jquery - 如何使用 jQuery 拖动光标时调整图像大小(可拖动和可调整大小)

Question

我想重新创建此站点中图像的可拖动事件 https://alpine-groupemichel.com/alpine-a110 .

我设法拖动光标，但我不知道如何按照光标的 offset().left 调整图像大小。

$(document).ready(function(){
    var cursor = $('#drag-cursor');
    var img = $('.sliding-img');
    var xPos=0;
    cursor.draggable({
        axis: 'x',
        containment: $('.relative'),      
        drag: function(xPos) {
            var offset = $(this).offset();
            var xPos = offset.left;
            console.log(xPos);
        }
    });
});

我认为你可以使用可调整大小而不是可拖动。像这样的东西:

  $( function() {
    $( "#resizable" ).resizable({
      maxHeight: 250,
      maxWidth: 350,
      minHeight: 250,
      minWidth: 1,
      containment: "#container"
    });
  } );

#resizable, #container {background-image: url('http://lorempixel.com/400/400/')}
#resizable { width: 200px; height: 250px;  filter: grayscale(100%);}
#container { width: 400px; height: 250px; }

<link href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css" rel="stylesheet"/>

<div id="container">

<div id="resizable" class="ui-widget-content">

</div></div>
