  • Configuring nginx to check for hard files in only a few directories,

    - by Evan Carroll
    For a node.js project I'm doing, I have a tree like this. +-- public ¦   +-- components ¦   +-- css ¦   +-- img +-- routes +-- views Essentially, I have the root to be set to public. I want all requests destined to /components/ /css/ /img/ To check to see if their appropriate destinations exist on disk. However, I don't want requests to other directories to even run an IO operation, /foo/asdf /bar /baz/index.html None of those should result in the disk being touched. I have a stansa that does the proxy to node.js, location @proxy { internal; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:3030; proxy_redirect off; } I just would like to know how to arrange this. My problem would be easily solved if try_files took a single argument, but it always wants a file first. location /components/ { try_files $uri, @proxy } location /css/ { try_files $uri, @proxy } location /img/ { try_files $uri, @proxy } However, there is nothing that I can find that will give me, location / { try_files @proxy } How do I get the effect I want?

  • MVC2 and jquery.validate.js

    - by Will I Am
    I am experiencing some confusion with jquery.validate.js First of all, what is MicrosoftMvcJqueryValidation.js. It is referenced in snippets on the web but appears to have dissapeared from the RTM MVC2 and is now in futures. Do I need it? The reason I'm asking is that I'm trying to use the validator with MVC and I can't get it to work. I defined my JS as: $(document).ready(function () { $("#myForm").validate({ rules: { f_fullname: { required: true }, f_email: { required: true, email: true }, f_email_c: { equalTo: "#f_email" }, f_password: { required: true, minlength: 6 }, f_password_c: { equalTo: "#f_password" } }, messages: { f_fullname: { required: "* required" }, f_email: { required: "* required", email: "* not a valid email address" }, f_email_c: { equalTo: "* does not match the other email" }, f_password: { required: "* required", minlength: "password must be at least 6 characters long" }, f_password_c: { equalTo: "* does not match the other email" } } }); }); and my form on the view: <% using (Html.BeginForm("CreateNew", "Account", FormMethod.Post, new { id = "myForm" })) { %> <fieldset> <label for="f_fullname">name:</label><input id="f_fullname"/> <label for="f_email"><input id="f_email"/> ...etc... <input type="submit" value="Create" id="f_submit"/> </fieldset> <% } %> and the validation method gets called on .ready() with no errors in firebug. however when I submit the form, nothing gets validated and the form gets submitted. If I create a submitHandler() it gets called, but the plugin doesn't detect any validation errors (.valid() == true) What am I missing?

  • Mimic.js handle fault response

    - by nikolas
    i use mimic.js regarding a project that i m developing.. the issue that i face, is if there is a fault response from the webservice, mimic, doesn't handle it, and the browser remains "awaiting" for a response, that has actually been back, but hasn't been handled by mimic.. to be more specific, one typical fault response is the following.. <?xml version="1.0" encoding="UTF-8"?> <methodResponse> <fault> <value> <struct> <member> <name>faultCode</name><value><int>104</int></value> </member> <member> <name>faultString</name><value><string>Invalid Input Parameters</string></value> </member> </struct></value></fault></methodResponse> and chrome console get me the error mimic.js:11 Uncaught TypeError: Cannot read property 'childNodes' of null any suggestions on how to handle "fault" responses? mimic.js hasn't been altered at all.. also tried to bypass the fact that mimic can't handle the fault, by trying to use the isFault flag, in the if statement, with no success either.. isFault is supposed to get a boolean value, i guess true/false?

