  • JavaScript, jQuery, XML - if statement not executing for unknown reason

    - by Jack Roscoe
    Hi, I have a 'for' loop which extracts data from an XML document and adds it into some JavaScript objects, each time the loop executes I want it to run a certain function depending on the value of the attribute 'typ' which is being retrieved from the xml. Currently, the data from the XML is successfully being parsed, which is proven by the first 'alert' you can see which produces the correct value. However, neither of the 'alert' lines in the 'if' statement lower down are being executed and as a result I cannot test the 'ctyp3' function which is supposed to be called. Where have I gone wrong? for (j=0; j<arrayIds.length; j++) { $(xml).find("C[ID='" + arrayIds[j] + "']").each(function(){ // pass values questions[j] = { typ: $(this).attr('typ'), width: $(this).find("I").attr('wid'), height: $(this).find("I").attr('hei'), x: $(this).find("I").attr('x'), y: $(this).find("I").attr('x'), baC: $(this).find("I").attr('baC'), boC: $(this).find("I").attr('boC'), boW: $(this).find("I").attr('boW') } alert($(this).attr('typ')); if ($(this).attr('typ') == '3') { ctyp3(x,y,width,height,baC); alert('pass'); } else { // Add here alert('fail'); } }); }

  • Firefox handles xxx.submit(), Safari doesn't ... what can be done?

    - by Prairiedogg
    I'm trying to make a pull down menu post a form when the user selects (releases the mouse) on one of the options from the menu. This code works fine in FF but Safari, for some reason, doesn't submit the form. I re-wrote the code using jquery to see if jquery's .submit() implementation handled the browser quirks better. Same result, works in FF doesn't work in safari. The following snippets are from the same page, which has some django template language mixed in. Here's the vanilla js attempt: function formSubmit(lang) { if (lang != '{{ LANGUAGE_CODE }}') { document.getElementById("setlang_form").submit(); } } Here's the jquery attempt: $(document).ready(function() { $('#lang_submit').hide() $('#setlang_form option').mouseup(function () { if ($(this).attr('value') != '{{ LANGUAGE_CODE }}') { $('#setlang_form').submit() } }); }); and here's the form: <form id="setlang_form" method="post" action="{% url django.views.i18n.set_language %}"> <fieldset> <select name="language"> {% for lang in interface_languages %} <option value="{{ lang.code }}" onmouseup="formSubmit('{{ lang.name }}')" {% ifequal lang.code LANGUAGE_CODE %}selected="selected"{% endifequal %}>{{ lang.name }}</option> {% endfor %} </select> </fieldset> </form> My question is, how can I get this working in Safari?

  • About Web service ,how to use Ajax to call a specific member function of a class?

    - by Liu chwen
    I'm trying to build a web service by PHP. In my case, I called the getINFO(), but the return value on client side always null. Have no idea to solve this problem.. Here's the SOAPserver code(WS.WEB_s.php): require("WEB_s.php"); ini_set("soap.wsdl_cache_enabled", 0); $server = new SoapServer('wsdl/WEB_s.wsdl'); $server->setClass("WEB_s"); $server->handle(); Where the main Class is(WEB_s.php): final class WEB_s { public function getINFO(){ $JsonOutput = '{"key":"value",...}'; return $JsonOutput; } public function setWAN($setCommand,$newConfigfilePath){ $bOutput; return $bOutput; } } And Client side: $(document).ready(function(){ $('#qqq').button().click(function(){ var soapMessage = LoginSoap($('#uid').val(),$('#pwd').val()); alert('soapMessage'); $.ajax({ //url: 'libraries/WS.WEB_s.php/WEB_s/getINFO',//success , return null //url: 'libraries/WS.WEB_s.php/', //success , return null url: 'libraries/WS.WEB_s.php/getINFO',//success , return null type: 'GET', timeout: (10* 1000), contentType: "text/xml", dataType: "xml", success: function( data,textStatus,jqXHR){ alert('Server success(' + data+')('+ textStatus + ')(' + jqXHR + ')'); }, error: function (request, status, error) { alert('Server Error(' + status+')->'+error); }, complete: function (jqXHR, textStatus) { alert('Server success(' + jqXHR+')('+ textStatus + ')'); } }); }); }); The following is the corresponding WSDL file : http://codepaste.net/95wq9b

