  • 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.

  • Dynamically loading JavaScript synchronously

    - by spoon16
    I'm using the module pattern, one of the things I want to do is dynamically include an external JavaScript file, execute the file, and then use the functions/variables in the file in the return { } of my module. I can't figure out how to do this easily. Are there any standard ways of performing a pseudo synchronous external script load? function myModule() { var tag = document.createElement("script"); tag.type = "text/javascript"; tag.src = "http://some/script.js"; document.getElementsByTagName('head')[0].appendChild(tag); //something should go here to ensure file is loaded before return is executed return { external: externalVariable } }

  • What is the easiest way to send a Javascript array via JSON to PHP?

    - by dscher
    I have a few arrays that I want to send to process with PHP. Using json2.js I will stringify the arrays like so: var JSONlinks = JSON.stringify(link_array); var JSONnotes = JSON.stringify(note_array); but then I'm confused. Do I need to use a XMLHttpRequest object? Is there another way? If that is the simplest way, could someone please just share the most basic instance of the code needed in order to send to PHP where I can then use JSON decode? I think it might help others in the future really. I'm currently using Jquery and I know there are many options out there for frameworks and each one may or may not make this process any easier. If you're using a framework in your reply please mention why you'd choose that framework rather than just javascript.

  • 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]

  • Codebase for making a Flash-based interactive map with SVG vector data?

    - by Mike
    I'm looking for a way to take SVG path info (basically a string of coordinates) and dynamically draw it with Actionscript. Icing on the cake would be if those shapes could detect mouse events to trigger JS and dynamically change their appearance (fill, stroke, etc...). I'm currently trying something similar to this (http://raphaeljs.com/australia.html) using SVG but it's just too slow in IE. I've also tried Google's SVG Web (http://code.google.com/p/svgweb/) which basically does exactly what I'm looking for (it converts SVG to Flash in IE) but again, it's sloooooow - which is why I'm considering doing the whole shebang in Flash. Anyone know of some links to point me in the right direction?

  • How can I "slide up" a view on android from the bottom of a screen?

    - by Jakub Arnold
    I'm trying to make a really simple slide up list view, which is displayed when a user clicks on a button at the bottom of the screen. Here's how it should look: And a complete implementation in HTML/JS http://jsbin.com/utAQOVA/1/edit I've tried to use RelativeLayout to position the list just below the button, and put that whole thing into a wrapper and then animate that up/down (same as in the JSBin above). The problem is that the bottom part which isn't visible in the beginning is somehow clipped, even if I slide it up. Evern if I initially show a portion of the list as the screenshow below shows, the bottom part gets clipped when it moves up and only the part that was initially visible is displayed. What would be a proper approach to do this kind of animation? Here's a relevant portion of the layout

  • Taking web page screen shot in Windows 8 Metro app

    - by Megan
    I'm trying to take screen shot of web page in Windows 8 Metro app. So far the only helpful control is the WebView. Unfortunately it does not contain any method like DrawToBitmap (known from Forms WebBrowser control). Am I missing something? Different approach would focus on injecting some JS (e.g. html2canvas) to page rendered in WebView but I don't think it is possible due to security reasons. I would greatly appreciate any help.

  • 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

  • android browser downloadfile.bin (wordpress cf7)

    - by roman
    i got a little problem with a wordpress site that uses contact form 7 and android browser (at least android v1.5). when a user submits the cf7 form (using ajax followed by a js redirect) and tries to return to the forms page later (using the back button as well as opening the form's url) the download prompt for a 'downloadfile.bin' appears. this behavior can not be reproduced on any other mobile or desktop browsers. could anyone shed some light on this issue? thank you in advance!

  • Bind jQuery UI autocomplete using .live()

    - by seth.vargo
    I've searched everywhere, but I can't seem to find any help... I have some textboxes that are created dynamically via JS, so I need to bind all of their classes to an autocomplete. As a result, I need to use the new .live() option. As an example, to bind all items with a class of .foo now and future created: $('.foo').live('click', function(){ alert('clicked'); }); It takes (and behaves) the same as .bind(). However, I want to bind an autocomplete... This doesn't work: $('.foo').live('autocomplete', function(event, ui){ source: 'url.php' // (surpressed other arguments) }); How can I use .live() to bind autocomplete? UPDATE Figured it out with Framer: $(function(){ $('.search').live('keyup.autocomplete', function(){ $(this).autocomplete({ source : 'url.php' }); }); });

  • Resetting a partial using RJS, and passing an instance variable?

