hidding elements in a layout page mvc3 - asp.net-mvc-3

Question

ok so im having a hard time hiding some layout sections (divs in my layout page and im using mvc3).
I have this js fragment which is basically the main logic:
$('.contentExpand').bind('click', function () {
$.cookie('right_container_visible', "false");
});
//Cookies Functions========================================================
//Cookie for showing the right container
if ($.cookie('right_container_visible') === 'false') {
if ($('#RightContainer:visible')) {
$('#RightContainer').hide();
}
$.cookie('right_container_visible', null);
} else {
if ($('#RightContainer:hidden')) {
$('#RightContainer').show();
}
}
as you can see, im hidding the container whenever i click into some links that have a specific css. This seems to work fine for simple tests. But when i start testing it like
.contentExpand click --> detail button click --> .contentExpand click --> [here unexpected issue: the line $.cookie('right_container_visible', null); is read but it doesnt set the vaule to null as if its ignoring it]
Im trying to understand whats the right logic to implement this. Anyone knows how i can solve this?

Answer 1

The simpliest solution is to create variable outside delegate of bind.
For example:
var rightContVisibility = $.cookie('right_container_visible');
$('.contentExpand').bind('click', function () {
$.cookie('right_container_visible', "false");
rightContVisibility = "false";
});
if (rightContVisibility === 'false') {
...
}

The best thing that worked for me was to create an event that can catch the resize of an element. I got this from another post but I dont remember which one. Anyway here is the code for the event:
//Event to catch rezising============================================================================
(function () {
var interval;
jQuery.event.special.contentchange = {
setup: function () {
var self = this,
$this = $(this),
$originalContent = $this.text();
interval = setInterval(function () {
if ($originalContent != $this.text()) {
$originalContent = $this.text();
jQuery.event.handle.call(self, { type: 'contentchange' });
}
}, 100);
},
teardown: function () {
clearInterval(interval);
}
};
})();
//=========================================================================================
//Function to resize the right container============================================================
(function ($) {
$.fn.fixRightContainer = function () {
this.each(function () {
var width = $(this).width();
var parentWidth = $(this).offsetParent().width();
var percent = Math.round(100 * width / parentWidth);
if (percent > 62) {
$('#RightContainer').remove();
}
});
};
})(jQuery);
//===================================================================================================
