  • jQuery UI Rang Slider show divs based on selected range

    - by andi_sf
    I have set up a range slider that should show/hide divs based on their range values - meaning if the range of the one specifies in the div falls into the selected range in the slider it should show - the others hide. Somehow it does not work correctly - if anybody could help that would be greatly appreciated. My code so far: $("#slider").slider({ range: true, min: 150, max: 280, step: 5, values: [150, 280], slide: function(event, ui) { $("#amount").val('Min. Value' + ui.values[0] + ' - Max. Value' + ui.values[1]); }, change: function(event, ui) { $('#col-2 div').each(function(){ var valueS = parseInt($(this).attr("class")); var valueX = parseInt($(this).attr("title")); if (valueS < ui.values[0] && valueX <= ui.values[1] || valueS ui.values[0] && valueX = ui.values[1] ) { $(this).stop().animate({opacity: 0.25}, 500) } else { $(this).stop().animate({opacity: 1.0}, 500) $("#amount").val('Min. Value' + ui.values[0] + ' - Max. Value' + ui.values[1]); } }); } }); $("#amount").val('Min. Value' + $("#slider").slider("values", 0) + ' - Max. Value' + $("#slider").slider("values", 1)); }); I have also posted a sample at: http://www.webdesigneroakland.com/slider/444range_slider.html

  • How to use VC++ intrinsic functions w/o run-time library

    - by Adrian McCarthy
    I'm involved in one of those challenges where you try to produce the smallest possible binary, so I'm building my program without the C or C++ run-time libraries (RTL). I don't link to the DLL version or the static version. I don't even #include the header files. I have this working fine. For some code constructs, the compiler generates calls to memset(). For example: struct MyStruct { int foo; int bar; }; MyStruct blah = {}; // calls memset() Since I don't include the RTL, this results in a missing symbol at link time. I've been getting around this by avoiding those constructs. For the given example, I'll explicitly initialize the struct. MyStruct blah; blah.foo = 0; blah.bar = 0; But memset() can be useful, so I tried adding my own implementation. It works fine in Debug builds, even for those places where the compiler generates an implicit call to memset(). But in Release builds, I get an error saying that I cannot define an intrinsic function. You see, in Release builds, intrinsic functions are enabled, and memset() is an intrinsic. I would love to use the intrinsic for memset() in my release builds, since it's probably inlined and smaller and faster than my implementation. But I seem to be a in catch-22. If I don't define memset(), the linker complains that it's undefined. If I do define it, the compiler complains that I cannot define an intrinsic function. I've tried adding #pragma intrinsic(memset) with and without declarations of memset, but no luck. Does anyone know the right combination of definition, declaration, #pragma, and compiler and linker flags to get an intrinsic function without pulling in RTL overhead?

  • How do I work with constructs in PHPUnit?

    - by Ben Dauphinee
    I am new into PHPUnit, and just digging through the manual. I cannot find a decent example of how to build a complete test from end to end though, and so, am left with questions. One of these is how can I prep my environment to properly test my code? I am trying to figure out how to properly pass various configuration values needed for both the test setup/teardown methods, and the configs for the class itself. // How can I set these variables on testing start? protected $_db = null; protected $_config = null; // So that this function runs properly? public function setUp(){ $this->_acl = new acl( $this->_db, // The database connection for the class passed // from whatever test construct $this->_config // Config values passed in from construct ); } // Can I just drop in a construct like this, and have it work properly? // And if so, how can I set the construct call properly? public function __construct( Zend_Db_Adapter_Abstract $db, $config = array(), $baselinedatabase = NULL, $databaseteardown = NULL ){ $this->_db = $db; $this->_config = $config; $this->_baselinedatabase = $baselinedatabase; $this->_databaseteardown = $databaseteardown; } // Or is the wrong idea to be pursuing?

  • jquery noob problem with variables (scope?)

    - by aharon
    I'm trying to retrieve data from a php file named return that just contains <?php echo 'here is a string'; ?> I'm doing this through an html file containing <!DOCTYPE html> <html> <head> <script src="http://code.jquery.com/jquery-latest.min.js"></script> <script> var x; $.get("return.php", function(data){ x = data; }) function showAlert() {alert(x);} $(document).ready(function(){ alert(x); }); </script> </head> <body> <input type = "button" value = "Click here" onClick="showAlert();"> </body> </html> When the button is clicked it retrieves and displays the code fine, but on the $(document).ready thing, it displays "undefined" instead of the data in return.php. Any solutions? Thanks.

