javascript - jQueryUI 可拖动 : Constrain draggability to a single axis?

Question

拖动对象时，用户可以在 x 轴和 y 轴上拖动。我想将可拖动性限制为仅在 x 轴上。我应该怎样做呢？

谢谢!

查看 axis选项:

"Constrains dragging to either the horizontal (x) or vertical (y) axis. Possible values: 'x', 'y'."

示例:

// Initialize a draggable with the axis option specified.
$( ".selector" ).draggable({ axis: 'x' });

// Get the axis option, after initialization.
var axis = $('.selector').draggable('option', 'axis');
// Set the axis option, after initialization.
$('.selector').draggable('option', 'axis', 'x');