  • Submit form with JS

    - by Thomas
    Im working with a shopping cart plugin and that uses a basic form on the product page to submit values like price, product name, etc.. The problem is that the plugin uses a standard submit button to send the values and I would like to replace said button with a prettier custom jquery rollover. In order to make this happen I used some JS and tossed a link around my custom submit button: <a href="#" onclick="document.forms[0].submit()" value="Add to Cart" onsubmit="return ReadForm(this, true);"> <img class="fade" src="style/img/add_btn.jpg" style="background: url(style/img/add_ro.png);" alt=""/> </a> The form submits and the user is redirected to the homepage but the data in the form doesn't seem to get submitted and the product never gets added to the 'cart' page. I suspect that the form is getting submitted but I am failing to fire some additional JS function that submits the data. The plugin adds some JS to the top of the page: <!-- // function ReadForm (obj1, tst) { // Read the user form var i,j,pos; val_total="";val_combo=""; for (i=0; i<obj1.length; i++) { // run entire form obj = obj1.elements[i]; // a form element if (obj.type == "select-one") { // just selects if (obj.name == "quantity" || obj.name == "amount") continue; pos = obj.selectedIndex; // which option selected val = obj.options[pos].value; // selected value val_combo = val_combo + "(" + val + ")"; } } // Now summarize everything we have processed above val_total = obj1.product_tmp.value + val_combo; obj1.product.value = val_total; } //--> If you want to check out the the site in question, take a look here and click 'add to cart button': http://hardtopdepot.com/?p=34 You can see the cart at the top: http://hardtopdepot.com/?page_id=50 Any help would be super appreciated- thanks!

  • Word-wrap grid cells in Ext JS

    - by richardtallent
    (This is not a question per se, I'm documenting a solution I found using Ext JS 3.1.0. But, feel free to answer if you know of a better solution!) The Column config for an Ext JS Grid object does not have a native way to allow word-wrapped text, but there is a css property to override the inline CSS of the TD elements created by the grid. Unfortunately, the TD elements contain a DIV element wrapping the content, and that DIV is set to white-space:nowrap by Ext JS's stylesheet, so overriding the TD CSS does no good. I added the following to my main CSS file, a simple fix that appears to not break any grid functionality, but allows any white-space setting I apply to the TD to pass through to the DIV. .x-grid3-cell { /* TD is defaulted to word-wrap. Turn it off so it can be turned on for specific columns. */ white-space:nowrap; } .x-grid3-cell-inner { /* Inherit DIV's white-space from TD parent, since DIV's inline style is not accessible in the column definition. */ white-space:inherit; } YMMV, but it works for me, wanted to get it out there as a solution since I couldn't find a working solution by searching the Interwebs.

  • Rails3 renders a js.erb template with a text/html content-type instead of text/javascript

    - by Yannis
    Hi, I'm building a new app with 3.0.0.beta3. I simply try to render a js.erb template to an Ajax request for the following action (in publications_controller.rb): def get_pubmed_data entry = Bio::PubMed.query(params[:pmid])# searches PubMed and get entry @publication = Bio::MEDLINE.new(entry) # creates Bio::MEDLINE object from entry text flash[:warning] = "No publication found."if @publication.title.blank? and @publication.authors.blank? and @publication.journal.blank? respond_to do |format| format.js end end Currently, my get_pubmed_data.js.erb template is simply alert('<%= @publication.title %>') The server is responding with the following alert('Evidence for a herpes simplex virus-specific factor controlling the transcription of deoxypyrimidine kinase.') which is perfectly fine except that nothing happen in the browser, probably because the content-type of the response is 'text/html' instead of 'text/javascript' as shown by the response header partially reproduced here: Status 200 Keep-Alive timeout=5, max=100 Connection Keep-Alive Transfer-Encoding chunked Content-Type text/html; charset=utf-8 Is this a bug or am I missing something? Thanks for your help!

  • asp.net mvc stand alone ascx control how do i link (css and js) most efficiently

    - by Julian
    Hi, I need some advice. I have developed some asp.net mvc web pages. Each page has a master and some ascx controls (between 2 - 6) embedded into it a js and css file. Up to now every thing was fine. In order to improve modularity, flexibility and testability the ascx's are now expected to be able to work as stand alone controls. (Each ascx has also got its own css and js files in some cases it has another control inside it) In order to meet this requirement we call the controller with the relevant parameters and it returns the ascx (partial) directly to the browser without all of the other parts of the original page . In order to get it to display correctly (css) and act correctly (js/jquery) all of the relevant files need to be added (as links or scripts eg. href="<%= ResolveUrl(styleSheet)%>") to the user control. This is "contradicting" the concept of positioning the files at the most logical place (could be the master page for example). How can I overcome this problem? Keep in mind that this is relevant for each "control" ascx file. Any thoughts will be appreciated.

