• Javascript regex: remove space(s) if not surrounded by a letter

  - by user326433

  I'm trying to clean some html text with javascript, there are white spaces included before and after some words (text is poorly formatted). Currently I have this regex: $("#" + target + " *").replaceText(/([\S][\u05B0-\u05C4]*)/gi, '<span class="marked">$1<\/span>'); This will capture all the non white-space characters and wrap them in a span element, but will not capture spaces between words (I need the span). How would you solve this?

• Test if links are external with jQuery / javascript?

  - by Matrym

  How do I test to see if links are external or internal? Please note: I cannot hard code the local domain. I cannot test for "http". I could just as easily be linking to my own site with an http absolute link. I want to use jQuery / javascript, not css. I suspect the answer lies somewhere in location.href, but the solution evades me. Thanks!

But, these rich server side libraries are not available within the browser, which causes a problem when trying to format data client side (AJAX style.) What javascript libraries and techniques are recommended for performing client side formatting and time-zone calculations? Also - beyond simple client side formatting, how can consistency be achieved when performing both server side and client side formatting?
