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

    - 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.

  • javascript .push() doesn't seem to work

    - by Ankur
    I am trying to use .push to put items into a javascript array. I have created a simplified piece of code.

  • How to show a server side error message in a popup using php

    - by Fero
    Hi all, I found some of the similar questions here but they are all in C#. So kindly tell me the easiest way to show the server side error message using popup. The popup may be anything like thickbox, modalpopup etc... Here is the sample code. I didn't get the error message in the popup. <script type="text/javascript" src="thickbox/jquery-latest.js"></script> <script type="text/javascript" src="thickbox/thickbox.js"></script> <link href="thickbox/thickbox.css" rel="stylesheet" type="text/css" /> <span class="prtexterror" style="color:#FF0000;display:none;" id="hiddenModalContent" >{$error_login}</span> {literal} <script language="javascript" type="text/javascript"> $(document).ready(function() { tb_show("Please, login", "?tb_inline=true&inlineId=hiddenModalContent&height=180&width=300&modal=true", null); }); </script> {/literal} Any other ways are always welcome. thanks in advance

  • JavaScript: Double script tags in Google Analytics tracking code

    - by Tom
    This is more a curiosity question than anything else... Google instructs to add the analytics tracking code as follows: <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> try{ var pageTracker = _gat._getTracker("UA-xxxxxx-x"); pageTracker._trackPageview(); } catch(err) {} </script> I'm wondering some JS guru here could tell me why they're separating it into two script tags instead of sticking it all inside one. I know that the top part could be put in the header and the bottom part just before body tag to ensure the page loaded before it's tracked, but I'm wondering if there's something more to it. Anyone who'd know that would likely know how to separate the code into two tags anyway. I'm only asking as this is coming from the Goog and is being used by millions of sites... Thanks

  • Javascript: Onload if checkbox is checked, change li class

    - by BoDiE2003
    I have this code on javascript side: function changeSelectionStyle(id) { if(document.getElementById(id).className != 'yes'){ document.getElementById(id).className = 'yes'; } else{document.getElementById(id).className = '';} } And this on html: <ul> <li id="selectedAuthorities-4_1li" class=""> <input type="checkbox" id="selectedAuthorities-4_1" name="selectedAuthorities" value="ROLE_ADD_COMMENT_TO_CV" checked="checked" onload="changeSelectionStyle(this.id + 'li');" onclick="changeSelectionStyle(this.id + 'li'); checkFatherSelection(this.id);"> <a href="#" onclick="document.getElementById('selectedAuthorities-4_1').click(); return false;"> Agregar comentario <samp><b></b>Permite agregar comentario en el detalle.</samp> </a> </li> Well what I cant get work is when the checkbox is selected, on load, the JS should check it, and assign class="yes" to the li, here: <li id="selectedAuthorities-4_1li" class=""> What should I add to my original JS function to make that possible. Note that li ids are not static, they are dynamic, the html li id is generated.

  • On Render Callback For G+ Button

    - by Michael Robinson
    How might I go about performing an action only when a G+ button has finished rendering? Facebook allows one to do this using the following: FB.XFBML.parse(document, function() { alert('rendering done'); }); I've perused Google's documentation, but didn't see anything helpful. Currently my workaround is to monitor the G+ element until certain elements have been added, then perform my action: (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; po.onload = function() { var awaitRender = function(element) { if (element.firstChild && element.firstChild.firstChild && element.firstChild.firstChild.tagName.toUpperCase() === 'IFRAME') { alert('rendered!'); } else { window.setTimeout(function() { awaitRender(element) }, 100); } }; var buttons = document.getElementsByClassName('googleplus-button'); for(var i = 0; i < buttons.length; i++) { awaitRender(buttons[i]); } } var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })(); I'd like to know please, if there is either: A correct way one should do this for G+ buttons A better implementation that what I've hacked together above

