I'm writing a simple jQuery plugin that will dynamically place a div under a text box whenever it has focus. I've been able to get the position just about right in all the browsers.
I have to attach two event handlers as well on the focus and blur events of the textbox. And it works okay, but the problem is that the div that has been placed under the textbox closes even when we click on it. Now it makes sense why it would so happen, it's because the textbox loses focus, but is there a way I can stop it from happening?
I tried attaching this to the blur event handler -
if($(mainElem).is(":focus")) return;
where mainElem is the div that is shown below the textbox.
Here is a jsFiddle to illustrate the problem.
You are not going to be able to use the blur event if you want to place "clickable" elements in the div that shows. One way to solve this is to bind your event listener to a more global element like the document and then filter out the targets.
Here is a code sample:
$(document).on('click', function (e) {
var targetEl = e.target,
parent = $(e.target).parents()[0];
if (relElem[0] === targetEl || self[0] === targetEl || self[0] === parent) {
$(mainElem).show();
} else {
$(mainElem).hide();
}
});
Here is an update to your fiddle: http://jsfiddle.net/9YHKW/6/
This is a fiddle that I threw together for a project a while back: http://jsfiddle.net/MYcZx/4/
While it is not based off of your fiddle (and I do apologize) I believe that the functionality is much the same as what you're looking for. My example does not include input fields, but rather spans that hold the values. And while I'm not managing focus/blur, you could add a tabIndex attribute to the spans and then add a trigger on focus that would open the menu.
var $sub = $('.subscription');
$sub
.on('click', '.remove', function() {
$(this).parent().remove();
})
.on('click', 'li', function(e) {
var $this = $(this),
$parent = $this.parent(),
$options = $parent.children('li'),
$value = $parent.siblings('.value'),
isMulti = $parent.hasClass('multi'),
values = [];
if(!isMulti) {
$options.removeClass('active');
}
$this.toggleClass('active');
$options.filter('.active').each(function() {
values.push($(this).text());
});
$value.text(values.join(', ') || 'select');
$value[(values.length ? 'add' : 'remove') + 'Class']('set');
});
var $clone = $sub.clone(true);
$('.new')
.on('click', function() {
$(this).before($clone.clone(true));
});

$("input").on("keypress",function(e){
if(e.which===13){
$("ul").last().append("<li>"+$(this).val()+"</li>");
}
$("li").on("click",function(){
$(this).toggleClass("striked");
});
$("li").on("mouseenter",function(){
$(this).css("color","green");
});
});
$("li").on("click",function(){
$(this).toggleClass("striked");
});
$("li").on("mouseenter",function(){
$(this).css("color","green");
});
$("#slide").on("click",function(){
$("input").slideToggle();
});
Here, I have used the onClick event on<li> to apply the striked class two times just to make it work for both dynamic and non-dynamic elements on the page. But the code is replicated and seems long. Is there any way to shorten so that I can write it once and it gets activated for both types of elements?
Use event delegation instead, on the ul, so you only have to set up listeners once, rather than setting up multiple listeners for every element on load and on each .append. Also, save the ul and the input jQuery-wrapped elements in a variable once rather than selecting them and wrapping them with jQuery each time they're used:
const $ul = $("ul");
const $input = $("input");
$input.on("keypress", function(e) {
if (e.which === 13) {
$ul.last().append("<li>" + $(this).val() + "</li>");
}
});
$ul.on("click", 'li', function() {
$(this).toggleClass("striked");
});
$ul.on("mouseenter", 'li', function() {
$(this).css("color", "green");
});
$("#slide").on("click", function() {
$input.slideToggle();
});
A rather generic approach would be to capture the click event and check if it is from ul
document.body.onclick = function(e){
e = e || event;
var from = findParent('ul',e.target || e.srcElement);
if (from){
/* it's a link, actions here */
}
}
//find first parent with tagName [tagname]
function findParent(tagname,el){
while (el){
if ((el.nodeName || el.tagName).toLowerCase()===tagname.toLowerCase()){
return el;
}
el = el.parentNode;
}
return null;
}
now you can change the tagName passed to the findParent function and do accordingly

You can try using the jquery all selector $('*'). For more information on this see
https://api.jquery.com/all-selector/.
