Javascript函數問題

我想讓用戶輸入一個數字，然後輸入另一個數字，該數字將開始輸入第一個數字的乘法表，並繼續遞增1，直到達到用戶提示的最後一個數字...Javascript函數問題

例如，如果用戶是要輸入10，則如圖1所示，然後如圖10所示，輸出將如下所示：

10 * 1 = 10
10 * 2 = 20
10 * 3 = 30
...
10 * 10 = 100

我在做什麼錯？

感謝您的幫助！

function multiplierz(numberMultiplied, amountToMultiplyFirst, amountToMultiplyLast) 
    { 


     while (isNaN(numberMultiplied) = true || isNaN(amountToMultiplyFirst) = true || isNaN(amountToMultiplyLast) = true) 
     { 
      alert("YOU DID NOT ENTER ONLY NUMBERS. WAY TO GO DUMMY."); 
      var numberMultiplied = prompt("Please Enter The Number to Multiply"); 
      var amountToMultiplyFirst = prompt("Start multiplying by which number?"); 
      var amountToMultiplyLast = prompt("End multiplying by which number?"); 
     } 
     for (counter = amountToMultiplyFirst; counter <= amountToMultiplyLast; counter++) 
      { 
       document.write(numberMultiplied + " * " + counter + " = " + numberMultiplied * counter + "<br />"); 
      } 
    } 

    //Begin Program Below 


     multiplierz(prompt("Please Enter The Number to Multiply"),prompt("Start multiplying by which number?"),prompt("End multiplying by which number?")); 
</script>

它不運行：P – bruchowski 2011-04-18 04:10:26

你需要在你的while條件使用==，而不是=：

while (isNaN(numberMultiplied) == true || isNaN(amountToMultiplyFirst) == true || isNaN(amountToMultiplyLast) == true) 
{ 
    ... 
}

，你沒有考慮amountToMultiplyFirst簡單的事情應該比amountToMultiplyLast少:-)

你isNan(numberMultiplied) = true拋出一個錯誤。在JavaScript中，=運算符用於分配。

只是做

while (isNaN(numberMultiplied) || isNaN(amountToMultiplyFirst) || isNaN(amountToMultiplyLast))
