( "#draggable" ).draggable({ axis: "y" });
( "#draggable3" ).draggable({ containment: "#containment-wrapper", scroll: false }); $( "#draggable5" ).draggable({ containment: "parent" }); });
沿着轴约束运动：
或者在另一个 DOM 元素中约束运动：
#draggable, #draggable2, #draggable3 { width: 100px; height: 100px; padding: 0.5em; float: left; margin: 0 10px 10px 0; }
( "#draggable" ).draggable({ cursor: "move", cursorAt: { top: 56, left: 56 } });
( "#draggable3" ).draggable({ cursorAt: { bottom: 0 } });
});