Or you can add a specific class to every element you want to have an onClick action.
In my form, there's a button to add additional elements as needed by the user. For each input field, there's a .change() handler. The issue is that the .change does not fire on appended form elements but still triggers on existing form elements. Any help is appreciated.
$('.element').each(function() {
$mainElement = $(this); // memorize $(this)
$sibling = $mainElement.next('input'); // find a sibling to $this.
$sibling.change(function($mainElement) {
return function() {
$mainElement.text('My textfield changed');
}
}($mainElement));
Jsfiddle demo: http://jsfiddle.net/WCDBr/22
Try the on method:
$(document).on('change', 'input', function() {});
//or
$(document).on('change', '.inputclass', function() {});
It registers the event with the document and it should work even for newly added documents. Your change event registered with existing elements.
Just for the sake of simplicity i copy pasted the code.
On Clicking the "Add" button you not binding the change event again for the newly created element. Do This on Click:
$('#test').click(function(){
$('ul').append('<li><p class="element">Lorem ipsum</p><input/></li>');
$('.element').each(function() {
$mainElement = $(this); // memorize $(this)
$sibling = $mainElement.next('input'); // find a sibling to $this.
$sibling.change(function($mainElement) {
return function() {
$mainElement.text('My textfield changed');
}
}($mainElement));
});
});
I'm creating a panel that slides down when the user focuses the search box.
I'm terrible at Jquery but still learning, I've managed to create the basic functionality:
$(document).ready(function() {
$(".search-panel").hide();
$("#search_form [type='text']")
.focus(function() {
$(".search-panel").slideDown("fast");
})
.focusout(function() {
$(".search-panel").slideUp("fast");
});
});
with this basic functionality clicking outside the text box will fold up the panel I'm trying to implement a complex set of conditions whereby:
IF (textbox.focus) { show search panel}
IF (texbox.losefocus) && ( NOT search-panel.mouseover)
&& ( NOT (anything-in-search-panel-is-focused) )
basically I need to make sure that the user is not hovering over or interacting with the panel in some way and that the textbox is not focused before I slide it up.
JsFiddle of current situation:
http://jsfiddle.net/b9g9d6gf/
Instead of using the .focusout() function, you should bind a click function on the document.
$(document).ready(function () {
$(".search-panel").hide();
$("#search_form [type='text']")
.focus(function () {
$(".search-panel").slideDown("fast");
});
$(document).click(function(e) {
if( !( $(e.target).is('#search_form *')) ){
$(".search-panel").slideUp("fast");
}
});
});
If the document is clicked, anywhere, it looks if the target isn't a element inside #search_form. If not, it will slide up the .search-panel.
Note:
I removed the label and changed the span to labels. Clicking a label will also (un)check the checkbox inside it. Having three checkboxes making it act wrong. So either make three separate labels (instead of span) or remove it.
Updated Fiddle
Try this Working Demo
<script>
$(document).mouseup(function (e)
{
var container = $("#search_form");
if (!container.is(e.target) // if the target of the click isn't the container...
&& container.has(e.target).length === 0) // ... nor a descendant of the container
{
$(".search-panel").slideUp("fast");
}
else
{
$(".search-panel").slideDown("fast");
$("#search_form [type='text']").focus();
}
});
</script>
I am here again
SEE DEMO HERE
$(document).ready(function () {
$("#id_priori").on('click', 'li', function(){
var self = $(this),
checkbox = self.find(":checkbox")[0];
checkbox.checked = !checkbox.checked;
self.toggleClass( 'on', checkbox.checked );
}).find(":checkbox").each(function(){
$(this).closest('li').toggleClass('on', this.checked);
});
$("#id_tipo").on('click', 'li', 'label', function () {
var self = $(this),
radio = self.find(":radio")[0];
radio.checked = !radio.checked
$(":radio:not(checked)").each(function () {
$(this).closest('li').toggleClass("on", this.checked);
});
})
.find(":radio").each(function () {
$(this).closest('li').toggleClass('on', this.checked);
});
});
Everything works fine but for the labels , when I click them they dont check , doing a little tweaks it seems like one event is triggrering multiple times and it unchecks them , try setting an alert and you'll see what I mean
Any idea whats wrong ?
