  • how to implement 'page break' in epub reader.

    - by ganapati
    Any idea how to implement 'page break' in epub reader? .epub is nothing but HTML pages, and epub reader renders those html pages. but i wonder how some epub readers like Adobe Digital Edition implemented page break. There,when we jump to any page, you will not find half displayed line(i.e only upper part of the letters visible and lower part will be in the next page) or half images where the other part in the next page. How to push the line to next page if i cannot display it completely in the current page?

  • Is there a difference between long-polling and using Comet

    - by Saif Bechan
    I am implementing a system where I need real-time updates. I have been looking at certain scenarios and among all was Comet. Implementing this I do not see any way this is different from traditional long-polling. In both cases you have to send a request, and then the server send a response back. In the browser you interpret the response and then you start a new request. So why should I use comet if in both cases I need to open and close connections.

  • CKEditor instance already exists

    - by jackboberg
    I am using jquery dialogs to present forms (fetched via AJAX). On some forms I am using a CKEditor for the textareas. The editor displays fine on the first load. When the user cancels the dialog, I am removing the contents so that they are loaded fresh on a later request. The issue is, once the dialog is reloaded, the CKEditor claims the editor already exists. uncaught exception: [CKEDITOR.editor] The instance "textarea_name" already exists. The API includes a method for destroying existing editors, and I have seen people claiming this is a solution: if (CKEDITOR.instances['textarea_name']) { CKEDITOR.instances['textarea_name'].destroy(); } CKEDITOR.replace('textarea_name'); This is not working for me, as I receive a new error instead: TypeError: Result of expression 'i.contentWindow' [null] is not an object. This error seems to occur on the "destroy()" rather than the "replace()". Has anyone experienced this and found a different solution? Is is possible to 're-render' the existing editor, rather than destroying and replacing it? UPDATED Here is another question dealing with the same problem, but he has provided a downloadable test case.

  • jQuery Tooltip positioning issues

    - by Nimbuz
    HTML: <a href="#" rel="tooltip-1">Open Tooltip</a> <div id="tooltip-1">Tooltip Content</div> jQuery: xOffset = $('#tooltip-1').height() + 10; yOffset = -30 ; $("a[rel=tooltip-1]").hover(function(e){ this.t = this.attr("href"); $("body").append("<p id='tooltip'>"+ this.t +"</p>"); $("#tooltip") .css("top",(e.pageY - xOffset) + "px") .css("left",(e.pageX + yOffset) + "px") .fadeIn("fast"); }, function(){ this.t = ""; $("#tooltip").remove(); }); $("a[rel=tooltip-1]").mousemove(function(e){ $("#tooltip-1") .css("top",(e.pageY - xOffset) + "px") .css("left",(e.pageX + yOffset) + "px"); }); Two Issues: Tooltip div (#tooltip-1) doesn't hide on mouseout. Since the tooltip div will always have the same ID as REL, I'd like to modify the above jQuery so that it takes target DIV ID automatically. Thanks in advance for your help.

  • Exporting data from a YUI DataTable

    - by Bears will eat you
    What's the easiest/fastest way to grab data out of a YUI DataTable and turn it into a single CSV or TSV string? I basically just want to implement a one-click way to get the entire DataTable (it should preserve the currently-applied sorting) into a form that users can paste into a spreadsheet. My DataTable can get pretty big - 5000 to 10000 rows, 5 to 10 columns - so efficiency does matter.

  • jQuery AJAX request (Rails 3) gets redirected and returns empty message body (only with SSL)!

