当然了，你去抄人家主动技的，肯定target不行

'step 0'
player.chooseTarget();
'step 1'
if(result.bool){
player.viewHandcards(result.targets[0]);
}

现在依旧报错，而且是回合开始便报错，代码如下：
skill={
audio:"0",
trigger:{
player:"phaseZhunbeiBegin",
},
filter:function (event,player){
return current.countCards('h')!=0;
},
forced:true,
content:function (){
'step 0'
player.chooseTarget(get.prompt2('选择一名其他角色并观看其手牌'),function(card,player,target){
return player!=target&&target.countCards('h')!=0;
});
'step 1'
if(result.bool){
event.target=result.targets[0];
player.viewHandcards(result.targets[0]);
player.chooseControl('ok');
}
else {
event.finish();
}
},
}

现在可以选择目标了，也能正常观看手牌了，但是在观看完后点击确定尝试结束观看就会报错，现在代码如下：
skill={
audio:"0",
trigger:{
player:"phaseZhunbeiBegin",
},
content:function (){
'step 0'
player.chooseTarget(get.prompt2('选择一名其他角色并观看其手牌'),function(card,player,target){
return player!=target&&target.countCards('h')!=0;
});
'step 1'
if(result.bool){
event.target=result.targets[0];
player.viewHandcards(result.targets[0]);
player.line(target);
var content=[get.translation(target)+'的手牌',cards];
game.log(player,'观看了',target,'的手牌');
player.chooseControl('ok').set('dialog',content);
}
else {
event.finish();
}
},
}

有一张卡牌叫知己知彼
