  • Internet Explorer treating AJAX GET request as POST request?

    - by Matt Huggins
    For some reason, only in IE (tried 7 & 8), jQuery is performing a POST request when it should be a GET. See below: function(...) { /* ... */ $.ajax({ type: 'GET', dataType: 'script', url: '/something/' + id, processData: false, data: 'old_id=' + oldId, success:function(data) { alert(data); } }); /* ... */ } All browsers properly GET, but IE is performing a POST. Why?

  • Hoe to convert a JSON array of paths to images stored on a server into a javaScript array to display them? Using AJAX

    - by MichaelF
    I need for html file/ ajax code to take the JSON message and store the PATHS as a javaScript array. Then my buildImage function can display the first image in the array. I'm new to AJAX and believe my misunderstanding lies within the converting of the JSON to Javascript. I'm confused also about if my code creates a JSON array or object or either. I might need also to download a library to my app to understand JSON? Below is a PHP file loading the paths of the images. I believe json ecode is converting the PHP Array in a Json message. <?php include("mysqlconnect.php"); $select_query = "SELECT `ImagesPath` FROM `offerstbl` ORDER by `ImagesId` DESC"; $sql = mysql_query($select_query) or die(mysql_error()); $data = array(); while($row = mysql_fetch_array($sql,MYSQL_BOTH)){ $data[] = $row['ImagesPath']; } echo $images = json_encode($data); ?> Below is the script in is going to be loaded on an Cordova app. <!DOCTYPE html> <html> <head> <link rel="stylesheet" href="css/styles.css"> <link rel="stylesheet" href="css/cascading.css"> <script> function importJson(str) { // console.log(typeof xmlhttp.responseText); if (str=="") { document.getElementById("content").innerHTML=""; return; } if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else { // code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4) { //var images = JSON.parse(xmlhttp.responseText); document.getElementById("content").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","http://server/content.php"); xmlhttp.send(); } function buildImage(src) { var img = document.createElement('img') img.src = src alert("1"); document.getElementById('content').appendChild(img); } for (var i = 0; i < images.length; i++) { buildImage(images[i]); } </script> </head> <body onload= "importJson();"> <div class="contents" id="content" ></div> <img src="img/logo.png" height="10px" width="10px" onload= "buildImage();"> </body>

  • Will AJAX cause my site to have a high bounce % and hurt my search ratings?

    - by Cryo
    I'm building an art gallery website that updates its images via AJAX, for those who have javascript enabled, rather than request multiple page loads. I assume this will appear as though my site has a high bounce percentage. I understand that search engines will not be able to index dynamic content, but will such a misinterpreted bounce rate hurt my search engine ratings, even if I have many return visitors?

  • Is dynamic HTML layout good from an SEO perspective?

    - by sll
    Just wondering whether dynamically built HTML layout is fine from SEO perspectives? So let's assume e-commerce engine and its most popular page - products catalog. So 90% of the page is built using AJAX and MVVM library knockoutjs which builds HTML on the fly on the client side. So how search bots would parse such content? Is it fine indexed and would be such effective as server-side built HTML pages from the SEO perspectives?

  • Mercurial not receiving push

    - by Jeffrey04
    I have a mercurial web-frontend (hgwebdir.cgi) installed on a server, and an installation of nginx was installed in front of it as a reverse proxy to the web-frontend as my friend suggested. However, whenever a large changeset is pushed (via a script), it would fail. I found an issue ticket @google-code that describe similar problem, and there is a solution that says (#39) So the server side answer is: don't send the 401 back early. Be as slow/dumb as 'hg serve' and make the hg client send the bundle twice. How do I do that? My current nginx config location /repo/testdomain.com { rewrite ^(.*) http://bpj.kkr.gov.my$1/hgwebdir.cgi; } location /repo/testdomain.com/ { rewrite ^(.*) http://bpj.kkr.gov.my$1hgwebdir.cgi; } location /repo/testdomain.com/hgwebdir.cgi { proxy_pass http://localhost:81/repo/testdomain.com/hgwebdir.cgi; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_buffering on; client_max_body_size 4096M; proxy_read_timeout 30000; proxy_send_timeout 30000; } From the access log we keep seeing 408 entries incoming.ip.address - - [18/Nov/2009:08:29:31 +0800] "POST /repo/testdomain.com/hgwebdir.cgi/example_repository?cmd=unbundle&heads=73121b2b6159afc47cc3a028060902883d5b1e74 HTTP/1.1" 408 0 "-" "mercurial/proto-1.0" incoming.ip.address - - [18/Nov/2009:08:37:14 +0800] "POST /repo/testdomain.com/hgwebdir.cgi/example_repository?cmd=unbundle&heads=73121b2b6159afc47cc3a028060902883d5b1e74 HTTP/1.1" 408 0 "-" "mercurial/proto-1.0" Is there anything else I can do on the server because solving it on the server side is preferable :/ Further Findings Bitbucket seems to have this solved ( Check liquidhg bitbucket project and the Diagnosis wiki page ) on the server side, can't find the config anywhere though :/ What happens next varies depending on your server. Some servers refuse the BODY, simplying closing the pipe from the client and causing Mercurial to fail. Some, like Apache (at least the way I configure it, and that could be part of the problem) and nginx (they way BitBucket.org configures it), accept the BODY, though it may take a few retries. Bottom line: if Mercurial doesn't fail the push, it sends the changeset data at least once to a server that has already told it it lacks credentials (more on this at Blame). Assuming Mercurial is still running, it resends the "unbundle" request and data, this time with authentication. Finally, Apache accepts the data successfully. Nginx, OTOH, at least under BitBucket's configuration, seems to reassemble the previous body (the one that lacked authentication) and somehow keep Mercurial from re-sending the whole body.

