Hide popover on body click only if already visible

Hiding a div (for example #popover) on click is easy:
$(document).ready(function() {
$("#trigger").click(function(e) {
$("#popover").toggle();
e.stopPropagation();
});
$(document).click(function(e) {
if (!$(e.target).is('#popover, #popover *')) {
$("#popover").hide();
}
});
});
But isn't this function fired every time the user uses a click? (Which does not make sense for me). Can I somehow limit this function to fire only if #popover is already visible?

In that case you can try using $(document).one(function(e) {...}); every time you show #example.
$(document).ready(function() {
var didBindToBody = false;
function closePopOverOnBodyClick() {
didBindToBody = true;
$(document).one('click', function(e) {
if (!$(e.target).is('#popover, #popover *')) {
$("#popover").hide();
}
else {
closePopOverOnBodyClick();
}
didBindToBody = false;
});
}
$("#trigger").click(function(e) {
$("#popover").toggle();
e.stopPropagation();
if (!didBindToBody && $("#popover").is(":visible")) {
closePopOverOnBodyClick();
}
});
closePopOverOnBodyClick();
});
DEMO

You could try something like
$(document).click(function(e) {
if (!$('#example').is(":visible")) {
return false;
} else if (!$(e.target).is('#popover, .login-panel *')) {
$("#popover").hide();
}
});
Or you could combine the two conditionals into one, just thought I'd keep it separate for readability and to make my suggestion easier to spot.

Bootstrap collapse - opening multiple accordions at the same time

I've got to a point where my accordions open up at the same time - see http://www.bootply.com/Go4t29rYyF
When you click on "tab1" all the "tab1s" open, when you click on "tab2" all the "tab2s" open - great! But I cant open "tab1s & tab2s" at the same time, it only works when I close one of the tabs first before opening another. The issue is with my js but cant work it out.
$(function () {
var $active = true;
$('.panel-title > a').click(function (e) {
e.preventDefault();
});
$('.number1-collapse').on('click', function () {
if (!$active) {
$active = true;
$('.panel-title > a').attr('data-toggle', 'collapse');
$('.number1').collapse('hide');
} else {
$active = false;
$('.number1').collapse('show');
$('.panel-title > a').attr('data-toggle', '');
}
});
$('.number2-collapse').on('click', function () {
if (!$active) {
$active = true;
$('.panel-title > a').attr('data-toggle', 'collapse');
$('.number2').collapse('hide');
} else {
$active = false;
$('.number2').collapse('show');
$('.panel-title > a').attr('data-toggle', '');
}
});
});

I've tidied up your code and changed to using the toggle method instead of having various flags. The problem is that you are sharing the active flag between them. Here is the improved code and Bootply:
$(function () {
$('.panel-title > a').click(function (e) {
e.preventDefault();
});
$('.number1-collapse').on('click', function () {
$('.number1').collapse('toggle');
});
$('.number2-collapse').on('click', function () {
$('.number2').collapse('toggle');
});
});

You may want to specify which elements you are effecting in your function using the event parameter
Example:
$('.number2-collapse').on('click', function (event) {
var panelTitle = $(event.currentTarget).find('.panel-title > a');
var number = $(event.currentTarget).find('.number2');
if (!$active) {
$active = true;
$(panelTitle).attr('data-toggle', 'collapse');
$(number).collapse('hide');
} else {
$active = false;
$(number).collapse('show');
$(panelTitle).attr('data-toggle', '');
}
});
This is an example. You may need to alter this code for it to work in your situation

Remove option with value = MRW if I checkbox if checked

I'm trying to remove a option with value equal to MRW if #natural_person_lives_in_ccs_0 is checked but if I unchecked the checkbox then the SELECT should be as it was by default meaning same options. This is what I did:
$(document).ready(function(){
var lives_in_css = $('#natural_person_lives_in_ccs_0').is(':checked');
if (lives_in_css) {
$(".shipping_from option[value='MRW']").remove();
} else {
$(".shipping_from").append('<option value="MRW">Option1</option>');
}
});
But it's not working since Option1 is added by default and I don't know how to write this. I think to use .toggle() but don't know if it's the right one. I leave a Plunker here for testing. Any help on this?
Steps:
Check Yes option value=MRW should be removed
Remove the check from Yes option value=MRW as by default (same position)

Try to use the .change() function to accomplish your task here,
$('#natural_person_lives_in_ccs_0').click(function () {
var elem = $(".shipping_from option[value='MRW']");
if (this.checked) {
elem.remove();
} else if (elem.length == 0) {
$(".shipping_from").prepend('<option value="MRW">Option1</option>');
}
});
DEMO
The best way would be,
$('#natural_person_lives_in_ccs_0').click(function () {
$(".shipping_from option[value='MRW']").toggle(!this.checked);
$(".shipping_from option:eq(" + ((this.checked) ? 1 : 0) + ")").prop('selected', true);
});
DEMO

