Flex获取URL中的参数

来源：互联网发布：软件数字证书认证中心编辑：程序博客网时间：2024/05/01 14:34

当页面通过URL来传递参数时(page.html?id=123&name=aaa),可以在包含swf的html网页中先用javascript从url中截取包含参数的字符串,以FlashVar的形式传给swf,而在Flex中可以直接使用this.parameters.参数名来获取参数的值.

Sample:

html页面代码:

<html>
    <body>
<script language=javascript>

function writeflashobject(parastr) {
    document.write("<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="550" height="400" id="FlashVars" align="middle"> ");
    document.write("<param name="allowScriptAccess" value="sameDomain" /> ");
    document.write("<param name="movie" value="useLib.swf" /> ");
    document.write("<param name="FlashVars" value=""+ parastr +"" /> ");
    document.write("<param name="quality" value="high" /> ");
    document.write("<param name="bgcolor" value="#ffffff" /> ");
    document.write("<embed src="useLib.swf" quality="high" bgcolor="#ffffff" width="550" height="400" name="FlashVars" align="middle" allowScriptAccess="sameDomain" FlashVars=""+ parastr +"" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />");
    document.write("</object>");
}
function getparastr() {
    var hrefstr,pos,parastr,para,tempstr1;
    hrefstr = window.location.href;
    pos = hrefstr.indexOf("?")
    parastr = hrefstr.substring(pos+1);
    return parastr;
}
var parastr = getparastr();
writeflashobject(parastr);

</script>
</body>
</html>
