This script has been added dynamically. It has a timeout function, means that it runs every 5 seconds.
dynamicjs.php
$(document).ready(function(){
(function( $ ){
$.fn.baslatmesajlari = function() {
setInterval(function(){
console.log("I am running");
}, 5000);
return this;
};
})( jQuery );
});
$("body").baslatmesajlari();
I load this function to a div using;
$("#temporarycontent").load("dynamicjs.php");
And when I do
$("#temporarycontent").empty();
The script is still running. How can I stop it run ?
You can't, you need a handle to the intervalId returned by the setInterval function or provide an API on the plugin in order to destroy it and cleanup after itself. The easiest way would be to attach the state of the plugin to the DOM element on which it was applied.
(function ($) {
const PLUGIN_NAME = 'baslatmesajlari';
function Plugin($el) {
this.$el = $el;
this._timerId = setInterval(function () {
console.log('running');
}, 2000);
}
Plugin.prototype.destroy = function () {
this.$el.removeData(PLUGIN_NAME);
clearInterval(this._timerId);
};
$.fn[PLUGIN_NAME] = function () {
if (!this.data(PLUGIN_NAME)) this.data(PLUGIN_NAME, new Plugin(this));
return this;
};
})(jQuery);
$(function () {
var plugin = $('#plugin').baslatmesajlari().data('baslatmesajlari');
$('#destroy').click(function () {
plugin.destroy();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="plugin"></div>
<button id="destroy">Destroy plugin</button>
You must have a reference to the interval id, then, when you want to stop it's execution, call clearInterval(the_id)
let interval = null //this is the variable which will hold the setInterval id
$(document).ready(function () {
(function ($) {
$.fn.baslatmesajlari = function() {
interval = setInterval(function () {
console.log('I am running')
}, 5000)
return this
}
})(jQuery)
})
$("body").baslatmesajlari()
And then:
$("#temporarycontent").empty();
clearInterval(interval) // it should stop the function.
Hope it helps.

I have a lot of input fields with the same class. When the user finishes typing the function doneTyping should run.
I tried this but somehow it doesn't work.
Can I use one function for all the input fields I have?
$(function() {
console.log('ready');
var timer;
var doneTypingInt = 5000;
$('.typing').keyup(function(){
clearTimeout(timer);
if ($('.typing').val()) {
timer = setTimeout(doneTyping, doneTypingInt);
}
});
function doneTyping () {
console.log('function doneTyping');
}
});
what you're looking for is debounce
$('.typing').keypress(_.debounce(yourfunc, 3000))
You basically want to use the keypress function. Your adjusted code:
$(function() {
console.log('ready');
var timer;
var doneTypingInt = 5000;
$('.typing').keypress(function(event){
if(timer) {
clearTimeout(timer);
timer = null;
}
timer = setTimeout(doneTyping, doneTypingInt);
});
function doneTyping () {
console.log('function doneTyping');
}
});
I don't think that you have something wrong in your code, you just have to wait 5 seconds to see the result, and in order to use one function for all inputs with the "typing" class, you should use the bind method as follows:
Javascript code: (Jsfiddle)
$(function() {
console.log('ready');
var timer;
var doneTypingInt = 1000;
$('.typing').keyup(function(){
clearTimeout(timer);
if ($('.typing').val()) {
timer = setTimeout(doneTyping.bind($(this)), doneTypingInt);
}
});
function doneTyping () {
alert('function doneTyping ' + this.val());
}
});
I have a custom jQuery function. When it runs every 5 seconds.
(function($) {
$.fn.mycustomfunction = function() {
interval = setInterval(function() {
console.log("I am running every 5 seconds");
}, 5000);
}
return this;
};
})(jQuery);
$("#container").mycustomfunction();
I have a
clearInterval(interval);
to stop, but I also want to stop the function completely. How can I do that ?
Functions you add to this object will be attached to your object and Simple and naive solution will follow:
(function($) {
$.fn.mycustomfunction = function() {
interval = setInterval(function() {
console.log("I am running every 5 seconds");
}, 1000);
this.stop= function(){
clearInterval(interval);
}
// another function
this.alert = function(msg){
alert(msg)
}
return this;
};
})(jQuery);
to stop use
var feature = $("#container").mycustomfunction();
feature.stop();
I'm new to jQuery and I need a bit of help. I'm using this jQuery script as a testimonial rotator and it works like a charm but I just need to make one small tweak. I need it to be able to pause on hover and then restart when the mouse leaves the div. How can I do this?
