.toFixed는 하나의 양식에서만 작동하며 모두 3이 아닙니다.

Question

나는 JavaScript 계산기를 만든 곳에서 작업하고 있으며, 페이지에서 3을 모두 사용해야합니다. toFixed (2) 내 첫 번째 양식에. .toFixed (2)를 사용해도 다른 두 형식은 여전히 ​​소수점을 표시합니다. 어떤 아이디어

<script type="text/Javascript">  
// Begin calculations 
function resetCalc() { 
document.forms[0].elements[1]=""; 
} 

function calcRect() { 
if(validNumber(document.getElementById('length'), 'length') == true) {  
    if(validNumber(document.getElementById('width'), 'width') == true) { 
     var length = (document.getElementById('length').value) 
     var width = (document.getElementById('width').value) 

     var prodRect = (length * width/9) .toFixed(2) 

     document.getElementById('ansRect').value = prodRect 
     } 
    } 
} 
function calcCirc() { 
if(validNumber(document.getElementById('diameter'), 'diameter') == true) { 
    var diameter = (document.getElementById('diameter').value) 

    var prodCirc = (diameter/2) * (diameter/2) * 3.14 /9 .toFixed(2) 
    document.getElementById('ansCirc').value = prodCirc 
    } 
} 

function calcTria() { 
if(validNumber(document.getElementById('base'), 'base') == true) { 
    if(validNumber(document.getElementById('height'), 'height') == true) { 
     var base = (document.getElementById('base').value) 
     var height = (document.getElementById('height').value) 

     var prodTria = (base * .5) * height/9 .toFixed(2) 
     document.getElementById('ansTria').value = prodTria 
     } 
    } 
} 
// End Calculations 

// BEGIN Validate Values entered 
//Requires field that contians value being evaluated 
function validNumber(varInput, fieldName) { 

if (varInput.value == null) { 
     alert('Please enter a value for the ' + fieldName + ' field'); 
     varInput.focus(); 
     return false; 
    } 

if (IsNumeric(varInput.value) == false) { 
     alert('Please enter only numbers or decimal points in the ' + fieldName + ' field'); 
     varInput.focus(); 
     return false; 
    } 

return true; 
} 
// END Validation 

// check for valid numeric strings  
function IsNumeric(strString) { 
    var strValidChars = "."; 
    var strChar; 
    var blnResult = true; 

    if (strString.length == 0) return false; 

    // test strString consists of valid characters listed above 
    for (i = 0; i < strString.length && blnResult == true; i++) 
     { 
     strChar = strString.charAt(i); 
     if (strValidChars.indexOf(strChar) == -1) 
     { 
     blnResult = false; 
     } 
     } 

    return blnResult; 
} 
// 
</script> 

그리고

당신은 당신이 처음에했던 것처럼 두 번째 두 함수의 식을 괄호로 할 필요가

Answer 1

html로 : 여분의 괄호없이

var prodTria = ((base * .5) * height/9).toFixed(2) 

, 저것 안에 개조되고 있던 모두는 9이었다.
