  • jquery.ajax multiple data problem

    - by Guillaume P
    Hi, I've been trying to make this code work for the last 3 hours. I've tried about everytinh, but I'm still unable to get it to work. I only managed to send 1 data. When I use this code, I only manage to retrieve recaptcha_challenge_field. If I remove recaptcha_challenge_field, I retrieve recaptcha_response_field. However, I am unable to retrieve the two at the same time. challengeField = $("#recaptcha_challenge_field").val(); responseField = $("#recaptcha_response_field").val(); var html = $.ajax( { global: false, type: "POST", async: false, dataType: "html", data: "recaptcha_response_field=" + responseField + "&recaptcha_challenge_field=" + challengeField, url: "../ajax.recaptcha.php" }).responseText; if(html == "success") { $("#captchaStatus").html("Success. Submitting form."); return true; } else { $("#captchaStatus").html("Your captcha is incorrect. Please try again"); Recaptcha.reload(); return false; }

  • Retrieve Table Row Index of Current Row

    - by Jon
    Hi Everyone, I am trying to validate a text input when it loses focus. I would like to know which row of the table it is in. This is what I have so far and it keeps coming back as undefined. Any ideas? $("div#step-2 fieldset table tbody tr td input").blur(function() { var tableRow = $(this).parent().parent(); if ($.trim($(this).val()) == "") { $(this).addClass("invalid"); alert(tableRow.rowIndex); $(this).val(""); } else { $(this).removeClass("invalid"); checkTextChanges(); } });

  • Table-level diff and sync procedure for T-SQL

    - by Ville Koskinen
    I'm interested in T-SQL source code for synchronizing a table (or perhaps a subset of it) with data from another similar table. The two tables could contain any variables, for example I could have base table source table ========== ============ id val id val ---------- ------------ 0 1 0 3 1 2 1 2 2 3 3 4 or base table source table =================== ================== key val1 val2 key val1 val2 ------------------- ------------------ A 1 0 A 1 1 B 2 1 C 2 2 C 3 3 E 4 0 or any two tables containing similar columns with similar names. I'd like to be able to check that the two tables have matching columns: the source table has exactly the same columns as the base table and the datatypes match make a diff from the base table to the source table do the necessary updates, deletes and inserts to change the data in the base table to correspond the source table optionally limit the diff to a subset of the base table, preferrably with a stored procedure. Has anyone written a stored proc for this or could you point to a source?

  • ANDing javascript objects together

    - by Jonas
    I ran across this chunk of code (modified) in our application, and am confused to how it works: function someObject() { this.someProperty = {}; this.foo = { bar: { baz: function() { return "Huh?" } } }; this.getValue = function() { return (this.someProperty && this.foo.bar && this.foo.bar.baz && this.foo.bar.baz()) || null; } } function test() { var o = new someObject(); var val = o.getValue(); alert(val); } when you call the test() function, the text "Huh?" is alerted. I'm not sure how the result of getValue is returning that, I would've thought doing A && B && C && D would have returned true, rather than the value of D.

  • jQuery Ajax posting Arrays instead of simple data

    - by Ignacio
    Hey, I've tried to update jQuery to its latest version on a system I'm working and I'm having this issue: I have a file that posts data to a .php: $.post( 'ajax_Save.php', { id: [$('#service_id').val()], number: [$('#number').val()] }, function(data){ ... }); On ajax_Save.php var_dump($_POST) gives: array(26) { ["id"]=> array(1) { [0]=> string(5) "18204" } ["number"]=> array(1) { [0]=> string(5) "18250" }... With jQuery version 1.2.2 the result is: array(26) { ["id"]=> string(5) "18204" ["order_number"]=> string(5) "18250" Which is OK. Any clues? Thx