  • HTML form never calls Javascript

    - by user1205577
    I have a set of radio buttons defined in HTML like so: <input type="radio" name="group" id="rad1" value="rad1" onClick="doStuff(this.id)">Option 1<br> <input type="radio" name="group" id="rad2" value="rad2" onClick="doStuff(this.id)">Option 2<br> Just before the </body> tag, I have the following JavaScript behavior defined: <script type="text/javascript"> /*<![CDATA[*/ function doStuff(var id){ alert("Doing stuff!"); } /*]]>*/ </script> When I run the program, the page loads as expected in my browser window and the radio buttons allow me to click them. The doStuff() function, however, is never called (I validated this using breakpoints as well). I also tried the following just to see if inline made the difference, but it seems the JavaScript is never called at all: <script type="text/javascript"> /*<![CDATA[*/ alert("JavaScript called!"); main(); function main(){ var group = document.getElementsByName('group'); for(var i=0; i<group.length; i++){ group[i].onclick = function(){ doStuff(this.id); }; } } /*]]>*/ </script> My question is, is there something special I need to do using HTML and JavaScript in this context? My question is not whether I should be using inline function calls or whether this is your favorite way to write code.

  • Creating a clickable progress bar

    - by Cory
    What I'm essentially building is a webkit based controller that communicates with a program called Ecoute.app. The controller has a progressbar that indicates the progress made through the currently playing song, but I want to make this bar's position adjustable with a click. function barClick() { var progress = Ecoute.playerPosition(); var width = 142.5; var percentElapsed = progress / length; var position = width * percentElapsed; Ecoute.setPlayerPosition(position); } Is what I have, with Ecoute.playerPosition() returning the player's current position. Width has previously been defined as a dynamic value at var width = 142.5 / length * progress + 1.63; With length being the current track length and progress being the player's position. This has been able to dynamically stretch a progression overlay image to indicate the position of the track via the desktop controller. However, the max width used in the second function does not appear to allow the first function to work properly. Any help possibly determining the correct value or approach would be hugely appreciated.

  • Can Boost Program_options separate comma separated argument values

    - by lrm
    If my command line is: > prog --mylist=a,b,c Can Boost's program_options be setup to see three distinct argument values for the mylist argument? I have configured program_options as: namespace po = boost::program_options; po::options_description opts("blah") opts.add_options() ("mylist", std::vector<std::string>>()->multitoken, "description"); po::variables_map vm; po::store(po::parse_command_line(argc, argv, opts), vm); po::notify(vm); When I check the value of the mylist argument, I see one value as a,b,c. I'd like to see three distinct values, split on comma. This works fine if I specify the command line as: > prog --mylist=a b c or > prog --mylist=a --mylist=b --mylist=c Is there a way to configure program_options so that it sees a,b,c as three values that should each be inserted into the vector, rather than one? I am using boost 1.41, g++ 4.5.0 20100520, and have enabled c++0x experimental extensions.

  • What's wrong with output parameters?

    - by Chris McCall
    Both in SQL and C#, I've never really liked output parameters. I never passed parameters ByRef in VB6, either. Something about counting on side effects to get something done just bothers me. I know they're a way around not being able to return multiple results from a function, but a rowset in SQL or a complex datatype in C# and VB work just as well, and seem more self-documenting to me. Is there something wrong with my thinking, or are there resources from authoritative sources that back me up? What's your personal take on this and why? What can I say to colleagues that want to design with output parameters that might convince them to use different structures? EDIT: interesting turn- the output parameter I was asking this question about was used in place of a return value. When the return value is "ERROR", the caller is supposed to handle it as an exception. I was doing that but not pleased with the idea. A coworker wasn't informed of the need to handle this condition and as a result, a great deal of money was lost as the procedure failed silently!

