  • Problems with display of UTF-8 encoded content from a DB

    - by LookUp Webmaster
    Dear members of the Stackoverflow community, We are developing a web application using the Zend Framework, and we are facing some encoding issues that we hope you might help us solve. The situation goes something like this: There are certain tables on a MySQL database that need to be displayed as html. Because the site is designed using the Spanish language, the database contains some characters like "á" or "ñ". Our internal policy is to set all the encodings as UTF-8, including all the databases and the tables. The problem is, that when we retrieve the content from the DB, some characters are displayed as question marks. We are out of ideas. These are all the things that we have already tried and double-checked: 1. The SQL file from which we load all the data is properly UTF-8 encoded. 2. The SQL is loaded through phpmyadmin (which is configured as UTF-8), and the resulting tables are displayed properly. 3. The netbeans environment used for coding is also set as UTF-8. The weird thing is that all the content that is hard-coded either as php or html is displayed properly. Only the values that are extracted from the database have issues. Any ideas? Thank you very much.

  • SCJP Book, IO section: Is this a typo or is there a reason it would look like this?

    - by iamchuckb
    My question is about line 4, where the new PrintWriter is created with the constructor taking the FileWriter fw as a parameter. I don't understand the use of chaining the BufferedWriter bw to FileWriter if it isn't used later on in the actual writing. Can Java apply chaining in a way that bw still somehow affects the rest of the program? 16. try { 17. FileWriter fw = new FileWriter(test); 18. BufferedWriter bw = new BufferedWriter(fw, 1024); 19. PrintWriter out = new PrintWriter(fw); 20. out.println("<html><body><h1>"); 21. out.println(args[0]); 22. out.println("</h1></body></html>"); 23. out.close(); 24. bw.close(); 25. fw.close(); 26. }catch(IOException e) { 27. e.printStackTrace(); 28. } I think it is probably a typo and they meant to use bw as the parameter for PrintWriter out but like the title says, I'm new to this. Thanks to all in advance.

  • PHP header location redirect causing 500 Internal Server error

    - by Globalz
    Hi, I I keep getting a 500 Internal Server Error when the script below reaches the header('location:php_email_thankyou.php'). Im not sure what is causing this, as I can place the header expression before or after the if statements and it works fine. In firebug it mentions a GET request for the php_email_thankyou.php page not sure if that means anything... <?php ini_set('display_errors', 'On'); error_reporting(E_ALL | E_STRICT); include('php/cl/cl_val.php'); $val = new Validate; $print_errors = false; if (isset($_POST['email(email)'])){ if(isset($_SERVER['HTTP_X_REQUESTED_WITH'])) { $validation = $val->clean($_POST); if (isset($validation['send'])) { header('location:php_email_thankyou.php'); exit(); } else { print json_encode($validation); exit(); } } else { $validation = $val->clean($_POST); } } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> Thanks heaps!

  • Binding mousemove within mousedown function with jQuery

    - by colinjameswebb
    I am trying to bind a mousemove event to a div when the left mousebutton is down, and unbind when it is released. This code should be fairly self-explainatory. function handleMouseDown(e, sbar){ if (e.button == 0){ console.log(sbar); //firebug sbar.bind('mousemove', function(event){ handleMouseMove(event, sbar); }); } } function handleMouseUp(e, sbar){ sbar.unbind('mousemove'); } function handleMouseMove(e, sbar){ // not sure it this will work yet, but unimportant $(".position").html(e.pageX); } $(document).ready(function (){ var statusbar = $(".statusbar"); statusbar.mousedown(function(event){ handleMouseDown(event, this); }); statusbar.mouseup(function(event){ handleMouseUp(event, this); }); }); The important part of the HTML looks like this <div id="main"> <div class="statusbar"> <p class="position"></p> </div> </div> Firebug says that the bind methods are undefined on the variable sbar within handleMouseDown and handleMouseUp. The firebug console prints out <div class="statusbar"> for the line commented //firebug. I'm doing something wrong, probably when binding the mousedown and mouseup... but what?! I'm using jQuery v1.4.2, if that helps?

