我已经在这个网站的弹出窗口居中,但是,它只在x轴上。我也需要将它集中在y轴上,但我似乎无法实现。试图将JS弹出窗口放置在页面中心?
这里是JavaScript的...
function toggle(div_id) {
var el = document.getElementById(div_id);
if (el.style.display == 'none') { el.style.display = 'block';}
else {el.style.display = 'none';}
}
function blanket_size(popUpDivVar) {
if (typeof window.innerWidth != 'undefined') {
viewportheight = window.innerHeight;
} else {
viewportheight = document.documentElement.clientHeight;
}
if ((viewportheight > document.body.parentNode.scrollHeight) && (viewportheight > document.body.parentNode.clientHeight)) {
blanket_height = viewportheight;
} else {
if (document.body.parentNode.clientHeight > document.body.parentNode.scrollHeight) {
blanket_height = document.body.parentNode.clientHeight;
} else {
blanket_height = document.body.parentNode.scrollHeight;
}
}
var blanket = document.getElementById('blanket');
blanket.style.height = blanket_height + 'px';
var popUpDiv = document.getElementById(popUpDivVar);
popUpDiv_height=blanket_height/2-200;//200 is half popup's height
popUpDiv.style.top = popUpDiv_height + 'px';
}
function window_pos(popUpDivVar) {
if (typeof window.innerWidth != 'undefined') {
viewportwidth = window.innerHeight;
} else {
viewportwidth = document.documentElement.clientHeight;
}
if ((viewportwidth > document.body.parentNode.scrollWidth) && (viewportwidth > document.body.parentNode.clientWidth)) {
window_width = viewportwidth;
} else {
if (document.body.parentNode.clientWidth > document.body.parentNode.scrollWidth) {
window_width = document.body.parentNode.clientWidth;
} else {
window_width = document.body.parentNode.scrollWidth;
}
}
var popUpDiv = document.getElementById(popUpDivVar);
window_width=window_width/2-200;//200 is half popup's width
popUpDiv.style.left = window_width + 'px';
}
function popup(windowname) {
blanket_size(windowname);
window_pos(windowname);
toggle('blanket');
toggle(windowname);
}
我认为这将这项工作...
popUpDiv_height=blanket_height/2-200;//200 is half popup's height
,但事实并非如此。有想法该怎么解决这个吗?

这里是归因于这个弹出所有的CSS ...
#blanket {
background-color:#111;
opacity: 0.65;
filter: alpha(opacity=65)
*background:none;
position:absolute;
z-index: 9001;
top:0px;
left:0px;
width:100%;
}
#popUpDiv {
position:absolute;
background-image:url(../images/popup_bg.png);
background-repeat:no-repeat;
top:50%;
left: 50%;
width:400px;
height:400px;
margin-top: -120px auto 0 auto; /* auto, centers horizontally and -120px is half your height to finish the centering vertically */
border:5px solid #000;
z-index: 9002;
}
#popUpDiv .close {
background-image: url(../images/x.png);
background-repeat: no-repeat;
position:absolute;
top:10px;
right:10px
}
这并没有很好的工作。我已经设置了#blanket样式,但这不适用于#blanket。这是Popup本身。看到我上面的编辑... – webfrogs
OH!将您的页边距编辑为您的弹出窗口高度的一半,所以'margin-top:-200px',然后删除左边:50%。或者如果你保持'left:50%;''你必须做更多的事情'边距:-200px auto 0 -200px;' – jrthib