Because you're taking over the role of the actual input you need to allow the input element to carry on with its own behavior (http://jsfiddle.net/icodeforlove/rF2FT/2/)
if (event.target === checkbox) return;
All you need to do is return early if the target is the actual input element. Right now the input element is checking itself and then you're telling it to uncheck itself.
I know .live was depreciated and recently I was updating a page and realized I was using .live I would like to switch to .on but do not understand what to change. Here is my current code:
//Script for Choosing which form to display
$("#email-button, #text-button").live('click',
function(){
//figure out what button was clicked.
if(this.id === "email-button"){
var btnA = $(this);
var btnB = $("#text-button");
var divA = $('#email-form');
var divB = $('#text-form');
}
else{
btnA = $(this);
btnB = $("#email-button");
divA = $('#text-form');
divB = $('#email-form');
}
//make sure it is not already active, no use to show/hide when it is already set
if(btnA.hasClass('dark_button_span')){
return;
}
//see if div is visible, if so hide, than show first div
if(divB.is(":visible")){
divB.fadeOut("slow", function(){
divA.fadeIn("slow");
});
}
else{//if already hidden, just show the first div
divA.fadeIn("slow");
}
//Add and remove classes to the buttons to switch state
btnA.addClass('dark_button_span').removeClass('light_button_span');
btnB.removeClass('dark_button_span').addClass('light_button_span');
}
);
I had assistance writing the above script and do not know what to change. Simply changing .live to .on doesn't work.
Any help would be greatly appreciated!
Thanks!
The syntax for on is
$("containerElement").on("click", "targetElement(s)", function(){ });
So in your case it could be
$("body").on("click", "#email-button, #text-button", function(){ });
But being more specific than body is a good idea.
$(document).on('click', '#email-button, #text-button', function() {
// Your code
});
Should do the trick. See http://api.jquery.com/live/ and http://api.jquery.com/on/.
However, since you're using IDs, you probably don't even need .live() or delegating .on(). So the way I'd write that would be simply:
function doButtons(btnA, btnB, divA, divB) {
btnA = $(btnA); btnB = $(btnB); divA = $(divA); divB = $(divB);
// Make sure it is not already active, no use to show/hide when it is already set
if (btnA.hasClass('dark_button_span'))
return;
// See if div is visible, if so hide, then show first div.
if (divB.is(":visible")) {
divB.fadeOut("slow", function (){
divA.fadeIn("slow");
});
}
else // If already hidden, just show the first div.
divA.fadeIn("slow");
// Add and remove classes to the buttons to switch state.
btnA.addClass('dark_button_span').removeClass('light_button_span');
btnB.removeClass('dark_button_span').addClass('light_button_span');
}
$('#email-button').click(function () {
doButtons(this, '#text-button', '#email-form', '#text-form');
});
$('#text-button').click(function () {
doButtons(this, '#email-button', '#text-form', '#email-form');
});
jQuery's .on doesn't use event delegation unless you provide it a selector. In the above code, .live listens for events at the document, but that's far too much bubbling. If we were to implement it with .on though we would do the following:
var handler = function( e ) {
console.log( "Clicked" );
};
$( document ).on( "click", "#email-button, #text-button", handler );
Again though, it isn't really all that wise to listen for events on the document; ideally you would pick an element just above your selector. So if #email-button and #text-button have a common parent, you should use that in place of document.