  • How can I get contentWindow for an Object element in IE7

    - by Scott Leis
    I have a HTML object element like this: <object title="Search results as XML" standby="Loading XML document..." type="text/xml" data="/__CA25761100195585.nsf/WebPrintListingXML?OpenAgent&date1=01/06/2009" width="100%" height="100%" border="0" name="resultIFrame" id="resultIFrame" Error: could not embed search results. </object I also have this javascript function (alert() calls added for debugging): function getFrameByName(fParent,fName) { var fArray=fParent.frames; if (!fName) return; if (fArray) { if (fArray.length) { for (var i=0; i<fArray.length; i++) { alert('loop '+i); if (fArray[i]) { if (fArray[i].name==fName) return fArray[i]; } } } } var tmp=document.getElementsByName(fName); if (tmp[0]) { alert('returning '+tmp[0]); if (!(tmp[0].contentWindow)) alert('contentWindow is null'); return tmp[0].contentWindow; } } And finally, this button is meant to print the content of the Object element: <input type="button" value="Print" name="printBtn" onclick="getFrameByName(window,'resultIFrame').print();" The button works perfectly in Firefox. Opera is good enough, though it prints the main document instead of just the object. IE7 gives the following error details: Line: 57 Char: 1 Error: 'undefined' is null or not an object Line 57 is where the button's "input" tag starts in the HTML source. Thanks to the alert('contentWindow is null') call in the JS function, I know that the object I'm getting in IE has no contentWindow property. I have tried changing the object tag to an iframe tag. This changes the JS behaviour, but causes other issues such as the height attribute being ignored and the content not displaying. Sticking with an object tag, how can I get this Object's window in IE7?

  • Getting the data inside the C# web service from Jsonified string

    - by gnomixa
    In my JS I use Jquery's $ajax functions to call the web service and send the jsonified data to it. The data is in the following format: var countries = { "1A": { id: "1A", name: "Andorra" }, "2B": { id: 2B name: "Belgium" }, ..etc }; var jsonData = JSON.stringify({ data: data }); //then $ajax is called and it makes the call to the c# web service On the c# side the web service needs to unpack this data, currently it comes in as string[][] data type. How do I convert it to the format so I can refer to the properties such as .id and .name? Assuming I have a class called Sample with these properties? Thanks! EDIT: Here is my JS code: var jsonData = JSON.stringify(countries); $.ajax({ type: 'POST', url: 'http://localhost/MyService.asmx/Foo', contentType: 'application/json; charset=utf-8', data: jsonData, success: function (msg) { alert(msg.d); }, error: function (xhr, status) { switch (status) { case 404: alert('File not found'); break; case 500: alert('Server error'); break; case 0: alert('Request aborted'); break; default: alert('Unknown error ' + status); } } }); inside c# web service I have: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; using System.Data; using System.Collections; using System.IO; using System.Web.Script.Services; [WebMethod] [ScriptMethod] public string Foo(IDictionary<string, Country> countries) { return "success"; }

  • Javascript iframe caching issue

    - by Brian
    I hava an iframe which loads some javascript via javascript. In internet explorer only, this works if and only if IE has a cached copy of the javascript. This means that reloading the page (or otherwise triggering the script to run again, if it's stuck in a function or whatever) will cause this code to work, otherwise it will not. In particular, the document.write call fails to happen. Main Page: <iframe height = "200" width = "200" id = "happy"> </iframe> <script type="text/javascript"> var a = document.getElementById("happy"); scripttxt = '<a href="#" id="joy">JOY</a><'+'script type="text/javascript" src="fail.js"></'+'script>'; a.src = "about:blank"; a.contentWindow.document.open(); a.contentWindow.document.write("<h3>Preview:</h3>" + scripttxt + ""); a.contentWindow.document.close(); </script> fail.js: document.write(document.getElementById("joy")); I realize I could use conditional comments to have IE skip document.open() and document.close() in the script of Main Page, but having IE skip document.open() and document.close() feels a bit hacky (Edit)...and breaks other things in IE.

  • Client-side validation breaks in IE because of PropertyProxyValidator and ScriptManager cooperation.