    - by Elliot
    Hey guys here is my code (roughly): books.html.erb <% @books.each do |book| %> <% @bookid = book.id %> <div id="enter_stuff"> <%= render "input", :bookid => @bookid %> </div> <%end%> _input.html.erb <% @book = Book.find_by_id(@bookid) %> <strong>your book is: <%=h @book.name %></strong> create.rjs page.replace_html :enter_stuff, :partial => 'input2', :object => @bookid Only create.js doesn't seem to work though, if instead of passing the partial I passed "..." it does work, so I know its that there are instance variables in the partial that aren't being reset. Any ideas?

  • Changing background images like this

    - by Azzyh
    If you guys check out this webpage: http://www2.scandvision.se/oresund10/ How have they done this background fade in fade out? When i check the source this <img id="wrapper-background" src="images/body-background-0.jpg" alt="Background" /> and i think theres some kind of script maybe php or js, or both, that every 5 sec changes the background: images/body-background-1.jpg images/body-background-2.jpg images/body-background-3.jpg and so on.. So how did they do this? an example would be great, as i want to learn how to do that. If i was going to do something like this i think i would only manage to do a script in php that randomize everytime you refresh. Thank you, this will expand my knowledge

  • How do you determine up/down latency of a web app.

    - by Brodie
    I am trying to work out how to calculate the latency of requests through a web-app (Javascript) to a .net webservice. Currently I am essentially trying to sync both client and server time, which when hitting the webservice I can look at the offset (which would accurately show the 'up' latency. The problem is - when you sync the time's, you have to factor in latency for that also. So currently I am timeing the sync request (round trip) and dividing by 2, in an attempt to get the 'up' latency...and then modify the sync accordingly. This works on the assumption that latency is symmetrical, which it isn't. Does anyone know a procedure that would be able to determine specifically the up/down latency of a JS http request to a .net service? If it needs to involve multiple handshakes thats fine, what ever is as accurate as possible. Thanks!!

  • How does browser work with expiration headers, cache-control headers, last-modified-header ?

    - by Umair
    I am a web developer, have worked with PHP and .NET both. having over a year of experience working on web I haven't been able to understand the browser caching features thoroughly, I hope Web Gurus here can help me with it. Questions I have in my mind are : How does browser actually caches stuff, does it request for to see if the cached file has changed on the server or not, What is the Ideal way for a developer to make use of browser chaching to its full, but also to be able to push new changes on the site with no hassle at all. I think if browser somehow chaches my CSS and JS and Images, and then just makes a checks for their modification to the server everytime, this can sort the issue. but I am not sure how to do it, waiting for interesting answers :)

  • jQuery: Sorting hierarchical data?

    - by Industrial
    Hi everybody, I have tried for some time to work out a way of sorting nested categories with jQuery. I failed to build my own plugin to do this, so I tried to find something that were available already. Tried a few hours now with this one, http://www.jordivila.net/code/js/jquery/ui-widgetTreeList_inheritance/widgetTreeListSample.aspx and cant get it to work. What are the alternatives of creating a jQuery / jQuery UI script that handles sorting children and parent categories in a way that can be combined with a AJAX PHP backend to handle the actual sorting in the database? Thanks!

  • Removing DOM event handlers in long-running browser session

    - by Chris Beck
    I have a browser interface with a ul#contacts list on the left and div#contact property panel (email, phone) on the right. Click a contact in the list and my app makes an XHR request to get the contact property HTML fragment and update div#contact.innerHTML. Each contact fragment has an "Edit Contact" link. With JS, I progressively upgrade that link with an event listener that performs an XHR request to replace the static property panel with an in-place edit form. This can happen many times during a single browser session. How should I clean up my "Edit Contact" event listener? Do I need to remove it manually before the form overwrites the property panel? Or is the event listener cleaned up automatically when the contents of div#contact (and the node that I'm listening on) is overwritten? FWIW, I still consider IE6 to be part of my target market.

  • Can a Javascript bookmarklet overlay an image on a web page?

    - by songdogtech
    Can a bookmarklet be used to overlay an image on a web page? Not as a pop-up, but as a image positioned by CSS and with a high z-index to display on top of other elements. And without a mask i.e., Shadowbox or similar jQuery effect. Just an image from a URL and positioned in the bottom left hand corner of the browser window. This is what I have so far, but it may be the wrong direction to be going: javascript:(function(){document.write("body {background-image:url(http://mydomain.com/image.png); position: absolute; left:50px; top:300px; z-index:9999;}");})() I have a JS function that works as a bookmarklet to change the case of text on the page, and now I'd like to be able to show an image when the bookmarklet is used.

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.

  • 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?
