HTML嵌入SWF教程

HTML嵌入SWF两种方式

• 采用SWFObject.js（依赖swfobject.js）

<script type="text/javascript"> 
    var swfVersionStr = "10.0.0"; 
    var xiSwfUrlStr = "playerProductInstall.swf"; 
    var flashvars = {}; 
    flashvars.firstname = "Nick"; 
    flashvars.lastname = "Danger"; 
    var params = {}; 
    params.quality = "high"; 
    params.bgcolor = "#ffffff"; 
    params.allowscriptaccess = "sameDomain"; 
    var attributes = {}; 
    attributes.id = "TestProject"; 
    attributes.name = "TestProject"; 
    attributes.align = "middle"; 
    //参数说明：embedSWF("SWF路径","嵌入的div的id","宽度","高度","SWF的版本号","player产品安装swf","给SWF的参数")
    swfobject.embedSWF( 
        "FlashVarTest.swf", "flashContent", "100%", "100%", swfVersionStr, 
        xiSwfUrlStr, flashvars, params, attributes); 
    swfobject.createCSS("#flashContent", "display:block;text-align:left;"); 
</script>

• 采用<object/>标签

<object id='mySwf' classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' height='100%' width='100%'>
        <param name='src' value='FlashVarTest.swf'/>
        <param name='flashVars' value='firstname=Nick&lastname=Danger'/>
        <embed name='mySwf' src='FlashVarTest.swf' height='100%' width='100%' flashVars='firstname=Nick&lastname=Danger'/>
    </object>

• flashContent 是一个div

<div id="flashContent">
    <p>
    当浏览器没有安装FlashPlayer的时候，显示此内容。（PS:一般在这里面加上FlashPlayer下载提示和下载地址（可以自定义内网地址））
    </p>
    <p>
    To view this page ensure that Adobe Flash Player version 
    ${version_major}.${version_minor}.${version_revision} or greater is installed. 
    </p>
    <script type="text/javascript"> 
    var pageHost = ((document.location.protocol == "https:") ? "https://" : "http://"); 
    document.write("<a href='http://www.adobe.com/go/getflashplayer'><img src='" 
            + pageHost + "www.adobe.com/images/shared/download_buttons/get_flash_player.gif' alt='Get Adobe Flash player' /></a>" ); 
    </script> 
</div>

HTML 往SWF中传参数

• SWObject方式

    var flashvars = {}; 
    flashvars.firstname = "Nick"; 
    flashvars.lastname = "Danger"; 
    swfobject.embedSWF( 
        "FlashVarTest.swf", "flashContent", "100%", "100%", "", 
        "", flashvars,{},{}); 

• object标签方式

<object id='mySwf' classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' height='100%' width='100%'>
        <param name='src' value='FlashVarTest.swf'/>
        <!-- 传参数，必须满足URL编码格式 -->
        <param name='flashVars' value='firstname=Nick&lastname=Danger'/>
        <embed name='mySwf' src='FlashVarTest.swf' height='100%' width='100%' flashVars='firstname=Nick&lastname=Danger'/>
    </object>

• 通用的URL传参方式

//swfobject
swfobject.embedSWF(
               "FlashVarTest.swf?firstname=Nick&lastname=Danger",
               "flashContent", "100%", "100%",
               swfVersionStr, xiSwfUrlStr,
               flashvars, params, attributes);
//<object>
<object id='mySwf' classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' height='100%' width='100%'>
       <param name='src' value='FlashVarTest.swf?firstname=Nick&lastname=Danger'/>
</object>

• 服务器页面动态传参
• JSP

<%
   String fName = (String) request.getParameter("firstname");
   String lName = (String) request.getParameter("lastname");
%>
<script type="text/javascript">
           var swfVersionStr = "0";
           var xiSwfUrlStr = "";
           var flashvars = {};
           flashvars.firstname = "<%= fName %>";
           flashvars.lastname = "<%= lName %>";
           var params = {};
           params.quality = "high";
           params.bgcolor = "#ffffff";
           params.allowscriptaccess = "sameDomain";
           var attributes = {};
           attributes.id = "FlashVarTest";
           attributes.name = "FlashVarTest";
           attributes.align = "middle";
           swfobject.embedSWF(
               "FlashVarTest.swf", "flashContent",
               "100%", "100%",
               swfVersionStr, xiSwfUrlStr,
               flashvars, params, attributes);
       </script>

• php

<?php 
    @ $fName = $_GET['firstname']; 
    @ $lName = $_GET['lastname']; 
?> 
<script type="text/javascript"> 
    var swfVersionStr = ""; 
    var xiSwfUrlStr = ""; 
    var flashvars = {}; 
    flashvars.firstname = "<?php echo $fName; ?>" 
    flashvars.lastname =  "<?php echo $lName; ?>" 
    var params = {}; 
    params.quality = "high"; 
    params.bgcolor = "#ffffff"; 
    params.allowscriptaccess = "sameDomain"; 
    var attributes = {}; 
    attributes.id = "FlashVarTest"; 
    attributes.name = "FlashVarTest"; 
    attributes.align = "middle"; 
    swfobject.embedSWF( 
        "FlashVarTest.swf", "flashContent", 
        "100%", "100%", 
        swfVersionStr, xiSwfUrlStr, 
        flashvars, params, attributes); 
    swfobject.createCSS("#flashContent", "display:block;text-align:left;"); 
</script>

SWF 中获取参数

• 获取指定参数值
  FlexGlobals.topLevelApplication.parameters.firstname
• 通过for .. in遍历所有的属性名称和属性值

for (var att:String in FlexGlobals.topLevelApplication.parameters) {
      trace( att + ":" + FlexGlobals.topLevelApplication.parameters[att] );
 }

• Flex 中获取参数的完整示例

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
xmlns:s="library://ns.adobe.com/flex/spark" 
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
<fx:Script>
<![CDATA[
import mx.core.FlexGlobals;
protected function button2_clickHandler(event:MouseEvent):void
{
          log.text += "firstName:"+FlexGlobals.topLevelApplication.parameters.firstName +"\n";
}
protected function button3_clickHandler(event:MouseEvent):void
{
        log.text += "=============开始遍历flashvar对象========\n";
        for (var i:String in FlexGlobals.topLevelApplication.parameters) {
                        log.text += i + ":" + FlexGlobals.topLevelApplication.parameters[i] + "\n";
        }
        log.text += "=============结束遍历flashvar对象========\n";
}