    - by Eugene
    The specific of the project is in using Enterpise Library for Server side validation and jQuery for client-side validation. So I have the next simple form for example: <asp:Content ID="_mainContent" ContentPlaceHolderID="MainContent" runat="server"> <script src="../../../Scripts/jquery-1.3.2.js" type="text/javascript"></script> <script src="../../../Scripts/jquery.validate.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { $("#aspnetForm").validate({ rules: { "<%= _txtProjectName.UniqueID %>": { required: true } } }); }); </script> <asp:TextBox ID="_txtProjectName" runat="server" CssClass="textBoxWithValidator_long" /> <entlib:PropertyProxyValidator id="_validatorProjectName" runat="server" ControlToValidate="_txtProjectName" PropertyName="ProjectName" SourceTypeName="LabManagement.Project.Project" /> <asp:Button CssClass="cell_InlineElement" ID="_btnSave" runat="server" Text="Save" onclick="_btnSave_Click" Width="50px" /> <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"> </asp:ScriptManager> </asp:Content> The problem is in the next: client-side validation worked correctly before I needed to implement some AJAX.NET feature. So I have to add to the page ScriptManager (the last two lines in the code). But after that the next situation appeared: In InternetExplorer((7) - only in IE !!! - in Firefox everything works correctly) after clicking save button, if left the textbox ProjectName empty the client-side jquery validation appears but (!) the page submits to the server anyway. Some notes: If delete PropertyProxyValidator from the page - the client-side validation works correctly in IE but I need it for specific of the project. It seems that the problem is in the function WebForm_OnSubmit() that is inserted to the form after PropertyProxyValidator adding. ( ... <form name="aspnetForm" method="post" action="Project.aspx?TransType=NewProject" onsubmit="javascript:return WebForm_OnSubmit();" ...>) Could anyone help, please.

  • Javascript/Canvas/Images scaling problem in Firefox

    - by DocTiger
    I have a problem with the context2d's drawImage function. Whenever I scale an image, it gets a dark border of one pixel, which is kind of ugly. That does only happen in Firefox, not in Opera or Webkit. Is this an antialiasing problem? For hours I studied the examples and available documentation without getting rid of it... I couldn't yet try it on another computer so maybe just maybe it's an issue with the graphics hardware/drivers. I have reproduced this effect with this minimal snippet, assuming exp.jpg is sized 200x200 pixels. <html> <body> <canvas id="canvas" width="400" height="400"></canvas> </body> <script type="text/javascript" src="../../media/pinax/js/jquery-1.3.2.min.js"></script> <script type="text/javascript" > context = $('#canvas')[0].getContext('2d'); img = new Image(); img.src = "exp.jpg"; //while (!img.complete); context.drawImage(img, 2,2,199,199); context.drawImage(img, 199,2,199,199); </script> </html>

  • This pagination script is doodoo - I need a better one!

    - by ClarkSKent
    Hello, I was looking at the pagination script (posted below) and found it to be gros,s and not very good at all especially when trying to customize it. This is what the main page looks like: <?php include('config.php'); $per_page = 9; //Calculating no of pages $sql = "select * from messages"; $result = mysql_query($sql); $count = mysql_num_rows($result); $pages = ceil($count/$per_page) ?> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/ libs/jquery/1.3.0/jquery.min.js"></script> <script type="text/javascript" src="jquery_pagination.js"></script> <div id="loading" ></div> <div id="content" ></div> <ul id="pagination"> <?php //Pagination Numbers for($i=1; $i<=$pages; $i++) { echo '<li id="'.$i.'">'.$i.'</li>'; } ?> </ul> The top part of the code gets the results from the mysql db and than uses this information to display the numbers in the body of this page. I am trying to put something like this on a separate page like count_page.php and then just include it. I guess my question is, if there is a better way of doing the above with better structure. A better way to go through the db and count the results and display the appropriate numbers. The above seems messy. Thanks for any help or suggestions on this.

  • TinyMCE is glitchy/unusable in IE8

    - by Force Flow
    I'm using the jQuery version of TinyMCE 3.3.9.3 In firefox, it works fine (10 sec video depicting it in use): http://www.youtube.com/watch?v=TrAE0igfT3I In IE8 (in IE8 standards mode), I can't type or click any buttons. However, if I use ctrl+v to paste, then I can start typing, but the buttons still don't work (a 45 sec video depicting it in use): http://www.youtube.com/watch?v=iBSRlE8D8F4 The jQuery TinyMCE demo on TinyMCE's site works for me in IE8. Here's the init code: $().ready(function(){ function tinymce_focus(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#6478D7'}); } function tinymce_blur(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#93a6e1'}); } $('textarea.tinymce').tinymce({ script_url : 'JS/tinymce/tiny_mce.js', theme : "advanced", mode : "exact", invalid_elements : "b,i,iframe,font,input,textarea,select,button,form,fieldset,legend,script,noscript,object,embed,table,img,a,h1,h2,h3,h4,h5,h6", //theme options theme_advanced_buttons1 : "cut,copy,paste,pastetext,pasteword,selectall,|,undo,redo,|,cleanup,removeformat,|", theme_advanced_buttons2 : "bold,italic,underline,|,bullist,numlist,|,forecolor,backcolor,|", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "none", theme_advanced_resizing : false, //plugins plugins : "inlinepopups,paste", dialog_type : "modal", paste_auto_cleanup_on_paste : true, setup: function(ed){ ed.onInit.add(function(ed){ //check for addEventListener -- primarily supported by firefox only var edDoc = ed.getDoc(); if ("addEventListener" in edDoc){ edDoc.addEventListener("focus", function(){ tinymce_focus(); }, false); edDoc.addEventListener("blur", function(){ tinymce_blur(); }, false); } }); } }); }); Any ideas as to why it's not working in IE8? [edit]: stripping everything out of the init (leaving just script_url and theme) results in the same symptoms

