  • Can't set element ID in JavaScript, it's always undefined

    - by Dylaan Alith
    Hi, I want to have a function that generates ID's on the fly for a given jquery object, if it doesn't have one already. These ID's should then be used in future requests. I came up with the code below, but it doesn't work. The ID's are never set. The commented out alert statement below always return undefined. I always pass code like $(this) or $(options.el) as a parameter to substitute 'el'. Initially, the elements do not have explicitly ID set in HTML. Any help would be appreciated, here's the code: getElementId: function(el) { if(undefined == el.attr('id')) { el.attr('id',"anim-"+Math.random().toString().substr(2)); } // alert(el.attr('id')); return el.attr('id'); },

  • JavaScript - question regarding data structure

    - by orokusaki
    I'm trying to calculate somebody's bowel health based on a points system. I can edit the data structure, or logic in any way. I'm just trying to write a function and data structure to handle this ability. Pseudo calculator function: // Bowel health calculator var points = 0; If age is from 30 and 34: points += 1 If age is from 35 and 40: points += 2 If daily BMs is from 1 and 3: points -= 1 If daily BMs is from 4 and 6: points -= 2 return points; Pseudo data structure: var points_map = { age: { '30-34': 1, '35-40': 2 }, dbm: { '1-3': -1, '4-6': -2 } }; I have a full spreadsheet of data like this, and I am trying to write a DRY version of code and a DRY version of this data (ie, probably not a string for the '30-34', etc) in order to handle this sort of thing without a humongous number of switch statements.

  • IE is not loading all images

    - by newbie
    I have jQuery code that loads images with jQuery load method. It works perfectly in all other browsers, except in IE. I have about 10 images, but IE only loads few of those images and then stops loading. What could be causing this? $(".image-container").each(function() { ... some code here ... var img = $("img", this); $(img).load(function () { ... some code here ... }); });

  • Jquery Exclude a Selector?

    - by Wes
    I've got a form that I clear on focus. I've selected the whole form and it works great except that the submit button goes blank when I click it. how can I exclude my input of input#submit from the following code? $(".wpcf7-form input, .wpcf7-form textarea").focus(function() { if( this.value == this.defaultValue ) { this.value = ""; $(this).addClass('filled'); } }).blur(function() { if( !this.value.length ) { this.value = this.defaultValue; $(this).removeClass('filled'); } });

  • jQuery doesn't fire some events while I'm not logged in (Joomla)

    - by Andrew Sekaev
    So basically, .resize function fails until I log in. What does that mean? And how that can be fixed? Almost all other functions work fine. The site is still in developement, so no live version sadly. UPDATE: jQuery(window).resize(function() { var windowSize = jQuery(window).width() var windowWidth = (jQuery(window).width()-60)/6; var windowHeight = windowWidth/1.6; /*grid resize*/ jQuery('.xc-block').css({'width':windowWidth, 'height':windowHeight}); }); This is very simple script, cant really tell what can be wrong... Any thoughts guys? P.S:also no errors in FireBug...

  • jQuery UI sortable issue

    - by colourandcode
    When I try to use a sortable event . (For instance the stop() event) It only works when I bind it using : $('.selector').bind('sortstop', function(event, ui) { ... }); rather than $('.selector').sortable({ stop: function(event, ui) { ... } }); Is there a missing piece in this? The only reason I ask is because when I bind using the actual bind() method it's not giving me access to the event or ui parameters I pass in. I'm always returned undefined.

  • How do I use Declarations (type, inline, optimize) in Scheme?

    - by kunjaan
    How do I declare the types of the parameters in order to circumvent type checking? How do I optimize the speed to tell the compiler to run the function as fast as possible like (optimize speed (safety 0))? How do I make an inline function in Scheme? How do I use an unboxed representation of a data object? And finally are any of these important or necessary? Can I depend on my compiler to make these optimizations? thanks, kunjaan.

  • Why is JSON outputting out of order?

