从散列中将密钥值写入文件

Question

我想将文件中的键值写为vals。我希望你能帮助我。谢谢。

File.open(resfile,'a+') do |f2|
  gname.each {|key,val| val.each {|x|   f2.write(x) f2.write("\t")} 
    f2.write("\n")}
end 

Answer 1

result = gname.map { |_key, val| val.join("\t") }.join("\n")
File.write(resfile, result)

Answer 2

我想你的意思是：

        if (this.config.lang != 'en'){
            console.log("in Translate");
            Promise.all([
                translate(alerts.description, {to: this.config.lang}),
                translate(alerts.expires, {to: this.config.lang}),
                translate(alerts.message, {to: this.config.lang})
            ]).then(function(results) {
                // results[0], results[1], results[2] contain the three results
                // use those three values in the code inside this callback
            })
        }
