• How to launch standard browser out of Java application?

  Hi there how to I open a URL with the systems standard browser with Java? I currently use this code for opening a specific URL (locally stored html file), which works fine when I run the application with my IDE (Eclipse), but after bundling the software, it doesn't work any more. url = MainWindow.class.getResource("mySite.html"); helpMenuItem.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { try { java.awt.Desktop.getDesktop().browse(url.toURI()); } catch (URISyntaxException e1) { e1.printStackTrace(); } catch (IOException e1) { e1.printStackTrace(); } } }); Any suggestsions?

• twitter bootstrap typeahead ajax example

  - by emeraldjava

  I'm trying to find a working example of the twitter bootstrap typeahead element that will make an ajax call to populate it's dropdown. I have an existing working jquery autocomplete example which defines the ajax url to and how to process the reply <script type="text/javascript"> //<![CDATA[ $(document).ready(function() { var options = { minChars:3, max:20 }; $("#runnerquery").autocomplete('./index/runnerfilter/format/html',options).result( function(event, data, formatted) { window.location = "./runner/index/id/"+data[1]; } ); .. What do i need change to convert this to the typeahead example? <script type="text/javascript"> //<![CDATA[ $(document).ready(function() { var options = { source:'/index/runnerfilter/format/html', items:5 }; $("#runnerquery").typeahead(options).result( function(event, data, formatted) { window.location = "./runner/index/id/"+data[1]; } ); ..

• How to launch a file protocol URL with an anchor from Java?

  - by Jeff C

  From a Java program, I need to launch the default browser on a local HTML file, pointed to an anchor inside the file. In Java SE 6, the java.awt.Desktop.browse method will open the file, but will not honor the anchor, so something like the following opens the file at the top, but does not page the browser to the anchor: Desktop.getDesktop("file:///C:/foo/bar.html#anchor"); Sun says here http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6477862 that anchors are not supported in the file URI protocol. Does anyone have a better answer? I can use Java SE 6. I would be OK with a Windows only solution.

• multiline perl search and replace (one-liner)

  - by yaya3

  I want to perform the following vim substitution as a one-liner in the terminal with perl. I would prefer to allow for any occurences of white space and/or new lines, rather than explicitly catering for them as I am below. %s/blockDontForget">\n*\s*<p><span><a\(.*\)<\/span>/blockDontForget"><p><a\1/g I've tried this: perl -pi -e 's/blockDontForget"><p><span><a(.*)<\/span>/blockDontForget"><p><a$1/msg' I presume I am misinterpreting the flags. Where am I going wrong? Thanks. EDIT: The above example is to strip the spans out of the following html: <div class="block blockDontForget"> <p><span><a href="../../../foo/bar/x/x.html">Lorem Ipsum</a></span></p> </div>

• Best blogging tool to integrate into an existing website

  - by Brian515

  Hi all, I'm looking for an easy way to integrate a blog into a website that I've developed with HTML and CSS and have already put a considerable amount of time and effort into. I've looked at WordPress, Movable Type, b2evolution, and a few others, but they all seem like overkill for me. I'm only going to be posting 1 maybe 2 times a week at most. Plus, all of the aforementioned tools seem hard to customize. I want my blog to look like the rest of my website, but I don't want to rebuild my site based on one of the blogging tools. Because, as I said before, I've already spent a lot of time rebuilding the site using HTML and CSS. Any suggestions would be greatly appreciated. Thanks in advance!

• Urlredirect in MVC2

  In global.asax routes.MapRoute( "Test_Default", // Route name "test/{controller}/{action}", // URL with parameters new { } ); routes.MapRoute( "Default", "{universe}", new { controller = "notfound", action = "error"} ); I have a controller: Home, containing an action: Index Enter the url in browser: h**p://localhost:53235/test/home/index Inside the index.aspx view in <body> tag: I want to link to the second route. <%=Html.RouteLink("Link", new { universe = "MyUniverse" })%> Shouldn't this generate a link to the second route in Global.asax? The generated url from the above is: h**p://localhost:53235/test/home/index?universe=MyUniverse. I can only get it to work, if I specify the name of the route: <%=Html.RouteLink("Link", "default", new { universe = "MyUniverse" })%> Am I missing something?

