本文实例讲述了JS实现的仿QQ空间图片弹出效果代码。分享给大家供大家参考，具体如下：

"; img_tag.oncontextmenu = function() { var clsOK=confirm("是否确定关闭图片显示"); if(clsOK) closeIndexTag(); return false; } img_tag.onclick = closeIndexTag; //img_tag.onmousemove = barDidplay; document.body.appendChild(img_tag); //构建图片关闭按钮 var close_tag = document.createElement("div"); close_tag.style.cssText = "display:none;position:absolute;left:10px;top:10px;color:black;"; close_tag.innerHTML = " 关闭 "; close_tag.onclick = closeIndexTag; var img = new Image(); img.src = image_path; img.style.cssText = "border:1px solid #cccccc;filter: Alpha(Opacity=0);Opacity:0;cursor:pointer"; img.onload = imgOK(); function imgOK() { var temp = 0; var stop_x = false; var stop_y = false; var img_tag_x = img_tag.offsetWidth; var img_tag_y = img_tag.offsetHeight; var img_x = img.width; var img_y = img.height; var scroll_x=document.documentElement.clientWidth; var scroll_y=window.innerHeight||document.documentElement.clientHeight; var yy = 0; var xx = 0; if(img_y > scroll_y || img_x > scroll_x){ yy = scroll_y - 100; xx = (img_x / img_y) * yy; }else{ xx = img_x + 4; yy = img_y + 3; } img.style.width=xx-4+'px'; img.style.height=yy-3+'px'; var maxTime = setInterval(function() { temp += 30; if((img_tag_x + temp) 100) clearTimeout(imgTime); } var bar_show; function barDidplay(){ clearTimeout(bar_show); close_tag.style.display = "block"; bar_show = setTimeout(function() {close_tag.style.display = "none"}, 1000); } }
