我想背景模糊的div.我只能找到适用于图像的解决方案作为背景,而不是HTML元素.它是移动使用所以CSS3不是问题.我把一个JSfiddle放在一起展示了我的困境.
我想要的结果:当下拉列表出现时,它会模糊其后面所有元素的内容,而不是整个页面.
以下是HTMLJSFiddle的示例目的:
<a href="#" id="link">open/close</a>
<div id="slide">
<p>Text Text Text Text Text Text Text Text </p>
<p>Text Text Text Text Text Text Text Text </p>
<p>Text Text Text Text Text Text Text Text </p>
<p>Text Text Text Text Text Text Text Text </p>
</div>
<div id="page_content">
<p>Page content, not images Page content, not images Page content, not images </p>
<p>Page content, not images Page content, not images Page content, not images </p>
<p>Page content, not images Page content, not images Page content, not images </p>
<p>Page content, not images Page content, not images Page content, not images </p>
</div>

我试图让"接受的答案"起作用,但由于某种原因,它从JSfiddle中提取时不起作用
这是我的代码:

<script>
$( document ).ready(function() {
$('#link').click(function() {
$('#slide').slideToggle('slow', function() {
});
});
$('#main-view').click(function(){
html2canvas(document.body, {
onrendered: function (canvas) {
document.body.appendChild(canvas);
},
width: 300,
height: 100
});
$('#cover').slideToggle('fast', function(){
$('#partial-overlay').slideToggle();
});
});
});
</script>

我已经尝试过使用和不使用DOM准备好的包装器
我相信这就是您正在寻找的。我使用画布元素。我怀疑，随着即将发布的 iOS7 使用此效果，这将变得非常流行。
