Here’s your example in the “one” line.
this.$OuterDiv = $(‘
‘)
.hide()
.append($(‘
‘)
.attr({ cellSpacing : 0 })
.addClass(“text”)
)
;
Update: I thought I’d update this post since it still gets quite a bit of traffic. In the comments below there’s some discussion about $(“
“) vs $(document.createElement(‘div’)) as a way of creating new elements, and which is “best”.
I put together a small benchmark, and here are roughly the results of repeating the above options 100,000 times:
jQuery 1.4, 1.5, 1.6
Chrome 11 Firefox 4 IE9
420ms 650ms 480ms
createElement 100ms 180ms 300ms
jQuery 1.3
Chrome 11
3800ms
createElement 100ms
jQuery 1.2
Chrome 11
3500ms
createElement 100ms
I think it’s no big surprise, but document.createElement is the fastest method. Of course, before you go off and start refactoring your entire codebase, remember that the differences we’re talking about here (in all but the archaic versions of jQuery) equate to about an extra 3 milliseconds per thousand elements.
Update 2
Updated for jQuery 1.7.2 and put the benchmark on JSBen.ch which is probably a bit more scientific than my primitive benchmarks, plus it can be crowdsourced now!

Simply supplying the HTML of elements you want to add to a jQuery constructor $() will return a jQuery object from newly built HTML, suitable for being appended into the DOM using jQuery’s append() method.
For example:
var t = $(“
“);
$.append(t);
You could then populate this table programmatically, if you wished.
This gives you the ability to specify any arbitrary HTML you like, including class names or other attributes, which you might find more concise than using createElement and then setting attributes like cellSpacing and className via JS.