  • JS/CSS include section replacement, Debug vs Release

    - by Bayard Randel
    I'd be interested to hear how people handle conditional markup, specifically in their masterpages between release and debug builds. The particular scenario this is applicable to is handling concatenated js and css files. I'm currently using the .Net port of YUI compress to produce a single site.css and site.js from a large collection of separate files. One thought that occurred to me was to place the js and css include section in a user control or collection of panels and conditionally display the <link> and <script> markup based on the Debug or Release state of the assembly. Something along the lines of: #if DEBUG pnlDebugIncludes.visible = true #else pnlReleaseIncludes.visible = true #endif The panel is really not very nice semantically - wrapping <script> tags in a <div> is a bit gross; there must be a better approach. I would also think that a block level element like a <div> within <head> would be invalid html. Another idea was this could possibly be handled using web.config section replacements, but I'm not sure how I would go about doing that.

  • Ext JS 4.2.1 loading controller - best practice

    - by Hown_
    I am currently developing a Ext JS application with many views/controlers/... I am wondering myself what the best practice is for loading the JS controllers/views/and so on... currently i have my application defined like this: // enable javascript cache for debugging, otherwise Chrome breakpoints are lost Ext.Loader.setConfig({ disableCaching: false }); Ext.require('Ext.util.History'); Ext.require('app.Sitemap'); Ext.require('app.Error'); Ext.define('app.Application', { name: 'app', extend: 'Ext.app.Application', views: [ // TODO: add views here 'app.view.Viewport', 'app.view.BaseMain', 'app.view.Main', 'app.view.ApplicationHeader', //administration 'app.view.administration.User' ... ], controllers: [ 'app.controller.Viewport', 'app.controller.Main', 'app.controller.ApplicationHeader', //administration 'app.controller.administration.User', ... ], stores: [ // stores in there.. ] }); somehow this forces the client to load all my views and controllers at startup and is calling all init methods of all controllers of course.. i need to load data everytime i chnage my view.. and now i cant load it in my controllers init function. I would have to do something like this i assume: init: function () { this.control({ '#administration_User': { afterrender: this.onAfterRender } }); }, Is there a better way to do this? Or just an other event? Though the main thing i am questioning myself is if it is the best practice to load all the javascript at startup. Wouldnt it be better to only load the controllers/views/... which the client does need right now? Or should i load all the JS at startup? If i do want to load the controllers dynamicly how could i do this? I assume a would have to remove them from my application arrays (views, controllers, stores) and create an instance if i do need it and mby set the view in the controllers init?! What's best practice??

  • Masonry js won't bunch images vertically

    - by user1449737
    The images are being aligned horizontally correctly but they are all spaced out vertically.. Take a look here http://brstudios.co.uk/testing to see what I mean properly.. My mark up is as followed (simplified): <html> <head> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript" src="http://masonry.desandro.com/jquery.masonry.min.js"></script> <script type="text/javascript" src="https://raw.github.com/desandro/imagesloaded/master/jquery.imagesloaded.min.js"></script> <script type="text/javascript"> var $container = $('.portfolio-container'); $container.imagesLoaded(function(){ $container.masonry({ itemSelector : '.break', columnWidth : 429 }); }); </script> <style type="text/css"> .break { float: left; width: 429px; margin: 10px 20px; } </style> </head> <body> <div class="portfolio-container"> <?php do { ?> <div class="break"> // Contents taken from MySQL // </div> <?php } while ($row_displayPosts = mysql_fetch_assoc($displayPosts)); ?> </div> </body> </html> I think part of it is working but as you can see by the link provided it isn't moving the elements together vertically. Does anyone have any pointers?