  • Building a TriggerField with PopUp Window

    - by umit_alba
    Hi! I built a triggerField and when i press at it, i want to have a popup, that is appended to the button in the triggerfield(so when i click anywhere else it shall disappear and it shall pop out up to the button when i click at the button just like a datepicker-popup) I somehow managed to do something like that with an Ext.window but the offset and postion doesnt match. This all should be contained in a row editor. my Code: new Ext.grid.GridPanel({ store: Store, region:'center', height:150, //minWidth:700, autoScroll:true, listeners:{}, plugins:[new Ext.ux.grid.RowEditor()], tbar: [{ iconCls: 'icon-user-add', text: ' hinzufügen', handler: function(){ alert("abc"); } },{ ref: '../removeBtn', iconCls: 'icon-user-delete', text: 'löschen', disabled: true, handler: function(){ editor.stopEditing(); var s = grid.getSelectionModel().getSelections(); for(var i = 0, r; r = s[i]; i++){ store.remove(r); } } }], columns: [{ header: 'Monate', dataIndex: 'MONAT', width: 50, sortable: true, editor: new Ext.form.TriggerField({"id":"EditorMonate",items:[], "onTriggerClick":function(thiss){ if(!Ext.getCmp("autoWMonate")){ var monate=new Ext.Window({"x":Ext.getCmp("EditorMonate").x,closeAction:"hide",width:275,id:"autoWMonate",layout:"table",layoutConfig: {columns: 10}}); var text; for(var mon=1;mon<13;mon++){ text=mon; mon?mon:text="0"; if(mon<10) text="0"+mon; monate.items.add( new Ext.Button({cls:"x-btn",value:parseInt(text),selected:true,"text":text,id:text }}}));} } Ext.getCmp("autoWMonate").hidden?Ext.getCmp("autoWMonate").show():Ext.getCmp("autoWMonate").hide(); }}) } }] })

  • jquery clone only once

    - by tsiger
    I have a series of divs like this: <div id="available-posts"> <div class="post" id="unique_id"> <a href="#" class="addme">Add</a> Some text </div> <div class="post" id="unique_id"> <a href="#" class="addme">Add</a> Some text </div> </div> The unique_id is a different number for each of the divs. Now i have a new empty div like this <div class="related-posts"></div> And i clone items in there. The thing is that i want to check if an item is already cloned. If it is i want to stop it from being cloned again. This is how i clone items: // clone it $('.addme').live('click', function() { $(this).parents('div.thepost').clone().fadeIn('normal').appendTo('#related-posts').find('a.addme').html('Remove').removeClass('addme').addClass('removeme'); return false; }); // remove it $('.removeme').live('click', function() { $(this).parents('div.thepost').fadeOut('normal', function() {$(this).remove(); }); return false; }); In other words i want the cloned list to contain only unique items. Not for example 2 clones of the same post. *edit: i am using live coz the first list (available posts) is populated through an AJAX call.

  • Why is my PHP string being converted to 1?

    - by animuson
    Ok, so here's the quick rundown. I have a function to generate the page numbers. This: <?php die($ani->e->tmpl->pages("/archive", 1, 15, 1, true)); ?> will output Single Page like expected. But this: <?php $page_numbers = $ani->e->tmpl->pages("/archive", 1, 15, 1, true); ?> <?= $page_numbers ?> will output a simple 1 to the page. Why is it getting converted to a 1? I would expect it to store the 'Single Page' string to the page_numbers variable and then output it (like an echo) exactly the same. EDIT: Running a var_dump($page_numbers) returns int(1)... Here is the entire function in context: <?php // other functions... function show_list() { global $ani; $page_numbers = $ani->e->tmpl->pages("/archive", 1, 15, 1, true); ob_start(); ?> <!-- content:start --> <?php $archive_result = $ani->e->db->build(array("select" => "*", "from" => "animuson_archive", "orderby" => "0-time", "limit" => 15)); while ($archive = $ani->e->db->fetch($archive_result)) { ?> <h2><a href="/archive/article/<?= $archive['aid'] ?>/<?= $archive['title_nice'] ?>"><?= $archive['title'] ?></a></h2> <!-- breaker --> <?php } ?> <?= var_dump($page_numbers) ?> <!-- content:stop --> <?php $ani->e->tmpl->process("box", ob_get_clean()); } // other functions... ?>

  • Potential g++ template bug?

