--------------------------------------网扑的frame的代码.function mainCenterClick(){
try{
if(main.cols!="6,*") {
main.cols="6,*";
//mainCenter.document.getElementById("ImgArrow").src="http://txt.mop.com/dzh/centerframe/al2.gif";
}else{
main.cols="503,*"
//mainCenter.document.getElementById("ImgArrow").src="http://txt.mop.com/dzh/centerframe/al2.gif";
}
/*
if(main.cols=="503,*") {
main.cols="6,*";

}else{
main.cols="503,*"
//mainCenter.document.getElementById("ImgArrow").src="http://txt.mop.com/dzh/centerframe/al2.gif";
}

leftFrame.centerClick();
}catch (e){}
}
----------------------------这个JS函数就是点击那个图片后触发的函数
他做的那种效果是在左边FRAME加了一个TABLE,然后在靠近frame边框的地方加了一个图片.
