你好
我安装了安装在某个位置qty = evt.target.value;
//create a string
var obj = firebase.firestore.FieldPath(item).quantity;
//str = item + '.quantity';
//obj[str] = qty;
// var myUpdate = {};
// myUpdate['${item}.quantity'] = qty;
//var obj = [item]["quantity:"] = qty;
console.log("item is " + item);
//var obj = {"'" + item + "'.quantity" : qty};
//obj[item]["quantity"] = qty;
console.log("qty is " + qty);
orderRef.update (
{obj:2}
//{"quantity":qty}
//[item + '.quantity']: qty
//[`favorites.${key}.color`] = true
// ['${item}.quantity'] : qty
//[`hello.${world}`]:
//{[objname]}.value = 'value';
//['favorites.' + key + '.color']: true
//[item]["quantity"] = qty // err:reqd 2 args
//item["quantity"] = qty
//"favorites.color": "Red"
//{"`item`.quantity": qty}
//{"quantity":qty}

的postgresql服务器。但是当我转到Applications/Postgres93.app/Contents
时,没有applications
文件夹吗?是否有任何隐藏文件?
能否请您告诉我如何通过Finder查找文件夹?