    - by Evan Teran
    I've encountered some code which I think should compile, but doesn't. So I'm hoping some of the local standards experts here at SO can help :-). I basically have some code which resembles this: #include <iostream> template <class T = int> class A { public: class U { }; public: U f() const { return U(); } }; // test either the work around or the code I want... #ifndef USE_FIX template <class T> bool operator==(const typename A<T>::U &x, int y) { return true; } #else typedef A<int> AI; bool operator==(const AI::U &x, int y) { return true; } #endif int main() { A<int> a; std::cout << (a.f() == 1) << std::endl; } So, to describe what is going on here. I have a class template (A) which has an internal class (U) and at least one member function which can return an instance of that internal class (f()). Then I am attempting to create an operator== function which compares this internal type to some other type (in this case an int, but it doesn't seem to matter). When USE_FIX is not defined I get the following error: test.cc: In function 'int main()': test.cc:27:25: error: no match for 'operator==' in 'a.A<T>::f [with T = int]() == 1' Which seems odd, because I am clearly (I think) defining a templated operator== which should cover this, in fact if I just do a little of the work for the compiler (enable USE_FIX), then I no longer get an error. Unfortunately, the "fix" doesn't work generically, only for a specific instantiation of the template. Is this supposed to work as I expected? Or is this simply not allowed? BTW: if it matters I am using gcc 4.5.2.

  • Version Control: multiple version hell, file synchronization

    - by SigTerm
    Hello. I would like to know how you normally deal with this situation: I have a set of utility functions. Say..5..10 files. And technically they are static library, cross-platform - SConscript/SConstruct plus Visual Studio project (not solution). Those utility functions are used in multiple small projects (15+, number increases over time). Each project has a copy of a few files or of an entire library, not a link into one central place. Sometimes project uses one file, two files, some use everything. Normally, utility functions are included as a copy of every file and SConscript/SConstruct or Visual Studio Project (depending on the situation). Each project has a separate git repository. Sometimes one project is derived from other, sometimes it isn't. You work on every one of them, in random order. There are no other people (to make things simpler) The problem arises when while working on one project you modify those utility function files. Because each project has a copy of file, this introduces new version, which leads to the mess when you try later (week later, for example) to guess which version has a most complete functionality (i.e. you added a function to a.cpp in one project, and added another function to a.cpp in another project, which created a version fork) How would you handle this situation to avoid "version hell"? One way I can think of is using symbolic links/hard links, but it isn't perfect - if you delete one central storage, it will all go to hell. And hard links won't work on dual-boot system (although symbolic links will). It looks like what I need is something like advanced git repository, where code for the project is stored in one local repository, but is synchronized with multiple external repositories. But I'm not sure how to do it or if it is possible to do this with git. So, what do you think?

  • How do I create efficient instance variable mutators in Matlab?

    - by Trent B
    Previously, I implemented mutators as follows, however it ran spectacularly slowly on a recursive OO algorithm I'm working on, and I suspected it may have been because I was duplicating objects on every function call... is this correct? %% Example Only obj2 = tripleAllPoints(obj1) obj.pts = obj.pts * 3; obj2 = obj1 end I then tried implementing mutators without using the output object... however, it appears that in MATLAB i can't do this - the changes won't "stick" because of a scope issue? %% Example Only tripleAllPoints(obj1) obj1.pts = obj1.pts * 3; end For application purposes, an extremely simplified version of my code (which uses OO and recursion) is below. classdef myslice properties pts % array of pts nROW % number of rows nDIM % number of dimensions subs % sub-slices end % end properties methods function calcSubs(obj) obj.subs = cell(1,obj.nROW); for i=1:obj.nROW obj.subs{i} = myslice; obj.subs{i}.pts = obj.pts(1:i,2:end); end end function vol = calcVol(obj) if obj.nROW == 1 obj.volume = prod(obj.pts); else obj.volume = 0; calcSubs(obj); for i=1:obj.nROW obj.volume = obj.volume + calcVol(obj.subs{i}); end end end end % end methods end % end classdef

