从零开始学习Node.js系列教程四：多页面实现的数学运算示例，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
本文实例讲述了Node.js多页面实现的数学运算。分享给大家供大家参考，具体如下：
app-node.js
404,{'Content-Type': 'text/plain'});
res.end("bad URL" + req.url);
}
});
server.listen(http_port);
console.log('listening to http://localhost:3000');
htutil.js
"].join('\n');
}
exports.page = function(title,navbar,content){
return ["
{title}","
{title}
","
"
].join('\n')
.replace(new RegExp("{title}","gm"),title)
.replace("{navbar}",navbar)
.replace("{content}",content);
}
home-node.js
Math Wizard"));
}
square-node.js
{a} squared = {sq}"
.replace("{a}",req.a)
.replace("{sq}",req.a * req.a))
: ""),"
Enter numbers to see its square
","
"
].join('\n'))
);
}
factorial-node.js
{a} factorial = {fact}"
.replace("{a}",req.a)
.replace("{fact}",math.factorial(Math.floor(req.a))))
: ""),"
Enter numbers to see its factorial
","
"
].join('\n'))
);
}
mult-node.js
{a} * {b} = {result}"
.replace("{a}",req.a)
.replace("{b}",req.b)
.replace("{result}",req.a * req.b))
: ""),"
Enter numbers to mutiply
","
"
].join('\n'))
);
}
fibo-node.js
{a} fibonacci = {fibo}"
.replace("{a}",Math.floor(req.a))
.replace("{fibo}",math.fibonacci(Math.floor(req.a))))
: ""),"
Enter numbers to see its fibonacci
","
"
].join('\n'))
);
}
fibo2-node.js
{a} fibonacci = {fibo}"
.replace("{a}",a)
.replace("{fibo}",fiboval))
: ""),""
].join('\n'))
);
}
exports.get = function(req,res){
if (!isNaN(req.a)){
math.fibonacciAsync(Math.floor(req.a),function(val){
sendResult(req,Math.floor(req.a),val);
});
}else {
sendResult(req,NaN,NaN);
}
}
math.js
希望本文所述对大家nodejs程序设计有所帮助。
