How to avoid collapse menubar and cover carousel in website?

first of all im sorry for taking your time. I used album cover slider and superfish in my first site and they collapsed. I can use slider perfectly but i cant use my menu. Submenus and everything shows when i take my cursor to there. I want to learn how to avoid click collapse in js projects, little explanation would help me big time.
Here are the JS's.

when click on button the time is count and show totall time

hi gyzz i am new in jquery , when i click add button the running time is count suddenly when i click add button and its count , i click 3 times and its count different time and when i click totall button then show total time that i click 3 times add 3 different time , how this is possible... i use simple stopwatch plugin..
my code is
(function( $ ){
//my code
$('#demo1').stopwatch().stopwatch('start');
//count time indually
$(".add_time").click(function(e) {
e.preventDefault();
var time_record = $('.example').find('#timer').text();
var time_record++;
console.log(time_record);
});
//get totall time
$(".totall_time").click(function(e) {
e.preventDefault();
});

jQuery extended function preserve chaining based on condition

I'm trying to create a jquery build it function which will allow me to change maxHeight or retrieve maxHeight from an element or a set of elements.
setting a maxHeight by : $('.element-class').maxHeight(500); works great.
However when I dont pass a parameter in maxHeight() I'd like to return the element's height and not preserve jquery chainability:
Source:
(function($) {
// jQuery plugin definition
$.fn.maxHeight = function() {
var params = arguments;
var $this = this;
console.log(params);
this.each(function() {
var $t = $(this);
if (params.length > 0 ) {
if (params[0] == 'none'){
$t.get(0).style.maxHeight = 'none';
} else {
$t.get(0).style.maxHeight = params[0] + 'px';
}
return $t;
} else {
var h = (($t.get(0).style.maxHeight && $t.get(0).style.maxHeight != '') ? parseInt($t.get(0).style.maxHeight) : 0);
console.log(h);
return h;
}
});
return this;
};
})(jQuery);

I think you have to make a callback function, didn't have time to test it but try this:
(function($) {
// jQuery plugin definition
$.fn.maxHeight = function(a, callback) {
var $this = this;
this.each(function() {
var $t = $(this);
if (!a) {
$t.get(0).style.maxHeight = 'none';
} else {
$t.get(0).style.maxHeight = a + 'px';
}
callback($t);
} else {
var h = (($t.get(0).style.maxHeight && $t.get(0).style.maxHeight != '') ? parseInt($t.get(0).style.maxHeight) : 0);
callback(h);
}
});
};
})(jQuery);
and then do something like this:
$('.element-class').maxHeight(500 , function(result){
// use your result or not
// Want to chain
return result;
});

JavaScript Preventing User Text Selection

Something in this Curtains.js plug-in is preventing user text selection on my page. When I comment it out, I'm able to select text, when I put it back in, I'm not. Can someone identify it and tell me how to fix it? I'm at my wit's end.

First you would have to tell us how you are trying to select text (mouse, keyboard, touchscreen, etc.)
I bet my bitcoins on keyboard (but I don't have any).
Must be one of those
self.$document.on('keydown', function(e){
...
e.preventDefault();
which don't even document which keys these numbers stand for.
It's e.preventDefault() which prevents the default browser action from being performed.
If you're in Chrome devtools, you can use
monitorEvents(window, 'key')
to make sense of these.
Of course this bit may help a bit:
keyCode: 38
keyIdentifier: "Up"
So the code could be written readably by use of keyIdentifier instead of keyCode.
I don't know how compatible that would be across browsers.
Be warned that keydown keyCode values are different from keypress values (which actually insert real characters). keydown key codes will vary between keyboard layouts and locales.
See http://unixpapa.com/js/key.html for disgust and enlightenment, but mostly disgust.

