javascript - jQueryUI - Detect if element is beeing dragged

Question

I want to get the position of an element when it is beeing dragged.

My code so far:

$(document).ready(function(){


    $("p").text($("div").position().left);
    $("p").text($("div").position().top);

    $("div").draggable();

})

This only gets the position when the page loads. I want to detect whenever the div is beeing dragged so I can write its position in the p tag.

Answer 1

$('#dragThis').draggable(
    {
        drag: function(){
            var offset = $(this).offset();
            var xPos = offset.left;
            var yPos = offset.top;
            $('#posX').text('x: ' + xPos);
            $('#posY').text('y: ' + yPos);
        }
    });

Answer 2

你应该看看 jQuery 官方文档的事件部分：http: //jqueryui.com/draggable/#events

该drag事件将在被拖动时引发，您可以从那里获得偏移量。例如：

$(this).offset().left;
$(this).offset().top;
