there is a button in my code. Apart from using mouse and clicking it, I'd like to fire (pressing ENTER) it after selecting it with TAB.
<div id="CloseButton" tabindex="0" onkeypress="return submitOnEnter(blah,event)">Close</div>
if it helps:
function submitOnEnter(blah,e) {
var keycode;
if (window.event) keycode = window.event.keyCode;
else if (e) keycode = e.which;
else return true;
if (keycode == 13) {
//at this point I need to fire a button w/o using its id
return false;
} else {
return true;
}
}
If someone knows how to do it?
Is it possible to make 'blah' refer to <div>, such that I could do:
$(blah).click();
this could work:
jQuery(':focus').click()
here is my solution:
part of HTML, close button is a div element and is a part of a modal window:
...
<div class="closeButton">
<span id="closeSpan" tabindex="0">Close</span>
</div>
...
JS, within the ModalWindow class:
$(modWin).find("#closeButton").one("click",
this.close).keypress(this.doNothing);
this.close = function () {
$("#modalWindow").css("display","none").fadeOut(200).html("");
$("#modalWindow #closeButton").hide();
$(window.self.document.body).find("#modalWindow").remove();
}
this.doNothing = function (e) {
var keycode;
if (window.event) keycode = window.event.keyCode;
else if (e) keycode = e.which;
else return true;
if (keycode == 13) {
innerthis.close();
return false;
} else {
return true;
}
}
PS: innerthis is defined within the ModalWindow class as:
var innerthis = this;

I am trying to disable right-click action on the scroll bar or remove the Inspect element option in the right-click menu window on my page. I am using the below code to fulfill my requirement. but where it is getting an issue that I am not able to find and other solution also not coming into mind. Please find my sample code below. Please Any help appreciated.
Sample Application - Using this link you can check the code.
<html oncontextmenu="return false;">
<head>
<style>
</style>
<script >
document.onkeypress = function (event) {
event = (event || window.event);
return keyFunction(event);
}
document.onmousedown = function (event) {
event = (event || window.event);
return keyFunction(event);
}
document.onkeydown = function (event) {
event = (event || window.event);
return keyFunction(event);
}
//Disable right click script
var message="Sorry, right-click has been disabled";
function clickIE() {if (document.all) {(message);return false;}}
function clickNS(e) {if
(document.layers||(document.getElementById&&!document.all)) {
if (e.which==2||e.which==3) {(message);return false;}}}
if (document.layers)
{document.captureEvents(Event.MOUSEDOWN);document.onmousedown=clickNS;}
else{document.onmouseup=clickNS;document.oncontextmenu=clickIE;}
document.oncontextmenu=new Function("return false")
function keyFunction(event){
//"F12" key
if (event.keyCode == 123) {
return false;
}
if (event.ctrlKey && event.shiftKey && event.keyCode == 73) {
return false;
}
//"J" key
if (event.ctrlKey && event.shiftKey && event.keyCode == 74) {
return false;
}
//"S" key
if (event.keyCode == 83) {
return false;
}
//"U" key
if (event.ctrlKey && event.keyCode == 85) {
return false;
}
//F5
if (event.keyCode == 116) {
return false;
}
}
</script>
</head>
<body >
<iframe style="width:100%" height="473" src="https://africau.edu/images/default/sample.pdf#toolbar=0"></iframe>
<div style="width:96%;height:473px;background-color:transparent;position:absolute;top:0px;max-width: 100%;">

The right click default behavior is to fire a contextmenu event whose default behavior is to display the context menu.
In order to prevent that default behavior, write this:
document.addEventListener('contextmenu', e => e.preventDefault());
Note that it won't prevent people from accessing developer tools with F12 and there is nothing you can do about this.
In my aspx page, I am also using two Modal Extender but the main problem is that when modal popup extender comes in front then still search button click I want that modal popups button should click on enter key when popup is shown.
I have set Default Enter Key Event in my page like this:
$(document).ready(function () {
$("body").bind("keydown", function (event) {
var keycode = (event.keyCode ? event.keyCode : (event.which ? event.which : event.charCode));
if (keycode == 13) {
document.getElementById('btnSearch').click();
return false;
} else {
return true;
}
});
and it's working good.
But the problem is that I have also two ModalPopupExtender on my Page
with Id = ModalPopupExtender1 and Id = ModalPopupExtender2.
Now I want when My ModalPopupExtender1 called then button with ID = "btnMUpdate" should click on enter key.
and when my ModalPopupExtender2 called then
button with ID = "btnConfirm" should click on enter key.
$(document).ready(function () {
this.ModalPopupExtender1.add_showing(show1);
this.ModalPopupExtender2.add_showing(show2);
this.ModalPopupExtender1.add_hiding(hide1);
this.ModalPopupExtender2.add_hiding(hide2);
$("body").bind("keydown", function (event) {
var keycode = (event.keyCode ? event.keyCode : (event.which ? event.which : event.charCode));
if (keycode == 13) {
if (this.ModalPopupExtender1IsShown) {
document.getElementById('btnMUpdate').click();
} else if (this.ModalPopupExtender2IsShown) {
document.getElementById('btnConfirm').click();
} else {
document.getElementById('btnSearch').click();
}
return false;
} else {
return true;
}
});
function show1() {
this.ModalPopupExtender1IsShown = true;
}
function show2() {
this.ModalPopupExtender2IsShown = true;
}
function hide1() {
this.ModalPopupExtender1IsShown = false;
}
function hide2() {
this.ModalPopupExtender2IsShown = false;
}
On each ModalPopupExtender you can put a callback on show and hide events
i come across this and that worked fine for me
<ajaxToolkit:ModalPopupExtender ID="ModalPopupExtender3" runat="server"
PopupControlID="PanelMsg" TargetControlID="lnkdummy3" BackgroundCssClass="modalBackground" >
</ajaxToolkit:ModalPopupExtender>
<asp:Panel ID="PanelMsg" DefaultButton="btnMSend" runat="server" Style="display: none;background-color:#e0e0e0">
</asp:Panel>
given modal extender panel DefaultButton="btnMSend" and that worked fine
I've looked on the internet for this and all I can find are depreciated functions so before posting please check to make sure that the code you suggest isn't depreciated.
