我如何随机查询其中一行?例如:
var rand = Math.floor(Math.rand() * 2);
Rows.find({ "row" + rand: "sup" }, function (err, result) {
if (err) {
console.log(err);
}
console.log(result);
});

这段代码出错了 SyntaxError: Unexpected token +
试试吧
var rand = Math.floor(Math.rand() * 2);
var objFind = {};
objFind["row" + rand] = "sup";
Rows.find(objFind, function (err, result) {
if (err) {
console.log(err);
}
console.log(result);
});
