  • Simple Form validation failing Backbone

    - by Corey Buchillon
    Im not exactly adept at coding so Im probably missing something, but my view here is failing to refuse submission when one or both of the fields are empty. I have a feeling something isnt connected right to my template for the row and the view of the form Form = Backbone.View.extend({ //form vie el: '.item-form', initialize: function(){ }, events: { 'click #additem': 'addModel' }, addModel: function(itemName, price){ // simple validation before adding to collection if (itemName !="" && price !="" ){ var item = new Item({ itemName: this.$("#item").val(), price: this.$("#price").val()}); items.add(item); $("#message").html("Please wait; the task is being added."); item.save(null, {success: function (item, response,options) { item.id= item.attributes._id.$id; item.attributes.id = item.attributes._id.$id; new ItemsView({collection: items}); $("#message").html(""); } }); this.$("#item").val(''); this.$("#price").val(''); } else { alert('Please fill in both fields'); } } }); and HTML <table class="itemTable"> <thead> <tr> <th>Item</th> <th>Price</th> <th></th> </tr> </thead> <tbody class="tableBody"> <script type="text/template" id="table-row"> <td><%= itemName %></td> <td><%= price %></td> <td><button class="complete">Complete</button> <button class="remove">Remove</button></td> </script> </tbody> </table> <form class="item-form"> <input type="text" name="item" id="item" placeholder="Item"/> <!-- goes to itemName in the template for the body --> <input type="text" name="price" id="price" placeholder="Price" /><!--goes to price in the template for the body --> <button type="button" id="additem">Add</button> </form> <div id="message"></div>

  • Lua: Random: Percentage

    - by jargl
    I'm creating a game and currently have to deal with some math.randomness. As I'm not that strong in Lua, how do you think Can you make an algorithm that uses math.random with a given percentage? I mean a function like this: function randomChance( chance ) -- Magic happens here -- Return either 0 or 1 based on the results of math.random end randomChance( 50 ) -- Like a 50-50 chance of "winning", should result in something like math.random( 1, 2 ) == 1 (?) randomChance(20) -- 20% chance to result in a 1 randomChance(0) -- Result always is 0 However I have no clue how to go on, and I completely suck at algorithms I hope you understood my bad explanation of what I'm trying to accomplish

  • iPhone NSMutableDictionary setObject forKey after initWithContentsOfFile

    - by andrew
    so here's my function + (void) AddAddress:(NSString*)ip:(NSString*)mac { NSMutableDictionary* currentAddresses = [[NSMutableDictionary alloc] initWithContentsOfFile:[self filePath:ADDRESSES_FILE]]; [currentAddresses setObject:mac forKey:ip]; [Configuration Write:currentAddresses]; [currentAddresses release]; } [self filePath:ADDRESSES_FILE] returns a string containing the full path of a file (ADDRESSES_FILE) located in the Documents. The file may not exist, in this case I want to just write an object to the dictionary and then write it down the problem is that when i do setObject forKey it doesn't add anything to the dict (if i just do alloc init to the dict, it works fine, but i want to read the records from the file, if there are any, and replace/add a record by using the AddAddress function)

  • Passing variable string to create arrays (Android)

    - by dweebsonduty
    Hello all, I am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type") But if I try something like getResources().getStringArray(R.array.thelist); it doesn't work. Can someone point me in the right direction? public void list_it(String thelist){ String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types); setListAdapter(mAdapter); ListView lv = getListView(); lv.setTextFilterEnabled(true); }

  • Extracting text from PDF with Poppler (C++)

    - by nico
    I'm trying to get my way through Poppler and its (lack of) documentation. What I want to do is a very simple thing: open a PDF file and read the text in it. I'm then going to process the text, but that doesn't really matter here. So... I saw the poppler_page_get_text function, and it kind of works, but I have to specify a selection rectangle, which is not very handy. Isn't there just a very simple function that would output the PDF text in order (maybe line by line?). Thank you Nicola

  • Why does my regex fail when the number ends in 0?

    - by Russell C.
    This is a really basic regex question but since I can't seem to figure out why the match is failing in certain circumstances I figured I'd post it to see if anyone else can point out what I'm missing. I'm trying to pull out the 2 sets of digits from strings of the form: 12309123098_102938120938120938 1321312_103810312032123 123123123_10983094854905490 38293827_1293120938129308 I'm using the following code to process each string: if($string && $string =~ /^(\d)+_(\d)+$/) { if(IsInteger($1) && IsInteger($2)) { print "success ('$1','$2')"; } else { print "fail"; } } Where the IsInterger() function is as follows: sub IsInteger { my $integer = shift; if($integer && $integer =~ /^\d+$/) { return 1; } return; } This function seems to work most of the time but fails on the following for some reason: 1287123437_1268098784380 1287123437_1267589971660 Any ideas on why these fail while others succeed? Thanks in advance for your help!

