    - by Pradyut Bhattacharya
    Hi I have a page which has a img holder with the html: - <img src="someimage.jpeg" alt="image" class="show_image"/> Now i m updating the image with jquery using the code... $('.show_image').attr('src', 'anotherimage.jpeg'); Now its working fine but i want to show the users the image is being loaded and may wait as the image size may be huge... Is there any method in jquery to get the information of percent loaded(bytes read/remaining) or if the image load is complete... Also how can i place a div over the image placeholder such that the div can fade the image(opacity:0.8) and add some text over the div as loading or something thanks

  • Displaying Google Calendar event data on FullCalendar

    - by aurealus
    I am using Google Calendar as a storage engine for a calendar system I am building, however, I am using a single Google user account with multiple calendars, i.e. each user on my system has their own calendar within the one user account. I'm able to create a calendar per user just fine, but I would like to have FullCalendar retrieve the events for display purposes, without manually getting the magic cookie url from Google Calendar settings. I would like to be able to retrieve it programmatically or 'proxy' the feed via an authenticated call to get event data that I'm doing in Django. $('#calendar').fullCalendar({ events: $.fullCalendar.gcalFeed( "http://www.google.com/calendar_url/" <-- or /my/event/feed/url ) });

  • jqGrid local date manipulation; problem with row ids when deleting and adding new rows

    - by Sam
    I'm using jqGrid as a client side grid input, allowing the user to input multiple records before POSTing all the data back at once. I'm having a problem where if the user has added a few records (say 3 ) the id's for the records will be 1,2,3. if the user deletes record 2, you're left with 1 and 3 for the id of the records. When the user now adds a new records, jqGrid assigns that records the id 3 again since it just seems to count the total records and increments it by one for the new record. This causes problems when selecting rows as now the row id's are 1, 3 and 3. Does anyone know how to access the row ids of records as I could probably use the afterSubmit event and reassign the row id's increasing from 1. ( so after i delete row id 2, this will set the other row id's to 1 and 2) Any other suggestions to solve this problem? Thanks

  • Store a long string into mult array

    - by QLiu
    Hello All, I have a long string arrays, which looks like that var callinfo_data=new Array( "1300 135 604#<b>Monday - Friday: 9:00 a.m. to 5:30 p.m. AEST</b>", //Australia .. "0844000040#<b>lunedì-venerdì ore 10:00 - 17:00 CET</b>", //Switzerland (it) "212 356 9707#<b>Hafta içi her gün: 10:00 - 18:00</b>", //Turkey "08451610009#<b>Monday - Friday: 9:00 a.m. to 6:30 p.m. GMT</b>", //UK "866 486 6866#<b>Monday - Friday: 7:00 a.m. to 11:00 p.m. EST</b><br />Saturday: 9:00 a.m. to 8:00 p.m. EST", //USA "+31208501004#<b>Monday - Friday: 9:00 a.m. to 7:30 p.m. GMT+1</b>", //other countries " # "); As you see, it contact Phone number and open time. I can use split to separet them into info=callinfo_data[n].split("#"); two sections, And then i can represent them in HTML like "<div id ='phoneNumber'>"+info[0]+"</div><div id='openTime'>"+info[1]+"</div>" But my display phone number function will read the cookie variables, and then select the right contact info to display. Like, phone=callinfo_data[2].split("#"); if (locale == 'UK') details = phone[0]+ build_dropdown(locale); else if (locale == 'fr') details = 'French Contact Details<br>'+build_dropdown(locale); else if (locale == 'be') details = 'Belgian Contact Details<br>'+ build_dropdown(locale); else details = 'Unknown Contact Detail'; writeContactInfo(details); My questions are how I can build a function to load phone number and time based on my cookie variables, UK in a smart way. I can hard code everything, but i think it is too silly. I have to write a long code like: phone1= allinfo_data[0].split("#"); phone1= allinfo_data[1].split("#"); ... etc Second questions, how can I load this long arrays into easy access multi arrays? Thank you Regards, Qing

  • How can I detect when a file download has completed in ASP.NET?

    - by Alexis
    I have a popup window that displays "Please wait while your file is being downloaded". This popup also executes the code below to start the file download. How can I close the popup window once the file download has completed? I need some way to detect that the file download has completed so I can call self.close() to close this popup. System.Web.HttpContext.Current.Response.ClearContent(); System.Web.HttpContext.Current.Response.Clear(); System.Web.HttpContext.Current.Response.ClearHeaders(); System.Web.HttpContext.Current.Response.ContentType = fileObject.ContentType; System.Web.HttpContext.Current.Response.AppendHeader("Content-Disposition", string.Concat("attachment; filename=", fileObject.FileName)); System.Web.HttpContext.Current.Response.WriteFile(fileObject.FilePath); Response.Flush(); Response.End();

  • Drawing half of a Bezier path in Raphael

    - by Fibericon
    Let's say I have a cubic Bezier path as follows (formatted for use with the Raphael path function): M55 246S55 247 55 248 Just an example. This was taken from my drawing application, where I use the cursor to draw a line when the user holds the mouse button down, kind of like a pencil or marker. I'm using jquery's mousemove event to draw the line between two points every time the user moves the mouse. There is another (the reference point) that is taken before the line is drawn, so that the Bezier curve can be created. Here's my question: is it possible to make Raphael only draw half of a given path? I'm aware of the getSubpath() function, but if my understanding of Bezier curves is correct, it would be rather difficult to calculate the second argument. The problem with the animate function is that it creates double lines (that is, it creates the curved line that I want, and the boxy line around it which should not be shown, possibly because the mouse is being moved faster than the animation can handle). Of course, if my approach itself is flawed in some way (or my understanding of the possible solutions), I'd like to hear it. Any help would be appreciated.

