How to clear a <label>'s text

Try

$('label[id*="singleModelText"]').text('');

Or if .text('') doesn't work

$('label[id*=singleModelText]').html('');

but if there's an id why not just do this:

$('#singleModelText').html('');

Try with

   $('label[id*=singleModelText]').empty();

OR

   $('label[id*=singleModelText]').text('');
