在调用引导程序之前先验证引导程序模式

Question

我是Modals和jQuery的新手。我需要一些帮助。我有一个表单，我使用的是LiveValidation库，也有Bootstrap Modal。我使用Modal来显示表单中的用户输入，并有确认提交按钮。

当前设置为。当用户填写所有字段时，模态将出现并显示用户的输入并有确认按钮提交。现在，我添加了验证，并且出现了一些逻辑错误或不正确的代码安排？

当用户没有填满所有的字段验证开始（我想要的），但我的莫代尔也出现了。如果点击Modal内的提交按钮，它将不会提交，因为用户没有填好表格中的所有字段。

我只想让我的Modal不显示，如果所有的字段没有填写或验证。

我在同一时间调用Validation和Modal的表单上提交了按钮，我知道它是原因。我只需要帮助如何安排或重组我的代码？

这里是我的HTML

这里是我的验证

<script type="text/javascript"> 
function checkInput() 
{ 
    var lastname = new LiveValidation('lastname', {onlyOnSubmit: true }); 
    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，将得到来自表单的输入，并将其复制到模式

<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>

你如果您的验证失败，则已经返回false，因此您只需在显示模态之前检查它（返回tr如果它通过）。不要直接从提交中调用checkInput()，而应调用另一个调用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'); 
    } 
}
