I've created custom widget by extending jQuery UI's Menu. It's basically needed to work with <select> HTML element like ui.selectmenu does, but display options in submenus:
$.widget("market.myMenu",$.ui.menu, {
// ...
_attachEvents: function(){
var self = this;
// menu is initially hidden
self.menuWrapper.hide();
self.button.on('click', function(){
if (self.originalSelect.is(':disabled')) {
self.disable();
} else {
self.menuWrapper.toggle();
}
return false;
});
$(document).on('click', function(){
self.menuWrapper.hide();
});
},
//...
}
}
The problem arise when this widget attached to multiple elements like:
someSelect.myMenu();
//...
anotherSelect.myMenu();
The problem is listed in the title and you can see it in _attachEvents() method:
when user clicks on someSelect it opens as should
then user clicks on anotherSelect it also opens
someSelect after step 2 should be closed, but it's not.
So how to check for such a case and fix this issue ?
EDIT:
this.originalSelect is <select> HTML element
this.button is div element. on which selected option text is displayed (basically same thing as ui.selectmenu does);
You can use a class to keep track of the state of your menus and use it to target instances that are opened. Something like this for example:
_attachEvents: function(){
var self = this;
// menu is initially hidden
self.menuWrapper.hide();
self.button.on('click', function(){
if (self.originalSelect.is(':disabled')) {
self.disable();
} else {
// before you open a menu, you close the opened ones
$('menu-opened').each(function(){
$(this).myMenu('instance').hideWrapper();
});
self.menuWrapper.toggleClass('menu-opened');
self.menuWrapper.toggle();
}
return false;
});
$(document).on('click', function(){
self.menuWrapper.hide();
});
},
hideWrapper: function(){
var self = this;
self.menuWrapper.hide();
self.menuWrapper.removeClass('menu-opened');
}
I've found solution. It's based upon Julien Grégoire proposal to use css marker class.
What I'm doing is adding class ui-mymenu-wrap to self.menuWrapper element. So all widgets have those identifier. The next thing I do is after clicking on one widget I'm closing all others menus and then open/close widget on which click was made.
_attachEvents: function(){
var self = this;
// menu is initially hidden
self.menuWrapper.hide();
self.button.on('click', function(event){
if (self.originalSelect.is(':disabled')) {
self.disable();
} else {
// hide all opened menus
$('.ui-mymenu-wrap').not(self.menuWrapper).hide();
self.menuWrapper.toggle();
}
return false;
});
$(document).on('click', function(){
self.menuWrapper.hide();
});
},

Here's my function,
$(document).ready(function () {
$('.a').click(function () {
var here = $(this).next('.b');
if (here.is(":visible")) {
here.hide();
} else {
here.show();
}
return false;
});
});
So, whenever I click the button it opens a small tab on same webpage & whenever I click it again it closes it. But once I open the tab I can't close it by just clicking somewhere on webpage apart from tab. I have to click the button again to close it.
How can I close tab just by clicking somewhere on webpage also by on the button?
I end up searching for this on almost every project, so I made this plugin:
jQuery.fn.clickOutside = function(callback){
var $me = this;
$(document).mouseup(function(e) {
if ( !$me.is(e.target) && $me.has(e.target).length === 0 ) {
callback.apply($me);
}
});
};
It takes a callback function and passes your original selector, so you can do this:
$('[selector]').clickOutside(function(){
$(this).removeClass('active'); // or `$(this).hide()`, if you must
});
Nice, chainable, elegant code.
On document click, the closest helps to check whether the tab has been clicked or not:
$(document).click(function (e) {
if($('.b').is(':visible')&&!$(e.target).closest('.b').length){
$('.b').hide();
}
});
You want to check for a click on the body :
$("body").click(function(e) {
if(e.target.id !== 'menu'){
$("#menu").hide();
}
});
menu would be the id of the menu.
If the body is clicked and the id of the div clicked doesn't equal that of the menu, then it closes.
