I have below jquery code which is execute on keypress but I would like to execute same on button click. Please help me.
$('#itemselected').live('keypress', function() {
//some code which using $(this) also.
}
var myFunction = function(event){
console.debug(event);
//do your stuff here
};
$('#itemselected').on('keypress', function(event) {
myFunction(event);
}
$('#itemselected').on('click', function(event) {
myFunction(event);
}
Try to trigger the keypress on click
$('button').click(function() {
$('#itemselected').trigger('keypress');
});
I think you can just add 'click' to the list of event types like so:
$('#itemselected').on('keypress click', function() {
//some code which using $(this) also.
});

Why doesn't the on click listener work after clicking on the first list-button?
JSFiddle link
$(".acceptTask").on("click", function(){
acceptTask(this);
});
$(".solveTask").on("click", function() {
solveTask(this);
});
function solveTask(e){
...
}
function acceptTask(e){
...
$(document).on("click", ".solveTask", solveTask);
}
$('.solveTask').on('click', /*...*/) only applies the event handler to anything that has a class "solveTask" at that time. So when you add the solveTask class in your acceptTask function, add an event listener.
$(e).addClass('btn-warning solveTask')
.click(function () { solveTask(this); });
See fiddle: https://jsfiddle.net/1203y34b/1/
I had this problem previously and used 'delegate' instead of 'on':
$(document).delegate('.solveTask', 'click', solveTask)
I have a button that can be in 2 different states (lets say Lock and Unlock). When I click on the button, I update the class on the button to reflect the binary opposite state. Each class has a different event attachment function using on(string, callback). For some reason the event being triggered remains the first callback assigned based on the original class.
HTML:
<button class="lock">Lock</button>
<button class="unlock">Unlock</button>
JavaScript:
$(document).ready(function() {
$('.lock').on('click', function() {
// Perform some magic here
console.log('Lock!');
$(this).removeClass('lock')
.addClass('unlock')
.html('Unlock');
});
$('.unlock').on('click', function() {
// Perform some magic here
console.log('Unlock!');
$(this).removeClass('unlock')
.addClass('lock')
.html('Lock');
});
});
https://jsfiddle.net/c283uaog/ for testing.
Expected console output when clicking on the same button repeatedly:
Lock!
Unlock!
Lock!
Actual console output:
Lock!
Lock!
Lock!
Any assistance would be greatly desired
use event Delegation
$(document).on('click','.lock', function() {
$(document).on('click','.unlock', function() {
updated Demo
Or use in single function with toggleClass
$(document).on('click', '.lock,.unlock', function () {
$('#output').html($(this).attr('class'));
$(this).toggleClass('lock unlock').text($(this).attr('class'));
});
ToggleClass demo
I'd do it this way, attaching only one event: http://jsfiddle.net/jozu47tv/
$(".lock").on('click', function(e) {
e.preventDefault();
if($(this).hasClass("lock")) {
$(this).removeClass("lock").addClass("unlock");
console.log("lock -> unlock");
} else {
$(this).removeClass("unlock").addClass("lock");
console.log("unlock -> lock");
}
})
Use Event Delegation method, Try this updated fiddle,
$(document).ready(function() {
$(document).on('click', '.lock', function() {
$('#output').html('Lock!');
$(this).removeClass('lock')
.addClass('unlock')
.html('Unlock');
});
$(document).on('click', '.unlock', function() {
$('#output').html('Unlock!');
$(this).removeClass('unlock')
.addClass('lock')
.html('Lock');
});
});
Probably, this question could answer you in a better way:
jQuery .on function for future elements, as .live is deprecated
$(document).on(event, selector, handler)
Change your html to this:
<button class="locker lock" >Lock</button>
<button class="locker unlock"">Unlock</button>
<div id="output">Output</div>
and your Js to this:
$(document).ready(function() {
$('.locker').on('click', function() {
if($(this).hasClass("lock")){
$(this).removeClass("lock");
$(this).addClass("unlock");
$(this).html("unlock");
}
else if($(this).hasClass("unlock")){
$(this).removeClass("unlock");
$(this).addClass("lock");
$(this).html("lock");
}
});
});
Suppose I want to run a function myFunction at each of the events $(document).ready, $(sometag).on('click',....). How can I construct a function that checks if any of those two events are triggered, and then run the method. Can I pass $(document) as an argument and then check $(document).isReady or check $(document).click(function(e){if (e.target.is($(some tag))) ...}). Is this correct ?
It's not easy to understand what the heck you are talking about, but it sounds like you're trying to attach an event handler and trigger it on document ready, and if so you'd do that like this :
$(document).ready(function() {
$(sometag).on('click', function() {
// do stuff
}).trigger('click');
});
If I understand you correctly:
function myFunc(event) {
if (event.type == 'ready')
console.log('It is a document.ready');
else if (event.type == 'click')
console.log('It is a click');
}
$(document).on('ready', myFunc).on('click', 'a', myFunc);
jsfiddle
from what i could understand from your question...
Jsfiddle: http://jsfiddle.net/patelmilanb1/eR4wG/1/
$('.checkbox').change(function (e) {
if (e.isTrigger) {
alert('not a human');
} else {
alert("manual check by human");
}
});
$('.checkbox').trigger('change'); //alert not a human because it is automatically triggered.
