jQuery onclick function: Undefined is not a function

Edit: I guess part of this is an issue of me being inexperienced with Drupal. I added a javascript file to site.info, so that it will be added to every page. This is all the file contains:
(function ($){
$("#ctl00_btnSearch001").on("click", function(){
var searchVal = $("#ctl00_txtSearch").val();
window.location.href = "http://www.mywebsite.org/search/?sa=Search&q=" + searchVal;
});
})(jQuery);
When the site loads, it gets compiled into this larger script, which looks like this in the debugger:
(function ($) {
Drupal.behaviors.titlebar = {
init: function(context, settings) {
// Using percentage font size to easily increase/decrease page font size
var baseFontSize = 100;
$('.pgc-font-size a').click(function() {
if($(this).hasClass('increase')) {
if(baseFontSize < 150)
baseFontSize += 20;
$('.pg-content-body p').css('font-size', baseFontSize+'%');
} else {
if(baseFontSize > 70)
baseFontSize -= 10;
$('.pg-content-body p').css('font-size', baseFontSize+'%');
}
});
// Print button
$('.pgc-print a').click(function() {
window.print();
})
}
};
}(jQuery));
// There's a problem with our jQuery loading before the ingested site's
// jQuery which is causing jQuery plugins to break (the "once" plugin in this case).
// I'm using this workaround for now
jQuery(function() {
Drupal.behaviors.titlebar.init();
});;
(function ($) {
Drupal.behaviors.giftTypes = {
init: function() {
// Gift details accordion
$('.pg-gift-details .accordion-items').css('display', 'none');
$('.pg-gift-details .accordion-switch').click(function(){
if($(this).hasClass('open')) {
$(this).find('span').removeClass('icon-arrow-up').addClass('icon-arrow-down');
$('.pg-gift-details .accordion-items').slideUp('slow');
$(this).html($(this).html().replace('Hide', 'Show More'));
$(this).removeClass('open');
} else {
$(this).find('span').removeClass('icon-arrow-down').addClass('icon-arrow-up');
$('.pg-gift-details .accordion-items').slideDown('slow');
$(this).html($(this).html().replace('Show More', 'Hide'));
$(this).addClass('open');
}
})
}
}
}(jQuery));
// There's a problem with our jQuery loading before the ingested site's
// jQuery which is causing jQuery plugins to break (the "once" plugin in this case).
// I'm using this workaround for now
jQuery(function() {
Drupal.behaviors.giftTypes.init();
});;
(function ($){
$("#ctl00_btnSearch001").on("click", function(){
var searchVal = $("#ctl00_txtSearch").val();
alert(searchVal);
window.location.href = "http://www.mywebsite.org/search/?sa=Search&q=" + searchVal;
});
})(jQuery);
;
You can see my little script at the bottom there. It says there's something wrong with the first line, but I'm not sure what the problem is. What change would I need to make to my javascript file to make sure it compiles right?
I'm probably overlooking a really simple type, but I can't see what's wrong with my jQuery.
This is the part that's not working:
(function ($){
$("#ctl00_btnSearch001").on("click", function(){
var searchVal = $("#ctl00_txtSearch").val();
window.location.href = "http://www.website.org/search/?sa=Search&q=" + searchVal;
});
})(jQuery);
I have jQuery on my site, I know I do because this it's used earlier in the code with no problem. The error is showing in the debugger on the first line, '$("#ct100_btnSearch001").on("click", function(){ '. Here is a larger section of the script page:
(function($) {
Drupal.behaviors.giftTypes = {
init: function() {
// Gift details accordion
$('.pg-gift-details .accordion-items').css('display', 'none');
$('.pg-gift-details .accordion-switch').click(function() {
if ($(this).hasClass('open')) {
$(this).find('span').removeClass('icon-arrow-up').addClass('icon-arrow-down');
$('.pg-gift-details .accordion-items').slideUp('slow');
$(this).html($(this).html().replace('Hide', 'Show More'));
$(this).removeClass('open');
} else {
$(this).find('span').removeClass('icon-arrow-down').addClass('icon-arrow-up');
$('.pg-gift-details .accordion-items').slideDown('slow');
$(this).html($(this).html().replace('Show More', 'Hide'));
$(this).addClass('open');
}
})
}
}
}(jQuery));
jQuery(function() {
Drupal.behaviors.giftTypes.init();
});;
(function($) {
$("#ctl00_btnSearch001").on("click", function() {
var searchVal = $("#ctl00_txtSearch").val();
alert(searchVal);
window.location.href = "http://www.mywebsite.org/search/?sa=Search&q=" + searchVal;
});
})(jQuery);;

Try to install jQuery update Module.
If you are using Drupal 6, you are not be able to use on function.
One option is to include your custom version of jQuery in your page.tpl.php, another option (not recommended) is to use live, but now is deprecated.

