• What to use to create bar, line and pie charts with javascript compatible with all major browsers?

  - by marcgg

  I used to work with flot but it doesn't support pie charts so I'm forced to change. I just saw JS Charts, but their documentation is very obscure regarding cross browser compatibility (I need it to be IE6+ compliant :). Also this will be for commercial use, so I'd rather have something that I can use free of charge jQuery Google chart looks really nice and is well integrated with rails (the framework I'm using) but I'm not sure how good it is. So what do you guys use? What would you recommend keeping in mind that: It will be for commercial use (I can deal with a license, but I'd rather avoid that) It needs to be javascript (no svg, no flash please) It needs to be compatible with IE6+, FF, Chrome, Opera and Safari It needs to be pretty ^^ If it uses jQuery it's even better

• PHP - Looking for an HTML Generator/Manager

  - by John Himmelman

  I'm trying to find a tool that I can use to generate markup programatically (non-irl word). Here is an example of what I'm trying to accomplish in pseudo-code... $htmlDoc = new HTML_Document(); $htmlDoc->setTitle('Cool Title'); $htmlDoc->addJs('some_js_file.js'); $htmlDoc->addStylesheet('some_css_file.css'); $divElement = new HTML_Element_Div(); $htmlDoc->append('body', $divElement); $output = $htmlDoc->generate(); What is the best tool for this?

• Eclipse Basic Web Development?

  - by Sean Ochoa

  I want to start doing web development with Eclipse. Not Java, tomcat, axis2, or anything else anymore complicated than basic XHTML / JS / CSS development, at this time. Problem 1: I realize that it can edit those files, but its trying to manage my HTML docs as part of "my workspace", and all I want it to do is manage the files as part of my local www server HTdocs directory. Problem 2: I would like to edit WYSIWYG-style, if possible. I tried installing a plug-in for that, but I wasn't able to get w4 toolkit to function properly. This would really help me to speed up development, I think. Follow-up: I've installed WTP and its dependencies (except for the tests portion, which had install problems due to dependencies that were seemingly irreconcilable).

• Add client-side events to ASP.Net custom control at runtime

  - by nw

  I'm building an ASP.net custom control that implements IScriptControl. I would like other users of my control to be able to assign client-side event handlers to the control. Unfortunately the JS generated by IScriptControl is always injected at the very bottom of the rendered page (see below), so any attempt to assign an event handler in the ASPX page fails because the code executes too early. ... <script type="text/javascript"> //<![CDATA[ Sys.Application.initialize(); Sys.Application.add_init(function() { $create(MyNamespace.MyControl, {}, null, null, $get("my_control_id")); }); //]]> </script> </form> What's the right way to assign an event handler to the instantiated control upon page load?

• Uploadify uploadSettings with scripData does not work

  - by kubilayeksioglu

  Hi everyone, I am sending a file to my Java Servlet via jQuery Uploadify, there are no problems while sending the actual file. But when I try to send some scriptData with file along, to process on Servlet it just does not send anything. Here is the JS code: $("button").click(function(){ $("#uploadify").uploadifySettings('scriptData', {'length':'0.2'}); $('#uploadify').uploadifyUpload(); }); $('#uploadify').uploadify({ 'uploader': 'assets/uploadify/uploadify.swf', 'script': 'upload', 'folder': '/uploads' }); And here is the Servlet code on the server side: out.println(res.getParameter("length")); Only output I get is null, while expecting "0.2". I just cannot get what's wrong and any kind of help will be appreciated. Thanks in advance.

• Web Application Translation, methods and tools

  - by CiscoIPPhone

  I've developed a web application. It needs to be translated to languages other than English in the future, and ideally the translators shouldn't need to know HTML/JS/C++ to provide the translation. The server side of the web application is written in C++ and the majority of the localised text is in the HTML files. My question is: What approaches are there to translating web applications? - Are there any existing tools that would enable a translator who doesn't understand HTML to translate a site? Should I write an application that extracts the localised text from a html file and can re-substitute translated text? Do you just provide the html file to your translators to be localised? I'm aware the question isn't strictly programming related but the solution may involve programming and it may require some software engineering.

• Turn a collection of headings, paragraphs and lists into one hyperlink

  - by Moak

  Is there a valid non js way to turn a collection of headings, paragraphs and lists into one url? (like in advertisements?) <a href="http://www.example.com" class="allclickable"> <h2>Fresh Bread</h2> <p>Delivered to your door</p> <ul> <li>Daily</li> <li>Fresh</li> <li>Bread</li> </ul> </a> This does not validate and I do want the href to be display as block element (so also the space around the text is clickable). Cheers

• URL Rewrite in htaccess problem

  - by davykiash

  Am rather new to this world of htaccess redirects.Am trying to force all redirects in my Zend MVC to my https but I get a requested URL not found error on requests that dont go though the index controller Example https://www.example.com/auth/register gives a requested URL /auth/register not found error. However if I remove the https redirect rule it works fine over http. If I adjust the URL to https://www.example.com/index.php/auth/register it works fine. The URL https://www.example.com/index/faq works just fine since it goes through the index controller. My .htaccess file looks like this RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L] RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L] <ifModule mod_gzip.c> mod_gzip_on Yes mod_gzip_dechunk Yes mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$ mod_gzip_item_include handler ^cgi-script$ mod_gzip_item_include mime ^text/.* mod_gzip_item_include mime ^application/x-javascript.* mod_gzip_item_exclude mime ^image/.* mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.* </ifModule> What do I need to adjust to get the URL https://www.example.com/auth/register working?

