Using jquery.collapsible.js I notice that the tabindex does not change when expanded/closed. I nearly have a solution but would appreciate it if someone could improve on this piece of code as I am sure there is a better way to do this.
$('.collapsible').each(function() {
$('.collapsible').on('click',function(e) {
if($('div').hasClass('collapsible collapse-open')) {
$('.collapsible.collapse-open').attr("tabIndex", 0);
} else {
$('.collapsible.collapse-close').attr("tabIndex", -1);
}
});
});
The problem is the tabindex only changes on the second click and then the 0,-1 order is wrong.
If you're just looking for a better way, and your solution already works, you could simplify it with this. You don't need to loop through each .collapsible with the each function just to add the click event handler.
$(".collapsible").on('click', function (e) {
var self = $(this);
var tabIndex = self.hasClass("collapse-open") ? 0 : -1;
self.attr("tabIndex", tabIndex);
});
This will select any element with the class collapsible, bind the click event, and then check if that element has the collapse-open class to determine which tab index to apply.
Thanks to Ihan for the more efficient script. It is working now I just had to change the default class from 'collapse-open' to 'collapse-close'.
$(".collapsible").on('click', function (e) {
var self = $(this);
var tabIndex = self.hasClass("collapse-close") ? 0 : -1;
self.attr("tabIndex", tabIndex);
});

jQuery(document).ready(function($) {
$(".se-q").click( function () {
var container = $(this).parents(".se-c");
var answer = container.find(".se-a");
var trigger = container.find(".se-t");
answer.slideToggle(200);
if (trigger.hasClass("se-o")) {
trigger.removeClass("se-o");
}
else {
trigger.addClass("se-o");
}
})
});
You can use .not() , removeClass() , toggleClass();
jQuery(document).ready(function($) {
$(".se-q").click( function () {
var container = $(this).parents(".se-c");
var answer = container.find(".se-a");
var trigger = container.find(".se-t");
answer.slideToggle(200);
$('.se-t').not(trigger).removeClass('se-o'); // remove the class from all .se-t element but not this one(container.find(".se-t"))
trigger.toggleClass("se-o"); // toggle class for this(container.find(".se-t"))
})
});
Note: you can catch the point from my code .. but actually you need to provide your html code .. what I got from your code its
question/answer script .. so you may need to toggle answer as
well
For answer you can use the next line before answer.slideToggle(200);
$('.se-a').not(answer).slideUp(200);
I'm writing a simple jQuery plugin that will dynamically place a div under a text box whenever it has focus. I've been able to get the position just about right in all the browsers.
I have to attach two event handlers as well on the focus and blur events of the textbox. And it works okay, but the problem is that the div that has been placed under the textbox closes even when we click on it. Now it makes sense why it would so happen, it's because the textbox loses focus, but is there a way I can stop it from happening?
I tried attaching this to the blur event handler -
if($(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));
});
I am looking for a way to manage the events. I have a hover function for element A, and click function for element B. I want to disable A`s hover function temporary while the second click of B.
I am looking for a way that not necessary to rewrite the hole function of A inside of B. Something very simply just like "Store and Disable Event, Call Stored Function"
I found some technique like .data('events') and console.log. I tired but failed, or maybe I wrote them in a wrong way.
Please help and advice!
$(A).hover();
$(b).click(
if($.hasData($(A)[0])){ // if A has event,
//STORE all the event A has, and disable
}else{
//ENABLE the stored event for A
}
);
Try this
var hoverme = function() {
alert('Hover Event Fired');
};
$('.A').hover(hoverme);
var i = 0;
$('.B').on('click', function(){
if(i%2 === 0){
// Unbind event
$('.A').off('hover');
}
else{
// Else bind the event
$('.A').hover(hoverme);
}
i++;
});
Check Fiddle
I think that what you want to do is something like this (example for JQuery 1.7.2):
$("#a").hover(function(){alert("test")});
$("#a")[0].active=true;
$("#b").click(function(){
if($("#a")[0].active){
$("#a")[0].storedEvents = [];
var hoverEvents = $("#a").data("events").mouseover;
jQuery.each(hoverEvents , function(key,handlerObj) {
$("#a")[0].storedEvents.push(handlerObj.handler);
});
$("#a").off('hover');
}else{
for(var i=0;i<$("#a")[0].storedEvents.length;i++){
$("#a").hover($("#a")[0].storedEvents[i]);
}
}
$("#a")[0].active = ($("#a")[0].active)==false;
});
JSFiddle Example
But there are a couple of things that you must have in consideration:
This will only work if you add the events with JQuery, because JQuery keeps an internal track of the event handlers that have been added.
Each version of JQuery handles data("events") differently, that means that this code may not work with other version of JQuery.
I hope that this helps.
