閑來無事，把項目里很土的彈窗，改成了遮罩層顯示，感覺效果好點了。上代碼：
父頁面：

復制代碼 代碼如下:

<div>
<%@include file='/WEB-INF/jsp/infobackup/martyr/printCertDia.jsp' %>
<%--<jsp:include page="/WEB-INF/jsp/infobackup/martyr/printCertDia.jsp" flush=”true”/> --%>
</div>

復制代碼 代碼如下:

//mask遮罩層
var newMask = document.createElement("div");
newMask.id = m;
newMask.style.position = "absolute";
newMask.style.zIndex = "1";
_scrollWidth = Math.max(document.body.scrollWidth, document.documentElement.scrollWidth);
_scrollHeight = Math.max(document.body.scrollHeight, document.documentElement.scrollHeight);
newMask.style.width = _scrollWidth + "px";
newMask.style.height = _scrollHeight + "px";
newMask.style.top = "0px";
newMask.style.left = "0px";
newMask.style.background = "#666";
newMask.style.filter = "alpha(opacity=40)";
newMask.style.opacity = "0.40";
document.body.appendChild(newMask);

復制代碼 代碼如下:

newDiv=document.getElementById("newDiv1");
// var newDiv = document.createElement("div");
// newDiv.id = _id;
newDiv.style.position = "absolute";
newDiv.style.zIndex = "9999";
newDivWidth = 700;
newDivHeight = 600;
newDiv.style.width = newDivWidth + "px";
newDiv.style.height = newDivHeight + "px";
newDiv.style.top = (document.body.scrollTop + document.body.clientHeight / 2 - newDivHeight / 2) + "px";
newDiv.style.left = (document.body.scrollLeft + document.body.clientWidth / 2 - newDivWidth / 2) + "px";
newDiv.style.background = "#F7F7EF";
newDiv.style.border = "1px solid #860001";
newDiv.style.padding = "5px";
newDiv.style.display='';

復制代碼 代碼如下:

function newDivCenter() {
newDiv.style.top = (document.body.scrollTop + document.body.clientHeight / 2 - newDivHeight / 2) + "px";
newDiv.style.left = (document.body.scrollLeft + document.body.clientWidth / 2 - newDivWidth / 2) + "px";
}
if (document.all) {
window.attachEvent("onscroll", newDivCenter);
}
else {
window.addEventListener('scroll', newDivCenter, false);
}

復制代碼 代碼如下:

var newA = document.createElement("a");
newA.href = "#";
newA.innerHTML = "關閉";
newA.onclick = function() {
if (document.all) {
window.detachEvent("onscroll", newDivCenter);
}
else {
window.removeEventListener('scroll', newDivCenter, false);
}
document.body.removeChild(docEle("newDiv1"));
document.body.removeChild(docEle(m));
document.getElementById("certImg").style.display='';
return false;
}
newDiv.appendChild(newA);
