  • All site interaction through a single page

    - by Jacques Wolfghang
    Hi there I have an idea for a site where there would be no refreshing and all interactions take place via AJAX. The page would load with central space, where all interaction would take place. If a user clicked on a link, the page would request it via AJAX and replace the rectangle's content with the link content. The idea is effectively an AJAX implemented iframe. Are there any disadvantages with this approach? Does anyone have any suggestions or thoughts on the idea? Thank You for your time Note: I am sorry if it is not clear or hard to understand, English is not my mother tongue. If there is anything you would like made clearer, please comment and I will try my best to make it understood.

  • Browser loading strategy, <head>...<body>

    - by Bin Chen
    I am inspecting some interesting behaviors of browser, I don't know it's in standard or not. If I put everythin inside <head></head>, the browser will only begin to render the page after all the resouces in head is retrieved. So I am thinking that put as little as possible things into head is one of the important website optimization techniques, is it right? My question is: If I put script/css in body or other parts of the html, how can I know that script has been loaded successfully so that I will not be calling a undefined function?

  • Creating a loading screen in HTML5

    - by espais
    I am having some issues finding a decent tutorial for generating a loading style screen with regards to HTML5. To be quite honest I'm not sure exactly where to begin... My project is essentially a simple HTML5 game, where I'll be loading in various sprite sheets and tilesets. They'll be reasonably small, but I'd like to show a little loading spinner instead of a blank screen while all the resources are loaded. Much appreciated if somebody could point me in the right direction, be it decent links or code samples to get me going...my Google-fu is lacking today! For clarification, I need to figure out how to load the resources themselves, as opposed to finding a spinner. For instance, how to calculate that X% has loaded.

  • Debugging Post Request with Chrome Dev Tools

    - by benek
    I am trying to use Chrome Dev for debugging the following Angular post request : $http.post("http://picjboss.puma.lan:8880/fluxpousse/api/flow/createOrUpdateHeader", flowHeader) After running the statement with right-click / evaluate, I can see the post in the network panel with a pending state. How can I get the result or "commit" the request and leave easily this "pending" state from the dev console ? I am not yet very familiar with JS callbacks, some code is expected. Thanks. EDIT I have tried to run from the console : $scope.$apply(function(){$http.post("http://picjboss.puma.lan:8880/fluxpousse/api/flow/createOrUpdateHeader", flowHeader).success(function(data){console.log("error "+data)}).error(function(data){console.log("error "+data)})}) It returns : undefined EDIT The post I am trying to solve generate an HTTP 400.

  • Making JSON Feed Work Server to Server

    - by Oscar Godson
    I have a JSON feed (which I don't directly control, I have to ask the server admins to update it), that is returning NULL, or otherwise not working when I try to access it from another server. The actual feed works fine, but I can't get it to work like a normal API. Why can I use Flickr, WhitePages, Twitter, etc's JSON APIs, but for: http://portlandoregon.gov/shared/cfm/json.cfm It returns NULL in the browser when using JS. If I call it on the same server, it's fine though. If this is a server issue, what do I ask the admins to change, and if this is a local (browser) based issue, what am I doing wrong for this one feed that works for every other JSON API?

  • Wait until image loads before performing function

    - by Steven
    I'm trying to create a simple portfolio page. I have a list of thumbs and an image. When you click on a thumb, the image will change. When a thumbnail is clicked, I'd like to have the image fade out, wait until the image is loaded, then fade back in. The problem I have right now is that some of the images are pretty big, so it fades out, then fades back in immediately, sometimes while the image is still loading. I'd like to avoid using setTimeout, since sometimes an image will load faster or slower than the time I set. Here's my code: $(function() { $('img#image').attr("src", $('ul#thumbs li:first img').attr("src")); $('ul#thumbs li img').click(function() { $('img#image').fadeOut(700); var src = $(this).attr("src"); $('img#image').attr("src", src); $('img#image').fadeIn(700); }); }); <img id="image" src="" alt="" /> <ul id="thumbs"> <li><img src="/images/thumb1.png" /></li> <li><img src="/images/thumb2.png" /></li> <li><img src="/images/thumb3.png" /></li> </ul>

  • POST parameters strangely parsed inside phantomjs

    - by user61629
    I am working with PHP/CURL and would like to send POST data to my phantomjs script, by setting the postfields array below: In my php controller I have: $data=array('first' => 'John', 'last' => 'Smith'); $url='http://localhost:7788/'; $output = $this->my_model->get_data($url,$data); In my php model I have: public function get_data($url,$postFieldArray) { $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)"); curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_POSTFIELDS, $postFieldArray); curl_setopt($ch, CURLOPT_URL, $url); $output = curl_exec($ch); In my phantomJS script that I am running locally I have: // import the webserver module, and create a server var server = require('webserver').create(); var port = require('system').env.PORT || 7788; console.log("Start Application"); console.log("Listen port " + port); // Create serever and listen port server.listen(port, function(request, response) { // Print some information Just for debbug console.log("We got some requset !!!"); console.log("request method: ", request.method); // request.method POST or GET if(request.method == 'POST' ){ console.log("POST params should be next: "); console.log("POST params: ",request.post); exit; } I first start and run the phantomjs script (myscript.js) from the command line, then I run my php script. The output is: $ phantomjs.exe myscript.js Start Application Listen port 7788 null We got some requset !!! request method: POST POST params should be next: POST params: ------------------------------e70d439800f9 Content-Disposition: form-data; name="first" John ------------------------------e70d439800f9 Content-Disposition: form-data; name="last" Smith ------------------------------e70d439800f9-- I'm confused about the the output. I was expecting something more like: first' => 'John', 'last' => 'Smith Can someone explain why it looks this way? How can I parse the request.post object to assign to variables inside myscript.js