  • jquery suspected naving convention problem

    - by donfigga
    Hi all im having provlem with this jquery function, the protion of the function that renames the id, class and name of the dropdown only works for the first dropdown, susequest ones do not work , any ideas, i suspect it may have something to do with naming convention as in cat.parent_id but it is required for asp.net mvc model binding. $(document).ready(function () { $("table select").live("change", function () { var id = $(this).attr('id'); if ($(this).attr('classname') != "selected") { var rowIndex = $(this).closest('tr').prevAll().length; $.getJSON("/Category/GetSubCategories/" + $(this).val(), function (data) { if (data.length > 0) { //problematic portion $("#" + id).attr('classname', 'selected'); $("#" + id).attr('name', 'sel' + rowIndex); $("#" + id).attr('id', 'sel' + rowIndex); var position = ($('table').get(0)); var tr = position.insertRow(rowIndex + 1); var td1 = tr.insertCell(-1); var td2 = tr.insertCell(-1); td1.appendChild(document.createTextNode('SubCategory')); var sel = document.createElement("select"); sel.name = 'parent_id'; sel.id = 'parent_id'; sel.setAttribute('class', 'unselected'); td2.appendChild(sel); $('#parent_id').append($("<option></option>").attr("value", "-1").text("-please select item-")); $.each(data, function (GetSubCatergories, Category) { $('#parent_id').append($("<option></option>"). attr("value", Category.category_id). text(Category.name)); }); sel.name = 'cat.parent_id'; sel.id = 'cat.parent_id'; } }); } }); });

  • import text file containing line breaks into excel

    - by Maximilian Tyrtania
    I have a plain text file looking like this: "some text containing line breaks" I'm trying to talk excel 2004 (Mac, v.11.5) into opening this file correctly. I'd expect to see only one cell (A1) containing all of the above (without the quotes)... But alas, I can't make it happen, because Excel seems to insist on using the CR's as row delimiters, even if I set the text qualifier to double quote. I was sort of hoping that Excel would understand that those line breaks are part of the value - they are embedded in double quotes which should qualify them as part of the value. So my Excel sheet has 5 rows, which is not what I want. I also tried this Applescript to no avail: tell application "Microsoft Excel" activate open text file filename ¬ "Users:maximiliantyrtania:Desktop:linebreaks" data type delimited ¬ text qualifier text qualifier double quote ¬ field info {{1, text format}} ¬ origin Macintosh with tab end tell If I could tell Excel to use a row delimiter other than CR (or LF), well, I'd be a happy camper, but excel seems to allow the change of the field delimiter only, not the row delimiter. Any pointers? Thanks, Max Excel's open

  • php clean up regex

    - by David
    hey can i clean up a preg_match in php from this: preg_match_all("/(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?(".$this->reg['wat'].")?/",$value,$match); to look like this: preg_match_all("/ (".$this->reg['wat'].")?

(".$this->reg['wat'].")? /",$value,$match); right now each space, it counts as a ling break so it wont return any finds when searching. but it just looks cleaner and easier to read is why i ask you know. i was looking for one of those letters to add after the closing "/" in the regex. thanks

  • How to take a NSString such as, "0+1+2", get the sum of those and create new string. Obj-C

    - by Ace Legend
    Alright. My app has a text field and next to it are two buttons (Plus button and Equals button). When you press the "Plus" button, it takes the text inside of the textField and adds a "+" to it. Code below: - (IBAction)plusButtonPressed:(id)sender { NSString *plusString = @"+"; NSString *inputString = carbsField.text; NSString *outputString = [NSString stringWithFormat:@"%@%@",inputString,plusString]; NSLog(@"%@",outputString); [carbsField setText:outputString]; } I will eventually make that more intelligent so that I can't put two pluses or whatever. Anyway, then I want the equal button to take whatever is in the textField, which should look something like: "23+54+2.2" and get the sum of those values. I believe I know how to take an Integer and make it a String, but I want to verify it: int *value = 56; NSString *string = @"%d",value; Well, if anyone can show me how to do this, I would be very appreciative. Thanks. EDIT At the moment, I have not tried anything. This is because I do not know where to start. I have an idea of what to do, but I do not know how to execute it. I believe I need to get all characters before a "+" convert them into int and then get the sum of some array of those values.

  • Data conversion from accelerometer

    - by mrigendra
    Hi all I am working on an accelerometer bma220 , and its datasheet says that data is in 2's complement form.So what i had to do was getting that 8 bit data in any 8 bit signed char and done. the bma220 have an 8 bit register of which first 6 bits are data and last two are zero. void properdata(int16_t *msgData) { printf("\nin proper data\n"); int16_t temp, i; for(i=0; i<3; i++) { temp = *(msgData + i); printf("temp = %d sense = %d\n", temp, sense); temp = temp >> 2; // only 6 bits data temp = temp / sense; //decimal value * .0625 = value in g printf("temp = %d\n", temp); } } in this program i am taking data in a unsigned variable msgdata and doing all the calculations on a signed variable. I just need to know if this is the correct way to convert data?