  • Monitoring JSON requests sent/received from the browser?

    - by Uwe Keim
    Having a website that generates and receives JSON requests via AJAX, I failed to find a tool that shows me live the communication including the content of the JSON calls. I thought that the Google Chrome developer tools or the IE 9 developer tools do have such a feature, but again, I failed. Searching Google, I failed too. So my question is: Is there a client-side tool to monitor the content of JSON requests that a website sends to the server?

  • Google crawling the site but refusing to index dynamic content

    - by Omeoe
    I am trying to get Google to index an AJAX site (davidelifestyle.com). It's crawlable with JavaScript turned off and I have also recently implemented _escaped_content_ snapshot mechanism but all that's indexed is a home page and PDF files that are not directly available from the home page. Also when I use Fetch as Google in Webmaster Tools, it downloads the dynamic page but does not index it ("Submit to Index" just reloads the page). Any ideas what might be wrong?

  • How do I make my hosting detect _escaped_fragment_ and fetch the corresponding HTML? [on hold]

    - by Eric
    I have an AJAX site and I'm using shebangs (#!) in my urls with the intention of then providing the correct HTML versions when google bots replace the #! with _escaped_fragment_. How do I go about routing/proxying/redirecting the url with _escaped_fragment_ to the corresponding html pages? I can't find documentation on this part of the process specifically, and my first thought was that I should be using a 301 or 302 redirect, but I was told that wasn't the case, albeit not given any more info.

  • XMLHttpRequest not working, trying to test database connection [closed]

    - by Frederick Marcoux
    I'm currently creating my own CMS for personnal use but I'm blocked at a code. I'm trying to make a installation script but the AJAX request to test if database works, doesn't work... There's my JS code: function testDB() { "use strict"; var host = document.getElementById('host').value; var username = document.getElementById('username').value; var password = document.getElementById('password').value; var db = document.getElementById('db_name').value; var xmlhttp = new XMLHttpRequest(); var url = "test_db.php"; var params = "host="+host+"&username="+username+"&password="+password+"&db="+db; xmlhttp.open("POST", url, true); xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", params.length); xmlhttp.setRequestHeader("Connection", "close"); xmlhttp.send(params); $('#loader').removeAttr('style'); if (xmlhttp.responseText !== '') { if (xmlhttp.readyState===4 && xmlhttp.status===200) { $('#next').removeAttr('disabled'); $('#test').attr('disabled', 'disabled'); $('#test').text('Connection Successful!'); $('#test').addClass('btn-success'); $('#login').addClass('success'); $('#login1').addClass('success'); $('#db').addClass('success'); $('#loader').attr('style', 'display: none;'); } else { $('#next').attr('disabled', 'disabled'); $('#test').removeClass('btn-success'); $('#test').removeAttr('disabled'); $('#test').text('Test Connection'); $('#login').removeClass('success'); $('#login1').removeClass('success'); $('#db').removeClass('success'); $('#loader').attr('style', 'display: none;'); } } else { $('#next').attr('disabled', 'disabled'); $('#next').attr('disabled', 'disabled'); $('#test').removeClass('btn-success'); $('#test').removeAttr('disabled'); $('#test').text('Test Connection'); $('#login').removeClass('success'); $('#login1').removeClass('success'); $('#db').removeClass('success'); $('#loader').attr('style', 'display: none;'); } } And there's my PHP code: <?php $link = mysql_connect($_POST['host'], $_POST['username'], $_POST['password']); if (!$link) { echo ''; } else { if (mysql_select_db($_POST['db'])) { echo 'Connection Successful!'; } else { echo ''; } } mysql_close($link); ?> I don't know why it doesn't work but I tried with JQuery $.ajax, $.get, $.post but nothing work...

