What are gotchas? They’re itty-bitty details that will bite you because you didn’t say the secret word or rub your belly 3 times while pressing the Enter key. Gotcha!
Internet Explorer
- You can’t have a popup window with a space in the name.
- When making an HTA, don’t open links inside the HTA. You can’t use
javascript:void(0)links, as it tries to open it as a new page and you get pleasant security warnings. Use “#” (which, unfortunately, can cause you to jump around the screen. Then use #top…)
Firefox
- There’s a focus bug in input areas. Workaround: Need an autocomplete flag
Programming
- Always, always rebuild clean. Check this first – you could be using old files, be in the wrong directory, or in the wrong terminal window.
Shell Scripting
- Beware newlines: Ran a commmand like this ver = “svn info | grep “Revision” | gawk …” to parse some input. Unfortunately, did not “chomp” off the newline at the end. The newline went into other commands, caused problems, and was hard to see.
Javascript
object[name] != object['name']. Beware a string in variable name and the string “name”. Confusing? Yes. Maybe there’s something to hungarian notation after all (no, no, just kidding!)CSS:
font-size: 10pxbecomes variableobject.style.fontSizein javascript. CSS proprties without dashes are the same (i.e., height).onpaste/oninputdetects paste events inside an input area from the mouse (onkeypresswon’t work).
Apache
- Need the qsa flag in order to pass the query string through for mod-rewrite rules (otherwise, you just get the page and not the query).
WordPress
- If your comments disappear suddenly, do a repair table with PhpMyAdmin (Operations > Repair Table)
