NodeJS Express中的分頁方法

Question

我有以下代碼：

app.post('/pepe/query/', function(req, res) {
  var query = "SELECT * FROM mutations";
  if (req.body.start.length !== 0) { //From an HTML form
    query = query + " WHERE pos>=" + req.body.start;
  }
  app.get('/pepe/query/:number', function(req2, res2) {
    var pages = 10 * req.param2("number") - 10;
    query2 = query + " LIMIT " + pages + ", 10";
    if (req.body.output == 1) {
      pool.query(query2, function select(error, results, fields) {
        res.render('index.html',{data:results, error:null});
      });
    } else if (req.body.output == 2) {
      query2 = "SELECT count(*) FROM (" + query + ") AS table1";
      pool.query(query2, function select(error, results, fields) {
        res.send(results);
      });
    }
  });
});

但是，這種方法不起作用，因為我通過POST將信息從表單發送到/pepe/query ，但它不起作用。

我的目標是例如轉到/pepe/query/3 ，然后轉到第3頁（結果21-30）。

像這樣：

app.get('/pepe/query/', function(req, res) {
    var start = req.query.start;
    var number = req.query.number;
    //Logic here.
    res.send(results);
});

<form method="GET" action="/pepe/query/">
   <input name="start" type="text" id="search" />
   <input name="number" type="text" id="number"  />
</form>