Check this implementation
jQuery(document).ready(function() {
$(document).on('click','body, #btn',function(ev){
ev.stopPropagation()
if(ev.target.id== "btn"){
if($('#modal').is(':visible')) {
$('#modal').fadeOut();
} else{
$('#modal').fadeIn();
}
} else {
$('#modal').fadeOut();
}
});
});
html, body {
height: 100%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="btn">
Click Me!
</button>
<div id="modal" style="background-color:red;display:none;">
BLA BLA BLA
</div>
To check if the clicked element is outside of a given container, i.e. a menu, we can simply check if the event target is a child of the container. Using JQuery -
$('body').click(function(e) {
if ( 0 === $(e.target).parents('#container-id').length ) {
/// clicked outside -> do action
}
})
you have to add a click listener to the parent element, like here:
$('.parent-div').click(function() {
//Hide the menus if visible
});
Also because click events bubbled up from child to the parent,
you can exclude the click on the child element to get bubbled up and count as the parent click too. you can achieve this like below:
//disable click event on child element
$('.child-div').click(function(event){
event.stopPropagation();
});
I have having a little trouble with the slideToggle when I have a link inside of the slideup panel. What I am trying to do is have the ability to press a button and a div will slide up and display related posts and once you press another or the related project button on the page it will close the toggle and reveal another effect that I am using (100% width and heigh popup). The script I am using works perfect but I am running into one problem. When I click a related post inside of the slideToggle it causes the div to slide down instead of going to the page that represents the link.
Here is my code below and an example http://jsfiddle.net/K8vBg/15/.
$(document).ready(function(){
// build a variable to target the #menu div
var menu = $('#menu')
// bind a click function to the menu-trigger
$('#menu-trigger').click(function(event){
event.preventDefault();
event.stopPropagation();
// if the menu is visible slide it up
if (menu.is(":visible"))
{
menu.slideUp(1000);
}
// otherwise, slide the menu down
else
{
menu.slideDown(400);
}
});
$(document).not('.projectHolder-small,#projectSpecs').click(function(event) {
event.preventDefault();
if (menu.is(":visible"))
{
menu.slideUp(400);
}
});
})
If I change .projectHolder-small,#projectSpecs in the .not function to just read #menu then I am able to click the link inside of the panel but the panel will not slideDown when I click another button on the page. The popup from #project specs will just go over the panel instead of closing it.
Is there something I am missing in my script?
Thank you
Try changing the $(document).not().click() to:
$(document).click(function(event){
if(!$(event.target).closest('.projectHolder-small,#projectSpecs').length){
if (menu.is(":visible")){
menu.slideUp(400);
}
}
});
I am using closest() instead of the usual is(), so that even clicking on the children elements of '.projectHolder-small,#projectSpecs' the panel won't close.
I rewrote the script to the following and it works perfect
$(document).ready(function () {
var $frm = $('#menu').hide();
var $bts = $("#menu-trigger").on('click', function () {
var $this = $(this)
$bts.filter(".selected").not(this).removeClass('selected');
$this.toggleClass('selected');
if ($this.hasClass('selected') && $frm.is(':visible')) {
$frm.stop(true, true).slideUp(function () {
$(this).slideDown()
});
} else {
$frm.stop(true, true).slideToggle();
}
});
$bts.filter('.selected').click();
$("#projectSpecs, #menuButton").click(function () {
$bts.filter(".selected").removeClass('selected');
$frm.slideUp();
});
});
The Fiddle: http://jsfiddle.net/bscn3/
Scenario:
I want to use nested toggles inside tabbed containers, as in the fiddle.
My Issue:
When I click on Main Toggle ("Toggle 1") or ("Toggle 2"), the inner contents display.
But it closes if I click on anything inside. For Eg. If I click on Toggle 2, and if I click on Tab 1 -> Nested Toggle 1, Toggle 2 itself closes.
I want it to remain open.
