  • Overlaying one div over another, but not knowing the size of the div

    - by andyuk
    I'm trying to lay one div over another. This is really simple if you know the dimensions of the div. Solved here: How to overlay one div over another div So, here is my HTML: <div class="container"> <div class="overlay"></div> <div class="content"></div> </div> In my case, I don't know the exact dimensions of the "content" or "container" div. This is because I don't have control over any of the content in the div (we are making our app extensible for 3rd party developers). See my example on jsFiddle The overlay should cover the content entirely. Width 100% and Height 100%. However, this does not work because in my example I positioned the overlay absolutely. One solution is to use JavaScript to get the size of the content div and then set the size of the overlay. I don't like this solution much since if image sizes are not specified, you need to wait until images are loaded and recalculate the size of the div. Is there any way of solving this problem in CSS?

    I have the following page public partial class GenericOfflineCommentary : OfflineFactsheetBase { } where OfflineFactsheetBase is defined as public class OfflineFactsheetBase : System.Web.UI.Page { public OfflineFactsheetBase() { this.Load += new EventHandler(this.Page_Load); this.PreInit += new EventHandler(this.Page_PreInit); } protected void Page_PreInit(object sender, EventArgs e) { if (Request.QueryString["data"] != null) { this.PageData = StringCompressor.DecompressString(Request.QueryString["data"]); this.ExtractPageData(); } } } OfflineFactsheetBase has the following virtual method: public virtual void ExtractPageData() { // get stuff relevant to all pages that impmement OfflineFactsheetBase } which is implemented in all pages that impmement OfflineFactsheetBase as follows: public partial class GenericOfflineCommentary : OfflineFactsheetBase { public override void ExtractPageData() { // get stuff relevant to an OfflineCommentary page. } } Currently, only GenericOfflineCommentary's ExtractPageData() is firing. How can I modify this to first run OfflineFactsheetBase's ExtractPageData() and then GenericOfflineCommentary's?

  • Count number of given object in a list with LINQ

    - by Aaginor
    I have a list which can contain multiple occurrences of the same object. Now I need to count, how often the given object is contained in this list. int count = 0; foreach (IMyObject item in myList) if (item == object2Count) count++; I am sure that this can be done nicer with LINQ, but LINQ is still a mystery to me. My first question is: How would I count the objects via LINQ and the second question: Will this LINQ version be slower or faster? I am using a ObservableCollection and the number of items in the list is usally rather small ... usally not more then 20. Thanks in advance, Frank

  • Why Can't Businesses Upgrade their Browsers from IE6/IE7?

    - by viatropos
    I have read lots these past few weeks on IE6, seeing if it was really that bad to make it look right. I have just learned HTML and CSS this past year so I've been spoiled to start with basically CSS3 and HTML5, and I can do some really cool stuff super fast. I'm no IE6 master and I don't have years of experience with IE. So I thought it'd take a little time to figure out all the hacks to IE6/7 discovered and just implement them. But it's way harder than that (or maybe just way too much work). I'd have to either completely rebuild my design using "Internet Explorer 'Principles'", or cut out a lot of the neat things I could do using more recent technologies. For a million and one other reasons, everyone who builds things online seems to think IE should die. My question is, why can't businesses upgrade their browsers? When I work with businesses, they almost always resist the first time I ask, but 5 seconds later I'll show them what it looks like on my computer and talk about how great the latest stuff is (how much more secure later browser are, all the famous IE security cases, how much smoother and faster they new browsers are, how the IE team has basically missed the boat entirely, how much smoother business processes run, etc.), and they get excited! And within a few seconds they're up and running with Chrome or something. So can businesses not upgrade for some reasons? What are the reasons a business cannot upgrade? The main reason I think of is because they have an old version of windows. But a) wasn't there a legal case against this? and b) somebody must have figured out how to install Chrome or Firefox on ancient versions of Windows by now.

  • Serialize an object to string

    - by Vaccano
    I have the following method to save an Object to a file: // Save an object out to the disk public static void SerializeObject<T>(this T toSerialize, String filename) { XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType()); TextWriter textWriter = new StreamWriter(filename); xmlSerializer.Serialize(textWriter, toSerialize); textWriter.Close(); } I confess I did not write it (I only converted it to a extension method that took a type parameter). Now I need it to give the xml back to me as a string (rather than save it to a file). I am looking into it, but I have not figured it out yet. I thought this might be really easy for someone familiar with these objects. If not I will figure it out eventually.

