如何要求在命令行中問題的NodeJS

Question

在Ruby中，我們可以做這樣的

print "How old are you? " 
age = gets.chomp() 
print "How tall are you? " 
height = gets.chomp() 
print "How much do you weigh? " 
weight = gets.chomp() 

puts "So, you're #{age} years old, #{height} tall and #{weight} heavy." 

會喜歡這個

，但如何做到這一點的NodeJS中？

Answer 1

從readline Node.js的資料爲準：

var readline = require('readline'); 

var rl = readline.createInterface({ 
    input: process.stdin, 
    output: process.stdout 
}); 

rl.question("What do you think of node.js? ", function(answer) { 
    console.log("Thank you for your valuable feedback:", answer); 

    rl.close(); 
});