  • jquery performing calculation on dynamically generated elements

    - by user306472
    I have a table made up of a row of 3 input elements: Price, Quanity, and Total. Under that, I have two links I can click to dynamically generate another row in the table. All that is working well, but actually calculating a value for the total element is giving me trouble. I know how to calculate the value of the first total element but I'm having trouble extending this functionality when I add a new row to the table. Here's the html: <table id="table" border="0"> <thead> <th>Price</th><th>Quantity</th><th>Total</th> </thead> <tbody> <tr> <td><input id ="price" type = "text"></input></td> <td><input id ="quantity" type = "text"></input></td> <td><input id ="total" type = "text"></input></td> </tr> </tbody> </table> <a href="#" id="add">Add New</a> <a href="#" id="remove">Remove</a> Here's the jquery I'm using: $(function(){ $('a#add').click(function(){ $('#table > tbody').append('<tr><td><input id ="price" type = "text"></input></td><td><input id ="quantity" type = "text"></input></td><td><input id ="total" type = "text"></input></td></tr>'); }); $('a#remove').click(function(){ $('#table > tbody > tr:last').remove(); }); }); $(function(){ $('a#calc').click(function(){ var q = $('input#quantity').val(); var p = $('input#price').val(); var tot = (q*p); $('input#total').val(tot); }); }); I'm new to jquery so there's probably a simple method I don't know about that selects the relevant fields I want to calculate. Any guidance would be greatly appreciated.

  • Scala wont pattern match with java.lang.String and Case Class

    - by Stefan
    Hello fellow Scala Programmers I have been working with Scala for some month now, however I have a problem with some properly basic stuff, I am hoping you will help my out with it. case class PersonClass(name: String, age: Int) object CaseTester { def main(args:Array[String]) { val string = "hej" string match { case e:String => println(string) case PersonClass => println(string) } } } When I am doing like this I get error: pattern type is incompatible with expected type; found : object PersonClass required: java.lang.String case PersonClass = println(string) And if I then change the second line in the pattern matching to the following: case e:PersonClass => println(string) I then get the error: error: scrutinee is incompatible with pattern type; found : PersonClass required: java.lang.String case e:PersonClass = println(string) However if I change the string definition to the following it compiles fine in both cases. val string:AnyRef = "hej"

  • ToolTip for a User Control Issue

    - by Gaddigesh
    I have a control inherited from usercontrol, I have implemented it such a way that it acts as XY Plane and displays curves. When user clicks and holds the mouse down for 1 sec i trigger SetToolTip to display tooltip indicationg (x,y) coordinates. Tooltip remains even on drag updating x,y positions System.Windows.Forms.ToolTip myToolTip = new System.Windows.Forms.ToolTip(); myToolTip.SetToolTip(myControl,"x= val,y=val"); It is working fine But Tooltip stops showing after (1)I play around for sometime(click,drag repeatedly) and will never show up (2)I move some other window on this control(this happens sporadically) what could be the problem???

  • javascript ajax variable question..

    - by Kelso
    Hey there, new to AJAX, JS.. Im trying to add to a Javascript/Ajax search script that I've put together. Previously, it had a single search field, called search_word, I added one called search_date. $(".search_button").click(function() { var search_word = $("#search_box").val(); var search_date = $("#datepicker").val(); var dataString = 'search_word='+ search_word; if(search_word=='') { } else { $.ajax({ type: "GET", url: "searchdata.php", data: dataString, In the Ajax, it appears to pass data of dataString, to my processing script. How do I add search date to the dataString so that I can use that var in my searchdata.php? In searchdata, I can do this $search_word=$_GET['search_word']; and use that var, but so far every time i attempt to alter the dataString, it breaks all the other functionality. Thanks!

  • jQuery $.post with PasteBin API

    - by John K
    Ok, I'm trying to use jQuery $.post with the PasteBin API to create a PasteBin page and grab the URL (which the API says it returns). Here is my code so far: $('#send_code').click(function(){ $.post('http://pastebin.com/api_public.php', { paste_name: $('#paste_name').val(), paste_code: $('#paste_code').val() }, function(data){ alert(data); }); } The above script creates the page just fine (I can find them on PasteBin). However, all that is returned is an empty string. I've tried using this same API with php and cURL, and I'm able to retrieve the URL just fine. Can anyone see if I'm doing something wrong? Thanks!

