  • Show / Hiding Divs

    - by Rob
    After cobbling together a few questions I've managed to get this far to showing / hiding divs: $(document).ready(function(){ $('.box').hide(); $('#categories').onMouseOver(function() { $('.box').hide(); $('#div' + $(this).val()).show(); }); }); HTML: <div id="categories"> <div id="btn-top20"><a href="">Top 20 Villas</a></div> <div id="btn-villaspec"><a href="">Villa Specials</a></div> <div id="btn-staffpicks"><a href="">Our Staff Picks</a></div> </div> <div id="category-content"> <div id="divarea1" class="box"> Content 1 </div> <div id="divarea2" class="box"> Content 2 </div> <div id="divarea3" class="box"> Content 3 </div> </div> What am I missing?

  • Flash doesn't connect to socket even though policy allows it

    - by Bart van Heukelom
    In my Flash app, I'm connecting to my server like this: Security.loadPolicyFile("xmlsocket://example.com:12860"); socket = new Socket("example.com", 12869); socket.writeByte(...); ... socket.flush(); At port 12860 I'm running a socket policy server, which (according to this document) correctly serves up my policy like this: 00000000 3c 70 6f 6c 69 63 79 2d 66 69 6c 65 2d 72 65 71 <policy- file-req 00000010 75 65 73 74 2f 3e 00 uest/>. 00000000 3c 63 72 6f 73 73 2d 64 6f 6d 61 69 6e 2d 70 6f <cross-d omain-po 00000010 6c 69 63 79 3e 3c 73 69 74 65 2d 63 6f 6e 74 72 licy><si te-contr 00000020 6f 6c 20 70 65 72 6d 69 74 74 65 64 2d 63 72 6f ol permi tted-cro 00000030 73 73 2d 64 6f 6d 61 69 6e 2d 70 6f 6c 69 63 69 ss-domai n-polici 00000040 65 73 3d 22 6d 61 73 74 65 72 2d 6f 6e 6c 79 22 es="mast er-only" 00000050 20 2f 3e 3c 61 6c 6c 6f 77 2d 61 63 63 65 73 73 /><allo w-access 00000060 2d 66 72 6f 6d 20 64 6f 6d 61 69 6e 3d 22 2a 22 -from do main="*" 00000070 20 74 6f 2d 70 6f 72 74 73 3d 22 31 32 38 36 39 to-port s="12869 00000080 22 20 2f 3e 3c 2f 63 72 6f 73 73 2d 64 6f 6d 61 " /></cr oss-doma 00000090 69 6e 2d 70 6f 6c 69 63 79 3e 00 in-polic y>.

It's made (I can see with Wireshark and on the server), but no data is sent by Flash. It might be worth knowing that the SWF itself is served from example.com as well.

  • Closing InfoWindow with Google Maps API V3

    - by Oscar Godson
    I've seen the other posts, but they dont have the markers being looped through dynamically like mine. How do I create an event that will close the infowindow when another marker is clicked on using the following code? $(function(){ var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 10, center: latlng, disableDefaultUI:false, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $.getJSON('api',function(json){ for (var property in json) { if (json.hasOwnProperty(property)) { var json_data = json[property]; var the_marker = new google.maps.Marker({ title:json_data.item.headline, map:map, clickable:true, position:new google.maps.LatLng( parseFloat(json_data.item.geoarray[0].latitude), parseFloat(json_data.item.geoarray[0].longitude) ) }); function buildHandler(map, marker, content) { return function() { var infowindow = new google.maps.InfoWindow({ content: '<div class="marker"><h1>'+content.headline+'</h1><p>'+content.full_content+'</p></div>' }); infowindow.open(map, marker); }; } new google.maps.event.addListener(the_marker, 'click',buildHandler(map, the_marker, {'headline':json_data.item.headline,'full_content':json_data.item.full_content})); } } }); });

  • How can I differentiate a manual scroll (via mousewheel/scrollbar) from a Javascript/jQuery scroll?

