解决方案
解决方案二：
alpha是来设置透明度的,它的基本属性是filter：alpha（opacity，finishopacity，style，startX，startY，finishX，finishY）.opacity代表透明度数,选值0-100,0是完全透明,100是不透明.finishopacity用来设置结束时的透明度,以达到渐变效果.取值范围也是0-100.style指渐变类型,0是无变化,1是线行渐变,2是放射渐变,3是X型渐变.参考http://hi.baidu.com/ouanan/blog/item/c9c377c43eaee4ce38db4943.htmlhttp://hi.baidu.com/ate0611/blog/item/de9f79fabcc146839e5146ca.html
