如题，目前只能往右下角拖拉，而不能往其他方向拉，我想实现Win10桌面一模一样的拖拉，不知道算法改怎么写了。下面是已经写好的JS，有大佬看下怎么改进，才能实现和Win10桌面一样的拖拉呢[JavaScript]var Mil = false;var NewDiv = document.createElement('div');function getMousePos(event) { var e = event || window.event; var scrollX = document.documentElement.scrollLeft || document.body.scrollLeft; var scrollY = document.documentElement.scrollTop || document.body.scrollTop; var x = e.pageX || e.clientX + scrollX; var y = e.pageY || e.clientY + scrollY; return { 'x': x, 'y': y };}function Mi(e) { document.body.appendChild(NewDiv); NewDiv.id = 'Move_div'; move_div = document.getElementById("Move_div"); var m_down_x = getMousePos(e).x; var m_down_y= getMousePos(e).y; move_div.style.left = m_down_x + "px"; move_div.style.top = m_down_y + "px"; move_div.style.width = m_down_x - parseInt(move_div.style.left) +"px"; move_div.style.height = m_down_y - parseInt(move_div.style.top) +"px"; Mil = true;}function move(e){ if(Mil){ move_div = document.getElementById("Move_div"); var m_move_x = getMousePos(e).x; var m_move_y= getMousePos(e).y; move_div.style.width = m_move_x - parseInt(move_div.style.left) +"px"; move_div.style.height = m_move_y - parseInt(move_div.style.top) +"px"; }}function up(){ Mil = false; document.body.removeChild(document.getElementById("Move_div"));}[Html]<body onmousemove="move(event)" onmouseup="up()" onmousedown="Mi(event)">[Css]#Move_div{ background-color: rgba(162, 204, 242, 0.35); box-shadow: 0 0px 0.1px 0 rgba(255, 255, 255, 0.88); position: fixed;}相关地址：https://blog.lfio.net/