I may not understand your question very much, but try this:
$(function(){
$('div1,div2,#id1,#id2,.class1,.class2').click(function(){
// do something
yourFunction();
});
});
triggering function on multiple events of an element, you may try:
$('#element').on('keyup keypress blur change', function() {
...
});
and multiple function on multiple elements, try:
$('#element #element1 #element2').on('keyup keypress blur change', function() {
...
});
I have one html div on my jsp page, on that i have put one anchor tag, please find code below for that,
<div class="expandable-panel-heading">
<h2>
<a id="ancherComplaint" href="#addComplaint"
onclick="markActiveLink(this);">ABC</a>
</h2>
</div>
js code
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
alert('123');
});
function markActiveLink(el) {
alert($(el).attr("id"));
}
here I when I click on div I got alert with 123 message, its fine but when I click on ABC I want message I want to call markActiveLink method.
JSFiddle
what is wrong with my code? please help me out.
The problem was that clicking the anchor still triggered a click in your <div>. That's called "event bubbling".
In fact, there are multiple solutions:
Checking in the DIV click event handler whether the actual target element was the anchor
→ jsFiddle
$('.expandable-panel-heading').click(function (evt) {
if (evt.target.tagName != "A") {
alert('123');
}
// Also possible if conditions:
// - evt.target.id != "ancherComplaint"
// - !$(evt.target).is("#ancherComplaint")
});
$("#ancherComplaint").click(function () {
alert($(this).attr("id"));
});
Stopping the event propagation from the anchor click listener
→ jsFiddle
$("#ancherComplaint").click(function (evt) {
evt.stopPropagation();
alert($(this).attr("id"));
});
As you may have noticed, I have removed the following selector part from my examples:
:not(#ancherComplaint)
This was unnecessary because there is no element with the class .expandable-panel-heading which also have #ancherComplaint as its ID.
I assume that you wanted to suppress the event for the anchor. That cannot work in that manner because both selectors (yours and mine) select the exact same DIV. The selector has no influence on the listener when it is called; it only sets the list of elements to which the listeners should be registered. Since this list is the same in both versions, there exists no difference.
Try this
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
alert('123');
});
$('#ancherComplaint').click(function (event) {
alert($(this).attr("id"));
event.stopPropagation()
})
DEMO
Try following :
$('.expandable-panel-heading').click(function (e) {
if(e.target.nodeName == 'A'){
markActiveLink(e.target)
return;
}else{
alert('123');
}
});
function markActiveLink(el) {
alert($(el).attr("id"));
}
Here is the working demo : http://jsfiddle.net/JVrNc/4/
Change your jQuery code with this. It will alert the id of the a.
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
markActiveLink();
alert('123');
});
function markActiveLink(el) {
var el = $('a').attr("id")
alert(el);
}
Demo
You need to read up on event bubbling and for sure remove inline event handling if you have jQuery anyway
Test the click on the div and examine the target
Live Demo
$(".expandable-panel-heading").on("click",function (e) {
if (e.target.id =="ancherComplaint") { // or test the tag
e.preventDefault(); // or e.stopPropagation()
markActiveLink(e.target);
}
else alert('123');
});
function markActiveLink(el) {
alert(el.id);
}
I would have used stopPropagation like this:
$('.expandable-panel-heading:not(#ancherComplaint)').click(function () {
alert('123');
});
$('#ancherComplaint').on('click',function(e){
e.stopPropagation();
alert('hiiiiiiiiii');
});
Try out this example, the onclick is still called from your HTML, and event bubbling is stopped.
<div class="expandable-panel-heading">
<h2>
<a id="ancherComplaint" href="#addComplaint" onclick="markActiveLink(this);event.stopPropagation();">ABC</a>
</h2>
</div>
http://jsfiddle.net/NXML7/1/
put your jquery function inside ready function for call click event:
$(document).ready(function() {
$("#ancherComplaint").click(function () {
alert($(this).attr("id"));
});
});
when click on div alert key
$(document).delegate(".searchbtn", "click", function() {
var key=$.trim($('#txtkey').val());
alert(key);
});
How would I make sure that this href element is will fire "click" event unless it does NOT have "disablelink" class.
DO NOT PROCESS:
<a class="iconGear download disablelink" href="#">Download</a>
PROCESS:
<a class="iconGear download" href="#">Download</a>
tried this without success:
$("a.download").not(".disablelink").click(function (e) {
alert('in');
e.preventDefault();
});
This should work:
$("a.download:not('.disablelink')").click(function (e) {
alert('in');
e.preventDefault();
});
If the disablelink class is being added dynamically:
$(document).on('click', "a.download:not('.disablelink')", function (e) {
alert('in');
e.preventDefault();
});
Check this demo: http://jsfiddle.net/d3rXr/1/
$('a.download').click(function(e){
e.preventDefault();
if($(this).hasClass('disablelink')){
return;
}else{
//other stuff;
}
});
Why don't you check when the anchor is clicked, and if it has the class it returns and does nothing, which would be more readable code I guess.
You could go like this:
$("a.download").click(function(e) {
if($(this).hasClass("disablelink")) {
return false;
}
// Normal code
alert('in');
e.preventDefault();
});
Firstly, this probably doesn't work because some links had disablelink added to them dynamically, and after they already had the click handler bound to them.
Secondly, you should just check for that class inside the click handler, like so:
$("a.download").click(function (e) {
if($(this).hasClass('disablelink')){
e.preventDefault();
// link is disabled
}else{
alert('in');
// link is active
}
});
