ui tab select using variable

I am having problems when trying to change a tab

The code below is working

$('#tabs').tabs('select', 开发者_JS百科1);

WORKING FINE

The code below

var nextTab=$('#nextTab').val();
$('#tabs').tabs('select', nextTab);

IS NOT WORKING

The nextTab variable is a valid tab index

What am I missing?

Are you sure nextTab holds a valid tab index? If yes, don't know if this makes a difference, but try converting it to a Number:

var nextTab = Number($('#nextTab').val());