  • Isotope.js help: Changing item image after sorting

    - by user3643081
    This is a general question on how to go about building a project I have in mind, and the best way to set off on the right foot. I am fairly new to JS, please be gentle. I want to use isotope.js (or a similar script) to display a page with multiple items (about 30 different plants found in a garden) and the ability to sort them by seasons of the year + "what is most beautiful now" + and "view all" (a total of 6 categories) . On load, or when sorted by either "what is beautiful now" or "view all", I need each item to reflect the image of the current season we are in. When sorted by season, I need those "current" images to switch over to a designated seasonal image of that plant. Therefore, each sortable item will ultimately have 4 different versions with 4 different images in the background ready to surface when plants are sorted. (perhaps 5 if it makes more sense to have a "current" version besides the 4 seasonal versions.) My question: what approach can I take to achieve this effect in a manageable way? Can isotope apply a class to items sorted? Assuming it can: Should each item have 4 inline images, each with a css class, that I then control by using display:inline; and display:none; properties from my stylesheets? (I worry that this approach would significantly increase load times) Would it make more sense to create a blank dummy div who's background I control similarly to the example above -relying mostly on CSS. Or is there some other way involving JS I am overlooking? Any help would be appreciated. Examples of what you suggest would be immensely helpful.

  • JS: Storing dynamic variables across pages?

    - by user2467599
    I've been looking into local storage options and plugins like Persist.js, sessvars.js, and even sisyphus.js - but I am unsure if any are the best fit (though I'm fairly certain I need to use one). Page one is a form with input fields for data like names, phones, and email. I have a button that replicates a wrapper div (and it's inputs) as long as more inputs are needed. When the form is filled the user hits submit which takes them to a 'confirmation' type php page. I need to the give the user an 'edit' button on page 2 that takes them back to page 1 and leaves all the info alone. For the most part everything returns fine, but if the user had hit the 'replicate' button before submission, and then hits edit afterwards, all the inputs that were dynamically generated return empty and the div no longer exists. Someone suggested that my variables are not persistent (when the replicate button is hit, input with an id="name1" becomes "name2" and so on) so that's when I found out about the plugins mentioned before. Is there a way that I can implement one of those plugins (or any other method) so that when the user returns to page one the div and it's input values remain unchanged? And if I'm on the right track are there any examples?

  • how to use q.js promises to work with multiple asynchronous operations

    - by kimsia
    Note: This question is also cross-posted in Q.js mailing list over here. i had a situation with multiple asynchronous operations and the answer I accepted pointed out that using Promises using a library such as q.js would be more beneficial. I am convinced to refactor my code to use Promises but because the code is pretty long, i have trimmed the irrelevant portions and exported the crucial parts into a separate repo. The repo is here and the most important file is this. The requirement is that I want pageSizes to be non-empty after traversing all the dragged'n dropped files. The problem is that the FileAPI operations inside getSizeSettingsFromPage function causes getSizeSettingsFromPage to be async. So I cannot place checkWhenReady(); like this. function traverseFiles() { for (var i=0, l=pages.length; i<l; i++) { getSizeSettingsFromPage(pages[i], calculateRatio); } checkWhenReady(); // this always returns 0. } This works, but it is not ideal. I prefer to call checkWhenReady just ONCE after all the pages have undergone this function calculateRatio successfully. function calculateRatio(width, height, filename) { // .... code pageSizes.add(filename, object); checkWhenReady(); // this works but it is not ideal. I prefer to call this method AFTER all the `pages` have undergone calculateRatio // ..... more code... } How do I refactor the code to make use of Promises in Q.js?

  • convert ArrayList.toString() back to ArrayList in one call

    I have a toString() representation of an ArrayList. Copying the toString() value to clipboard, I want to copy it back into my IDE editor, and create the ArrayList instance in one line. In fact, what I'm really doing is this: my ArrayList.toString() has data I need to setup a unit test. I want to copy this ArrayList.toString() into my editor to build a test against this edge case I don't want to parse anything by hand My input looks like this: [15.82, 15.870000000000001, 15.92, 16.32, 16.32, 16.32, 16.32, 17.05, 17.05, 17.05, 17.05, 18.29, 18.29, 19.16] The following do not work: Arrays.asList() google collections Lists.newArrayList() Suggestions?

  • 'Set = new HashSet' or 'HashSet = new Hashset'?

