  • Chrome extension - Localstorage not working

    - by Bjarki Jonasson
    I'm writing a Chrome extension that uses a content script to modify certain parts of a website. The content script worked fine until I tried to add an options page to my extension. Right now I'm using an options.html file to save user preferences to localstorage, as you can see here: <html> <head><title>Options</title></head> <script type="text/javascript"> function save_options() { var select = document.getElementById("width"); var width = select.children[select.selectedIndex].value; localStorage["site_width"] = width; } function restore_options() { var fwidth = localStorage["site_width"]; if (!fwidth) { return; } var select = document.getElementById("width"); for (var i = 0; i < select.children.length; i++) { var child = select.children[i]; if (child.value == fwidth) { child.selected = "true"; break; } } } </script> <body onload="restore_options()"> Width: <select id="width"> <option value="100%">100%</option> <option value="90%">90%</option> <option value="80%">80%</option> <option value="70%">70%</option> </select> <br> <button onclick="save_options()">Save</button> </body> </html> I also have a background.html file to handle the communication between the content script and the localstorage: <html> <script type="text/javascript"> chrome.extension.onRequest.addListener(function(request, sender, sendResponse) { if (request.method == "siteWidth") sendResponse({status: localStorage["site_width"]}); else sendResponse({}); }); </script> </html> Then there's the actual content script that looks like this: var Width; chrome.extension.sendRequest({method: "siteWidth"}, function(response) { width = response.status; }); None of that code actually works. It looks solid enough to me but I'm not a very experienced programmer so I might be wrong. Could someone explain localstorage to me in layman's terms?

  • manipulate content inserted by ajax, without using the callback

    - by Cody
    I am using ajax to insert a series of informational blocks via a loop. The blocks each have a title, and long description in them that is hidden by default. They function like an accordion, only showing one description at a time amongst all of the blocks. The problem is opening the description on the first block. I would REALLY like to do it with javascript right after the loop that is creating them is done. Is it possible to manipulate elements created ofter an ajax call without using the callback? <!-- example code--> <style> .placeholder, .long_description{ display:none;} </style> </head><body> <script> /* yes, this script is in the body, dont know if it matters */ $(document).ready(function() { $(".placeholder").each(function(){ // Use the divs to get the blocks var blockname = $(this).html(); // the contents if the div is the ID for the ajax POST $.post("/service_app/dyn_block",'form='+blockname, function(data){ var divname = '#div_' + blockname; $(divname).after(data); $(this).setupAccrdFnctly(); //not the actual code }); }); /* THIS LINE IS THE PROBLEM LINE, is it possible to reference the code ajax inserted */ /* Display the long description in the first dyn_block */ $(".dyn_block").first().find(".long_description").addClass('active').slideDown('fast'); }); </script> <!-- These lines are generated by PHP --> <!-- It is POSSIBLE to display the dyn_blocks --> <!-- here but I would really rather not --> <div id="div_servicetype" class="placeholder">servicetype</div> <div id="div_custtype" class="placeholder">custtype</div> <div id="div_custinfo" class="placeholder">custinfo</div> <div id="div_businfo" class="placeholder">businfo</div> </body>

    I have the following lines of JQUERY: // When dragging ends stop: function(event, ui) { // Replace the placeholder with the original $placeholder.after( $this.show() ).remove(); // Run a custom stop function specitifed in the settings settings.stop.apply(this); }, I don't want settings.stop.apply(this); to run UNTIL the line above is $placeholder.after( $this.show() ).remove();, right now what's happening is the settings.stop is running to early. With JQUERY, how can I Sequence these two lines to not proceed until the first is complete? Thanks

  • C++ DLL Export: Decorated/Mangled names

    - by Bob
    Created basic C++ DLL and exported names using Module Definition file (MyDLL.def). After compilation I check the exported function names using dumpbin.exe I expect to see: SomeFunction but I see this instead: SomeFunction = SomeFunction@@@23mangledstuff#@@@@ Why? The exported function appears undecorated (especially compared to not using the Module Def file), but what's up with the other stuff? If I use dumpbin.exe against a DLL from any commercial application, you get the clean: SomeFunction and nothing else......

  • Expanding / grow a JQuery element selection?