My Guess:
The JQuery working closes the toggle if anything related to the Toggle (Even text content) is clicked.
My Need:
I want the Toggle to close only if those rectangular headers are clicked.
Also, if you can help clean up the code in such a way, that I don't need to write separate JS to make inner nested Toggles work independently of its parent or children toggles, it would great.
Currently I have two Toggle JS Functions written for the two toggles in example.
//TOGGLE
$('.toggle-view li').click(function () {
var text = $(this).children('.t');
if (text.is(':hidden')) {
text.slideDown('fast');
$(this).children('.toggle').addClass('tactive');
} else {
text.slideUp('fast');
$(this).children('.toggle').removeClass('tactive');
}
});
//TOGGLE L2
$('.toggle-view2 li').click(function () {
var text2 = $(this).children('.t2');
if (text2.is(':hidden')) {
text2.slideDown('fast');
$(this).children('.toggle2').addClass('tactive2');
} else {
text2.slideUp('fast');
$(this).children('.toggle2').removeClass('tactive2');
}
});
P.S. I haven't written the JS Code, I am using someone's template.
Thanks! :)
Seems like a pretty simple solution...
It's happening because the toggle currently activates whenever you click anythin inside of the li element (which includes the other toggle elements: .toggle2).
The solution therefore is to make it only activate the toggle when the .toggle/h6 element is clicked and change $(this).children(...) to $(this).siblings(...)
You can use the following as things are (same changes in TOGGLE and TOGGLE L2):
//TOGGLE
$('.toggle-view li .toggle').click(function () { // Changed selector
var text = $(this).siblings('.t'); // Changed to .siblings(...)
if (text.is(':hidden')) {
text.slideDown('fast');
$(this).addClass('tactive'); // Removed .children(...)
} else {
text.slideUp('fast');
$(this).removeClass('tactive'); // Removed .children(...)
}
});
//TOGGLE L2
$('.toggle-view2 li .toggle2').click(function () {
var text2 = $(this).siblings('.t2');
if (text2.is(':hidden')) {
text2.slideDown('fast');
$(this).addClass('tactive2');
} else {
text2.slideUp('fast');
$(this).removeClass('tactive2');
}
});
OR
Just use the first section...
//TOGGLE
$('.toggle-view li .toggle').click(function () {
var text = $(this).siblings('.t');
if (text.is(':hidden')) {
text.slideDown('fast');
$(this).addClass('tactive');
} else {
text.slideUp('fast');
$(this).removeClass('tactive');
}
});
and rename all of the .t2, .toggle2 etc. in your html to the same as the first one (i.e. .t2 becomes .t)
use event.stopPropagation()
i have updated jsfiddle
$('.toggle-view2 li').click(function (event) {
event.stopPropagation();
var text2 = $(this).children('.t2');
if (text2.is(':hidden')) {
text2.slideDown('fast');
$(this).children('.toggle2').addClass('tactive2');
} else {
text2.slideUp('fast');
$(this).children('.toggle2').removeClass('tactive2');
}
});
I can't manage to find out how to initiate a click event by a user clicking on a dropdown. I want to populate the dropdown ONLY if the user clicks the dropdown which will be rare. In addition, it depends on several other values selected on the page. So basically, how do I fire off an event if a user just simply clicks on the dropdown to see the options.
I've tried, $('select').click but to no avail.
It works if you don't have any options. But if there are current options, no luck.
Try using the focus event instead, that way the select will be populated even when targeted using the keyboard.
$('select').on('focus', function() {
var $this = $(this);
if ($this.children().length == 1) {
$this.append('<option value="1">1</option><option value="2">2</option>');
}
});
View simple demo.
UPDATE
Here is a new version that uses unbind to only fire the event handler once. This way you are able to use your alert without adding any option elements to change the outcome of the condition as the previous solution required.