  • Global variables in jQuery

    - by Thorpe Obazee
    I have been working on this script: <script type="text/javascript" src="/js/jquery.js"></script> <script type="text/javascript"> $(function(){ compentecy = $('#competency_id'); $('#add_competency').bind('click', function(e){ e.preventDefault(); $.post('/script.php', {competency_id: compentecy.val(), syllabus_id: 2}, function(){ // competency = $('#competency_id'); competency.children('option[value=' + compentecy.val() + ']').remove(); }); }); }); </script> in the $.post callback function, it seems that I can't access global variables. I tried $.competency but it didn't work. I always get a "competency is undefined" error. I had to reinitialize the variable once again inside the callback. Is there a way to NOT reinitialize the variable inside the callback?

  • Scala type system : basic type mismatch

    - by SiM
    I have a basic type system type mismatch problem: I have a class with a method def Create(nodeItem : NodeItem) = {p_nodeStart.addEndNode(nodeItem)} where p_nodeStart is NodeCache class NodeCache[END_T<:BaseNode] private(node: Node) extends BaseNode { def addEndNode(endNode : END_T) = {this.CACHE_HAS_ENDNODES.Create(endNode)} and the error its giving me is: error: type mismatch; found : nodes.NodeItem required: Nothing def Create(nodeItem : NodeItem) = {p_nodeStart.addEndNode(nodeItem)} while the NodeCache is defined as object NodeTrigger { def Create() { val nodeTimeCache = NodeCache.Create[NodeItem](node) and in object NodeCache object NodeCache { def Create[END_T<:BaseNode]() { val nodeCache = new NodeCache[END_T](node); Any ideas, how to fix the error?

  • C# Memoization of functions with arbitrary number of arguments

    - by Lirik
    I'm trying to create a memoization interface for functions with arbitrary number of arguments, but I'm failing miserably. The first thing I tried is to define an interface for a function which gets memoized automatically upon execution: class EMAFunction:IFunction { Dictionary<List<object>, List<object>> map; class EMAComparer : IEqualityComparer<List<object>> { private int _multiplier = 97; public bool Equals(List<object> a, List<object> b) { List<object> aVals = (List<object>)a[0]; int aPeriod = (int)a[1]; List<object> bVals = (List<object>)b[0]; int bPeriod = (int)b[1]; return (aVals.Count == bVals.Count) && (aPeriod == bPeriod); } public int GetHashCode(List<object> obj) { // Don't compute hash code on null object. if (obj == null) { return 0; } // Get length. int length = obj.Count; List<object> vals = (List<object>) obj[0]; int period = (int) obj[1]; return (_multiplier * vals.GetHashCode() * period.GetHashCode()) + length;; } } public EMAFunction() { NumParams = 2; Name = "EMA"; map = new Dictionary<List<object>, List<object>>(new EMAComparer()); } #region IFunction Members public int NumParams { get; set; } public string Name { get; set; } public object Execute(List<object> parameters) { if (parameters.Count != NumParams) throw new ArgumentException("The num params doesn't match!"); if (!map.ContainsKey(parameters)) { //map.Add(parameters, List<double> values = new List<double>(); List<object> asObj = (List<object>)parameters[0]; foreach (object val in asObj) { values.Add((double)val); } int period = (int)parameters[1]; asObj.Clear(); List<double> ema = TechFunctions.ExponentialMovingAverage(values, period); foreach (double val in ema) { asObj.Add(val); } map.Add(parameters, asObj); } return map[parameters]; } public void ClearMap() { map.Clear(); } #endregion } Here are my tests of the function: private void MemoizeTest() { DataSet dataSet = DataLoader.LoadData(DataLoader.DataSource.FROM_WEB, 1024); List<String> labels = dataSet.DataLabels; Stopwatch sw = new Stopwatch(); IFunction emaFunc = new EMAFunction(); List<object> parameters = new List<object>(); int numRuns = 1000; long sumTicks = 0; parameters.Add(dataSet.GetValues("open")); parameters.Add(12); // First call for(int i = 0; i < numRuns; ++i) { emaFunc.ClearMap();// remove any memoization mappings sw.Start(); emaFunc.Execute(parameters); sw.Stop(); sumTicks += sw.ElapsedTicks; } Console.WriteLine("Average ticks not-memoized " + (sumTicks/numRuns)); sumTicks = 0; // Repeat call for (int i = 0; i < numRuns; ++i) { sw.Start(); emaFunc.Execute(parameters); sw.Stop(); sumTicks += sw.ElapsedTicks; } Console.WriteLine("Average ticks memoized " + (sumTicks/numRuns)); } The performance is confusing me... I expected the memoized function to be faster, but it didn't work out that way: Average ticks not-memoized 106,182 Average ticks memoized 198,854 I tried doubling the data instances to 2048, but the results were about the same: Average ticks not-memoized 232,579 Average ticks memoized 446,280 I did notice that it was correctly finding the parameters in the map and it going directly to the map, but the performance was still slow... I'm either open for troubleshooting help with this example, or if you have a better solution to the problem then please let me know what it is.