    - by HipHop-opatamus
    In the Jquery example below, I would like to expand $(this) before it is cloned, so it includes everything contained in the parent class "comment". How do I do this? I've tried using ReplaceWith($(this).parent('.comment').clone()... and it does not work! $(document).ready( function(){ $('.forumthreadtitle').siblings().hide(); $('.forumthreadtitle').click( function() { $('#first-post').replaceWith($(this).clone().attr('id','first-post')); });

  • Linker Issues with boost::thread under linux using Eclipse and CMake

    - by OcularProgrammer
    I'm in the process of attempting to port some code across from PC to Ubuntu, and am having some issues due to limited experience developing under linux. We use CMake to generate all our build stuff. Under windows I'm making VS2010 projects, and under Linux I'm making Eclipse projects. I've managed to get my OpenCV stuff ported across successfully, but am having major headaches trying to port my threaded boost apps. Just so we're clear, the steps I have followed so-far on a clean Ubuntu 12 installation. (I've done 2 clean re-installs to try and fix potential library cock-ups, now I'm just giving up and asking): Install Eclipse and Eclipse CDT using my package manager Install CMake and CMake Gui using my package manager Install libboost-all-dev using my package manager So-far that's all I've done. I can create the eclipse project using CMake with no errors, so CMake is successfully finding my boost install. When I try and build through eclipse is when I get issues; The app I'm attempting to build uses boost::asio for some UDP I/O and boost::thread to create worker threads for the asio I/O services. I can successfully compile each module, but when I come to link I get spammed with errors such as: /usr/bin/c++ CMakeFiles/RE05DevelopmentDemo.dir/main.cpp.o CMakeFiles/RE05DevelopmentDemo.dir/RE05FusionListener/RE05FusionListener.cpp.o CMakeFiles/RE05DevelopmentDemo.dir/NewEye/NewEye.cpp.o -o RE05DevelopmentDemo -rdynamic -Wl,-Bstatic -lboost_system-mt -lboost_date_time-mt -lboost_regex-mt -lboost_thread-mt -Wl,-Bdynamic /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_thread-mt.a(thread.o): In function `void boost::call_once<void (*)()>(boost::once_flag&, void (*)()) [clone .constprop.98]': make[2]: Leaving directory `/home/david/Code/Build/Support/RE05DevDemo' (.text+0xc8): undefined reference to `pthread_key_create' /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_thread-mt.a(thread.o): In function `boost::this_thread::interruption_enabled()': (.text+0x540): undefined reference to `pthread_getspecific' make[1]: Leaving directory `/home/david/Code/Build/Support/RE05DevDemo' /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_thread-mt.a(thread.o): In function `boost::this_thread::disable_interruption::disable_interruption()': (.text+0x570): undefined reference to `pthread_getspecific' /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../lib/libboost_thread-mt.a(thread.o): In function `boost::this_thread::disable_interruption::disable_interruption()': (.text+0x59f): undefined reference to `pthread_getspecific' Some Gotchas that I have collected from other StackOverflow posts and have already checked: The boost libs are all present at /usr/lib I am not getting any compile errors for inability to find the boost headers, so they must be getting found. I am trying to link statically, but I believe eclipse should be passing the correct arguments to make that happen since my CMakeLists.txt includes SET(Boost_USE_STATIC_LIBS ON) I'm officially out of ideas here, I have tried doing local builds of boost and a bunch of other stuff with no more success. I even re-installed Ubuntu to ensure I haven't completely fracked the libs directories and links with multiple weird versions or anything else. Any help would be muchly appreciated.

  • mootools fx working except in ie9

    - by Craig
    This is my first attempt with Mootools, so I welcome a critique of the code. I have a dynamic list of images that expand on the 'click" event and contract on the 'mouseout' event. The code works fine in all browsers (FF, Safari, Chrome, even the smartphones) but not in IE9 (JS is enabled) Anyone with similar problem or solution? I plan to use a lightbox effect, downloading a larger & clearer image to the center of the page, instead of just resizing a small image. However, I am hesitant to attempt this, if there is problems with IE9. I have coded three image sizes with the upload commit, so the larger image is available for the lightbox, but, I don't see anything in mootools for a lightbox, or am I missing it? $i = 0; while($i < count($validate)) { <div class="validate"> <div class="validate_image_<?php echo $validate[$i]['validate_type']; ?>"> <div class="validate_image" id="validate_image_wrapper_<?php echo $i; ?>"> <?php if ($validate[$i]['validate_image_filename'] != '') { if (file_exists(UPLOAD_DIR . 'validate_image/' . str_replace('.', '_medium.', $validate[$i]['validate_image_filename']))) { echo '<img src="' . UPLOAD_URL . 'validate_image/' . str_replace('.', '_medium.', $validate[$i]['validate_image_filename']) . '" alt="Listing Image" />'; } else { echo '<img src="' . UPLOAD_URL . 'validate_image/' . str_replace('.', '_large.', $validate[$i]['validate_image_filename']) . '" alt="Listing image" />'; } } else { ?> <img src="/images/no_image_posted_validate.png" alt="no image posted" /> <?php } ?> </div> ... remainder of HTML display code function setupEnlargeImage() { window.myFx = new Fx({ duration: 200, transition: Fx.Transitions.Sine.easeOut }); $$('.validate_image').addEvent('click', function() { window.selectedImage = this.id; myFx.start(1,2.0); }); $$('.validate_image').addEvent('mouseout', function() { window.selectedImage = this.id; myFx.start(1.0,1); }); myFx.set = function(value) { var style = "scale(" + (value) + ")"; $(window.selectedImage).setStyles({ "-webkit-transform": style, "-moz-transform": style, "-o-transform": style, "-ms-transform": style, transform: style }); } }

