我需要以下功能
我需要类似于操作系统拖放功能的应用程序。
我的问题是,如果我想选择拖动鼠标指针项的多个项目,如何解决它。
我尝试使用代码,但在选择多个项目时存在一些缺陷。
$(document).ready(function(){
var selectedClass = 'ui-state-highlight',
clickDelay = 600, // click time (milliseconds)
lastClick, diffClick; // timestamps
$("#draggable li")
// Script to deferentiate a click from a mousedown for drag event
.bind('mousedown mouseup', function(e){
if (e.type=="mousedown") {
lastClick = e.timeStamp; // get mousedown time
} else {
diffClick = e.timeStamp - lastClick;
if ( diffClick < clickDelay ) {
// add selected class to group draggable objects
$(this).toggleClass(selectedClass);
}
}
})
.draggable({
revertDuration: 10, // grouped items animate separately, so leave this number low
containment: '.demo',
start: function(e, ui) {
ui.helper.addClass(selectedClass);
},
stop: function(e, ui) {
// reset group positions
$('.' + selectedClass).css({ top:0, left:0 });
},
drag: function(e, ui) {
// set selected group position to main dragged object
// this works because the position is relative to the starting position
$('.' + selectedClass).css({
top : ui.position.top,
left: ui.position.left
});
}
});
$("#droppable, #draggable")
.sortable()
.droppable({
drop: function(e, ui) {
$('.' + selectedClass)
.appendTo($(this))
.add(ui.draggable) // ui.draggable is appended by the script, so add it after
.removeClass(selectedClass)
.css({ top:0, left:0 });
}
});
});

使用可选网格示例代码并添加可拖动+可排序功能,如下例所示:http://jqueryui.com/demos/draggable/#sortable
