Functions are not working in js prototype

I have developed a jQuery plugin with prototypal inheritance.But functions are only working for main init() function and other prototypes are not working.
My main function is
function Mynav(){
....
}
Mynav.prototype.linkBehaviour = function(){
$('.nav-menu li a').on('click', function(e) {
if ($(this).attr('href') !== '#') {
var link = $(this).attr('href');
$('#preloader').removeClass('fadeOut').addClass('fadeIn').fadeIn('slow');
setTimeout(function() {
window.location = link;
}, 1500)
} else if ($(this).attr('href') == '#') {
e.preventDefault();
}
});
}
Mynav.prototype.verticalConverter = function(){
if (verticalNavOn) {
if(!verticalLive){
menuConverter();
verticalLive = true;
}
}
$(window).on('load resize', function(){
width = $(window).width();
if(width < 959){
if(!verticalLive){
menuConverter(); //This is a function also available with Mynav.prototype.menuConverter
header.removeAttr('style');
verticalLive = true;
}
} else{
convertHorizontal(); // Its also a function available
$('.header-fixed').attr('style',headerAttr);
verticalLive = false;
}
});
}
function init(){
new Mynav();
}
init();
In the upper codes linkBehaviour and verticalconverter is not working if i place linkBehaviour function in the main Mynav() it works then but not working in individual.
And i don't actually know about load/resize works with prototype or not .
Can any one help About the above two functions?

function Mynav(){
this.verticalNavOn = false;
}
Mynav.prototype.linkBehaviour = function(){
$('.nav-menu li a').on('click', function(e) {
if ($(this).attr('href') !== '#') {
var link = $(this).attr('href');
$('#preloader').removeClass('fadeOut').addClass('fadeIn').fadeIn('slow');
setTimeout(function() {
window.location = link;
}, 1500)
} else if ($(this).attr('href') == '#') {
e.preventDefault();
}
});
}

* I believe that is in trouble when the RESIZE happens.

*/
Mynav.prototype.verticalConverter = function(){
var self = this;
if (self.verticalNavOn) {
if(!self.verticalLive){
self.menuConverter();
self.verticalLive = true;
}
}
// parse THIS plugin for EVENT
$(window).on('load resize', {self: self}, function(e){
// get SELF PLUGIN
var self = e.data['self'];
width = $(window).width();
if(width < 959){
if(!self.verticalLive){
self.menuConverter(); //This is a function also available with Mynav.prototype.menuConverter
header.removeAttr('style');
self.verticalLive = true;
}
} else{
self.convertHorizontal(); // Its also a function available
$('.header-fixed').attr('style',headerAttr);
self.verticalLive = false;
}
});
}
function init(){
var x = new Mynav();
// focing start function for tests
x.verticalConverter();
}
init();

jQuery Appear Function

I'm trying to use the jQuery appear plugin. I'm having trouble making it work. I tried to attach it to the (window).scroll event but it makes the page slow. If I don't use the scroll, it only fires once. I need it to work again whenever the element becomes visible. Can you give me some tips on how to make it work.
Here's my code:
jQuery('.home-section-1').appear(function(){
jQuery('.page-scroll-indicator .fa.fa-circle').removeClass('active-ind');
jQuery('.page-scroll-indicator .section-1').addClass('active-ind');
});

As ɴ-ᴀ-ᴛ-ʜ said in his comment, you need to be using .on to listen for the appear event.
jQuery('.home-section-1').on('appear', function(){
jQuery('.page-scroll-indicator .fa.fa-circle').removeClass('active-ind');
jQuery('.page-scroll-indicator .section-1').addClass('active-ind');
});
Here's a code snippit showing it working, you'll notice that your method (Method 1) doesn't fire, while the method above (Method 2) does:

After looking through your code, there were numerous errors with syntax. I have cleaned them up as best as I could, this should help you out.
http://jsfiddle.net/wvWrY/1/
For example, this area was missing a semicolon (no way to call the findElements function, as JS will simply skip to the next line without a semicolon there.)
init: function() {
this.findElements()
this.setStructure();
this.addEvents();
Run your code through a linter, it will greatly improve your syntax structure and ensure little leave out errors like semicolons and commas and brackets aren't omitted.
EDIT: Ok, having looked at your code it appears this is actually due to the !importants in your allmobile.css file. The width and height are set to max-width: 100% (this breaks it because the way the slider works is to extend the gallery as far off screen as possible) and the height to auto (this breaks it because it allows the images to just keep piling on). Once you remove those for the page, it become much much much better and actually works.

