  • Pass javascript array to php by using curly braces key name

    - by user7031
    My js code: $(function(){ var arr = new Array('jj', 'kk', 'oo'); $.post('test12.php', {'arr[]': arr}, function(data){ alert(data); }); }); PHP code: <?php echo print_r($_POST['arr']); The thing is,$.post receive a key named 'arr[]',it should be used in PHP as 'arr[]' instead of 'arr',but '$_POST['arr[]']' doesn't work,'arr' works.Which seems that Jquery might do something with curly braces '[]' before sending something to PHP. Secondly,when I remove the single quotas around 'arr[]',PHP can not receive anything by using $_POST['arr'];,I don't know why? Doing this task in a traditional way with no curly braces: $.post('test12.php', {arr: arr}, function(data){ alert(data); }); It works fine. So when sending javascript array to PHP,why bothering using single quote and curly braces like 'arr[]' instead of using a concise way like arr:arr My return result is Array( [0]=>jj [1]=>kk [2]=>oo ) 1 Notice there is a 1 under the array,why?

  • How do you override an existing html form to use jquery to post the form?

    - by Chris
    I have a simple form that I am currently posting back to the server to update a nickname. What jquery code do I add (without changing the form) so that the page will not refresh, but instead jquery will post the form in the background and then pop up an alert message containing the reply back from the server? <form method="post" action="http://www.myserver.com/update_nickname" name="input"> Quick form to test update_nickname:<br> New nickname:<input type="text" value="BigJoe" name="newNickname"><br> <input type="submit" value="Submit"> </form> <script src="jquery-1.4.2.min.js" type="text/javascript"> </script>

  • KeyboardState.pressed is always true after .prompt or alert - Why?

    - by Yenza
    As the title says, I have tried THREEx and Stemkovskis standalone KeyboardState.js , and neither of them seems to update properly. This is my code: m_vKeyboard = new THREEx.KeyboardState(); // m_vKeyboard.update(); // if using stemkovskis if (m_vKeyboard.pressed("F")) { alert("And now it is always true!"); } you click the F key once, release it; alert window pops up, click OK, it pops up again for all eternity. How come?

  • DOM class injection in PHP

    - by Adam Kiss
    idea Via jQuery, I was able to mark all :first-child and :last-child elements in document (well, almost all :)) with class first which could I later style (i.e. first li in ul#navigation would be easily adressable as ul#navigation .first). I used following code: var $f = $('*:first-child') $f.addClass('first'); var $l = $('body *:last-child') $l.addClass('last'); question Now, my question is if it's possible to do the same via php, so non-JS users/gadgets could have the same effects and additional styling and also it would be less overkill on browser. So, is it possible to capture output, parse it as html and inject this class easily in php?

  • Design interoperable web services

    - by Zyd
    Hi everyone, I'm designing a set of web services to allow our clients to connect from their apps to one of our systems. Our clients have their apps developed in all varieties of frameworks (.NET, Java, PHP, Python and even the occasional all JS app), so obviously WS is the way to go. Investigating a little about truly interop WS I've found that the way to go is to design first the WSDL and XSD and derive the implementations from there. What i'm really looking for is guidance if this is really the way to go. I've read that WCF creates interoperable WS but i'm not a fan of MS creating something standard. Should i use WCF or there is a good set of tools for designing WSDL and XSD without the pain i'm expecting. Thanks in advance

  • Halting Django's dev server via page request?

    - by Ben Blank
    I'm looking at writing a portable, light-weight Python app. As the "GUI toolkit" I'm most familiar with — by a wide margin! — is HTML/CSS/JS, I thought to use Django as a framework for the project, using its built-in "development server" (manage.py runserver). I've been banging on a proof-of-concept for a couple hours and the only real problem I've encountered so far is shutting down the server once the user has finished using the app. Ideally, I'd like there to be a link on the app's pages which shuts down the server and closes the page, but nothing I see in the Django docs suggests this is possible. Can this be done? For that matter, is this a reasonable approach for writing a small, portable GUI tool?

  • Javascript src starts with //?

