网页调用文件另存为js

查看引用是否正常，页面添加html代码。

<a id="downLoad" onclick="oDownLoad('downLoad')">下载</a>
    <input type="hidden" name="fgycompany.fileUrl" value="地址" />

　　

<script>

    </script>

　　第二种方法

var save_link = document.createElementNS("http://www.w3.org/1999/xhtml", "a");
            //地址
            save_link.href = "/fonts/glyphicons-halflings-regular.svg";
            save_link.download = name;
            var ev = document.createEvent("MouseEvents");
            ev.initMouseEvent(
                "click", true, false, window, 0, 0, 0, 0, 0
                , false, false, false, false, 0, null
            );
            save_link.dispatchEvent(ev);
