  • Use jQuery on a variable instead on the DOM ? [solved]

    - by Stef
    In jQuery you can do : $("a[href$='.img']").each(function(index) { alert($(this).attr('href')); } I want to write a jQuery function which crawls x-levels from a website and collects all hrefs to gif images. So when I use the the get function to retrieve another page, $.get(href, function(data) { }); I want to be able to do something like data.$("a[href$='.img']").each(function(index) { }); Is this possible ? ...UPDATE... Thanks to the answers, I was able to fix this problem. function FetchPage(href) { $.ajax({ url: href, async: false, cache: false, success: function(html){ $("#__tmp__").append("<page><name>" + href + "</name><content>" + html + "</content></page>"); } }); } See this zip file for an example how to use it.

  • Parse and Break: why break cannot be used for getting out of "any" or "some" rule ?

    - by Rebol Tutorial
    Let say I have to parse a hierarchical set of tags <tag> <subtag1 attr1=value1 attr2=value2> <subtag1 attr1=value1 attr2=value2> <subtag1 attr1=value1 attr2=value2> </tag> Why can't I use break inside some or any to get out of a level hierarchy ? This would allow to do that kind of parsing instead of having a headache to do so ? I'm asking this because I read here http://www.codeconscious.com/rebol/parse-tutorial.html it would create an infinite loop This case produces an infinite loop. Because the BREAK is within a sub-rule of the rule that SOME is processing. The BREAK does not affect success/failure status or the input pointer - it just exits a rule early: rule-to-break: [(print "Break") break] == [(print "Break") break] parse "X" [some [rule-to-break] "X"] Break *Break* ... Break *Break*(escape)

  • Paging with jQuery

    - by zurna
    I get data from another page using jQuery get method. But I have a small problem. Sometimes, data that I take from another page is too long so it's divided into pages. When the user clicks on 1, 2, 3, ... links he/she is redirected to the other page. However, I want data to be reloaded on the same page. Edit $('ul.thumbs li.pagination a').live('click', function() { var pageNumber = parseInt($(this).text().replace(/[^0-9]/g, '')); $.ajax({ type: "GET", url: "images.cs.asp?Process=ViewImages&PAGEID=<%=Request.QueryString("PAGEID")%>", success: function(data) { $("#ViewImages").html(data); }, error: function (XMLHttpRequest, textStatus, errorThrown) { $("#ViewImages").html('.'); } }); return false; });

  • Facebook Open Graph Debugger Error

    - by Darshanjit Badrain
    Hi I am new to programming and have tried to make a facebook app with open graph beta tutorial. I have done exactly as described in the tutorial but when i try to use the debug tool it gives me an error: Extraneous Property: Objects of this type do not allow properties named og:app_id. I have noticed and searched that its doing this because the tag needs to be <fb:app_id>. I checked my file it says fb:app_id only, but the raw data that pulls up on the debug tool shows meta property="og:app_id" content="267029796703617" even though i have changed and uploaded with fb:app_id. I have checked my page several times and tried some possible solutions but have had no success. Can someone help me fix this.

  • Is there away to load a page only once with AJAX?

    - by digitup
    I have an AJAX call to load a function once the page is loaded, the function opens a lightbox a like frame with some data. The issue is that if I click on close (lightbox frame), the page loads again and again loading the frame so the use never reaches the page under the layer of frame since the frame load on infinite loop. The Ajax is repeating calling the function I guess but I would like to load the frame once and when the user clicks X (close) he may return to the original page. $(document).ready(function(){ var city = $('#citycode').html(); $.ajax({ //when page is loaded, fire the following function success: function(){ //the function to be fired located in the page in seperate file openX(city + //some other parameters); }}); }); Any tips?

  • What happens when I MPI_Send to a process that has finished?

    - by nieldw
    What happens when I MPI_Send to a process that has finished? I am learning MPI, and writing a small sugar distribution-simulation in C. When the factories stop producing, those processes end. When warehouses run empty, they end. Can I somehow tell if the shop's order to a warehouse did not succeed(because the warehouse process has ended) by looking at the return value of MPI_Send? The documentation doesn't mention a specific error code for this situation, but that no error is returned for success. Can I do: if (MPI_Send(...)) { ... /* destination has ended */ ... } And disregard the error code? Thanks

  • Empty Post with JQuery Ajax Post

    - by chandru
    Hi, I am getting a some unusual problem with JQuery ajax. I am using IIS to host my web application and I have http handler for which I have enabled only POST verb on it. Using JQuery ajax, I am posting data to this http handler, this is working fine in our development and testing environment and also most of the time on production environment as well. But sometimes we are getting empty post data on to the server. When we look into the csBytes on IISLog we found that it was very less compare to other success post requests. We are using JSON.js to convert the javascript object back to raw json string and latest jquery.1-3.js for posting to server. Anbody know why this is happening?

  • How do I pass object values with render :action => 'new'

    - by PlanetMaster
    Hi, In an app I have the following: def new @property = Property.new(:country_id => 1, :user_id => current_user.id, :status_id => 'draft') end def create @property = Property.new(params[:property]) if @property.save flash[:success] = t('The_property_is_successfully_created') redirect_to myimmonatie_url else flash.now[:error]=t("The_property_could_not_be_created") render :action => 'new' end end When an error accors, the line render :action = 'new' gets executed, but the my form gives an error: user blank country blank These cannot be blank (defined in model), meaning this code: @property = Property.new(:country_id => 1, :user_id => current_user.id, :status_id => 'draft') is not executed anymore. What is the reason and solution? Thanks!

