Question

我正在尝试建立一个href URL链接，其中包含一些javascript变量和用于交易电子邮件的静态文本。但是，我无法获取链接或显示的URL来显示为完整的内置URL。

我尝试将它们用单引号和其他一些变体包装，但是URL和显示的URL不会正确显示。谁能解决这个问题？

var folder = "orders";
var orderNumber = "589";
var refNum = "Mon";
var job = "image";

HTML

<p style="margin: 0;">If that button will not work, copy and paste the following link in your browser:</p>
<p style="margin: 0;"><a href='"https://example.com/ + folder + "/" + orderNumber + "-" + refNum + "-" + job + ".jpg"' target="_blank">'"https://example.com/" + folder + "/" + orderNumber + "-" + refNum + "-" + job + ".jpg"'</a></p>

Answer 1

您遇到了问题

href='"https://example.com/ + folder +
                           |___________  Here you should have `"`

您可以直接使用Template literals

var folder = "orders";
var orderNumber = "589";
var refNum = "Mon";
var job = "image";

let link = `<p style="margin: 0;"><a href='"https://example.com/${folder}/${orderNumber}-${refNum}-${job}.jpg' target="_blank">https://example.com/${folder}/${orderNumber}-${refNum}-${job}.jpg</a></p>`

document.querySelector('#link').innerHTML = link

console.log(link)

<div id='link'></div>

Answer 2

最好的解决方案是使用template literal创建端点，然后使用另一个创建HTML。然后，您不必担心所有报价及其顺序：

var folder = "orders";
var orderNumber = "589";
var refNum = "Mon";
var job = "image";

const endpoint = `https://example.com/${folder}/${orderNumber}-${refNum}-${job}.jpg`;
const href = `<a href="${endpoint}" target="_blank">${endpoint}</a>`;

document.querySelector('.link').insertAdjacentHTML('beforeend', href);

<p style="margin: 0;">If that button will not work, copy and paste the following link in your browser:</p>
<p class="link" style="margin: 0;"></p>

Answer 3

您可以尝试以下方法：

<p style="margin: 0;">
   <a id="myLink" href='' target="_blank">""</a>
</p>

 <script type="text/javascript">
     var folder = "orders";
     var orderNumber = "589";
     var refNum = "Mon";
     var job = "image";

     var myLink = document.getElementById("myLink");
     myLink.href = "https://example.com/" + folder 
              + "/" + orderNumber + "-" + refNum + "-" + job + ".jpg";

     myLink.innerHTML = myLink.href;
 <script>

如果您希望模板简洁而通用，则可以使用模板化。否则，您可以尝试使用旧的JS好方法。