I've found this and tried it:
https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/KeyboardEvent
$(document).ready(function () {
var x = new KeyboardEvent("FormatCode", deprectiatedArgument);
});
But after further inspection the KeyboardEventInit is depreciated.
I would like to create an event on pres of the CTRL + K keys.
You have a specific key code for every button on the keyboard.
All of them are here http://keycode.info/.
$(document).keyup(function(e) {
if (e.keyCode === 13) function(); // enter
if (e.keyCode === 27) function(); // esc
});
Here's a vanilla JS solution to detect a CTRL + k keypress event:
UPDATED to also trigger the event.
document.addEventListener("keypress", function(e) {
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 11 || e.keyCode == 75)) {
alert("ctrl+k!");
}
});
document.getElementById("trigger").addEventListener("click", function(){
//trigger a keypress event...
var e = document.createEvent('HTMLEvents');
e.initEvent("keypress", false, true);
e.ctrlKey = true;
e.keyCode = 75;
document.dispatchEvent(e);
});
Press <kbd>ctrl+k</kbd> or
trigger the event
you can use a library called shortcut.js .. here is a link to their source code for downloading:
http://www.openjs.com/scripts/events/keyboard_shortcuts/shortcut.js
then run ur code by making this function:
shortcut.add("Ctrl+K",function() {
alert("Hi there!");
});
and here is the documentation : http://www.openjs.com/scripts/events/keyboard_shortcuts/
hope that can help.
$(document).ready(function () {
var bool = false;
$(document).keydown(function (e) {
if (e.keyCode === 17) {
bool = true;
}
if (bool == true && e.keyCode == 75) {
alert("");
}
});
$(document).keyup(function (e) {
if (e.keyCode === 17) {
bool = false;
}
});
});
This is how me and a friend got it working
I need to disable shift keypress event in my site by using JavaScript or any other method.
Below is my code:
$(document).ready(function() {
document.onkeydown = checkKeycode
function checkKeycode(e) {
var keycode;
if (window.event) {
keycode = window.event.keyCode;
}
else if (e) {
keycode = e.which;
}
//alert(keycode);
if (keycode == 16) {
alert(keycode);
return false;
}
}
});
// bind an event listener to the keydown event on the window
window.addEventListener('keydown', function (event) {
// if the keyCode is 16 ( shift key was pressed )
if (event.keyCode === 16) {
// prevent default behaviour
event.preventDefault();
return false;
}
});
http://api.jquery.com/keypress/
In addition, modifier keys (such as Shift) trigger keydown events but not keypress events.
Try this
$('#target').keydown(function(event) {
if (event.shiftKey) {
event.preventDefault();
}
}
document.onkeydown = function (e) {
var e = e || event;
if (e.shiftKey === true) {
return false;
}
};
You may try this:
jQuery(document).keydown(function(e){
if(e.which === 16) {
e.preventDefault();
return;
}
console.log(e.which);
});
See demo.
Use Firebug and check console output.
I have the following simple javascript code, which handles the Return Key, I don't want to submit the form when the return key is pressed in the textbox.
All this works fine, but in Firefox, if i show an alert message, then it stops working and the form starts getting submitted, whereas the exact code without alert message works fine and stops the form from being submitted. I dont understand why alert is spoiling the party..
$("document").ready(function () {
$("#input1").keydown(OnKeyDown);
});
function OnKeyDown(e) {
if (e.keyCode == 13) {
// alert('this will fail'); // Adding alert makes the form submit
stopBubble(e);
return false;
}
}
function stopBubble (e) {
// If an event object is provided, then this is a non-IE browser
if (e && e.stopPropagation)
// and therefore it supports the W3C stopPropagation() method
e.stopPropagation();
else
// Otherwise, we need to use the Internet Explorer
// way of cancelling event bubbling
window.event.cancelBubble = true;
}
<input type="text" id="input1" value="">
I don't really know if the event is normalized or not. But this is how I have to do it for it to work in all browsers:
$(whatever).keypress(function (e) {
var k = e.keyCode || e.which;
if (k == 13) {
return false; // !!!
}
});
jQuery normalizes this already, you can just do:
$(document).ready(function () {
$("#input1").keydown(OnKeyDown);
});
function OnKeyDown(e) {
if (e.which == 13) { //e.which is also normalized
alert('this will fail');
return false;
}
}
When you do return false from a handler, jQuery calls event.preventDefault() and event.stopPropgation() internally already. You can also do the anonymous function version:
$(function () {
$("#input1").keydown(function() {
if (e.which == 13) return false;
});
});
textBox.onkeydown = function (e) {
e = e || window.event;
if (e.keyCode == 13) {
if (typeof (e.preventDefault) == 'function') e.preventDefault();
if (typeof (e.stopPropagation) == 'function') e.stopPropagation();
if (typeof (e.stopImmediatePropagation) == 'function') e.stopImmediatePropagation();
e.cancelBubble = true;
return false;
}
}
