我有一個腳本，它從一個句子中創建一個單詞陣列，然后將每個字母大寫，每當我運行腳本時，我都會遇到 sintax 錯誤。這是與輸入和輸出框相關的所有 JavaScript。
function validateForm() {
var addressInput = regForm.addressBox.value;
var postCode = regForm.postCode.value;
var townInput = regForm.townBox.value;
var addressArray = addressInput.split(" ");
var townArray = townInput.split(" ");
for (let i = 0; i < addressArray.length; i ) {
var addressArray[i] = addressArray[i][0].toUpperCase() addressArray[i].substring(1);
}
var addressCap = addressArray.join(" ");
for (let i = 0; i < townArray.length; i ) {
var townArray[i] = townArray[i][0].toUpperCase() townArray[i].substring(1);
}
var townCap = townArray.join(" ");
if (addressCap > 1 ) {
if (townCap > 1) {
if (postCode == 4) {
document.getElementById('addressOutput').innerHTML = "Your address is: " addressCap ", " townInput ", " postCode;
}
if (postCode != 4) {
document.getElementById('addressOutput').innerHTML = "Please fill out the post code box";
}
}
if (townCap < 1) {
document.getElementById('addressOutput').innerHTML = "Please fill out the town box";
}
}
if (addressCap < 1) {
document.getElementById('addressOutput').innerHTML = "Please check your address for errors";
}
}
錯誤是針對iinaddressArray[i]的，townArray[i]
我覺得它非常簡單，但我很難過。
uj5u.com熱心網友回復：
var addressArray[i] =不是有效的語法。
洗掉var, 因為您沒有宣告變數：
addressArray[i] = addressArray[i][0].toUpperCase() addressArray[i].substring(1);
