I am working on this project: http://www.arbamedia.com/test/
if you go to Dyer dhe dritare on the left menu and drag one of the elements (the door or the window) into the right side (the desk) in Chrome and FF the 3 options that I have added for that elements show, so this: $("p", this).show(); works, but in IE9 when I drag an element it doesn't show the the options for dragging, rotating or deleting! I dont know what is wrong.
This is where it happens:
$(".drag").draggable({
revert : 'invalid',
helper : 'clone',
containment : 'desk',
cursorAt : { left:-11,top:-1 },
//When first dragged
stop : function(ev, ui) {
/*========================================================================*/
var pos = $(ui.helper).offset();
var left_ = ev.originalEvent.pageX - $("#desk").position().left;
var top_ = ev.originalEvent.pageY - $("#desk").position().top;
// get widht and height of the container div#desk element
var w_ = $("#desk").width();
var h_ = $("#desk").height();
objName = "#clonediv"+counter++;
objNamex = "clonediv"+counter;
$(objName).css({"left":left_,"top":top_});
var gag = 0;
$(objName).click(function () {
$("p", this).show();
$(this).addClass("selektume");
$('.rotate_handle').unbind('click');
$('.rotate_handle').click(function(){
gag += 45;
$('.selektume').rotate(gag+'deg');
});
$('.delete_handle').click(function() {
$('.selektume').remove();
});
return false;
});
$(document).click(function () {
$("p").hide();
$(".lgutipT").removeClass("selektume");
});
//check if dropped inside the conteiner div#des
if((left_ >= 0) && (left_ <= w_) && (top_ >= 0) && (top_ <= h_))
{
$(objName).css({"left":left_,"top":top_});
// assign a z-index value
zindex = left_ + top_;
$(objName).css({"z-index":zindex});
$(objName).addClass("lgutipT");
//$(objName).addClass("ui-widget-content");
$(objName).removeClass("drag");
$(objName).append('<p><img class="handler" src="images/move_button.png"><img class="rotate_handle" src="images/rotate_button.png"><img class="delete_handle" src="images/delete_button.png"></p>');
$("p", this).show();
}
/*========================================================================*/
//When an existiung object is dragged
$(objName).draggable({
containment : "#desk",
handle : ".handler",
cursor : "move"
});
}
});
Very tricky problem since there's no good documentation on how jQuery UI treats events at a core level. The solution was to unbind and rebind the click event. In IE, the click event is treated differently than other browsers. The solution was simply to rebind the click event after everything is done (1/1000 of a second delay).
My solution was to move the click event, add an unbinding on drag start, and to add a setTimeout() on rebinding the $(document).click() event listener when drag was complete.

I've been trying to implement a feature that removes the transparency of the dropdown menu on my website so that it is actually readable for visitors.
The code I am currently using, which removes transparency on scroll but not on drop down is:
$(document).ready(function(){
var stoptransparency = 100; // when to stop the transparent menu
var lastScrollTop = 0, delta = 5;
$(this).scrollTop(0);
$(window).on('scroll load resize', function() {
var position = $(this).scrollTop();
if(position > stoptransparency) {
$('#transmenu').removeClass('transparency');
} else {
$('#transmenu').addClass('transparency');
}
lastScrollTop = position;
});
$('#transmenu .dropdown').on('show.bs.dropdown', function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideDown(300);
});
$('#transmenu .dropdown').on('hide.bs.dropdown', function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideUp(300);
});
});
I tried changing it to this (and variations of this) but can't seem to get it to work:
$(document).ready(function(){
var stoptransparency = 100; // when to stop the transparent menu
var lastScrollTop = 0, delta = 5;
$(this).scrollTop(0);
$(window).on('scroll load resize', function() {
var position = $(this).scrollTop();
if(position > stoptransparency) {
$('#transmenu').removeClass('transparency');
} else {
$('#transmenu').addClass('transparency');
}
lastScrollTop = position;
});
$('#transmenu .dropdown').on('show.bs.dropdown', function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideDown(300);
$('#transmenu').removeClass('transparency');
});
$('#transmenu .dropdown').on('hide.bs.dropdown', function() {
$(this).find('.dropdown-menu').first().stop(true, true).slideUp(300);
$('#transmenu').addClass('transparency');
});
});
Any help would be greatly appreciated!
Thanks!
Without the html that this is hooking into it's a bit difficult to answer your question.
