  • jquery Troubles with binding to an element by id

    - by Alonzo
    Hi What im trying to do is that when the esc key is pressed on the text input field (id = txtSearch), some code will run. this is my code: $(document).ready(function() { $('#txtSearch').bind('keyup', function(e) { var characterCode; // literal character code will be stored in this variable if (e && e.which) { //if which property of event object is supported (NN4) e = e; characterCode = e.which; } else { characterCode = e.keyCode; } if (characterCode == 27) //if esc key { //do stuff } }); } It doesnt work for me. however, if i would change that line: $('#txtSearch').bind('keyup', function(e) { with: $(document).bind('keyup', function(e) { everything works. but i dont want to bind the keyup with esc to the whole document... any suggestions on how i can bind the the keyup only with the specific text search element? (or its containing div or something) Thanks!

  • .NET-MVC Modelbinder not binding because of primary key, all other fields are right. What's happenin

    - by ropstah
    I want to perform an Add object scenario in .NET using the modelbinder. Function AddObject() As ActionResult Return View() End Function <AcceptVerbs(HttpVerbs.Post)> _ Function AddObject(<Bind(Exclude:="ObjectId")> ByVal o As BLL.Object) As ActionResult o.Save() End Function However, I get an error: 'o.ObjectId' is not declared or the module containing it is not loaded in the debugging session. While inspecting the object, all other fields are set properly. I've tried all combinations regarding: with/without Html.Hidden("ObjectId") to with/without <Bind(Exclude:="ObjectId")> and even setting o.ObjectId to Nothing, all with the same results. What am I doing wrong?

  • Cannot get document.getElementByID to work

    - by user1804234
    The following function doesn't work for some reason. Can someone see what the problem is? function checkMaxLen(txt, maxLen) { var actualLen = txt.value.length; var remain = maxLen - actualLen; document.getElementById('remainChar').Value = remain; } <input type="text" id="remainChar" runat="server" value="500"/> Whenever I try to run the function, I get this error: Microsoft JScript runtime error: Unable to set value of the property 'Value': object is null or undefined

  • finding last loop through a jQuery object

    - by DA
    Sample jquery. Assume $cog is a cached selector of multiple items. $cog.fadeOut('slow',function(){ alert('hey'); }) In that example, of $cog is a jQuery object of 4 DOM elements, the above will fade each element out one by one, and trigger an alert each time on the callback (4 alerts). I'd like to only call the alert when all 4 elements are done with their fadeOut function. This: $cog.fadeOut('slow',function(){ }) alert('hey'); when run, will show an alert, then the $cog elements disappear (I'm guessing due to timing issues with the fadeOut animation) Is there a way when calling a function against multiple DOM objects in a jQuery object to know when it's done with the last item?

  • MATLAB: Designing a "Warm Start"

    - by squall14414
    I'm currently coding a function in MATLAB that has two steps: It processes some data It does some calculations on the processed data I'm using the function to run a series of experiments, where I tweak the way calculations occur in step 2). Seeing how I'm working with a large dataset and the data processing step takes a while each time, however, I'm wondering whether there is anyway to code in a "warm start" in the function. That is to say, is there anyway to save all the progress that I've done after step 1) so that if I run the function a second or third time, it can skip step 1) and go right to step 2)?

  • jQuery toggle() with unknown initial state

    - by Jason Morhardt
    I have a project that I am working on that uses a little image to mark a record as a favorite on multiple rows in a table. The data gets pulled from a DB and the image is based on whether or not that item is a favorite. One image for a favorite, a different image if not a favorite. I want the user to be able to toggle the image and make it a favorite or not. Here's my code: $(function () { $('.FavoriteToggle').toggle( function () { $(this).find("img").attr({src:"../../images/icons/favorite.png"}); var ListText = $(this).find('.FavoriteToggleIcon').attr("title"); var ListID = ListText.match(/\d+/); $.ajax({ url: "include/AJAX.inc.php", type: "GET", data: "action=favorite&ItemType=0&ItemID=" + ListID, success: function () {} }); }, function () { $(this).find("img").attr({src:"../../images/icons/favorite_not.png"}); var ListText = $(this).find('.FavoriteToggleIcon').attr("title"); var ListID = ListText.match(/\d+/); $.ajax({ url: "include/AJAX.inc.php", type: "GET", data: "action=favorite&ItemType=0&ItemID=" + ListID, success: function () {} }); } ); }); Works great if the initial state is not a favorite. But you have to double click to get the image to change if it IS a favorite initially. This causes the AJAX to fire twice and essentially make it a favorite then not a favorite before the image responds. The user thinks he's made it a favorite because the image changed, but in fact, it's not. Help anybody?

