  • Using Jquery and Ajax in ASP.NET

    - by xkcd
    I am using ajax and jquery to load contents into a div. My jquery looks like this $("a.trigger").click(function() { $.ajax({ type: "POST", url: "GetStuff.aspx", data: "id=0", success: function(response){ $("#contentDiv").html(response); } }); }); In GetStuff.aspx I would like to write some asp.net html controls like private void Page_Load(object sender, System.EventArgs e) { Response.Expires = -1; Response.ContentType = "text/plain"; Response.Write("<asp:Label id=\"label1\" runat=\"server\" text=\"helloworld\"/>"); Response.End(); } However the label does not appear on the page. I tried to put the asp:Label in my aspx file like this <%@ Page Language="C#" Inherits="Untitled.GetStuff" %> <asp:Label id="label12" runat="server" text="helloworld2"/> It also does not work. How can I get asp.net html controls to show up?

  • is there a rule in CSS that says class="one two" vs class="two one" and the second will override the

    - by Jian Lin
    Right now, there seems to be no such effect. Example: both divs are orange in color on Firefox <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <style> .one { border: 6px dashed green } .two { border: 6px dashed orange } </style> </head> <body> <div class="one two"> hello world </div> <div class="two one"> hello world </div>

  • SSI not producing output, not giving error either.

    - by bstullkid
    in the html file: <!--#exec cgi="/cgi-bin/test.pl"--> the perl script: #!/usr/bin/perl print "Content-Type: text/html\n\n"; print "<input type=\"hidden\" name=\"aname\" value=\"avalue\">\n"; print "<img src=\"/cgi-bin/script.pl\" />"; This does not give me an 'error processing directive' error, nor does it output my HTML inplace of the tag. I'll also add that the ssi tag gets replaced with nothing.

  • Need help getting DIV inside DIV to stretch to width of contents in Firefox

    - by bj.
    I am using a layout similar to the one from Dynamic Drive here: http://www.dynamicdrive.com/style/layouts/item/css-right-frame-layout/ The main content area (white) has overflow set to auto. I have given the innerTube inside this main content area a border. However if the contents within this innerTube are greater than the width of the main content area, a horizontal scroll bar will appear as expected, but in Firefox these contents will 'overlap' the border and go off screen (can be retrieved by scrolling horizontally). In other words, the right hand border remains in place, and the content just goes over the op of it, and disappears behind the right hand column. In IE it behaves exactly as I want - the content pushes the border off screen to be visible only once you scroll over there. I guess the easiest thing is to paste the source code here. If you copy it into a blank file you'll see what I mean. I've just used one really long word to replicate what happens if a wide image is there instead. Thanks in advance to anyone who can help me out. <!--Force IE6 into quirks mode with this comment tag--> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <style type="text/css"> body{ margin: 0; padding: 0; border: 0; overflow: hidden; height: 100%; max-height: 100%; } #framecontent{ position: absolute; top: 0; bottom: 0; right: 0; width: 200px; /*Width of frame div*/ height: 100%; overflow: hidden; /*Disable scrollbars.

  • Faking user interaction on CMS

    - by Leocer
    I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.

  • Getting 'this' pointer inside dependency property changed callback

    - by mizipzor
    I have the following dependency property inside a class: class FooHolder { public static DependencyProperty CurrentFooProperty = DependencyProperty.Register( "CurrentFoo", typeof(Foo), typeof(FooHandler), new PropertyMetadata(OnCurrentFooChanged)); private static void OnCurrentFooChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { FooHolder holder = (FooHolder) d.Property.Owner; // <- something like this // do stuff with holder } } I need to be able to retrieve a reference to the class instance in which the changed property belongs. This is since FooHolder has some event handlers that needs to be hooked/unhooked when the value of the property is changed. The property changed callback must be static, but the event handler is not.

  • htaccess rewriterule

    - by user322731
    I currently have this rule where I want the page to just render my static content. RewriteRule ^videos\/coverage\/view\/236159\-([0-9a-zA-Z-]+) http: //website.com/static/236159.html [NC] However, this doesn't work. It works with a L tag but then the URL is different: RewriteRule ^videos\/coverage\/view\/236159\-([0-9a-zA-Z-]+) http: //website.com/static/236159.html [L, NC] My goal is to keep the URL the same but the content different. Can anyone point out to what flags are needed in order to get this working properly? Thanks!

  • How to manage db connections on server?

    - by simpatico
    I have a severe problem with my database connection in my web application. Since I use a single database connection for the whole application from singleton Database class, if i try concurrent db operations (two users) the database rollsback the transactions. This is my static method used: All threads/servlets call static Database.doSomething(...) methods, which in turn call the the below method. private static /* synchronized*/ Connection getConnection(final boolean autoCommit) throws SQLException { if (con == null) { con = new MyRegistrationBean().getConnection(); } con.setAutoCommit(true); //TODO return con; } What's the recommended way to manage this db connection/s I have, so that I don't incurr in the same problem.

  • jQuery AJAX get request - cannot see returned data

    - by Wes
    I think I am missing something obvious here, but I can't figure it out. I expect the following HTML to alert a response from the server. But, the alert is empty. I can see in Wireshark that the expected response is coming back to me from the server. Why is it not populated in the data variable? <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> </head> <body> <script type="text/javascript"> $.get("http://www.geocommunicator.gov/TownshipGeocoder/TownshipGeocoder.asmx/GetTRS", {'Lat': 41, 'Lon': -93, 'Units': 'eDD', 'Datum': ''}, function(data) { alert('data:'+data); }); </script> </body> </html>

  • NSString stringWithContentsOfFile failing with what seems to be the wrong error code

    - by deanWombourne
    Hello. I'm trying to load a file into a string. Here is the code I'm using: NSError *error = nil; NSString *fullPath = [[NSBundle mainBundle] pathForResource:filename ofType:@"html"]; NSString *text = [NSString stringWithContentsOfFile:fullPath encoding:NSUTF8StringEncoding error:&error]; When passed in @"about" as the filename, it works absolutely fine, showing the code works. When passed in @"eula" as the filename, it fails with 'Cocoa error 258', which translates to NSFileReadInvalidFileNameError. However, if I swap the contents of the files over but keep the names the same, the other file fails proving there is nothing wrong with the filename, it's something to do with the content. The about file is fairly simple HTML but the eula file is a massive mess exported from Word by the legal department. Does anyone know of anything inside a HTML file that could cause this error to be raised? Much thanks, Sam

  • Should I create protected constructor for my singleton classes?