  • Trouble decoding JSON string with PHP

    - by Anthony
    I'm trying to send an array of objects from JS to PHP using JSON. I have an array of players as follows: var player; var players = new Array(); //loop for number of players player = new Object(); player.id = theID; players[i] = player; Then my AJAX call looks like this: JSONplayers = JSON.stringify(players); $.ajax({ type: "POST", url: "php/ajax_send_players.php", data: { "players" : JSONplayers } On the PHP side the decode function looks like this $players = $_REQUEST['players']; echo var_dump($players); $players = json_decode($players); echo 'players: ' .$players. '--'. $players[0] . '--'. $players[0]->id; Debugging in chrome, the JSON players var looks like this before it is sent: JSONplayers: "[{"id":"Percipient"},{"id":"4"}]" And when I vardump in PHP it looks OK, giving this: string(40) "[{\"id\":\"Percipient\"},{\"id\":\"4\"}]" But I can't access the PHP array, and the echo statement about starting with players: outputs this: players: ---- Nothing across the board...maybe it has something to do with the \'s in the array, I am new to this and might be missing something very simple. Any help would be greatly appreciated. note I've also tried json_decode($players, true) to get it as an assoc array but get similar results.

  • Drupal. Use AJAX to update view's content

    - by ozke
    Hi, I've created a view in Drupal that retrieves a list of nodes. The display of this view is a page and it works perfectly well. It does even allow me to filter its content by argument. See the current's view configuration (click to enlarge): I want to use AJAX to use the filter (by parameter) functionality without reloading the page. I've enabled the "Use AJAX" option but I am not sure on how to continue. Any ideas on how to do that? By the way, I'm building my own theme (in case that changes anything). Thanks in advance Update: Basically, this view works when I browse through section/parameter1, section/parameter2... but I want to do the same with AJAX, without reloading the page. I hope is clearer now

  • jquery load php file - result is not complete

    - by Mark Nolan
    I'm trying to load or better reload a DIV with content from an included php file. so the file is included in the webadmin.php from the location webadmin/pages.php. Then i alter some data in the DB through serializing. Now I would like to reload the pages.php from the callback of the serialize POST with load();. This all works fine up until the moment the data is supposed to be displayed in the div - i believe its because the php file is loaded from a different location, so the include paths for the DB Connection etc are probably wrong... Should I really write an extra PHP File for jquery or is there a way to tell jquery where to load it from? Its the first time I'm doing this - so bear with me for a moment on this one... Thanks! I guess it wont be much use, but heres the load code: $("#right").load("webadmin/pages.php");

  • Google Maps API v3... non-mobile?

    - by andrhamm
    I'm trying to make a Google Maps widget for my website but all of the examples are for full-screen mobile devices. The tutorials work when I copy paste them exactly as shown but they don't seem to work when I want them to only occupy a portion of the page. From what I've read, the v3 is the best API yet (for what I need) because of its speed and compatibility with mobile devices. I plan to make a widget very similar to the MarkerClusterer example from the demo gallery but I can't get it working. Is this a common issue? I know I'm being vague but I would appreciate some help. Thanks

  • Printing saved HTML to jsp keeps getting corrupted

    - by JWL
    I have a JAVA object where I save a HTML string value I call message. The saved data looks like the below, You have received a new <a href='' onclick='return popupRentalView('5282053859835904');'>Rental Request 5282053859835904</a>. Please view your open orders. But when printed to the JSP file and displayed at runtime using <%=pm.getMessage()%> or <%out.print(pm.getMessage());%> The actual html code comes out all messed up, You have received a new <a 5282053859835904');'="" onclick="return popupRentalView(" href="">Rental Request 5282053859835904</a> . Please view your open orders. Any thoughts on why the displayed string does not match the saved string? JAVA code for saving is note.setMessage("You have received a new <a href=\"\" onclick='return popupRentalView('" + requestId + "');'> Rental Request " + requestId + "</a>. Please view your open orders.");

  • Using JQuery to get text of a div that's a child of a header to replace a different header

    - by Stevie Jenowski
    Hello all, I'm trying to get the text contents of a .div('.child#') child of my event.target('h6.class'), and replace my other headers('h1.replacHeader#') using this script below... $('h6.class').click(function(event) { var $target = $(event.target); $('.replaceHeader1').replaceWith("<h1 class='replaceHeader1'>" + $target.children(".child1").text() + "</h1>"); $('.replaceHeader2').replaceWith("<h1 class='replaceHeader2'>" + $target.children(".child2").text() + "</h1>"); }); }); I've noticed that .text() apparently doesn't apply to an event.target... So how could I go about achieving this?

  • how to redraw markers without redrawing the map? google maps.

    - by vishwanath
    I currently have a implementation where some markers coming from JSON list is shown, on a particular area, Now I want to filter these marker depending upon some criteria, I have done the filtering part, and got the filtered list. Now to render this markers on the map again, The current implementation loads the js with a key again, also creates the GMap2 object and draws the list of marker on the newly created map, which is really annoying. I want map to be there and only markers to be added and removed from the map. Any help is appreciated