  • Embedding XSL Stylesheet into XML

    I have the following XML: <?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="http://www.fakedomain.com/sally.xsl"?> And the following content in sally.xsl: <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <html> <body> <xsl:for-each select="documentcollection/document"> <p> <xsl:for-each select="rss/channel/item"> <xsl:value-of select="title"/><br /> <xsl:value-of select="description"/><br /> <xsl:value-of select="link"/><br /> </xsl:for-each> </p> </xsl:for-each> </body> </html> </xsl:template> </xsl:stylesheet> However, the browser displays the XML as though the XSL line is not present. Do you know why the browser is ignoring the XSL stylesheet? Is the style sheet wrong? Thanks

  • how to return an error in an Ajax scenario from ASP.NET MVC action

    - by mohang
    I am using ASP.NET MVC with jquery. I have the following MVC Action that returns a partial page on Success. On Application Error, I am not sure what to send it for correctly handling it at the client side. public ActionResult LoadFilterSet(int filterSetId) { try { BreadCrumbManager bcManager = this.ResetBreadCrumbManager(this.BreadCrumbManagerID); GeneralHelper.LoadBreadCrumbManager(bcManager, filterSetId); ViewData["BreadCrumbManager"] = bcManager; return View("LoadFilterSet"); } catch (Exception ex) { return Content(""); } } Following is my jquery ajax call. Notice that I am checking for the data length to make sure there are no errors. Please suggest me a better way of doing this. $.ajax({ type: "GET", dataType: "html", async: true, data: ({ filterSetId: selectedId }), url: link, contentType: "text/html; charset=utf-8", success: function(data, textStatus) { if (data.length > 0) { // Clear the local filters first. clearLocalFilters(); $('td.selected-filters table.filters-display').append(data); } } });

  • How to change CSS color values in real-time off a javascript slider?

    - by bflora
    I'm making a page where the user gets a javascript slider that goes from 0 to 100 and can use it to set the opacity of a div on the page. I want the opacity of that div to change in real-time as they work the slider. I've not done this before. What's the best approach? There cursor in the slider displays the slider's current value as you move it. It seems to be that I just need to find a way to display that value in any arbitrary other place on the page so I can display it in the style settings for the div. The .js file that generates the slider has a line that (I think) is setting the current value in the cursor: $(this).children(".ui-slider-handle", context).html(parseInt(settings[index]['default'])); TO get this changing number to display somewhere else at the same time, do I just need to add a div somewhere and then add a line like this? $("#newDivId").children(".ui-slider-handle", context).html(parseInt(settings[index]['default'])); That seems like it would give me the number showing up in a div. How then would I get it into a form I could put into the style settings for a div? If this was a php variable, I would do something like this, style="opacity:<?php print $value ?>;" What would be the .js equivalent?

  • Django ManyToMany Membership errors making associations

    - by jmitchel3
    I'm trying to have a "member admin" in which they have hundreds of members in the group. These members can be in several groups. Admins can remove access for the member ideally in the view. I'm having trouble just creating the group. I used a ManytoManyField to get started. Ideally, the "member admin" would be able to either select existing Users OR it would be able to Add/Invite new ones via email address. Here's what I have: #views.py def membership(request): group = Group.objects.all().filter(user=request.user) GroupFormSet = modelformset_factory(Group, form=MembershipForm) if request.method == 'POST': formset = GroupFormSet(request.POST, request.FILES, queryset=group) if formset.is_valid(): formset.save(commit=False) for form in formset: form.instance.user = request.user formset.save() return render_to_response('formset.html', locals(), context_instance=RequestContext(request)) else: formset= GroupFormSet(queryset=group) return render_to_response('formset.html', locals(), context_instance=RequestContext(request)) #models.py class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField(User, related_name='community_members', through='Membership') user = models.ForeignKey(User, related_name='community_creator', null=True) def __unicode__(self): return self.name class Membership(models.Model): member = models.ForeignKey(User, related_name='user_membership', blank=True, null=True) group = models.ForeignKey(Group, related_name='community_membership', blank=True, null=True) date_joined = models.DateField(auto_now=True, blank=True, null=True) class Meta: unique_together = ('member', 'group') Any ideas? Thank you for your help.

