Let me explain what the trouble is. I have two functions: compute(); and discount_compute();. When the page firsts load both functions get executed once (OK, since discount_compute() is part of compute so it always runs when compute() is executing). When I open the #autobid-panel (it is set on display:none initially) the function discount_compute runs 1 time because of the $('#autobid').on('click', function(), but then it also runs 2 more times because of the '[data-slider]').on('change.fndtn.slider'). Btw everytime this autobid-panel is closed or opened the slider is initialized again. I only want the discount_compute() to run once when #autobid-panel is opened. Any ideas?
function compute() {
//first function
};
function discount_compute() {
//second function
};
$(document).ready(function($) {
$('.price').change(compute).change();
$('#autobid').on('click', function() {
if ($(this).is(':checked')) {
$('#autobid-panel').removeClass("hide");
$(document).foundation('slider', 'reflow');
discount_compute();
} else {
$('#autobid-panel').addClass("hide");
$(document).foundation('slider', 'reflow');
}
});
$('#discount').on('change', function(){
var value = $(this).val();
$('.range-slider').foundation('slider', 'set_value', value);
discount_compute();
});
$('[data-slider]').on('change.fndtn.slider', function(){
discount_compute();
});
});
Thank your for your help!
You don't really explain the reasoning of the data-slider or why you even call discount_compute(); there if you don't want to run it.
One dirty hack you can do is something to this effect:
function compute() {
//first function
};
function discount_compute() {
//second function
};
var harRun=false;
$(document).ready(function($) {
$('.price').change(compute).change();
$('#autobid').on('click', function() {
if ($(this).is(':checked')) {
$('#autobid-panel').removeClass("hide");
$(document).foundation('slider', 'reflow');
if(hasRun != true) {discount_compute(); hasRun=true;}
} else {
$('#autobid-panel').addClass("hide");
$(document).foundation('slider', 'reflow');
}
});
$('#discount').on('change', function(){
var value = $(this).val();
$('.range-slider').foundation('slider', 'set_value', value);
discount_compute();
});
$('[data-slider]').on('change.fndtn.slider', function(){
if(hasRun != true) {discount_compute();}
});
});
In this way, once hasRun is set to true you no longer call discount_compute().
unfortunately $(document).foundation('slider', 'reflow'); fires a change event, so there isn't any nice way.
one way is to off the event before reflow and on straight after:-
function compute() {
//first function
};
function discount_compute() {
//second function
};
$(document).ready(function($) {
$('.price').change(compute).change();
$('#autobid').on('click', function() {
if ($(this).is(':checked')) {
$('#autobid-panel').removeClass("hide");
$('[data-slider]').off('change.fndtn.slider', discount_compute);
$(document).foundation('slider', 'reflow');
$('[data-slider]').on('change.fndtn.slider', discount_compute);
discount_compute();
} else {
$('#autobid-panel').addClass("hide");
$(document).foundation('slider', 'reflow');
}
});
$('#discount').on('change', function(){
var value = $(this).val();
$('.range-slider').foundation('slider', 'set_value', value);
discount_compute();
});
});

I would like to run a function, when a checkbox is checked and stop that function, when the checkbox is not checked.
This is how I tried it:
$('#auto').on('click', function() {
if ($(this).is(':checked')) {
// Interval
var autoInterval = window.setInterval(function() {
navi('next');
}, 1500);
}
else {
clearInterval(autoInterval);
}
});
The problem is clearInterval() does not work and I get no errors.
https://jsfiddle.net/n339tzff/9/
It will work if my code looks like this:
// Interval
var autoInterval = window.setInterval(function() {
navi('next');
}, 1500);
// Auto Play
$('#auto').on('click', function() {
if ($(this).is(':checked')) {
autoInterval;
}
else {
clearInterval(autoInterval);
}
});
But then I have another problem... I only want to run the function navi('next') when I click on the checkbox and not at the beginning.
When you click, it calls the setInterval and stores the result of the call in the autoInterval and after ending the function removes it. So you store and lost the value of your variable every time in the same call.
Declare the autoInterval variable outside of the event handler, to make it independent from the event handler's scope. Also you can wrap your function with a IIFE to not mutate this variable outside
(function() {
var autoInterval;
$('#auto').on('click', function() {
if ($(this).is(':checked')) {
autoInterval = window.setInterval(function() {
navi('next');
}, 1500);
} else {
clearInterval(autoInterval);
}
});
})();
You should define autoInterval outside of the event handler function, as after the event has run this variable would be 'discarded'/un-accessable.
var autoInterval = null;
$('#auto').on('click', function () {
if ($(this).is(':checked')) {
autoInterval = window.setInterval(function () {
navi('next');
}, 1500);
}
else if(autoInterval !== null) {
clearInterval(autoInterval);
autoInterval = null;
}
});
Im looking for a way to run a function when the other function is ready.
This is the function:
$(".box").first().show(150, function showNext () {
$(this).next(".box").show(150, showNext);
});
So Im look for a way to run another function after that, for example:
alert("Done");
I've tried this but didn't work.
