  • Getting the date object to work in IE6 (w/ YYYY-MM-DD param)?

    - by J. LaRosee
    I just got IE6 sprung on me for a project that is going out into the wild soon, which means it's time to go back and comb through all of the CSS and JS. I've gotten hung up on the date object, however: $.validator.addMethod("dateRange", function() { var today = new Date(); var event_date_raw = $('#event_date').val(); var event_date_parts = event_date_raw.split("-"); var event_date = new Date( event_date_parts[2]+","+event_date_parts[1]+","+event_date_parts[0] ); if( event_date.getTime() >= today.getTime() ) return true; return false; }, "Please specify a correct date:"); event_date.getTime() is returning "NaN" in IE6 so the validation fails. The event_raw_date is in the YYYY-MM-DD format, which date doesn't seem to mind in every other browser... Thoughts?

  • Parsing XML with jQuery

    - by Jamie
    I've used this: $(document).ready(function () { $.ajax({ type: "GET", url: "http://domain.com/languages.php", dataType: "xml", success: xmlParser }); }); function xmlParser(xml) { $('#load').fadeOut(); $(xml).find("result").each(function () { $(".main").append('' + $(this).find("language").text() + ''); $(".lang").fadeIn(1000); }); } I used a local XML file on my computer, it works fine, but when I change the URL to an website, it just keeps loading all the time... How do I get this to work?

  • JS Display Content based on Dropdown User input

    - by Thomas
    I am working on a search box that displays different options based on a users selection via dropdown box. Basically I need a really clean, light-weight method for switching out different divs without reloading the page. Im new to JS, but I know enough that there should be some really simple way of setting the display property using JS - Im just not totally sure how to go about it. Any help would be really appreciated, thanks.

  • Where do current (not HTML5) browsers stand on clipboard support for non-text data?

    - by John
    I don't really know where the line is between the browser itself and HTML/JS here. But let's say I want to write a web-app where I can copy a chunk of data from MSPaint (select, CTRL+c) and paste it into a web-page in some way... ultimately the point is the data goes to the server without me having to save it as a file first. Where are the problems here - browsers or client-side technologies? For instance if JS can't do it, could Flex/Silverlight? Advice on future technology welcome, but doesn't really answer the question - where are we right now with IE/FF/Chrome and JS/Flex/SL?

  • jQuery expanding menu

    - by Milen
    Hi everybody, i have this html code: <ul id="nav"> <li>Heading 1 <ul> <li>Sub page A</li> <li>Sub page B</li> <li>Sub page C</li> </ul> </li> <li>Heading 2 <ul> <li>Sub page D</li> <li>Sub page E</li> <li>Sub page F</li> </ul> </li> </ul> With this JS code: $(function(){ $('#nav>li>ul').hide(); $('#nav>li').mouseover(function(){ if ($('#nav ul:animated').size() == 0) { $heading = $(this); $expandedSiblings = $heading.siblings().find('ul:visible'); if ($expandedSiblings.size() > 0) { $expandedSiblings.slideUp(500, function(){ $heading.find('ul').slideDown(500); }); } else { $heading.find('ul').slideDown(1000); } } }); }) For now the code works this way: When click on Heading 1, menu is expanded. When click on Heading 2, heading2 submenu menu is expanded and heading 1 submenu is closed. I need to rework it to this: Submenus must be closed automatically on mouseout. Can somebody help me? Thanks in advance!

  • Openlayers and Bing Maps (POLYGONS)

    - by Jordan
    When trying to draw polygons onto a bing map, the initial marker is set differently on the map. How can I fix this? OpenLayers Bing Example <script src="OpenLayers.js"></script> <script> var map; function init(){ map = new OpenLayers.Map("map"); map.addControl(new OpenLayers.Control.LayerSwitcher()); var shaded = new OpenLayers.Layer.VirtualEarth("Shaded", { type: VEMapStyle.Shaded }); var hybrid = new OpenLayers.Layer.VirtualEarth("Hybrid", { type: VEMapStyle.Hybrid }); var aerial = new OpenLayers.Layer.VirtualEarth("Aerial", { type: VEMapStyle.Aerial }); var POLY_LAYER = new OpenLayers.Layer.Vector(); map.addLayers([shaded, hybrid, aerial, POLY_LAYER]); map.setCenter(new OpenLayers.LonLat(-110, 45), 3); var polygon = new OpenLayers.Control.DrawFeature(POLY_LAYER, OpenLayers.Handler.Polygon); map.addControl(polygon); polygon.activate(); } </script> Bing Example <div id="tags"> Bing, Microsoft, Virtual Earth </div> <p id="shortdesc"> Demonstrates the use of Bing layers. </p> <div id="map" class="smallmap"></div> <div id="docs">This example demonstrates the ability to create layers using tiles from Bing maps.</div> Of course the above is being initialized and page works. You can draw the polygon shapes. Notice if you zoom in or out one time, the markers are set at the correct coordinates. My app I was testing this on is really using the bing maps API keys and not VirtualEarth. But it's doing a similar thing. Is this an Openlayers bug? The below source came directly from the open layers example site, I just added and activated polygons to the map. Please let me know how I can fix this for using the Bing Map API.. I've been stuck on this for HOURS! :(

