I have a code which needs to trigger the input event manually on an input with a datepicker.
The code looks like:
input.on('apply.daterangepicker', function(e) {
input.trigger('input');
});
input.on('input', function(e) {
console.log('11111111111111111111');
});
document.getElementById('filter-created-at').addEventListener('input', function(e) {
console.log('22222222222222222222');
});
The first jQuery event listener works fine. But the second pure JavaScript does not catch the input event. Don't understand it. How can I catch input from trigger() with pure JavaScript addEventListener()?
You can use Element#dispatchEvent to trigger an input event.
document.getElementById('filter-created-at').addEventListener('input', function(e) {
console.log('Regular input');
});
$('#filter-created-at').on('input', function(e) {
console.log('jQuery input');
});
document.getElementById('filter-created-at').dispatchEvent(new Event('input', {
bubbles: true
}))
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id="filter-created-at" />

I need to write an event handler when user clears the text field and moves out of focus from the same.
I'm using the following function to catch "focus out" event.
$("input[type=text]").blur(function () {
}
I have the followingfunction to capture clear field event.
$("input[type=text]").keyup(function() {
if (!this.value) {
}
}
I tried using the keyup() function inside blur() since I need to capture the focus out and then clear field. This is how my code looks like:
$("input[type=text]").blur(function () {
$(this).keyup(function() {
if (!this.value) {
}
}
}
But it doesn't work. Clear field event is triggered even before focus is out of the field. Also, it is triggering the event multiple times. What is the problem here?
I think that is more simple:
$('input').on('blur', function(e) {
if(!$(this).val()) {
// IS NO VALUE IN THE INPUT
$(this).trigger('blur'); // trigger the blur event
}
});
Here you are:
$("input[type=text]").on('blur', function() {
alert('blur');
});
$("input[type=text]").on('input', function() {
if (!$(this).val()) {
alert("input nothing");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" />
Hope this helps.
I want to detect a change in the input field when i select a value from the box like in the picture below.
html:
<input type="text" class="AgeChangeInput" id="range"/>
js:(not working)
<script>
$(document).ready(function()
{
alert("Hello");
$("#range").bind('input', function()
{
alert("done");
});
});
</script>
I also tried live on functions but they didn;t work too.
Your date selection box should fire a change event, then you only need to capture it:
$(function () {
$('#range').change(function () {
...
});
});
If the selection box doesn't fire the event, you'll need to trick the dom. Something like:
$(document).ready(function () {
// Asuming your selection box opens on input click
$('#range').click(function () {
$('.special-box-class').click(fireRangeEvent);
});
// Now the firing function
function fireRangeEvent() {
...
}
});
Hope it works
Try to use this code
changeDate - This event is fired when the date is changed.
$('#range').datepicker().on('changeDate', function(ev) {
//example of condition
if (ev.date.valueOf() > checkout.date.valueOf()) {
//make action here
alert('Here');
}
});
focusout on input field will trigger every time the specific input looses its focus.
But, I want to exclude some specific a tag from triggering that focusout function
Example:
<input type="text" id="name_input">
<a id="apply_name">SAVE</a>
Then the focusout function:
$("#name_input").focusout(function(e) {
//do something here
});
Clicking on "#apply_name" also triggers focusout function of an input. How can I exclude that specific element ID from triggering it.
Note: I tried some tricks already posted on StackOverflow and none of them seams to work...
Another way of doing this is checking what your target id is
var evt;
document.onmousemove = function (e) {
e = e || window.event;
evt = e;
}
$("#name_input").focusout(function (e) {
if (evt.target.id == "apply_name") {
//apply_name clicked
} else {
//focus out and applyname not clicked
}
});
DEMO
You can use "blur" - event.
$("#name_input").on("blur", function(e) {
//your code
});
Solution from How to exclude Id from focusout
Added .hasClass which I also needed:
$('#id').focusout (function (e) {
if (e.relatedTarget && $(e.relatedTarget).hasClass('dontFocusOut')) {
return;
}
//do your thing
});
In the following example, there is a simple input field and a button.
<body>
<input type="text" id="in">
<input type="button" value="click" id="button">
</body>
There is a change-event-function on the input field and a click-event-function on the button.
$(document).ready(function() {
$('#in').change(function() {
console.log('change event');
//window.alert('change event');
});
$('#button').click(function() {
console.log('click event');
});
});
On changing the value of the input field and immediately clicking the button (without leaving the cursor), my expectation is, that both events are fired. Unfortunately this behavior depends on the code executed inside the change-function e.g. on uncommenting the window.alert line, the click event is NOT fired - or the click-event-function is not executed. Why? How can I avoid code, which prevents the click-event-function from executing?
Update:
instead of the window.alert, the jquery.hide has the same effect
$(document).ready(function() {
$('#in').change(function() {
console.log('change event');
$('#hide').hide();
});
$('#button').click(function() {
console.log('click event');
});
});
If you want to fire both of two events, you can do like this:
$(document).ready(function() {
$('#in').change(function() {
console.log('change event');
window.alert('change event');
$('#button').click();
});
$('#button').click(function() {
console.log('click event');
});
});
Try
$(document).mousedown(function(e){
console.log('click event');
});
The mousedown event will occur before textbox change and click events so that you need to set time out and check the changed value of the text box if required.
I am trying to trigger the change() function of my form manually with jQuery 1.7.2, but it doesn't work. This is my code:
$(document).ready(function(){
console.log('going to change form');
$('form[name="newBom"] input').trigger('change');
$('form[name="newBom"] input').change(function() {
console.log('form changed');
});
});
What am I doing wrong?
You are not getting the expected functionality as you are triggering the change even before a change handler is bound to your input(s). You can correct this by triggering the change event after binding the change handler:
// bind the handler
$('form[name="newBom"] input').change(function() {
console.log('form changed');
});
// now, trigger the change event
$('form[name="newBom"] input').trigger('change');
$(document).ready(function(){
console.log('going to change form');
//Attach event handler first
$('form[name="newBom"] input').change(function() {
console.log('form changed');
}); // missing );
//Trigger event
$('form[name="newBom"] input').trigger('change');
}); //missing );