  • backbone.js removing template from DOM upon success

    - by timpone
    I'm writing a simple message board app to learn backbone. It's going ok (a lot of the use of this isn't making sense) but am a little stuck in terms of how I would remove a form / html from the dom. I have included most of the code but you can see about 4 lines up from the bottom, the part that isn't working. How would I remove this from the DOM? thx in advance var MbForm=Backbone.View.extend({ events: { 'click button.add-new-post': 'savePost' }, el: $('#detail'), template:_.template($('#post-add-edit-tmpl').html()), render: function(){ var compiled_template = this.template(); this.$el.html(compiled_template); return this; }, savePost: function(e){ //var self=this; //console.log("I want you to say Hello!"); data={ header: $('#post_header').val(), detail: $('#post_detail').val(), forum_id: $('#forum_id').val(), post_id: $('#post_id').val(), parent_id: $('#parent_id').val() }; this.model.save(data, { success: function(){ alert('this saved'); //$(this.el).html('this is what i want'); this.$el.remove();// <- this is the part that isn't working /* none of these worked - error Uncaught TypeError: Cannot call method 'unbind' of undefined this.$el.unbind(); this.$el.empty(); this.el.unbind(); this.el.empty(); */ //this.unbind(); //self.append('this is appended'); } });

  • Checking for valid email addresses

    - by Roland
    I'm running a website with more than 60 000 registered users. Every week notifications are send to these users via email, now I've noticed some of the mail addresses do not exists anymore eg. the domain address is valid but the email name en asdas@ is not valid anymore since person does not work at a company anymore etc. Now I'm looping through the database and doing some regular expression checks and checking if the MX records exist with the following two functions function verify_email($email){ if(!preg_match('/^[_A-z0-9-]+((\.|\+)[_A-z0-9-]+)*@[A-z0-9-]+(\.[A-z0-9-]+)*(\.[A-z]{2,4})$/',$email)){ return false; } else { return true; } } // Our function to verify the MX records function verify_email_dns($email){ list($name, $domain) = split('@',$email); if(!checkdnsrr($domain,'MX')){ return false; } else { return true; } } If the email address is in an invalid format or the domain does not exists I delete the users account. Are there any methods I could use to check if the email address still exists or not if the domain name is valid and the email address is in the correct format? For example [email protected] does not exist anymore but test.com is a valid domain name.

  • Javascript check of a form, not waiting for ajax response

    - by Y.G.J
    this is a part of the check in my form function check(theform) { var re = /^\w[0-9A-Za-z]{5,19}$/; if (!re.test(theform.username.value)) { alert("not valid username"); theform.username.focus(); return false; } $.ajax({ type: "POST", url: "username.asp", data: "username="+theform.username.value, success: function(msg){ username = msg; if (!username) { alert("username already in use"); return false; } } }); var re = /^\w[0-9A-Za-z]{5,19}$/; if (!re.test(theform.password.value)) { alert("not valid password"); theform.password.focus(); return false; } } for some reason of sync... it check the username then duplicated username with the ajax and not waiting for respond and jump to the password check. i don't want to insert the rest of the code to isreadystate (or what ever it is) because i might move the username duplicate check to the end... and then the function will end before the ajax anyway what should i do?

  • Jquery and Ajax Post issue

    - by Jerry
    Hello guys I am trying to add a click event on the element that is return from the server via ajax. Apparently, I have to attached my js file inside my return response instead of my main script. Is this the best practice? Do I have to create the separated js file to add event on the return text?? Example: My Jquery - selectWeek.js $(document).ready(function(){ //handle ajax.. var url="sendSchedule.php"; $.post( url, {week:input}, function(responseText){ $("#ajax").html(responseText); }, "html" ); // click on #add button $("#add").click(function(){ //do something return false; }); }); My main page <script type="text/javascript" src="JS/selectWeek.js"></script> </HEAD> <BODY> //the code that trigger ajax is omitted <div id=ajax> //the response text will be inserted here </div> </BODY> </HTML> response from the server // display html (omit) // Do I have to attach the same js file to let #add listen the event? <script type="text/javascript" src="JS/selectWeek.js"></script> <form> <input type='button' id='add' value='add'/> </form> I am not sure if i make my question clear. I want to know if I need to add events on the return text. Do I have to add js file link on the return text or there is a way to do it on the main page. Thanks for any reply.

