jsp里~~

action里~~

public String deleteRecord() throws Exception {//删除记录

idSting=idSting.substring(0,idSting.length()-1);//待删除记录若干id的字符串，逗号分隔
testService.delete(idSting);
return SUCCESS;
}
自己写滴~~功能上实现了~~没进行服务器端校验~~先记录下~以后再改进~~
另~
获得form中checkbox个数可以用 testForm.delid.length ~~
但要注意~
当只有一个checkbox时~ testForm.delid.length 滴值为undefined~
就是说~当只有一条记录时无法删除~~
所以还是乖乖用 document.getElementsByName("delid") ~然后用.length获得个数~~
再另~~
百度空间文章滴排版真杯具~贴进来滴代码滴缩进被无视了~