On click, the button submits data to a php file and then changes text and blurs according to the response from php file. The blur function and change text function in col5 is working well. But the change text function in button got really buggy. The button text should change accordingly. the text of button "Activate" should change to "Inactivate" and the text of button "Inactivate" should change to "Activate" on click / successful submission.. This is not working.. Below is the php file code <?php $id = $_POST[id]; if($id=="DataA1"){ echo "ACTIVATED"; } if($id=="DataB1"){ echo "ACTIVATED"; } if($id=="DataE1"){ echo "ACTIVATED"; } if($id=="DataC1"){ echo "INACTIVATED"; } if($id=="DataD1"){ echo "INACTIVATED"; } ?> Thanks in advance.. :) blasteralfred

  • What is the simplest way to implement multithreading in c# to existing code

    - by Kaeso
    I have already implemented a functionnal application that parses 26 pages of html all at once to produce an xml file with data contained on the web pages. I would need to implement a thread so that this method can work in the background without causing my app to seems unresponsive. Secondly, I have another function that is decoupled from the first one which compares two xml files to produce a third one and then transform this third xml file to produce an html page using XSLT. This would have to be on a thread, where I can click Cancel to stop the thread whithout crashing the app. What is the easiest best way to do this using WPF forms in VS 2010 ? I have chosen to use the BackgroundWorker. BackgroundWorker implementation: public partial class MainWindow : Window { private BackgroundWorker bw = new BackgroundWorker(); public MainWindow() { InitializeComponent(); bw.WorkerReportsProgress = true; bw.DoWork += new DoWorkEventHandler(bw_DoWork); bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorker1_RunWorkerCompleted); } private void Window_Loaded(object sender, RoutedEventArgs e) { this.LoadFiles(); } private void btnCompare_Click(object sender, EventArgs e) { if (bw.IsBusy != true) { progressBar2.IsIndeterminate = true; // Start the asynchronous operation. bw.RunWorkerAsync(); } } private void bw_DoWork(object sender, DoWorkEventArgs e) { StatsProcessor proc = new StatsProcessor(); if (lstStatsBox1.SelectedItem != null) if (lstStatsBox2.SelectedItem != null) proc.CompareStats(lstStatsBox1.SelectedItem.ToString(), lstStatsBox2.SelectedItem.ToString()); } private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { progressBar2.IsIndeterminate = false; progressBar2.Value = 100; } I have started with the bgworker solution, but it seems that the bw_DoWork method is never called when btnCompare is clicked, I must be doing something wrong... I am new to threads.

  • Why Backbone.js isn't binding my event

    - by Saif Bechan
    I have a router like this, as main entry point: window.AppRouter = Backbone.Router.extend({ routes: { '': 'login' }, login: function(){ userLoginView = new UserLoginView(); } }); var appRouter = new AppRouter; Backbone.history.start({pushState: true}); I have a model/collection/view like this: window.User = Backbone.Model.extend({}); window.Users = Backbone.Collection.extend({ model: User }); window.UserLoginView = Backbone.View.extend({ events: { 'click #login-button': 'loginAction' }, initialize: function(){ _.bindAll(this, 'render', 'loginAction'); }, loginAction: function(){ var uid = $("#login-username").val(); var pwd = $("#login-password").val(); var user = new User({uid:uid, pwd:pwd}); } }); And body of my HTML looks like this: <form action="#" method="POST" id="login-form"> <p> <label for="login-username">username</label> <input type="text" id="login-username" autofocus /> </p> <p> <label for="login-password">password</label> <input type="password" id="login-password" /> </p> <a id="login-button" href="#">Inloggen</a> </form> Note: The HTML comes from Node.js using express.js, should I maybe wait for a document ready event somewhere? Edit: I have tried this, create the view when ready, did not solve the problem. $(function(){ userLoginView = new UserLoginView(); });

  • passing data from a servlet to javascript code in an Ajax application ?

    - by A.S al-shammari
    I have a simple jsp/servlet application and I want to add AJAX feature to this app. I use JQuery , but it doesn't matter what javascript framework I use. This is my code: <script type="text/javascript"> function callbackFunction(data){ $('#content').html(data); } $('document').ready(function(){ $('#x').click(function() { $.post('/ajax_2/servlet',callbackFunction) }); }); </script> <body> <a href="#" id="x">Increase it</a> <div id="content"></div> </body> </html> Servlet HttpSession session = request.getSession(); Integer myInteger = (Integer)session.getAttribute("myInteger"); if(myInteger == null) myInteger = new Integer(0); else myInteger = new Integer(myInteger+1); session.setAttribute("myInteger", myInteger); response.getWriter().println(myInteger); The Question: I use out.print to transfer data from a servlet to javascript code (ajax code) , but If I have a complex structure such as Vector of Object or something like this , what is the best way to transfer the data? what about an XML file , JSON ? Is there any special jsp/servlets library to transfer data from a servlet to ajax application ? How can I parse this data in callbackFunction ?

