Question

我在codeigniter中尝试了这些代码当这一切都在一起时，这个代码正在运行，但是当我将它们分开时，我创建了一个css文件，还有一个js文件，然后给它们一个链接来加载css和js文件然后这个代码没有运行，如何分离它的js和CSS？

要在codeigniter中加载我的css，我写这段代码

<?= link_tag('style.css'); ?>

要在codeigniter中加载我的js文件，我写这段代码

 <script type="" src="<?= base_url(''); ?>">


<!DOCTYPE html>
<html>
<head>
<style>
#myImg {
    border-radius: 5px;
    cursor: pointer;
    transition: 0.3s;
}

#myImg:hover {opacity: 0.7;}

/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.9); /* Black w/ opacity */
}

/* Modal Content (image) */
.modal-content {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
}

/* Caption of Modal Image */
#caption {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
    text-align: center;
    color: #ccc;
    padding: 10px 0;
    height: 150px;
}

/* Add Animation */
.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 {
    position: absolute;
    top: 15px;
    right: 35px;
    color: #f1f1f1;
    font-size: 40px;
    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%;
    }
}
</style>
</head>
<body>

<h2>Image Modal</h2>
<p>In this example, we use CSS to create a modal (dialog box) that is hidden by default.</p>
<p>We use JavaScript to trigger the modal and to display the current image inside the modal when it is clicked on. Also note that we use the value from the image's "alt" attribute as an image caption text inside the modal.</p>

<img id="myImg" src="<?php echo base_url('assests/img/profile.png');?>" width="300" height="200">

<!-- The Modal -->
<div id="myModal" class="modal">
  <span class="close">×</span>
  <img class="modal-content" id="img01">
  <div id="caption"></div>
</div>

<script>
// Get the modal
var modal = document.getElementById('myModal');

// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img01");
var captionText = document.getElementById("caption");
img.onclick = function(){
    modal.style.display = "block";
    modalImg.src = this.src;
    captionText.innerHTML = this.alt;
}

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

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

</body>
</html>

这可能会对你有所帮助

<!DOCTYPE html> 
<html lang = "en">

   <head> 
      <meta charset = "utf-8"> 
      <title>CodeIgniter View Example</title> 
      <link rel = "stylesheet" type = "text/css" 
         href = "<?php echo base_url(); ?>css/style.css"> 
      <script type = 'text/javascript' src = "<?php echo base_url(); 
         ?>js/sample.js"></script> 
   </head>

   <body> 
      <a href = 'javascript:test()'>Click Here</a> to execute the javascript function. 
   </body>

</html>

尝试将您的DOM相关代码放在某些function中，并在文档正文的function上调用onload，如下所示：

需要放入单独的.js文件的JS代码：

function myJSFunction(){
    // Get the modal
    var modal = document.getElementById('myModal');

    // Get the image and insert it inside the modal - use its "alt" text as a caption
    var img = document.getElementById('myImg');
    var modalImg = document.getElementById("img01");
    var captionText = document.getElementById("caption");
    img.onclick = function(){
        modal.style.display = "block";
        modalImg.src = this.src;
        captionText.innerHTML = this.alt;
    }

    // Get the <span> element that closes the modal
    var span = document.getElementsByClassName("close")[0];

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

修改HTML <body>标记，如下所示：

<body onload="myJSFunction()">
   <h2>Image Modal</h2>
    .
    .

尝试这个

<link rel = "stylesheet" type = "text/css" href = "<?php echo base_url('path/style.css'); ?> "> 
<script type = 'text/javascript' src = "<?php echo base_url('path/sample.js'); 
         ?>"></script>

我试图将这些代码分成单独的文件