  • Best approach to creating self-updating content - i.e. chat rooms, shoutboxes and so on

    - by Anonymous -
    The only way I can think of to have a shoutbox or similar element update itself when somebody posts a new 'shout' and it needs to be loaded in everyone else's browsers is to have Javascript check every x seconds for any updates... This could get a bit resource intensive though I expect if many people were to leave their browsers open on the page, idling. Is this the only way or am I missing something? I've prefer to stick to only html, css, javascript (AJAX) and php.

  • How to cache dynamic javascript/jquery/ajax/json content with Akamai

    - by Starfs
    Trying to wrap my head around how things are cached on a CDN and it is new territory for me. In the document we received about sending in environment requests, it says "Dynamically-generated content will not benefit much from EdgeSuite". I feel like this is a simplified statement and there has to be a way to make it so you cache dynamically generated content if the tools are configured correctly. The site we are working with runs off a wordpress database, and uses javascript and ajax to build the pages, based on the json objects that php scripts have generated. The process - user's browser this URL, browser talks to edgesuite tools which will have cached certain pre-defined elements, and then requests from the host web server anything that is not cached, once edgesuite has compiled a combination of the two, it sends that information back to the browser. Can we not simply cache all json objects (and of course images, js, css) and therefore the web browser never has to hit the host server's database, at which point in essence, we have cached our dynamic content? Does anyone have any pointers on the most efficient configuration for this type of system -- Akamai/CDN -- to served javascript/ajax/json generated pages that ideally already hit pre-cached json data? Any and all feedback is welcome!

  • Building Interactive User Interfaces with Microsoft ASP.NET AJAX: Refreshing An UpdatePanel With Jav

    The ASP.NET AJAX UpdatePanel provides a quick and easy way to implement a snappier, AJAX-based user interface in an ASP.NET WebForm. In a nutshell, UpdatePanels allow page developers to refresh selected parts of the page (instead of refreshing the entire page). Typically, an UpdatePanel contains user interface elements that would normally trigger a full page postback - controls like Buttons or DropDownLists that have their AutoPostBack property set to True. Such controls, when placed inside an UpdatePanel, cause a partial page postback to occur. On a partial page postback only the contents of the UpdatePanel are refreshed, avoiding the "flash" of having the entire page reloaded. (For a more in-depth look at the UpdatePanel control, refer back to the Using the UpdatePanel installment in this article series.) Triggering a partial page postback refreshes the contents within an UpdatePanel, but what if you want to refresh an UpdatePanel's contents via JavaScript? Ideally, the UpdatePanel would have a client-side function named something like Refresh that could be called from script to perform a partial page postback and refresh the UpdatePanel. Unfortunately, no such function exists. Instead, you have to write script that triggers a partial page postback for the UpdatePanel you want to refresh. This article looks at how to accomplish this using just a single line of markup/script and includes a working demo you can download and try out for yourself. Read on to learn more!

  • How can i supply an AntiForgeryToken when posting JSON data using $.ajax ?

    - by HerbalMart
    I am using the code as below of this post: First i will an fill array variable with the correct values for the controller action. Using the code below i think it should be very straigtforward by just adding the following line to the javascript: data["__RequestVerificationToken"] = $('[name=__RequestVerificationToken]').val(); The <%= Html.AntiForgeryToken() %> is at his right place and the action has a [ValidateAntiForgeryToken] But my controller action keeps saying: "Invalid forgery token" What am i doing wrong here? Code data["fiscalyear"] = fiscalyear; data["subgeography"] = $(list).parent().find('input[name=subGeography]').val(); data["territories"] = new Array(); $(items).each(function() { data["territories"].push($(this).find('input[name=territory]').val()); }); if (url != null) { $.ajax( { dataType: 'JSON', contentType: 'application/json; charset=utf-8', url: url, type: 'POST', context: document.body, data: JSON.stringify(data), success: function() { refresh(); } }); }

  • Create Math Game with PHP, Ajax, Jquery

    - by Sambucasun
    I am developing a website where user can create their own game which can be joined by other users as well. It's a simple maths game which will shoot equations based on time or count specified. I want that moment user create a game, it will be listed in "current Games" section. Other users can check out the list and select the game to join. After game is created, creater should have a screen which should be having his name with display pic. Now gradually as others start joining the game, list should updated automatically. Once enough users are there i will start the game. The same list should be displayed to other users who join the game. Once game is over all will be displayed a summary list. I have gone through couple of threads but could not get clear idea. Do I need to use comet or other technology to create such game or simple PHP, Ajax or Jquery will suffice ? Also I want my website should be mobile compatible so i am designing it in html5. If i create this game using just Ajax then will there be any performance issue while playing through mobile. I am not much experienced so just need guidance for what should be appropriate or use for my requirement.
