wants it to look like: [{cake:”yummy”,belt:”tight,brown,leather”,car:”fast”}] …so this is how I fixed it.
