Memasukkan perkataan mengakibatkan ralat NaN untuk titik data

Question

Apabila saya menaip perkataan, ini menunjukkan kepada saya ralat dengan NaN dalam makluman. Mesej kejayaan menunjukkan nilai yang betul, tetapi amaran menunjukkan ralat NaN. points 和 totalPoints Diisytiharkan skop fungsi luar

   var wordList = ["jalapeno", "nopal", "jalap", "paeon", "panel", "pelon", "penal", "plena", "pleon", "plane"]

Answer 1

Anda tidak sekali-kali menyimpan nilai mata anda ke dalam nilai totalPoints, jadi totalPoints tidak boleh disusun. Paling penting, anda perlu meletakkan pembolehubah storan di luar skop fungsi. Dalam kes anda, anda hanya menetapkan totalPoints kepada 0 setiap kali anda memanggil fungsi tersebut.

Jadi penyelesaiannya ialah:

        var totalPoints = 0; // initialize total points variable
        let wordList = ["test", "test2", "test3", "test4", "testtest"] // Changed
        let result = [] // Changed
        
        // Define click function for enter-btn
        $('#enter-btn').click(function() {   
          let points = 0; // Changed
          let wordInput = document.getElementById("inputTxt") // Changed
          var word = wordInput.value.trim(); // Changed
          var centerLetter = $('.hive-cell.center .cell-letter').text();

          // functions
          var notEmpty = function(message) { 
              $('.sb-message-box').addClass('error-message').text(message); 
                  // $('.sb-hive-input-content').addClass('not-empty').text(message); 
              setTimeout(function() {
                  $('#word-input').val('');
                  // $('.sb-hive-input-content').removeClass('not-empty').text('');
                      $('.sb-message-box').removeClass('error-message').text('');
              }, 1000); 
          } 

          var hasError = function(message) { 
              $('.sb-message-box').addClass('error-message').text(message);
                  $('.sb-hive-input-content').addClass('has-error').text(message); 
              setTimeout(function() {
                  $('#word-input').val('');
                      $('.sb-hive-input-content').removeClass('has-error').text('');
                          $('.sb-message-box').removeClass('error-message').text('');
