javascript - jQuery Animate and Loops -


i made simple animation website jquery inside joomla!, seems fine have strange issue during loop. cells fixed dims. inside loop i. check here http://db.tt/uud00tkc issue happens firefox.

the js code is:

jquery(document).ready(function () { function loop() {     jquery("#txt1").animate({         backgroundcolor: "#0089bc"         }, 3000, function() {         loop();     });             jquery("#txt1").animate({         backgroundcolor: "#fff"         }, 3000);                 jquery("#txt2").animate({         backgroundcolor: "#0089bc"         }, 9000, function() {         loop();     });     jquery("#txt2").animate({         backgroundcolor: "#fff"         }, 9000);        jquery("#txt3").animate({         backgroundcolor: "#0089bc"         }, 6000, function() {         loop();     });             jquery("#txt3").animate({         backgroundcolor: "#fff"         }, 6000);                }     loop(); });  jquery(document).ready(function () {  jquery("#img1").hide().fadein(3000); setinterval(function () {             jquery("#img1").fadeout(3000).fadein(3000); }, 5000);      jquery("#img2").hide().fadein(9000); setinterval(function () {             jquery("#img2").fadeout(9000).fadein(9000); }, 5000);    jquery("#img3").hide().fadein(6000); setinterval(function () {             jquery("#img3").fadeout(6000).fadein(6000); }, 5000);        });

html code

<div id="home-mosaico"> <div class="row"> <span class="cell-img" id="img1"><img src="http://www.quatrotd.co.uk/images/home/substation-02.jpg" alt="substation" title="substation" /></span> <span class="cell" id="txt1">engineering<br />and construction</span> <span class="cell-img" id="img2"><img src="http://www.quatrotd.co.uk/images/home/substation-01.jpg" alt="substation" title="substation" /></span> </div> <div class="row"> <span class="cell" id="txt2">transmission lines</span> <span class="cell-img" id="img3"><img src="http://www.quatrotd.co.uk/images/home/transmision_lines-01.jpg" alt="transmision lines" title="transmision lines" /></span> <span class="cell" id="txt3">substations</span> </div> </div>

css code

/*** home mosaico ***/ #home-mosaico { display: table; width: 940px; height: 500px; } #home-mosaico .row { display: table-row; height: 250px;  } #home-mosaico .cell-img { display: table-cell; width: 313px; background-color: #0089bc; vertical-align:middle; text-align:center; font-size:20px; line-height: 24px; font-weight:normal; color:#ffffff; } #home-mosaico .cell { display: table-cell; width: 313px; background-color: #fff; vertical-align:middle; text-align:center; font-size:20px; line-height: 24px; font-weight:normal; color:#ffffff; }

your loop function looks run problems. loop function starts, keep recursively calling instantly putting large strain on browser there isn't seconds break between calls.

on top of that, of animations finished, additionally call loop function again compounding first issue. while animations may stack correctly (one after other on elements told animate), there huge amount of recursion occurring in loop function.

an alternative loop function still getting same effect (animation stacking) might like:

jquery(document).ready(function () {     var txt1animate = function()     {         jquery("#txt1").animate({             backgroundcolor: "#0089bc"             }, 3000, function(){             jquery(this).animate({                 backgroundcolor: "#fff"             }, 3000, txt1animate);         });     }     var txt2animate = function()     {         jquery("#txt2").animate({             backgroundcolor: "#0089bc"             }, 9000, function(){             jquery(this).animate({                 backgroundcolor: "#fff"             }, 9000, txt2animate);         });     }     var txt3animate = function()     {         jquery("#txt3").animate({             backgroundcolor: "#0089bc"             }, 6000, function(){             jquery(this).animate({                 backgroundcolor: "#fff"             }, 6000, txt3animate);         });     }      txt1animate();     txt2animate();     txt3animate(); });

this correctly wait first animation finish on element, second , once second complete start again. stops animation queue spiraling out of control 100s 1000s of animations being queued second.

addressing second part of question, calling fadeout , straight away calling fadein. while should queue animation, goes 12 seconds , have being called again looped setinterval. create issues in long term queue growing every 10 or seconds without chance of finishing.

jquery(document).ready(function () {      jquery("#img1").hide().fadein(3000);     var img1fade = function()     {         jquery("#img1").fadeout(3000).fadein(3000,function()         {             settimeout(img1fade,5000);         });     }      jquery("#img2").hide().fadein(9000);     var img2fade = function()     {         jquery("#img2").fadeout(9000).fadein(9000,function()         {             settimeout(img2fade,5000);         });     }      jquery("#img3").hide().fadein(6000);     var img3fade = function()     {         jquery("#img3").fadeout(6000).fadein(6000,function()         {             settimeout(img3fade,5000);         });     }      img1fade();     img2fade();     img3fade(); });

similar other code provided, loops on in way won't have huge queue of animations @ once. nicely waits fade in finish before running settimeout loop function again.

edit

picked 1 bug in code supplied originally, using $ jquery in code on site linked, required jquery instead.

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