  • Symfony: Pass an object from another module to a form

    - by djcloud23
    I have a symfony project and I have one model, which for this example I will name Boat. From the Boat's showSuccess page, I would like to make a link to another model's form page. For this example we will call it Ticket. When they click on the link, I would like for the Boat object to be passed to the Ticket form because I have to display some of that specific Boat's fields (title, price, etc) on the Ticket form page (newSuccess.php). I guess my question is, how do I pass an object (as a variable) to another model's "new" form page. I have looked everywhere and I can't seem to find an answer that works for me. Thank you!

  • Building html structure in php or javascript?

    - by Adam
    I've been doing a lot of ajax calls and using the returned data to build html with javascript. However, I've noticed some people are returning the constructed html in the ajax calls since they're doing it all in php. What is the preferred method? I have a bunch of stuff already using javascript, so I guess I would prefer not changing everything to use just php. But, I'm assuming php would be more "secure."? The following is what I've been doing: $main_frag = $("<div class='order-container'/>"); $contact_frag = $("<div class='group'><div class='line-data'>Name: "+data.name+"</div><div class='line-data'>Email: "+data.email+"</div><div class='line-data'>Phone: "+data.phone+"</div></div>"); $address_frag = $("<div class='group'><div class='line-data'>Address 1: "+data.address_one+"</div><div class='line-data'>Address 2: "+address2+"</div><div class='line-data'>City: "+data.city+"</div><div class='line-data'>Province: "+data.province+"</div><div class='line-data'>Postal Code: "+data.postal+"</div></div>"); etc.. I just want to hear the opinions of the community.

  • Updating table row by given id with jQuery

    - by fabrik
    Hello all! I need to update a specific table row (via tr id="unique_key") after a successful AJAX call. HTML fragment: <a name=\"p{$product_id}\" class=\"tr{$product_id}\"></a> <tr id="p{product_id}" class="item-row"> <td><h3>{product_id}</h3><a rel="facebox" href="ajax_url">{product_name}</a></td> <td>{image_information}</td> <td>{image_sortiment}</td> <td>{product_status}</td> </tr> Javascript: // AJAX Call success: function(msg){ $('#p' + prod_id).remove(); $('.tr' + prod_id).after(msg); $('#p' + prod_id + ' a[rel*=facebox]').facebox(); } ... What happens: The table row removed Anchors grouped into one single row (not before their <tr>'s) so my 'hook' disappears AJAX result inserted over the whole table (after my 'hook' but still a wrong place) What's wrong with my idea? How can i force jQuery to 'overwrite' the required table row?

  • Making a Delete and Reply button in Jquery

    - by Branko Ostojic
    this is my second post on the website. Of all other sites i tried, this one gave the most accurate and useful information! I'm in a bit of a trouble with buttons, i have a task to make an inbox and to add a "reply" and "delete" button into every instance of the message. I was indeed wandering if there is a better way to do that than forcing the HTML code into the script, because every message is dynamically generated. Any help and/or suggestions would be very appreciated!(The objects are called from a JSON file). $(document).ready(function(){ $.getJSON('public/js/data.json', function(json){ $.each(json.data, function(i, data){ var output = ''; if(data.from.id != '234' && data.from.name != 'Alan Ford'){ $("#inbox").append( output += '<div class="post">'+ '<div class="h1">'+data.from.name+' - '+data.subject+'</div>'+ //this gives the name of the person who sent the message and the subject '<div class="content">'+data.message_formatted+'</div>'+ //The content of the message //buttons should be squeezed left of the date //this gives the date of the message sent '<div class="time">'+data.date_sent_formatted.formatted+'</div>'+ '</div>' ); }}); }); }); var date_sent=convertToDateTime(); function delete_message(id){ console.log('Delete message with id: '+id); } function reply_message(id, sender){ console.log('Message id: '+id); console.log('Reply to: '+sender); } The complete code in the JSFiddle . Just copy/pasted!

  • Alternate colors on click with jQuery

    - by Jace Cotton
    I'm sure there is a simple solution to this, and I'm sure this is a duplicate question, though I have been unable to solve my solution particularly because I don't really know how to phrase it in order to search for other questions/solutions, so I'm coming here hoping for some help. Basically, I have spans with classes that assigns a background-color property, and inside those spans are words. I have three of these spans, and each time a user clicks on a span I want the class to change (thus changing the background color and inner text). HTML: <span class="alternate"> <span class="blue showing">Lorem</span> <span class="green">Ipsum</span> <span class="red">Dolor</span> </span> CSS: .alternate span { display : none } .alternate .showing { display : inline } .blue { background : blue } .green { background : green } .red { background : red } jQuery: $(".alternate span").each(function() { $(this).on("click", function() { $(this).removeClass("showing"); $(this).next().addClass("showing"); }); }); This solution works great using $.next until I get to the third click, whereafter .showing is removed, and is not added since there are no more $.next options. How do I, after getting to the last-child, add .showing to the first-child and then start over? I have tried various options including if($(".alternate span:last-child").hasClass("showing")) { etc. etc. }, and I attempted to use an array and for loop though I failed to make it work. Newb question, I know, but I can't seem to solve this so as a last resort I'm coming here.

