jQuery Mobile Droppable disabled 选项

jQuery Mobile是一种基于网络的技术，用于为网站制作响应式内容，可以在所有类型的智能手机、平板电脑和台式机上访问。在这篇文章中，我们将使用jQuery Mobile Droppable disabled 选项来禁用droppable，如果设置为真，这也接受布尔值参数。

语法： disabled选项取一个布尔值，语法如下。如果为真，我们可以禁用该面板，反之亦然。

$("#selector").droppable({
    disabled: true
});

获取disabled 选项

var disabled = $( ".selector" ).droppable( "option", "disabled" );

设置disabled 选项

$( ".selector" ).droppable( "option", "disabled", false );
