Modify original Position on jQuery ui Drag & Drop - jquery-ui

I have an application with multiple stack of card, I would like to have a drag&drop ability between these stacks.
These stacks have a different layout in term of offset relative to the parent element.
I simplified to the max in this fiddle

} else {
$(this).css('top',15).css('left',0);
}
},
});
$(".box, .card").droppable({
activate: function( event, ui ) {return false;},
drop: function( event, ui ) {
let source_offset = ui.draggable.parent().offset();
let destination_offset = $(this).offset();
$(this)
.append(ui.draggable);
ui.draggable
.css('top', parseInt(ui.draggable.css('top')) + parseInt(source_offset.top) - parseInt(destination_offset.top))
.css('left', parseInt(ui.draggable.css('left')) + parseInt(source_offset.left) - parseInt(destination_offset.left));
console.log(ui.draggable.css('top'), ui.draggable.css('left'));
$('.card, .box').droppable('enable');
$('.card:has(*), .box:has(*)').droppable('disable');
},
});
$('.card, .box').droppable('enable');
$('.card:has(*), .box:has(*)').droppable('disable');
});
</script>

<body>
<div id='box1' class='box'>
</div>
<div id='box2' class='box'>
</div>
</body>
</html>
As you can see, when you drop a card on the other stack, the revert options move the card to the original position relative to the parent. As this offset change on different stack, I would like to be able to modify this originalPosition when the droppable stack is determined. Can you help me ?

How to check if a selected string contains a substring of an highlight in epubjs

As the title above.
Assume, I have a paragraph:
It will be seen that this mere painstaking burrower and grub-worm of a poor devil of a Sub-Sub appears to have gone through the long Vaticans and street-stalls of the earth..
The bold string is a highlight. When I drag my mouse to select string
grub-worm of a poor devil of a Sub-Sub
Then I want to check if my selected text contains the highlight(or the part of the highlight) or not. How could I do that?
The code below is the example to add a highlight when I select a text.

I assume you only know the functionality of epubjs you listed above. From rendition.on(selected,...), we can get output: cfiRange. From book.getRange(cfiRange).then(function (range)..., we can get output: range.
That means whenever we select a word or sentence, we get cfiRange and range.
cfiRange is epubcfi(/6/10[id139]!/4/2[filepos12266]/6,/3:1,/3:4, which based on position of the selected word. I don't know how it calculates/works but if you do then you can check if the cfiRange contains a existing highlight word's cfiRange.
range.toString() can give you the text. if your application is only storing a word. then you can check if the new selected word == or contain your existing highlight word.

Strange default size in leaflet map

I have taken a working Leaflet map, but when I added a JQuery Mobile header and back button the formatting went crazy.
Initially loading the page all the contents is loaded in the upper-left-hand corner, but when the page is resized the smallest bit on a desktop, or rotated on a mobile, everything is fine.
This is what it looks like when opened:
and what it looks like after rotating (and what it should be):
Here is the code for the page

jQuery Mobile has its own way to create pages from div's, so you may better stick to JQM events.
Here is a great post of Omar which explain how to solve this (typical) issue when loading Google Maps. You should wait for pagecontainershow or use a placeholder to pre-load the maps in advance.
In my example below, you will find a variation of this approach for Leaflet which uses the same canvasHeight() function (see also the answers here: set content height 100% jquery mobile).
I noticed you are about to implement a footer button for the geo-location feature, so for your convenience i show you also a possible way to do that (credits: Getting current user location automatically every “x” seconds to put on Leaflet map?).
Please note: i had to reposition the default map attribution so it won't overlap with the footer button.
var map, actualPosition, actualAccuracy, autoUpdate;
function canvasHeight(canvas) {
var mapPage = $("#page-map"),
screen = $.mobile.getScreenHeight(),
header = $(".ui-header", mapPage).hasClass("ui-header-fixed") ? $(".ui-header", mapPage).outerHeight() - 1 : $(".ui-header", mapPage).outerHeight(),
footer = $(".ui-footer", mapPage).hasClass("ui-footer-fixed") ? $(".ui-footer", mapPage).outerHeight() - 1 : $(".ui-footer", mapPage).outerHeight(),
newHeight = screen - header - footer;
$(canvas).height(newHeight);
}
$(window).on("throttledresize orientationchange", function() {
canvasHeight("#map");
})
function onLocationFound(e) {
var radius = e.accuracy / 2;
actualPosition = L.marker(e.latlng).addTo(map);
actualAccuracy = L.circle(e.latlng, radius).addTo(map);
}
function onLocationError(e) {
alert(e.message);
}
function showLocation() {
if (actualPosition) {
map.removeLayer(actualPosition);
map.removeLayer(actualAccuracy);
}
map.locate({setView: true,maxZoom: 16});
}
function loadMap(canvas) {
map = L.map(canvas).setView([43.7178, -79.3762], 11);
L.tileLayer("https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png").addTo(map);
map.on('locationfound', onLocationFound);
map.on('locationerror', onLocationError);
// Your custom initialization
//getGeoJson();
//getTPSJson();
}
function toggleAutoUpdate() {
if (autoUpdate) {
$("#autoUpdate").removeClass("ui-btn-active");
clearInterval(autoUpdate);
autoUpdate = null;
if (actualPosition) {
map.removeLayer(actualPosition);
map.removeLayer(actualAccuracy);
}
} else {
$("#autoUpdate").addClass("ui-btn-active");
showLocation();
autoUpdate = setInterval(function() {
showLocation();
// Your custom Update
//getGeoJson();
}, 10 * 1000);
}
}
$(document).on("pagecontainershow", function(e, ui) {
if (ui.toPage.prop("id") == "page-map") {
canvasHeight("#map");
if (!map) {

