我有像这样的HTML代码
HTML:
<form id="online_booking" method="POST" action="book.php" name="former">
<div id="book_form">
<p>
<label for="z_name">Name:<span class="red"> *</span></label>
<input type="text" placeholder="ENTER NAME.." name="z_name" required>
</p>
<p>
<label for="z_email">EMAIL:<span class="red"> *</span></label>
<input type="email" placeholder="ENTER EMAIL.." name="z_email" required>
</p>
<p>
<label for="z_subject">PHONE:<span class="red"> *</span> </label>
<input type="tel" placeholder="ENTER PHONE.." name="z_subject" required>
</p>
</form>
和jQuery:
$(document).ready(function() {
$('#book_form').dialog({
autoOpen: true,
height: 375,
width: 350,
modal: true,
buttons: [
{
text: "Cancel",
click: function() {
$(this).dialog("close");
}},
{
text: "Submit",
click: function() {
$('#online_booking').submit();
}}
]
});
});
如何验证HTML字段,因为表单上没有提交按钮?在 在jQuery代码中,我创建了2个按钮(取消和提交),但是如果没有正确输入HTML字段,我不知道如何停止提交表单。

您只需通过创建自己的验证函数来更改click
函数,该函数将返回true
或false
:
click: function ()
{
if ( someValidationFunction() )
$('#online_booking').submit();
}

这是一个基本的例子,但是如果你只是检查空白就可以了:
$(document).ready(function () {
$('#book_form').dialog({
autoOpen: true,
height: 375,
width: 350,
modal: true,
buttons: [
{
text: "Cancel",
click: function () {
$(this).dialog("close");
}
},
{
text: "Submit",
click: function () {
if (valid()) { //Check for Valid
$('#online_booking').submit();
}
else {
alert("Invalid");
}
}
}
]
});
});
var valid = function () { //Validation Function - Sample, just checks for empty fields
var valid;
$("input").each(function () {
if ($(this).val() === "") {
var a = $(this).val();
valid = false;
}
});
if (valid !== false) {
return true;
}
else {
return false;
}
}
