我的 Jquery ajax 页面加载并显示在 DIV 中，该 DIV 将自身置于其他页面元素之上，但 DIV 是透明的，或者它实际上位于其他组件的后面，看起来它是透明的并且需要在顶部呈现。如何在具有白色背景的其他页面上实现正常 DIV？为什么使元素不透明很难？这怎么可能是页面元素的默认行为？
Javascript
function popup() {
alert('opening popup');
var popup = $('.newpopup');
$.ajax({url:'/PandoraArendeWeb/popup.jsp',
error: function() {
alert('Error');
},
success: function(data) {
popup.html(data);
popup.show('fast');
}
}
);
/*
popup.html("test");
popup.show('fast');
*/
var screen_width = $(document).width();
var screen_height = $(document).height();
var box_width = popup.width();
var box_height = popup.height();
var top = (screen_height - box_height) / 2; // you might like to subtract a little to position it slightly higher than half way
var left = (screen_width - box_width) / 2;
popup.css({ 'position': 'absolute', 'top':top, 'left':left });
}
$(document).ready(function(){
$('button').click(function(){
popup();
});
})
我尝试创建一个 jsfiddle 来重现该问题，但似乎 jsfiddle 不能这样做，.get或者.ajax因为它无法将页面从 Internet 加载到 DIV。
你能提出什么建议？应该有一个明确的解决方案，透明度真的不应该是元素的默认状态，那么元素如何以透明度呈现？
HTML 是微不足道的
<div class="newpopup">
</div>
<button id="mypopup">popup</button>
我的 CSS 就像它永远无法达到一样是这个
.newpopup {
z-index:100;
position: absolute;
top:50%;
left:50%;
background-color:#ffffff; //not working
}
而作为实际弹出/ div 的 HTML 是这样的
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head><link href="css_js/styles.css" rel="stylesheet" type="text/css">