• Phonegap - iOS keyboard is not hiding on outside tap of input field

  - by Prasoon

  On input text focus, keyboard appears as expected. But when I click outside of the input text, keyboard does not hide. I am using java script and jQuery. With jQueryMobile JS and CSS - page behaves correctly. But for this project we are not using jQueryMobile. This problem is only with iOS simulator/device. With Android, it's working perfectly fine. I even tried using document.activeElement.blur(); on outer element click/tap. But then I am unable to focus to input text, because that input text is inside that outer element.

• Geolocation under firefox 3.6 requires Proxy Authentication?

  - by prem

  I am trying to share my location on geolocation enabled pages from firefox 3.6, but doesn't seem to get any kind of success or failures. When I wrote my custom js containing navigator.geolocation.getCurrentPosition(func1,func2), the success callback isn't called at all. When I tamper the http requests on firefox, the request to https://www.google.com/loc/json returns with status: 407 [Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )]... Yes, my network is behind a proxy server. But the same works with Chrome. I didn't try other browsers yet.

• focus on page scroll navigation when using iPad

  - by user1154435

  I've used Page Scroller Lite http://pagescroller.com to set up a single-page site at http://www.thestitchshop.co.uk There seems to be an issue that scolling works only once when clicking on a menu item. It will only work again after one touched scrolls the page 'manually' by sliding the finger across the page. Apparently, the issue is that the content gets the focus after the scroll and tapping on navigation then actually taps behind it. I've tried contacting the author of pagecroller, but no luck. So, how do I fix it? I don't have any JS knowledge, so I need a little more help along the way. Many thanks. By the way,I've posted the same question here http://www.sitepoint.com/forums/showthread.php?886838-Problem-with-page-scrolling-on-iPad and I've tried adding the suggested code somehow, but without success.

• Lightweight web browser for testing

  - by Ghostrider

  I have e very specific test setup in mind. I would like to start a web-browser that understands Javascript and can use HTTP proxy, point it to a URL (ideally by specifying it in the command line along with the proxy config), wait for the page to load while listening (in the proxy) requests are generated as web-page is rendered and Javascript is executed, then kill the whole thing and restart. I don't care about how the page renders graphically at all. Which browser or tool should I use for this? Ideally it should be something self-contained that doesn't require installation (just an EXE file that runs from command line). Lynx would have been ideal but for the fact that it doesn't support JS. It should have as small memory footprint as possible.

• Overriding disabled input and textarea with CSS

  - by igluratds

  Hi, Im trying to override the grey text of a disabled input and textarea. At the moment Im only really concerned with it working in Webkit and Mozilla. At the moment Im currently using every trick in the book that I know of: input[@disabled=true], input[@disabled], button[disabled]:active, button[disabled], input[type="reset"][disabled]:active, input[type="reset"][disabled], input[type="button"][disabled]:active, input[type="button"][disabled], select[disabled] > input[type="button"], select[disabled] > input[type="button"]:active, input[type="submit"][disabled]:active, input[type="submit"][disabled],input[disabled="disabled"], input[disabled] { color: black !important; } Sure it does change the colour if I change it to something else, however when I choose black it is still greyed out a bit. Any ideas? I am using Ext JS if I can use that to manipulate it. Thanks.

• How to debug CSS/Javascript hover issues

  - by Jason Creighton

  I often find myself wanting to debug CSS layout issues that involve DOM changes caused by Javascript in reaction to a hover event or different CSS rules applying due to the :hover selector. Normally, I'd use Firebug to inspect the element that's giving me trouble and see what its CSS properties were, and where those properties come from. However, when hovering is involved, it becomes impossible, because as soon as you move your mouse down to the Firebug panel, the elements you're interested in are no longer hovered, the CSS rules that apply are different, and (in the case of JS hovers) the DOM is changed. Is there any way I can "freeze" the state of the DOM and application of :hover in order to inspect the DOM as it was during a hover event? Any other ideas on how to debug this sort of issue are welcome, of course.

• Need help in changing the background color of "flair"

  - by Bragaadeesh

  Hi, I am trying to include the "flair" in my website. One problem I face is that I cannot change the background color. I went to the flair page and saw that I should use the css style to change. I am very poor in CSS. I have my domain in blogger. So it would be really helpful if someone could tell me how to do it. This is what i've done which is not working <script style="background-color:grey" src="http://stackoverflow.com/users/flair/252398.js?theme=clean" type="text/javascript"></script>

• Build Systems for PHP Web Apps

  - by macinjosh

  I want to start automating more of my web development process so I'm looking for a build system. I write mostly PHP apps on Mac OS X and deploy Linux servers over FTP. A lot of my clients have basic hosting providers so shell access to their servers is typically not available, however remote MySQL access is usually present. Here is what I want to do with a build system: When Building: Lint JavaScript Files Validate CSS Files Validate HTML Files Minify and concatenate JS and CSS files Verify PHP Syntax Set Debug/Production flags When Deploying Checkout latest version from SVN Run build process Upload files to server via FTP Run SQL scripts on remote DB I realize this is a lot of work to automate but I think it would be worth it. So what is the best way to start down this path? Is there a system that can handle builds and deploys, or should I search for separate solutions? What systems would you recommend?