    - by David Murdoch
    UPDATE: Here is a jsbin example demonstrating the problem. Basically, I have the following javascript which scrolls the window to an anchor on the page: // get anchors with href's that start with "#" $("a[href^=#]").live("click", function(){ var target = $($(this).attr("href")); // if the target exists: scroll to it... if(target[0]){ // If the page isn't long enough to scroll to the target's position // we want to scroll as much as we can. This part prevents a sudden // stop when window.scrollTop reaches its maximum. var y = Math.min(target.offset().top, $(document).height() - $(window).height()); // also, don't try to scroll to a negative value... y=Math.max(y,0); // OK, you can scroll now... $("html,body").stop().animate({ "scrollTop": y }, 1000); } return false; }); It works perfectly......until I manually try to scroll the window. When the scrollbar or mousewheel is scrolled I need to stop the current scroll animation...but I'm not sure how to do this. This is probably my starting point... $(window).scroll(e){ if(IsManuallyScrolled(e)){ $("html,body").stop(); } } ...but I'm not sure how to code the IsManuallyScrolled function. I've checked out e (the event object) in Google Chrome's console and AFAIK there is not way to differentiate between a manual scroll and jQuery's animate() scroll. How can I differentiate between a manual scroll and one called via jQuery's $.fn.animate function?

  • Lights off effect and jquery placement on wordpress

    - by Alexander Santiago
    I'm trying to implement a lights on/off on single posts of my wordpress theme. I know that I have to put this code on my css, which I did already: #the_lights{ background-color:#000; height:1px; width:1px; position:absolute; top:0; left:0; display:none; } #standout{ padding:5px; background-color:white; position:relative; z-index:1000; } Now this is the code that I'm having trouble with: function getHeight() { if ($.browser.msie) { var $temp = $("").css("position", "absolute") .css("left", "-10000px") .append($("body").html()); $("body").append($temp); var h = $temp.height(); $temp.remove(); return h; } return $("body").height(); } $(document).ready(function () { $("#the_lights").fadeTo(1, 0); $("#turnoff").click(function () { $("#the_lights").css("width", "100%"); $("#the_lights").css("height", getHeight() + "px"); $("#the_lights").css({‘display’: ‘block’ }); $("#the_lights").fadeTo("slow", 1); }); $("#soft").click(function () { $("#the_lights").css("width", "100%"); $("#the_lights").css("height", getHeight() + "px"); $("#the_lights").css("display", "block"); $("#the_lights").fadeTo("slow", 0.8); }); $("#turnon").click(function () { $("#the_lights").css("width", "1px"); $("#the_lights").css("height", "1px"); $("#the_lights").css("display", "block"); $("#the_lights").fadeTo("slow", 0); }); }); I think it's a jquery. Where do I place it and how do I call it's function? Been stuck on this thing for 6 hours now and any help would be greatly appreciated...

  • PHP: retrieve all declared namespaces of a DOMElement

    - by soulmerge
    I am using the DOM extension to parse an xml file containing xml namespaces. I would have that namespace declarations are treated just like any other attribute, but my tests seem to disagree. I have a document that starts like this: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns="http://purl.org/rss/1.0/" xmlns:taxo="http://purl.org/rss/1.0/modules/taxonomy/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:syn="http://purl.org/rss/1.0/modules/syndication/" xmlns:prism="http://purl.org/rss/1.0/modules/prism/" xmlns:admin="http://webns.net/mvcb/" > And a test code like this: $doc = new DOMDocument(); $doc->loadXml(file_get_contents('/home/soulmerge/tmp/rss1.0/recent.xml')); $root = $doc->documentElement; var_dump($root->tagName); # prints 'string(7) "rdf:RDF"' var_dump($root->attributes->item(0)); # prints 'NULL' var_dump($root->getAttributeNode('xmlns')); # prints 'object(DOMNameSpaceNode)#3 (0) {}' So the questions are: Does anyone know where could I find the documentation of DOMNameSpaceNode? A search on php.net does not yield any useful result. How do I extract all those namespace declarations from that DOMElement?