  • Give More Prominence To DIV or <P> That Is After Floating DIV

    - by Aahan Krish
    Consider this HTML: <div id="entry-content"> <div id="my-300px-ad">AD CODE HERE</div> <p><img src="file.jpg" alt="file" /></p> <p>SOME TEXT</p> <p>SOME MORE TEXT</p> </div> Now, consider that the div#my-300px-ad is floating right. Would it be possible for me to have the image in the next paragraph show up before the ad so that the TEXT in its following paragraphs can wrap around the ad? For example, like this: Why so...? The thing is, due to various reasons (including Google) I want to avoid placing an ad in BETWEEN the post's content. CSS only I am sure that something like this would be possible with some JavaScript code. But I am looking for a CSS-based solution only. (Cross-browser compatibility, = IE8) Please note that ONLY the CSS of div#my-300px-ad can be changed. Nothing else should be touched as this is not a static HTML page, besides they are articles. PS: It was hard to frame a one-line question for this. Please feel free to edit the question's title if it can be made more clear.

  • jquery ajaxstart ajaxstop show hide

    - by user1630583
    As usually seemingly simple things take days to resolve, maybe someone could point me to a solution but after 2 days I give up on the following problem; In html, in a form I have a button that is supposed to trigger loading of data through ajax call: <button type="" class="btn" onclick="getData(); return false;">Show Data</button> in javascript: $(document).ajaxStart(function() { $("#qloader").show(); }).ajaxStop(function() { $("#qloader").hide('slow'); });? and in html div with id qloader is defined with 100% width and height and spinner centered as the background, z-index above other: <div id="qloader" class="myLoader" >&nbsp;</div> Now, when page loads, ajax call is executed to get initial data, qloader div is brought up and it shows the spinner - animated, after ajax call finishes, qloader is hidden by ajaxStop. Next, when I click on a button (show data) to initiate another ajax call, ajaxStart is triggered, but it does not show qloader, it waits until ajaxStop is triggered and then in a blink of eye it shows qloader and hides it. I suspected that ajaxStart is not executed, so I put alert before $("#qloader").show(), then alert would be displayed and after that qloader WOULD be displayed BUT spinner animation would be suspended - no spinning, and after ajaxStop it would get hidden. Without alert in ajaxStart trigger, in subsequent ajax calls div is not shown until just before ajaxStop is triggered. It works fine for the first ajax call, but for subsequent ajax call triggered by click on form button it does not work. Any idea what is wrong with this setup?

  • Why is this Javascript that writes out a Google Ad not displaying properly on the iPhone?

    - by Dave M G
    I have this Javacsript code that checks to see if there is a DIV named "google-ad", and if there is, it writes in a the necessary code to display the Google Ad. This works great in browsers like Firefox, Chrome, Safari on Mac, and Android. However, when I bundle this code with Adobe's Phonegap Build, and deploy it to iPhones, it behaves strangely. It launches a browser window displaying just the Google Ad alone. In order to keep using my app, every time I change a page and a new Google Ad is loaded, I have to close the browser window to get back to the app. Why is this code launching browser windows outside of my Phonegap app on iPhone? if(document.getElementById("google-ad") && document.getElementById("google-ad") !== null && document.getElementById("google-ad") !== "undefined") { if(userStatus.status == 0) { document.getElementById("centre").style.padding = "137px 0 12px 0"; document.getElementById("header-container").style.margin = "-138px 0 0 0"; document.getElementById("header-container").style.height = "132px"; document.getElementById("header-username").style.top = "52px"; document.getElementById("google-ad").style.height = "50px"; document.getElementById("google-ad").style.width = "320px"; document.getElementById("google-ad").style.backgroundColor = "#f0ebff"; document.getElementById("google-ad").style.display = "block"; window["google_ad_client"] = 'ca-pub-0000000000000000'; window["google_ad_slot"] = "00000000"; window["google_ad_width"] = 320; window["google_ad_height"] = 50; window.adcontainer = document.getElementById('google-ad'); window.adhtml = ''; function mywrite(html) { adhtml += html; adcontainer.innerHTML = adhtml; }; document.write_ = document.write; document.write = mywrite; script = document.createElement('script'); script.src='http://pagead2.googlesyndication.com/pagead/show_ads.js'; script.type='text/javascript'; document.body.appendChild(script); }

