============================================================

snap-to (吸附移动)：

$(”#draggable”).draggable({ snap: true }); //默认，任何方式吸附

$(”#draggable2″).draggable({ snap: ‘.ui-widget-header’ }); //以某元素的内外径吸附

$(”#draggable3″).draggable({ snap: ‘.ui-widget-header’, snapMode: ‘outer’ }); //以某元素外径吸附,吸附方式:本上吸其下，本下吸其上. 内径吸附：inner, 吸附方式:相反

$(”#draggable4″).draggable({ grid: [20,20] });//以一定距离移动

$(”#draggable5″).draggable({ grid: [80, 80] });

============================================================

scroll：
$(”#draggable”).draggable({ scroll: true });

$(”#draggable2″).draggable({ scroll: true, scrollSensitivity: 100 }); //滚动条敏感度

$(”#draggable3″).draggable({ scroll: true, scrollSpeed: 100 }); //滚动速度

============================================================

revert position(恢复到原始位置)：

cursor: ‘move’, //设置鼠标图形

cursorAt: { top: -12, left: -20 }, //位置定位坐标设置

helper: function(event) {

return $(’

I\’m a custom helper

’);

} //新建提示元素,上面设置其以鼠标定位位置值

});

$(”#set div”).draggable({ stack: { group: ‘#set div’, min: -1 } });//群组设置拖动,并且最后添加的元素叠加到该群组的最上面.适合做许愿板效果。

============================================================

Drag handle (拖动点设置)：
$(”#draggable”).draggable({ handle: ‘p’ }); //handle设置实现拖动位置

$(”#draggable2″).draggable({ cancel: “p.ui-widget-header” }); //cancel设置限制拖动位置
============================================================

$(”#draggable”).draggable({ cursorAt: { cursor: ‘move’, top: 56, left: 56 } }); //cursor设置鼠标样式, top、left、right、bottom设置元素相对鼠标的定位点
