Where do I put $(this) in the function?

Since I want to use classes instead of id's in these functions(I have three of the same function with different things I want to .append) I am sure I need to put $(this) in those functions somewhere to only trigger only ONE function on button click and not all three of them. but I am not sure because I am a total beginner in jquery/js, so I would appreciate some help.
$(document).ready(function () {
$(".onclick").click(function () {
$('#favorites').append('<div data-role="main"class="ui-content"><div class="ui-grid-b"><div class="ui-block-a">Arrow</div><div class="ui-block-b">More Info</div><div class="ui-block-c">Unfavorite</div></div></div>');
});
});
http://codepen.io/anon/pen/JYxqEw - HTML And the Jquery Code

$('.onclick') selects all the elements with a class of onclick. That means that, whenever something with class="onclick" is clicked, that function will fire.
If you want all of those elements to append that exact HTML to the #favorites element, then you can leave your code as-is.
However, if what you're trying to do is append that html to the clicked element, that is when you'd use $(this) -- that selects the element you clicked with jQuery, then you can append directly to that element ie:
$(document).ready(function () {
$(".onclick").click(function () {
// this will append the HTML to the element that triggered the click event.
$(this).append('<div data-role="main"class="ui-content"><div class="ui-grid-b"><div class="ui-block-a">Arrow</div><div class="ui-block-b">More Info</div><div class="ui-block-c">Unfavorite</div></div></div>');
});
});
EDIT
so to insert the contents of each .onclick into #favorites, you'll need to use the innerHTML value of the DOM node. example fiddle:
http://jsbin.com/qazepubuzu/edit?html,js,output
When you select something with jQuery, you're actually getting back not just the DOM node, but a jQuery object -- this object contains both a reference to the actual DOM node ([0]), as well as a jquery object ([1]).
So to select the DOM node with $(this), you target the node: $(this)[0]. Then you can use .innerHTML() to grab the HTML contents of the node and do as you like.
Final result:
$(function () {
$('.onclick').click(function () {
$('#favorites').append( $(this)[0].innerHTML );
});
});

So the building blocks are not that complex, but I think you're a novice jQuery developer and so you may not be clear on the difference between jQuery and JS yet.
$(selector, context) allows us to create a jQuery collection for a CSS selector which is the child of a current context DOM node, though if you do not specify one there is an automatic one (which is document.body, I think). Various functions iterating over jQuery collections make the particular element available as this within the JavaScript. To get to the strong element from the .onclick element in the HTML fragment you need to travel up in the hierarchy, then to the appropriate element. Then, we can collect the text from the element. We can do this in either JS or jQuery.
To do this with simply jQuery:
// AP style title case, because Chicago is too crazy.
var to_title_case = (function () { // variable scope bracket
var lower_case = /\b(?:a|an|the|and|for|in|so|nor|to|at|of|up|but|on|yet|by|or)\b/i,
first_word = /^(\W*)(\w*)/,
last_word = /(\w*)(\W*)$/;
function capitalize(word) {
return word.slice(0, 1).toUpperCase() + word.slice(1).toLowerCase();
}
function capitalize_mid(word) {
return lower_case.exec(word) ? word.toLowerCase() : capitalize(word);
}
return function to_title_case(str) {
var prefix = first_word.exec(str),
str_minus_prefix = str.slice(prefix[0].length),
suffix = last_word.exec(str_minus_prefix),
center = str_minus_prefix.slice(0, -suffix[0].length);
return prefix[1] + capitalize(prefix[2]) + center.replace(/\w+/g, capitalize_mid)
+ capitalize(suffix[1]) + suffix[2];
};
})();
$(document).ready(function() {
$(".onclick").click(function () {
var text = $(this).parents('.ui-grid-a').find('.ui-block-a').text();
var html = '<div data-role="main"class="ui-content">'
+ '<div class="ui-grid-b"><div class="ui-block-a">'
+ to_title_case(text) + '</div><div class="ui-block-b">More Info</div>'
+ '<div class="ui-block-c">Unfavorite</div></div></div>';
$("#favorites").append(html);
});
});

