  • Force download through markup or JS

    - by mschoening
    Lets assume I have a file on a CDN (Cloud Files from Rackspace) and a static html page with a link to that file. Is there any way I can force download this file (to prevent it from opening in the browser -- for mp3s for example)? We could make our server read the file and set the corresponding header to: header("Content-Type: application/force-download") but we have about 5 million downloads per month so we would rather let the CDN take care of that. Any ideas?

  • Understanding NoSQL Data Modeling - blog application

    - by Rushabh RajeshKumar Padalia
    I am creating an blogging application in Node.js + MongoDB Database. I have used relational Database like MySQL before but this is my first experience with NoSQL database. So I would like to conform my MongoDB data models before I move further. I have decided my blogDB to have 3 collections post_collection - stores information about that article comment_collection - store information about comments on articles user_info_collection - contains user inforamtion PostDB { _"id" : ObjectID(...), "author": "author_name", "Date": new Date(....), "tag" : ["politics" , "war"], "post_title": "My first Article", "post_content": "Big big article" "likes": 23 "access": "public" } CommentDB { "_id" : Objectid(...), "POST": "My First Article", "comment_by": "User_name", "comment": "MY comments" } UserInfoDB { "_id": ObjectID(...), "user": "User_name", "password": "My_password" } I would appreciate your comments.

In IE nothing happens. I check in firebug lite and it is in HTML section, inside BODY tag but i see nothing. Whats wrong?

  • Javascript object encapsulation that tracks changes

    - by Raynos
    Is it possible to create an object container where changes can be tracked Said object is a complex nested object of data. (compliant with JSON). The wrapper allows you to get the object, and save changes, without specifically stating what the changes are Does there exist a design pattern for this kind of encapsulation Deep cloning is not an option since I'm trying to write a wrapper like this to avoid doing just that. The solution of serialization should only be considered if there are no other solutions. An example of use would be var foo = state.get(); // change state state.update(); // or state.save(); client.tell(state.recentChange()); A jsfiddle snippet might help : http://jsfiddle.net/Raynos/kzKEp/ It seems like implementing an internal hash to keep track of changes is the best option. [Edit] To clarify this is actaully done on node.js on the server. The only thing that changes is that the solution can be specific to the V8 implementation.

  • Toastr.js notifications as modal notfication

    - by Maxsteel
    I know it's not what toastr (or toast notifs in general) are meant to be used for, but I want to use them as a modal notification. My idea is following. On toast show: toastr.options.onShown = function() { //Create an overlay on the entire page} Overlay: #overlay { background-color: rgba(0, 0, 0, 0.8); z-index: 999; position: absolute; left: 0; top: 0; width: 100%; height: 100%; display: none; } And on toast close: toastr.options.onHidden = function() { //make overlay go away } Also, I'm setting timeout of toast to 0 so it won't disappear by itself. Question: I want the toast notification to stay atop the overlay and not behind it as overlay will cover everything. How can I do it?

I am using 1.0.2 Thank you!

  • Issue pushing object into an array JS

    - by Javacadabra
    I'm having an issue placing an object into my array in javascript. This is the code: $('.confirmBtn').click(function(){ //Get reference to the Value in the Text area var comment = $("#comments").val(); //Create Object var orderComment = { 'comment' : comment }; //Add Object to the Array productArray.push(orderComment); //update cookie $.cookie('order_cookie', JSON.stringify(productArray), { expires: 1, path: '/' }); }); However when I print the array this is the output: Array ( [0] => Array ( [stockCode] => CBL202659/A [quantity] => 8 ) [1] => Array ( [stockCode] => CBL201764 [quantity] => 6 ) [2] => TEST TEST ) I would like it to look like this: Array ( [0] => Array ( [stockCode] => CBL202659/A [quantity] => 8 ) [1] => Array ( [stockCode] => CBL201764 [quantity] => 6 ) [2] Array( [comment] => TEST TEST ) I added products to the array in a similar way and it worked fine: var productArray = []; // Will hold order Items $(".orderBtn").click(function(event){ //Check to ensure quantity > 0 if(quantity == 0){ console.log("Quantity must be greater than 0") }else{//It is so continue //Show the order Box $(".order-alert").show(); event.preventDefault(); //Get reference to the product clicked var stockCode = $(this).closest('li').find('.stock_code').html(); //Get reference to the quantity selected var quantity = $(this).closest('li').find('.order_amount').val(); //Order Item (contains stockCode and Quantity) - Can add whatever data I like here var orderItem = { 'stockCode' : stockCode, 'quantity' : quantity }; //Check if cookie exists if($.cookie('order_cookie') === undefined){ console.log("Creating new cookie"); //Add object to the Array productArray.push(orderItem);

  • Splitting Nucleotide Sequences in JS with Regexp

    - by TEmerson
    I'm trying to split up a nucleotide sequence into amino acid strings using a regular expression. I have to start a new string at each occurrence of the string "ATG", but I don't want to actually stop the first match at the "ATG". Valid input is any ordering of a string of As, Cs, Gs, and Ts. For example, given the input string: ATGAACATAGGACATGAGGAGTCA I should get two strings: ATGAACATAGGACATGAGGAGTCA (the whole thing) and ATGAGGAGTCA (the first match of "ATG" onward). A string that contains "ATG" n times should result in n results. I thought the expression /(?:[ACGT]*)(ATG)[ACGT]*/g would work, but it doesn't. If this can't be done with a regexp it's easy enough to just write out the code for, but I always prefer an elegant solution if one is available.