  • Escape SQL "LIKE" value for Postgres with psycopg2

    - by Evgeny
    Does psycopg2 have a function for escaping the value of a LIKE operand for Postgres? For example I may want to match strings that start with the string "20% of all", so I want to write something like this: sql = '... WHERE ... LIKE %(myvalue)s' cursor.fetchall(sql, { 'myvalue': escape_sql_like('20% of all') + '%' } Is there an existing escape_sql_like function that I could plug in here? (Similar question to How to quote a string value explicitly (Python DB API/Psycopg2), but I couldn't find an answer there.)

  • MooTools event listener disappears after element.innerHTML is changed

    - by acoder
    Hi everyone, I am trying to achieve this task using MooTools. Description: I attached an event listener to "myButton" link. A click on this link initiates an AJAX request and updates "myDiv" content based on the response text. During this request a POST variable is being sent to "button.php", but it's not used at the moment.. (i wish to use it later) OK, as a result, "myDiv" gets exactly the same link with the same ID (myButton) + a random number, so that we could see that each click generates a new number. The problem: After the first click on "myButton", "myDiv" updates correctly, showing a random number. When I click "myButton" for the second time (this time in newly updated div), the div does not refresh anymore. Please note that I need "myButton" to be inside "myDiv", and "myDiv" must be updated (refreshed) after each click without having to refresh the entire page. Can somebody show me how to achieve this task based on this simplified code example? index.html <html> <head> <script type="text/javascript" src="mootools-1.2.4-core-nc.js"></script> <script> window.addEvent('domready', function() { $('myButton').addEvent('click', function(e) { e.stop(); var myRequest = new Request({ method: 'post', url: 'button.php', data: { action : 'test' }, onRequest: function() { $('myDiv').innerHTML = '<img src="images/loading.gif" />'; }, onComplete: function(response) { $('myDiv').innerHTML = response; } }); myRequest.send(); $('myButton').removeEvent('click'); }); }); </script> </head> <body> <div id="myDiv"> <a id="myButton" href="#">Button</a> </div> </body> </html> button.php <a id="myButton" href="#">Button</a> clicked <?php echo rand(1,100); ?>

  • Create a timer countdown using hours, minutes & seconds from a future date

    - by Tommy Coffee
    I am using some code I found on the internet that creates a countdown from a certain date. I am trying to edit the code so that it only gives me a countdown from an hour, minute, and second that I specify from a future date. I cannot just have code that counts down from a specified time, I need it to countdown to a specified date in the future. This is important so that if the browser is refreshed the countdown doesn't start over but continues where left off. I will be using cookies so the browser remembers what future date was specified when it was first run. Here is the HTML: <form name="count"> <input type="text" size="69" name="count2"> </form> And here is the javascript: window.onload = function() { //change the text below to reflect your own, var montharray=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec") function countdown(yr,m,d){ var theyear=yr; var themonth=m; var theday=d var today=new Date() var todayy=today.getYear() if (todayy < 1000) todayy+=1900; var todaym=today.getMonth() var todayd=today.getDate() var todayh=today.getHours() var todaymin=today.getMinutes() var todaysec=today.getSeconds() var todaystring=montharray[todaym]+" "+todayd+", "+todayy+" "+todayh+":"+todaymin+":"+todaysec futurestring=montharray[m-1]+" "+d+", "+yr var dd=Date.parse(futurestring)-Date.parse(todaystring) var dday=Math.floor(dd/(60*60*1000*24)*1) var dhour=Math.floor((dd%(60*60*1000*24))/(60*60*1000)*1) var dmin=Math.floor(((dd%(60*60*1000*24))%(60*60*1000))/(60*1000)*1) var dsec=Math.floor((((dd%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1) if(dday==0&&dhour==0&&dmin==0&&dsec==1){ document.forms.count.count2.value=current return } else document.forms.count.count2.value= dhour+":"+dmin+":"+dsec; setTimeout(function() {countdown(theyear,themonth,theday)},1000) } //enter the count down date using the format year/month/day countdown(2012,12,25) } I am sure there is superfluous code above since I only need an hour, minute, and second that I would like to pass to the countdown() function. The year, month and day is unimportant but as I said this is code I am trying to edit which I found on the internet. Any help would be very appreciated. Thank you!