  • [Wordpress] How do you remove a Category-style (hierarchical) taxonomy metabox

    - by Manny Fleurmond
    I was wondering if someone can help me with this. I'm currently following Shibashake's tutorial about creating custom meta-boxes that include taxonomy selection here: http://shibashake.com/wordpress-theme/wordpress-custom-taxonomy-input-panels . They show how to remove the standard metabox Wordpress automatically creates for taxonomies using the remove_meta_box function. Only problem is that the function for some reason doesn't seem to work on taxonomies that work as categories ie ones where the hierarchical option is set to true. I know I have the function working because the ones set up as tags disappear easily enough. I can't if it just isn't possible or if there is something special I need to add in one of the parameters to make it work. Example: $args = array( 'hierarchical' => false, 'label' =>'People', 'query_var' => true, 'rewrite' => true ); register_taxonomy('people', 'post',$args); remove_meta_box('tagsdiv-people','post','side'); That works fine. If I set hierarchical to 'true, however, the meta box stays put. Can anyone shed some light?

    Hi all, I am building a simple facebook iframe application. I've decided since the code is separate from facebook none the less, I will also create a connect website as well. In my connect website I'm trying to figure out the following: I am using facebook's new api and I am calling the init function. I can't seem to figure out where I combine my cross-domain file.

  • URL shortening: using inode as short name?

    - by Licky Lindsay
    The site I am working on wants to generate its own shortened URLs rather than rely on a third party like tinyurl or bit.ly. Obviously I could keep a running count new URLs as they are added to the site and use that to generate the short URLs. But I am trying to avoid that if possible since it seems like a lot of work just to make this one thing work. As the things that need short URLs are all real physical files on the webserver my current solution is to use their inode numbers as those are already generated for me ready to use and guaranteed to be unique. function short_name($file) { $ino = @fileinode($file); $s = base_convert($ino, 10, 36); return $s; } This seems to work. Question is, what can I do to make the short URL even shorter? On the system where this is being used, the inodes for newly added files are in a range that makes the function above return a string 7 characters long. Can I safely throw away some (half?) of the bits of the inode? And if so, should it be the high bits or the low bits? I thought of using the crc32 of the filename, but that actually makes my short names longer than using the inode. Would something like this have any risk of collisions? I've been able to get down to single digits by picking the right value of "$referencefile". function short_name($file) { $ino = @fileinode($file); // arbitrarily selected pre-existing file, // as all newer files will have higher inodes $ino = $ino - @fileinode($referencefile); $s = base_convert($ino, 10, 36); return $s; }

  • Getting rid of nested using(...) statements

    - by Ghostrider
    Sometimes I need to use several disposable objects within a function. Most common case is having StreamReader and StreamWriter but sometimes it's even more than this. Nested using statements quickly add up and look ugly. To remedy this I've created a small class that collects IDisposable objects and disposes of them when it itself is disposed. public class MultiDispose : HashSet<IDisposable>, IDisposable { public MultiDispose(params IDisposable[] objectsToDispose) { foreach (IDisposable d in objectsToDispose) { this.Add(d); } } public T Add<T>(T obj) where T : IDisposable { base.Add(obj); return obj; } public void DisposeObject(IDisposable obj) { obj.Dispose(); base.Remove(obj); } #region IDisposable Members public void Dispose() { foreach (IDisposable d in this) { d.Dispose(); } } #endregion } So my code now looks like this: using (MultiDispose md = new MultiDispose()) { StreamReader rdr = md.Add(new StreamReader(args[0])); StreamWriter wrt = md.Add(new StreamWriter(args[1])); WhateverElseNeedsDisposing w = md.Add(new WhateverElseNeedsDisposing()); // code } Is there anything wrong with this approach that can cause problems down the road? I left the Remove function inherited from the HashSet on purpose so that the class would be more flexible. Surely misusing this function can lead to objects not being disposed of properly, but then there many other ways to shoot yourself in the foot without this class.

