  • 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}

  • Some pro regular expressions help needed here

    - by Camran
    I need a special regular expression, have no experience in them whatsoever so I am turning to you guys on this one: I need to validate a classifieds title field so it doesn't have any special characters in it, almost. Only letters and numbers should be allowed, and also the swedish three letters å, ä, ö, and also not case sensitive. Besides the above, these should also be allowed: The "&" sign. Parenthesis sign "()" Mathematical signs "-", "+", "%", "/", "*" Dollar and Euro signs Accent sign or whatever it's called, for example in "coupé" the apostrophe above the "e". Double quote and singel quote signs. The comma "," and point "." signs Thanks

  • Preventing click event with jQuery drag and drop

    - by Sasha Yanovets
    I have an elements on page that are draggabe with jQuery. These elements have click event wich navigates to another page (ordinary links for example). What is the best way to prevent click from firing on dropping such element, while allowing clicking it in not drag and drop state? I have this problem with sortable elements, but think it is good to have solution for general drag and drop. I've solved the problem for myself. After that found that same solution exists for Scriptaculous, but maybe someone have a better way to achieve that.

  • Modifying html of dom element that was created after page loaded

    - by Ben321
    I have two separate AJAX calls. One that gets a list of items from a txt file and creates an HTML table out of them and one that talks to a database to find how much each item costs and then lists this in the corresponding table cell for each item (I know this may sound like a strange approach, but it's a good option in our case...). The issue is that the price is not getting written to the table since the table is created (or to be precise, the rows of the table are created) after the page loads. I'm not sure how to fix this. $(document).ready(function() { makeItemTable(); listPrices(); ... }); function makeItemTable() { $.ajax({ url: 'products.php', type: 'GET' }) .done(function(response) { $('.price-table > tbody').html(response); }) } function listPrices() { .ajax({ url: 'prices.php', type: 'GET' }) .done(function(response) { priceData = $.parseJSON(response); $('.price-table tr').each(function() { var item = $(this).find('td:nth-child(1)').text(); if (priceData[item]) { var price = priceData[item]; $(this).find('td:nth-child(2)').text(price); } }) }

  • HTML to automatically hide text depending on scrolled size (like in Gmail)?

    - by Stephen Cagle
    Look at your Gmail inbox. You have 3 main columns contains the Sender contains "THE_EMAIL_SUBJECT - THE_EMAIL_BODY" the date the email was sent on I note that when you resize the window, the Gmail web client automatically resizes the displayed text in the second column. It basically just truncates the text so that it always can display the sent on date to the right, and the sender to the left. It is a pretty neat effect, and I would like to have that effect for myself. Does anyone know how to do this in HTML/CSS/JS?

  • How to determine which element(s) are visible in an overflowed <div>

    - by jjross
    Basically, I'm trying to implement a system that behaves similar to the reading pane that's built into the Google Reader interface. If you haven't seen it, Google Reader presents each article in a separate box and as you scroll it highlights the current box (and marks the article as read). In addition to this, you can move forward or backward in the article list by clicking the previous and next buttons in the UI. I've basically figured out how to do most of the functionality. However, I'm not sure how I can determine which of my divs is currently visible in in the scrollable pane. I have a div that is set to overflow:auto. Inside of this div, there are other divs, each one containing a piece of content. I've used the following jquery plugin to make everything scroll based on a click of the "next" or "previous" button and it works like a charm: http://demos.flesler.com/jquery/serialScroll/ But I can't tell which div has "focus" in the scrollable pane. I'd like to be able to do this for two reasons. I'd like to highlight the item that the user is currently reading (similar to Google Reader). I need to do this regardless of whether or not they used the plugin to get there or used the browser's scroll bar. I need to be able to tell the plugin which item has focus so that my call to scroll to the "next" pane actually uses the currently viewed pane (and not just the previous pane that the plugin scrolled from). I've tried doing some searching but I can't seem to figure out a way to do this. I found lots of ways to scroll to a particular item, but I can't find a way to determine which element is visible in an overflowed div. If I can determine which items are visible, I can (probably) figure out the rest. I'm using jquery if that helps. Thanks!

  • Make div expand only horizontally when more floating divs are added to it

    - by Wesam
    I am trying to make a div that contains other floating divs to adjust its width such that adding more floating divs (dynamically using jQuery) will only expand the div in its width, not allowing the floating divs to create a new line. Therefore, I want to fix this issue such that each div with class grid-row only expands in width, and so I will be able to scroll using the overflow: scroll for the parent grid div. I have searched a lot for answers, and it seems that it is a famous issue. However, non of the answer solved my problem. I am currently doing this: <div id="grid_container"> <div id="grid"> <div class="grid_row"> <div class="module" id="experience"> Experience </div> <div class="header"> Google </div> <div class="header"> Microsoft </div> </div> <div class="grid_row"> </div> </div> </div> CSS: body { } #grid_container { margin: 50px auto; width: 500px; height: 500px; padding: 10px; border: black solid 1px; } #grid { overflow:scroll; height: 100%; } .grid_row { clear: both; height: 50px; } .module, .header{ padding: 10px; float: left; border: gray solid 1px; }

  • Change URL of a saved HTML file

    - by Paul Camilleri
    I am new to HTML so this question might sound a bit lame. Anyways I have a saved webpage on my desktop that when i open it in google chrome i want it to show a specific URL instead of its current location. Any ideas how i might get this to work? I tried using the history.pushState but i have no idea why it is not working. I created a simple page for now to test it: <html> <head> <script> function setURL() { history.pushState("Test","page2", "www.test.com"); } </script> </head> <body> <button type="button" onclick="setURL()">Set Url</button> </body> </html> Any help would be greatly appreciated. Thank you

  • SO style alert header

    - by Zachary
    I apologize if this question is vague, but I want to build a drop down header, very similar to the one on StackOverflow that alerts you whenever you have earned a new badge, or on Twitter whenever a new tweet comes in. I've been looking around on the internet for a tutorial, but I'm having trouble googling exactly what I'm looking for. I assume there is a way to do this in jQuery, or there may be a jQuery plugin for it, but I haven't had any luck finding one. The idea would probably be to make an AJAX request every so many seconds, and if a new alert-worthy item is found, display it for the user. If someone could point me to a resource to learn how to build one, and/or an existing plugin, that would be great.

  • Check for changes with jquery and a database

    - by Steve
    I am doing a notification system. When a new post is published, users will be notified immediately by an small notification on the screen. I am currently using this: setInterval(function(){ checkForChanges(); }, 2*1000); function checkForChanges(){ $.post("http://"+ document.domain + "/posts/checkForChanges/", function(dat){ if(dat>0){ .... /*create notification*/ } }); } And i was wondering if this is the correct way to do it or not. Because, this is calling a PHP function every 2 seconds and making a query to the database. In case there are no new changes, it won't do anything... Thanks.