  • .NET's double.NaN - how does this counterintuitive feature work?

    - by GeReV
    I stumbled upon the definition of double.NaN in code: public const double NaN = (double)0.0 / (double)0.0; This is done similarly in PositiveInfinity and NegativeInfinity. double.IsNaN (with removing a few #pragmas and comments) is defined as: [Pure] [ReliabilityContract(Consistency.WillNotCorruptState, Cer.Success)] public static bool IsNaN(double d) { if (d != d) { return true; } else { return false; } } This is, by far, the most counterintuitive thing I have ever seen in the .NET framework. How is 0.0 / 0.0 represented "behind the scenes"? How can division by 0 be possible in double, and why does NaN != NaN?

  • Proper mechanism for sending PHP errors to the client

    - by Chris
    Greetings, I was trying to discover a proper way to send captured errors or business logic exceptions to the client in an Ajax-PHP system. In my case, the browser needs to react differently depending on whether a request was successful or not. However in all the examples I've found, only a simple string is reported back to the browser in both cases. Eg: if (something worked) echo "Success!"; else echo "ERROR: that failed"; So when the browser gets back the Ajax response, the only way to know if an error occurred would be to parse the string (looking for 'error' perhaps). This seems clunky. Is there a better/proper way to send back the Ajax response & notify the browser of an error? Thank you.

    - by Alex Isayko
    Hello to all! I am writing a small Django application and I should be able to create for each model object its periodical task which will be executed with a certain interval. I'm use for this a Celery application, but i can't understand one thing: class ProcessQueryTask(PeriodicTask): run_every = timedelta(minutes=1) def run(self, query_task_pk, **kwargs): logging.info('Process celery task for QueryTask %d' % query_task_pk) task = QueryTask.objects.get(pk=query_task_pk) task.exec_task() return True Then i'm do following: >>> from tasks.tasks import ProcessQueryTask >>> result1 = ProcessQueryTask.delay(query_task_pk=1) >>> result2 = ProcessQueryTask.delay(query_task_pk=2) First call is success, but other periodical calls returning the error - TypeError: run() takes exactly 2 non-keyword arguments (1 given) in celeryd server. So, can i pass own params to PeriodicTask run() ? Thanks!

    - by Kyle
    I am trying to do an Ajax request for an ICS file. Yeah, I know it sounds crazy, but I found the perfect library to parse the iCal data. Any ideas why the data comes up blank when I do this? $.ajax({ success:function(data){ alert(data); }, url:"http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=15714&cat=98&platform=osx&method=sa/Swiss32Holidays.ics" }); It makes the request fine, but the data still comes up blank.

  • jQuery AJAX & an ASP.NET web service works locally but not remotely

    - by Alex
    Interesting one here. I have an ASP.NET 1.1 project that contains a web service in it. I'm using jQuery's AJAX functionality to call some services from the client. This is what my code looks like: $.ajax({ type: "POST", url: 'foo.asmx/functionName', data: 'foo1=' + foo1 + '&foo2=' + foo2, dataType: "xml", success: function(xml) { //do something with my xml data }, error: function(request, error){ //handle my error } }); This works great when I run the site from my IDE on localhost. However, when I deploy this site to any other server I get a parsererror error from jQuery. It does not appear to even call my service as I dropped in some code to write a log file to disk and it's not making it there. The same exact XML should be returned from both my localhost and the server I deployed to. Any ideas?

  • Python change the working directory for an exe opened with startfile

    - by Saulpila
    In python i'm using the os.startfile command to start a windows executable that does especific stuff in its own folder, the python code is running from another folder, so when I start the file, it starts in the python script's working directory, but it has to start in its own directory. I've tried to use os.chdir(path) to change the working directory, but it fails, the file still not runs in it's own folder. I thought maybe there is a command like shortcut's "Start in" line. I've searched everywere, but not success. The only solution comes to my mind is to create a shortcut and add the "start in" line, then launch the shortcut, but that is very impractical.

  • How to log the raw SQL from Oracle occi C++ api?

    - by savanna
    One of our customers is complaining our application is not working. Their reasoning is that our sql function call to their Oracle database is not getting the "expected" result. Sometime, it should failed but our application get success from their database. It's really frustrating because it's their database and we cannot do any test on it. We are using the C++ Oracle OCCI API. Is there anyway we can log the raw sql from our end? That will be very helpful and we can ship the script to them and let them debug in their system to figure out the problem. Thanks in advance.

    Hi! I toyed around with .load() and .ajax(), but i didn't get to an end. Here's what I need: Everey minute the function shall check if it can load a certain page. if the connection succeeds, I want the page to be refreshed, if not, nothing shall happen, the script shall retry later.

  • JQUERY AJAX, Issues with spaces being sent to the server, Why?

    - by nobosh
    I'm using the following code to post to the server which is then sent to a MYSQL query to find matches via search. $.ajax({ url: '/search/spotlight/', data: "q=" + $(this).val(), success: function(data) { } }); When Q's val has spaces in it, it's creating problems. I'm wondering if I'm handling this correctly? Do I need to encode the value in the AJAX call? Or is this a problem on my backend, which is ColdFusion Right now JQUERY is posting the following to the server: /search/spotlight/?q=FirstName%20LastName is this right?
