jQuery boilerplate call functions - javascript

i use jQuery Boilerplate: http://jqueryboilerplate.com/
and now i have a problem to call a function in a function..
i can't call "openOverlay" in "clickEvents", but i can call "openOverlay" in "init".
here is a snippet:
Plugin.prototype = {
init: function() {
var $me = $(this.element);
this.clickEvents($me);
},
clickEvents: function($el, func) {
$el.on('click', function() {
var $me = $(this);
var overlayName = $me.data('overlay');
this.openOverlay(overlayName);
});
},
openOverlay: function(overlayName) {
var $overlayContainer = $(defaults.$overlayContainer);
var $overlay = $overlayContainer.find('[data-overlay="' + overlayName + '"]');
$overlayContainer.fadeIn(500);
$overlay.delay(500).fadeIn(500);
}
};

the problem is that the on click function overrides "this"
try:
var self=this;
$el.on('click', function() {
var $me = $(this);
var overlayName = $me.data('overlay');
self.openOverlay(overlayName);
});

Default filtering item

I have a page like this page:
http://www.sungeetheme.com/html/our_gallery_3_colums.html
In the filtering Gallery, the default item is "all"
How do I change the default to something else on page load, for example: Portrait?
I tried to change in the code section the variable dataFilterVal from "All" to something else and it did not work well
var masonryFilter = {
massMasonry: [],
dataFilterVal: "all",
init: function () {
var self = this;
self.filterEl('.j-filter', '~ .j-filter-content');
self.masonry();
},
masonry: function () {
var self = this;
var msnry;
var i = 0;
$('.j-masonry').each(function () {
var el = $(this),
newClass = 'j-masonry-' + i;
el.addClass(newClass).attr('data-masonry-id', i);
i++;
el.imagesLoaded(function () {
var container = document.querySelector('.' + newClass);
msnry = new Masonry(container,
{
itemSelector: '.j-masonry-item',
columnWidth: '.' + newClass + ' .masonry-gridSizer',
transitionDuration: '1.2s'
});
self.massMasonry.push(msnry);
el.data('masonry', msnry);
});
});
},
filterEl: function (filterNav, filterContent) {
var self = this;
$(filterNav + ' a').click(function (e) {
e.preventDefault();
var el = $(this);
var activeClass = "is-category-filter-active";
var activeContainer = $(filterContent, $(this).parents(filterNav)).eq(0);
console.log(activeContainer);
$('li', $(this).parents(filterNav)).removeClass(activeClass);
el.closest('li').addClass(activeClass);
self.dataFilterVal = el.attr('data-filter');
self.filterStart(self.dataFilterVal, activeContainer);
});
},
filterStart: function (dataFilterVal, filterContent) {
var self = this;
if (dataFilterVal == "all") {
$('[class*="j-filter-"]', filterContent).show().stop(true, false).animate({
opacity: 1
}, 400);
} else {
var hideItems = $('[class*="j-filter-"]', filterContent).not(dataFilterVal);
hideItems.stop(true, false).animate({
opacity: 0
}, 400);
setTimeout(function () {
hideItems.hide();
}, 301);
$(dataFilterVal, filterContent).show().stop(true, false).animate({
opacity: 1
}, 400);
}
setTimeout(function () {
var masonryId = $(filterContent).find('.j-masonry').attr('data-masonry-id');
self.massMasonry[masonryId].layout();
}, 501);
}
};
masonryFilter.init();

prevent slideshow from refresh or load content in div

I have a nice working image slideshow, but every time when i open a new page from the menu, the slideshow starts from the beginning. I want it to go on where it was while entering a new page. Now could there be a possibility to change it in the code of my slideshow, but maybe a better solution is to open my content in a div with AJAX, so the whole page doesn't refresh.
I found this on the web:
<div id="navigatie">
<div id="buttons">
<a class="menu" id="page1" href="#">Home</a><span>|</span>
<a class="menu" id="page2" href="#">Projects</a><span>|</span>
<a class="menu" id="page3" href="#">About</a><span>|</span>
</div>
</div>
<script>
$(document).ready(function() {
$("#page1").click(function(){
$('#content').load('index.php #content');
});
$("#page2").click(function(){
$('#content').load('projects.php #content');
});
$("#page3").click(function(){
$('#content').load('about.php #content');
});
});
</script>
But this doesn't workout very well because when i start with my index page and go to projects (where lightbox is present), i get full images instead of thumbnails.(This was because the extended files were not in #content) i get index.php# instead of projects.php. Maybe i should use an easier solution, but im getting stuck. Can someone help me out please?
Edit: Let me also share the code of the slideshow with you, perhaps there is a possibility to resume after loading a new page/refresh.

