问题 I have a string formatted as either Today 3:28AM Yesterday 3:28AM 08/22/2011 3:28AM What I need to do is somehow extract into a variable the date portion of my string, ie.

问题 I'm trying to create a simple page that "corrects" YouTube's old embed code so that it works in PowerPoint 2010. If I hard code the embed code into a textarea on the page, it works fine, but if the user pastes the embed code into the text area, the javaScript doesn't seem to run.

问题 There are lots of search results on the web (and in SO) for something similar to what I need to do, but I haven't run into a solution yet for my particular situation. I have a comma-delimited file in which only columns that have commas within them have double quotes around them. Other fields that have no comma in them are simply separated by the comma. Take this example: 123,"box,toy",phone,"red,car,cat,dog","bike,pencil",man,africa,yellow,"jump,rope" The output for that line needs to be: 123
