Twitter Bootstrap's buttons have a nice Loading...
state available.
The thing is that it just shows a message like Loading...
passed through the data-loading-text
attribute like this:
<button type="button" class="btn btn-primary start" id="btnStartUploads"
data-loading-text="@Localization.Uploading">
<i class="icon-upload icon-large"></i>
<span>@Localization.StartUpload</span>
</button>
Looking at Font Awesome, you see that there's now an animated spinner icon.
I tried to integrate that spinner icon when firing an Upload
operation like this:
$("#btnStartUploads").button('loading');
$("#btnStartUploads i").removeAttr('class');
$("#btnStartUploads i").addClass('icon-spinner icon-spin icon-large');
but this had no effect at all, that is, I just see the Uploading...
text on the button.
Is it possible to add an icon when the button is in the Loading state? Looks like somehow Bootstrap just removes the icon <i class="icon-upload icon-large"></i>
inside the button while in the Loading state.
Here's a simple demo that shows the behavior I describe above. As you see when it enters the Loading state the icon just disappears. It reappears right after the time interval.
