  • jQuery: Replace strings with .each()

    - by Warrantica
    I want a function that replace each li with an image. This is my code: $(document).ready(function(){ var tmphref; var tmpname; var str = '<a href="' + tmphref + '"><img src="http://www.somesite.com/a/' + tmpname[1] + '/avatar-small.jpg /></a>'; $('#somediv li a').each(function(){ tmphref = $(this).attr("href"); tmpname = /http\:\/\/(\w+)\.somesite\.com\//.exec(tmphref); $(this).parent().replaceWith(str); }); }); The image is in this specific path: www.somesite.com/a/username/avatar-small.jpg The code above doesn't work. Any ideas? Thank you in advance.

  • PHP: Remove all fcn not acting as expected, Code Inside

    - by Josh K
    I made this simple function (remove all $elem from $array): function remall($array, $elem) { for($i=0; $i < count($array); $i++) if($array[$i] == $elem) unset($array[$i]); $newarray = array_values($array); return $newarray; } But it isn't working perfectly, here are some inputs and outputs $u = array(1, 7, 2, 7, 3, 7, 4, 7, 5, 7, 6, 7); $r = remall($u, 7); Output of $r: 12345767 $n = array(7, 7, 1, 7, 3, 4, 6, 7, 2, 3, 1, -3, 10, 11, 7, 7, 7, 2, 7); $r = remall($n, 7); Output of $r: 1346231-30117727 Notice how there are still 7s in my outputs. Also, My function will only be removing numbers from an array. Let me know if you spot something, thanks.

  • How can I have a Foo* iterator to a vector of Foo?

    - by mghie
    If I have a class that contains a std::list<Foo>, how can I implement iterators to a Foo* collection, preferably without using boost? I'd rather not maintain a parallel collection of pointers. For now I have std::list<Foo>, mostly so that removing or inserting an element does not invalidate all other iterators, but would it be possible to implement other iterators too, so that the collection type used in the implementation is opaque to the user of the class?

  • How is this regex wrong?

    - by Spot
    I have a regex which I'm using to match user functions inside an IDE (Sublime). This matches what I want (the function name itself), but it also matches the first parentheses. Therefore the match is like follows: this._myFunction('content'); Notice the opening paran. Here is my expression: (?:[^\._])?([\w-]+)(?:[\(]){1} How can I exclude the opening paran from getting matched? . As a bonus question: How can I successfully not match the string: function, because as you can expect function( matches (not fun in JS). Thank you to anyone who can assist.

  • javascript var declaration within loop

    - by Trouts
    hello, /*Test scope problem*/ for(var i=1; i<3; i++){ //declare variables var no = i; //verify no alert('setting '+no); //timeout to recheck setTimeout(function(){ alert('test '+no); }, 500); } it alerts "setting 1" and "setting 2" as expected, but after the timeout it outputs "test 2" twice - for some reason the variable "no" is not reset after the first loop... i've found only an "ugly" workaround... /*Test scope problem*/ var func=function(no){ //verify no alert('setting '+no); //timeout to recheck setTimeout(function(){ alert('test '+no); }, 500); } for(var i=1; i<3; i++){ func(i); } Any ideas on how to workaround this problem in a more direct way? or is this the only way?

  • How to $.extend 2 objects by adding numerical values together from keys with the same name?

    - by muudless
    I currently have 2 obj and using the jquery extend function, however it's overriding value from keys with the same name. How can I add the values together instead? obj1 = {"orange":2,"apple":1, "grape":1} obj2 = {"orange":5,"apple":1, "banana":1} mergedObj = $.extend({}, obj1, obj2); var printObj = typeof JSON != "undefined" ? JSON.stringify : function(obj) { var arr = []; $.each(obj, function(key, val) { var next = key + ": "; next += $.isPlainObject(val) ? printObj(val) : val; arr.push( next ); }); return "{ " + arr.join(", ") + " }"; }; console.log('all together: '+printObj(mergedObj) ); And I get obj1 = {"orange":5,"apple":1, "grape":1, "banana":1} What I need is obj1 = {"orange":7,"apple":2, "grape":1, "banana":1}

  • c# unicode string output

    - by Reg
    I have function to convert string to a Unicode string: private string UnicodeString(string text) { return Encoding.UTF8.GetString(Encoding.ASCII.GetBytes(text)); } But when I am calling this function the output result is wrong. It looks like my function is not working. Console.WriteLine(UnicodeString("????? ?????")) printing on console just questions like that: ????? ???? Is there any way to say to console to display it correct? UPDATE Looks like the problem not in Unicode, I think may be it is displaying question marks because i am not having correct locale in the system (Windows 7)? Is there any way to make it work without changing locale?

  • Does jquery require timestamp on GET Calls in IE7?

    - by Mithun P
    Please see the jQuery code below, it used to paginate some search results paginate: function() { $("#wishlistPage .results").html("<div id='snakeSpinner'><img src='"+BASE_URL+"images/snake.gif' title='Loading' alt='...'/></div>"); var url = BASE_URL+"wishlist/wishlist_paginated/"; $.ajax({ type: "GET", url: url, data: { sort_by:$('#componentSortOrder input:hidden').val(), offset:My.WishList.offset, per_page: 10, timestamp: new Date().getTime() }, success: function(transport){ $("#wishlistPage .results").html(transport); } }); }, My issue is not with the pagination, issue is when i need to call this same function when something happed to other part of the page which remove some search results, it brings the old results in IE7, other browsers works fine. So added the timestamp: new Date().getTime() part. That fixed the IE issue. I want o know why this happens in jQuery? Do I need to include a timestamp parameter to URL to avoid caching in all jQuery Ajax calls?