• Google bot .net and AspxAutoDetectCookieSupport dilemma

  - by nLL

  Hi, i have a .net mobile web site where i use sesion state and due to nature of mobile networks/phones (not all supports session cookies) i had to use <sessionState cookieless="AutoDetect"/> It works fine but because each new session redirected with "AspxAutoDetectCookieSupport=1" i have a feeling that google won't like this. Here is a small sample from my server logs supportForumReadTopic.aspx id=38 80 - 66.249.71.80 Mozilla/5.0+(compatible;+Googlebot/2.1;++http://www.google.com/bot.html) 302 supportForumReadTopic.aspx id=38&AspxAutoDetectCookieSupport=1 Mozilla/5.0+(compatible;+Googlebot/2.1;++http://www.google.com/bot.html) 200 As you see each new hit from google will get 302 to itself. I have a genericmozilla5.browser file where i define google bot as cookie supporting browser in order to get .net not to use cookieless urls but not sure how this 302 would effect me. Any one had smilar exprience? Any ideas? Suggestions? Thanks

• $().mouseMove <-- Empty selector in jQuery 1.4

  - by Matrym

  The following bit of code breaks in the upgrade to jquery 1.4: $().mousemove( function (e) { defaults.mouseX = e.pageX; defaults.mouseY = e.pageY; }); }; What appeared to be a reasonable fix was adding "html" as the selector, ex: $("html"). The fix works fine - except now when the user mouses off the page, it doesn't register the mouse position beyond the boundaries. When attempting to use the mouse position for a drag, for example, the amount of movement beyond the screen is really important. Anyone got any ideas? Thanks in advance.

• Ajax doesn't trigger a change-event on a webkit based browser

  - by user319464

  I have adapted a Jquery plugin to for-fill my needs to send GET requests to servers as a way of "pinging" them. I've also added some javascript code to add some fancy features like: depending on the changed value in a that the Jquery plugin changes, it changes the Icon accordingly. To make it all work essentially, I made so that when Ajax gets a "complete" event, it forces a "onChange" event to the span, triggering the javascript validation function to change the status icons. Here is the code of my slightly modified jQuery Plugin: /** * ping for jQuery * * Adapted by Carroarmato0 (to actually work instead of randomly "pinging" nowhere instead of faking * * @auth Jessica * @link http://www.skiyo.cn/demo/jquery.ping/ * */ (function($) { $.fn.ping = function(options) { var opts = $.extend({}, $.fn.ping.defaults, options); return this.each(function() { var ping, requestTime, responseTime ; var target = $(this); var server = target.html(); target.html('<img src="img/loading.gif" alt="loading" />'); function ping() { $.ajax({url: 'http://' + server, type: 'GET', dataType: 'html', timeout: 30000, beforeSend : function() { requestTime = new Date().getTime(); }, complete : function() { responseTime = new Date().getTime(); ping = Math.abs(requestTime - responseTime); if (ping > 2000) { target.text('niet bereikbaar'); } else { target.text(ping + opts.unit); } target.change(); } }); } ping(); opts.interval != 0 && setInterval(ping,opts.interval * 1000); }); }; $.fn.ping.defaults = { interval: 3, unit: 'ms' }; })(jQuery); target.change(); is the code that triggers the "onchange" event in the span: echo " <td class=\"center\"><span id=\"ping$pingNb\" onChange=\"checkServerIcon(this)\" >" .$server['IP'] . "</span></td>"; In Firefox this works, checkServerIcon(this) gets executed and passes the span object to the function. function checkServerIcon(object) { var delayText = object.innerHTML; var delay = delayText.substring(0, delayText.length - 2); if ( isInteger(delay) ) { object.parentNode.previousSibling.parentNode.getElementsByTagName('img')[0].src = 'img/servers/enable_server.png'; } else { if (delay == "bezig.") { object.parentNode.previousSibling.parentNode.getElementsByTagName('img')[0].src = 'img/servers/search_server.png'; } else { object.parentNode.previousSibling.parentNode.getElementsByTagName('img')[0].src = 'img/servers/desable_server.png'; } } } My guess would be that there's something different in WebKit browsers in the way object.parentNode.previousSibling.parentNode. .... works...