  • How to check the correct radio button.

    - by MrW
    I have a Table containing some information that I need. All these rows also contains a column with a radio button in it so that the user is suppose to be able to check one of the rows as default. When I'm bringing the data back from the DB and want to select the one that's currentlly the default one. <% foreach (var item in (IEnumerable<Locale>) ViewData["Locales"]) { %> <tr> <td> <%= Html.Encode(item.Language.Name) %> </td> <td> <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%= item.Default == false ? "false" : "true" %>" /> </td> I've also tried to do this: <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%=item.Default == false ? "" : "checked" %>" /> but nothing seems to do the right thing. I always end up with having the last row in checked, which it isn't for sure.

  • What techniques do you use for emitting data from the server that will solely be used in client side scripts?

    - by chuck
    Hi all, I never found an optimal solution for this problem so I am hoping that some of you out there have a few solutions. Let's say I need to render out a list of checkboxes and each checkbox has a set of additional data that goes with it. This data will be used purely in the context of javascript and jquery. My usual strategy is to render this data in hidden fields that are grouped in the same container as the checkbox. My rendered HTML will look something like this: <div> <input type="checkbox" /> <input type="hidden" class="genreId" /> <input type="hidden" class="titleId" /> </div> My only problem with this is that the data in the hidden fields get posted to the server when the form is submitted. For small amounts of data, this is fine. However, I frequently work with large datasets and a large amount of data is needlessly transferred. UPDATE: Before submitting this post, I just saw that I can add a "DISABLED" attribute to my input element to suppress the submission of data. Is this pretty much the best approach that I can take? Thanks

  • simulate what native object is not exist

    - by Naitro
    Here is the situation: I have checking on existing class like: ('Promise' in window) // true/false` And I wanna force return false or true on it, can I do it? Yes, I can check it by some other way, like ` window.Promise = undefined; window.Promise === undefined; Or something like this, but can I somehow delete this object or simulate something for 'in' operator? I check specification and v8 code, there is 'in' operator just call 'HasProperty' operator, which realization on c++.. I know 'hack' with faking toString/valueOf methods: obj = { toString: function(){ return 'myName'; } }, obj2 = {}; obj2[obj] = 1; // Object {myName: 1} May be I can use it in some way? But, as I send string 'Promise' I can't just fake it like this way.. may be exist some way to fake 'HasProperty'?

  • Iterating Through a jQuery Object Array

    - by DeltaFox
    I know this has been asked and answered a couple times already, but I'm still confused about how to reference the current object when iterating over a jQuery array. For example, the following code gives me the error "TypeError: genH3Array[i].next is not a function". What is the right way to reference the current array object? var genH3Array = $('#Generation_II').parent(); genH3Array.push($('#Generation_III').parent());; genH3Array.push($('#Generation_IV').parent()) $.each(genH3Array, function(i, value) { if(genH3Array[i].next().attr("align") == "center") { genH3Array[i].next().next().next().insertBefore(heading.next()) } genH3Array[i].next().next().insertBefore(heading.next()) genH3Array[i].next().insertBefore(heading.next()) })

  • Getting hold of a reference to the object created by JOptionPane static methods

    - by user548240
    Hi, I wonder if it is possible to get hold of a reference to the (JDialog?) object created by one of those static methods of JOptionPane (e.g. showMessageDialog)? I intend to modify the position where the dialog appears on the screen. More specifically, I want the dialog to appear at the top-left corner of the main app window, instead of the centre of the window by default. So having a reference to the object would enable me to use setLocation to achieve the desired effect... Any suggestion would be appreciated! Thanks!

  • Passing object through WCF so that server receives client changes

    - by cvig
    I would like to set up a WCF service so that any changes a client makes to an object I send them are also reflected on the server side. For example, if Assembly A has the following... namespace AssemblyA { public class Person { public string FirstName { get; set; } public string LastName { get; set; } } [ServiceContract] public interface IServer { [OperationContract] Person GetPerson(); } } And Assembly B references Assembly A... using AssemblyA; namespace AssemblyB { class Program { static void Main(string[] args) { <snip> IServer server = factory.CreateChannel(); Person person = server.GetPerson(); person.FirstName = "Kilroy"; person.LastName = "WuzHere"; } } } What is the easiest/best way to make it so that the service's copy of the Person object also reflects the changes that the client makes? Is this even possible?
