禁用引导程序中的链接

If what you're trying to do is disable an a link, there is no option to do this. I think you can find an answer that will work for you in this question here.

One option here is to use

<a href="/" onclick="return false;">123n</a>

Disabled href tag

You cant set links to "disabled" just system elements like input, textfield etc.

But you can disable links with jQuery/JavaScript

$('.disabled').click(function(e){
e.preventDefault();
});

Just wrap the above code in whatever event you want to disable the links.

I think you need the btn class.
It would be like this:

<a class="btn disabled" href="#">Disabled link</a>

It seems that Bootstrap doesn't support disabled links. Instead of trying to add a Bootstrap class, you could add a class by your own and add some styling to it, just like this:

a.disabled {
/* Make the disabled links grayish*/
color: gray;
/* And disable the pointer events */
pointer-events: none;
}

<!-- Make the disabled links unfocusable as well -->
<a href="#" class="disabled" tabindex="-1">Link to disable</a><br/>
<a href="#">Non-disabled Link</a>

I just created my own version using CSS. As I need to disabled, then when document is ready use jQuery to make active. So that way a user cannot click on a button until after the document is ready. So i can substitute with AJAX instead. The way I came up with, was to add a class to the anchor tag itself and remove the class when document is ready. Could re-purpose this for your needs.

CSS:

a.disabled{
pointer-events: none;
cursor: default;
}

HTML:

<a class="btn btn-info disabled">Link Text</a>

JS:

$(function(){
$('a.disabled').on('click',function(event){
event.preventDefault();
}).removeClass('disabled');
});

I just removed 'href' attribute from that anchor tag which I want to disable

$('#idOfAnchorTag').removeAttr('href');


$('#idOfAnchorTag').attr('class', $('#idOfAnchorTag').attr('class')+ ' disabled');

Thanks for @jacob-van-lingen's comment, You can extend .btn-link in your global style

a.disabled{
@extend .btn-link
}

I developed the following solution because when I apply class styles such as btn disabled offered by Bootstrap 5 to an <a> element inside a card, margin and padding are applied to the element:

.disabled {
color: currentColor;
cursor: not-allowed;
opacity: 0.5;
text-decoration: none;
}

<a href="#" class="disabled">Disabled Link</a>

I liked the answer by Sercan and I added a tiny jQuery to it, so that the links are also not followed on click:

    $(document)
.on("click",
"a.disabled",
function () {
return false;
});

and for the look from the Answer above:

.disabled {
color: currentColor;
cursor: not-allowed;
opacity: 0.5;
text-decoration: none;
}
