The Jquery Focus is not working for a single input button click is working only problem is with the input field as shown in the below code:
Not working only for single input field.
$(document).ready(function(){
$("#val").change(function(){
$("input").focus();
$("p").html("focus event triggered");
});
$("#btn1").click(function(){
$("input").focus();
$("p").html("focus event triggered");
});
$("#btn2").click(function(){
$("input").blur();
$("p").html("blur event triggered");
});
});

If what you want to achieve is to retain focus even on clicking tab then you will have to use keydown() instead of change().
Actually your code is working fine. Only that the change() is not triggered the second time you press tab without changing the input.
$(document).ready(function(){
$("#val").keydown(function(e){
if(e.which == 9) {
e.preventDefault();
$("p").html("focus event triggered");
}
});
$("#btn1").click(function(){
$("#val").focus();
$("p").html("focus event triggered");
});
$("#btn2").click(function(){
$("input").blur();
$("p").html("blur event triggered");
});
});
I have added the jsfiddle link below : Keydown Example
$(document).ready(function(){
$("#val").on('input', function(){
$("input").focus();
$("p").html("focus event triggered");
});
$("#btn1").click(function(){
$("input").focus();
$("p").html("focus event triggered");
});
$("#btn2").click(function(){
$("input").blur();
$("p").html("blur event triggered");
});
});
i think what you're trying to do is to trigger change event when input value changed
If i understand you're question correct you just have to change the change function to the blur function in your javascript function.
This will trigger the focus on the input element.
$(document).ready(function(){
$("#val").on('blur', function(e){
$("input").focus();
$("p").html("focus event triggered");
});
$("#btn1").click(function(){
$("input").focus();
$("p").html("focus event triggered");
});
$("#btn2").click(function(){
$("input").blur();
$("p").html("blur event triggered");
});
});

