How do I find out which js file is responsible for a certain element?

I am testing my page in Chrome. I right click on the element that I am having issues with and I get this:
element.style {
height: 147px;
position: relative;
width: 100%;
overflow: hidden;
}
without a file attached to it. This tells me that the element style is coming from either an inline code (my page has none) or a js file (which my page has a number).
When I turn off the position: relative, I no longer have any issues.
I think I have narrowed it down to one js file that is screwing up my page, but I don't have a clue as to how to fix it or how to figure it out.
Here are some images better describing the issue:
http://i.imgur.com/Yxv2zLe.png
http://i.imgur.com/wtqkqw5.png
If you look at the first image, the blue box over the image needs to be directly over the orange box so that everything lines up properly.
In the second image, when I turn off the position, the image is positions correctly under the overlay.
My problem is that I don't know enough about js to fix the code to fix the position.
Here is the code that I think is responsible, if it helps.

Bootstrap Lightbox: Showing image captions from title attribute

Still very new at Javascript and jQuery, so this one is tough for me.
I'm using this Bootstrap Lightbox plugin: https://github.com/duncanmcdougall/Responsive-Lightbox
Trying to use it on this site (WIP): http://lastdetailwd.com/modernmetalfabricators/furniture.html
I'm looking to use the title attribute from the A tags as captions for this lightbox. Any clue on how to get this done?
jQuery:
(function ($) {
'use strict';
$.fn.lightbox = function (options) {
var opts = {
margin: 50,
nav: true,
blur: true,
minSize: 0
};
var plugin = {
items: [],
lightbox: null,
image: null,
current: null,
locked: false,
selector: "#lightbox",
init: function (items) {
plugin.items = items;
plugin.selector = "lightbox-"+Math.random().toString().replace('.','');
if (!plugin.lightbox) {
$('body').append(
'<div id="lightbox" class='+plugin.selector+' style="display:none;">'+
'' +
'<div class="lightbox-nav">'+
'' +
'' +
'</div>' +
'</div>'
);
plugin.lightbox = $("."+plugin.selector);
}
if (plugin.items.length > 1 && opts.nav) {
$('.lightbox-nav', plugin.lightbox).show();
} else {
$('.lightbox-nav', plugin.lightbox).hide();
}
plugin.bindEvents();
},
loadImage: function () {
if(opts.blur) {
$("body").addClass("blurred");
}
$("img", plugin.lightbox).remove();
plugin.lightbox.fadeIn('fast').append('<span class="lightbox-loading"></span>');
var img = $('<img src="' + $(plugin.current).attr('href') + '" draggable="false">');
$(img).load(function () {
$('.lightbox-loading').remove();
plugin.lightbox.append(img);
plugin.image = $("img", plugin.lightbox).hide();
plugin.resizeImage();
});
},
resizeImage: function () {
var ratio, wHeight, wWidth, iHeight, iWidth;
wHeight = $(window).height() - opts.margin;
wWidth = $(window).outerWidth(true) - opts.margin;
plugin.image.width('').height('');

} else {
$(plugin.items[plugin.getCurrentIndex() - 1]).click();
}
},
bindEvents: function () {
$(plugin.items).click(function (e) {
if(!$("#lightbox").is(":visible") && ($(window).width() < opts.minSize || $(window).height() < opts.minSize)) {
$(this).attr("target", "_blank");
return;
}
var self = $(this)[0];
e.preventDefault();
plugin.current = self;
plugin.loadImage();
// Bind Keyboard Shortcuts
$(document).on('keydown', function (e) {
// Close lightbox with ESC
if (e.keyCode === 27) {
plugin.close();
}
// Go to next image pressing the right key
if (e.keyCode === 39) {
plugin.next();
}
// Go to previous image pressing the left key
if (e.keyCode === 37) {
plugin.previous();
}
});
});
// Add click state on overlay background only
plugin.lightbox.on('click', function (e) {
if (this === e.target) {
plugin.close();
}
});
// Previous click
$(plugin.lightbox).on('click', '.lightbox-previous', function () {
plugin.previous();
return false;
});
// Next click
$(plugin.lightbox).on('click', '.lightbox-next', function () {
plugin.next();
return false;
});
// Close click
$(plugin.lightbox).on('click', '.lightbox-close', function () {
plugin.close();
return false;
});
$(window).resize(function () {
if (!plugin.image) {
return;
}
plugin.resizeImage();
});
},
close: function () {
$(document).off('keydown'); // Unbind all key events each time the lightbox is closed
$(plugin.lightbox).fadeOut('fast');
$('body').removeClass('blurred');
}
};
$.extend(opts, options);
plugin.init(this);
};
})(jQuery);

Author did just update it to include captions. Closing this.

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.

Javascript Viewport Fade In Fade Out

I'm trying to accomplish something so simple it's painful, but I've yet to have luck after hours of work.
I have 4 divs, each with the class '.slide'. All I want to do is have them invisible, but fade in when they are in the viewport. If they leave the viewport, they should return to invisible. Any ideas?
$('.slide').waypoint(
function() {
if( $(this).is(":in-viewport") ) {
$(this).animate({
opacity: 1
}, 100);
}
$('.slide').not(this).animate({
opacity: 0
}, 100);
},
{
offset: function() {
return $.waypoints('viewportHeight') - document.getElementById('navigation').clientHeight;
}
}
);
http://jsfiddle.net/Agdax/3/

So i played a little and got this:
/*jslint browser: true */
/*global $ */
(function () {
'use strict';
var invisibleClassName = 'invisible',
scrollWait = 500;
function isInvisible(el) {
var wh = $(window).height(),
wt = $(window).scrollTop(),
eh = $(el).height(),
et = $(el).offset().top;
return ((wh + wt) <= et || wt >= (et + eh));
}
function checkVisibleAll(elements) {
elements.each(function () {
$(this)[(isInvisible(this) ? 'add' : 'remove') + 'Class'](invisibleClassName);
});
}
$.fn.visible = function () {
var elements = this,
scrollTimer = null;
// Don't check too often
function scrolled() {
clearTimeout(scrollTimer);
scrollTimer = setTimeout(function () {
checkVisibleAll(elements);
}, scrollWait);
}
// Onload
checkVisibleAll(elements);
$(window).bind("scroll resize", scrolled);
return this;
};
}());
Animation is visible in modern browsers.

Javascript causing memory leak [closed]

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

$(document).mousemove(function (event) {

}

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
