Find empty DOM elements and remove them with Jquery/Javascript -


i have 3 columns, each of them containing div. these div's filled data happens, these div's empty , in case screw layout. want check if div's filled data (html) , if not, remove them. made if-statements i'm sure can done smoother.

here js code:

if ($.trim($(".fcol1").html()) =='') {    $(".fcol1").remove(); }  if($.trim($(".fcol2").html()) == '') {    $(".fcol2").remove(); }  if($.trim($(".fcol3").html()) == '') {    $(".fcol3").remove(); }

so, there way shorten code?

if they're truly empty, can do:

$(".fcol1:empty, .fcol2:empty, .fcol3:empty").remove();

...but if have blank text node in them, won't work. do:

$(".fcol1, .fcol2, .fcol3").filter(function() {     return !$.trim(this.innerhtml); }).remove();

note original code checks first element matching selector and, if 1 element empty, deletes all matching elements whether they're empty or not. e.g., if first .fcol1 empty, all .fcol1s deleted. (perhaps have 1 of each...)

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
