私の姓と姓の入力フィールドをモーダルで検証したいと思います。空の場合は、「このフィールドは必須です！」というメッセージが表示されます。赤で色付けされています。モーダルでの入力フィールドの妥当性確認
私が直面している問題は、スクリプトがフィールドを検証していないことです。
助けてください。
$(document).ready(function() {
$('#btn').click(function(e) {
var fieldIDArray = [$('#firstName', '#lastName')];
var spanIDArray = [$('#firstNameRequired',
'#lastNameRequired')];
for (i = 0; i < fieldIDArray.length; i++) {
if (!fieldIDArray[i].val()) {
e.preventDefault();
fieldIDArray[i].closest('.form-group')
.removeClass('has-success').addClass(
'has-error');
spanIDArray[i].show();
} else {
fieldIDArray[i].closest('.form-group')
.removeClass('has-error').addClass(
'has-success');
spanIDArray[i].hide();
}
}
});
});.requiredField {
color: red;