    - by dcp3450
    I'm am trying to get a list of weather information for 8 locations. I'm using a weather API that accepts longitude and latitude and spits back json output with the weather info for that location. I feed the coords in order 0-7 but when json processes the data it comes back in a seemingly random order. I assume it's because some process faster than others and json is outputing what it gets back as it gets it. The output is correct, only the order is wrong. var loc = null; var body = ""; var campuses = new Array(8); campuses[0] = "34.47242,-84.42489,1"; campuses[1] = "33.81488,-84.62048,2"; campuses[2] = "34.27502,-84.46976,3"; campuses[3] = "33.92987,-84.55065,4"; campuses[4] = "34.03433,-84.46723,5"; campuses[5] = "34.08362,-84.67115,6"; campuses[6] = "33.91124,-84.82634,7"; campuses[7] = "34.10409,-84.51804,8"; function getWeather(campusArray) { body += '<p class="topTitle">Campus Weather</p>'; var cSplit = new Array(); cSplit = campusArray.split(','); var loc = "http://www.worldweatheronline.com/feed/weather.ashx?q="+cSplit[0]+","+cSplit[1]+"&format=json&num_of_days=2&key=0a05fff921162948110401&callback=?"; $('#content').html('asdf'); $.getJSON(loc,function(js) { var data = js.data; var humidity = data.current_condition[0].humidity; var tempF = data.current_condition[0].temp_F; var iconDESC = data.current_condition[0].weatherDesc[0].value; var iconURL = data.current_condition[0].weatherIconUrl[0].value; var windDir = data.current_condition[0].winddir16Point; var windSpeed = data.current_condition[0].windspeedMiles; var tempMaxF = data.weather[0].tempMaxF; var tempMinF = data.weather[0].tempMinF; body += '<p class="title">'+cSplit[2]+'</p>'+ '<span class="body">'+tempF+ ' '+windSpeed+ '<img src="'+iconURL+'" /></span>'; $('#content').html(body); }); } getWeather(campuses[0]); getWeather(campuses[1]); getWeather(campuses[2]); getWeather(campuses[3]); getWeather(campuses[4]); getWeather(campuses[5]); getWeather(campuses[6]); getWeather(campuses[7]); I have also tried it as $.ajax var loc = null; var body = ""; var campuses = new Array(8); campuses[0] = "34.47242,-84.42489,1"; campuses[1] = "33.81488,-84.62048,2"; campuses[2] = "34.27502,-84.46976,3"; campuses[3] = "33.92987,-84.55065,4"; campuses[4] = "34.03433,-84.46723,5"; campuses[5] = "34.08362,-84.67115,6"; campuses[6] = "33.91124,-84.82634,7"; campuses[7] = "34.10409,-84.51804,8"; function getWeather(campusArray) { body += '<p class="topTitle">Campus Weather</p>'; var cSplit = new Array(); cSplit = campusArray.split(','); var loc = "http://www.worldweatheronline.com/feed/weather.ashx?q="+cSplit[0]+","+cSplit[1]+"&format=json&num_of_days=2&key=0a05fff921162948110401&callback=?"; $.ajax({ url: loc, async: true, dataType: "json", success: function(js) { var data = js.data; var humidity = data.current_condition[0].humidity; var tempF = data.current_condition[0].temp_F; var iconDESC = data.current_condition[0].weatherDesc[0].value; var iconURL = data.current_condition[0].weatherIconUrl[0].value; var windDir = data.current_condition[0].winddir16Point; var windSpeed = data.current_condition[0].windspeedMiles; var tempMaxF = data.weather[0].tempMaxF; var tempMinF = data.weather[0].tempMinF; body += '<p class="title">'+cSplit[2]+'</p>'+ '<span class="body">'+tempF+ ' '+windSpeed+ '<img src="'+iconURL+'" /></span>'; $('#content').html(body); } }); } getWeather(campuses[0]); getWeather(campuses[1]); getWeather(campuses[2]); getWeather(campuses[3]); getWeather(campuses[4]); getWeather(campuses[5]); getWeather(campuses[6]); getWeather(campuses[7]); EDIT: example of json output: { "data": { "current_condition": [ {"cloudcover": "100", "humidity": "93", "observation_time": "04:04 PM", "precipMM": "0.0", "pressure": "1009", "temp_C": "2", "temp_F": "36", "visibility": "8", "weatherCode": "116", "weatherDesc": [ {"value": "Mist" } ], "weatherIconUrl": [ {"value": "http:\/\/www.worldweatheronline.com\/images\/wsymbols01_png_64\/wsymbol_0006_mist.png" } ], "winddir16Point": "WNW", "winddirDegree": "290", "windspeedKmph": "7", "windspeedMiles": "4" } ], "request": [ {"query": "Lat 34.47 and Lon -84.42", "type": "LatLon" } ], "weather": [ {"date": "2011-01-06", "precipMM": "9.3", "tempMaxC": "7", "tempMaxF": "45", "tempMinC": "2", "tempMinF": "35", "weatherCode": "113", "weatherDesc": [ {"value": "Sunny" } ], "weatherIconUrl": [ {"value": "http:\/\/www.worldweatheronline.com\/images\/wsymbols01_png_64\/wsymbol_0001_sunny.png" } ], "winddir16Point": "WNW", "winddirDegree": "293", "winddirection": "WNW", "windspeedKmph": "20", "windspeedMiles": "13" }, {"date": "2011-01-07", "precipMM": "0.0", "tempMaxC": "6", "tempMaxF": "44", "tempMinC": "0", "tempMinF": "31", "weatherCode": "116", "weatherDesc": [ {"value": "Partly Cloudy" } ], "weatherIconUrl": [ {"value": "http:\/\/www.worldweatheronline.com\/images\/wsymbols01_png_64\/wsymbol_0002_sunny_intervals.png" } ], "winddir16Point": "WNW", "winddirDegree": "286", "winddirection": "WNW", "windspeedKmph": "25", "windspeedMiles": "16" } ] }}

