这只是一个简单的正则

结合这个类才显出威力
<SCRIPT LANGUAGE="JavaScript">
<!--
function fileName(fname){
if(typeof(fname) != "string" || fname == "")
throw(new Error(-1, '创建类实例的时候请把类实例的引用变量名传递进来！'));

//【property】
this.name = fname;
this.filename = '';
this.basename = '';
this.folder = '';
this.extension = '';
}

fileName.prototype.getBaseName = function(filename){
gpos=filename.search(/\//i);
if (gpos>-1){
basename = filename.substr(gpos+1);
this.folder += filename.substr(0,gpos+1);
this.getBaseName(basename);
}
else {
this.basename = filename;
this.getExtension(filename);
}
}//end func getBaseName

fileName.prototype.getExtension = function(basename){
expos=basename.search(/\./i);
if (expos>-1){
ext = basename.substr(expos+1);
this.getExtension(ext);
}
else {
this.extension = basename;
}
}

fname='images/stories/.thumb_bangongjiaju/2004122219309642pf-020.a.gif';
fe = new fileName("fe");
fe.filename = fname;
fe.getBaseName(fname);
alert(fe.basename +"\n"+ fe.folder +"\n"+ fe.extension);

//alert(r);