jQuery Mobile manages the pages of your multi-pages document and resizes them appropriately when DOM is loaded.
The issue is that you have already instantiated your map with Leaflet before that event happens, so the map container (i.e. <div id="map"></div>) is not displayed yet by jQuery Mobile, and therefore its size is not computed yet by the browser.
This is a variant of map container size not being valid yet at map instantiation. See Data-toggle tab does not download Leaflet map
Since you already have a listener on window.onload, which executes after jQuery Mobile does its stuff, you could very simply call map.invalidateSize() at that moment:
window.onload = function() {
// Request Leaflet to re-evaluate the map container size
// AFTER jQuery Mobile displays the page.
map.invalidateSize();
getGeoJson();
getTPSJson();
};

jquery droppable underline and highlighting

For past many days i have been struggling to make a draggable and droppable event with specific CSS effect. All i want is , when draggble enters or touches the droppable , an under line should appear. i am fine with underline text-decoration thing if it gives me freedom to change color and space between text/element. And when draggable over/fit , the droppable should highlight. I have tried many things out there but no luck so far. I am using below code where any element can be draggble and droppable.
Please help.

jquery returning to previous state

when i click the add image button a new image appears
when i click the new image can i revert it back to my previous state using jquery...showing the previous image with add image on hover
http://jsfiddle.net/6MmMe/37/
providing my js code below
$("div").hover(
function () {
$("<div>add image</div>").click(function() {
$(this).parent().unbind("hover").children("img").attr("src", "http://www.onlinegrocerystore.co.uk/images/goodfood.jpg");
$(this).remove();
}).appendTo(this);
},
function () {
$(this).find("div:last").remove();
}
);

The problem is that you are handling the first div, then removing it. There are a few ways to accomplish what I think are your goals.
I would recommend doing it with hide/show for easier management.
If you want to do this in jQuery, you can do it like this:
<!DOCTYPE html>
<html>
<head><script type='text/javascript' src='http://code.jquery.com/jquery-1.8.2.js'></script>
<style type='text/css'>
div div { color:red; display:none}
</style>
<script>
$(function(){
$('body > div').hover(function(){
// show "add image"
$('div', this).show();
}, function(){
// hide "add image" and reet image src.
$('div', this).hide();
$('img', this).attr("src", "http://imgs.zinio.com/magimages/500299032/2012/416238969_170.jpg");
})
// top-level click handler
.click(function(){
$('img', this).attr("src", "http://www.onlinegrocerystore.co.uk/images/goodfood.jpg");
});
});
</script>
</head>
<body>
<div>
<img src="http://imgs.zinio.com/magimages/500299032/2012/416238969_170.jpg" alt="Nov-12" title="Food Network Magazine" class="cover">
<div href="#">add image</div>
</div>
</body>
</html>
If you want to do this mostly in CSS, just toggling a class with jQuery, you can do this:
<!DOCTYPE html>
<html>
<head><script type='text/javascript' src='http://code.jquery.com/jquery-1.8.2.js'></script>
<style type='text/css'>
body > div {
background-image: url(http://imgs.zinio.com/magimages/500299032/2012/416238969_170.jpg);
width: 170px;
height:222px;
position:relative;
}
body > div.newImage:hover {
background-image: url(http://www.onlinegrocerystore.co.uk/images/goodfood.jpg);
width: 249px;
height:274px;
}
div div {
color:red;
position:absolute;
bottom:0;
margin-bottom:-16px;
display:none;
}
div:hover div {
display:block;
}
</style>
<script>
$(function(){
$('body > div').click(function(){
$(this).addClass('newImage');
}).hover(false, function(){

If you really prefer to add/remove things, you can do it like this:
<!DOCTYPE html>
<html>
<head><script type='text/javascript' src='http://code.jquery.com/jquery-1.8.2.js'></script>
<style type='text/css'>
div div { color:red;}​
</style>
<script>
$(function(){
$('body > div').hover(function(){
// show "add image"
$(this).append('<div>add image</div>');
}, function(){
// hide "add image" and reset image src.
$('div', this).remove();
$('img', this).attr("src", "http://imgs.zinio.com/magimages/500299032/2012/416238969_170.jpg");
})
// top-level click handler
.click(function(){
$('img', this).attr("src", "http://www.onlinegrocerystore.co.uk/images/goodfood.jpg");
});
});
</script>
</head>

Using jQuery slider to change Google chart viewWindow

I have prepared a simple test case with screenshot, demonstrating my problem and am probably missing a tiny bit, just few lines of code.
I have a diagram representing wins and losses in a web game over the weeks.
I.e. the vertical axis represents the game score and the horizontal axis represents numbers of weeks.
My ajax script returns the data for 52 weeks, but I'd like to add a slider and allow users change the viewed number of weeks to any number between 12 and 52.
Can anybody please advise me, how to modify the change function?
$("#money_slider").slider({
min: 12,
max: 52,
change: function(event, ui) {
// XXX what to do here with
// hAxis.viewWindow.min and .max?
}
});
Below is my complete test case, just save it to an .html file and you will be able to try it in a browser:
<!DOCTYPE HTML>
<html>
<style type="text/css">
h3,p,div {
text-align: center;

margin-right: auto;
}

I've read the Google example (on the bottom), but don't grok it yet.

My own solution (has rendering problems with Opera 11.62 though - I've filed a bug #882 for that):
