具有弹出式图像引导4β的图像

Question

I改为使用modals.

我把这个网站改成了BS4测试版。在此页上，当您单击图像时，它应该会打开一个弹出或带有图像的模式。

​

<div class="row mb-2">
    <div class="col-lg-2 col-sm-3 col-xs-4">
       <a href="javascript:popUp('ltrs/bluewater.htm')"><img src="photos/logo/bluewater.jpg" class="thumbnail img-fluid" alt="Bluewater Resort &amp; Casino"></a> 
     </div>
     <div class="col-lg-2 col-sm-3 col-xs-4">
        <a href="javascript:popUp('ltrs/semhardrock.htm')"><img src="photos/logo/hardrock.gif" class="thumbnail img-fluid" alt="Hard Rock Hotel &amp; Casino" ></a>
    </div>
     <div class="col-lg-2 col-sm-3 col-xs-4">
        <a href="javascript:popUp('ltrs/trump.htm')"><img src="photos/logo/trump29.jpg" class="thumbnail img-fluid" alt="Trump 29 Casino"></a>
    </div>
     <div class="col-lg-2 col-sm-3 col-xs-4">
        <a href="javascript:popUp('ltrs/bestwestern.htm')"><img src="photos/logo/bestwestern.gif" class="thumbnail img-fluid" alt="Best Western"></a>
    </div>
     <div class="col-lg-2 col-sm-3 col-xs-4">
       <a href="javascript:popUp('ltrs/delsol.htm')"><img src="photos/logo/delsol.jpg" class="thumbnail img-fluid" alt="Casino Del Sol"></a>
    </div>
     <div class="col-lg-2 col-sm-3 col-xs-4">
        <a href="javascript:popUp('ltrs/ag.htm')"><img src="photos/logo/ag.jpg" class="thumbnail img-fluid" alt="Apache Gold Resort Casino"></a>
    </div>
</div>

​

我在页面底部列出了BS .js，在结束正文标记之前。

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

我做错了什么？这是过去的工作，当它是启动3。

Answer 1

似乎您的方法弹出在全局范围内不可用。

请参阅我的控制台中的错误：

​

我有这个错误，当我点击项目，如罗斯韦尔丰田。

另外，您在这个脚本上有一个错误：

    $(document).ready(function() {
      $("#submit-button").on('click', function(e) {
        e.preventDefault(); // Prevent form submission

       // you would need to set the following values from your form fields
       var name = $("#form_name").val();
       var email = $("#form_email").val();
       var phone = $("#form_phone").val();
       var message = $("#form_message").val();
       var dataString = 'surname='+ name + '&email=' + email + '&phone=' + phone + '&message=' + message;

       $.ajax({
         type: "POST",
         url: "contact.php",
         data: dataString,
         success: function() {
           $(".messages").html("Thank you for contacting me.  I will be in touch soon.").css("visibility", "visible");
           $("#submit-button").trigger("reset")
         $('.messages').fadeTo( "slow", 1 ).fadeTo(3000, 0);
        }
      });
    });

您应该添加在")};“

Answer 2

我的朋友，分号有微小的错误……

$(document).ready(function() {
$("#submit-button").on('click', function(e) {
e.preventDefault(); // Prevent form submission

// you would need to set the following values from your form fields
var name = $("#form_name").val();
var email = $("#form_email").val();
var phone = $("#form_phone").val();
var message = $("#form_message").val();
var dataString = 'surname='+ name + '&email=' + email + '&phone=' + phone + '&message=' + message;

$.ajax({
  type: "POST",
  url: "contact.php",
  data: dataString,
  success: function() {
    $(".messages").html("Thank you for contacting me.  I will be in touch soon.").css("visibility", "visible");
    $("#submit-button").trigger("reset")
    $('.messages').fadeTo( "slow", 1 ).fadeTo(3000, 0);
  }
});

})；

见trigger("reset");后的第二行

请在jquery后面直接添加BS4 js，这是很好的实践，它可能会导致意外的错误.