  • How do I bind the Overlay Tool for new Ajax elements in Jquery?

    - by Hooman Ahmadi
    Hi, I'm using: echo $javascript->link('tools.overlay-1.0.4', false); which is initialized with: $(".overlay_popup").overlay({ expose: '#000000', close: '.close_overlay', finish: { top: 'center', left: 'center', absolute: false } }); I call the overlay popup box like this: echo $html->link( "add part", array('controller'=>'garage_parts', 'action'=>'addfrompartlist', $gcar['GarageCar']['id'], $gcar['GarageCar']['car_id']), array('class'=>'js-ajax overlay_popup', 'id'=>'add_part_overlay', 'rel'=>'.overlay_container') ); This all works fine and dandy, however I have an ajax function that dynamically adds the "add part" hyperlink button shown above and I have no idea how to bind this new button to the overlay. Normally, I would use something like this: $(".overlay_popup").bind("click", function(){... but this didn't work for the overlay. Any ideas on how I can successfully do this?

  • If free() knows the length of my array, why can't I ask for it in my own code?

    - by Chris Cooper
    I know that it's a common convention to pass the length of dynamically allocated arrays to functions that manipulate them: void initializeAndFree(int* anArray, int length); int main(){ int arrayLength = 0; scanf("%d", &arrayLength); int* myArray = (int*)malloc(sizeof(int)*arrayLength); initializeAndFree(myArray, arrayLength); } void initializeAndFree(int* anArray, int length){ int i = 0; for (i = 0; i < length; i++) { anArray[i] = 0; } free(anArray); } but if there's no way for me to get the length of the allocated memory from a pointer, how does free() "automagically" know what to deallocate? Why can't I get in on the magic, as a C programmer? Where does free() get its free (har-har) knowledge from?

  • How do I post dynamic information to Facebook from Flash?

    - by daidai
    I am building a Flash site and I want to be able to allow the user to post dynamically produced information to their Facebook wall, but I can't find out any information within the Facebook developers documentation. Its simple enough in Javascript/HTML: <script type="text/javascript"> function callPublish(msg, attachment, action_link) { FB.ensureInit(function () { FB.Connect.streamPublish('', attachment, action_link); }); } </script> <input type="button" onclick="callPublish('',{'name':'Post this to Facebook','href':'http://dev2.com','description':'this is some body test'},null);return false;" value="Preview Dialog" /> As you can see I don't want to create sessions or login or anything complicated, just post to info to their wall.

