我剛創建了一個按鈕的簡單輸入字段，並添加了對此的驗證。當我單擊不帶值的apply按鈕時，它應顯示錯誤框，並且不應在if(ack)條件內進入。
在我的代碼錯誤框正在顯示，但之後它進入if(ack)方法，即使沒有values.What我做錯了嗎？驗證在jquery中無法正常工作
function applyLeave() {
debugger
var ack = true
$('.required').each(function() {
if ($(this).val() == '') {
$(this).addClass('inputBorder')
var ack = false
}
})
if (ack) {
var newLeaveDetails = {};
newLeaveDetails = {
a: $('#levType').val(),
b: $('#levFrom').val(),
c: $('#levTo').val(),
d: $('#levDuration').val(),
e: $('#uploadDoc').files[0],
g: $('#LevReason').val(),
}
console.log(newLeaveDetails)
var ajaxObj = JSON.stringify({
LeaveDetails: newLeaveDetails
});
console.log(ajaxObj)
$.ajax({
type: 'POST',
url: '',
async: true,
data: ajaxObj,
contentType: 'application/json',
success: function() {
$(".success").html("Leave applied successfully!");
$('.success').show();
window.setTimeout(function() {
window.location.href = '/leave/employeeleavelist'
}, 1000);
},
error: function() {
alert("Try Again")
}
})
}
}.inputBorder {
border-color: red !important;