  • How is a functional programming-based javascript app laid out?

    - by user321521
    I've been working with node.js for awhile on a chat app (I know, very original, but I figured it'd be a good learning project). Underscore.js provides a lot of functional programming concepts which look interesting, so I'd like to understand how a functional program in javascript would be setup. From my understanding of functional programming (which may be wrong), the whole idea is to avoid side effects, which are basically having a function which updates another variable outside of the function so something like var external; function foo() { external = 'bar'; } foo(); would be creating a side effect, correct? So as a general rule, you want to avoid disturbing variables in the global scope. Ok, so how does that work when you're dealing with objects and what not? For example, a lot of times, I'll have a constructor and an init method that initializes the object, like so: var Foo = function(initVars) { this.init(initVars); } Foo.prototype.init = function(initVars) { this.bar1 = initVars['bar1']; this.bar2 = initVars['bar2']; //.... } var myFoo = new Foo({'bar1': '1', 'bar2': '2'}); So my init method is intentionally causing side effects, but what would be a functional way to handle the same sort of situation? Also, if anyone could point me to either a python or javascript source code of a program that tries to be as functional as possible, that would also be much appreciated. I feel like I'm close to "getting it", but I'm just not quite there. Mainly I'm interested in how functional programming works with traditional OOP classes concept (or does away with it for something different if that's the case).

  • jQuery cycle floats on top of other content

    - by Angie Dubis
    I tried to replace my Flash video with a jQuery cycle. The cycle works, but the images will not stay in the editable region I placed them in. Instead they are floating on top of other content. Any ideas? This is happening on the home page of massageeducator.com There are 2 cycles on the page. “Slideshow1” and “slideshow2”. “slideshow1” works perfectly. The only thing I did differently was set up “slideshow2” as a library item since it will appear on every page, but added function code manually. I tried adding code and images via the template and had the same issue. I also tried adding both the function code and slideshow to each page instead of library item - same problem. I have both slide shows pointing to the same jquery.cycle.lite.1.0.js. Should I rename this .js file and have each cycle point to a different file? I am new to jQuery so any help is appreciated. I can't seem to post my code due to the spam filters in here!

  • W3C error doc error? Output tag browser support.

    - by ThomasReggi
    Was looking at the reference page here : http://www.w3.org/TR/html5/offline.html I copied and pasted the code on my server here in separate files. All of the pages are linked correctly but the clock won't show. Just to double check, it wasn't my "server config" I put it on jsfiddle.net here: http://jsfiddle.net/reggi/Dy8PU/. Fails: MAC / FIREFOX 3.6.13 Wins: MAC / FIREFOX 4.0.b8 Is this dummy example code? <!-- clock.html --> <!DOCTYPE HTML> <html> <head> <title>Clock</title> <script src="clock.js"></script> <link rel="stylesheet" href="clock.css"> </head> <body> <p>The time is: <output id="clock"></output></p> </body> </html> /* clock.css */ output { font: 2em sans-serif; } /* clock.js */ setTimeout(function () { document.getElementById('clock').value = new Date(); }, 1000); UPDATE: The W3C code above works on only the NEWEST Beta releases of certain browsers Below are some viable current javascript workarounds