You can bind a function to an event use two way:
1.use bind() method and the event name as the first argument
$( "#foo" ).bind( "click", function() {
alert( "User clicked on 'foo.'" );
});
or
2.just use the event method
$( "#foo" ).click( function() {
alert( "User clicked on 'foo.'" );
});
The problem of your code is that there isn't a on event.
ref http://api.jquery.com/category/events/mouse-events/

If ctl00_btnSearch001 is a correct id for what ever you are trying to click. Try changing it to this:
(function ($){
$(document).on("click", "#ctl00_btnSearch001", function(){
var searchVal = $("#ctl00_txtSearch").val();
window.location.href = "http://www.mywebsite.org/search/?sa=Search&q=" + searchVal;
});
})(jQuery);

Ajax + browser backbutton = checkbox not working

I have a content page which is loaded via Ajax with a checkbox on it. The checkboxes works as it should when I click the normal menu buttons on my webpage to get to the content. But when I go to another page and use the back button to get back to the page which has the checkboxes, the checkboxes stop working.
html:
<div id="filters">
<ul id="filters-background">
<li id="option-type">Filter Options</li>
<li class="wave2"><label for="white">White<input type="checkbox" name="white" value=".White" id="white"></label></li>
<li class="wave2"><label for="blue">Blue<input type="checkbox" name="blue" value=".Blue" id="blue"></label></li>
</ul>
</div>
<script type="text/javascript">
OnSort();
</script>
js:
function OnSort(e) {
console.log('aaa');
// filter button click
var filterCheckboxes = $('#filters input');
var filters = [];
filterCheckboxes.change(function() {
console.log('clicked checkbox');
filterCheckboxes.filter(':checked').each(function() {
console.log('working');
filters.push( this.value );
});
});
}
If you look at the above code, the console will output 'aaa' when I click on the back button but if I test a checkbox it will not output 'clicked checkbox' in the console. How can I make it so the checkboxes will keep working even after I use the browser back button?
Maybe relevant PageLoad and Backbutton Ajax code:
function OnLoadPage(e) {
e.preventDefault();
var pageurl = $(this).data('url');
$.ajax({
type: 'GET',
url: pageurl,
success: function(data) {
$('#content').html(data['content']); // update content
if(data['menu']) { // update menu
$('#menu').html(data['menu']);
}
else {
$('#menu').html('');
}
// update url
window.history.pushState({path:pageurl}, '', pageurl);
},
error: function(response) {
alert('ERROR:' + response.responseText);
}
});
}
function InitOverrideBrowserBackButton() {
// override the back button to get the ajax content without page reload
$(window).bind('popstate', function() {
$.ajax({url:location.pathname+'?rel=tab', success: function(data){
$('#content').html(data['content']); // update content
if(data['menu']) { // update menu
$('#menu').html(data['menu']);
}
else {
$('#menu').html('');
}
}});
});
}
I've also tried:
$(document).on('click', '#filters input', function() {
console.log('clicked checkbox');
filterCheckboxes.filter(':checked').each(function() {
console.log('working');
filters.push( this.value );
});
});
Which will output 'aaa' and 'clicked checkbox' but not 'working'.

Figured it out with help from others on StackOverflow. Here's the answer:
function OnSort(e) {
console.log('aaa');
// filter button click
var filters = [];
$(document).on('click', '#filters input', function() {
console.log('clicked checkbox');
$('#filters input', document).filter(':checked').each(function() {
console.log('working');
filters.push( this.value );
});
});
}

Twitter bootstrap:Popop are not showing up on first click but show up on second click

Here is my code. Please help me
$(document).ready(function(){
$(document).delegate(".view","click",function(){
var id = $(this).attr("id");
alert(id);
$("#"+id).popover({
html : true,
content: function() {
return $("#"+id+"tt").html();
},
title: function() {
return $('#popoverTitle').html();
}
});
alert("thisa");
});
});

Try replacing the function .delegate() by .on(), this function has been superseded in the last versions of Jquery.
jQuery 1.4.3+
$( elements ).delegate( selector, events, data, handler );
jQuery 1.7+
$( elements ).on( events, selector, data, handler );
The code would be:
$(document).ready(function(){
$(document).on("click",".view",function(){
var id = $(this).attr("id");
alert(id);
$("#"+id).popover({
html : true,
content: function() {
return $("#"+id+"tt").html();
},
title: function() {
return $('#popoverTitle').html();
}
});
alert("thisa");
});
});

Try doing this way..
$('.view')
.popover({trigger: 'manual'})
.click(function() {
if($(this).hasClass('pop')) {
$(this)
.popover('hide')
.removeClass('pop');
} else {
var id = $(this).attr("id");
var title = $('#popoverTitle').html();
var response = $("#"+id+"tt").html();
$(this)
.attr({'title': title, 'data-content': response})
.popover('show')
.addClass('pop');
}
});

Use the same button to trigger two different JQuery events

I am trying to use the same button to trigger an ajax call to add a database entry if it is clicked and then trigger a different ajax call to remove the entry it is clicked again.
I have tried using toggleClass and although the button class does change and it's appearance changes accordingly the function still thinks it has the old class name.
$(document).ready(function() {
$(".selected").on("click", function() {
$(this).text(function (i, oldText) {
return $.trim(oldText) == 'Use Image' ? 'Selected' : 'Use Image';
});
$(this).toggleClass('selected selected_btn');
});
$(".selected").on("click", function() {
alert('selected');
});
$(".selected_btn").on("click", function() {
alert('de selected');
});
});
With the present code the alert is always 'selected'.

