jquery – 如何在页面加载时自动弹出CSS3模态窗口？

我试图解决这个问题.如何让我在页面加载工作.

我的css

.modalDialog {
    position: fixed;
    font-family: Arial,Helvetica,sans-serif;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    background: rgba(0,0.8);
    z-index: 99999;
    opacity:0;
    -webkit-transition: opacity 400ms ease-in;
    -moz-transition: opacity 400ms ease-in;
    transition: opacity 400ms ease-in;
    pointer-events: none;
}

.modalDialog:target {
    opacity:1;
    pointer-events: auto;
}

.modalDialog > div {
    width: 400px;
    position: relative;
    margin: 10% auto;
    padding: 5px 20px 13px 20px;
    border-radius: 10px;
    background: #fff;
    background: -moz-linear-gradient(#fff,#999);
    background: -webkit-linear-gradient(#fff,#999);
    background: -o-linear-gradient(#fff,#999);
}

.close {
    background: #606061;
    color: #FFFFFF;
    line-height: 25px;
    position: absolute;
    right: -12px;
    text-align: center;
    top: -10px;
    width: 24px;
    text-decoration: none;
    font-weight: bold;
    -webkit-border-radius: 12px;
    -moz-border-radius: 12px;
    border-radius: 12px;
    -moz-Box-shadow: 1px 1px 3px #000;
    -webkit-Box-shadow: 1px 1px 3px #000;
    Box-shadow: 1px 1px 3px #000;
}

.close:hover { background: #00d9ff; }

并打开弹出窗口我们有这个链接

<a href="#openModal">Open Modal</a>

我尝试了这种技术How to make a modal window in HTML5 and CSS3 popup automatically
但它没有用..请帮忙.谢谢

ps：我也尝试使用jQuery链接点击页面加载,但这也没有用:(
这是jquery代码.

$(window).load(function () {
$("#preloader").delay(1000).fadeOut(1000);
$('#notLoggedModalClick').click();

});

解决方法

设置一个div

<div id="popup">
        text here...
</div>

在样式集显示：隐藏

#popup
{
    position:absolute;
    display:none;
    top:200px;
    left:50%;
    width:500px; 
    margin-left:-250px;
    border:1px solid blue; 
    padding:20px;
    background-color:white;
}

加载页面时只需设置display：block

<script type="text/javascript">
    function show_popup()
    {
      document.getElementById('popup').style.display = 'block'; 
    }

    window.onload = show_popup;
</script>