    - by Vijay Shanker
    By design, in Singleton pattern the constructor should be marked private and provide a creational method retuning the private static member of the same type instance. I have created my singleton classes like this only. public class SingletonPattern {// singleton class private static SingletonPattern pattern = new SingletonPattern(); private SingletonPattern() { } public static SingletonPattern getInstance() { return pattern; } } Now, I have got to extend a singleton class to add new behaviors. But the private constructor is not letting be define the child class. I was thinking to change the default constructor to protected constructor for the singleton base class. What can be problems, if I define my constructors to be protected? Looking for expert views....

  • use callback function to report stack backtrace

    Assume I have the following: typedef struct { char *name; char binding; int address; } Fn_Symbol //definition of function symbol static Fn_Symbol *fnSymbols; //array of function symbols in a file statc int total; //number of symbol functions in the array and file static void PrintBacktrace(int sigum, siginfo_t * siginfo, void *context) { printf("\nSignal received %d (%s)\n", signum, strsignal(signum)); const int eip_index = 14; void *eip = (void *)((struct ucontext *)context)->uc_mcontext.gregs[eip_index]; printf("Error at [%p] %s (+0x%x), eip, fnName, offset from start); //????? exit(0); } I have this so far, but what is the best way using the fnSymbols static global pointer to identify the function where the error occured and then back trace through the stack to identify each calling function by address, name, and offset?

  • Does urllib2.urlopen() actually fetch the page?

    - by beagleguy
    hi all, I was condering when I use urllib2.urlopen() does it just to header reads or does it actually bring back the entire webpage? IE does the HTML page actually get fetch on the urlopen call or the read() call? handle = urllib2.urlopen(url) html = handle.read() The reason I ask is for this workflow... I have a list of urls (some of them with short url services) I only want to read the webpage if I haven't seen that url before I need to call urlopen() and use geturl() to get the final page that link goes to (after the 302 redirects) so I know if I've crawled it yet or not. I don't want to incur the overhead of having to grab the html if I've already parsed that page. thanks!

  • Rails and jQuery - how do you get server-side validation errors to your view after an ajax request

    - by adam
    Ive searched this site but questions are usually regarding doing client-side validations or for different frameworks. I have a tasks list whose items can be edited inline. Upon submitting the inline edit form the item is updated all thanks to jQuery, ajax and rails. But I want to handle bad input from the user. HTML requests redisplay the view and errors are displayed thanks to rails helpers. But how do I insert that information after an ajax call? Heres my update method in my controller def update @task = Task.find(params[:id]) respond_to do |format| if @task.update_attributes(params[:task]) flash[:notice] = 'Task was successfully updated.' format.html { redirect_to(@task) } format.xml { head :ok } format.js else format.html { render :action => "edit" } format.xml { render :xml => @task.errors, :status => :unprocessable_entity } #format.js ...hmmm... either go to js.erb file or do stuff inline end end end

  • Online Code Coloring Service

    - by Sarfraz
    Hello, I would like to know if anyone knows of an online service where we paste the code and it generates back the colored html source code for that code. It could be PHP, HTML, CSS, Javascript, C, Java. Idea is that once i have the colored html code, i could easily put that in my wordpress.com blog. I know about [sourcecode language="whatever"] but just wanted to know an online service that supports multiple languages. The benefit is that, i can choose any color style/theme from that online service for my code. Thanks.

  • grunt angularjs doesn't process video files

    - by Daly
    I've set up my grunt file to copy, minify, uglify, revved and all that. It works fine with all media I use, except that recently I added a video to an html file, but it's not being copied to /dist, nor is the html being updated with the versioned file (that is not being copied nor revved). Not sure what I'm missing. Here is the html fragment: <div class="col-xs-4"> <div class="row flowplayer"> <video autoplay> <source type="video/mp4" src="/videos/wedding_planners_bride_smallweb.mp4"> </video> </div> </div> What do I need to add to my gruntfile.js file to process /videos the same way /images are just working out of the box? Thanks

  • Ruby class variable is reset after rails app initialized

    - by Phuong Nguy?n
    I tried to assign a class static variable like this class QueryLogger < Logger @@query_logger_default_instance = nil def self.default_instance # Use global variable because static variable doesn't work @@query_logger_default_instance ||= self.new(STDOUT) end end In initializers folder of my rails app, I added a file with this code block ActiveRecord::Base.logger = QueryLogger.default_instance In a request (action of controller), I make a call to this: QueryLogger.default_instance. My assumption is that the call to default_instance will always report the same. However, it does not. Now I try to watch stuff in NetBeans by setting breakpoint inside default_instance. Thing happen as expected, the default_instance get called twice, one due to the initializer block and one due to the call to my action. Surprising thing is, in both times, @@query_logger_default_instance report nil inside NetBeans inspector. The first nil report is correct, but the second shocked me. It's look like static variable gets reset after rails app initialized. Is there some magic there?

Is there any way for a function in the index file to run from the html document that is loaded inside a element.