• Customizing RadioSelect

  - by Kugel

  Hello I have a form with ChoiceField whose widget is set to RadioSelect Now to override default html output one needs to subclass RadioFieldRenderer like this: class SimpleRadioFieldRenderer(forms.widgets.RadioFieldRenderer): def render(self): """Outputs widget without <ul> or <li> tags.""" return mark_safe(u'\n'.join([u'%s' % force_unicode(w.tag()) for w in self])) All is good now except I'd like to be able to render 1 radio button at a time from template. Something like this: {{ form.myfield.0 }}} Or perhaps hanging it onto widget itself: {{ form.myfield.field.widget.0 }} What bugs me is that RadioFieldRenderer already implements __get_item__ to get just one RadioInput. The problem is that the renderer does not contain data, neither does the widget. And I'd really hate to mess with Field and BoundField. I need this to inject html before/after each radiobutton and I'd like it to be done in the template. From the code it would be easy. Any ideas are welcome.

• Cannot Extend Django 1.2.1 Admin Template

  - by jcady

  I am attempting to override/extend the header for the Django admin in version 1.2.1. However when I try to extend the admin template and simply change what I need documented here: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-vs-replacing-an-admin-template), I run into a recursion problem. I have an index.html file in my project's templates/admin/ directory that starts with {% extends "admin/index.html" %} But it seems that this is referencing the local index file (a.k.a. itself) rather than the default Django copy. I want to extend the default Django template and simply change a few blocks. When I try this file, I get a recursion depth error. How can I extend parts of the admin? Thanks.

• Pushing data once a URL is requested

  - by Eli Grey

  Given, when a user requests /foo on my server, I send the following HTTP response (not closing the connection): Content-Type: multipart/x-mixed-replace; boundary=----------------------- ----------------------- Content-Type: text/html <a href="/bar">foo</a> When the user clicks on foo (which will send 204 No Content so the view doesn't change), I want to send the following data in the initial response. ----------------------- Content-Type: text/html bar How would could I get the second request to trigger this from the initial response? I'm planning on possibly creating a fancy [engines that support multipart/x-mixed-replace (currently only Gecko)]-only email webapp that does server-push and Ajax effects without any JavaScript, just for fun.

• Drupal 6 / Views2 Grid style: whole cells link to nodes

  - by jackocnr

  I have a Users page, which is simply a nicely styled grid (HTML table) of users. I'm displaying a few fields for each one, and both the name and the profile picture have been set to link to the user node. What is the best way to change it so that the whole cell (HTML td) links to the user node? Would you have to use javascript? I've looked into modifying the theme of the view (over-riding the Style output e.g. views-view-grid--users.tpl.php), but cant see an elegant way to get the URL of the user node. And I think you would have to use javascript anyway to turn a whole block element into a link.

• What process does professional website building follow?

  - by Sivvy

  I've searched for a while, but I can't find anything related on Google or here. Me and some friends were debating starting a company, so I figure it might be good to do a quick pilot project to see how well we can work together. We have a designer who can do HTML, CSS and Flash, enjoys doing art, but doesn't like to do HTML and CSS... And 2 programmers that are willing to do anything. My question is, from an experienced site builder's perspective, what steps do we do - in chronological order - to properly handle a website? Does the designer design the look and feel of the site, then the programmers fill in the gaps with functionality? Or do the programmers create a "mock-up" of the site with most of the functionality, then the designer spices it up? Or is it more of a back-and-forth process? I just want to know how a professional normally handles it.

• How do I load content with ujs, jquery and rails?

  - by Joseph Silvashy

  I'm trying to figure out the best way to insert content into a light box using rails UJS. I have a link that looks like this: <%= link_to "login", login_path, :remote => true %> Which produces html as such: <a data-remote="true" href="/login">login</a> So this all works great, and I've created the view file: user_sessions/new.js.erb which also loads just fine, but my question what is the preferred method of inserting appending the html into the page? Like I already have the login form on the non-js page, so can't I just load that partial into the page? Any ideas would be very welcomed.
