  • Buttons OnClick Event not firing when it causes a textboxes onChange event to fire first

    - by user48408
    I have a few textboxes and button to save their values on a webpage. The onchange event of the textboxes fires some js which adds the changed text to a js array. The ok button when clicked flushes this to the database via a webservice. This works fine except when the onchange event is caused by clicking the ok button. In this scenario the onchange of the textboxes still fires but the onClick event of the button does not. Any ideas? textboxes look something like <input name="ctrlJPView$tbcTabContainer$Details$JP_Details_Address2Text" type="text" value="test" id="ctrlJPView_tbcTabContainer_Details_JP_Details_Address2Text" onchange="addSaveDetails('Jobs###' + document.getElementById('ctrlJPView_tbcTabContainer_Details_JP_Details_Address2Text').value + ');" style="font-size:8pt;Left:110px;Top:29px;Width:420px;Height:13px;Position:absolute;" /> My save button <input type="button" name="ctrlJPView$btnOk" value="OK" onclick="saveAmendments();refreshJobGrids();return false;__doPostBack('ctrlJPView$btnOk','')" id="ctrlJPView_btnOk" class="ControlText" style="width:60px;" /> UPDATE: I guess this comes down to one of two things. 1) Something is happening before the onClick of the button gets called to surpress that call such as an inadvertent return false; or 2) the onClick event isn't firing at all. Now I've rem'd out everything actually inside the functions that are being called beforehand but the problem persists. But if i remove the call altogether it works (???)

  • javascript textbox call event when value changes

    - by Senica Gonzalez
    I have a textbox, and whenever the value of the box changes, I want to check and see if 20 digits have been entered. I thought that I would use the onChange event, but this seems to be interpreted as the onBlur event on IE. So then I thought I would use onKeyDown, but the problem comes in if the user wants to paste a value into the field, then the function never gets called. There are no other form boxes so I can't rely on onBlur or expect that they will change focus ever. How do I do this? I just want to evaluate the value of the textbox everytime the value of the textbox changes. <input type="text" onKeyDown="myfunction()">

  • Dynamic Jquery Accordion

    - by kwek-kwek
    How do I default an accordion to be closed on start-up. here is the sample view here Here is the code: <script> $(function() { $("#accordion").tabs("#accordion div.pane", {tabs: 'h3', effect: 'slide'}); }); </script> <script> // add new effect to the tabs $.tools.tabs.addEffect("slide", function(i, done) { // 1. upon hiding, the active pane has a ruby background color this.getPanes().slideUp("slow").css({backgroundColor: "#fff"}); // 2. after a pane is revealed, its background is set to its original color (transparent) this.getPanes().eq(i).slideDown("slow", function() { $(this).css({backgroundColor: 'transparent'}); // the supplied callback must be called after the effect has finished its job done.call(); }); }); </script>

  • jquery .submit live click runs more than once

    - by fxuser
    I use the following code to run my form ajax requests but when i use the live selector on a button i can see the ajax response fire 1 time, then if i re-try it 2 times, 3 times, 4 times and so on... I use .live because i also have a feature to add a post and that appears instantly so the user can remove it without refreshing the page... Then this leads to the above problem... using .click could solve this but it's not the ideal solution i'm looking for... jQuery.fn.postAjax = function(success_callback, show_confirm) { this.submit(function(e) { e.preventDefault(); if (show_confirm == true) { if (confirm('Are you sure you want to delete this item? You can\'t undo this.')) { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } } else { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } return false; }) return this; }; $(document).ready(function() { $(".delete_button").live('click', function() { $(this).parent().postAjax(function(data) { if (data.error == true) { } else { } }, true); }); });? EDIT: temporary solution is to change this.submit(function(e) { to this.unbind('submit').bind('submit',function(e) { the problem is how can i protect it for real because people who know how to use Firebug or the same tool on other browsers can easily alter my Javascript code and re-create the problem

  • Detecting a image 404 in javascript.

    - by xal
    After a user uploads a file we have to do some additional processing with the images such as resizing and upload to S3. This can take up to 10 extra seconds. Obviously we do this in a background. However, we want to show the user the result page immediately and simply show spinners in place until the images arrive in their permanent home on s3. I'm looking for a way to detect that a certain image failed to load correctly (404) in a cross browser way. If that happens, we want to use JS to show a spinner in it's place and reload the image every few seconds until it can be successfully loaded from s3.

  • Django foreign keys cascade deleting and "related_name" parameter (bug?)