I have a text-field whose value will be set on the click of a button. I want to detect when the value of the input field will change. I can't figure out the specific event to fire.
<!DOCTYPE html>
<html>
<head>
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
function myFunction() {
$('#mytxtBox').val("2018/12/18");
}
$(document).on('input', '#mytxtBox', function() {
alert("Eureka!!!")
});
</script>
</head>
<body>
<input id='mytxtBox' type="text">
<button onclick="myFunction()">Press it</button>
</body>
</html>
Use trigger method to trigger the input event.
$('#mytxtBox').val("2018/12/18").trigger("input");
You need the change event. first you subscribe the input to the event listener, and add your logic that you want to fire when the event is called. Then you trigger the event after an update. Something like...
$(function(){//bind the event listener
$('#mytxtBox').on('change', function(){
//do stuff here
});
})
function myFunction() {
$('#mytxtBox').val("2018/12/18");
$('#mytxtBox').trigger('change');//trigger the event
}
Just assign the change a .change() and it will trigger the onChange event
$('#updateValue').on('click', function () {
$('#mytxtBox').val("2018/12/18").change();
});
$('#mytxtBox').on('change', function() {
console.log('abc');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id='mytxtBox' type="text">
<button id="updateValue"> Press it </button>
Try this..
the alert will pop before the value appear
<!DOCTYPE html>
<html>
<head>
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
function myFunction() {
$('#mytxtBox').val("2018/12/18").trigger("eureka");
}
$(function(){
$('#mytxtBox').on("eureka", function() {
alert("Eureka!!!")
});
});
</script>
</head>
<body>
<input id='mytxtBox' type="text">
<button onclick="myFunction()">Press it</button>
</body>
</html>
We can try using passing function as a callback to val() method.
Reference: http://api.jquery.com/val/#val-function
function myFunction() {
$('#mytxtBox').val(function(i ,value){
alert('hello i am going to change');
return "2018/12/18";
});
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id='mytxtBox' type="text">
<button onclick="myFunction()">Press it</button>
There are multiple events for textbox such as keypress, change, keydown, keyup etc. You can select any as suitable for your goal.
Below example use keypress event:
function fnChangedText() {
alert("Eureka!!!");
}
function myFunction() {
$('#mytxtBox').val("2018/12/18");
$('#mytxtBox').keypress();
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id='mytxtBox' type="text" onkeypress="fnChangedText()">
<button onclick="myFunction()"> Press it </button>
Using jquery can click based on class and id attributes but can click be invoked based on ref attribute ?
I've based below code on ref="btFirst", but unsure how to access ref.
JSFiddle src:
<button class="ag-paging-button" onclick="alert('Hello world!')" ref="btFirst" data-vivaldi-spatnav-clickable="1">First</button>
$( ".btFirst" ).click(function() {
alert( "Handler for .click() called." );
});
Use CSS attribute selector (nice and thorough CSS Tricks reference):
$('[ref="btFirst"]').on("click", function(e) {
alert( "Handler for .click() called." );
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button ref="btFirst">Click me</button>
You can use
$('button[ref="btFirst"]').on('click', function(e){
alert('ref button clicked');
});
$('button[ref="btFirst"]').on('click', function(e){
alert('ref button clicked');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<button class="ag-paging-button" onclick="alert('Hello world!')" ref="btFirst" data-vivaldi-spatnav-clickable="1">First</button>
If you want to be more specific:
Html:
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<button class="ag-paging-button" ref="btFirst" data-vivaldi-spatnav-clickable="1">First</button>
</body>
</html>
jQuery:
$(document).ready(function(){
$( "button.ag-paging-button[ref='btFirst']" ).on('click', function() {
alert( "Handler for .click() called." );
});
});
You dont need to add onclick="alert('Hello world!')" in button tag
Hope this may help you.
I'm writing a Javascript script tightly bounded to events. I must execute some instructions on 'focus' event, and some different instructions on 'select' event.
With my surprise I see that giving focus programmatically, fires 'select' event too! That's a big problem.
Can you tell me why this is happening, and if I can block select event programmatically only when I give focus programmatically?
See the following example. When clicking to 'Give focus' button, console will write 'You selected something'!
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
</head>
<body>
<input id="field" type="text" />
Give focus
<script>
$(document).ready(function () {
$('#field').on('select', function(e) {
console.log('You selected something');
});
$('#btn').on('click', function(e) {
$('#field').focus();
})
});
</script>
</body>
</html>
Try this:
$(document).ready(function () {
$('#field').on('select', function(e) {
console.log('You selected something');
});
$('#btn').click( function(e) {
$('#field').focus();
})
});
<input id="field" type="text" />
Give focus

I'm trying to use sth like onchange but with no results.
i've been searching for a while but i didn't find.
HTML
<input type="text" id="myInput" />
<div id="button"></div>
JS
<script>
$("#button").on('click', function()
{
$("#myInput").val("new value");
});
$("#myInput").on('change keyup paste blur oncut propertychange', function()
{
//my code
});
</script>
I can't find a event where a JQ action is recognized like a changing in my input...
Thank you for your help!
Did you put these js code part into the $(document).ready(function(){
});
I think because these js is not loaded when the webpage is completed loaded.
$(document).ready(function(){
$("#button").on('click', function()
{
$("#myInput").val("new value");
});
$("#myInput").on('change keyup paste blur oncut propertychange', function()
{
console.log('event detected');
});
});

})
$('input').click(function(){
alert('gggg')
})
</script>
and when i click the button, it alert twitce,
so how to Cover the first Statement ,
thanks
Remove this from the <script> block
$('input').click(function(){
alert('sss')
})
so that you are left with only
<input type="button" value="edit" id="edit"/>
<script type="text/javascript" src="jquery-1.4.2.js"></script>
<script type="text/javascript">
$('input').click(function(){
alert('gggg');
});
</script>
You could use jQuery.unbind() method to remove any click event listener from specified elements and then bind a new one:
$("input").unbind("click").click(function() {
alert("This is the only listener bound to this element");
});
$('input').click(function(){
alert('gggg') ;
return false;
})
or
$('input').click(function(event){
alert('gggg') ;
event.stopPropagation();
})
Now to completely get rid of that event handler, you could unbind it:
$('input').click(function(){
alert('sss')
});
// :
// :
$('input').unbind("click");
$('input').click(function(){
alert('gggg')
})
