internet explorer - jQuery and JSON vs IE - SCRIPT5007: Unable to get value of the property -


i'm struggling script working. it's simple ajax call retrieve data php returns json code.

function refreshwindows(){ if(ajaxpull && ajaxpull.readystate != 4){     ajaxpull.abort(); } ajaxpull = $.ajax({     type: 'post',     url: $path,     data: {         ajax: true,         mode: 'update',         to: math.round(currentdate.gettime() / 1000),         from: math.round(previousdate.gettime() / 1000)     },     datatype: "json",     success: function (data) {         alert(data); //that's debug         $replies = data.updates;         $.each($replies ,function(group,value) {             if (value!=''){                 $("#group"+group+" .content").append(value);                 $("#group"+group+" .content").stop().animate({ scrolltop: $("#group"+group+" .content")[0].scrollheight }, 800);                 if (!$("#group"+group+" .window").is(':visible')) {                     $("#group"+group+" .bottombox").fadeto('fast', 0.5).fadeto('fast', 1.0);                 }             }         });         previousdate = currentdate;         currentdate = new date();         timecontroller.push( settimeout(function(){refreshchatwindows();}, 500) );     } });

}

the error in internet explorer is:

script5007: unable value of property 'updates': object null or undefined

everything works fine in firefox , google chrome.

initially code made using .get suggested switching .ajax - well, didn't help. tried using .done(function(data){ didn't work either. tried sending of data in url opposite data property, worked fine in ff, ie still popped same error. tried adding different headers php, example header('content-type: application/json'); didn't change anything. run out of ideas / possible solutions fine on stackoverflow, appreciated.

in ie went developer tools, network tab , tried see if works - yes, request being sent correctly data, , response receive correct json, in firefox:

{"updates":{"1":"","2":"","3":"","5":"","6":"","7":"","8":""},"time":{"from":"1367489761","to":"1367489761"}}

which gets me confused, cause i'd have thought undefined error might happen because not being sent in ie whatever reason, clearly: it's not case. json back. ie unknown reason still thinks data undefined.

ok, found solution finally. basically:

  • remove headers sent php script. especially: content-type headers. (luckily - seems sessions still can used)
  • use }).done(function ( data ) { instead of success: function (data) {

and that's all. started work. it's weird. seems shotgun tactic (randomly changing bits of code till works) valid way of solving problems. hehehe

Eclipse formatter for java ending braces -

i know if it's possible setup eclipse format braces using banner style. we're working code uses banner style formatting , keep consistent within team version control reasons. here's example of banner style formatting not familiar: public class foo { //------------------------ public static void main (string[] args) { boolean condition = true; try { if (condition) { system.out.println ("condition true"); } else system.out.println ("not condition"); } catch (exception ex) { // handle errors } } //------------------------ } update: name style ratliff. experiment java->code style->formatter preferences. "banner style" seems poor use of space given outline view , quick outline functionality.

ruby - Nesting modules inside of a Rails eninge gem -

what proper syntax nest child modules within parent module being isolate_namespace rails engine gem? # lib/myengine/engine.rb module myengine class engine < rails::engine isolate_namespace myengine # def ... end end for example. parent module myengine , child module blog. myengine share common domain, crud, taggable, searchable, etc, keep gem code dry , isolated main app (myapp), while inheriting isolated namespace , engine. are either of 2 approaches correct? refactor advice? # # lib/myengine/blog.rb module myengine module blog # def ... end end # b # lib/myengine/blog.rb module myengine class engine < rails::engine isolate_namespace myengine module blog # def ... end end end option a. correct, should lib/my_engine/blog.rb . can read more ruby & rails naming conventions here . further, if want put more modules or classes under blog namespace put them in folder lib/my_engine/blog , nest them under myengine::bl...

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...