But given the fact that scrolling gets the job done, the only element I can see that could be preventing the functionality you want is that your selector to add show event handler is either selecting nothing in particular or an element in the DOM that is not the bootstrap dropdown element that triggers 'show.bs.dropdown', which is my reasoning for the first statement.
You can try the following debug code to verify:
// Should log to console with 'selected' if selector works alternatively 'not selected'
console.log($('#transmenu .dropdown').length > 0 ? 'selected' : 'not selected');
// Log to console when show event triggered
$('#transmenu .dropdown').on('show.bs.dropdown', function() {
console.log('triggered');
});
Hope that helps you find a solution. Happy coding!
see the documentation at http://api.jquery.com/on/ and it should become obvious why your fancy named events are never being triggered (without defining any event namespace in the first place).
$('#transmenu .dropdown')
.on('show', function() {})
.on('hide', function() {});
the DOM selector also might be #transmenu.dropdown instead of #transmenu .dropdown (depending if id and class attributes are present on the DOM node to select - or if one selects the parent node by id and there is/are nested node/s with a class attribute present).
I'm using jquery UI draggable. I do some works in drag function. for example I scale the dragging element according to it's position. I want to drag elements automatically to certain (x, y) (something like jquery animate({left:x, top:y}, 1000)); but I want to trigger drag function and scale element when is animating. how can I do this?
I suggest another approach to do that.
Use an external function to do the scale effect, and call it from both events (drag and animate):
var $myDraggable = $('#draggable').draggable({
drag: function( event, ui ) {
scale(ui.offset.left, ui.offset.top);
}
});
$('button').on('click', function(){
$myDraggable.animate(
{ left:100, top:100 },
{
duration: 1000,
progress: function(draggable){
scale(draggable.elem.offsetLeft, draggable.elem.offsetTop);
}
});
});
function scale(left, top){
//your scaling logic here
console.log("scaling", left, top);
}
See this example: FIDDLE

PS:This code offer a button toggle function
$(function(){
$button = $('button')
$box = $('.box')
$click = 0
$button.click(function(){
if($click !=0){
$click ++
$box.removeClass('active')
}else{
$click --
$box.addClass('active')
}
});
});
I'm using this piece of code to populate a div with the contents of a hovered element.
$('.gallery .thumbs a').hover(
function(){
var target = $(this);
$('.hover-box').html(target.clone());
var top = target.offset().top;
var left = target.offset().left;
$('.hover-box').css({'display':'block', 'top':top, 'left':left});
},
function(){
$('.hover-box').hide();
}
);
The problem is - what many seem to have had - that after adding the 'mouseleave' handler both the events start firing uncontrollably.
I know the bubbling issues related with mouseover/out but this seems to behave the same.
Anyone have an idea why this is happening?
EDIT:
Here's the deal on fiddle. Not the prettiest sight but function the same as my problem.
FIDDLE
It's because your function fires and re-fires each hover and at the end of each hover, so any time you move the mouse it fires twice. What you want to do instead is fire it on mouseenter of .thumbs a and mouseleave of .hover-box, like this
jQuery(function () {
jQuery('.thumbs a').hover(
function () {
var target = $(this);
jQuery('.hover-box').html(target.clone());
var top = target.offset().top;
var left = target.offset().left;
jQuery('.hover-box').css({
'display': 'block',
'top': top,
'left': left
});
});
$('.hover-box').mouseleave(function() {
$('.hover-box').hide();
});
});
I'm having some trouble with my Javascript when using jQuery UI's sortable method on dynamically created elements. When I hover an image it displays a larger version of the image which follows the cursor within the thumbnail. Then, when I'm sorting/dragging an image it displays the larger image with it's position set to far away from the thumbnail. The larger image should be hidden when sorting :-)
I've made a screenr so it's easier for you to see what I mean: http://screenr.com/jjv8
My code for hooking up the events:
// Selected photos hover
$('ul li img').live('mouseenter', function () {
var img = $(this);
var imgDiv = $(this).parent().find('.hover-image');
img.mousemove(function (e) {
imgDiv.show();
var x = e.pageX;
var y = e.pageY - 50;
imgDiv.css({ "top": y + "px", "left": x + "px" });
});
});
$('ul li img').live('mouseleave', function () {
$(this).parent().find('.hover-image').fadeOut('fast');
});
And my code for sorting:
selectedPhotosList.sortable({
handle: '.selected-thumbnail-image',
start: function (event, ui) {
ui.item.find('.selected-thumbnail-image').die('mouseenter');
ui.item.find('.hover-image').hide();
}
});
Yes, I'm using .live() since this is a datatype which resides in Umbraco CMS which uses an older version of jQuery, so .on() doesn't work :-)
Anyone got a hint on how to get this to work?