  • jQuery won't parse xml with nodes called option

    - by user170902
    hi all, I'm using jQuery to parse some XML, like so: function enumOptions(xml) { $(xml).find("animal").each(function(){ alert($(this).text()); }); } enumOptions("<root><animal>cow</animal><animal>squirrel</animal></root>"); This works great. However if I try and look for nodes called "option" then it doesn't work: function enumOptions(xml) { $(xml).find("option").each(function(){ alert($(this).text()); }); } enumOptions("<root><option>cow</option><option>squirrel</option></root>"); There's no error, just nothing gets alerted, as if the find isn't finding anything. It only does it for nodes called option everything else I tested works ok! I'm using the current version of jQuery - 1.4.2. Anyone any idea? TIA. bg

  • Difficulty with jQuery and input keydown event

    - by Rosarch
    I am making a simple JavaScript enhanced list. I want it to be a list of inputs, each with an 'Add' and 'Remove' button. If the user clicks 'Add', a new li will be added. If the user clicks 'Remove', that li will be removed. It works fine, except for hitting "enter" in an <input>. Currently, it always causes the Remove.click event handler to fire, unless there's only one item in the list. I'm not sure why. How can I suppress this? Here is the complete jQuery. My attempt to fix the "enter" issue is commented out, and it doesn't work. I suspect that I could be designing this code better; if you see an improvement I'd love to hear it. function make_smart_list(list) { var ADD_CLASS = 'foo-widget-Add'; var REMOVE_CLASS = 'foo-widget-Remove'; var jq_list = $(list); jq_list.parents('form').submit(function() { return false; }); function refresh_handlers() { jq_list.find(sprintf('.%s, .%s', REMOVE_CLASS, ADD_CLASS)).unbind('click'); // jq_list.find('input').unbind('submit'); // // jq_list.find('input').submit(function() { // var jq_this = $(this); // var next_button = jq_this.nextAll('button'); // if (next_button.hasClass(ADD_CLASS)) { // next_button.nextAll('button').click(); // return; // } // // if (next_button.hasClass(REMOVE_CLASS)) { // return false; // } // // }); jq_list.find("." + REMOVE_CLASS).click(function() { var jq_this = $(this); jq_this.parent().remove(); refresh_handlers(); return false; }); jq_list.find("." + ADD_CLASS).click(function() { var jq_this = $(this); if (jq_this.prevAll('input').val() == '') { return; } jq_this.parent().clone().appendTo(jq_this.parent().parent()); jq_this.parent().next().find('input').val('').focus(); jq_this.removeClass(ADD_CLASS).addClass(REMOVE_CLASS); jq_this.text('Remove'); refresh_handlers(); return false; }); } refresh_handlers(); } (sprintf is another script I have.)

  • Do preconditions ALWAYS have to be checked?

    - by Pin
    These days I'm used to checking every single precondition for every function since I got the habit from an OS programming course back at uni. On the other hand, at the software engineering course we were taught that a common precondition should only be checked once, so for example, if a function is delegating to another function, the first function should check them but checking them again in the second one is redundant. I do see the redundancy point, but I certainly feel it's safer to always check them, plus you don't have to keep track of where they were checked previously. What's the best practice here?

  • C/C++ definitions of functions

    - by Vit
    Yesterday, I have been watching discussion here, about compilers and linkers. It was about C library function definitions. I have never thought of that, so it inspired me to do some searching, but I cannot find exactly what I want. I wonder, what is the smallest syntax you need to add into your source code to enable just printf() function. I mean the function declaration from stdio.h you need.

  • Unable to call views

    - by Scott
    I'm using Sails and I when I attempt to call the login action of my UsersController. I know my routing is working, because the console.log successfully logs both the loginpassword and loginname. However, the res.view() doesn't work. Neither does returning res.view(). module.exports = { create: function(req, res) { }, destroy: function(req, res) { }, login: function(req, res) { var loginname = req.param("loginname"); var loginpassword = req.param("loginpassword"); console.log(loginname + ' ' + loginpassword); res.view(); }, logout: function(req, res) { }, _config: {} }; I have a /views/user/login.ejs and all it currently contains is a header block with some test text, but I can't get that to render at all. Any thoughts?