Jquery hover event stuck on clone elements

I am creating an plugin with wordpress for the portfolio items. Everything works fine . But the issue is when i apply the filter the hover effect stopped working on the cloned items
also available JS FIDDLE
the jquery code is given below i tried
/* Scroll to Top Button */
jQuery(document).ready(function() {
// Animate Box Shadow on some elements
// Add the overlay. We don't need it in HTML so we create it here
// Clone portfolio items to get a second collection for Quicksand plugin
var $portfolioClone = jQuery(".rudra-portfolio").clone(true);
// Attempt to call Quicksand on every click event handler
jQuery(".rudra-portfolio-filter a").click(function(e) {
jQuery(".rudra-portfolio-filter li").removeClass("current");
// Get the class attribute value of the clicked link
var $filterClass = jQuery(this).parent().attr("class");
if ($filterClass == "all") {
var $filteredPortfolio = $portfolioClone.find("li");
} else {
var $filteredPortfolio = $portfolioClone.find("li[data-type~=" + $filterClass + "]");
}
// Call quicksand
jQuery("ul.rudra-portfolio").quicksand($filteredPortfolio, {
duration: 500,
easing: 'easeInOutQuad'
});
jQuery(this).parent().addClass("current");
// Prevent the browser jump to the link anchor
e.preventDefault();
})
jQuery(".port-li").click(function() {
jQuery(this).find('.content-wrapper').slideDown();
});
jQuery(".overeffect").mouseover(function() {
jQuery(this).find('.content-wrapper').slideDown();
});
jQuery("#portfolio-grid li").mouseleave(function() {
jQuery('.content-wrapper').slideUp(500);
});
});
hour effect is working fine for first and second time , but after that it stopped working .
Update
I also tried this Jquery clone

solved by me ..
i just need to use this
jQuery(document).on('hover',".overeffect",function(){
jQuery(this).find('.content-wrapper').slideDown();
});

Transfer data from one page to another jQuery Mobile

I using PhoneGap to create a Geolocation App following this excellent tutorial (link). Unfortunatelly, I'm having an issue that I can't figure out. The relevant parts that are giving me a headache are these:
//Section 1
$('#history').on('pageshow', function () {
tracks_recorded = window.localStorage.length;
$("#tracks_recorded").html("<strong>" + tracks_recorded + "</strong> workout(s) recorded");
$("#history_tracklist").empty();
for (i = 0; i < tracks_recorded; i++) {
$("#history_tracklist").append("<li><a href='#track_info' data-ajax='false'>" + window.localStorage.key(i) + "</a></li>");
}
$("#history_tracklist").listview('refresh');
});
//Section 2
$("#history_tracklist li a").on('click', function () {
$("#track_info").attr("track_id", $(this).text());
});
//Section 3
$('#track_info').on('pageshow', function () {
var key = $(this).attr("track_id");
$("#track_info div[data-role=header] h1").text(key);
var data = window.localStorage.getItem(key);
data = JSON.parse(data);
});
Section 1 works just fine, the data is stored, and the list is created without any issues. But then in Section 2 is when everything goes to hell. By clicking on the element, a new attribute (track_id) is supposed to be created, but it doesn't. Therefore, in Section 3, the "var key" won't get a value, and as a consequence, "var data" will be null also. As you can imagine, nothing works from there. What am I doing wrong here? I only included what I considered the relevant code, but if more is needed I'll do so. Thansk!

In section 2, I think you just need to delegate click handling to the "#history_tracklist" container, as follows :
$("#history_tracklist").on('click', "li a", function () {
$("#track_info").attr("track_id", $(this).text());
});
Without delegation you have a rule saying :
when any existing li a element within #history_tracklist is clicked execute my function
With delegation, you have a rule saying :
when any existing or future li a element within #history_tracklist is clicked execute my function

JScrollPane Plugin - Reinitialize on Collapse

I'm trying to get JScrollPane to reinitialize on expand/collapse of my accordion found here. You can demo the accordion by clicking on one of the parents (Stone Tiles, Stone Sinks, Stone Wall Clading, etc).
Right now I set it as a click event using the following JQuery...
var pane = $('.menuwrap')
pane.jScrollPane();
var api = pane.data('jsp');
var i = 1;
$("ul#widget-collapscat-5-top > li.collapsing").click(function() {
$(this).delay(3000);
api.reinitialise();
});
It seems to work when you click the parent the second time, but not the first. I have no idea why but I went into trying to edit the JS for the accordion so that I can add this function when the collapse is complete (as opposed to trying to do this click workaround). The collapse JS can be viewed here.
I tried to add the JS for the reinitialize function here, but I think I'm not doing something properly.
May you point me in the right direction?
Thanks!