  • Adding jQuery event handler to expand div when a link is clicked

    - by hollyb
    I'm using a bit of jQuery to expand/hide some divs. I need to add an event handler so that when a link is clicked, it opens a corrisponding div. Each toggled div will have a unique class assigned to it. I am looking for some advice about how to build the event handler. The jQuery $(document).ready(function(){ $(".toggle_container:not(:first)").hide(); $(".toggle_container:first").show(); $("h6.trigger:first").addClass("active"); $("h6.trigger").click(function(){ $(this).toggleClass("active"); $(this).next(".toggle_container").slideToggle(300); }); The css: // uses a background image with an on (+) and off (-) state stacked on top of each other h6.trigger { background: url(buttonBG.gif) no-repeat;height: 46px;line-height: 46px;width: 300px;font-size: 2em;font-weight: normal;} h6.trigger a {color: #fff;text-decoration: none; display: block;} h6.active {background-position: left bottom;} .toggle_container { overflow: hidden; } .toggle_container .block {padding: 20px;} The html has a list of links, such as: <a href="#">One</a> <a href="#">Two</a> and the coorisponding divs to open: <h6 class="trigger">Container one</h6> <div class="toggle_container"> div one </div> <h6 class="trigger">Container two</h6> <div class="toggle_container Open"> div one </div> As I mentioned, I will be assigning a unique class to facilitate this. Any advice? Thanks! To clarify, i'm looking for some advice to build an event handler to toggle open a specific div when a link is clicked from a different part of the page, from a nav for instance.

  • How do I get Google Chrome's root bookmarks folder?

    - by Wayne
    Hi, I'm trying to write a better bookmark manager in chrome extensions. The problem is there are no simple examples (that I can find) about how to actually use the bookmarks api (available here: http://code.google.com/chrome/extensions/bookmarks.html ) I've looked at the example source (when I d/led and installed it on my computer it didn't do anything except provide a search box. Typing/typing and pressing return failed to do anything) and can't find anything useful. My ultimate goal is to make an extension that allows me to save pages to come and read later without having to go sign up for an account on some service somewhere. So I plan to create either one or two bookmark folders in the root folder/other bookmarks - at minimum an "unread pages" folder. In that folder I'll create the unread bookmarks. When the user marks the item as read, it will be removed from that folder. So that's what I'm trying to do... any help will be greatly appreciated, even if it's just pointing me to some good examples. UPDATE: ...<script> function display(tree){ document.getElementById("Output").innerHTML = tree; } function start(){ chrome.bookmarks.getTree(display); } </script> </head> <body> <h4 id="Output"></h4> <script> start(); </script> ... That displays [object Object], that suggests (at least to me with a limited JavaScript experience) that an object exists. But how to access the members of that object? changing tree to tree.id or any other of what look to be parameters displays "undefined".

  • How to define multiple elements in XML Schema with the same name and different attribute value allow

    - by David Skyba
    I would like to create XML Schema for this chunk of xml, I would like to restrict the values of "name" attribute, so that in output document on and only one instance of day is allowed for each week day: <a> <day name="monday" /> <day name="tuesday" /> <day name="wednesday" /> </a> I have tried to use this: <xs:complexType name="a"> <xs:sequence> <xs:element name="day" minOccurs="1" maxOccurs="1"> <xs:complexType> <xs:attribute name="name" use="required"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="monday" /> </xs:restriction> </xs:simpleType> </xs:attribute> </xs:complexType> </xs:element> <xs:element name="day" minOccurs="1" maxOccurs="1"> <xs:complexType> <xs:attribute name="name" use="required"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="tuesday" /> </xs:restriction> </xs:simpleType> </xs:attribute> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> but XML Schema validator in eclipse says error "Multiple elements with name 'day', with different types, appear in the model group.". Is there any other way?

