如何在CI中使用javascript

我想编写这个CI视图的代码，如何编写js并在CI中调用它？代码如下：

<script type="text/javascript" src="<?php base_url() ?>/assets/js/jquery.js"></script>
    <script type="text/javascript" src="<?php base_url() ?>/assets/js/qrcodelib.js"></script>
    <script type="text/javascript" src="<?php base_url() ?>/assets/js/webcodecamjquery.js"></script>

    <script type="text/javascript">
        var arg = {
            resultFunction: function(result) {
                $('#as').append($("<input hidden='text' name='code' id='road' value='" + result.code + "'><br><label>QR Code Berhasil Discan, Silahkan Klik Allow / Berbagi data lokasi</label><br>"));
                var x = document.getElementById("ar");
                if (navigator.geolocation) {
                    navigator.geolocation.watchPosition(showPosition);
                  } else { 
                    x.innerHTML = "Geolocation is not supported by this browser.";
                  }
                  function showPosition(position) {
                    x.innerHTML="<input hidden='text' name='lat' value='" + position.coords.latitude + 
                    "'><input hidden='text' name='long' value='" + position.coords.longitude + "'><label>Lokasi Telah didapatkan, silahkan Klik Submit</label>";
                }
            }
        };
        $("canvas").WebCodeCamJQuery(arg).data().plugin_WebCodeCamJQuery.play();            
    </script>

您可以创建自定义js文件，将js代码添加到该文件中。并在CI视图中包含新的js文件

 <script type="text/javascript" src="<?php base_url() ?>/assets/js/jquery.js"></script>
 <script type="text/javascript" src="<?php base_url() ?>/assets/js/qrcodelib.js"></script>
 <script type="text/javascript" src="<?php base_url() ?>/assets/js/webcodecamjquery.js"></script>
 <script type="text/javascript" src="<?php base_url() ?>/assets/js/custJs.js"></script>