  • Migrating MachineKey from iis6 on old server to iis7 on new server

    - by MaseBase
    I am migrating our hosting environment to a totally new data center with new boxes and hardware and software... the whole deal. Our website cookies are encrypted using the machineKey, so when I make a request to my domain and point it to the new web server (by overriding the local hosts file), I get an error because the cookie cannot be decrypted, since the Machine Key is different. I'd like to avoid any problems a frequent user might have when they arrive at the new server for the first time. To the best of my knowledge, at this point I think I need to set the same MachineKey from our current servers on our new servers. This way when past visitors with a cookie arrive at our website served by the new server, the cookie will be decrypted properly with the MachineKey it was encrypted with and then log them in properly. My question is where do I find my MachineKey value (in IIS 6 win2k3 server) so I can use that value to set it statically on my new servers? I've pulled up my machine.config file, but it doesn't specify the key, it only specifies a configSection where the key can be defined. It's not in my web.config for the app or elsewhere. I did find this great article on some MachineKey and Web Garden woes (which could explain some other bugs I've been experiencing with regard to the machineKey). Update I am back to this issue and am still faced with a similar problem. I have the MachineKey auto-generated on the IIS6 server but I need to get that exact key so I can set it explicitly and not have it auto-generated anymore. Any help is appreciated...

  • Same random numbers from instantiated class

    - by user1797202
    I'm learning C# and created a class within my program that holds a random number generator: class RandomNumberGenerator { Random RNG = new Random(); // A bunch of methods that use random numbers are in here } Inside this class are a few methods that use the RNG. Data gets sent here from other parts of the program, gets processed, then gets returned. One of the methods does the following: // Method works something like this int Value1 = RNG.Next(x, y); int Value2 = RNG.Next(x, y); int Value3 = RNG.Next(x, y); The x, y values are to be sent here from another class. So, I have to create an instance of the RandomNumberGenerator within that class so I can call its methods and pass the x and y values to it. class DoStuff { RandomNumberGenerator Randomizer = new RandomNumberGenerator // Here I call a bunch of Randomizer methods that give me values I need } The problem in the above method is that I get the same numbers every time for all three values. I'm not sure if it's because they're so close together and Randomizer's seed value hasn't had time to change or if I'm doing something wrong when I create a new instance of the RandomNumberGenerator class. I've gone through a bunch of answers on here already and typically problems like this are due to people creating many new Random objects when they run methods (thus setting the seed for all of them to the same value), but the only new Random object I create is within the RandomNumberGenerator class. I then instantiate that once within the other class so I can pass it data and use its methods. Why is this happening and how would I fix this?

  • How do I create a polymorphic model with a collection_select?

    - by muxe
    This are my models: class Speaker < ActiveRecord::Base belongs_to :session, :foreign_key => :session_id, :class_name => :Session belongs_to :speakable, :polymorphic => true end class Session < ActiveRecord::Base has_many :speakers accepts_nested_attributes_for :speakers end class Person < ActiveRecord::Base has_many :speakers, :as => :speakable end class Company < ActiveRecord::Base has_many :speakers, :as => :speakable end What I want to do now is something like this: app/views/sessions/edit.html.erb <% f.fields_for :speakers do |sf| %> <p> <%= sf.label :speaker %><br /> <%= sf.collection_select :speakable, Company.all + Person.all, :id, :full_name %> </p> <% end %> But it is not working because of the polymorphic assignment. How do I approach this problem? EDIT: The Error is: undefined method `base_class' for String:Class with params being: "speaker"=>{"speakable"=>"1063885469", "session_id"=>"1007692731"} The value passed to speakable is the id of the Speaker/Company. Yes, this is the value I specified the collection_select to return, but how can I manage to supply both values (speakable_id and speakable_type) ?

  • Java Detect Variable Change Using PropertyChangeSupport and PropertyChangeListener

    - by Sam
    I'm trying to print out debug statements when some third party code changes a variable. For example, consider the following: public final class MysteryClass { private int secretCounter; public synchronized int getCounter() { return secretCounter; } public synchronized void incrementCounter() { secretCounter++; } } public class MyClass { public static void main(String[] args) { MysteryClass mysteryClass = new MysteryClass(); // add code here to detect calls to incrementCounter and print a debug message } I don't have the ability to change the 3rd party MysteryClass, so I thought that I could use PropertyChangeSupport and PropertyChangeListener to detect changes to the secretCounter: public class MyClass implements PropertyChangeListener { private PropertyChangeSupport propertySupport = new PropertyChangeSupport(this); public MyClass() { propertySupport.addPropertyChangeListener(this); } public void propertyChange(PropertyChangeEvent evt) { System.out.println("property changing: " + evt.getPropertyName()); } public static void main(String[] args) { MysteryClass mysteryClass = new MysteryClass(); // do logic which involves increment and getting the value of MysteryClass } } Unfortunately, this did not work and I have no debug messages printed out. Does anyone see what is wrong with my implementation of the PropertyChangeSupport and Listener interfaces? I want to print a debug statement whenever incrementCounter is called or the value of secretCounter changes.

