String 操作
String nbbms ="col_1_1_1_1,col_2_2_2_@,";
@ 实现将最后一个逗号去掉:从第一个字符串到最后一个逗号之前的字符串截取【java】
String nbbm = nbbms.substring(0, nbbms.lastIndexOf(","));
@ 将col_2_2_2_@,从字符串中删掉【javacrpit】
var str ="'Hisense_0000000000000000011','Hisense_0000000000000000010'"
var newNBBM = str .replace(("'Hisense_0000000000000000011',"),"");
document.write(newNBBM)
