We Keep Coding

Changing input value inside "input" event handler prevents "change" event firing in Chrome and IE (but not in Firefox)

In the following code I have "input" event handler that changes the value of the input as the user types. I also have "change" event handler to keep track of any changes made to this field. For some reason "change" event doesn't fire in Chrome and IE when the user leaves the field. Why is that and how to make it work in all major browsers?
Also note that it's not acceptable to trigger "change" event manually every time "input" event fires.
EDIT: "change" event seems to fire in Chrome only if transform function does not change the resulting string in any way. So if I type lower case letters and focus out after every character, "change" fires only for indexes 0, 2, 4 ...
Link to fiddle: http://jsfiddle.net/3hqxx2pr/
function transform(s) {
var r = "";
for (var i = 0; i < s.length; i++) {
r += i & 1 ? s[i].toUpperCase() : s[i];
}
return r;
}
$(document).ready(function(){
$("#in").on("change", function() {
console.log("changed"); // works only in ff
});
$("#in").on("input propertychange", function() {
$("#in").val(transform($("#in").val()));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<input id="in"/>

Trigger change yourself
$("#in").val(transform($("#in").val())).change();
or
$("#in").val(transform($("#in").val())).trigger("change");
Based on a edit and restriction you made:
$("#in").on("input propertychange", function() {
var inp = $(this);
var orgVal = inp.val();
var transVal = transform(orgVal);
if (orgVal !== transVal) {
inp.val(transVal).trigger("change");
}
});

JS onkeydown/onkeyup - convert to jQuery keydown/keyup

I currently have some js for phone number validation that is using inline event listeners in the input field. I need to change this example so that instead of attaching the event listeners inline, I would be targeting the DOM element in jQuery and adding the event listeners. Here's a working example of what I have so far: http://jsfiddle.net/yVdgL/21/
window.mask = function (e,f){
var len = f.value.length;
var key = whichKey(e);
if((key>=47 && key<=58) || (key>=96 && key<=105))
{
if( len==1 )f.value='('+f.value
else if(len==4 )f.value=f.value+')'
else if(len==8 )f.value=f.value+'-'
else f.value=f.value;
}
}
function whichKey(e) {
var code;
if (!e) var e = window.event;
if (e.keyCode) code = e.keyCode;
else if (e.which) code = e.which;
return code
}
and
<input type="text" name="phone" id="phone" onkeydown="mask(event,this)" onkeyup="mask(event,this)" maxlength="13" />
I tried this but was unable to achieve the functionality that I need.

i have update you jsfiddle example:-
jQuery(document).ready(function(){
jQuery('#edit-phone1').keyup(function(event){
mask(event,this);
});
jQuery('#edit-phone1').keydown(function(event){
mask(event,this);
});
});
click here to see working example:-
http://jsfiddle.net/yVdgL/38/
or you can try :-
$(document).ready(function() {
$('#edit-phone1').on("keyup keydown", function(e) {
mask(e, this);
});
});
link for this is:-http://jsfiddle.net/yVdgL/56/

In older, pre-HTML5 browsers, $("#phone").keyup( function ) or keydown is definitely what you're looking for.
In HTML5 there is a new event, "input", which behaves exactly like you seem to think "change" should have behaved - in that it fires as soon as a key is pressed to enter information into a form. $("#phone").bind('input',function);

You never defined event.
jQuery('#edit-phone1').keyup(function(){
jQuery('#edit-phone1').mask(event,this); //<-- what is event?
});
just add it
Second issue is you are treating window.mask like a jQuery plugin and it is not a plugin.
jQuery('#edit-phone1').keyup(function(event){ //<-- add event here
mask(event,this);
});

KeyboardState.pressed is always true after .prompt or alert - Why?

As the title says, I have tried THREEx and Stemkovskis standalone KeyboardState.js , and neither of them seems to update properly.
This is my code:
m_vKeyboard = new THREEx.KeyboardState();
// m_vKeyboard.update(); // if using stemkovskis
if (m_vKeyboard.pressed("F")) {
alert("And now it is always true!");
}
you click the F key once, release it; alert window pops up, click OK, it pops up again for all eternity. How come?

Many browsers repeat keydown. Read more here and here (ctrl+f : auto-repeat).
Here's a proposed solution for your specific problem :
A. when keydown store its state as true in some array and make it false on keyup.
wasPressed['F'] = true; //on keydown
wasPressed['F'] = false; //on keyup
B. when checking for next keydown check its state as well.
if (m_vKeyboard.pressed("F") && !wasPressed['F'])
Find full implementation : Here
UPDATE
var wasPressed = {};
if( keyboard.pressed('F') && !wasPressed['f'] ){
alert("F was pressed");
prompt("Enter data : ");
wasPressed['f'] = true;
}
UPDATE 2
keyboard.domElement.addEventListener('keydown', function(event){
wasPressed = {};
})

I'm wondering if it has something to do with alert() being a blocking call. Using the code below gives me your same issue. If I comment out the alert() and un-comment the console.log() it seems to work fine. However, I'm not sure if that helps your issue.
var m_vKeyboard = new THREEx.KeyboardState();
setInterval(function () {
var key = "F";
var pressed = m_vKeyboard.pressed(key);
alert("And now it is always true!");
//console.log("key", key, "pressed", pressed);
}, 100);

Just add this to the beginning of onKeyDown in KeyboardState.js:
if (event.repeat) return;

Event fired when clearing text input on IE10 with clear icon

On chrome, the "search" event is fired on search inputs when user clicks the clear button.
Is there a way to capture the same event in javascript on Internet Explorer 10?

