Flex4如何给swf传参数

来源：互联网发布：如何下载windows 10 编辑：程序博客网时间：2024/06/06 12:27

基本上有3种方式：
1)通过URL查询字符串方式给swf传参数

URL如下:
http://localhost:8080/html2Swf/bin-debug/html2Swf.swf?myName=aa&myHometown=aa

2)通过URL查询字符串方式给swf的wrapper html页面传参数

URL如下:
http://localhost:8080/html2Swf/bin-debug/html2Swf.html#firstName=Nick&lastName=Danfffger

注意,第1中方式中用?, 第2中方式用#, 另外第2种方式里name/value对的分割符可以自定义,代码中解析时作出相应更改即可，详细资料可以参考Flex3帮助文档:

3)在对应的Wrapper html页面中静态配置，有两个地方可以配置：
位置1 var flashvars = {};

案例 var flashvars = {"myName":"Danger","myHometown":"Los%20Angeles_Flashvars"};

位置2

Java代码
          swfobject.embedSWF(                "${swf}.swf", "flashContent",                 "${width}", "${height}",                 swfVersionStr, xiSwfUrlStr,                 flashvars, params, attributes);
案例： 
Java代码
          swfobject.embedSWF(                "${swf}.swf?myName=aa&myHometown=bb", "flashContent",                 "${width}", "${height}",                 swfVersionStr, xiSwfUrlStr,                 flashvars, params, attributes);
综合案例 

按方式1和3传参数，只有上面的TitleWindow里面有值，其中方式3事实上就是不传参数，按方式2传参数，只有下面的TitleWindow里面有参数值. 
Java代码