    - by Chris
    I'm starting to see more and more script references show up like so: <script type="text/javascript" src="//somedomain.com/somescript.js"></script> Note the lack of http: at the beginning of the src attribute. It seems to work fine and avoids the messy requirement of detecting http vs https, but I've never actually seen this uri format referenced anywhere. Where did it come from? Is this behavior documented anywhere? Is it guaranteed to work in any browser?

  • Using JQuery replaceWith with a JavaScript Variable

    - by JJ56
    Here's my html: <div class="timer">Not Started</div> And JS/JQ: var seconds = 10; var minutes = 0; setTimeout("updateTimer()", 1000); function updateTimer() { if (seconds == 0 && minutes != 0) { minutes -= minutes; seconds = 59; alert (seconds); } else if (seconds == 1 && minutes == 0) { alert ('done'); } else { seconds = seconds - 1; //alert (seconds); $(".timer").replaceWith(seconds); } setTimeout("updateTimer()", 1000); } Instead of replacing Not Started with 10, 9, 8..., Not Started disappears.

  • jQuery Dialog open hides background content in IE7

    - by JoshReedSchramm
    Hey all, I'm working on an application where the page layout is essentially a bunch of absolutely positioned containers. There is a header, sidebar and content area. The content area has its own header and footer which are fixed on the screen. The main part of the content area scrolls but nothing else does. So, we are using jQuery dialog for popup boxes and in IE7 with this new layout when i open a dialog the rest of my content in the background vanishes. I'm left with the page header and the footer of the content area and that's it. In Firefox and believe it or not IE6 it works fine. We are using ie7.js in ie6 though to make things not suck. Anyone have any clue why opening a dialog in jquery would screw up absolute positioning and make stuff vanish?

  • Zend Framework on a Shared Host

    - by manyxcxi
    I am trying to push my first ZF project to my shared hosting provider. I have done a lot of testing on my home server and everything is working great. My issue is that I do not know how to set up my .htaccess files on the shared hosting provider to make it work correctly. The ZF documentation says to configure my Apache config VirtualServer DocumentRoot to /whatever/path/project-folder/public, but I don't have that kind of access. How do I get around this? I have seen http://stackoverflow.com/questions/1115547/zend-framework-on-shared-hosting but none of those solutions have worked for me. My application path looks like this / - .htaccess - /application ... - /public -- .htaccess -- index.php -- ... ... My .htaccess files look like: /.htaccess RewriteEngine On RewriteRule !\.(js|gif|jpg|png|css|txt)$ public/index.php [L] RewriteCond %{REQUEST_URI} !^/public/ RewriteRule ^(.*)$ public/$1 [L] /public/.htaccess RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L]

  • Sinatra, JavaScript Cross-Domain Requests JSON

    - by pex
    I run a REST-API build on top of Sinatra. Now I want to write a jQuery Script that fetches data from the API. Sinatra is told to response with JSON before do content_type :json end A simple Route looks like get '/posts' do Post.find.to_json end My jQuery script is a simple ajax-call $.ajax({ type: 'get', url: 'http://api.com/posts', dataType: 'json', success: function(data) { // do something } }) Actually everything works fine as long as both runs on the same IP, API and requesting JS. I already tried to play around with JSONP for Rack without any positive results, though. Probably I just need a hint how to proceed.

  • Why is iphone Simulator not rendering HTML5 page correctly?

    - by user364978
    hello all, I have a page I am developing in .net using HTML5 intended for a WebView in an iphone App. The page looks just fine in Safari. When I load it in the iphone Simulator it is rendering as plain text, no styles or js loading. I thought it might be an issue with .net, but seeing as it works in Safari i am stumped. When I use the XHTML doctype it works just fine in the Simulator. Any ideas why this is occurring and what the fix may be? Thanks!

  • Closing the iframe which was opened for "ajax uploading"

    - by KPL
    Hello people, http://www.atwebresults.com/php_ajax_image_upload/ I am using this script for so-called AJAX file upload but which is actually based on opening of iframe and then submitting form from it. What my problem is, I am using this script in a form which will have some other fields too. So after uploading the image, when I click submit at the end of the form, the form is submitted to the file which was opened in iFrame. As I am not an expert in JS, can you guys help me with this? I tried changing the action attribute and tried to completely remove the form too, but nothing helped.