  • ajax response byte size

    - by Alex Pacurar
    Im using jQuery's getJSONP and I want to log the duration of the call and the size of the response to be able to have some statistics about the usage of my application. This is a cross domain ajax call, so I need to use JSONP, but as the JSONP call is not done with an XMLHttpRequest object, the complete callback from jquery's ajax doesnt pass the response content. So my question is how to get the response size (content lenght) from a JSONP call. $.ajaxSetup( { complete:function(x,e) { log(x.responseText.length, x.responseText); } } here x is a XMLHttpRequest object for a JSON call , but for JSONP call is undefined.

  • Create an autocompleter like the Facebook status update

    - by Terw
    Hello I'm trying to create a div with contenteditable like the Facebook status update. Then I mean I want to show an autocomplete box when the user have written @. How would you do that. Currently I'm just playing with keypress and check if the keycode = 64. Somehow that works, but it doesn't validate if there's a space before the alfa, or if the user has unfocused the box, then focused it again. Any ideas? Or do you know about any plugin that works something like that? Tnx

  • Problem with adding and removing classes with jQuery when hovering over a list item.

    - by Andrew
    I want to add a class to a list item when I hover over it, and then remove it and add it to a different list item if a different list item is hovered over. Here's what I tried: jQuery - $(document).ready(function() { $("#results").text("Tournaments"); $("#Tournaments").addClass("box-active"); $("#box ul li").hover(function() { var show = $(this).attr('id'); $("#results").text(show); $("#box ul li").each(function() { $(this).removeClass("box-active"); }); $("#box ul li#" + show).addClass("box-active"); }); }); HTML - <div id="box"> <ul> <li id="Tournaments">Tournaments</li> <li id="Join">Join</li> <li id="Forums">Forums</li> <li id="GameBattles">GameBattles</li> <li id="Practice">Practice</li> </ul> <p>Hovering over: <span id="results"></span></p> </div> When I hover over an item, it changes the class, but if I hover over I different one it removes the class over the item I first hovered over, but doesn't add the class to the new item I'm hovering over. Not sure why, and any help would be appreciated.

  • How to handle empty return from getJSON

    - by Gee
    Alright so I have a php script which gets results from a DB, and to get those results I'm using a jQuery script to pull the results via getJSON. It works perfectly but now I want to do something if the php script returns no results (empty). I tried: $.getJSON('path/to/script'), {parameter:parameter}, function(data){ if (data) { alert('Result'); } else { alert('Empty); } }); But it's no good. I've tried different things like if (data.length) but still nothing. I've noticed that if there is no returned data the callback will never fire at all. So if that's the case, how do I handle a empty return?

  • Is it possible to use 2 versions of jQuery on the same page?

    - by Ben McCormack
    NOTE: I know similar questions have already been asked here and here, but I'm looking for additional clarification as to how to make this work. I'm adding functionality to an existing web site that is already using an older version of the jQuery library (1.1.3.1). I've been writing my added functionality against the newest version of the jQuery library (1.4.2). I've tested the website using only the newer version of jQuery and it breaks functionality, so now I'm looking at using both versions on the same page. How is this possible? What do I need to do in my code to specify that I'm using one version of jQuery instead of another? For example, I'll put <script> tags for both versions of jQuery in the header of my page, but what do I need to do so that I know for sure in my calling code that I'm calling one version of the library or another? Maybe something like this: //Put some code here to specify a variable that will be using the newer //version of jquery: var $NEW = jQuery.theNewestVersion(); //Now when I use $NEW, I'll know it's the newest version and won't //conflict with the older version. $NEW('#personName').text('Ben'); //And when I use the original $ in code, or simply 'jquery', I'll know //it's the older version. $('#personName').doSomethingWithTheOlderVersion();

  • Mobile safari - suppress Unsupported Protocol alert

    - by Juriy
    Hello guys, I'm creating a website for iPhone and i use the native app (cliqcliq Quickpick) to upload photos. I use the script like the following to check if the application is installed. The basic idea is to send user to a custom url, if application is there it is launched, if it is not there the url should be ignored and user is taken to App Store. Below is the script: window.launchQuickpic = function() { var start = new Date(); setTimeout(function() { if (new Date() - start > 2000) { return; } window.location = 'http://www.cliqcliq.com/quickpic/install/'; }, 1000); var getParams = [...]; window.location = 'vquickpic://?' + getParams.join('&'); }; If the native app is not installed I'm getting the alert box saying that Safari does not recognize the custom url. After user clicks "ok" it works as it is supposed to. But the alert is reeealy annoying. I've tried to surround the window.location= code with try/catch. Didn't help.

  • Disabling Firefox spell checking in iframe-based text editors

    - by Piotr Sobczyk
    There is a lot of info around about how to disable spell checking in html textarea element by using spellcheck='false'. However to have text area with more advanced capabilities, one must use iframe with designMode = "on" (see e.g. this page, this is a way that RichTextArea is implemented in GWT) and I couldn't find a single post on that topic. It turns out that Firefox detects such advanced text areas and enables its spell checking in them. You can see it live by visiting this page from Firefox and entering some content to text field. If you inspect this code, you'll see no textarea tag, yet FF spell checking is still active. The only way I managed to disable it was setting designMode to off but... I need it to be on. The question is: Is there any possibility to disable spell checking in such cases, without setting designMode = "off"?
