Add glyphicon to JS code?

Question

I am trying to add glyphicon in JS file used for showing error message. Is that possible and if it is how can I do that?

Here is the current code:

if (freeSpotFound == false) { 
    raiseError("Error!", "#add-item-error");
    return;
}

Is it possible to add glyphicon before the "Error!"text?

Answer 1

It depends on what raiseError() does
Try adding some HTML, and see if it works

if (freeSpotFound == false) { 
    raiseError("<span class=\"glyphicon glyphicon-exclamation-sign\" aria-hidden=\"true\"></span> Error!", "#add-item-error");
    return;
}
