最近学vml：：cakepie.innerHTML="<v:shape id=cake"+(i+1)+"type=#Cake_3D"+
" style=position:absolute;left:"+(_left + Height / 8)+"px;top:"+(_top + Height / 24)+"px;WIDTH:"+Height+"px;HEIGHT:"+Height+"px;rotation:"+rotates+";z-index:"+zIndex+" adj="+adjs+",0"+
"stroked=false fillcolor="+this.Cakes[i][2]+" onclick=moveCake(cake"+(i+1)+",rec"+(i+1)+") onmouseover=moveover(\""+this.Cakes[i][0]+"\","+this.Percent[i]+") onmouseout=moveout()>"+
"<v:fill opacity=60293f color2=fill lighten(120) o:opacity2=60293f rotate=t angle=-135 method=linear sigma focus=100% type=gradient/>"+
"<o:extrusion v:ext=view on=t backdepth=16 rotationangle=60 viewpoint=0,0viewpointorigin=0,0 skewamt=0 lightposition=-50000,-50000 lightposition2=50000/>"+
"</v:shape>";
其中红色部分的moveover函数第一个参数是 cake的名字，由于本身在一个双引号的字符串里面， 开始时候是这么写的：onmouseover=moveover("+this.Cakes[i][0]+","+this.Percent[i]+")
在moveover函数中怎么也获取不到this.Cakes[i][0]的值 。 后来在两边加了单引号onmouseover=moveover(‘"+this.Cakes[i][0]+","+this.Percent[i]+") 还是不行，最后 用转译斜杠+双引号（蓝色部分）解决了
