Bootstrap MaxLength - Demo

Default usage

The badge will show up by default when the remaining chars are 10 or less:

$('input[maxlength]').maxlength();

Change the threshold value

Do you want the badge to show up when there are 20 chars or less? Use the threshold option:

 $('input.className').maxlength({
 threshold: 20
 });
 

Few options

 $('input.className').maxlength({
 alwaysShow: true,
 threshold: 10,
 warningClass: "label label-success",
 limitReachedClass: "label label-danger"
 });
 

All the options

This is a complete example where all the options configured for the bootstrap-maxlength counter are setted.

Please note: if the alwaysShow option is enabled, the threshold option is ignored.

 $('input.className').maxlength({
 alwaysShow: true,
 threshold: 10,
 warningClass: "label label-success",
 limitReachedClass: "label label-danger",
 separator: ' of ',
 preText: 'You have ',
 postText: ' chars remaining.',
 validate: true
 });
 

What about textareas?

Bootstrap maxlength supports textarea as well as inputs. Even on old IE.

 $('textarea#textarea').maxlength({
 alwaysShow: true
 });
 

Let's play with the position

The field counter can be positioned at the top, bottom, left or right. You can also place the maxlength indicator on the corners: bottom-right, top-right, top-left, bottom-left and centered-right.
All you need to do is specify the placement option, with one of those strings. If none is specified, the positioning will be defauted to 'bottom'.

 $('input#placement').maxlength({
 alwaysShow: true,
 placement: 'top-left'
 });