  • How to clean completly select2 control?

    - by Candil
    I'm working with the awesome select2 control. I'm trying to clean and disable the select2 with the content too so I do this: $("#select2id").empty(); $("#select2id").select2("disable"); Ok, it works, but if i had a value selected all the items are removed, the control is disabled, but the selected value is still displayed. I want to clear all content so the placeholder would be showed. Here is a example I did where you can see the issue: http://jsfiddle.net/BSEXM/ HTML: <select id="sel" data-placeholder="This is my placeholder"> <option></option> <option value="a">hello</option> <option value="b">all</option> <option value="c">stack</option> <option value="c">overflow</option> </select> <br> <button id="pres">Disable and clear</button> <button id="ena">Enable</button> Code: $(document).ready(function () { $("#sel").select2(); $("#pres").click(function () { $("#sel").empty(); $("#sel").select2("disable"); }); $("#ena").click(function () { $("#sel").select2("enable"); }); }); CSS: #sel { margin: 20px; } Do you have any idea or advice to this?

  • Using a string inside the DocumentBuilder parse method (need it for parsing XML using XPath)

    - by dierre
    Hi guys! I'm trying to create a RESTful webservice using a Java Servlet. The problem is I have to pass via POST method to a webserver a request. The content of this request is not a parameter but the body itself. So I basically send from ruby something like this: url = URI.parse(@host) req = Net::HTTP::Post.new('/WebService/WebServiceServlet') req['Content-Type'] = "text/xml" # req.basic_auth 'account', 'password' req.body = data response = Net::HTTP.start(url.host, url.port){ |http| puts http.request(req).body } Then I have to retrieve the body of this request in my servlet. I use the classic readline, so I have a string. The problem is when I have to parse it as XML: private void useXML( final String soft, final PrintWriter out) throws ParserConfigurationException, SAXException, IOException, XPathExpressionException, FileNotFoundException { DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); domFactory.setNamespaceAware(true); // never forget this! DocumentBuilder builder = domFactory.newDocumentBuilder(); Document doc = builder.parse(soft); XPathFactory factory = XPathFactory.newInstance(); XPath xpath = factory.newXPath(); XPathExpression expr = xpath.compile("//software/text()"); Object result = expr.evaluate(doc, XPathConstants.NODESET); NodeList nodes = (NodeList) result; for (int i = 0; i < nodes.getLength(); i++) { out.println(nodes.item(i).getNodeValue()); } } The problem is that builder.parse() accepts: parse(File f), parse(InputSource is), parse(InputStream is). Is there any way I can transform my xml string in an InputSource or something like that? I know it could be a dummy question but Java is not my thing, I'm forced to use it and I'm not very skilled.

  • How can I bind a simple Javascript array to an MVC3 controller action method?

    - by Sergio Tapia
    Here is the javascript code I use to create the array and send it on it's way: <script type="text/javascript" language="javascript"> $(document).ready(function () { $("#update-cart-btn").click(function() { var items = []; $(".item").each(function () { var productKey = $(this).find("input[name='item.ProductId']").val(); var productQuantity = $(this).find("input[type='text']").val(); items[productKey] = productQuantity; }); $.ajax({ type: "POST", url: "@Url.Action("UpdateCart", "Cart")", data: items, success: function () { alert("Successfully updated your cart!"); } }); }); }); </script> The items object is properly constructed with the values I need. What data type must my object be on the backend of my controller? I tried this but the variable remains null and is not bound. [Authorize] [HttpPost] public ActionResult UpdateCart(object[] items) // items remains null. { // Some magic here. return RedirectToAction("Index"); }

