视频模态引导程序

Question

我有一个问题，已经在几个朋友的网页上工作了几天，我需要用YouTube的视频做模态，我正在使用swig，因为在我看来，编译到html是非常有效的，当你使用对象作为JSON时，一个大衣，问题是我已经设法使用图像制作模态，非常简单，但是视频更复杂。

这是我的css：

  #headerLogo{
    background: url(https://images2.alphacoders.com/698/698137.jpg);
    background-size: cover;
    height: 250px;
    display: block;
    margin-top: 50px;
  }
  #text{
    color: white;
    position: absolute;
    text-align:center;
    font-size: 36px;
    width: 100%;
    padding: 0;
    margin: 0;
    line-height: 250px;
  }
  .navbar{
    margin-bottom: 0px;
  }
  .fa{
    font-size:22px;
    color: #0077cd;
  }
  .fa:hover{
    color: #0890f2;
  }
  .footer{
    text-align: center;
    color: #c6c6c6;
  }
  #indexImage{
    width:100%;
    height: auto;
  }
  #myImg {
    border-radius: 5px;
    cursor: pointer;
    transition: 0.3s;
}

#myImg:hover {opacity: 0.7;}

/* The Modal (background) */
.modal {
    display: none;
    position: fixed;
    z-index: 1;
    padding-top: 100px;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    overflow: auto;
}

.modal-content {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
}

/* Caption of Modal Image (Image Text) - Same Width as the Image */
#caption {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
    text-align: center;
    color: #000000;
    padding: 10px 0;
    height: 150px;
}

/* Add Animation - Zoom in the Modal */
.modal-content, #caption {
    -webkit-animation-name: zoom;
    -webkit-animation-duration: 0.6s;
    animation-name: zoom;
    animation-duration: 0.6s;
}

@-webkit-keyframes zoom {
    from {-webkit-transform:scale(0)}
    to {-webkit-transform:scale(1)}
}

@keyframes zoom {
    from {transform:scale(0)}
    to {transform:scale(1)}
}

/* The Close Button */
.close {
    top: 15px;
    right: 35px;
    color: #ffffff;
    font-size: 60px;
    font-weight: bold;
    transition: 0.3s;
}

.close:hover,
.close:focus {
    color: #bbb;
    text-decoration: none;
    cursor: pointer;
}

/* 100% Image Width on Smaller Screens */
@media only screen and (max-width: 700px){
    .modal-content {
        width: 100%;
    }
}

这是我的js文件：

// Get the modal
var modal = document.getElementById('myModal');
var images = document.getElementsByClassName("imageClass");
for(var i = 0; i < images.length; i++){
    var img = images[i];
    var modalImg = document.getElementById("img01");
    var captionText = document.getElementById("caption");
    img.onclick = function(){
        modal.style.display = "block";
        modalImg.src = this.src;
        modalImg.alt = this.alt;
        captionText.innerHTML = this.alt;
    }
}
var span = document.getElementsByClassName("close")[0];

// When the user clicks on <span> (x), close the modal
$('#closeImage').onclick = function() {
  modal.style.display = "none";
}

这是我的projects.html用swig编写的：

{% extends 'layout.html' %}

{% block title %}{{ title }}{% endblock %}
{% block header %}{% include 'header.html' %}{% endblock %}
{% block headerLogo %}{% include 'headerLogo.html' %}{% endblock %}
{% block styles %}{% include 'styles.html' %}{% endblock %}
{% block content %}

  <div>
    {% for key, val in projectImages %}
      {% if val.type == "image" %}
        <img id="myImg" class="imageClass" src="{{val.src}}" alt="{{val.title}}" width="300" height="200">
      {% elseif val.type == "video" %}
        <img id="myImg" class="videoClass" src="http://img.youtube.com/vi/{{val.src}}/0.jpg" alt="{{val.title}}" width="300" height="200">
      {% endif %}
    {% endfor %}
    <div id="myModal" class="modal">
      <span id="closeImage" class="close" onclick="document.getElementById('myModal').style.display='none'">&times;</span>
      <img class="modal-content" id="img01">
      <div id="caption"></div>
    </div>
  </div>
  <script src="../js/fotoInModal.js"></script>
{% endblock %}

我的JSON对象：

{
  "title": "Argochamber",
  "indexContent":"Was created in 2012, by Pablo Blanco Celdrán and Eric Dacal Sanchez, in order to create fun games and for the whole world.",
  "navButtons" : [{"name": "Projects", "src": "./projects.html"}, {"name": "Contacts", "src": "./contacts.html"},{"name": "Teams", "src":"./teams.html"}],
  "imageUrl" : "https://avatars0.githubusercontent.com/u/17063359?v=4&s=200",
  "imageHeaderLogo" : "https://images2.alphacoders.com/698/698137.jpg",
  "headerNavBar": "navbar-light bg-primary",
  "fontawesome": [{"icon": "fa fa-facebook-official", "src": "https://www.facebook.com/argochamber/?ref=br_rs"},
  {"icon": "fa fa-twitter-square", "src": "https://twitter.com/argochamber"}],
  "projectImages":[{"title": "Spiderman in New York", "src": "../image/spidey.jpg", "type": "image"},
  {"title": "Sculpting link", "src":"ALbt17LLH54", "type": "video"}],
  "css": {
    "headerTextColor": "white",
    "headerFontSize": "36px"
  }
}

在projects.html img，您有iframe而不是YouTube {% elseif val.type == "video" %} <img id="myImg" class="videoClass" src="http://img.youtube.com/vi/{{val.src}}/0.jpg" alt="{{val.title}}" width="300" height="200"> {% endif %}
