How to trigger an action when focusing an input but the focus event not come from click?
$('#input').focus(function(){
if(not come from click)
{
alert('Holla!');
}
});
To tell between "focus" events that come from keyboard and those that come from mouse, you can track the mouse events.
First, to understand the sequence of events that happen when you click an input, or Tab into it, look at the following jsfiddle: http://jsfiddle.net/orlenko/fyFkk/
In it, we'll log mousedown, mouseup, click, focus, and blur events.\
<input type="text" id="zero"/>
<input type="text" id="one"/>
JavaScript:
$(function() {
var one = $('#one');
one.mousedown(function() {
console.log('mousedown');
});
one.mouseup(function() {
console.log('mouseup');
});
one.click(function() {
console.log('click');
});
one.focus(function() {
console.log('focus');
});
one.blur(function() {
console.log('blur');
});
});
If we simply click on the input, and then on another control, we'll get the following:
mousedown
focus
mouseup
click
blur
But if we tab into and out of the input, we'll see in the console:
focus
blur
So, if we keep track of mousedown and blur events, we can tell between a keyboard-based focus and a mouse-based one. For example:
$(function() {
var one = $('#one');
one.mousedown(function() {
console.log('mousedown');
$(this).data('mousedown', true);
});
one.mouseup(function() {
console.log('mouseup');
});
one.click(function() {
console.log('click');
});
one.focus(function() {
if ($(this).data('mousedown')) {
console.log('You clicked it!');
} else {
console.log('You tabbed it!');
}
});
one.blur(function() {
console.log('blur');
$(this).data('mousedown', false);
});
});
A fiddle with this example: http://jsfiddle.net/orlenko/cwRAw/
Use keyup
$('#input').keyup(function(){
alert('Called only when the focus is on element through keypress');
});
function ren(){
alert('Holla!');
}
$('input').focus(ren);
$('input').mousedown(function(){
$('input').off('focus',ren);
});
$('input').mouseup(function(){
$('input').on('focus',ren);
});
Don't check in focus function instead remove the focus function when making a click

Hi is there a way to prevent jquery from detecting a click event when you drag and release outside of an input field?
The thing is I have a modal window that closes when you click outside of the window (the backdrop).
When you have an input field in the modal window and you select the text inside the input and drag your mouse all the way out of the modal window area, then release the click, the modal will close since it detects a click event on that element when it actually wasn't a click event but a "release" event.
Here is an example https://jsfiddle.net/imurphy/tafwzero/1/
Click event code:
$('.how').on('click',function(e){
e.preventDefault();
if(!$(e.target).is('.how')){
return;
}
alert('Modal Closed');
});
Thank you
Check below code.You need use mousedown and mouseup handle the drag and drop
var isDragging = false;
$(".how")
.mousedown(function() {
$(window).mousemove(function() {
isDragging = true;
$(window).unbind("mousemove");
});
})
.mouseup(function() {
var wasDragging = isDragging;
isDragging = false;
$(window).unbind("mousemove");
if (!wasDragging) {
$(this).selection();
}
});
$('.how').on('click',function(e){
e.preventDefault();
if(!$(e.target).is('.how')){
return;
}
alert('Modal Closed');
});
I want to add custom context menu with jQuery for the whole body of the page, except the textfields. How can I do that?
I have tried that code:
$('body:not(input)').bind('contextmenu', function(){
/*code*/
});
Check the srcElement before plugin executions. If it's not an input element, do trigger the contextmenu plugin:
$(document).on("contextmenu", function(e) {
if (!$(e.srcElement).is(":input")) { // if it's not an input element...
$(this).triggerTheContextMenuPlugin();
}
});
Use an event listener on the document and check if it was initiated by an input element.
$(document).on("contextmenu", function (e) {
if (e.target.tagName.toUpperCase() === "INPUT") {
console.log("context menu triggered");
}
});
Demo here
Inspired by Salman's solution.
You can stop the event propagation in all input elements, with the e.stopPropagation() function. In doing so, you keep the default behavior of the inputs elements:
$(function() {
$(document).on("contextmenu", function(e) {
alert("Context menu triggered, preventing default");
e.preventDefault();
});
$("input").on("contextmenu", function(e) {
e.stopPropagation();
});
});
JSFiddle Demo
I want to control events when hovering a <div> element.
I have my code pretty much working, but I have 2 remaining problems!
When I first run the code in my JSFiddle, I need to click on the body of the document first to get the keydown to be recognised. If I run the code and hover right away and press shift nothing happens. I have it running on doc ready,so not sure why I need to click first? Anyway to get this to work right way without needing to click?