    I am trying to use Drew Dillard's awesome DD_belatedPNG fix + jQuery to achieve a run-of-the-mill image-swap on hover -- but with PNGs, and to work on IE6. Example: <a id="thelink" href="blah.html"><img src="f-u-ie6.png" /></a> Since DD's script sets the visibility of the original image to "hidden", you can't effectively hover over it. A lot of people, I have noticed, are thwarted by this limitation. Enough so that Drew mentioned he would try to get a work-around into the next version of his PNG fix. Well, in the meantime, I thought I could get around this by handling the hover event on the image's parent instead. So onmouseover, I would hide the VML object created by DD_belatedPNG while setting a background image on "thelink", and onmouseout, show the VML object again and set the background image to nothing. The following code was just to see if I could access the VML object, but it does not work on the VML. It hides all manner of other children, but not the VML. Any ideas? $(document).ready(function(){ $("thelink").hover(function() { $(this).children().attr({ style: "visibility:hidden" }); }, function() { $(this).children().attr({ style: "visibility:visible" }); }); }); Alternatively, can anyone suggest a great PNG image-swap method? I know that you can swap a background image of a link. But you still need to have something inside the A tag. That's not my case. Also, you could put a transparent GIF in the A tag and have the background image swapped to achieve the effect, but I really don't want to do that. Thanks for your insights!

  • Please help with passing multidimensional arrays

    - by nn
    Hi, I'm writing a simple test program to pass multidimensional arrays. I've been struggling to get the signature of the callee function. void p(int (*s)[100], int n) { ... } In the code I have: int s1[10][100], s2[10][1000]; p(s1, 100); This code appears to work, but it's not what I intended. I want to the function p to be oblivious whether the range of values is 100 or 1000, but it should know there are 10 pointers. I tried as a first attempt: void p(int (*s)[10], int n) // n = # elements in the range of the array and also: void p(int **s, int n) // n = # of elements in the range of the array But to no avail can I seem to get this correct. I don't want to hardcode the 100 or 1000, but instead pass it in, but there will always be 10 arrays. Obviously, I want to avoid having to declare the function: void p(int *s1, int *s2, int *s3, ..., int *s10, int n) FYI, I'm looking at the answers to a similar question but still confused.

  • Enum and Dictionary<Enum, Action>

    - by Selcuk
    I hope I can explain my problem in a way that it's clear for everyone. We need your suggestions on this. We have an Enum Type which has more than 15 constants defined. We receive a report from a web service and translate its one column into this Enum type. And based on what we receive from that web service, we run specific functions using Dictionary Why am I asking for ideas? Let's say 3 of these Enum contants meet specific functions in our Dictionary but the rest use the same function. So, is there a way to add them into our Dictionary in a better way rather than adding them one by one? I also want to keep this structure because when it's time, we might have specific functions in the future for the ones that I described as "the rest". To be more clear here's an example what we're trying to do: Enum: public enum Reason{ ReasonA, ReasonB, ReasonC, ReasonD, ReasonE, ReasonF, ReasonG, ReasonH, ReasonI, ReasonJ, ReasonK } Defining our Dictionary: public Dictionary<Reason, Action<CustomClassObj, string>> ReasonHandlers = new Dictionary<Reason, Action<CustomClassObj, string>>{ { Reason.ReasonA, HandleReasonA }, { Reason.ReasonB, HandleReasonB }, { Reason.ReasonC, HandleReasonC }, { Reason.ReasonD, HandleReasonGeneral }, { Reason.ReasonE, HandleReasonGeneral }, { Reason.ReasonF, HandleReasonGeneral }, { Reason.ReasonG, HandleReasonGeneral }, { Reason.ReasonH, HandleReasonGeneral }, { Reason.ReasonI, HandleReasonGeneral }, { Reason.ReasonJ, HandleReasonGeneral }, { Reason.ReasonK, HandleReasonGeneral } }; So basically what I'm asking is, is there a way to add Reason, Function pair more intelligently? Because as you can see after ReasonC, all other reasons use the same function. Thank you for your suggestions.
