How to get values from multiple jQuery drag and drop
I'm struggling quite a while now with this problem and I hope someone can tell me if it's possible to do what I have in mind. And maybe most important.. how, because I have no clue.
So what I want to ac开发者_开发技巧hieve is what you see here: http://d.pr/h4N5. (sorry I can't post images yet, because I'm new here) One of the colored boxes should be dragged into one of the grey ones. That's how far I got for now, coding it.
But I need to know the values of the grey box where it's dropped on and which of the colored boxes is dropped on it. After that I'll put the values in a database.
For example: If I drop the pink box on the grey box with the number 5. I need the values: 5 and p.
Hope you understand my problem.
I was wondering as wel if it's possible to drop two of the colored boxes on one and the same grey box.
A lot of questions but I really hope someone can help me! Thanks in advance!
Check out the jQuery UI API documentation:
http://jqueryui.com/demos/draggable/
http://jqueryui.com/demos/droppable/
Then you can use something like the following if you give the grey boxes class grey
and the color boxes class color
, passing their contents as data to a PHP handler using an AJAX request:
$('.color').draggable({
revert: true
});
$('.grey').droppable({
drop: function(event, ui) {
var $drag = $(ui.draggable),
$drop = $(this),
data = {};
data.drag = $drag.text();
data.drop = $drop.text();
$.ajax({
url: "droppedToDatabase.php",
type: "POST",
data: data,
success: function(response){
// do whatever
}
}
},
tolerance: 'touch'
});
Here's an example of the UI: http://jsfiddle.net/G2rZV/
Do this on your droppables' drop event:
$('.drop').droppable({
drop: function(event, ui){
var dropValue = $(this).text();
var dragValue = ui.draggable.text();
}
});
Inside the drop
event, $(this)
refers to the jQuery object on which something was dropped, and ui.draggable
always gives you the jQuery object that has been dropped.
