Scenario: I have a REST API and when i call it, it returns back response in JSON format. Need to To: Create a HTML page and use javascript to call that REST API and capture JSON response and print in the same HTML page. <script type="text/javascript"> function loadMe() { loadJSON('http://myrestAPI'); } function loadJSON(url) { //Help me here to capture the response and print in html page. } </script> I would appreciate your help.

  • iPhone app getting XML then refreshing it at intervals...

    - by user157733
    I have an app which gets some data from the web via an XML document. I have this working fine and have followed apples SeismicXML example (uses NSURLRequest etc). I am very new to this so I have to admit that I do not totally understand all the code that gets the XML - but it is working. My problem is that my app may be running for some time so I want to be able to refresh the XML every now and again and check to see if it is different. If it is different I need to update my contents. Basically this means my questions are.... Is there a standard way of doing this? I was thinking of creating a timer to call the function which parses the XML but I can't figure out which function to call. If anyone can give me any pointers or even better examples of this it would be fab. Thanks

  • PHP OOP: Parenting objects/functions?

    - by Industrial
    Hi everyone, How is parenting functions in PHP done properly according to the following example? Can I make sure that my array isn't overwritten and the previous values inside array lost, on each addArray call? function arraybase() { $this->array = new ArrayObject(); return $this; } function addArray($value) { parent::$this->arraybase(); $this->array->append($value); return $this; } $this->addArray('1')->addArray('2')->addArray('3'); // outputs: Array ( [0] => 3 ) Thanks a lot!

  • Defautlt Contoller in CodeIgniter

    - by gregavola
    Hello everyone, I am wondering if there is any other configuration options for a default controller. For example - if I have a controller called "site" and I set the default controller in the following file: application/config/routes.php to: $route['default_controller'] = "site"; I should be able to go to http://localhost and that brings up the index(); function in the site controller. However, if I try to do go to http://localhost/index.php/index2 to load the index2(); function I get a 404 error. If i change the URL to http://localhost/index.php/site/index2 it works fine - but I thought already set the default controller. Is there any way around this? Any thoughts?

  • jQuery .load(), don't show new content until images loaded

    - by Jarred
    Hi. I have been working on a jQuery photo slideshow. It scales the images to the browser size, and slides them left and right. There is no pre-determined size or aspect ratio, the script does everything on the fly. It requires that all images be fully loaded, so it can custom resize each individual image based on it's own aspect ratio ( width():height(), etc ), calculate the width of containing div, and calculate the slide distance from one image to another. As a stand-alone, it works pretty well (despite my lack of skills)! I simply hide the slideshow containing div at (document).ready, allow the images to load, then run the slideshow prep scripts at (window).load. Once this is done, it only then makes the slideshow divs, images, etc appear, properly sized, positioned and ready to roll. The ultimate goal is to be able to load in any number of slideshows without refreshing the page. The point of this is to be able to play uninterrupted background music. I know music on websites is annoying, but the target market likes it, a lot! I am using (target).load(page.php .element, function prepInsertNewShow() { //Prepare slideshow resizeImages(); slideArray(); //Show slideshow (target).fadeIn(); }); and it definitely works! The problem is that I cannot find a way to hold off on preparing and showing the new content until the images have finished loading. It is running the slideshow prep scripts (which are totally dependent on the images being fully loaded), before the images are loaded. This results in a completely jacked up show! What I want to do is this - (target).load(page.php .element, function prepInsertNewShow() { //Wait until images are loaded $('img').load( function() { //Prepare slideshow resizeImages(); slideArray(); //Show slideshow (target).fadeIn(); } }); But this doesn't seem to work, the new content is never shown. You can see a live version here. The initial gallery loads correctly, everything looks good. The only nav link that works is Galleries Engagement, which will load a new show (a containing div with multiple <img> tags). You will see that the images are not centered, the containing div and slide distances are much too small, as they were calculated using images that were not actually loaded. Is there any way I can delay handling and showing new content until it is fully loaded? Any suggestions would be most appreciated, thanks for your time! PS - It just occurred to me while typing this that a decent solution may be to insert "width=x" height="x" into the <img> tags, so the script can work from those values, even if the images have not loaded...hmm...

  • get js file query param from inside it

    - by vsync
    I load this file with some query param like this: src='somefile.js?userId=123' I wrote the below function in 'somefile.js' file that reads the 'userId' query param but I feel this is not the best approach. Frankly, its quite ugly. Is there a better way? function getId(){ var scripts = document.getElementsByTagName('script'), script; for(var i in scripts){ if( scripts.hasOwnProperty(i) && scripts[i].src.indexOf('somefile.js') != -1 ) var script = scripts[i]; } var s = (script.getAttribute.length !== undefined) ? script.getAttribute('src') : script.getAttribute('src', 2); return getQueryParams('userId',s); };

  • jQuery - Programmatically Trigger Event

    - by Sonny
    I need to programmatically trigger a click event that's being handled by jQuery. Here's the current code: var $thumbs = $('#PhotoGalleryThumbs .tile'); var $zoom = $('#PhotoGallery #PhotoGalleryZoom img'); var $description = $('#PhotoGallery #PhotoGalleryDescription'); $thumbs.click(function(event) { event.preventDefault(); var $thumb = $(this); $thumb.addClass('selected') .siblings().removeClass('selected'); $zoom.attr('src', $thumb.children('a').attr('href')); $description.html($thumb.find('img').attr('alt')); }); I am having a mental block working out how to create a function out of the event handling code and then arbitrarily calling it for an element in the $thumbs object.