  • function_exists php

    - by user527800
    Hi all I'm trying to write a function that could receive it's second arg a name of a function. In order to validate function's name (that will be used in an eval statement) I use function_exists such as: if(function_exists($type)){ $toEval= $type.'(\''.$file.'\');'; }else{ But if the arg sent is include or require (with 'once' variations) this code fails (function_exists returns false). How could this be fixed? Thanks, Alex

  • Obtaining frame pointer in C

    - by assketchum
    I'm trying to get the FP in my C program, I tried two different ways, but they both differ from what I get when I run GDB. The first way I tried, I made a protocol function in C for the Assembly function: int* getEbp(); and my code looks like this: int* ebp = getEbp(); printf("ebp: %08x\n", ebp); // value i get here is 0xbfe2db58 while( esp <= ebp ) esp -= 4; printf( "ebp: %08x, esp" ); //value i get here is 0xbfe2daec My assembly code getEbp: movl %ebp, %eax ret I tried making the prototype function to just return an int, but that also doesn't match up with my GDB output. We are using x86 assembly. EDIT: typos, and my getEsp function looks exactly like the other one: getEsp: movl %esp, %eax ret

  • Remove the hash after Ajax loading (I'm ajaxing wordpress 8-) )

    - by Alberto
    Hi everybody, I followed this great tutorial to"ajax" my blog:http://www.deluxeblogtips.com/2010/05/how-to-ajaxify-wordpress-theme.html But it creates some problems and I think the problem is in the hash that ajax creates. So, after the content is loaded, how can I remove the hash from the url? I copy my code here: jQuery(document).ready(function($) { var $mainContent = $("#content"), siteUrl = "http://" + top.location.host.toString(), url = ''; $(document).delegate("a[href^='"+siteUrl+"']:not([href*=/wp-admin/]):not([href*=/wp-login.php]):not([href$=/feed/]):not([href*=/go.php]):not(.comment-reply-link)", "click", function() { location.hash = this.pathname; $('html, body').animate({scrollTop:0}, 'fast'); return false; }); $("#searchform").submit(function(e) { location.hash = '?s=' + $("#search").val(); e.preventDefault(); }); $(window).bind('hashchange', function(){ url = window.location.hash.substring(1); if (!url) { return; } url = url + " #inside"; $mainContent.html('<div id="loader">Caricamento in corso...</div>').load(url, function() { //$mainContent.animate({opacity: "1"}); scriptss(); }); }); $(window).trigger('hashchange'); }); Thank all very much!

  • onclick from an Object's button doesn't work

    - by 730
    I instantiate an object, with an argument which is a button. When the button of an instance is clicked, it should run a function, but it doesn't. In the full version of the code, Chrome gives this message in the console: "Uncaught TypeError: Cannot read property 'onclick' of undefined" HTML: <textarea id='txt' readonly rows='5' cols='40'></textarea> <button id='btn' type='button'>click</button> JS: var btn = document.getElementById('btn'); var txt = document.getElementById('txt'); var foo = new Foo(btn); function Foo(btn) { this.button = btn; } Foo.prototype.buy = function() { txt.value = 'Foo Bar'; }; Foo.button.onclick = function() { foo.buy(); }; Fiddle

  • (jquery): After Ajax: success, how to limit parsing in pieces and insert piece by piece into the DOM

    - by Johua
    Let's say on ajax success the function: xmlParser(xml) is called and the XML response contains about 1500 xml elements (for example: ...) Inside it looks like: function xmlParser(xml){ var xmlDOM = $(xml); // dom object containing xml response xdom.find("book").each(function(){ var $node = $(this); // parsing all the <book> nodes }); } How can you say: parse only first 20 nodes from the xml response, do something with them. And you have a button,..when clicked parses the next 20 nodes...and so on. So bassically, is there something like: children(20)....and a function wich will parse the next 20 nodes onClick. thx

  • Problem with $.get while submitting form

    - by bradenkeith
    I'm trying to verify that an Account Name is not already in use once a user fills out a form. The code looks like: $("#add_account").submit( function () { $.get( "'.url::site("ajax/check_account_name").'", {account_name: "t"}, function(data){ alert( data ); }); }); I get a $.get response if the statement sits like this: $(document).ready( function () { $.get( "'.url::site("ajax/check_account_name").'", {account_name: "t"}, function(data){ alert( data ); }); }); Which leads me to believe that my $.get statement is correct. Is there some jQuery rule I'm not familiar with that would cause this to fail in on submit scenario? In code block 1, I get values returned like they should. Block 2 gives me a blank response. Any ideas? Thanks for your time, I know you have better things to be doing.

  • VS JavaScript intellisense with paramaters

    - by TonyB
    here is some sample javascript: SomeObjectType = function() { } SomeObjectType.prototype = { field1: null, field2: null } SomeOtherObject = function() { } SomeOtherObject.prototype = { doSomething: function(val) { /// <param name="val" type="SomeObjectType"></param> var val2 = new SomeObjectType(); //val2. shows intellisense correctly //val1. does NOT } } Shouldn't visual studio be giving me intellisence when i do "val." inside the "doSomething" function? I would expect it to give me field1 and field2 as options, but it doesn't. I DO get field1 and field2 if I type "val2." so intellisence works when I create a new object of the same type that I specify in the param comment. Any ideas what I am doing wrong or is this just not supported?