  • Javascript form validation events

    - by user307922
    Hi All, I am making a small form for a php app and had a question regarding javascript validation. What is the best event to run the javascript validation on the input value? Is it the "focusout" event? I used "focusout" to originally but it creates problems when the user hits enter while they are still focused on any particular field in the form. Should I run the js validation when the user clicks submit? Just looking for some advice. Thanks! Chuck

  • How do I parse this invalid JSON string in jQuery?

    - by LesterDove
    Hi, I am looking to access the various bits of data in this data attribute: <div class="location" data="{id: 4, point: {lng: -71.413364, lat: 41.673681}, category: 'Restaurant'}"> The data attribute is easy enough to reach in jQuery, of course. But the string seems to be a non-standard or invalid form of JSON. I've tried JSON.parse() and also a basic JS method of splitting the array. By all accounts, it just seems to be an invalidly-serialized string. Will I need to reformat the data string? (it doesn't come from me, and it's used by other routines that I'd rather not break, so...)

  • JavaScript helper libraries? No DOM or AJAX stuff

    - by Melmacian
    As I'm writing JavaScript I'm always missing some fairly basic language features that JavaScript just don't have. So is there any library that would bring such features as trim, sprintf, str.endwith and etc. functions to JavaScript ? I just have written those functions too many times and I'm also tired of copy/pasting them from my old code. It would be nice to have some library which has those implemented and tested in one place. Note that I'm not talking about Ajax/DOM-libraries like jQuery or Dojo and such. I know that those libraries bring some of the features that I'm talking here, but not all. And I would like to have also an environment independent library so that same library could be used with server side JavaScript . Best library so far that I've found is php.js, but I don't like how it is polluting the global namespace. I'm also not too fond of how PHP-functions are named.

  • FreshBooks API Libraries

    - by Hristo
    Hello, I am posting this question as I couldn't find the answer (which is probably very easy, but apparently not for me) anywhere.. I am new to FreshBooks (no only the API) and I want to use it for some automatically generated invoices. I was trying to run some of the source code examples (the PHP and JS libraries in particular): http://developers.freshbooks.com/api/samplecode/ The problem is that I get an error message: "Connection error" Do I need to set up anything else in the example files besides my API and token obtained from the FreshBooks site? P.S.: I am running the examples from a local server but I don't believe that's the problem. Thank you very much in advance!

  • Performance problems when loading local JSON via <script> elements in IE8

    - by Jens Bannmann
    I have a web page with some JS scripts that needs to work locally, e.g. from hard disk or a CD-ROM. The scripts load JSON data from files by inserting <script> tags. This worked fine in IE6, but now in IE8 it takes an enormous amount of time: it went from "instantly" to 3-10 seconds. The main data file is 45KB large. How can I solve this? I would switch from <script> tags to another method of loading JSON (ideally involving the new native JSON parser), but it seems locally loaded content cannot access the XMLHttpRequest object. Any ideas?

  • Fetching content from Website on another Server

    - by benny
    Hi everyone. What i basically want to do is to get content from a website and load it into a div of another website. This should be no problem so far. The problem is, that the content that should be fetched is located on a different server and i have no source access to it. I'd prefer a solution using JavaScript of jQuery. Can i use a .htacces redirect to fetch the content from a remote server with client-side (js) techniques? I will also go with other solutions though. Thanks a lot in advance!

  • Set form action dynamically in https-area

    - by Beerweasle
    Hi, heres the problem explanation: Im on the domain https://www.example.com - theres an Order-Form with the Action https://www.example-otherdomain.com with an other SSL Certificate. On some conditions i set the form action to https://www.example.com so that it will be posted on our domain, but if the user uses a CreditCart it should get posted to https://www.example-otherdomain.com. So far so good. But in some rare conditions, users with CreditCards still posts their form to https://www.example.com. So my idea is: Is there some Same-Domain-Policy for Javascript/HTTPS to protect the user from phishing? It seems that to set the FormAction to the same domain works, but not to reset it to the external one (with JS). I cant reproduce this error, so im asking here if someone knows if theres such a problem. It doesnt matter which UserAgent the user has (there are post datas from FF, Chrome, Webkit, IE7/8) Thx!