  • capturing click events on web-browser scrollbars

    - by The Code Pimp
    Hi, is it possible to capture a click event on a scrollbar? I have some code where i am observing the click and mousedown events on the document. However, it seems that when I click on the scrollbar, the event is not captured. This leads me to believe that the scrollbars aren't really part of the document. (Assumption :-)) Is this a correct assumption? What is the right way to do this so that the behaviour is consistent across all major browsers? sample code document.observe('click', function(evt){ //do something //blah blah blah }); Thanks

  • Array indexOf implementation for Internet Explorer

    - by Daemon
    There are plenty of solutions on how to get the indexOf implementation into the Array prototype so that it works under Internet Explorer, however I've stumbled upon an issue that doesn't seem to be addressed anywhere I've looked so far. Using the pretty well agreed upon implementation at MDC, I have the following code that's being problematic now: // indexOf support for IE (from MDC) if (!Array.prototype.indexOf) { Array.prototype.indexOf = function(elt /*, from*/) { var len = this.length >>> 0; var from = Number(arguments[1]) || 0; from = (from < 0) ? Math.ceil(from) : Math.floor(from); if (from < 0) from += len; for (; from < len; from++) { if (from in this && this[from] === elt) return from; } return -1; }; } var i = [1,2,3,4]; for (j in i) { alert(i[j]); } I am expecting to receive 4 alerts, each one containing one of the elements of the array. In Firefox and Chrome, that's exactly what I see, however in IE8 I get an additional alert containing the indexOf function code. What can be done to avoid this?

  • Proper Regex to find and replace escaped UTF-8 strings

    - by Piet Binnenbocht
    (edited) I am reading a JSON file that includes some UTF-8 characters that are encoded like this: "\uf36b". I am trying to write a RegExp to convert this to an HTML entity that looks like "&#x1F36B;". This displays the character correctly in my html page. I haven't been able to correctly display the character that should be associated with "\uf36b", especially when in a longer sentence that also includes other text. How can I write a regexp that replaces strings like "\uf4d6" and "\uf36b" but leaves other text alone? Example: var str = "I need \uf36b #chocolate"; This should be converted to: I need &#x1F36B; #chocolate;

  • jquery document.ready multiple declaration

    - by Hendry H.
    I realized that I can specify $(document).ready(function(){}); more than once. Suppose like this $(document).ready(function(){ var abc = "1122"; //do something.. }); $(document).ready(function(){ var abc = "def"; //do something.. }); Is this standard ? Those codes work on my FF (16.0.2). I just a little afraid that other browser may not. What actually happen ? How jQuery handle those code ? Thanks.

  • Empty "for" loop in Facebook ajax

    - by celticpride
    While surfing facebook and using the Firebug network debugger I noticed that facebook's AJAX responses all start with an empty for loop. Example: for(;;);{...} Does anyone know why this is done? I assume it's to prevent some sort of XSS attack but I don't totally understand. Thanks!

  • Removing DOM event handlers in long-running browser session

    - by Chris Beck
    I have a browser interface with a ul#contacts list on the left and div#contact property panel (email, phone) on the right. Click a contact in the list and my app makes an XHR request to get the contact property HTML fragment and update div#contact.innerHTML. Each contact fragment has an "Edit Contact" link. With JS, I progressively upgrade that link with an event listener that performs an XHR request to replace the static property panel with an in-place edit form. This can happen many times during a single browser session. How should I clean up my "Edit Contact" event listener? Do I need to remove it manually before the form overwrites the property panel? Or is the event listener cleaned up automatically when the contents of div#contact (and the node that I'm listening on) is overwritten? FWIW, I still consider IE6 to be part of my target market.

  • How do I handle the messages for a simple web-based live chat, on the server side?

    - by Carson Myers
    I'm building a simple live chat into a web application running on Django, but one thing I'm confused about is how I should store the messages between users. The chat will support multiple users, and a chat "session" is composed of users connected to one user that is the "host." The application is a sort of online document collaboration thing, so user X has a document, and users Y and Z would connect to user X to talk about the document, and that would be one chat session. If user Y disconnected for five minutes, and then signed back in and reconnected to user X, he should not get any of the messages shared between users X and Z while he was away. if users X, Y, and Z can have a chat session about user X's document, then users X and Y can connect to a simultaneous, but separate discussion about user Z's document. How should I handle this? Should I keep each message in the database? Each message would have an owner user and a target user (the host), and a separate table would be used to connect users with messages (which messages are visible to what users). Or should I store each session as an HTML file on the server, which messages get appended to? The problem is, I can't just send messages directly between clients. They have to be sent to the server in a POST request, and then each client has to periodically check for the messages in a GET request. Except I can't just have each message cleared after a client fetches it, because there could be multiple clients. How should I set this up? Any suggestions?