    - by elsurudo
    I'm trying to do a manual jQuery AJAX request the following way: $("#user_plan_id").change(function() { $("#plan_container").load('/plans/' + this.value); }); I have the "rails.js" file included in my header, and a "<%= csrf_meta_tag %". I see from my log that the request IS getting to the server (although without the authenticity token... does rails.js even do this?), but the response is a 302 (Found) rather than 200, and no data actually gets rendered. Any ideas? Edit: I now see that the first request redirects, and the proper partial gets rendered on the redirect. However, the 2nd response's body (on the client-side) is still empty. I'm guessing jQuery uses the first response and doesn't have a listener set up for the redirect. How do I get around this? Also, another note: the page doing the requesting is an HTTPS page. Here is what my log says: Started GET "/plans/221168073" for 127.0.0.1 at Tue Jun 15 01:24:06 -0400 2010 Processing by PlansController#show as HTML Parameters: {"id"=>"221168073"} DEPRECATION WARNING: Using #request_uri is deprecated. Use fullpath instead. (called from ensure_proper_protocol at /Users/ernestsurudo/Sites/vidfolia/vendor/plugins/ssl_requirement/lib/ssl_requirement.rb:57) Redirected to http://vidfolia.com/plans/221168073 Completed 302 Found in 1ms It turns out that if I turn off SSL requirement for that page, it works! I still have no idea why, though. So I suppose my question is: what is the workaround?

  • jQuery, insertBefore, validation, Placement of error message

    - by Steve
    I am using insertBefore under errorplacement to add validation messages, each one below each other as I want the order of the messages to go from top to bottom. I am using a hidden input at the very bottom of a parent element in order to supply an element for the insertBefore argument. Is there a way to insert from the bottom without using the dummy hidden element? If I use absolute positioning, there is a possibility for white space, for example 3 stacked messages, the middle one missing since there is no collapsing with absolute positioning.

  • Selenium RC > how to upload file using attachFile()

    - by Saara
    hello, I am using Selenium RC with Junit framework. I am trying to upload a file using attachFile() method. attachFile: (Information collected from selenium API http://release.seleniumhq.org/selenium-remote-control/1.0-beta-2/doc/java/com/thoughtworks/selenium/Selenium.html#attachFile(java.lang.String,%20java.lang.String)) void attachFile(java.lang.String fieldLocator, java.lang.String fileLocator) Sets a file input (upload) field to the file listed in fileLocator Parameters: fieldLocator - an element locator fileLocator - a URL pointing to the specified file. Before the file can be set in the input field (fieldLocator), Selenium RC may need to transfer the file to the local machine before attaching the file in a web page form. This is common in selenium grid configurations where the RC server driving the browser is not the same machine that started the test. Supported Browsers: Firefox ("*chrome") only. Can anyone please tell me how to define "fileLocator". I am not getting which URL to be specify over here. Please give me an example if possible.

  • jQuery UI - Close Dialog When Clicked Outside

    - by Sonny
    I have a jQuery UI Dialog that gets displayed when specific elements are clicked. I would like to close the dialog if a click occurs anywhere other than on those triggering elements or the dialog itself. Here's the code for opening the dialog: $(document).ready(function() { var $field_hint = $('<div></div>') .dialog({ autoOpen: false, minHeight: 50, resizable: false, width: 375 }); $('.hint').click(function() { var $hint = $(this); $field_hint.html($hint.html()); $field_hint.dialog('option', 'position', [162, $hint.offset().top + 25]); $field_hint.dialog('option', 'title', $hint.siblings('label').html()); $field_hint.dialog('open'); }); /*$(document).click(function() { $field_hint.dialog('close'); });*/ }); If I uncomment the last part, the dialog never opens. I assume it's because the same click that opens the dialog is closing it again. Final Working Code $(document).ready(function() { var $field_hint = $('<div></div>') .dialog({ autoOpen: false, minHeight: 50, resizable: false, width: 375 }) .bind('clickoutside', function(e) { if (!$(e.target).filter('.hint').length) { $field_hint.dialog('close'); } }); $('.hint').click(function() { var $hint = $(this); $field_hint.html($hint.html()); $field_hint.dialog('option', 'position', [162, $hint.offset().top + 25]); $field_hint.dialog('option', 'title', $hint.siblings('label').html()); $field_hint.dialog('open'); }); });

  • How to make an inner shadow effect on big font ?