  • Get next key-value pair in an object

    - by captainclam
    So, given a key, I want to find the next property in an object. Then, I want to return the value of the NEXT property. I can not rely on the keys to be ordered or sequential (they're uuids). Please see below for trivial example of what I want: var db ={ a: 1, b: 2, c: 3 } var next = function(db, key) { // ??? } next(db, 'a'); // I want 2 next(db, 'b'); // I want 3 I also want a prev() function, but I'm sure it will be the same solution. This seems like such a trivial problem but I can't for the life of me figure out how to do it. Happy for the solution to use underscore.js or be written in coffeescript :)

  • overriding callbacks avoiding attribute pollution

    - by pygabriel
    I've a class that has some callbacks and its own interface, something like: class Service: def __init__(self): connect("service_resolved", self.service_resolved) def service_resolved(self, a,b c): ''' This function is called when it's triggered service resolved signal and has a lot of parameters''' the connect function is for example the gtkwidget.connect, but I want that this connection is something more general, so I've decided to use a "twisted like" approach: class MyService(Service): def my_on_service_resolved(self, little_param): ''' it's a decorated version of srvice_resolved ''' def service_resolved(self,a,b,c): super(MyService,self).service_resolved(a,b,c) little_param = "something that's obtained from a,b,c" self.my_on_service_resolved(little_param) So I can use MyService by overriding my_on_service_resolved. The problem is the "attributes" pollution. In the real implementation, Service has some attributes that can accidentally be overriden in MyService and those who subclass MyService. How can I avoid attribute pollution? What I've thought is a "wrapper" like approach but I don't know if it's a good solution: class WrapperService(): def __init__(self): self._service = service_resolved # how to override self._service.service_resolved callback? def my_on_service_resolved(self,param): ''' '''

    - by mpet
    I'm trying to make simple five star rating system using Twitter Bootstrap 3 i jQuery. For now, I'm trying to set .hover() and .mouseout() events using counter by writing this code that doesn't work: var i; for (i = 1; i <= 5; i++) { $('#overall_rating_' + i).hover(function(){ $('#overall_rating_' + i).removeClass("glyphicon-star-empty").addClass("glyphicon-star"); }); $('#overall_rating_' + i).mouseout(function(){ $('#overall_rating_' + i).removeClass("glyphicon-star").addClass("glyphicon-star-empty"); }); } Trying to highlight current and previous stars on mouseover. The code is not complete, it would be accompanied by additional sub-counters, but this part doesn't work for now. Any better methods are welcome. What's broken here?

  • Timeout not working in SQL Connection

    - by carlos
    I have this simple code to test that a DB is ready: Function testlocalcon() As Boolean Dim constr As String = _clconstr Try Using t As New SqlConnection() constr = constr & " ; Connect Timeout=1" If Not t.State = Data.ConnectionState.Open Then t.ConnectionString = constr t.Open() If t.State = Data.ConnectionState.Open Then Return True Else Return False End If Else Return True End If End Using Catch ex As Exception Return False End Try End Function I do not want to execute a query, just to check the connection, but no matter what the time out parameter is ignored. I search here (Stackoverflow) and internet and found nothing in how to fix this. Any one else have this problem? Or, are there any other ideas on how to let the application know that the DB is ready?

  • php - How do I get rid of this strange "empty delimiter" message

    - by Steven
    I have some code that uses the stristr function to extract data I need. It works, in that it gives me the results I'm looking for. BUT (you knew there was a but), it gives me this error message for every iteration of the loop: Warning: stristr() [function.stristr]: Empty delimiter in ... line 55 Like I said, the code works apart from this error. Can anyone suggest how i could amend this code to get rid of the message? Thanks in advance $data = stristr("$text", "$key"); $result = string_limit_words($data,2); print "$result<BR>";

  • Prevent Excel from evaluating unneeded expressions in OR()

    - by Wesley
    IF(OR(ISNA(MATCH(8,B10:B17,0)),MATCH(8,B10:B17,0)>8),"",...BLAH...) I understand how to fix this problem by rearranging my formula. I have it the way it is to show this point. You can see the OR() statement checks to see if the first MATCH() returns NA. When it does, OR() should automatically return TRUE and not evaluate the second MATCH() because conditions have been met for the OR() to return true no matter what other arguments there are. You'll notice that the first and second MATCH() functions do the same thing. What's happening is the entire function is returning NA because the second MATCH() is executing even though it doesn't have to, the OR() has been satisfied with one TRUE, therefore the function should return "". Is this a bug or is this intentional?

    I have followed the code example here toupper c++ example And implemented it in my own code as follows void CharString::MakeUpper() { char* str[strlen(m_pString)]; int i=0; str[strlen(m_pString)]=m_pString; char* c; while (str[i]) { c=str[i]; putchar (toupper(c)); i++; } } But this gives me the following compiler error CharString.cpp: In member function 'void CharString::MakeUpper()': CharString.cpp:276: error: invalid conversion from 'char*' to 'int' CharString.cpp:276: error: initializing argument 1of 'int toupper(int)' CharString.cpp: In member function 'void CharString::MakeLower()': This is line 276 putchar (toupper(c)); I understand that toupper is looking for int as a parameter and returns an int also, is that the problem? If so how does the example work?

  • Why is this js code so slow?

    - by SpiderPig
    This code takes 3 seconds on Chrome and 6s on Firefox. If I write the code in Java and run it under Java 7.0 it takes only 10ms. Chrome's JS engine is usually very fast. Why is it so slow here? btw. this code is just for testing. I know it's not very practical way to write a fibonacci function fib = function(n) { if (n < 2) { return n; } else { return fib(n - 1) + fib(n - 2); } }; console.log(fib(32));
