基本拖拽效果,使用 mousedown , mousemove , mouseup实现
小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
1.一個(gè)div拖拽效果
<!DOCTYPE html> <html lang="en"> <head><meta charset="UTF-8"><title>基本拖拽效果</title><script src="../../common/jquery-1.8.3.min.js"></script><style>*{margin:0;padding:0;}.drag{width:100px;height:100px;background-color:red;position:absolute;top:40px;left:50px;}</style> </head> <body><div class="drag"></div> </body> <script>$(function(){var _move = false;var _x,_y;$(".drag").mousedown(function(e){console.log(e.pageX, e.pageY);_move = true;_x = e.pageX - parseInt($(".drag").css("left"));_y = e.pageY - parseInt($(".drag").css("top"));$(".drag").fadeTo(20,0.5);})$(document).mousemove(function(e){if(_move){var x = e.pageX - _x;var y = e.pageY - _y;$(".drag").css({"left":x,"top":y});}}).mouseup(function(){_move = false;$(".drag").fadeTo("fast",1);})}) </script> </html>2.多個(gè)div單獨(dú)進(jìn)行拖拽
<!DOCTYPE html> <html lang="en"> <head><meta charset="UTF-8"><title>基本拖拽效果</title><script src="../../common/jquery-1.8.3.min.js"></script><style>*{margin:0;padding:0;}.drag{width:100px;height:100px;background-color:red;position:absolute;top:40px;left:50px;}</style> </head> <body><div class="drag"></div><div class="drag"></div> </body> <script>$(function(){$(".drag").each(function(){var _move = false;var _x,_y;var _this = $(this);$(this).mousedown(function(e){console.log(e.pageX, e.pageY);_move = true;_x = e.pageX - parseInt(_this.css("left"));_y = e.pageY - parseInt(_this.css("top"));_this.fadeTo(20,0.5);})$(document).mousemove(function(e){if(_move){var x = e.pageX - _x;var y = e.pageY - _y;_this.css({"left":x,"top":y});}}).mouseup(function(){_move = false;_this.fadeTo("fast",1);})})}) </script> </html>
