How To Cancel Input Box Event
Mar 24, 2010
I've been trying to do something and it's killing me because I can't figure out how to do it properly. I have an input box. I'm validating as the user types. Basically deleting forbidden characters as they type. I'm doing it with the onkeyup event. Problem is this looks kinda crappy because the character they type appears briefly and then get's deleted. I want to know how can I cancel the event that writes on the input box so that instead of deleting the character myself, I just cancel the event. I have no idea if the input box or the window is the one responsible for doing this.

I have this function I'm firing to execute the "delete" of an entry
Code JavaScript:
$(document).ready(function() {
$(".post_tools a.deletelink").click(function() {
var container = $(this).parents('.comment').attr("id");
var scriptLoc = $(this).attr("href");
[Code]...
The function executes the alert and if the user selects "OK" it completes successfully. However, if the user chooses to back out of the process when the alert fires by closing the alert, the function does not get canceled, it completes the delete of the comment. What do I need to do to make sure the user can successfully cancel this process when the warring is delivered?

I Have a text box in a jsp that is pre populated. The text box should accept only numbers and it should be greater than a minimum value (this value depends on the user settings). If the user enters a value less than the minimum value, i should pop up an alert saying that the value
entered is incorrect and reset it back to previous correct value. How could i do it using onchange event of the text box.

I've got to write some javascript to listen for a select 'change' event. Unfortunately, the select box has an onchange event as well. For example:
<select name="test" onchange="document.form.submit();">
Here's my event listener:
function handle_submit() {
return false;}
function addListeners() {
if (document.addEventListener) { document.form.test.addEventListener('change',handle_submit,false);
}}
window.onload = addListeners;
Now, the event listener does capture the event, but I want to cancel the onchange event within the select box. Is that possible?

building a tree using UL,LI tags as below. Issue seems with cancelling event bubbling. trying to cancel dragenter event to avoid dragenter firing for root LI. dragenter on image cancels bubbling. But dragenter on the child text bubbles and fires for Root. Whole purpose is to identify LI where its dropped. Edit: Noticed this is working as expected in IE6 and not working with IE8.

Doing web page with ASP/VB.NET. Have text boxes for UI on page. Two command buttons - Submit (for db update) and Cancel. I need the Cancel button to prompt the user to verify cancellation. Need OK/Cancel buttons on alert. If user selects Cancel-no action. If user selects OK then I want the text boxes cleared of user text input and focus returned to first text box. I think this may be the code but do not know how to apply it.
function Clear()
{
var res=window.confirm("Please confirm cancellation-text boxes will be cleared"); [code].....
Is this code valid or invalid for the events I need? How do I set it to fire when user clicks the ASP Cancel button?

I would to know If I have some input text with the same classname, can I add an event, for example onclick, for each of them without adding onclick="function();" in every input text in the code?
for example I have:
<input type="text" class="inputbox" name="text1">
<input type="text" class="inputbox" name="text2">
<input type="text" class="inputbox" name="text3">

I want to have a function on an event
<span id= "nameheader"> </span>
<form method ="post" action="send.php">
<input
id = "nameinput"
class = "input"
value = "name"
onfocus = "focus();"
onblur = "blur();"
/>
That is when you focus on the input box the value ' name' gets put above the box and when you focus on something else it goes back to the box.
this is my function
focus(){
document.getElementById('nameheader').innerHTML = 'name';
document.getElementById('nameinput').value = '';
}
And I would obviously do the opposite for onblur event.

I have a button on a page that is created with the <input> statement - this statement also contains the event handler onClick. The button displays correctly on the page but the event handler is not working - I know this as I put a simple alert at the beginning of the function PrcsBtn1.
<script type="text/javascript" language="javascript">
function PrcsBtn1()
{
var data2 = new Array();

I've noticed that the change event isn't fired on a text input when it's value is changed by JavaScript. It fires just fine when I type in the input and then lose focus. Example:
$(document).ready(function(){
$("#textinput").change(function(){
alert($(this).val());
[Code].....
I think have JavaScript which changes the value of the input dynamically.

I recently upgraded to jQuery 1.4 from 1.2.x and have found that the following code, which previously worked across all browsers, no longer works seamlessly in Internet Explorer:
<form id="myform">
<input type="file">
</form>
$('#myform input).change(function() { alert("Someone picked a file") });
In Firefox, this code continues to work like it did prior to 1.4, namely, as soon as the user picks a file, the change event fires. But in IE 7 (the only IE I've tested it in) the change event no longer fires, unless/until I click inside the browser window after choosing my file. I'm guessing it has something to do with the event not firing until something (not sure what... maybe the page itself?) gets focus.
Is this known/expected behavior with 1.4? If so, does anyone know how I can work around it to make 1.4 behave like 1.2.x did, where IE's change event will fire immediately after the file is picked without an extra click in the window?

I'm working on a quote generator and I'm running into an issue with onChange events not firing when a text field is dynamically populated via a child window. Here's my setup: I have 3 text boxes (quantity, price, markup) that are multiplied together in order to give the total of that product. Each text box has an onChange event [called calculator()] that calls an external javascript file, which handles the multiplication and instantly updates the total of that product. Up to this point, everything works fine - - when I manually edit any of the 3 inputs, the total updates correctly.
However, my problem is that I now have the "price" text box being dynamically populated, and when it updates it is not firing the onChange event attached to it. The text box is being filled by way of launching a child window and running the following code within it:

When I upgraded to jQuery 1.7.1 (from 1.5.x), I found that an exception was suddenly thrown on every keydown event on an INPUT type="text". I still get the exception when I remove my change and keyup events. Previously I bound to these elements with .live, but I have the same issue with the new .on, so I don't think this problem is even related to my bindings.
The exception is as follows (from the custom WebKit frame where my script runs):
This occurs on line 3255 of jquery-dev-1.7.1.js, which reads:
I did some poking around and found that handleObj.origType is "keydown". There is no jQuery.event.special["keydown"] defined, meaning that the first part of the expression evaluates to undefined (there is no such thing as {}.handle). The second part of the expression, handleObj.handler, evaluates to true. The entire expression therefore evaluates to true, which can't be applied as a function.

I'm trying to make the cursor focus on a certain input element when someone hits a certain key combo (such as Shift+S). Does anyone know how you attach a listener like that and bind it to a key combo?

I have a table with a date field in each row:
The table, and the input id element, are dynamically created from database records and I use jQuery live to initialize the datepicker for each field, like so:
The idea is that when I click in the input field, the datepicker pops up and allows the user to input a date. While the date shows in the input field in the table, the value attribute of the input field is empty. I can't use the getDate() method on the datepicker, since I can't programmatically connect the datepicker element in any particular row with the input element in that row. I tried the onClose method shown below, but that doesn't work either. Has anyone done this successfully?

I develop a form allow the user to upload with the hidden iframe.
While in the progress, I allow the user to cancel their upload. In
javascript, does it have cancel the request to the server. I have one
solution, but I don't like it. I remove the iframe element, so it
won't upload anymore. Do you any other solutions better than this?