  • Continuing JavaScript "classes" - enums within

    - by espais
    From a previous question, I have the following: So I have implemented a resource class, now I'd like to continue extending it and add all my constants and enums (or as far as JS will allow...). This is what I currently have: var resources = { // images player : new c_resource("res/player.png"), enemies : new c_resource("res/enemies.png"), tilemap : new c_resource("res/tilemap.png") }; And this is what I would like to continue to extend it to: var resources = { // images player : new c_resource("res/player.png"), enemies : new c_resource("res/enemies.png"), tilemap : new c_resource("res/tilemap.png"), // enums directions : {up:0, right:1, down:2, left:3}, speeds : {slow: 1, medium: 3, fast: 5} }; ... function enemies() { this.dir = resources.directions.down; // initialize to down } When I attempt to access resources.directions.up, my JS script goes down in a flaming pile of burning code. Are enums allowed in this context, and if not, how can I properly insert them to be used outside of a normal function? I have also tried defining them as global to a similar effect. edits: fixed the comma...that was just an error in transcribing it. When I run it in Firefox and watch the console, I get an error that says resources is undefined. The resources 'class' is defined at the top of my script, and function enemies() directly follows...so from what I understand it should still be in scope...

  • translate a PHP $string using google translator API

    - by Toni Michel Caubet
    hey there! been google'ing for a while how is the best way to translate with google translator in PHP, found very different ways converting URLS, or using Js but i want to do it only with php (or with a very simple solution JS/JQUery) example: //hopefully with $from_lan and $to_lan being like 'en','de', .. or similar function translate($from_lan, $to_lan, $text){ // do return $translated_text; } can you give me a clue? or maybe you already have this function.. my intention it's to use it only for the languages i have not already defined (or keys i haven't defined), that's why i wan it so simple, will be only temporal.. EDIT thanks for your replies we are now trying this soulutions: function auto_translate($from_lan, $to_lan, $text){ // do $json = json_decode(file_get_contents('https://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=' . urlencode($text) . '&langpair=' . $from_lan . '|' . $to_lan)); $translated_text = $json->responseData->translatedText; return $translated_text; } (there was a extra 'g' on variables for lang... anyway) it returns: works now :) i don't really understand much the function, so any idea why is not acepting the object? (now i do) OR: unction auto_translate($from_lan, $to_lan, $text){ // do // $json = json_decode(file_get_contents('https://ajax.googleapis.com/ajax/services/language/translate?v=1.0&q=' . urlencode($text) . '&langpair=' . $from_lan . '|' . $to_lan)); // $translated_text = $json['responseData']['translatedText']; error_reporting(1); require_once('GTranslate.php'); try{ $gt = new Gtranslate(); $translated_text = $gt-english_to_german($text); } catch (GTranslateException $ge) { $translated_text= $ge->getMessage(); } return $translated_text; } And this one looks great but it doesn't even gives me an error, the page won't load (error_report(1) :S) thanks in advance!

  • jQuery AJAX Redirection problem

    - by meosoft
    Hello please consider this: On page A I have a link that takes you to page B when JS is off, but when JS is on, I want to replace content on current page with content from the page B. Pages A and B are in fact the same script that is able to tell AJAX calls from regular ones and serve the content appropriately. Everything works fine, as long as there are no redirects involved. But, sometimes there is a 301 redirect and what seems to be happening is that client browser then makes a second request, which will return with a 200 OK. Only the second request is sent without a X-Requested-With header, therefore I cannot tell within my script wether it came from AJAX or not, and will send a complete page instead of just the content. I have tried checking for 301 status code in my error, success, and complete handlers but none of them worked. It seems to be handling the 301 behind the scenes. Could anyone help me with this? jQuery 1.4, PHP 5 Edit: People requested the code to this, which I didn't think was necessary but here goes: // hook up menu ajax loading $('#menu a').live("click", function(){ // update menu highlight if($(this).parents('#menu').size() > 0){ $("#menu>li").removeClass("current_page_item"); $(this).parent().addClass("current_page_item"); } // get the URL where we will be retrieving content from var url = $(this).attr('href'); window.location.hash = hash = url; $.ajax({ type: "GET", url: url, success: function(data){ // search for an ID that is only present if page is requested directly if($(data).find('#maincontent').size() > 0){ data = $(data).find('#maincontent .content-slide *').get(); } // the rest is just animating the content into view $("#scroller").html(data); $('.content-slide').each(setHeight); $('.content-slide').animate({ left: "0px" }, 1000, 'easeOutQuart', function(){ $('#home').css("left", "-760px").html(data); $('#scroller').css("left", "-760px"); $('.content-slide').each(setHeight); } ); } }); return false; });
