Question

我创建了一个如下所示的JSP页面：

每个文件都有其自己的唯一URL链接，我可以单独复制它们而不会出现任何问题。但是，我添加了复选框，以便用户可以勾选所需的文件，然后单击Copy Selected URL。

例如，如果用户选中了两个链接并将其粘贴在记事本上，则它应类似于：

LINK1

LINK2

这是我的JSP页面，显示您可以看到的屏幕截图：

<table class="filesTbl">
    <tr>
        <th width="1%">
            Checkbox
        </th>
        <th width="1%">
             No
        </th>
        <th width="20%">
            File Name
        </th>
        <th width="50%">
            Unique URL
        </th>
        <th width="1%">
            Edit
        </th>
        <th width="1%">
            Copy
        </th>
        <th width="1%">
            Email
        </th>

    </tr>

<%
    //need to input logic to populate data on each row

    int counter=0;

    String[] split = request.getParameter("nodeID").split(",",0);
    for(int i=0;i<split.length;i++){

        long file=Long.parseLong(split[i]);

        List files = fileFacade.list_items(file);
        for (Iterator rstltr = files.iterator(); rstltr.hasNext();) {
            Fmedia fv = (Fmedia) rstltr.next();
            Node nd = nodeFacade.get(fv.getNodeid(), false);
            // Fmedia fm = fileFacade.get_file(fv.getNodeid());

            int count = 0;
            count++;
            long fileid= nd.getNodeid();

            el.value = copyText;
            el.setAttribute('readonly', '');
            el.style = {
                position: 'absolute',
                left: '-9999px'
            };
            document.body.appendChild(el);
            el.select();
            document.execCommand('copy');
            document.body.removeChild(el);
            alert("You have copied the URL");
        }
    </script>





</table>




</div>

<!--Copy button to copy multiple links -->

<div class="wrapper">
<input type="button" value="Copy Selected URL">
</div>
<style>


    .wrapper {
        position: absolute;
        top: 90%;
        left: 5%;
    }

</style>

</body>

我相信我添加的复选框必须唯一，才能分别标识每个URL。

我对JavaScript不太熟悉，可以通过编程方式完成吗？

如何使用JavaScript一次复制多个网址？