  • What are pointers to class members used for?

    - by srikfreak
    I have read about pointers to class members, but I have never seen them being used in any practical applications. Can someone explain what are the use cases of such pointers? Is it really necessary to have such pointers? Eg. class abc { public: int a; abc(int val) { a = val; } }; int main { int abc::*data; abc obj(5); data = &abc::a; cout << "Value of a is " << obj.*data << endl; return 0; } In the above eg. why is the value of 'a' accessed in this manner? What is the advantage of using pointers to class members?

  • Javascript how many characters replaced in a regex?

    - by macca1
    I am sanitizing an input field and manually getting and setting the caret position in the process. With some abstraction, here's the basic idea: <input type="text" onkeyup"check(this)"> And javascript... function check(element) { var charPosition = getCaretPosition(element); $(element).val( sanitize( $(element).val() ) ); setCaretPosition(element, charPosition); } function sanitize(s) { return s.replace(/[^a-zA-Z0-9\s]/g, ''); } This is working fine except when a character does actually get sanitized, my caret position is off by one. Basically I'd like a way to see if the sanitize function has actually replaced a character (and at what index) so then I can adjust the charPosition if necessary. Any ideas?

  • Copying part of a string in C

    - by wolfPack88
    This seems like it should be really simple, but for some reason, I'm not getting it to work. I have a string called seq, which looks like this: ala ile val I want to take the first 3 characters and copy them into a different string. I use the command: memcpy(fileName, seq, 3 * sizeof(char)); That should make fileName = "ala", right? But for some reason, I get fileName = "ala9". I'm currently working around it by just saying fileName[4] = '\0', but was wondering why I'm getting that 9. Note: After changing seq to ala ile val ser and rerunning the same code, fileName becomes "alaK". Not 9 anymore, but still an erroneous character.

  • Want to bind an input field to a jquery-ui slider handle

    - by BFTrick
    hello, I want to bind an input field to the jquery-ui slider handle. So whenever one value changes I want the other value to also change. Ex: if someone types 1000 into the minimum value input field I want the lower slider handle to move to the 1000 mark. Also if the user drags the lower slider handle to 1000 the input field should reflect that. Making the slider reflect the changes in the input field is easy: $(minYearInput).blur(function () { $("#yearSlider").slider("values", 0, parseInt($(this).val())); }); $(maxYearInput).blur(function () { $("#yearSlider").slider("values", 1, parseInt($(this).val())); }); I just need help making the text fields mimic the slider. $("#yearSlider").slider({ range: true, min: 1994, max: 2011, step: 1, values: [ 1994 , 2011 ], slide: function(event, ui) { //what goes here? } }); Any ideas?

Can anyone see what i am doing wrong here?

  • Using type aliases to Java enums

    - by oxbow_lakes
    I would like to achieve something similar to how scala defines Map as both a predefined type and object. In Predef: type Map[A, +B] = collection.immutable.Map[A, B] val Map = collection.immutable.Map //object Map However, I'd like to do this using Java enums (from a shared library). So for example, I'd have some global alias: type Country = my.bespoke.enum.Country val Country = my.bespok.enum.Country //compile error: "object Country is not a value" The reason for this is that I'd like to be able to use code like: if (city.getCountry == Country.UNITED_KINGDOM) //or... if (city.getCountry == UNITED_KINGDOM) Howver, this not possible whilst importing my type alias at the same time. Note: this code would work just fine if I had not declared a predefined type and imported it! Is there some syntax I can use here to achieve this?

  • jQuery validation plugin doesn't work for me

Is there a way how to write it, that the method from outside calling, there's no paramter, but in inside, there's a parameter - for recursion...? The compiler complains that the parameter is not defined when called from outside