$(document).ready(function() {
$(".selected_btn").on("click", function() {
$(this).text(function (i, oldText) {
return $.trim(oldText) == 'Use Image' ? 'Selected' : 'Use Image';
});
$(this).toggleClass('selected');
if($(this).hasClass("selected"))
alert("Selected")
else
alert("de-Selected")
});
});
here is a fiddle:
http://fiddle.jshell.net/prollygeek/3LLN2/

Here is a simple and readable example on how to do this:
$(document).ready(function() {
$('.select-img').on('click', function(){
var $el = $(this);
var isSelected = $el.attr('data-selected');
if( isSelected != 'true' ){
firstFn();
$el.html('Use Image').attr('data-selected', true)
}else{
secondFn();
$el.html('Select').attr('data-selected', false)
}
})
var firstFn = function(){
alert('first thing to do');
}
var secondFn = function(){
alert('second thing to do');
}
})
Demo

Use *Class functions:
hasClass
removeClass
addClass
Working code:
$("a").on("click", function() {
if($(this).hasClass("bob")) {
// do delete
alert("delete");
$(this).removeClass("bob");
} else {
// do insert
alert("insert");
$(this).addClass("bob");
}
});
Demo

$(".selected").on("click", function() {
alert('selected');
});
Overrides the event you put on the beginning of the document.ready, I think.
(might not be true, but I think it is)

Hover on dynamic link generated

I want to create a hover similar to the example here in the jQuery. But the link is dynamically generated so I'm really having a hard time figuring this out.
I tried this:
$(document).ready( function() {
$('a.g-tabs').on('hover', 'a', function() {
$( this ).append( $('<i class="icon-clear-remove" onClick="tabRemove();"></i>') );
},
function() {
$( this ).find( ".icon-clear-remove:last" ).remove();
});
});
But its not working. Seems like my selector is the problem. How can I select it properly?
UPDATE:
This JS is handles for the view to not refresh if the tab is created:
$(document).on('submit','#pop-form', function(e) {
// make an ajax request
$.post('../admin/FLT_add_tab.do',
$('#pop-form').serialize(),
function( data ) {
// if data from the database is empty string
if( $.trim( data ).length != 0 ) {
// hide popover
$('#popover').popover('hide');
//append new tab and new tab content
var id = $(".nav-tabs").children().length - 1;
$('#popover').closest('li').before('<li>' + data + '</li>');
$('.tab-content').append('<div class="tab-pane" id="tab_' + id + '"> <c:import url="flt-pis.html"></c:import> </div>');
} else {
// error handling later here
}
}
);
e.preventDefault();
});
Not this one is the HTML that handles the tabs if the user goes to this page in first hand:
<!-- Other tabs from the database -->
<c:forEach var="tabNames" items="${ allTabs }">
<li> ${ tabNames.key }</li>
</c:forEach>
<!-- Add new tab -->
<li>New <i class="icon-plus-sign"></i></li>
As requested the server side code:
#ResponseBody
#RequestMapping( value = "/admin/FLT_add_tab", method = RequestMethod.POST )
public String createNewTab( #RequestParam
String newTab, HttpServletRequest request )
{
HttpSession session = request.getSession();
String returnVal = Credentials.checkSession( session );
if( returnVal != null )
{
return returnVal;
}
String tabName = null;
try
{
DataSource dataSource = DatabaseCommunication.getInstance().getDataSource();
QuestionnaireDAO qDAO = new QuestionnaireDAO( dataSource );
if( qDAO.getTabName( 0, newTab ) == null )
{
qDAO.insertQtab( newTab );
tabName = newTab;
}
}
catch( Exception e )
{
// no logger yet
e.printStackTrace();
}
return tabName;
}

If it is dynamically created the you have to use the delegate
$(document).on('mouseenter', 'a.g-tabs', function() {
$( this ).append( $('<i class="icon-clear-remove" onClick="tabRemove();"></i>') );
});
$(document).on('mouseleave', 'a.g-tabs', function() {
$( this ).find( ".icon-clear-remove:last" ).remove();
});

try this code
$('a.g-tabs').on({
mouseenter: function() {
$( this ).append( $('<i class="icon-clear-remove" onClick="tabRemove();"></i>') );
},
mouseleave: function() {
$( this ).find( ".icon-clear-remove:last" ).remove();
}
}, "a");
this code from Is it possible to use jQuery .on and hover

use CSS.
.g-tabs a>.icon-clear-remove
{
display:none;
}
.g-tabs a:hover>.icon-clear-remove
{
display:inline-block;
}
E > F Matches any F element that is a child of an element E.
E:hover Matches E during user hovers E.
So, E:hover>F means that while user hovers E, apply rule to F.
