Indicates the tabindex base value for generated form fields. Setting this value can be useful if you have multiple auto-generated forms on the same page.
The value of .tabindexBase will be added to the "normal" tabindex value of the generated field.
Note that setting the tabindex of a field in the field atribute still has priority over the genrated tabindex value.

In this example, the first field will have a tabindex value of 101: var form = $('#form').w2form({ name : 'form', header : 'Form with modified tabindex base', tabindexBase: 100, fields : [ { field: 'first_name', type: 'text', html: { text: 'First Name',} }, { field: 'zip', type: 'int', html: { text: 'Zip' } }, { field: 'short_bio', type: 'text', html: { text: 'Short Bio' } }, // for talk_name tabindex "502" will be used instead of "104" { field: 'talk_name', type: 'text', html: { text: 'Talk Name', attr:'tabindex=502' } }, { field: 'description', type: 'text', html: { text: 'Talk Description' } } ] });