jquery conflict with js script

welcome all ,
i have a problem with my images slider , it runs successfuly until poll script excuted then it stops , tried to combine both scripts didn't work also tried to use noConflict but in stops both of them .
this is the slider
(function ($) {
$.fn.s3Slider = function (vars) {
var element = this;
var timeOut = (vars.timeOut != undefined) ? vars.timeOut : 4000;
var current = null;
var timeOutFn = null;
var faderStat = true;
var mOver = false;
var items = $("#sliderContent .sliderImage");
var itemsSpan = $("#sliderContent .sliderImage span");
items.each(function (i) {
$(items[i]).mouseover(function () {
mOver = true
});
$(items[i]).mouseout(function () {
mOver = false;
fadeElement(true)
})
});
var fadeElement = function (isMouseOut) {
var thisTimeOut = (isMouseOut) ? (timeOut / 2) : timeOut;
thisTimeOut = (faderStat) ? 10 : thisTimeOut;
if (items.length > 0) {
timeOutFn = setTimeout(makeSlider, thisTimeOut)
} else {
console.log("Poof..")
}
};
var makeSlider = function () {
current = (current != null) ? current : items[(items.length - 1)];
var currNo = jQuery.inArray(current, items) + 1;
currNo = (currNo == items.length) ? 0 : (currNo - 1);
var newMargin = $(element).width() * currNo;
if (faderStat == true) {
if (!mOver) {
$(items[currNo]).fadeIn((timeOut / 6), function () {
if ($(itemsSpan[currNo]).css("bottom") == 0) {
$(itemsSpan[currNo]).slideUp((timeOut / 6), function () {
faderStat = false;
current = items[currNo];
if (!mOver) {
fadeElement(false)
}
})
} else {
$(itemsSpan[currNo]).slideDown((timeOut / 6), function () {
faderStat = false;
current = items[currNo];
if (!mOver) {
fadeElement(false)
}
})
}
})
}
} else {
if (!mOver) {
if ($(itemsSpan[currNo]).css("bottom") == 0) {
$(itemsSpan[currNo]).slideDown((timeOut / 6), function () {
$(items[currNo]).fadeOut((timeOut / 6), function () {
faderStat = true;
current = items[(currNo + 1)];
if (!mOver) {
fadeElement(false)
}
})
})
} else {
$(itemsSpan[currNo]).slideUp((timeOut / 6), function () {
$(items[currNo]).fadeOut((timeOut / 6), function () {
faderStat = true;
current = items[(currNo + 1)];
if (!mOver) {
fadeElement(false)
}
})
})
}
}
}
};
makeSlider()
}
})(jQuery);
and this is the poll script
window.onload = function() {
$(".sidePollCon").load("ar_poll.html", function(r, s, xhr) {
if (s == "error") {
$(".sidePollCon").load("poll.html");
} else {
$(".vote_booroo").html("صوت الان");
$(".viewresults").html("شاهد النتيجة");
$("fieldset p").html("");
$(".results_booroo p").html("");
$(".result_booroo").attr("src", "../images/poll_color.jpg");
}
});
};

One potential problem could be the window.onload assignment. It is very prone to conflict.
Every time you do window.onload = the previous assignemnt will be overridden. See demo here:
The output shows that the first window.onload assignment never gets called, while the jQuery alternative does get called.
jQuery.noConflict does little in this regard. All it does is to prevent override the $ symbol so that another lib can use it.
So if you are also using the window.onload event to invoke the slider, then you have conflict. You can easily solve this problem by using the jquery format:
$(window).load(function() {
...
});
However usually you would tie the event to $(document).load(function(){...}); or in short form: $(function(){...}).
So for your poll that would be:
$(function(){
$(".sidePollCon").load("ar_poll.html", function(r, s, xhr) {
if (s == "error") {
$(".sidePollCon").load("poll.html");
} else {
$(".vote_booroo").html("صوت الان");
$(".viewresults").html("شاهد النتيجة");
$("fieldset p").html("");
$(".results_booroo p").html("");
$(".result_booroo").attr("src", "../images/poll_color.jpg");
}
});
});
Hope that helps.

resolving conflicts in jquery (possibly with another JS library .. like script.aculo.us) can be resolved using noconflict()
http://api.jquery.com/jQuery.noConflict/
$.noConflict();
but make sure that u have no error in your javascript code itself. use firebug and
console.log('') to test your script.

Javascript causing memory leak [closed]

Closed. This question needs details or clarity. It is not currently accepting answers.
Want to improve this question? Add details and clarify the problem by editing this post.
Closed 5 years ago.
Improve this question
I can't for the life of me figure out why loading this page...
http://polyphonic.hannahkingdev.com/work/cowboys-angels or any other video page sometimes causes the browser to hang and then prompts me to stop the script that is causing the browser to slowdown.
If the video is left to run, by the time you go to close the page, the browser is pretty unresponsive. This is the same in FFox, Safari & Chrome.
Any help finding the memory leak would be most appreciated. I am completely stumped on this one.
Many thanks

$('.controls').fadeIn();
isMouseMove=true;
}
function hidePlayerControls() {
$('.controls').fadeOut();
}
function hidePlayerControls() {
setInterval(function() {
if (!isMouseMove) {
hidePlayerControls();
}
isMouseMove=false;
}, 4000);
$(document).mousemove(function (event) {
isMouseMove=true;
showPlayerControls();
});
}

The most likely cause is this code here:
function hidePlayerControls() {
setInterval(function() {
if (!isMouseMove) {
hidePlayerControls();
}
isMouseMove=false;
}, 4000);
so every 4 seconds you start a new interval (interval = repeat until cancelled).
In the first case, you might like to change this to setTimeout
function hidePlayerControls() {
setTimeout(function() {
if (!isMouseMove) {
hidePlayerControls();
}
isMouseMove=false;
}, 4000);
In the second, you could change this to cancel the previous timeout when the mouse moves - this is termed debouncing - though usually with a shorter interval, the principle is the same.
As a general debugging tip, liberally add console.log statements and watch your browser console (there are other ways, this is a basic debugging first-step), eg:
function hidePlayerControls() {
console.log("hidePlayerControls() called");
setInterval(function() {
console.log("hidePlayerControls - interval triggered", isMouseMove);
if (!isMouseMove) {
hidePlayerControls();
}
isMouseMove=false;
}, 4000);
to see just how many times this gets called
