我想檢查頁面上的文本框是可見的,並驗證它們不是空的,我有一些隱藏的文本框,當用戶選擇某些項目。我試圖跳過這些隱藏的文本框,除非它們是可見的。我試圖這個代碼,但它仍然警告不可見的文本框沒有價值。通過頁面上的可見文本框循環jquery
的jQuery:
<script type="text/javascript">
$(function() {
$('#selected1').val("");
$('#selected2').val("");
$('select').change(function() {
if ($('#DDLHearAboutUs').val() === "Optional1") {
$('#OptionalTxt1').show();
} else {
$('#OptionalTxt1').hide();
}
if ($('#DDLProfession').val() === "Optional2") {
$('#OptionalTxt2').show();
} else {
$('#OptionalTxt2').hide();
}
});
});
function checkEmpty() {
var empty = false;
$('select').each(function() {
if ($(this)[0].selectedIndex === 0) {
empty = true;
}
});
$('form input:text:visible').each(function() {
if ($(this).val().length === 0) {
empty = true;
}
});
if (empty) {
alert('Please fill out all of the fields');
return false;
}
}
</script>

你在隱形文本框上放置一個類來隱藏它們嗎?嘗試搜索所有文本框幷包含一個if語句,該語句表示'沒有makeMeInvisible類'。 – Mark 2014-10-03 14:17:18
不,要隱藏它們我有另一個函數爲dropdownlist激發onchange,如果value = im查找的值,那麼它只是在文本框上執行.show()或.hide()。 – user3267755 2014-10-03 14:18:31
什麼叫' checkEmpty'? – j08691 2014-10-03 14:25:25