    - by Pureferret
    I'm intialising a HashSet like so in my program: Set<String> namesFilter = new HashSet<String>(); Is this functionally any different if I initilise like so? HashSet<String> namesFilter = new HashSet<String>(); I've read this about the collections interface, and I understand interfaces (well, except their use here). I've read this excerpt from Effective Java, and I've read this SO question, but I feel none the wiser. Is there a best practice in Java, and if so, why? My intuition is that it makes casting to a different type of Set easier in my first example. But then again, you'd only be casting to something that was a collection, and you could convert it by re-constructing it.

  • .net dictionary and lookup add / update

  • Iterables.find and Iterators.find - instead of throwing exception, get null

    I'm using google-collections and trying to find the first element that satisfies Predicate if not, return me 'null'. Unfortunately, Iterables.find and Iterators.find throws NoSuchElementException when no element is found. Now, I am forced to do Object found = null; if ( Iterators.any( newIterator(...) , my_predicate ) { found = Iterators.find( newIterator(...), my_predicate ) } I can surround by 'try/catch' and do the same thing but for my use-cases, I am going to encounter many cases where no-element is found. Is there a simpler way of doing this?

  • Shortcut for adding to List in a HashMap

    - by Damo
    I often have a need to take a list of objects and group them into a Map based on a value contained in the object. Eg. take a list of Users and group by Country. My code for this usually looks like: Map<String, List<User>> usersByCountry = new HashMap<String, List<User>>(); for(User user : listOfUsers) { if(usersByCountry.containsKey(user.getCountry())) { //Add to existing list usersByCountry.get(user.getCountry()).add(user); } else { //Create new list List<User> users = new ArrayList<User>(1); users.add(user); usersByCountry.put(user.getCountry(), users); } } However I can't help thinking that this is awkward and some guru has a better approach. The closest I can see so far is the MultiMap from Google Collections. Are there any standard approaches? Thanks!

  • How can I create a collection of references in C#

    - by Jonathan Kaufman
    Ok I am having a cross language hiccup. In C# with it's great collections like List and I have: a Map class with properties of: List<byte[]> Images; List<Tile> Tiles; a Tile Class of: byte[] ImageData; int X; int Y; Now I want to add an image to the Map class and have the ImageData property of the Tile Classes to "reference" it. I have discovered I can't just assign it Images[0]. You can't have a reference to an object of a List. My fix was to create a Dictionary. Is this the best way or can I somehow have a "pointer" to a collection of objects?

  • C# - implementing GetEnumerator() for a collection inherited from List<string>

    Hi, I am trying to implement FilePathCollection. Its items would be simple file names (without a path - such as "image.jpg"). Once the collection is used via foreach cycle, it should return the full path created by concatenating with "baseDirectory". How can I do that? public class FilePathCollection : List<string> { string baseDirectory; public FileCollection(string baseDirectory) { this.baseDirectory = baseDirectory; } new public System.Collections.IEnumerator GetEnumerator() { foreach (string value in this._list) //this does not work because _list is private yield return baseDirectory + value; } } Thanks in advance! :-)

  • Subtracting two lists in Python

    - by wich
    In Python, How can one subtract two non-unique, unordered lists? Say we have a = [0,1,2,1,0] and b = [0, 1, 1] I'd like to do something like c = a - b and have c be [2, 0] or [0, 2] order doesn't matter to me. This should throw an exception if a does not contain all elements in b. Note this is different from sets! I'm not interested in finding the difference of the sets of elements in a and b, I'm interested in the difference between the actual collections of elements in a and b. I can probably work this out with a for loop, looking up the first element of b in a and then removing the element from b and from a, etc. But this doesn't appeal to me, I'd like to do this with list comprehension in a nice and easy way. Is this possible?

  • Is there a good collection library for C-language?

    - by matti
    We have to maintain and even develop C-code of our legacy system. Is there good collection library that would support Java/C# (new versions) style collections. Hashtable, HashSet, etc. Of course without objects, but with structs. The HashTable key limitations to "strings" and ints is not a problem. It wouldn't be bad if it's free even for commercial use. I'm back to C from C# and I must say i'm depressed using our own libraries and the language in general. We're using VS2005 and MS C-compiler if that has nothing to do with anything. Thanks & BR -Matti