EDIT:
data("events") was an internal undocumented data structure used in JQuery 1.6 and JQUery 1.7, but it has been removed in JQuery 1.8. So in JQuery 1.8 the only way to access the events data is through: $._data(element, "events"). But keep in mind the advice from the JQuery documentation: this is not a supported public interface; the actual data structures may change incompatibly from version to version.
You could try having a variable that is outside the scope of functions a and b, and use that variable to trigger the action to take in function b on function a.
var state;
var a = function() {
if(!state) {
state = true;
// Add hover action and other prep. I'd create a third function to handle this.
console.log(state);
};
var b = function() {
if(state) {
state = false;
// Do unbinding of hover code with third function.
} else {
state = true;
// Do whatever else you needed to do
}
}
Without knowing more about what you're trying to do, I'd try something similar to this.
It sounds like you want to disable the click hover event for A if B is clicked.
$("body").on("hover", "#a", function(){
alert("hovering");
});
$("#b").click( function(){
$("body").off("hover", "#a", function() {
alert("removed hovering");
});
});
You can use the jQuery off method, have a look at this fiddle. http://jsfiddle.net/nKLwK/1/
Define a function to assign to hover on A element, so in b click, call unbind('hover') for A element and in second click on b element define again a function to hover, like this:
function aHover(eventObject) {
// Todo when the mouse enter object. You can use $(this) here
}
function aHoverOut(eventObject) {
// Todo when the mouse leave the object. You can use $(this) here
}
$(A).hover(aHover, aHoverOut);
// ...
$(b).click(function(eventObject) {
if($.hasData($(A)[0])){ // if A has event,
$(A).unbind('mouseenter mouseleave'); // This is because not a event hover, jQuery convert the element.hover(hoverIn, hoverOut) in element.bind('mouseenter', hoverIn) and element.bind('mouseleave', hoverOut)
}else{
$(A).hover(aHover, aHoverOut);
}
});
There are provably better ways to do it, but this works fine, on document ready do this:
$("#a")[0].active=false;
$("#b").click(function(){
$("#a")[0].active = ($("#a")[0].active)==false;
if($("#a")[0].active){
$("#a").hover(function(){alert("test")});
}else{
$("#a").off('hover');
}
});
JSFiddle example
You can use .off function from jQuery to unbind the hover on your "a" element.
function hoverA() {
alert('I\'m on hover');
}
$('#a').hover( hoverA );
var active = true;
$('#b').on('click', function(){
if(active){
$('#a').off('hover');
active = false;
} else{
$('#a').hover(hoverA);
active = true;
}
});

I have a small jQuery script:
$('.field').blur(function() {
$(this).next().children().hide();
});
The children that is hidden contains some links. This makes it impossible to click the links (because they get hidden). What is an appropriate solution to this?
This is as close as I have got:
$('.field').blur(function() {
$('*').not('.adress').click(function(e) {
foo = $(this).data('events').click;
if(foo.length <= 1) {
// $(this).next('.spacer').children().removeClass("visible");
}
$(this).unbind(e);
});
});
The uncommented line is suppose to refer to the field that is blurred, but it doesn't seem to work. Any suggestions?
You can give it a slight delay, like this:
$('.field').blur(function() {
var kids = $(this).next().children();
setTimeout(function() { kids.hide(); }, 10);
});
This gives you time to click before those child links go away.
This is how I ended up doing it:
var curFocus;
$(document).delegate('*','mousedown', function(){
if ((this != curFocus) && // don't bother if this was the previous active element
($(curFocus).is('.field')) && // if it was a .field that was blurred
!($(this).is('.adress'))
) {
$('.' + $(curFocus).attr("id")).removeClass("visible"); // take action based on the blurred element
}
curFocus = this; // log the newly focussed element for the next event
});
I believe you can use .not('a') in this situation:
$('.field').not('a').blur(function() {
$(this).next().children().hide();
});
This isn't tested, so I am not sure if this will work or not.
I am using jQuery to show / hide lists, but it takes two clicks on a link instead of just one to show the list. Any help?
jQuery.showList = function(object) {
object.toggle(function(){
object.html("▾");
object.siblings("ul.utlist").show("fast");
}, function(){
object.html("▸");
object.siblings("ul.utlist").hide("fast");
});
}
$(document).ready(function() {
$("#page").click(function (e){
e.preventDefault();
var target = $(e.target);
var class = target.attr("class");
if(class == "list")
$.showList(target);
});
});
It's probably because toggle thinks the object is already visible, and executes the 'hide' clause.
edit:
Eh.. quite circular logic; how else would a user be able to click on it :-)
PS. You changed the logic from is-object-visible? to is-list-visible? in your own reply.
Not sure if this will fix everything but stop using reserved keywords.
Change variable class to something like c. And Change object variable to at least obj.
Doing the following worked well
jQuery.showList = function(obj) {
var list = obj.siblings("ul.utlist");
if(list.is(":visible")){
obj.html("▸");
list.hide("fast");
} else {
obj.html("▾");
list.show("fast");
}
}