The only solution I finally found:
// There are 2 events fired on input element when clicking on the clear button:
// mousedown and mouseup.
$("input").bind("mouseup", function(e){
var $input = $(this),
oldValue = $input.val();
if (oldValue == "") return;
// When this event is fired after clicking on the clear button
// the value is not cleared yet. We have to wait for it.
setTimeout(function(){
var newValue = $input.val();
if (newValue == ""){
// Gotcha
$input.trigger("cleared");
}
}, 1);
});

The oninput event fires with this.value set to an empty string. This solved the problem for me, since I want to execute the same action whether they clear the search box with the X or by backspacing. This works in IE 10 only.

Use input instead. It works with the same behaviour under all the browsers.
$(some-input).on("input", function() {
// update panel
});

Why not
$("input").bind('input propertychange', function() {
if (this.value == ""){
$input.trigger("cleared");
}
});

I realize this question has been answered, but the accepted answer did not work in our situation. IE10 did not recognize/fire the $input.trigger("cleared"); statement.
Our final solution replaced that statement with a keydown event on the ENTER key (code 13). For posterity, this is what worked in our case:
$('input[type="text"]').bind("mouseup", function(event) {
var $input = $(this);
var oldValue = $input.val();
if (oldValue == "") {
return;
}
setTimeout(function() {
var newValue = $input.val();
if (newValue == "") {
var enterEvent = $.Event("keydown");
enterEvent.which = 13;
$input.trigger(enterEvent);
}
}, 1);
});
In addition, we wanted to apply this binding only to the "search" inputs, not every input on the page. Naturally, IE made this difficult as well... although we had coded <input type="search"...>, IE rendered them as type="text". That's why the jQuery selector references the type="text".
Cheers!

We can just listen to the input event. Please see the reference for details. This is how I fixed an issue with clear button in Sencha ExtJS on IE:
Ext.define('Override.Ext.form.field.ComboBox', {
override: 'Ext.form.field.ComboBox',
onRender: function () {
this.callParent();
var me = this;
this.inputEl.dom.addEventListener('input', function () {
// do things here
});
}
});

An out of the box solution is to just get rid of the X entirely with CSS:
::-ms-clear { display: none; } /* see https://stackoverflow.com/questions/14007655 */
This has the following benefits:
Much simpler solution - fits on one line
Applies to all inputs so you don't have to have a handler for each input
No risk of breaking javascript with bug in logic (less QA necessary)
Standardizes behavior across browsers - makes IE behave same as chrome in that chrome does not have the X

for my asp.net server control
<asp:TextBox ID="tbSearchName" runat="server" oninput="jsfun_tbSearchName_onchange();"></asp:TextBox>
js
function jsfun_tbSearchName_onchange() {
if (objTbNameSearch.value.trim() == '')
objBTSubmitSearch.setAttribute('disabled', true);
else
objBTSubmitSearch.removeAttribute('disabled');
return false;
}
ref
MSDN onchange event
- tested in IE10.
... or to hide with CSS :
input[type=text]::-ms-clear { display: none; }

The above code was not working in my case and I have changed one line and introduced $input.typeahead('val', ''); which works in my case..
// There are 2 events fired on input element when clicking on the clear button:// mousedown and mouseup.
$("input").on('mouseup', function(e){
var $input = $(this),
oldValue = $input.val();
if (oldValue === ''){
return;
}
// When this event is fired after clicking on the clear button // the value is not cleared yet. We have to wait for it.
setTimeout(function(){
var newValue = $input.val();
if (newValue === ''){
$input.typeahead('val', '');
e.preventDefault();
}
}, 1);
});

jQuery - triggering multiple events one by one

I'm using jquery tagsInput plugin where I need to dynamically modify the query(deleting the query or entering the new query) without actually typing in the search box connected with tagsInput plugin.
My problem here is I want to trigger backspace event at first then enter event next. Here is the code.
function triggering_events() {
$(".tag").each(function() {
var e = jQuery.Event("keydown");
e.keyCode = 8;
e.which = 8;
$("#input-search_tag").trigger(e); //triggering backspace event
});
var input = $("#input-search_tag");
input.val("food");
input.trigger(e); //triggering enter event
}
But only the backspace event is triggering from the above code. How can I make that enter event work?
Could anyone point out the mistake I've done?
Thanks!

you can try use the methods removeTag and addTag for remove and add tag's:
function triggering_events() {
var
idInput = 'input-search',
input = $("#" + idInput);
$("#"+idInput+"_tagsinput .tag").each(function() {
var tag = $.trim($(this).find('span:eq(0)').text());
input.removeTag(tag);
});
input.addTag("food");
}
run

There is an issue here:
$("#input-search_tag").val("food").trigger(e); //triggering enter event
.val() returns you a string value of the jquery Element, it is not a chainable method. strings do not have a trigger method.
You could fix this by splitting it into two calls:
var input = $("#input-search_tag");
input.val("food");
input.trigger(e); // triggering enter event
Or using .end():
$("#input-search_tag").val("food").end().trigger(e); //triggering enter event
Edit: putting it all together, along with reusing one event instead of creating multiples:
function triggering_events() {
var e = jQuery.Event("keydown");
e.which = 8;
$(".tag").each(function() {
$("#input-search_tag").trigger(e); // triggering backspace event
});
e.which = 13;
$("#input-search_tag").val("food").end().trigger(e); // triggering enter event
}
