  • jQuery is only returning first item

    - by Andy
    For some strange reason, whenever I have a selector and expect to get multiple items, jQuery is only returning the first item, instead of the entire collection. This is the HTML I have: <a id="reply-424880" class="reply" href="#" rel="nofollow">Reply</a> <a id="reply-424885" class="reply" href="#" rel="nofollow">Reply</a> And the selector: $('.reply').unbind('click').click(function(event) { ... } I have tried debugging using FireBug, and still get the same results. Using the work around I can get it to work: $('a').each(function (index, element) { if ($(element).attr('class') == 'reply') { $(this).unbind('click').click(function(event) { ... }); } }); I would like to use the built-in functionality instead of my work around. Any idea why only the first element would be returned?

  • Javascript: Inherit method from base class and return the subclass's private variable

    - by marisbest2
    I have the following BaseClass defined: function BaseClass (arg1,arg2,arg3) { //constructor code here then - var privateVar = 7500; this.getPrivateVar = function() { return privateVar; }; } I want to have the following subclass which allows changing privateVar like so: function SubClass (arg1,arg2,arg3,privateVar) { //constructor code here then - var privateVar = privateVar; } SubClass.prototype = new BaseClass(); Now I want SubClass to inherit the getPrivateVar method. However, when I try this, it always returns 7500 which is the value in the BaseClass and not the value of privateVar. In other words, is it possible to inherit a BaseClass's public methods but have any references in them refer to the SubClass's properties? And how would I do that?

  • Is it possible to get the current request that is being served by node.js?

    - by user420504
    I am using express.js. I have a need to be able to log certain request data whenever someone tries to log a message. For this I would like to create a helper method like so function log_message(level, message){ winston.log(level, req.path + "" + message); } I would then use the method like so. exports.index = function(req, res){ log_message("info", "I'm here"); } Note that I am not passing the req object to the log_message function. I want that to be transparently done so that the log_message API user does not need to be aware of the common data that is being logged. Is there a way to achieve this with express.js/node.js. Is the request object available from a global variable of some sort?

  • Do i need a hashtag in Javascript to pass as a Div

    - by Mike
    How do i insert this php DivSomething into Javascript? Since Javascript needs a hashtag to recognize that as a div. Is there a way to tell JS that this is a Div or there's other better way to do it? Any help would be very much appreciated. <script> /*How do i insert a var DivSomething into JS with a hashtag */ /* DivSomething is php dynamic. It returns a Div. It can be #Div1, #Div2, #Div3... */ var DivSomething = '<?php echo $Highlight; ?>' $(function() { $('#MouseHere').hover(function() { $('#' + DivSomething).css('background-color', '#ffffff'); }, function() { // on mouseout, reset the background colour $('#' + DivSomething).css('background-color', ''); </script>

  • Toggleing between image

    - by Binaryrespawn
    Hi all, I have two images with which I am using in an anchor tag. I am using jquery toggle on the click event of the anchor tag to swap between images. $(document).ready(function(){ $('#registrationForm').hide(); $('#callform').append("<a id='formlink'>IMAGE 1</a>"); $("#formlink").click(function(){ $('#registrationForm').toggle(function(){ $('#formlink').empty().append(IMAGE 2); }); }); }); This works fine the first time around, however i want to toggle between the two images whenever the other is clicked. Any ideas ?

  • Best way to develop a secured application. With .net

    - by John S
    Hello, we are developing a windows application, and as most apps out there, there is a login form. What I don't like is that the login form validates the user and opens the main form if user and pass are correct. Simple as is. All the function calls etc are called without verifying the user and pass again, what should be the right thing to do. What's the best way to develop a secured application that if for any reason, the login form is by passed, the other function calls won't run? Some devs suggested that we include an user and pass params on each function, which seems to be wrong... thanks!

  • How to re-open a closed file descriptor

    - by chaitu
    I have a scenario where i created pipe for communication between two child and parent. Parent writes (using write function)data to the pipe and closes the respective file descriptor. The problem is when i want to write data again to the pipe, the write function is returning error code -1. I think its because writing end has been closed in previous iteration. Then how to open the corresponding file descriptor after it has been closed once. I tried using open() function which requires path to some file as arguement. But i am not using any files in my application. I have simple file descriptors (int arr[2]). Is it possible to achieve above scenario with pipes????

  • Constructors and method chaining in JavaScript

    - by Sethen Maleno
    I am trying to make method chaining work in conjunction with my constructors, but I am not exactly sure how to go about it. Here is my code thus far: function Points(one, two, three) { this.one = one; this.two = two; this.three = three; } Points.prototype = { add: function() { return this.result = this.one + this.two + this.three; }, multiply: function() { return this.result * 30; } } var some = new Points(1, 1, 1); console.log(some.add().multiply()); I am trying to call the multiply method on the return value of the add method. I know there is something obvious that I am not doing, but I am just not sure what it is. Any thoughts?