  • Accessing Instance Variables from NSTimer selector

    - by Timbo
    Firstly newbie question: What's the difference between a selector and a method? Secondly newbie question (who would have thought): I need to loop some code based on instance variables and pause between loops until some condition (of course based on instance variables) is met. I've looked at sleep, I've looked at NSThread. In both discussions working through those options many asked why don't I use NSTimer, so here I am. Ok so it's simple enough to get a method (selector? ) to fire on a schedule. Problem I have is that I don't know how to see instance variables I've set up outside the timer from within the code NSTimer fires. I need to see those variables from the NSTimer selector code as I 1) will be updating their values and 2) will set labels based on those values. Here's some code that shows the concept… eventually I'd invalidate the timers based on myVariable too, however I've excluded that for code clarity. MyClass *aMyClassInstance = [MyClass new]; [aMyClassInstance setMyVariable:0]; [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(doStuff) userInfo:nil repeats:YES]; [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(doSomeOtherStuff) userInfo:nil repeats:YES]; - (void) doStuff { [aMyClassInstance setMyVariable:11]; // don't actually have access to set aMyClassInstance.myVariable [self updateSomeUILabel:[NSNumber numberWithInt:aMyClassInstance.myVariable]]; // don't actually have access to aMyClassInstance.myVariable } - (void) doSomeOtherStuff { [aMyClassInstance setMyVariable:22]; // don't actually have access to set aMyClassInstance.myVariable [self updateSomeUILabel:[NSNumber numberWithInt:aMyClassInstance.myVariable]]; // don't actually have access to aMyClassInstance.myVariable } - (void) updateSomeUILabel:(NSNumber *)arg{ int value = [arg intValue]; someUILabel.text = [NSString stringWithFormat:@"myVariable = %d", value]; // Updates the UI with new instance variable values }

  • C Programming - Passing a pointer to array

    - by Pedro
    How do I pass a pointer value to an array of the struct; For example, on a txt I have this: John Doe;[email protected];214425532; My code: typedef struct Person{ char name[100]; char email[100]; int phone; }PERSON; int main(){ PERSON persons[100]; FILE *fp; char *ap_name; char *ap_email; char *ap_phone; char line[100]; fp=("text.txt","r"); if(fp==NULL){ exit(1); } else{ fgets(line,100,fp); ap_name=strtok(line,";"); ap_email=strtok(NULL,";"); ap_phone=strtok(NULL,";"); } return 0; } My question is how can I pass the value of ap_name, ap_email, ap_phone to the struct? And, do I need to use all of these pointers?

  • Asp.net MVC - Model binding image button

    - by big dave
    I've got a very complex form and i'm using the MVC model binding to capture all the information I've got it set up to capture all the different submissions that can happen as there are about 10 different submit buttons on the form, and there are also 2 image buttons I tried to get a bit clever (or so i thought) with capturing the image button submissions, and have created a child class so that i can capture the x value that's returned public class ImageButtonViewData { public int x { get; set; } public string Value { get; set; } } The parent class looks something like this public class ViewDataObject { public ImageButtonViewData ImageButton { get; set; } public ViewDataObject(){ this.ImageButton = new ImageButton(); } } The html for the image button then looks like <input type="image" id="ViewDataObject_ImageButton" name="ViewDataObject.ImageButton" /> This works fine in all browsers except for Chrome. When i debug it in chrome, the Request.Form object contains the values that i would expect, but after the model binding has occurred, the ImageButton property on the ViewDataObject has been set to null The only difference that i can see between the submission values is that Chrome passes the x as lower case (ViewDataObject.ImageButton.x) and IE passes it as upper case (ViewDataObject.ImageButton.X) but i didn't think that model binding took any notice of casing on property names Does anyone have any ideas ?