  • Get next key-value pair in an object

    - by captainclam
    So, given a key, I want to find the next property in an object. Then, I want to return the value of the NEXT property. I can not rely on the keys to be ordered or sequential (they're uuids). Please see below for trivial example of what I want: var db ={ a: 1, b: 2, c: 3 } var next = function(db, key) { // ??? } next(db, 'a'); // I want 2 next(db, 'b'); // I want 3 I also want a prev() function, but I'm sure it will be the same solution. This seems like such a trivial problem but I can't for the life of me figure out how to do it. Happy for the solution to use underscore.js or be written in coffeescript :)

  • require.js - How can I set a version on required modules as part of the URL?

    - by Ovesh
    I am using require.js to require JS modules in my application. I need a way to bust client cache on new JS modules, by way of a different requested URL. i.e., if the file hello/there.js has already been cached on the client, I can change the file name to force the browser to get the new file. In other words, for the module hello/there, I'd like require.js to request the url hello/there___v1234___.js (the file name can look different, it's just an example), according to a version string which is accessible on the client. What is the best way to achieve that?

  • I want to style within JS

    - by 422
    Issue I have is I can use tags, but I would like to style particular words. Adding a class doesnt work, is it because I am within script dom ? Example: var config = [ { "name" : "tour_1", "bgcolor" : "black", "color" : "white", "position" : "BR", "text" : "Customize your user profile, it's easy. This is your shop window on <strong>here</strong> and <strong>there</strong>", "time" : 4000 } Instead of strong, I would like to apply class, like <p class="orange"> But it wont have it, any suggestions... please

  • JS Split ( ) to check if substring exists in Array

    - by Javacadabra
    I have an array of products that are stored as Strings in this format productname:quantity. The issue I am running into is that if a user adds one product with a quantity of x it is inserted into the array as it should. However, if they then decide to add more of a particular product a new entry is made into the array instead of checking if the product already exists and adjusting the quantity to the new value. oldQty + newQty. For example this is my array: ["CBL202659/A:1","OUTER9:1","PALLET CARDS:1"] If I add another PALLET CARDS product it creates a new entry rather than updating the quantity of the existing item to 2. New array ["CBL202659/A:1","OUTER9:1","PALLET CARDS:1","PALLET CARDS:1"] I would like the array to end up like this: - updating the quantity ["CBL202659/A:1","OUTER9:1","PALLET CARDS:2"] Currently this is my code: I use the split() method to seperate the String where a colon occurs and store the product name and quantity in two seperate variables. $(".orderBtn").click(function(event){ //Show the order Box $(".order-alert").show(); event.preventDefault(); //Create the Array var productArray = []; //Get reference to the product clicked var stockCode = $(this).closest('li').find('.stock_code').html(); //Get reference to the quantity selected var quantity = $(this).closest('li').find('.order_amount').val(); var item = stockCode + ":" + quantity; var itemCheck = stockCode + ":"; if(quantity == 0){ console.log("Quantity must be greater than 0") }else{ //If no Cookie exists, create one and add the Array if ($.cookie('order_cookie') === undefined) { console.log("CREATE NEW COOKIE"); //Add items to Array productArray.push(item); //Add Array to Cookie $.cookie('order_cookie', JSON.stringify(productArray), { expires: 1, path: '/' }); //If the Cookie already exists do this } else { productArray = JSON.parse($.cookie('order_cookie'));//get ref to array if(productArray.indexOf(itemCheck)!= -1){//It exists so update qty console.log("EXISTS... updating item: " + itemCheck); //var index = productArray.indexOf(item); //var update = productArray[index].split(":"); //var name = update[0]; //var oldQty = update[1]; //console.log(name + ":" + oldQty); //productArray[index] = item; }else{//It does not exist, so add to array console.log("Does not exist... adding new item: " + item); //Append items onto the Array productArray.push(item); } //Update the Cookie $.cookie('order_cookie', JSON.stringify(productArray), { expires: 1, path: '/' }); console.log($.cookie('order_cookie')); } //Display the number of items in the Array in the Order Box $('#order_counter').html(productArray.length); } }); I suppose the real question I am asking here, is if it is possible to search the array for a subString - containing productname: ??

  • Hide / show content via CSS:hover (or JS if need be)

    - by Chris
    I have the following html: <li> <span class="one">Stuff here</span> <span class="two">More stuff</span> </li> .one { display: block; } .two { display: none; } What is the easiest method, preferably CSS only, to hide one and show two when the mouse rolls over the <li> container. If this cannot be done via CSS and only Javascript, I would prefer jQuery via something like live() as the content is updated live and do not wish to constantly rebind manually. EDIT: I forgot to mention that this has to work in IE6 :/
