I assume you know how to get the DOM object for the <a>
element (use document.getElementById
or some other method).
我假设您知道如何获取<a>
元素的 DOM 对象(使用document.getElementById
或其他方法)。
To add any attribute, just use the setAttributemethod on the DOM object:
要添加任何属性,只需在 DOM 对象上使用setAttribute方法:
a = document.getElementById(...);
a.setAttribute("href", "somelink url");

First, try changing <a>Link</a>
to <span id=test><a>Link</a></span>
.
首先,尝试更改<a>Link</a>
为<span id=test><a>Link</a></span>
.
Then, add something like this in the javascript function that you're calling:
然后,在您调用的 javascript 函数中添加如下内容:
var abc = 'somelink';
document.getElementById('test').innerHTML = '<a href="' + abc + '">Link</a>';
This way the link will look like this:
这样,链接将如下所示:
<a href="somelink">Link</a>

document.getElementById('link-id').href = "new-href";
I know this is an old post, but here's a one-liner that might be more suitable for some folks.