  • Dynamically choosing css property in animation

    - by paddywhack
    Hi, It seems a straightforward thing but I'm not having much success. I'm just implementing a simple animation moving a div left or up using animate() but I would like to be able to set the "top" and "left" css properties dynamically. I would like to use the same function rather than have to have two, one for "left" and one for "top". Here's some code which gives the idea. function test($element){ $element.click(function(){ var cssProperty; var direction = "left"; var moveTo = "100px"; if (direction === "top") { cssProperty = "top"; } else { cssProperty = "left"; } /*Using variable as CSS property - This doesn't work */ $(this).animate({ cssProperty: moveTo }, 1000); /*Using variable as the CSS Values - This does */ $(this).animate({ left: moveTo }, 1000); }); } Variables works on the css value side but not on the css selector side. Anyone have any suggestions? Thanks

  • Vew not updating after scope update

    - by bsparacino
    Here is a very simple example of what I am trying to do Athlete.save(athlete,function(result) { $scope.athlete = result.athlete; }); The issue is that the $scope.athlete variable does not update in my view. In order to get it to update I have to do this Athlete.save(athlete,function(result) { $scope.athlete.fname = result.athlete.fname; $scope.athlete.lname= result.athlete.lname; $scope.athlete.gender= result.athlete.gender; .... }); This gets annoying very quickly. With the first block of code it's as if angular does not know that my $scope.athlete variable has been updated. This function is triggered from an ng-click, not some jquery call, I am doing it the angular way as far as I know. here is a simpler case I made: http://plnkr.co/edit/lMCPbzqDOoa5K4GXGhCp

  • Is it possible to *optionally* override a theme in Drupal 6?

    - by David Semeria
    I want to override the theming of only one (custom) menu. I can do this with phptemplate_menu_tree() but - of course - it overrides the rendering of all menus. I've tried returning FALSE (an obvious technique IMO) if the menu is not the specific one I want to override - but this doesn't cause the overridden theme function to be called. My only alternative (when the menu is anything other than the specific one) is to call the overridden function from within phptemplate_menu_tree() - but this seems to defeat the whole point of the override system, since the default rendering function will be hard-coded therein. I hope the explanation is clear, and any help is greatly appreciated - tks.

Any ideas ?

  • jquery add remove objects

    - by Scarface
    Hey guys quick question, I have an add remove script that will add a unique element and should remove it on a click function but does not. I think it is because the added object is not in the DOM when page is loaded but I am not sure how to fix this. IF anyone has any advice I would greatly appreciate it. $(document).ready(function(){ if (action=='content-change'){ $('#droppable2-inner').empty().append('<div id="content-image"><img id="visual-background2" src=' + src + '></div><div id="drop-content" action="drop-image">x</div>'); } $("#drop-content").click(function() { $('#content-image').remove(); }); })

  • how to get the value of an php array in jQuery

    - by user1933824
    i have a PHP code that will obtain the total images of a certain website via CURL, and put it inside an PHP loop. $z=1; for ($i=0;$i<=sizeof($images_array);$i++) { ....<img src = "$images_array[$i]" id="$z"> .. $z++; } a user can then scan through the array with a prev/next button and the current image being shown will be displayed in my $('$current_image').val(1); $.post("curl_fetch.php?url="+ extracted_url, { }, function(response){ $('#loader').html($(response).fadeIn('slow')); $('#current_image').val(1); // insert loop value in .val() when i click a button, i want to get the value of the array, and not the loop value $(function() { $(document).on('click','.submit', function () { var img = $('#current_image').val(); //get the array value, not the loop value alert(img); });}); now, how do i properly get the array value in my $('#current_image').val(1); in Jquery.

  • Visual C++ CreateThread Parameter Problem

    - by Vanwaril
    I have a class that contains a function that calls create thread, and needs to pass itself (this) as a parameter: DWORD threadId; HANDLE h = CreateThread( NULL, 0, runThread, this, 0, &threadId); My runThread definition is as follows: DWORD WINAPI runThread(LPVOID args) { Obj *t = (Obj*)args; t->funct(); return 0; } Unfortunately, the object t that I get in runThread() gets garbage. My Obj class has a function pointer attribute. Could that be the problem? class Obj{ void(*funct)(); and in the constructor: Obj(void(*f)()) { funct = f; } where is my mistake? The function pointer, the createThread itself, or type-casting? I tried whatever I could think of.

  • How to efficiently render different things at different times in a game?

    - by Baqjohanson
    Sorry for the ambiguous title. What I am wondering is what is an efficient way to alternate rendering between lets say a main menu, options menu, and "in the game." The only two ways I've come up with so far are to have 1 render function, with code for each part (menu, ...) and a variable to control what gets drawn, or to have multiple render functions, and use a function pointer to point to the appropriate one, and then just call the function pointer. I always wonder how more professional games do it.

  • Play Framework Form "fold" method naming rationale

    - by oym
    Play Framework's (2.x) Form class has a method called fold who's usage is indicated as: anyForm.bindFromRequest().fold( f => redisplayForm(f), t => handleValidFormSubmission(t) ) Essentially, the first function parameter is what gets executed on binding failure, and the 2nd on binding success. To me it seems similar to the 'success' and 'error' callbacks of jquery's ajax function. My question is why did the Play developers call the method "fold"? As a disclaimer I am new to Scala, but I am failing to see the connection between this and the functional Scala fold operation. The only similarity is that it is a higher order function; but I don't see any combining that is taking place, nor does it delegate internally in its implementation to any of the Scala fold functions.