    - by Relax
    I want to make the effect as demonstrate on this site http://dropshadow.webvex.limebits.com/ with arguments - left:0 top:0 blur:1 opacity:1 examples:engraved font:sans serif I tried #333333 -1px -1px but seems not enough to make an inner shadow on such big font, it may be much more complex than i thought? And worse is i'm using Cufon to replace the font but Cufon doesn't support blur of text-shadow I guess maybe i should use JS to make this effect, but i doubt JS will work together with Cufon, or JS font replacement together with JS shadow maker? Any ideas?

  • Why is this simple jQuery hover event misbehaving in Internet Explorer 8?

    - by Siracuse
    I asked for help earlier on Stackoverflow involving highlighting spans with the same Class when a mouse hovers over any Span with that same Class. It is working great: http://stackoverflow.com/questions/2709686/how-can-i-add-a-border-to-all-the-elements-that-share-a-class-when-the-mouse-has $('span[class]').hover( function() { $('.' + $(this).attr('class')).css('background-color','green'); }, function() { $('.' + $(this).attr('class')).css('background-color','yellow'); } ) Here is an example of it in usage: http://dl.dropbox.com/u/638285/0utput.html However, it doesn't appear to work properly in IE8, while it DOES work in Chrome/Firefox. Here is a screenshot of it in IE8, with my mouse hovered over the " min) { min" section in the middle. As you can see, it highlighted the span that the mouse is hovering over perfectly fine. However, it has also highlighted some random spans above and below it that don't have the same class! Only the span's with the same Class as the one where the mouse is over should be highlighted green. In this screenshot, only that middle green section should be green. Here is a screenshot of it working properly in Firefox/Chrome with my mouse in the exact same position: This screenshot is correct as the span that the mouse is over (the green section) is the only one in this section that shares that class. Why is IE8 randomly green-highlighting spans when it shouldn't be (they don't share the same class) using my little jQuery snippet? Again, if you want to see it live I have it here: http://dl.dropbox.com/u/638285/0utput.html

    I'm new to Xcode and iPhone apps. I want to select an image from iPhone (camera or library) and send to php via ajax. http://wiki.phonegap.com/iPhone:-Camera-API I'm using the phonegap framework, Xcode iPhone SDK version 3.1.x. On clicking button it calls function with parameter 0 or 1, but it does not initialize camera or display the library. I checked the simulator virtual phone; there is no icon for camera, but the pictures album is there. I used the same code as in the above link. What do I do, what and how to check? any other functions to get photos using phonegap?

  • Using Jquery to get JSON objects from local file.

    - by ThoughtCrhyme
    I'm trying to get a list of JSON objects (products) from a local file using Jquery and store all the objects in a single array called allItems. The file is co-located in the same directory as the code, and it's called "allItems.json". Here's how I'm doing it now: function getAllSupportedItems(){ var allItems = new Array(); $.getJSON("allItems.json", function(data){ $.each(data.items, function(item){ allItems.push(item); }); }); return allItems; } Based on this example: http://api.jquery.com/jQuery.getJSON/

  • callback execution order in jQuery getJSON

    - by lau
    I'm trying to implement a iGoogle like dashboard interface using widgets that get their content from other sites using JSONP calls. The problem is that if the first widget that calls the "$.ajax" takes 8 seconds to get the content back, it seems that the callbacks of the other widgets will only be called after the callback of the first widget gets executed. For the user experience, it would be better if the widgets could be displayed as soon as they get the content back from the remote sites, and not wait for those that were scheduled before to complete. Is there a way I can do that?

  • JsLint 'out of scope' error

    function test(){ if(true){ var a = 5; } alert(a); } test(); I keep getting 'out of scope' errors in my JS code when I check with JsLint which make no sense to me.So I quickly created an example. Is there something actually wrong with this code piece, as the variable is eventually hoisted to the top of the function anyways.