  • CSS Clearing Floats

    - by Frank
    I'm making more of an effort to separate my html structure from presentation, but sometimes when I look at the complexity of the hacks or workarounds to make things work cross-browser, I'm amazed at huge collective waste of productive hours that are put into this. As I understand it, floats were never created for creating layouts, but because many layouts need a footer, that's how they're often being used. To clear the floats, you can add an empty div that clears both sides (div class="clear"). That is simple and works cross browser, but it adds "non-semantic" html rather than solving the presentation problem within the CSS. I realize this, but after looking at all of the solutions with their benefits and drawbacks, it seems to make more sense to go with the empty div (predictable behavior across browsers), rather than create separate stylesheets, including various css hacks and workarounds, etc. which would also need to change as CSS evolves. Is it o.k. to do this as long as you do understand what you're doing and why you're doing it? Or is it better to find the CSS workarounds, hacks and separate structure from presentation at all costs, even when the CSS presentation tools provided are not evolved to the point where they can handle such basic layout issues?

    Setup -- Create a simple COM addin through DOTNET/C# that does nothing but sleep on the current thread for 5 seconds. namespace ComTest { [ComVisible(true)] [ProgId("ComTester.Tester")] [Guid("D4D0BF9C-C169-4e5f-B28B-AFA194B29340")] [ClassInterface(ClassInterfaceType.AutoDual)] public class Tester { [STAThread()] public string Test() { System.Threading.Thread.Sleep(5000); return DateTime.Now.ToString(); } } } From an ASP page, call the test component: <%@ Language=VBScript %> <%option explicit%> <%response.Buffer=false%> <% dim test set test = CreateObject("ComTester.Tester") %> <HTML> <HEAD></HEAD> <BODY> <% Response.Write(test.Test()) set test = nothing %> </BODY> </HTML> When run on a windows 2003 server, the test.asp page blocks ALL OTHER threads in the site while the COM components sleeps. How can I create a COM component for ASP that does not block all ASP worker threads?

  • Delivering activity feed items in a moderately scalable way

    - by sotangochips
    The application I'm working on has an activity feed where each user can see their friends' activity (much like Facebook). I'm looking for a moderately scalable way to show a given users' activity stream on the fly. I say 'moderately' because I'm looking to do this with just a database (Postgresql) and maybe memcached. For instance, I want this solution to scale to 200k users each with 100 friends. Currently, there is a master activity table that stores the rendered html for the given activity (Jim added a friend, George installed an application, etc.). This master activity table keeps the source user, the html, and a timestamp. Then, there's a separate ('join') table that simply keeps a pointer to the person who should see this activity in their friend feed, and a pointer to the object in the main activity table. So, if I have 100 friends, and I do 3 activities, then the join table will then grow to 300 items. Clearly this table will grow very quickly. It has the nice property, though, that fetching activity to show to a user takes a single (relatively) inexpensive query. The other option is to just keep the main activity table and query it by saying something like: select * from activity where source_user in (1, 2, 44, 2423, ... my friend list) This has the disadvantage that you're querying for users who may never be active, and as your friend list grows, this query can get slower and slower. I see the pros and the cons of both sides, but I'm wondering if some SO folks might help me weigh the options and suggest one way or they other. I'm also open to other solutions, though I'd like to keep it simple and not install something like CouchDB, etc. Many thanks!

  • SSRS 2008 - Sending report as email

    - by Mozy
    Hi all, What I want to do is render a SSRS 2008 report as HTML (actually MHTML) and send that as the body in an email. Has anyone done this? I've almost got it (I think) but I seem to have a encoding problem. The email shows up as what looks like some sort of base64 encoding. Like this: MIME-Version: 1.0 Content-Type: multipart/related; boundary="----=_NextPart_01C35DB7.4B204430" X-MSSQLRS-ProducerVersion: V10.0.2531.0 This is a multi-part message in MIME format. ------=_NextPart_01C35DB7.4B204430 Content-ID: Content-Disposition: inline; filename="FollowUpNotification" Content-Type: text/html; name="FollowUpNotification"; charset="utf-8" Content-Transfer-Encoding: base64 PCFET0NUWVBFIEhUTUwgUFVCTElDICItLy9XM0MvL0RURCBIVE1MIDQuMDEgVHJhbnNp... Any ideas on what I'm missing? Here is a code snippet: myMail.BodyEncoding = System.Text.Encoding.UTF8; myMail.IsBodyHtml = true; WebClient client = new WebClient(); System.Net.NetworkCredential repAuthenticationInfo = new System.Net.NetworkCredential(@"username", @"password"); client.Credentials = repAuthenticationInfo; client.Encoding = System.Text.Encoding.UTF8; string messageBody = client.DownloadString( "http://<<reportserver>>&rs%3aFormat=MHTML&Parameter=" + Parameter); myMail.Body = messageBody;