Detect if clicking outside of element (Must support clicking in overlay elements)

Current best solution i have found:
ko.bindingHandlers.clickedIn = (function () {
function getBounds(element) {
var pos = element.offset();
return {
x: pos.left,
x2: pos.left + element.outerWidth(),
y: pos.top,
y2: pos.top + element.outerHeight()
};
}
function hitTest(o, l) {
function getOffset(o) {
for (var r = { l: o.offsetLeft, t: o.offsetTop, r: o.offsetWidth, b: o.offsetHeight };
o = o.offsetParent; r.l += o.offsetLeft, r.t += o.offsetTop);
return r.r += r.l, r.b += r.t, r;
}
for (var b, s, r = [], a = getOffset(o), j = isNaN(l.length), i = (j ? l = [l] : l).length; i;
b = getOffset(l[--i]), (a.l == b.l || (a.l > b.l ? a.l <= b.r : b.l <= a.r))
&& (a.t == b.t || (a.t > b.t ? a.t <= b.b : b.t <= a.b)) && (r[r.length] = l[i]));
return j ? !!r.length : r;
}
return {
init: function (element, valueAccessor) {
var target = valueAccessor();
$(document).click(function (e) {
if (element._clickedInElementShowing === false && target()) {
var $element = $(element);
var bounds = getBounds($element);
var possibleOverlays = $("[style*=z-index],[style*=absolute]").not(":hidden");
$.each(possibleOverlays, function () {
if (hitTest(element, this)) {
var b = getBounds($(this));
bounds.x = Math.min(bounds.x, b.x);
bounds.x2 = Math.max(bounds.x2, b.x2);
bounds.y = Math.min(bounds.y, b.y);
bounds.y2 = Math.max(bounds.y2, b.y2);
}
});
if (e.clientX < bounds.x || e.clientX > bounds.x2 ||
e.clientY < bounds.y || e.clientY > bounds.y2) {
target(false);
}
}
element._clickedInElementShowing = false;
});
$(element).click(function (e) {
e.stopPropagation();
});
},
update: function (element, valueAccessor) {
var showing = ko.utils.unwrapObservable(valueAccessor());
if (showing) {
element._clickedInElementShowing = true;
}
}
};
})();
It works by first query for all elements with either z-index or absolute position that are visible. It then hit tests those elemnts against the elemnet I want to hide if click outside. If its a hit I calculate a new bound retacle which takes into acount the overlay bounds.
Its not rock solid, but works. Please feel free to comment if you see problems with above approuch
Old question
I'm using Knockout but this applies to DOM/Javascript in general
Im trying to find a reliable way if detecting of you click outside of a element. My code looks like this
ko.bindingHandlers.clickedIn = {
init: function (element, valueAccessor) {
var target = valueAccessor();
var clickedIn = false;
ko.utils.registerEventHandler(document, "click", function (e) {
if (!clickedIn && element._clickedInElementShowing === false) {
target(e.target == element);
}
clickedIn = false;
element._clickedInElementShowing = false;
});
ko.utils.registerEventHandler(element, "click", function (e) {
clickedIn = true;
});
},
update: function (element, valueAccessor) {
var showing = ko.utils.unwrapObservable(valueAccessor());
if (showing) {
element._clickedInElementShowing = true;
}
}
};
It works by both listening to click on target element and document. If you click on document but not target element you click outside of it. This works, but, not for overlay items like datepickers etc. This is because these are not inside the target element but in the body. Can I fix this? Are there better way of determine if clicking outside of element?
edit: This kind of works, but only if the overlay is smaller than the element i want to monitor
ko.bindingHandlers.clickedIn = {
init: function (element, valueAccessor) {
var target = valueAccessor();
$(document).click(function (e) {
if (element._clickedInElementShowing === false) {
var $element = $(element);
var pos = $element.offset();
if (e.clientX < pos.left || e.clientX > (pos.left + $element.width()) ||
e.clientY < pos.top || e.clientY > (pos.top + $element.height())) {
target(false);
}
}
element._clickedInElementShowing = false;
});
$(element).click(function (e) {
e.stopPropagation();
});
},
update: function (element, valueAccessor) {
var showing = ko.utils.unwrapObservable(valueAccessor());
if (showing) {
element._clickedInElementShowing = true;
}
}
};
I would like a more rock solid approuch

This is how I usually solve it:
http://jsfiddle.net/jonigiuro/KLxnV/
$('.container').on('click', function(e) {
alert('hide the child');
});
$('.child').on('click', function(e) {
alert('do nothing');
e.stopPropagation(); //THIS IS THE IMPORTANT PART
});

I don't know how your overlay items are generated, but you could always check if the click target is a child of the element you want to constrain your clicks to.