    - by Wiseman
    In this topic I found a good way to prevent cascade deleting of relating objects, when it's not neccessary. class Factures(models.Model): idFacture = models.IntegerField(primary_key=True) idLettrage = models.ForeignKey('Lettrage', db_column='idLettrage', null=True, blank=True) class Paiements(models.Model): idPaiement = models.IntegerField(primary_key=True) idLettrage = models.ForeignKey('Lettrage', db_column='idLettrage', null=True, blank=True) class Lettrage(models.Model): idLettrage = models.IntegerField(primary_key=True) def delete(self): """Dettaches factures and paiements from current lettre before deleting""" self.factures_set.clear() self.paiements_set.clear() super(Lettrage, self).delete() But this method seems to fail when we are using ForeignKey field with "related_name" parameter. As it seems to me, "clear()" method works fine and saves the instance of "deassociated" object. But then, while deleting, django uses another memorized copy of this very object and since it's still associated with object we are trying to delete - whooooosh! ...bye-bye to relatives :) Database was arcitectured before me, and in somewhat odd way, so I can't escape these "related_names" in reasonable amount of time. Anybody heard about workaround for such a trouble?

  • How to test if raising an event results in a method being called conditional on value of parameters

    - by MattC
    I'm trying to write a unit test that will raise an event on a mock object which my test class is bound to. What I'm keen to test though is that when my test class gets it's eventhandler called it should only call a method on certain values of the eventhandlers parameters. My test seems to pass even if I comment the code that calls ProcessPriceUpdate(price); I'm in VS2005 so no lambdas please :( So... public delegate void PriceUpdateEventHandler(decimal price); public interface IPriceInterface{ event PriceUpdateEventHandler PriceUpdate; } public class TestClass { IPriceInterface priceInterface = null; TestClass(IPriceInterface priceInterface) { this.priceInterface = priceInterface; } public void Init() { priceInterface.PriceUpdate += OnPriceUpdate; } public void OnPriceUpdate(decimal price) { if(price > 0) ProcessPriceUpdate(price); } public void ProcessPriceUpdate(decimal price) { //do something with price } } And my test so far :s public void PriceUpdateEvent() { MockRepository mock = new MockRepository(); IPriceInterface pi = mock.DynamicMock<IPriceInterface>(); TestClass test = new TestClass(pi); decimal prc = 1M; IEventRaiser raiser; using (mock.Record()) { pi.PriceUpdate += null; raiser = LastCall.IgnoreArguments().GetEventRaiser(); Expect.Call(delegate { test.ProcessPriceUpdate(prc); }).Repeat.Once(); } using (mock.Playback()) { test.Init(); raiser.Raise(prc); } }

  • Use Javascript to retrieve HTML on same-domain

    - by ehfeng
    Say I have an xml document on a webserver (www.example.com/example.xml). On my main page, if I would like to retrieve that document as a string, how can I do this? I tried xmlhttprequest - maybe I'm using it wrong? It returns it as "undefined." Help? var xml_page = new XMLHttpRequest(); xml_page.open("GET", "http://www.samedomain.com/example.xml", true); if (xml_page.readyState == 4 && xml_page.status == 200) { var data = xml_page.responseText; } document.write(data);

  • IE8 (compatibility mode) won't load my Ajax content

    - by Jens Roland
    Hi all - I am working on a jQuery script on http://www.qxl.dk/ and I can't seem to get IE7 (or more accurately, IE8 in IE7 compatibility mode) to load my content. The sidebar box on the right named "QXL Aktuelt" loads its HTML content from an external file using Ajax load(), then triggers a custom jQuery event ("aktuelt_loaded") that starts a carousel script (like a scrolling newsticker). Several other content sections on the same page are loaded through Ajax and they work just fine, so I'm wondering what's going wrong. Everything works as expected in Firefox 3.6 and IE8, but not in IE8's compatibility mode. The script that loads the Ajax content is (inline on the page): <div id="qxlaktueltHolder"></div> <script type="text/javascript"> $("#qxlaktueltHolder").load("/contents/dk/modul/qxlaktuelt/qxlaktuelt.htm", function() { $("#qxlaktueltHolder").trigger("qxlaktuelt_loaded", []); }); </script> <script type='text/javascript' src='http://www.qxl.dk/contents/dk/js/jcarousellite_1.0.1.min.js'></script> <script type='text/javascript' src='http://www.qxl.dk/contents/dk/js/qxlaktuelt_liveload.js'></script> The external script that responds to the event is in the following file: http://www.qxl.dk/contents/dk/js/qxlaktuelt_liveload.js All ideas are very welcome.