  • Haskell - mapping the odd placed values and the even placed values differently

    - by Abstract
    Hey guys, is there an easy way. To take a list of numbers, say 123456. Then multiply the odd placed by three and the even placed by 1. i.e. (1 * 3) + (2 * 1) + (3 * 3) + (4*1) + (5*3) + (6*1) i was thinking the map function somewhere along the lines. But i don't know how to map *3 to just the odd placed values. Oh and if you could give me the version not in prelude that would be great like the actual function or functions, as if its being imported from an external haskell file Thanks for the help

  • Switching layouts page jumping (improvement to script)

    - by Ricardo Zea
    Hello, I'm using this script to switch layouts in a page: $("span.switcher").click(function () { $("span.switcher").toggleClass("swap"); /*!*/ $("ol.search-results").fadeOut("fast", function() { $(this).fadeIn("fast").toggleClass("grid"); }); The script works fine, the problem I have is that if the switch view is down the page, the layout changes and then the page jumps back up. If I add 'return false' right where you see the /* ! */ in the second line the script doesn't work. Also, as you can see, I'm using < span instead of < a since I was told that using other element other than < a would stop the page from jumping. Any idea how to fix the jumping of the page? Thanks.

  • Emacs with CEDET changes copy/paste to include trailing spaces?

    - by Paul D.
    I just started trying out CEDET today, which I really like, but it seems to do something completely worthless with respect to copying/pasting. If I highlight some stuff and copy it, when it gets pasted back the newlines are eliminated and there is just a ton of trailing whitespace on each line. This is really worthless. All I have in my .emacs right now for CEDET is the following: (load-file "~/.emacs.d/cedet-1.0pre7/common/cedet.el") (require 'semantic-ia) (require 'semantic-gcc) (semantic-load-enable-code-helpers) Does anybody know how to turn this off? I can't find anything about this except that the CEDET main page says it has "magic copy & paste".

  • How to convert jquery collection to xml string for an ajax request

    - by Jim
    I created a jquery collection that stores xml as follows: var rh_request = $('') .attr('user_id', user_id) .attr('company_id', company_id) .attr('action', 'x'); I want to post it to my server via an ajax request as follows: $.ajax({ type: "POST", url: mywebsiteURL, processData: false, dataType: "xml", data: rh_request.html(), success: mycallbackfunction }); My problem is that the "data" parameter of the ajax call needs a string version of the xml and it seems neither Jquery's .html() or .text() function yields this. I have older code that used straight javascript to form the outgoing xml and calling the DOM .xml() function yielded a string that worked. How is this done with a jquery collection???

  • Using two xmlhttprequest calls on a page

    - by blacktooth
    I have two divisions, <div id=statuslist></div><div id=customerlist></div> The function sendReq() creates a xmlhttprequest and fetches the data into the division. sendReq('statuslist','./include/util.php?do=getstatuslist','NULL'); sendReq('customerlist','emphome.php?do=getcustomerlist','NULL'); I have a problem, The data fetched into the 'customerlist' gets copied onto 'statuslist' If i change the order of function calls, sendReq('customerlist','emphome.php?do=getcustomerlist','NULL'); sendReq('statuslist','./include/util.php?do=getstatuslist','NULL'); Now the data of 'statuslist' gets into 'customerlist'.. Whats the problem with the code?

  • Shortest distance between two line segments

    - by Frank
    I need a function to find the shortest distance between two line segments. A line segment is defined by two endpoints. So for example one of my line segments (AB) would be defined by the two points A (x1,y1) and B (x2,y2) and the other (CD) would be defined by the two points C (x1,y1) and D (x2,y2). Feel free to write the solution in any language you want and I can translate it into javascript. Please keep in mind my geometry skills are pretty rusty. I have already seen http://stochastix.wordpress.com/2008/12/28/distance-between-two-lines/ and I am not sure how to translate this into a function. Thank you so much for help.

  • 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?

Also I'd like to check the server response and perform some actions if the right conditions meet , but I ' m unsure of how and when the server send back the response .

  • Correct handling of return data

    - by Serhiy
    Hello, I have a question related to correct handling of returns of the DAO library I'm writing for one project. This library probably is going to be used by another people and I want to do it correctly. So I would like to know, how I should deal with return statements of the functions of my DAO. Example 1 I have function to getCustomer which should return String. In case query doesn't return any result should I return null, empty string or throw some kind of Exception? Example 2 I have function getCutomerList which return ArrayList. In case query doesn't return any result should I return null, empty ArrayList or throw some Exception? Example 3 Some sql exception was detected, what should I do: throw exception or do try..catch of the block where it can occur? What is the "good" practice or "best" practice to apply in my case? Thanks on advance, Serhiy.

  • 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" } ] }}

  • Use deployJava.js to check for/automatically install latest JRE version for web applet

    - by Pryo
    I'd like to use the deployJava.js tool to have Java automatically detect the currently installed JRE and install an updated version if necessary. My initial impression when reading about deployJava.js was that it would do this out of the box when you simply set a version number as a function parameter for the "runApplet" function. But this has never seemed to work. Is it even possible to do this, and if so, how? Here is my current code for launching my applet: <script type="text/javascript" src="https://www.java.com/js/deployJava.js"></script> <script type="text/javascript"> var attributes = {id:"applet", name:"TheApplet", code:"TheApplet"}; var parameters = {jnlp_href: "http://localhost/TheApplet.jnlp"}; deployJava.runApplet(attributes, parameters, "1.6.0_31"); </script> Thanks
