• HTML元素遮挡Flash之梦


    wmode参数:
    
    transparent模式:可用z-index控制层级
    
    opaque模式:可用z-index控制层级
    
    window模式:flash层级在浏览器核心显示窗口之上,flash会盖住与他重合的html

    情景1(可修改flash的wmode参数)

    修改wmode属性为,transparent或opaque

    DEMO如下:

    <!doctype html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title> HTML元素遮挡Flash之梦 - 情景1 </title>
        <style>
            html, body, object, embed{ padding: 0; margin: 0; }
            .m-box { position: relative; }
    
            .m-flash, .m-flash embed { width: 400px; }
            .m-shadow { position: absolute; top: 0; left: 0; width: 100px; height: 100px; background-color: #ccc; }
        </style>
    </head>
    <body>
    <!--transparent-->
    <div class="m-box">
        <object class="m-flash" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">
            <param name="src" value="http://www.w3school.com.cn/i/bookmark.swf">
            <param name="wmode" value="transparent"/>
            <embed wmode="transparent" src="http://www.w3school.com.cn/i/bookmark.swf"></embed>
        </object>
    
        <div class="m-shadow">
            Jununx,欢迎您!--transparent
        </div>
    </div>
    
    <!--opaque-->
    <div class="m-box">
        <object class="m-flash" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">
            <param name="src" value="http://www.w3school.com.cn/i/bookmark.swf">
            <param name="wmode" value="opaque"/>
            <embed wmode="opaque" src="http://www.w3school.com.cn/i/bookmark.swf"></embed>
        </object>
    
        <div class="m-shadow">

    <html lang="en">
    <head>
        <meta charset="UTF-8">

            .m-flash, .m-flash embed { width: 400px; }
            .m-flash { position: relative; z-index: 1; }
            .m-shadow { position: absolute; top: 0; left: 0; z-index: 2; width: 100px; height: 100px; background-color: #ccc; }
            .m-shadow-txt { position: absolute; z-index: 2; }
            .m-shadow-ifr { position: absolute; z-index: -1; width: 100%; height: 100%; opacity: 0; filter: alpha(opacity=0); }
        </style>
    </head>
    <body>
    <!--window-->
    <div class="m-box">