  • Preventing focus on next form element after showing alert using JQuery

    - by digitalsanctum
    I have some text inputs which I'm validating when a user tabs to the next one. I would like the focus to stay on a problematic input after showing an alert. I can't seem to nail down the correct syntax to have JQuery do this. Instead the following code shows the alert then focuses on the next text input. How can I prevent tabbing to the next element after showing an alert? $('input.IosOverrideTextBox').bind({ blur: function(e) { var val = $(this).val(); if (val.length == 0) return; var pval = parseTicks(val); if (isNaN(pval) || pval == 0.0) { alert("Invalid override: " + val); return false; } }, focus: function() { $(this).select(); } });

    - by Kevin Lee
    I have a problem, everytime i type a text, it is overwriting what i have typed. i assume that the mode is set to overwriting, I want to insert the text not overwrite it, but i can't disable it because my insert key is mix up with my delete key so everytime i enter insert to disable the overwrite mode, it just delete what i type. so how to disable this? it's getting very annoying.. i'm using centOS.. and it seems that my problem is only related to netbeans because when i type here, it is set to insert mode.. but in netbeans, it just overwrites the codes! help!

  • VB.net Net after load event?

    - by themaninthesuitcase
    I need some way of knowing when a form has finished loading. My reasoning is I have a 2nd form that is loaded when this form loads. The code for this is called from form1.load. Form2 is currently being displayed behind form1 as I am guessing form1 calls an activate or similar at the end of the load so any Activate, BringToFront etc calls on from2 are over ridden. If you look at the code below I have tried adding frmAllocationSearch.Activate, frmAllocationSearch.BringToFront and Me.SendToBack after the call to ShowAlloactionSearchDialog() but these are all wasted as something is happening after the load event is fired to bring Me to the front. Code is: Private Sub Allocation_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load ShowAlloactionSearchDialog() End Sub Private Sub ShowAlloactionSearchDialog() If frmAllocationSearch Is Nothing OrElse frmAllocationSearch.IsDisposed Then frmAllocationSearch = New AllocationSearch frmAllocationSearch.MdiParent = Me.MdiParent frmAllocationSearch.Info = Me.Info frmAllocationSearch.Top = Me.Top frmAllocationSearch.Left = Me.Left + Me.Width - frmAllocationSearch.Width frmAllocationSearch.AllocationWindow = Me frmAllocationSearch.Show() Else If frmAllocationSearch.WindowState = FormWindowState.Minimized Then frmAllocationSearch.WindowState = FormWindowState.Normal frmAllocationSearch.Activate() End If End Sub

  • Javascript onunload form submit isn't submitting data

    - by Kevin
    I currently have form that checks if a user has unsubmitted changes when they leave the page with a function called through the onunload event. Here's the function: function saveOnExit() { var answer = confirm("You are about to leave the page. All unsaved work will be lost. Would you like to save now?"); if (answer) { document.main_form.submit(); } } And here's the form: <body onunload="saveOnExit()"> <form name="main_form" id="main_form" method="post" action="submit.php" onsubmit="saveScroll()"> <textarea name="comments"></textarea> <input type="submit" name="submit2" value="Submit!"/> </form> I'm not sure what I'm doing wrong here. The data gets submitted and saved in my database if I just press the submit button for the form. However, trying to submit the form through the onunload event doesn't result in anything being stored, from what I can tell. I've tried adding onclick alerts to the submitt button and onsubmit alerts to the form elements and I can verify that the submit button is being triggered and that the form does get submitted. However, nothing gets passed stored in the database. Any ideas as to what I'm doing wrong? Thanks.

  • Django: many-to-one fields and data integrity

    - by John
    Let's say that I have a Person who runs an inventory system. Each Person has some Cars, and each Car has a very large number of Parts (thousands, let's say). A Person, Bob, uses a Django form to create a Car. Now, Bob goes to create some Parts. It is only at the form level that Django knows that the Parts belong to some specific Car, and that the Parts.ForeignKey(Car) field should only have a specific Car as a choice. When creating a Part, you have to mess with the form's constructor or similar in order to limit the choice of Cars to only the cars owned by Bob. It does not seem proper that to enforce this ownership at the form level. It seems that other users' Cars must be inaccessible to anyone but the owner of the Car. What do you all think about this, and is there any way to enforce this?
