我是Modals和jQuery的新手。我需要一些帮助。我有一个表单，我正在使用LiveValidation库，我也有Bootstrap Modal。我正在使用Modal从表单中显示用户输入并有一个确认提交按钮。
目前的设定是。当用户填写所有字段时，将显示Modal并显示用户的输入并具有要提交的确认按钮。现在，我添加了一个验证，我遇到了一些逻辑错误或不正确的代码安排？
当用户没有填写所有字段时，验证开始（我想要），但我的Modal也出现了。如果单击模态内的提交按钮，则不会提交，因为用户尚未填写表单中的所有字段，这是正常的。
如果所有字段都没有填写或验证，我只希望我的模态不显示。
我在表单上提交了同时调用验证和模态的按钮，我知道这是原因。我只是需要帮助如何安排或重组我的代码？
这是我的HTML

这是我的验证

function checkInput()
{

lastname.add( Validate.Presence );
var firstname = new LiveValidation( 'firstname', {onlyOnSubmit: true } );
firstname.add( Validate.Presence );
var island = new LiveValidation( 'island', {onlyOnSubmit: true } );
island.add( Validate.Presence );
var region = new LiveValidation( 'region', {onlyOnSubmit: true } );
region.add( Validate.Presence );
var province = new LiveValidation( 'province', {onlyOnSubmit: true } );
province.add( Validate.Presence );
var city = new LiveValidation( 'city', {onlyOnSubmit: true } );
city.add( Validate.Presence );
var barangay = new LiveValidation( 'barangay', {onlyOnSubmit: true } );
barangay.add( Validate.Presence );
var address = new LiveValidation( 'address', {onlyOnSubmit: true } );
address.add( Validate.Presence );
var gender = new LiveValidation( 'gender', {onlyOnSubmit: true } );
gender.add( Validate.Presence );
var birthdate = new LiveValidation( 'birthdate', {onlyOnSubmit: true } );
birthdate.add( Validate.Presence );
var automaticOnSubmit = lastname.form.onsubmit;
lastname.form.onclick = function(){
var valid = automaticOnSubmit();
if(valid)alert('The form is valid!');
return false;
}
}
</script>
这里只是一个脚本，它将从表单中获取输入并将其复制到模态
<script type="text/javascript">
/* Get input and show to modal */
$('#submitBtn').click(function() {
/* when the button in the form, display the entered values in the modal */
$('#modal_lastname').html($('#lastname').val());
$('#modal_firstname').html($('#firstname').val());
$('#modal_island').html($('#island2').val());
$('#modal_region').html($('#region2').val());
$('#modal_province').html($('#province2').val());
$('#modal_city').html($('#city2').val());
$('#modal_barangay').html($('#barangay2').val());
$('#modal_address').html($('#address').val());
$('#modal_gender').html($('#gender').val());
$('#modal_birthdate').html($('#birthdate').val());
});
$('#submit').click(function(){
/* when the submit button in the modal is clicked, submit the form */
$('#formfield').submit();
});
</script>
答案 0 :(得分：3)
如果验证失败，您已经返回false，因此您只需在显示模态之前检查它（如果通过则返回true）。不要直接从提交中调用checkInput()，而是调用另一个在其中调用checkInput()的函数。
<input type="button" name="btn" value="Submit" id="submitBtn" class="btn btn-default" onclick="submitForm();";/>
function submitForm() {
var valid = checkInput();
if (valid) {
$('#confirm-submit').modal('show');
}
}
