仿QQ空间图片弹出效果
参考网上代码，自己做了一个仿QQ空间图片弹出效果，但现在还无法在弹出层切换图片。
以下是js代码：
function imageShow(which_click) {var image_path = which_click.src;//alert(image_path);var tag_top = Math.max(document.documentElement.scrollTop, document.body.scrollTop);//创建底层灰色DIVvar index_tag = document.createElement("div");index_tag.style.cssText = "width:100%;height:"+Math.max(document.body.clientHeight,document.body.offsetHeight,document.documentElement.clientHeight)+"px;position:absolute;background:black;top:0;filter: Alpha(Opacity=80);Opacity:0.8;";document.body.appendChild(index_tag);index_tag.ondblclick = closeIndexTag;//创建图片DIVvar img_tag = document.createElement("div");img_tag.style.cssText = "font:12px /18px verdana;overflow:auto;text-align:center;position:absolute;width:200px;border:5px solid white;background:white;color:white;left:"+(parseInt(document.body.offsetWidth)/2-100)+"px;top:"+(document.documentElement.clientHeight/3+tag_top)+"px;";img_tag.innerHTML = "<div style='padding:10px;background:#cccccc;border:1px solid white'><img src='images/loading.gif' /><br /><br /><b style='color:#999999;font-weight:normal'>Image loading...</b><br /></div>";img_tag.oncontextmenu = function() {var clsOK=confirm("是否确定关闭图片显示"); if(clsOK)closeIndexTag();return false;}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 = "<b style='background:red;border:1px solid white;filter:Alpha(Opacity=50);Opacity:0.5;cursor:pointer;'> 关闭 </b>";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) < xx) {img_tag.style.width = (img_tag_x + temp) + "px";img_tag.style.left = (scroll_x - img_tag_x - temp)/2 + "px";} else {stop_x = true;img_tag.style.width = xx + "px";img_tag.style.left = (scroll_x - xx)/2 + "px";}if((img_tag_y + temp) < yy) {img_tag.style.height = (img_tag_y + temp) + "px";img_tag.style.top = (tag_top + (scroll_y - img_tag_y - temp)/2) + "px";} else {stop_y = true;img_tag.style.height = yy + "px";img_tag.style.top = (tag_top + (scroll_y - yy)/2) + "px";}if(stop_x && stop_y) {clearInterval(maxTime);img_tag.appendChild(img);temp = 0;imgOpacity(temp);}}, 1);img_tag.innerHTML="";img_tag.appendChild(close_tag);}function closeIndexTag() {document.body.removeChild(index_tag);document.body.removeChild(img_tag);}function imgOpacity(temp_imgOpacity) {var temp = temp_imgOpacity;temp += 10;img.style.filter = "alpha(opacity=" + temp + ")";img.style.opacity = temp/100;var imgTime = setTimeout(function() {imgOpacity(temp);}, 10);if(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);}}?