This is the script I'm using:
function fadeMyContent() {
$(".testimonial:first").fadeIn(1000).delay(3000).fadeOut(1000,
function() {
$(this).appendTo($(this).parent());
fadeMyContent();
});
}
fadeMyContent();
});
Here is a JSFiddle.
There is a plugin that will provide all the functionality you need and be more reliable called jQuery Cycle 2.
It provides a 'pause-on-hover' option when initialising it.
change the definition of fadeMyContent (also called as destroying function) on hovering on ul#testimonial-rotator and on hover-out change it to old definition again. I have used setTimeout in place of delay because delay is not cancellable.
$(document).ready(function () {
var fadeMyContent;
var t
fadeMyContent = function () {
$(".rotate:first").fadeIn(1000)
t = setTimeout(function () {
$(".rotate:first").fadeOut(1000,
function () {
$(this).appendTo($(this).parent());
fadeMyContent();
});
}, 3000)
}
var fadeMyContentDummy = function () {
$(".rotate:first").fadeOut(1000,
function () {
$(this).appendTo($(this).parent());
fadeMyContent()
});
}
fadeMyContent();
$('#testimonial-rotator').hover(function (e)
{
window.clearTimeout(t)
$('.rotate:first').clearQueue()
fadeMyContent = function () {
return false;
}
},
function (e)
{
fadeMyContent = function () {
$(".rotate:first").fadeIn(1000)
t = setTimeout(function () {
$(".rotate:first").fadeOut(1000,
function () {
$(this).appendTo($(this).parent());
fadeMyContent();
});
}, 3000)
}
fadeMyContentDummy()
})
});

I would like to have an animation funciton show for 2 seconds once the submit button is clicked. I am not sure how to put it all together using the setTimeout function
$(window).ready(function () {
"use strict";
var countdown = 2000;
setTimeout(function()){
var startAnimation = function () {//this is what I need to animate for 2 seconds
$(".normal-actions").hide();
$(".execute-actions").show();
};
$("form").attr("action", "url");
$(".btn-submit").on("click", function () {
$("form").submit;
});
});
}
current code (could not put in comments) the page stays in loading and does not redirect:
$(window).ready(function () {
"use strict";
var countDown = 2000;
setTimeout(function(){
$(".normal-actions").hide();
$(".execute-actions").show();
}, countDown);
$("form").attr("action", "url");
$(".btn-submit").on("click", function () {
$("form").submit;
});
});
You never actually called setTimeout and never made an initial change to the UI. You should call it when submit is clicked.
$(window).ready(function () {
"use strict";
var countdown = 2000;
var toggleAnimation = function () {//this is what I need to animate for 2 seconds
$(".normal-actions").toggle(); //toggles between show/hide
$(".execute-actions").toggle();
};
$("form").attr("action", "url");
$(".btn-submit").on("click", function () {
$("form").submit;
toggleAnimation(); //first call start animation to change the UI
setTimeout(toggleAnimation, countdown); //then call startAnimation again after 2 seconds to change it back
});
});
}
$(window).ready(function () {
"use strict";
var countdown = 2000;
$("form").attr("action", "url");
$(".btn-submit").on("click", function () {
//When the button is clicked change class to indicate that the process started
$(".normal-actions").hide();
$(".execute-actions").show();
$("form").submit;
//2 seconds later revert the changes in the classes
setTimeout(function() {
$(".normal-actions").show();
$(".execute-actions").hide();
}, 2000);
});
}
//
// give this a go:
//
function wait( function_, time_out_in_ms ) {
return function () {
var args = Array.prototype.slice.call( arguments ),
target = this;
setTimeout(
function () {
return function_.apply( target, args );
},
time_out_in_ms
);
return this;
};
}
//
// use:
//
var
fn1 = wait(
function () { console.log( this, arguments ); },
3000
);
fn1.call( document, { info : "stuff" } );
fn1(1,2);
//
//
// Document & Window <-- returned imidiately
//
// ... logged after 3 sec:
// Document [Object { info="stuff"}]
// Window [1, 2]
//
Set your animation as the function callback to setTimeout():
setTimeout(function(){
$(".normal-actions").hide();
$(".execute-actions").show();
}, countDown);
Or if you want to reuse your function:
var startAnimation = function () {
$(".normal-actions").hide();
$(".execute-actions").show();
};
setTimeout(startAnimation, countDown);
EDIT: Your form is not submitting because you are not evoking the submit function:
$(".btn-submit").on("click", function () {
$("form").submit(); // <-- open and closed paren
});
I have the following code partially working. I am newbie in javascript so please don't blame me if my approach is not the best.