  • [jQuery 1.4] move one div over another

    - by Tomasz Zielinski
    I have two div elements that are twins (i.e. their dimensions and contents are identical). I want to move of those div-s over another, so that their corners are at exactly the same coordinates. What I try to do is: var offset = $('div#placeholder').offset(); $('div#overlay').css('position', 'absolute').css('left', offset.left + 'px').css('top', offset.top + 'px') -- but this causes the overlay to be exactly (or almost exactly, taking subpixel accuracy into account) 16px below the placeholder (below, i.e. overlay_top = placeholder_top + 16px). I'm aware that offset() gives position relative to the document, and position: absolute sets position relative to body element, but compensating for body offset() doesn't help much (I'm getting 8px offset, equal to margins): offset.top -= $('body').offset().top; offset.left -= $('body').offset().left; Also, compensating for body margins (in case they were different that offset() didn't help, as they were set to 8px). Does somebody know what I'm doing wrong here? UPDATE: Take a look at here - I'm getting the same result in FireFox 3.6.3 and Opera 10.10.

  • Global and local variables in my script

    - by Acorn
    I'm starting out learning javascript, and tried to write a little script that would make a grid of divs on a page. Here's the script: var tileWidth=50; var tileHeight=100; var leftPos=10; var topPos=10; var columns=10; var rows=10; var spacing=5; $('document').ready(function() { placeTiles(); }); function makeRow() { for (var i=0; i<columns; i++) { $('#canvas').append('<div class="tile" style="left:' + leftPos + 'px;top:' + topPos + 'px;"></div>'); var leftPos = leftPos + tileWidth + spacing; } } function placeTiles() { for (var i=0; i<rows; i++) { makeRow(); var topPos = topPos + tileHeight + spacing; } } At the moment, 100 <div>s get created, all with a top position of 10px and a left position of undefined (for the first <div> in the row) or NaN. What should I be doing differently? Why can't makerow() see my global leftPos variable (and all the other variables for that matter)? Thanks.

  • pass other form elements to ajax suggestion box script

    - by Alex Calder
    I paid somebody to build me a jQuery AJAX suggestion box script a while back. It works great. Now I'm trying to learn about it enough to modify it to do something different. Right now, the script that generates the suggestions just takes the query text and does the same check every time. Now, I want to be able to pass along additional info so different things are looked for with each instance of a search box. The HTML... simple, obvious. input class="suggest" name="q" type="text" autocomplete="off" / The jQuery looks like this: jQuery(document).ready(function() { $('.suggest').autocomplete( { source:'output.php', minLength:3, focus: function (event, ui) { $(event.target).val(ui.item.label); return false; } } ); [snip] } Instead of: source:'output.php', minLength:3, I'd like: source:'output.php?arg1=blah1&arg2=blah2', minLength:3, where arg1 and arg2 are passed along in the form... input class="suggest" name="q" type="text" autocomplete="off" / input type="hidden" name="arg1" value="blah1" input type="hidden" name="arg2" value="blah2" Does this make sense? Thanks guys. I know just about "this much" about OOL's and javascript, so I'm learning... Alex

  • How to set an empty value using XPath?

    - by Ricardo
    Using this xml example: <templateitem itemid="5"> <templateitemdata>%ARN%</templateitemdata> </templateitem> <templateitem itemid="6"> <templateitemdata></templateitemdata> </templateitem> I am using XPath to get and set Node values. The code I am using to get the nodes is: private static Node ***getNode***(Document doc, String XPathQuery) throws XPathExpressionException { XPath xpath = XPathFactory.newInstance().newXPath(); XPathExpression expr = xpath.compile(XPathQuery); Object result = expr.evaluate(doc, XPathConstants.NODESET); NodeList nodes = (NodeList) result; if(nodes != null && nodes.getLength() >0) return nodes.item(0); throw new XPathExpressionException("No node list found for " + XPathQuery); } To get %ARN% value: "//templateitem[@itemid=5]/templateitemdata/text()" and with the getNode method I can get the node, and then call the getNodeValue(). Besides getting that value, I would like to set templateitemdata value for the "templateitem[@itemid=6]" since its empty. But the code I use can't get the node since its empty. The result is null. Do you know a way get the node so I can set the value?

