Jquery ui 如何获取可拖动元素的类名？

在Dropable函数中，如何获取当前正在拖动的可拖动元素的类名

$( ".drop" ).droppable( { accept: handleFunction } );
function handleFunction(draggable){
//How to get currently dragging element's class name
}

我认为您没有正确使用

accept

选项。它不获取当前正在拖动的可拖动文件，而是测试您刚才在

droppable

元素中拖放的可拖动文件。发件人：

无论如何，作为参数得到的是jQuery元素，而不是JS对象。您可以通过多种方式测试其类：

$( ".drop" ).droppable( { accept: handleFunction } );
function handleFunction(draggable){
     // This will return ALL classes attached to this draggable element as a string
     // This is probably NOT what you need; it's VERY fragile
     var className = $(draggable).attr('class');

     // This returns a boolean for testing if myClass is present in the element's classes
     // This is a very common function and probably what you want
     var test = $(draggable).hasClass('myClass');

     // Note return value should be a boolean.
     return test;
}

请给我一个解决方案。你能告诉我们你试过什么吗？draggable.className和其他东西。我也不知道，所以我只是想知道类名。我搜索了大约3个小时，但是找不到。你能告诉我，我怎样才能得到这个班的名字吗？

$( ".drop" ).droppable( { accept: handleFunction } );
function handleFunction(draggable){
     // This will return ALL classes attached to this draggable element as a string
     // This is probably NOT what you need; it's VERY fragile
     var className = $(draggable).attr('class');

     // This returns a boolean for testing if myClass is present in the element's classes
     // This is a very common function and probably what you want
     var test = $(draggable).hasClass('myClass');

     // Note return value should be a boolean.
     return test;
}