The api.reinitialise() is working properly. What is happening is that it updates the size when you click, and at this moment the element is not expanded yet. You may notice that if you expand, colapse and expand again the same section, nothing happens. But if you expand one and then click another one, the ScrollPane will adjust to the size of the first expanded element.
You can solve this with events: place $(this).trigger('colapseComplete') when the colapse ends. Then you can use:
//Listening to the colapseComplete event we triggered above
$("#widget-collapscat-5-top > li.collapsing").on('colapseComplete', function() {
api.reinitialise();
});

Maybe you can alter the addExpandCollapse function to call the reinitialise function at the end of each of its click actions this way :
function addExpandCollapse(id, expandSym, collapseSym, accordion) {
jQuery('#' + id + ' .expand').live('click', function() {
if (accordion==1) {
var theDiv = jQuery(this).parent().parent().find('span.collapse').parent().find('div');
jQuery(theDiv).hide('normal');
jQuery(this).parent().parent().find('span.collapse').removeClass('collapse').addClass('expand');
createCookie(theDiv.attr('id'), 0, 7);
}
jQuery('#' + id + ' .expand .sym').html(expandSym);
expandCat(this, expandSym, collapseSym);
api.reinitialise(); // HERE
return false;
});
jQuery('#' + id + ' .collapse').live('click', function() {
collapseCat(this, expandSym, collapseSym);
api.reinitialise(); // and HERE
return false;
});
}
and to be on a safer side, make sure you have the var api = pane.data('jsp'); line before the above piece of code anywhere in the file.

JQuery Show/Hide Link

So here is my dilemma. Been trucking on this Jquery extreme code here and I need help telling if a certain link is showing or not. Here is what I have.
The toggles:
<span class="icon icon84"></span>
<span class="icon icon85"></span>
(notice the only thing that is different is the icon number) These need to toggle back and forth when someone clicks the #visbilitybutton. Not sure of the best way to do this and to capture what is selected as well.
The only code I have currently makes the toggle go one way, but doesn't go back when clicked again.
$(document).ready(function () {
$('#visbilitybutton').click(function() {
$(this).replaceWith('<span class="icon icon85"></span>');
});
});

First things first, you shouldn't have multiple identical id attributes on your page. Make visibilitybutton a class.
Anyways, you can use the jQuery toggle() function to specify what to do on each consecutive click:
$(".visibilitybutton").toggle(function(){
$(this)
.attr("title","Invisible")
.find("span").toggleClass("icon84 icon85");
}, function(){
$(this)
.attr("title","Visible")
.find("span").toggleClass("icon84 icon85");
});
If you want to be more efficient, you can do it all in one fell jQuery swoop like so, with some good techniques:
var vis = ["Invisible","Visible"];
$(".visibilitybutton").click(function(){
var i = 0;
$(this)
.attr("title",vis[i])
.find("span").toggleClass("icon84 icon85");
i = (i==0)?1:0;
});
Even more so would be to make a class that hides the element when added to it and shows it when you remove it (a classname with display:none applied in the CSS works fine):
$(".visibilitybutton").click(function(){
$(this)
.toggleClass("hide")
.find("span").toggleClass("icon84 icon85");
});

You need to have unique ids; therefore, you should select the items by class. You can use toggle() to handle the consecutive clicks, and you can use toggleClass() to handle the swapping of classes.
HTML:
<span class="icon icon84"></span>
<span class="icon icon85"></span>
Javascript:
$(document).ready(function () {
$('.button').toggle(function() {
var $button = $(this);
$button.prop("title","Invisible");
$button.find('.icon85').toggleClass('icon85', 'icon84');
}, function() {
var $button = $(this);
$button.prop("title","Visible");
$button.find('.icon85').toggleClass('icon84', 'icon85');
});
});

The id attribute is supposed to be unique to each element. Change the id attribute to the class attribute for each hyperlink.
Then, in your jQuery code, get the hyperlinks by their class name:
$('.visbilitybutton').click(function() {
// code goes here
});
In your event handler, you should use test the title attribute, like so:
$('.visibilitybutton').click(function() {
$this = $(this);
if ($this.attr("title") == "Visible")
$this.attr("title", "Invisible").find("span")
.removeClass("icon85").addClass("icon84");
else
$this.attr("title", "Visible").find("span")
.removeClass("icon84").addClass("icon85");
});