I trace out in the console the console.log('click and press'); This is getting fired each time I press shift and is not looking for a click - why is this getting fired when pressing shift when I call it within a function that says $(document).on('keydown click', function (e) {
DEMO
My JS code is as follows
$(document).ready(function () {
$(".target").hover(function () {
$(document).on('keydown click', function (e) {
if (e.shiftKey) {
// code to go here for click
console.log('click and press');
}
});
$(document).on('keydown', function (e) {
if (e.shiftKey) {
// change cursor to ne-resize
$('.target').css('cursor', 'ne-resize', 'important');
}
});
$(document).on('keyup', function (e) {
// change cursor to sw-resize
$('.target').css('cursor', 'sw-resize', 'important');
});
});
});
Thanks
Your event binding is incorrect. you can use:
Demo: http://jsfiddle.net/g9ea8/8/
Code:
$(document).ready(function () {
var hovering = false;
$(".target").hover(function () {
hovering = true;
}, function() {
hovering = false;
});
$(document).on('click', function (e) {
if (hovering && e.shiftKey) {
// code to go here for click
console.log('hovering+shift+click');
}
});
$(document).on('keydown', function (e) {
if (hovering && e.shiftKey) {
// change cursor to ne-resize
$('.target').css('cursor', 'ne-resize', 'important');
console.log('hovering+shift');
}
});
$(document).on('keyup', function (e) {
// change cursor to sw-resize
if(hovering) {
$('.target').css('cursor', 'sw-resize', 'important');
console.log('hovering+keyup');
}
});
});
The reason why you need to click first on the fiddle demo is because the frame doesn't have focus, normally this should work fine.
You shouldn't be attaching a keydown listener, you only need a to attach click, otherwise keydown will fire the event regardless of a click occurring.
Also, currently you're attaching 3 handlers every time you hover over .target, see #techfoobar's answer for a cleaner solution.
looking at this event (being bind on 2 divs overlapping each other, look at the jsfiddle)
.on('contextmenu', function() { ... });
Why do both divs being triggered?
How can I detect this and or stop the underlaying div from triggering?
DEMO: jsfiddle
Thanks for any information!
On nested element, you need to stop event bubbling:
$('#div2').on('contextmenu', function(e) {
e.stopPropagation();
$('#log').append('<p>div2 triggered contextmenu!</p>');
});
DEMO
DEMO
$('#div1,#div2').on('contextmenu', function (e) {
e.stopPropagation();
$('#log').append('<p>' + e.target.id + ' triggered contextmenu!</p>');
});
event.target
event.stopPropagation/
You need to prevent event from propogating, try this code:
$('#div1').on('contextmenu', function(e) {
if(!e.isDefaultPrevented()){
$('#log').append('<p>div1 triggered contextmenu!</p>');
e.preventDefault();
}
});
$('#div2').on('contextmenu', function(e) {
if(!e.isDefaultPrevented()){
$('#log').append('<p>div2 triggered contextmenu!</p>');
e.preventDefault();
}
});
I'm trying to setup an event where it fires after my element is opened. So I have a tooltip and I have a click event which shows the tooltip. Then when that happens I setup a document click event that gets fired so if the user clicks anywhere on the stage it removes all tooltips. But what's happening is it gets called before the tooltip even gets a chance to show. So it's firing the document event over and over again.
$('.container img').popover({placement:'top', trigger:'manual', animation:true})
.click(function(evt){
evt.preventDefault();
el = $(this);
if(el.hasClass('active')){
el.popover('hide');
}else{
clearDocumentEvent();
el.popover('show');
$(document).on('click.tooltip touchstart.tooltip', ':not(.container img)', function(){
hideAllTooltips();
});
}
el.toggleClass('active');
})
var hideAllTooltips = function(){
$('.container img').popover('hide');
$('.container img').removeClass('active');
}
var clearDocumentEvent = function(){
$(document).off('click.tooltip touchstart.tooltip');
};
The problem stems from event bubbling. You can verify this by doing the following test:
$(document).on('click.tooltip touchstart.tooltip', ':not(.container img)', function(){
//hideAllTooltips();
console.log($(this)); // will return .container, body, html
});
Try using event.stopPropogation():
$(document).on('click.tooltip touchstart.tooltip', ':not(.container img)', function(e){
e.stopPropagation();
hideAllTooltips();
});
DEMO:
http://jsfiddle.net/dirtyd77/uPHk6/8/
Side note:
I recommend removing .tooltip from the on function like
$(document).on('click touchstart', ':not(.container img)', function(){
e.stopPropagation();
hideAllTooltips();
});
