Shortcuts for query selections and getComputedStyle

Here are some shortcuts for query selector, query selector all as well as getComputedStyle. These are helpful when you don’t have tools such as jQuery. During my JavaScript development work at Tremor Video, I have instances where I need to manipulate the DOM really quickly and it is better to rely on vanilla JavaScript for these rather than to call a library for this.

The caveat is that query selector and query selector all is only supported by Internet Explorer 8 and above. For getComputedStyle, it is not available for IE8 unless you have a shim. I use the getComputedStyle in Aight to provide for IE8. Firefox and Chrome aren’t affected by these.

Have fun, hope it’s helpful to you as it is to me.