window.url_var = "status.htm";
window.elem = "#e1";
function menu_item(){
$(window.elem).click(function (event)
{
$("#divTestArea1").load(window.url_var);
});
}
$("#e1").click(function (event)
{
event.preventDefault();
window.url_var = "demo2.txt";
window.elem = "#e1";
$("#divTestArea1").load(window.url_var);
auto_refresh = setInterval(menu_item(), 5000);
});
$("#e2").click(function (event)
{
event.preventDefault();
window.url_var = "status.htm";
window.elem = "#e2";
$("#divTestArea1").load(window.url_var);
auto_refresh = setInterval(menu_item(), 5000);
});
$("#e3").click(function (event)
{
event.preventDefault();
window.url_var = "form.htm";
window.elem = "#e3";
clearInterval(auto_refresh);
$("#divTestArea1").load(window.url_var);
});
jQuery(document).ready(function() {
$("#divTestArea1").load(window.url_var);
auto_refresh = setInterval(menu_item(), 5000);
});
Whenever I click elements e1 and e2, the setInterval works as expected and as soon as I click element e3, the element cease to be reloaded.
That's the behavior I want so far. But I also wants to start the setinterval again if e1 or e2 get's again clicked.
the last is what it's not working on the above code.
I will appreciate if you could point me in the right direction.
I have come to this code after seeing some of the answers to my original question (thanks to everyone). To clarify my original idea, I need to update some items on my web page on a regular basics but the content can be change with some menu and also some of the contents like a form should not be updated.
window.url_var = "demo2.txt";
var auto_refresh = null;
function setRefresh() {
var self = this;
this.bar = function() {
if(window.url_var != ""){
$("#divTestArea1").load(window.url_var);
auto_refresh = setTimeout(function() { self.bar(); }, 5000);
}
}
this.bar();
}
$("#e1").click(function (event)
{
event.preventDefault();
window.url_var = "demo2.txt";
setRefresh();
});
$("#e2").click(function (event)
{
event.preventDefault();
window.url_var = "status.htm";
setRefresh();
});
$("#e3").click(function (event)
{
event.preventDefault();
window.url_var = "form.htm";
$("#divTestArea1").load(window.url_var);
window.url_var = "";
});
$(document).ready(function() {
setRefresh();
});
Try using 2 different variables and clearing all if needed. This is: auto_refresh1 and auto_refresh2. Each time you call setinterval, it creates a new timer with a new id. You are overwriting auto_refresh variable and the timer before that will still fire.
Or you can store the setinterval in a hash object and run through and clear them all.
I'm unclear as to what exactly it is that you're trying to do here. Nevertheless, I've rewritten your code a bit to make some improvements (and fix one glaring bug in your code involving the setInterval calls).
var url_var = "status.htm",
elem = "#e1",
$destination = $("#divTestArea1"),
auto_refresh;
function menu_item() {
$(elem).bind("click", function (e) {
$destination.load(url_var);
});
}
function load() {
$destination.load(url_var);
}
function set(url, id) {
url_var = url;
elem = id;
}
function setRefresh() {
return setInterval(menu_item, 5000);
}
function handleClick(e) {
e.preventDefault();
set(e.data.url, e.data.id);
load();
auto_refresh = setRefresh();
}
$("#e1").on("click", {
url: "demo2.txt",
id: "#e1"
}, handleClick);
$("#e2").on("click", {
url: "status.htm",
id: "#e2"
}, handleClick);
$("#e3").on("click", function (e) {
e.preventDefault();
set("form.htm", "#e3");
clearInterval(auto_refresh);
load();
});
$(document).ready(function () {
load();
auto_refresh = setRefresh();
});
I'm guessing that maybe those setInterval calls should actually be setTimeout calls? Why would you want to bind a "click" event handler over and over again?
EDIT #1: Switched to jQuery's currently preferred on method from the bind method, included use of event data parameter to further abstract event handling code.