$(".box").first().show(150, function showNext () {
$(this).next(".box").show(150, showNext);
}, function () {
alert("Done");
});
What I want is, in words:
if(all .box is visble or if showNext is idle/completed){
alert("Done");
}
I appreciate any help! Thanks.
How about :
$(".box").first().show(150, function showNext () {
var next = $(this).next(".box");
if (next.length > 0) { // If a next sibling with class "box" was found
next.show(150, showNext);
} else { // No sibling found, end reached
alert("Done");
}
});
is there any chance to create a function that i can call?
if i'm putting the following lines in the document ready function it works:
Caman("25-02-2014_16-37-13.jpg", "#example-canvas", function () {
this.brightness(brightness);
this.render(function () {
check = this.toBase64();
});
But if i'm doing this i can't call. So I tried this:
function icancall()
{
Caman("25-02-2014_16-37-13.jpg", "#example-canvas", function () {
this.brightness(brightness);
this.render(function () {
check = this.toBase64();
});
}
So i thought i can call this with icancall(); But nothing happened. What am I doing wrong?
What i want do: executing the Caman function on a button click.
I hope you can help me !
function resz(){
Caman("25-02-2014_16-37-13.jpg", "#example-canvas", function () {
try {
this.render(function () {
var image = this.toBase64();
xyz(image); // call that function where you pass filters
});
} catch (e) { alert(e) }
});
}
[Apply CamanJS filters by this function]
function xyz(image){
var filters_k = $('#filters');
filters_k.click(function (e) {
e.preventDefault();
var f = $(this);
if (f.is('.active')) {
// Apply filters only once
return false;
}
filters_k.removeClass('active');
f.addClass('active');
var effect = $.trim(f[0].id);
Caman(canvasID, img, function () {
if (effect in this) {
this.revert(false);
this[effect]();
this.render();
}
});
});
}
I'm new to JavaScript and I'm having problems with this script.
it's part of a web game and the script is suppose to refresh the page until the player wins or loses.
for some reason it doesn't stop refreshing, I put an alert function to check if the functions works, and i get the alerts but it's still continue refreshing the page.
what am i doing wrong?
var t;
$(document).ready(function () {
intervals();
});
function intervals() {
t = self.setInterval('refreshData()', 10000);
}
function youWin() {
var f = $('#status:contains("YOU ARE THE WINNER!")');
if (f.length > 0) {
alert("YOU ARE THE WINNER!");
t = clearInterval(t);
}
}
function youlose() {
var f = $('#status:contains("You lost!")');
if (f.length > 0) {
alert("You lost!");
t = clearInterval(t);
}
}
function refreshData() {
$('#ajaxGame').load('RefreshCurrentPlayerServlet #ajaxGame');
youWin();
youlose();
}
You need to fix the reference to self and fix the .load() call.
.load() is asynchronous so it does not complete before you call youWin() and youLose() right after it. You need a completion function so you can check winning or losing after the .load() completes successfully.
refreshData() should be structured like this:
function refreshData() {
$('#ajaxGame').load('RefreshCurrentPlayerServlet #ajaxGame', function() {
youWin();
youlose();
});
}
You also should change this:
t= self.setInterval('refreshData()',10000);
to this:
t = window.setInterval(refreshData, 10000);
I don't see that self was even defined so that could have also been causing your problem and you should use the function reference directly rather than put in a string.
And, as a cleanup issue, you should change both occurences of this:
t = clearInterval(t);
to this:
clearInterval(t);
Here's a cleaned up version of the code that also eliminates global variables and unnecessary function definitions:
$(document).ready(function() {
var t = window.setInterval(function() {
$('#ajaxGame').load('RefreshCurrentPlayerServlet #ajaxGame', function() {
youWin();
youlose();
});
}, 10000);
function youWin() {
if ($('#status:contains("YOU ARE THE WINNER!")').length) {
alert("YOU ARE THE WINNER!");
clearInterval(t);
}
}
function youlose() {
if ($('#status:contains("You lost!")').length) {
alert("You lost!");
clearInterval(t);
}
}
});
I have two actions I need to apply to a set of DIV's, but I need one cycle to happen before the other is finished.
Here is my code:
$("div").each(function(){
//do stuff first
}).each(function(){
//do stuff next
});
but at present, do stuff next happens before do stuff first finishes. Anything I can do to stop this?
Full Script
$("div").each(function(){
if($(this).html() === "yes"){
$(this).fadeOut(time,function(){
$(this).parent().height(0);
});
}
}).each(function(){
if($(this).html() !== "yes"){
$(this).parent().height(25);
$(this).fadeIn(time);
}
});
Knowing that you want to fadeIn and then set height, will this do what you require?
var divs = $('div');
divs.fadeIn(function () {
divs.height('200');
});
Using each to allow different settings for different divs:
$('div').each(function () {
var div = $(this), toggle = true;
div.fadeIn(function () {
if (toggle = !toggle) {
div.height('200');
} else {
div.width('200');
}
});
});
Seeing your code snippet I believe I got it now:
var yesDivs = $('div').filter(function () {
return $(this).html() === 'yes';
});
yesDivs.fadeOut(time, function () {
yesDivs.parent().height(0);
$('div').filter(function () {
return $(this).html() !== 'yes';
}).fadeIn(time).parent().height(25);
});
