javascript - Swap an image without flicker while showing the new one immediately -


tl;dr: there way swap images reliably while showing whichever image being loaded @ time without causing page flicker?

i have 2 images , 2 buttons , when hover on 1 button shows 1 image. hovering on other button swaps second image. doing this:

$('#button1').mouseover(function() {     $('#image').attr('src', 'image1.png'); });  $('#button2').mouseover(function() {     $('#image').attr('src', 'image2.png'); });

this works fine when first image has loaded , second hasn't, doesn't show second image until has completed loading. try give user indication of when new image loading (which they're expecting appear immediately), forced add null image before these swaps, this:

$('#button1').mouseover(function() {     $('#image').attr('src', '#');     $('#image').attr('src', 'image1.png'); });  $('#button2').mouseover(function() {     $('#image').attr('src', '#');     $('#image').attr('src', 'image2.png'); });

this works great when 1 image loading showing image it's loading once both loaded, null image in between them causes flicker when switching images. thought fix turning null image off once both images loaded has turned out unreliable. both $('#image').prop('complete') , imagesloaded suggested in other locations on stackoverflow inconsistent @ noticing whether image has been loaded or not. detecting loaded images seems dead end.

i considered trying force images show , hide before , after created doesn't seem work @ though i'm not sure why. new 1 doesn't show while loading , i'm not sure if they're swapping properly:

$('#button1').mouseover(function() {     $('#image').hide();     $('#image').attr('src', 'image1.png');     $('#image').show(); });  $('#button2').mouseover(function() {     $('#image').hide();     $('#image').attr('src', 'image2.png');     $('#image').show(); });

is there way swap images reliably while showing whichever image being loaded @ time without causing page flicker haven't tried?

what you're wanting preload images cached in browser. there's no delay on mouse over. here's jquery plugin cache images , call them. 

$.fn.preload = function() {     this.each(function(){         $('<img/>')[0].src = this;     }); }  // usage:  $(['image1.png','image2.png']).preload();

this not code: credit james @ preloading images jquery

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...