$('select').on('focus', function() {
var $this = $(this);
// run your alert here if it´s necessary
alert('Focused for the first time :)');
// add the new option elements
$this.append('<option value="1">1</option><option value="2">2</option>');
// unbind the event to prevent it from being triggered again
$this.unbind('focus');
});
Hope that is what you are looking for.
It should work. Here I've done it and its working.
$("select").on("click", function() {
$(this).append("<option>1</option><option>2</option>");
});
Updated: http://jsfiddle.net/paska/bGTug/2/
New code:
var loaded = false;
$("select").on("click", function() {
if (loaded)
return;
$(this).append("<option>1</option><option>2</option>");
loaded = true;
});
Getting the dropdown to automatically open after the click is trickier:
// Mousedown is used so IE works
$('#select_id').on('focus mousedown', function (e) {
var data;
$(this).off('focus mousedown');
$.ajax({async: false,
type: 'GET',
url: 'url that returns the options',
success: function (d) { data = d; }
});
$(this).find('option').remove().end().append(data);
// Prevent IE hang by waiting awhile
var t = new Date().getTime(); while(new Date().getTime() < t + 200) {}
return true;
});
I'm trying to write a web app which replaces the context menu (right-click menu) with my own customized ones. I want it so that when the user clicks on a table row, they get one certain context menu and when they click on the background of the page, they get a different one.
I have already written the menus and gotten them working. The problem comes in when trying to figure out how to get the background's menu to show ONLY when clicking on the background and how to get the table row's menu to show when that is clicked.
I tried using document.body.oncontextmenu for the body and and setting the oncontextmenu function for each table row, but the body's oncontextmenu function overrides the row's so I get the wrong menu. The menu for the table rows DOES work if I stop using the body's menu, so that's not the issue.
I could be using the wrong events, so is there a different event for just the background (and not the elements on top of the background)? Or a way to "prioritize" the events so the table row's function takes precedence?
This is how the code looks:
var tableMenu;
var bodyMenu;
window.onload = function()
{
bodyMenu = new rightClickMenu("bodyMenu");
document.body.oncontextmenu = function() { bodyMenu.show(); tableMenu.hide(); }
bodyMenu.add("Add Entry", function()
{
alert("ADD");
});
tableMenu = new rightClickMenu("tableMenu", "tblSims");
simRows = getElementsByClassName("trSimRow");
for (var i in simRows)
simRows[i].oncontextmenu = function() { tableMenu.show(this.id.substring(2)); bodyMenu.hide(); }
tableMenu.add("Delete Entry", function(mac)
{
alert("DELETE");
});
document.body.onclick = function()
{
bodyMenu.hide();
tableMenu.hide();
};
}
You can capture the target element, e.g.:
$('*').click(function(e) {
alert(e.target);
alert(e.target.tagName);
if(e.target.tagName == 'html') {
// show background menu
}
});
You have to work with the Javascript Event Propagation model. What happens is that your click event is automatically passed down the layers of objects on a page that have been registered as event listeners, unless you explicitly tell it to stop, try something like this:
function setupClickHandlers()
{
document.getElementsByTagName('body')[0].onclick = doBodyMenu;
document.getElementById('tableID').onclick = doTableMenu;
}
function doBodyMenu()
{
//do whatever it does
}
function doTableMenu(e)
{
//do whatever it does
//stop the event propagating to the body element
var evt = e ? e : window.event;
if (evt.stopPropagation) {evt.stopPropagation();}
else {evt.cancelBubble=true;}
return false;
}
This should deal with the way each browser handles events.
$( document ).ready(function() {
var childClicked = false;
// myContainer is the nearest container div to the clickable elements
$("#myContainer").children().click(function(e) {
console.log('in element');
childClicked = true;
});
$("#myContainer").click(function(e){
if(!childClicked) {
console.log('in background');
e.preventDefault();
e.stopPropagation();
}
childClicked = false;
});
});
#myContainer {
width:200px;
height:200px;
background-color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="myContainer" style="">
link
<div style="width:50px;height:50px;background-color: white;">
another link
</div>
</div>