  • Reverse geocode street name and city as text

    - by Taylor Satula
    Hello, I have been having some trouble finding a good way to output just the street name and city as text (Infinite Loop, Cupertino shown here) that can be displayed in my iPhone app. This needs to be able to dynamically change as you change streets and city. I don't have the slightest idea of how to do this, I hope someone can help. I have attached a very rough image of what I am trying to acheave. I have found this (http://code.google.com/apis/maps/documentation/javascript/services.html#Geocoding) for google maps about how to reverse geocode using javascript, but what I do not understand is how this would be done in a iPhone development setting. I work in web design and I see how it would be done in HTML but I am very new to iPhone development and don't have the slightest clue of how it would be done here. If someone could spell out how to do this I would be extremely grateful. I cannot seem to find what I am looking for by searching Google.

  • Why would certain browsers request all pages on my ASP.Net Web site twice?

    - by Deane
    Firefox is issuing duplicate requests to my ASP.Net web site. It will request a page, get the response, then immediately issue the same request again (well, almost the same -- see below). This happens on every page of this particular Web site (but not any others). IE does not do this, but Chrome also does this. I have confirmed that there is no Location header in the response, and no Javascript or meta tag in the page which would cause the page to be re-requested (if any of these were true, IE would be re-requesting pages as well). I have confirmed this behavior on multiple Firefox installs on multiple machines. Versions vary, but all are 3.x. The only difference between the two requests is the Accepts header. For the first request, it looks like this: Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 For the second request, it looks like this: Accept: */* The Content-Type response header in all cases is: Content-Type: text/html; charset=utf-8 Something else odd -- even though Firefox requests the page twice, it uses the first response and discards the second. I put a counter on a page that increments with every request. I can watch the responses come back (via the Charles proxy). Firefox will get a "1" the first time, and a "2" the second time. Yet it will display the "1," for some reason. Chrome exhibits this exact same behavior. I suspect it's a protocol-level issue, given the difference in Accepts header, but I've never seen this before.

  • Updating an input value with Jquery

    - by Evan
    I have a form with a few fields, one of which should be updated based on the value of another. The value of the first is POSTed to another URL, and the returned value should be used to fill the second field. Here's the code: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script> function lookup(rid) { $.get("/handler?rid=" + $("input#rid").val(), function(update_rid){ $("#name").val(html(update_rid)); }) } </script> <form name="new_alert"> <input type="text" name="rid" id="rid" onkeyup="lookup(this.value);"> <br /> <input type="text" name="name" id="name"> </form> The POST works fine, and the correct data is returned from /hander, which I confirmed by making a test and filling it using $("#testdiv").html(update_rid); So it seems like the problem is in the way I'm trying to update the value, but I can't get past that.

  • Problem uploading app to google app engine

    - by Oberon
    I'm having problems uploading an app to the google-app-engine from my work place. I believe the problem is related to proxy, because I do not see the same problem when following the same procedure from home. (I do not specify HTTP_PROXY from home). These are the commands I run: HTTP_PROXY=http://proxy.<thehostname>.com:8080 HTTP_PROXY=https://proxy.<thehostname>.com:8080 appcfg.py --insecure update myappfolder When running the commands I get prompted for email and password, as expected, but after that it immediately exits with this errormessage: Error 302: --- begin server output --- <HTML> <HEAD> <TITLE>Moved Temporarily</TITLE> </HEAD> <BODY BGCOLOR="#FFFFFF" TEXT="#000000"> <H1>Moved Temporarily</H1> The document has moved <A HREF="https://www.google.com/accounts/ClientLogin">here</A>. </BODY> </HTML> --- end server output --- Note: I added the --insecure option because else it gave a warning of missing ssl module. Any idea how to solve or workaround this problem?