  • How can I use Javascript to access sub-elements?

    - by Steve
    I am dynamically creating forms dynamically according to a users actions. It is an entry-box and a two "buttons" for each instance. Each instance will be wrapped in a unique div tag. What I tried to do without success is when I dynamically create the "button" I attach a function with the input variable containing the div of its instance. This a brief excerpt: var newDivClass = document.getElementById("instance"+1); button1.innerHTML = "<a href=\"#\" onclick=\"buttons("+newDivClass+");\" id=\"button1\"> Button1 </a>"; function buttons(selected) { //I want this to select the first instance //of button1 found within div newDivClass selected.getElementById("button1"); //I also tried //this.getElementById("button1"); //selected.getChildren[0]; } The problem appears to be in passing newDivClass to the the actual function.

    - by muudless
    I currently have 2 obj and using the jquery extend function, however it's overriding value from keys with the same name. How can I add the values together instead? obj1 = {"orange":2,"apple":1, "grape":1} obj2 = {"orange":5,"apple":1, "banana":1} mergedObj = $.extend({}, obj1, obj2); var printObj = typeof JSON != "undefined" ? JSON.stringify : function(obj) { var arr = []; $.each(obj, function(key, val) { var next = key + ": "; next += $.isPlainObject(val) ? printObj(val) : val; arr.push( next ); }); return "{ " + arr.join(", ") + " }"; }; console.log('all together: '+printObj(mergedObj) ); And I get obj1 = {"orange":5,"apple":1, "grape":1, "banana":1} What I need is obj1 = {"orange":7,"apple":2, "grape":1, "banana":1}

  • Play Framework Form "fold" method naming rationale

    - by oym
    Play Framework's (2.x) Form class has a method called fold who's usage is indicated as: anyForm.bindFromRequest().fold( f => redisplayForm(f), t => handleValidFormSubmission(t) ) Essentially, the first function parameter is what gets executed on binding failure, and the 2nd on binding success. To me it seems similar to the 'success' and 'error' callbacks of jquery's ajax function. My question is why did the Play developers call the method "fold"? As a disclaimer I am new to Scala, but I am failing to see the connection between this and the functional Scala fold operation. The only similarity is that it is a higher order function; but I don't see any combining that is taking place, nor does it delegate internally in its implementation to any of the Scala fold functions.

  • Why hashCode() returns the same value for a object in all consecutive executions?

    - by Vijay Shanker
    Hi, I am trying some code around object equality in java. As I have read somewhere hashCode() is a number which is generated by applying the hash function. Hash Function can be different for each object but can also be same. At the object level, it returns the memory address of the object. Now, I have sample program, which I run 10 times, consecutively. Every time i run the program I get the same value as hash code. If hashCode() function returns the memory location for the object, how come the java(JVM) store the object at same memory address in the consecutive runs? Can you please give me some insight and your view over this issue?

  • Sum of a matrix, even or odd

    - by user1790201
    This function receives a numeric matrix represented as a list of rows, where each row is in turn a list. Assume that it is a square matrix: all rows have the same length and there are as many rows as elements in each row. Also assume that the matrix is at least of dimension 2 by 2 (i.e. minimally the matrix has 2 rows with 2 elements each) The function should return a list with as many elements as number of rows. Element i in the resulting list should have the sum of the values in row i. For example, if the matrix is 1 2 3 10 20 30 100 200 300 then this function should return the list [6,60,600] That is, addValuesInAllRows( [ [1,2,3], [10,20,30], [100,200,300] ] ) should return [6,60,600] Isn't this sort of similar but how would you sum up the list individually

  • How do submit an object to a struts2 action using jQuery?

    - by James Drinkard
    I have an object that I'm populating from a selection off a table row that a user selects. I have a jQuery function that captures the click event and a hidden form field populates an id I need. However, I'm not sure as to the proper way to send off that object to a struts2 action? I tried using this: $(function() { $('#tbl tr').click(function() { var id = $(this).closest('tr').find('input:hidden').val(); var page = "<s:url action='update/deleteInfo.action'/>?model.isDelete=true&model.info.id=id"; console.log(page); window.location.href=(page); }); }); The model object has an isDelete boolean variable and the model has a nested info object that has an id variable with getter/setters. However, when I send this across, the model object isn't populated with these entries. Is there a way to do this or a better way than the url tag?

  • jQuery extend $.fn and calling method syntax

    - by MBax
    I understand that you call a method like this when you are extending $.fn. ( $ == jQuery ) //$("div").myMethod(); $.fn.extend({ myMethod: function(){...} }); And like this when you extend the jQuery Object: //$.myMethod2(); $.extend({ myMethod2: function(){...} }); But I don't quite understand what the $() is doing here: $().functionName({ something: 'something' }).myMethod(); Does it have to do with the fact the method is being called including the function name? Thanks in advance and hope this makes sense.
