我的哈希看起来像这样
%hIDSet = (
'TSASD2' => {
'country' => 'US',
'newid' => 'IMRAN',
'oldid' => 'TSASD4'
}
'TS767' => {
'country' => 'DE',
'newid' => 'B90LKT',
'oldid' => '432553'
},
);
当我做
my $sID = "TSASD2";
delete $hIDSet{$sID};
我得到的输出是
%hIDSet = (
'TSASD2' => {},
'TS767' => {
'country' => 'DE',
'newid' => 'B90LKT',
'oldid' => '432553'
},
);
我的问题是为什么没有完全删除 ID?