EDIT
I found the bug:
In my .live('mouseenter', function()... I'm calling imgDiv.show(); every time the cursor moves.
Doing it like this works:
// Selected photos hover
$('ul li img').live('mouseenter', function () {
var img = $(this);
var imgDiv = $(this).parent().find('.hover-image');
imgDiv.show();
img.mousemove(function (e) {
var x = e.pageX;
var y = e.pageY - 50;
imgDiv.css({ "top": y + "px", "left": x + "px" });
});
});
$('ul li img').live('mouseleave', function () {
$(this).parent().find('.hover-image').fadeOut('fast');
});
However, this creates another bug when using IE.: Screenr: http://screenr.com/1Iv8
The hover image is shown once before actually triggering the mousemove function :-/ Any way to overrule this?
I'd suggest:
$('ul li img').off('mouseenter');
.die() should work for you. Read the documentation on it
$('ul li img').die('mouseenter');
Something like that should work.
Found a solution to this which works in IE7+, Chrome and Firefox, although it's a bit ugly (not sure if that is an understatement ;-)):
In the sortable start event I create a copy of the hover-image and store it in a variable then removing it from the DOM. Then in the stop event I prepend it to the listitem that has been dragged/sorted. Code:
var tempHoverImage = "";
selectedPhotosList.sortable({
handle: '.selected-thumbnail-image',
start: function (event, ui) {
var hoverImage = ui.item.find('.hover-image');
tempHoverImage = hoverImage;
hoverImage.remove();
},
stop: function (event, ui) {
ui.item.prepend(tempHoverImage);
}
});
I have make this: This In the right you see a red button. When you click on the red button. The content screen with the text is coming. But i have a question of this. Can i make this with a other animation. If you hold your mouse. Then you can slide open. With your mouse button to left. Then the content box open. Do you understand it? I hope you can help me.
You can see the code on jsfiddle. And you can change it there. I hope you can help me. I am a starting javascripter. And how And have no idea how I can make this.
To implement dragging, you can make use of mousedown/mouseup/mousemove like this: http://jsfiddle.net/pimvdb/25y4K/8/.
$(function () {
"use strict";
var box = $(".what-is-delicious"),
button = $(".what-is-delicious > a");
var mouseDown = false,
grabbed = 0,
start = -303;
button.mousedown(function(e) {
mouseDown = true;
$('*').bind('selectstart', false); // prevent selections when dragging
grabbed = e.pageX; // save where you grabbed
$("body").append('<div class="background-overlay"></div>');
});
$('body').mouseup(function() {
mouseDown = false;
$('*').unbind('selectstart', false); // allow selections again
$(".background-overlay").remove();
start = parseInt(box.css('right'), 10); // save start for next time
// (parseInt to remove 'px')
}).mousemove(function (e) {
if(mouseDown) { // only if you are dragging
// set right to grabbed - pageX (difference) + start 'right' when started
// dragging. And if you drag too far, set it to 0.
box.css("right", Math.min(grabbed - e.pageX + start, 0));
}
});
});
Here is an updated fiddle. Basically I just did a couple of things:
Changed the handler from "click" to "mouseenter"
Added a "mouseleave" handler that does the opposite thing
Put the handlers on the "what-is-delicious" container instead of the <a>
The code:
$(function () {
"use strict"
var box = $(".what-is-delicious"),
button = $(".what-is-delicious > a");
box.mouseenter(function (e) {
e.preventDefault();
if ($(button).hasClass("open")) {
} else {
$("body").append('<div class="background-overlay"></div>');
button.addClass("open");
box.animate({ right: "0"}, 750);
}
}).mouseleave(function (e) {
e.preventDefault();
if ($(button).hasClass("open")) {
$("body").find('div.background-overlay').remove();
button.removeClass("open");
box.animate({ right: -303}, 750);
} else {
}
});
});
The "preventDefault()" calls aren't really necessary anymore but I left them there.
I would assume you are toggling the Style.Display of the DIV currently in an OnClick() event.
The same code can be called from a Hover() or MouseOver()
