//搜索pno1出现的位置，然后截取从位置的下一个位置起到最后
var pno2 = pnos.substr(addr+pno1.length, pnos.length - (addr + pno1.length));
//去掉逗号和引号

var pnos = "'F002','F001','F003','F004',";
var pno1 = "'F002'";
var pno2=""
var parray2=new Array
parray1=pnos.split(",")
for(i=0;i<parray1.length;i++){
if (pno1!=parray1[i])
parray2[parray2.length]=parray1[i]
}
document.writeln(parray2.join(","));