Write your script like bellow.
var showOptionsAcorrdingCheckbox = function(){
var lives_in_css = $('#natural_person_lives_in_ccs_0').is(':checked');
if (lives_in_css) {
$(".shipping_from option[value='MRW']").remove();
} else {
$(".shipping_from").append('<option value="MRW">Option1</option>');
}
}
$(document).ready(function(){
$(':checkbox').change(showOptionsAcorrdingCheckbox);
});

DEMO
code:
$(document).ready(function(){
$(document).on('change', '#natural_person_lives_in_ccs_0', function(){
if($(this).is(':checked'))
{
$(".shipping_from option[value='MRW']").remove();
}
else
{
$(".shipping_from").append('<option value="MRW">Option1</option>');
}
});
});

How do I hide and unhide a DIV on my web page based on a checkbox check?

I tried this but it isn't working:
$('cbxShowNotifications').click(function()
{
var tview = $('#treeview');
if ($(this).checked)
{
tview.show();
}
else
{
tview.hide();
}
});
EDIT -
Fixed a few things but I'm still unable to show the DIV AFTER I hide it:
$('#cbxShowNotifications').on('click', (function()
{
var tview = $('#treeview');
if ($(this).checked)
{
tview.show();
}
else
{
tview.hide();
}
}));

change ($(this).checked) to ($(this).is(':checked'))

You have some syntax issues, and you should monitor the change event on checkboxes:
$('#cbxShowNotifications').on('change', function () {
var tview = $('#treeview');
if ($(this).prop('checked')) {
tview.show();
} else {
tview.hide();
}
});
NOTE: You can set the initial state by the trigger of the change event:
$('#cbxShowNotifications').trigger('change');

You can do it like this:
$('#treeview').on({
'change': function(){
if ($('div').css('display') == 'block') {
$('div').hide();
} else {
$('div').show();
}
}
})
jsfiddle: http://jsfiddle.net/PWAwz/

is this what you're searching? I wrote the codes below you can check they are working in example too. http://jsfiddle.net/jquerybyexample/xe7aL/
$(document).ready(function(){
$('.checkbox1').change(function(){
$('.tview').toggle('fast');
});
});

I know your question is related to jQuery, but if the purpose is purely presentational, perhaps you can consider a CSS way to accomplish the same thing:
#treeview {
display: none
}
#cbxShowNotifications:checked ~ #treeview {
display: block
}

How to untoggle a dropdown by clicking elsewhere in the page - stopPropagation?

I wonder if anyone can help to finally resolve an issue I brought up on SO a while back.
I am unable to untoggle these dropdown menus by clicking outside of the button, or anywhere else on the page.
Please see this jsFiddle.
I've seen folks using stopPropagaton() but am unsure how to apply it here.
Any ideas how to do this?
My toggling code:
var cur = null;
$(".toggle").click(function(e){
$('#nav ul:visible').hide();
if(cur == null || cur.currentTarget != e.currentTarget)
{
if(cur != null)
{
$(cur.currentTarget)
.children('a:first').children('span').removeClass('fc-state-active');
}
cur = e;
$(cur.currentTarget)
.children('a:first').children('span').addClass('fc-state-active');
$(cur.currentTarget)
.children('ul').show();
}
else
{
$(cur.currentTarget)
.children('a:first').children('span').removeClass('fc-state-active');
cur = null;
}
});

I believe the following should work for you. This utilizes jQuery's focusout() function:
$(".toggle").click(function(){
$('#nav ul:visible').hide();
$('span.fc-state-active').removeClass('fc-state-active');
$(this).children('a:first').children('span').addClass('fc-state-active');
$(this).children('ul').show();
}).focusout(function(){
$('#nav ul:visible').hide();
$('span.fc-state-active').removeClass('fc-state-active');
});
And here's an updated fiddle: jSFiddle
EDIT: The following works in FF & Chrome
New Fiddle: jsFiddle
$(".toggle").click(function(){
$('#nav ul:visible').hide();
$('span.fc-state-active').removeClass('fc-state-active');
$(this).children('a:first').children('span').addClass('fc-state-active');
$(this).children('ul').show();
hide = false;
});
$(document).click(function(){
if(hide){
$('#nav ul:visible').hide();
$('span.fc-state-active').removeClass('fc-state-active');
}
hide = true;
});
Reason: $(document).click() is called after $(".toggle").click()
EDIT 2: The working fiddle can be found here: jSFiddle
var hide;
$(".toggle").click(function(){
var active_span = $(this).children('a:first').children('span');
var active_ul = $(this).children('ul');
$(active_span).toggleClass('fc-state-active');
$("span.fc-state-active").not(active_span).removeClass('fc-state-active');
$(active_ul).toggle();
$("#nav ul:visible").not(active_ul).hide();
hide = false;
});
$(document).click(function(){
if(hide){
$('#nav ul:visible').hide();
$('span.fc-state-active').removeClass('fc-state-active');
}
hide = true;
});
