jQuery/javascript在dragstart上更改元素

如何将一个元素的dragstart事件分配（传输…）到另一个元素

HTML:

$(document).ready(function(){   
    $(document).mousemove(function(event) {
        $('.drag-panel').css({"top":event.pageY-70+'px',"left":event.pageX-70+'px'});
        Mouse.x = event.pageX;
        Mouse.y = event.pageY;
    });
});
function drag(event){ 
   event.preventDefault(); 
   var panel = $('.drag-panel')[0];             
   $(panel).css({"top":Mouse.y-70+'px',"left":Mouse.x-70+'px',"display":"block"});
   //and continue dragging with $(panel) ??
}

function dragover(event){
    alert('dragover'); 
}

draggable

dropable

JS:

$(document).ready(function(){   
    $(document).mousemove(function(event) {
        $('.drag-panel').css({"top":event.pageY-70+'px',"left":event.pageX-70+'px'});
        Mouse.x = event.pageX;
        Mouse.y = event.pageY;
    });
});
function drag(event){ 
   event.preventDefault(); 
   var panel = $('.drag-panel')[0];             
   $(panel).css({"top":Mouse.y-70+'px',"left":Mouse.x-70+'px',"display":"block"});
   //and continue dragging with $(panel) ??
}

function dragover(event){
    alert('dragover'); 
}

调用

drag（）

时，是否有方法更改拖动元素