  • Can I interrupt javascript code and then continue on a keystroke?

    - by Brian Ramsay
    I am porting an old game from C to Javascript. I have run into an issue with display code where I would like to have the main game code call display methods without having to worry about how those status messages are displayed. In the original code, if the message is too long, the program just waits for the player to toggle through the messages with the spacebar and then continues. This doesn't work in javascript, because while I wait for an event, all of the other program code continues. I had thought to use a callback so that further code can execute when the player hits the designated key, but I can't see how that will be viable with a lot of calls to display.update(msg) scattered throughout the code. Can I architect things differently so the event-based, asynchronous model works, or is there some other solution that would allow me to implement a more traditional event loop? Am I making sense? Example: // this is what the original code does, but obviously doesn't work in Javascript display = { update : function(msg) { // if msg is too long // wait for user input // ok, we've got input, continue } }; // this is more javascript-y... display = { update : function(msg, when_finished) { // show part of the message $(document).addEvent('keydown', function(e) { // display the rest of the message when_finished(); }); } }; // but makes for amazingly nasty game code do_something(param, function() { // in case do_something calls display I have to // provide a callback for everything afterwards // this happens next, but what if do_the_next_thing needs to call display? // I have to wait again do_the_next_thing(param, function() { // now I have to do this again, ad infinitum } }

  • How do you get the viewport scale after pinch/zoom on an iPhone web app?

    - by Loktar
    Does anyone know how to get the size in pixels or scale value of the viewport after a user has pinched or double tapped to zoom in/out on a page in JavaScript? I've tried using window.innerWidth but I've had mixed results. Sometimes it seems to accurately give the number of pixels the viewport is showing, however, if I zoom way in on a page and then do a large pinch to zoom back out, window.innerWidth will be around 600-700 even though it is only showing ~200px of the page. The page is only 400px wide and it didn't show the checkered "you've gone too far" background you see when you zoom out beyond the page size. If I do small pinches to zoom in and out, window.innerWidth appears to work just fine. Unfortunately I can't rely on a user only making small pinch gestures :) I've also tried to use the scale property on the gesture event object, but I've found that unreliable because you don't always know the initial scale when you reload the page or use back/forward buttons to navigate to it even when using the meta tag to specify it. Ultimately, I'm trying to make an app that is aware of when a user is trying to zoom out beyond the maximum zoom level so if there is another way to do this I'm interested in hearing about it :) Here's the code I'm using to get the innerWidth: document.body.addEventListener('gestureend', function (evt) { console.log(window.innerWidth); // inaccurate when doing large pinch gestures }, false); Thanks!

  • Javascript tr click event with newly created rows

    - by yalechen
    I am very new to web development. I am currently using tablesorter jquery plugin to create a dynamic table, where the user can add and delete rows. I am having trouble with changing the background color of newly created rows upon clicking. It works fine with rows that are hard coded in html. Here is the relevant code: $(document).ready( function() { $('table.tablesorter td').click( function (event) { $(this).parent('tr').toggleClass('rowclick'); $(this).parent('tr').siblings().removeClass('rowclick'); }); } ) rowclick is a css class here: table.tablesorter tbody tr.rowclick td { background-color: #8dbdd8; } I have tried adding the following to my javascript function that adds a new row: var createClickHandler = function(newrow) { return function(event) { //alert(newrow.cells[0].childNodes[0].data); newrow.toggleClass('rowclick'); newrow.siblings().removeClass('rowclick'); }; } row.onclick = createClickHandler(row); The alert correctly displays the text in the first column of the row when I click the new row. However, my new rows do not respond to the css class. Anyone have any ideas? Thanks in advance.

  • DD_belatedPNG.js - how to access the vml object? this is for a PNG image-swap.

    - by akc
    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!