  • Turing's Craft exercise stumped me... seems too easy.

    - by Chris
    "Write a for loop that prints the integers 1 through 40, separated by spaces or new lines. You may use only one variable, count which has already been declared as an integer." So I use... for(count = 1; count <= 40; count++) { cout << " " << count; } but they are using stdio.h as the only header and cout is not recognized. It hints that the output format should be (" ",count), but I can't figure out what print function to use. stdio.h can use fprintf or fwrite, but I don't have enough parameters for either function. Any ideas?

  • jQuery ajax request to php, how to return plain text only

    - by jyoseph
    I am making an ajax request to a php page and I cannot for the life of me get it to just return plain text. $.ajax({ type: 'GET', url: '/shipping/test.php', cache: false, dataType: 'text', data: myData, success: function(data){ console.log(data) } }); in test.php I am including this script to get UPS rates. I am then calling the function with $rate = ups($dest_zip,$service,$weight,$length,$width,$height); I am doing echo $rate; at the bottom of test.php. When viewed in a browser shows the rate, that's great. But when I request the page via ajax I get a bunch of XML. Pastie here: http://pastie.org/1416142 My question is, how do I get it so I can just return the plain text string from the ajax call, where the result data will be a number? Edit, here's what I see in Firebug- Response tab: HTML tab:

  • Pushing notifications to a JavaScript?

    - by Michael Stum
    I'm just wondering if there is a way to have a server push information to a JavaScript function. Essentially I have a Dashboard-type page that has a javaScript function to get updates from the server and update the dashboard. I would like my server to be able to "ping" the JS. I don't even know how that could be possible (I'm guessing Twitter and Facebook use polling?), but I'd thought I ask. I heard of Comet, but I don't know if that works with a plain standard IIS 7 installation? (It's a SharePoint 2010 site if that matters in any way) If I understand it correctly, Comet is essentially a constantly open connection, so it seems like it's actually the opposite of what I want (reducing # of requests and therefore load)

  • Objective-C - Unloading loaded view when it is swapped

    - by teepusink
    Hi, What is the best way to do view management in a multiview application? Right now I have this ViewSwitcher method/function that comes from a custom delegate I created. The code is a whole bunch of if else like this MyViewController *c = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil]; c.delegate = self; self.myViewController = c; [self.viewHolder insertSubview:c.view atIndex:0]; [c release]; That works fine, but when I visited the function a second time, is there going to be 2 instances of MyViewController now or just 1? How do I unload MyViewController when I switch to another view? Or is there a better way to manage my views? Thanks, Tee

  • $.get sends prototype functions in request URL?

    - by pimvdb
    I have some prototype functions added to Object which in my opinion were practical in certain scenarios. However, I noticed that when I executed a $.get, the prototype functions are handled as data members and are sent like http://...?prototypefunc=false. This is rather useless as I don't supply these as data members, but they are added to the query string. To be exact, I have this code: Object.prototype.in = function() { for(var i=0; i<arguments.length; i++) if(arguments[i] == this) return true; return false; } $.get('http://localhost/test.php', {'test': 'foo'}, function(text) { }); The corresponding URL constructed is: http://localhost/test.php?test=foo&in=false How can I avoid this?

  • C++: Template functor cannot deduce reference type

    - by maciekp
    I've got a functor f, which takes a function func and a parameter t of the same type as func. I cannot pass g to f because of compilation error (no matching function for call to f(int&, void (&)(int&)) ). If g would take non-reference parameter g(int s), compilation finishes. Or if I manually specify template parameter f(i, g), compilation also finishes. template<typename T> void f(T t, void (*func)(T)) {} void g(int& s) {} int main(int, char*[]) { int i = 7; f(i, g); // compilation error here return 0; } How can I get deduction to work?
