想要禁用div后面的页面. [英] want to disable page behind div.
问题描述
页面上有网格，页面上有一些按钮.
我做了一个div，并通过设置其上，下，右宽度使其显示为弹出窗口，并在单击按钮时使其可见.
现在，当div像页面上的弹出窗口一样可见时，我希望禁用后页，这意味着用户无法对其执行任何操作.
请让我知道该怎么做

推荐答案
好的，这里是您要做的事情
创建半透明gif或透明gif
创建图像标签
OK here''s what you have to do
Create a semi transparent gif, or transparent gif
create an image tag
<img src="transp.gif" style="zindex=20; position:absolute; Top:0; Left:0; witdh:100%; height:100%" />
然后创建div并记住将索引设置为图像上方的索引
and then create your div remember the index to set it above the image
<div id="hideUnhideEct" style="zindex=21">div content</div>
它仍然需要进行一些实验和跨浏览器测试，但是我之前使用过它，您还应该考虑在div和image上使用position:absolute
请记住IE9中的位置绝对限制(出于某种原因，他们把它弄乱了)，最简单的解决方案是从文档的标题中删除doctype.
请记住，将宽度和高度设置为100％以包含在样式表中时
it still bears some experimenting and cross browser testing but I used this before, you should also consider using position:absolute on your div and image
Please keep in mind the position absolute restrictions in IE9 (for some reason they messed it up) easiest solution is to remove the doctype from the header of the document.
Remember when setting 100% width and height to include in your stylesheet
body, html, form{
width:100%;
height:100%;
padding: 0 0 0 0;
margin: 0 0 0 0;
}
基本逻辑是与 CSS 一起使用.有一个 z-index 在建立图层中起作用.在需要时显示覆盖的div，然后将其隐藏起来.
我有一段时间从网上回来了.不是我的.试试:
Basic logic is to play with CSS. There is a z-index that plays a role in putting up a layer. Show the overlaying div when needed and then hide it back.
I got this sometime back from net. Not mine. Try:
.parentDisable
{
z-index:999;
width:100%;
height:100%;
display:none;
position:absolute;
top:0;
left:0;
background-color: #000;
color: #aaa;
opacity: .4;
filter: alpha(opacity=50);
}
#popup
{
width:300;
height:300;
position:relative;
color: #000;
background-color: #fff;
top:25%;
}
#close
{
position:absolute;
top:0;
right:0;
}
function pop(div)
{
document.getElementById(div).style.display='block'
return false;
}
function hide(div)
{
document.getElementById(div).style.display='none'
return false;
}
<body>
<div id="pop1" class="parentDisable">
<center>
<div id="popup">
This is popup 1
<input title="Click" type="button" name="Click Me" value="Click Me" />
<a href="#" onclick="return hide('pop1')">
<div id="close">
<img src="close.png" width="40px" height="40px" />
</div>
</a>
</div>
</center>
</div>
<center>
