FlashObject.js去虚框、传参数、获取URL参数
最简单的方法就是升级你的Dreamweaver到8.02或者更高版本,
新版本可以自动转化插入FLASH脚本,打开你带有FLASH虚线框的文件后会弹出如图窗口,
确认后,默认在网站根目录生成Scripts文件夹,AC_RunActiveContent.js文件,此后打开转化后的页面就不带虚线框.
一、去除虚框 内联参数
<div id="flashcontent" align="center">
</div>
<script type="text/javas
var so = new
SWFObject("images/logo8.swf", "flashcontent", "468", "60", "7",
"#000000");
// swf路径
名称 宽 高 flash版本 背景颜色
so.addParam("wmode",
"transparent"); //背景透明
so.write("flashcontent"); //相同
</script>
FLASH内联参数可选参数有：
useExpressInstall: 快速升级flash player
值为ture/false;
quality:播放品质，默认为"high";
xiRedirectUrl:指定完成(useExpressInstall)快速升级player后的定向网址。
redirectUrl：指定flash
player版本不正确的定向网址。
detectKey：flash检测的地址参数，默认为detectflash。如：要不检测flash，可以在网址后面加上?detectflash=false。
更多的的参数请参照Macromedia的详细介绍：http://www.macromedia.com/cfusion/knowledgebase/index.cfm?id=tn_12701
经W3C验证，此代码通过。
二、Flashvars变量设置
一般的是通过Flashvars来给flash条件变量：
<param
value="variable1=value1&variable2=value2&variable3=value3">
而FlashObject后的变量设置为:
<script
type="text/javas
var fo = new FlashObject("movie.swf",
"mymovie", "200", "100", "7", "#336699");
fo.addVariable("variable2", "value2");
fo.addVariable("variable3", "value3");
fo.write("flashcontent");
</script>
这样设置后，所有的变量就马上传到flash的_root上了。
注意：JS跟FLASH通信是以字符串传递的，因此对于Number型变量FLASH端需要做类型转换。
三、获取URL网址串的参数
例如网址：http://www.example.com/page.html?variable1=value1&variable2=value2
你可以通过以下方法来把上面的参数传递给flash。
<script
type="text/javas
var fo = new FlashObject("movie.swf",
"mymovie", "200", "100", "7", "#336699");
fo.addVariable("variable1", getQueryParamValue("variable1"));
fo.addVariable("variable2", getQueryParamValue("variable2"));
fo.write("flashcontent");
</script>
四、Flash
player的快速安装功能
FlashObject完全支持Flash
Player的快速安装功能。通过在flash的第一帧添加一段AS代码就可以轻松达到检测用户Flash
Player版本，并提示更新的功能。expressinstall.as代码如下：
var ExpressInstall =
new ExpressInstall();
if (ExpressInstall.needsUpdate) {
var upgradeMsg =
attachMovie("upgradeMsg_src", "upgradeMsg", 1);
upgradeMsg._x = Stage.width /
2;
upgradeMsg._y = Stage.height /
2;
upgradeMsg.upgradeBtn.on
ExpressInstall.init();
}
stop();
}