Its fixed, i just load my content in the #content div and i changed every 'href' to #Home (or name i like) in combination with Benalman's hashchange script

jquery object - function undefined error

In the following function, my objects inside floatShareBar function is undefined. Do I have to init or define a var before the functions? it throws me js error : .float - function undefined.
(function($) {
.
.
.
$("body").on("ab.snap", function(event) {
if (event.snapPoint >= 768) {
floatShareBar.float()
} else {
floatShareBar.unfloat();
}
});
var floatShareBar = function() {
var fShareBar = $('#article-share');
this.float = function() {
console.log(
};
this.unfloat = function() {
console.log("unfloat");
};
};
.
.
.
})(jQuery);
You need to get an instance of that function with a self instantiating call:
var floatShareBar = (function() {
var fShareBar = $('#article-share');
this.float = function() {
console.log('float');
};
this.unfloat = function() {
console.log("unfloat");
};
return this;
})();
UPDATE 1: I modified it to create an object within the function to attach those functions to, since in the previous example this refers to the window object
var floatShareBar = (function() {
var fShareBar = $('#article-share');
var instance = {};
instance.float = function() {
console.log('float');
};
instance.unfloat = function() {
console.log("unfloat");
};
return instance;
})();
UPDATE 2: You can actually just use the new keyword as well, look here for more info
var floatShareBar = new (function() {
var fShareBar = $('#article-share');
this.float = function() {
console.log('float');
};
this.unfloat = function() {
console.log("unfloat");
};
})();
Change you function to this:
$("body").on("ab.snap", function(event) {
if (event.snapPoint >= 768) {
(new floatShareBar()).float()
} else {
(new floatShareBar()).unfloat();
}
});
function floatShareBar () {
var fShareBar = $('#article-share');
this.float = function() {
console.log(
};
this.unfloat = function() {
console.log("unfloat");
};
};
you should declare functions when using var before you call them.

call custom event dynamically on jquery plugin

I have a plugin with the following structure:
(function($){
function pluginName(el, options) {
var _this = this;
_this.defaults = {
someOptions: '',
onSlideStart: function() {},
onSlideEnd: function() {},
};
_this.opts = $.extend({}, _this.defaults, options);
$(el).on("slideStart", function() {
_this.opts.onSlideStart.call();
});
$(el).on("slideEnd", function() {
_this.opts.onSlideEnd.call();
});
}
pluginName.prototype = {
someFunctions: function() {
}
};
$.fn.pluginName = function(options) {
if(this.length) {
this.each(function() {
var rev = new pluginName(this, options);
rev.init();
$(this).data('pluginName', rev);
});
}
};
})(jQuery);
If I call it the following way, everything is okay:
$('.element').pluginName({
someOptions: 'full',
onSlideStart: function() {
console.log('slideStart!');
},
onSlideEnd: function() {
console.log('slideEnd!');
},
});
But I want to dynamic load the custom event handler like this:
(function($){
function pluginName(el, options) {
var _this = this;
_this.defaults = {
someOptions: '',
onSlideStart: function() {},
onSlideEnd: function() {},
};
_this.opts = $.extend({}, _this.defaults, options);
for (var optionName in _this.opts) {
var
optionValue = _this.opts[optionName],
optionType = typeof(optionValue)
;
if(optionType == 'function') {
optionNames = optionName.split('on');
eventName = global.lowerFirstLetter(optionNames[1]);
$(el).on(eventName, function() {
eval('_this.opts.' + optionName + '.call();');
});
}
}
}
...
})(jQuery);
But this does not work. When I call the plugin with the "dynamic" part, it always call the slideEnd-function. So am I doing it wrong or is it just impossible with my plugin-pattern to call the custom event-handler dynamically?
Why use eval ? It's usually bad to use eval.
if(optionType == 'function') {
optionNames = optionName.split('on');
eventName = global.lowerFirstLetter(optionNames[1]);
$(el).on(eventName, _this.opts[optionName]);
}
Try it and let me know.

Module pattern jQuery

I'm having a problem using the module pattern in a very dummy javascript code.
This code is working perfectly:
;
var test = (function () {
var config = {
replacement: 'a'
};
var init = function () {
$(config.replacement).click(function(){
alert("hello world");
});
}
return {
init: init
}
})();
$(document).ready(test.init());
Instead, this code is not working when I click on any link of my website:
;
var test = (function () {
var config = {
replacement: $('a')
};
var init = function () {
config.replacement.click(function(){
alert("hello");
});
}
return {
init: init
}
})();
$(document).ready(test.init());
Anyone could tell me why I can not use a jQuery object as "default" initialization of config variable.
The $(a) is executed before DOM ready, probably when no a elements are accessible.
In your first example, the set was constructed after DOM ready.
You could turn it into a function instead...
var config = {
replacement: function() { return document.links; }
};
Then, Why in this example located in official jQuery website using a jQuery selector is working for the default config vars?
var feature = (function () {
var $items = $("#myFeature li");
var $container = $("<div class='container'></div>");
var $currentItem = null;
var urlBase = "/foo.php?item=";
var createContainer = function () {
var $i = $(this);
var $c = $container.clone().appendTo($i);
$i.data("container", $c);
},
buildUrl = function () {
return urlBase + $currentItem.attr("id");
},
showItem = function () {
$currentItem = $(this);
getContent(showContent);
},
showItemByIndex = function (idx) {
$.proxy(showItem, $items.get(idx));
},
getContent = function (callback) {
$currentItem.data("container").load(buildUrl(), callback);
},
showContent = function () {
$currentItem.data("container").show();
hideContent();
},
hideContent = function () {
$currentItem.siblings().each(function () {
$(this).data("container").hide();
});
};
$items.each(createContainer).click(showItem);
return {
showItemByIndex: showItemByIndex
};
})();
$(document).ready(function () {
feature.showItemByIndex(0);
});