• Servlet receives OPTIONS instead of GET requests from jQuery?

  - by Urs

  All I want to achieve is to implement a servlet providing a json feed for my fullcalendar application. When I inspect http://arshaw.com/js/fullcalendar/examples/json.html with Bugzilla, I see that GET-requests are sent to receive the json feed. However, when I use this example within my scenario, fullcalendar seems to send OPTIONS-requests. The only difference is that I replaced "events: "json-events.php" with "http://localhost:8080/CalendarServletTest/HelloWorldServlet" (the url of my servlet). What do I miss? Or is this really a bug?

• debugging with internet explorer

  - by baiano

  I have some code that I thought I had written so that it would play nice on IE. But apparently it does not. I use IE8 for my testing and get quite frustrated with the built-in debugging 'tool'. I found that firebug has a javascript tool that debugs for IE but I have to click it for every page, wait for it to load and then test my script. Is there a way to make IE ALWAYS load the firebug .js file? I tried searching for way to set up a custom header file for my IE installation but was unsuccessful. Is there another tool out there that would be better/easier to use? Another way to test scripts for IE compatibility?

• prevent _doPostBack getting rendered in button markup

  - by Christo Fur

  Hi Is it possible to prevent the _doPostBack() call getting rendered on a button? I would like add some custom logic prior to calling the postback. I have added an onClick event to the button e.g. <button id="manualSubmit" runat="server" class="manual-submit" onclick="$('#jeweller-form').hide();" /> However, this just gets rendered inline before the _doPostBack() But the postback gets fired before the jQueryHide takes place I would like to call my own JS function then manually trigger the postback any ideas?

• Making an SVG DOM JavaScript class

  - by CryptoQuick

  I'm unsatisfied with other JavaScript libraries and frameworks like jQuery, MooTools, and Raphael, because of their inability to support SVG grouping. You'd think it'd be a very simple thing for them to implement. Anyway, I'm trying to make a JavaScript class (using John Resig's class.js script) like this: var El = Class.extend({ el: null, svgNS: "http://www.w3.org/2000/svg", init: function (type) { this.el = document.createElementNS(this.svgNS, type); }, set: function (name, attr) { this.el.setAttributeNS(null, name, attr); }, get: function (el, name) { var attr = this.el.getAttributeNS(null, name); return attr; }, add: function (targEl) { targEl.el.appendChild(this.el); }, remove: function (targEl) { targEl.el.removeChild(this.el); }, setEl: function (docId) { this.el = document.getElementById(docId); } }); I can add elements to the DOM using these statements outside of the class, but storing the element inside the class becomes problematic. Anyone have any creative ideas?

• deny iframe javascript to scroll parent window

  - by gucki

  I've a site with banner ads, loaded using iframes. The banner ads always scroll the parent window when the banner doesn't complety fit into the visible region. This is really annoying and I'd like to deny the javascript of the iframes to scroll the main window. Here is what I already tried: Move the iframe src code to another domain. Normally js from another domain should not be allowed to access the parent window, is it?! This doesn't work. Overwrite window.moveTo, window.scrollTo, window.scrollBy in parent with my own functions. This doesn't seem to work neither, as none of these functions seems to be called. :-( Any help would be really great :-)

• Javascript clears a variable after there is no further reference it

  - by Praveen Prasad

  It is said, javascript clears a variable from memory after its being referenced last. just for the sake of this question i created a JS file with only one variable; //file start //variable defined var a=["Hello"] //refenence to that variable alert(a[0]); // //file end no further reference to that variable, so i expect javascript to clear varaible 'a' Now i just ran this page and then opened firebug and ran this code alert(a[0]); Now this alerts the value of variable, If the statement "Javascript clears a variable after there is no further reference it" is true how come alert() shows its value. Is it because all variable defined in global context become properties of window object, and since even after the execution file window objects exist so does it properties.

• caching static files for ruby on rails application using nginx

  - by splintercell

  I have been trying for some time to serve & cache static files for my rails app using nginx. the rails app server runs mongrel_cluster and is deployed on a different host than that of nginx. following many of the available discussions I tried the following server { listen 80; server_name www.myappserver.com; ssl on; root /var/apps/myapp/current/public; location ~ ^/(images|javascripts|stylesheets)/ { root /var/apps/myapp/current; expires 10y; } location / { proxy_pass http://myapp_upstream; } } But nginx fails to find the images and to load the css and js files. Can anyone help me out here? My aim is to configure nginx in such a way that it caches the static files till expiry. Please suggest me some way to achieve this or am I missing any point here?
