對於這行代碼被識別爲一個的Javascript意外意外標識符
一些奇怪的原因此特定線是
`Unexpected identifier`
bmr = 66 + (6.23 * weightInlbs) + (12.7 heightInInches) - (6.8 * age);
這是整個代碼
function metricComputation() {
var age = document.getElementById("age");
var weightInlbs = document.getElementById("weight");
var heightInInches = feetToInches(new Number(document.getElementById("heightinFt")) , document.getElementById("heightinIn"));
var bmr;
var gender = document.getElementById("gender");
if(gender === "male"){
bmr = 66 + (6.23 * weightInlbs) + (12.7 heightInInches) - (6.8 * age);
}
}
這是整個標記
