Object with data for the route. As of 1.4+ you can specify a dynamic url property and the url will be parsed and replaced with actual data. $('#form').w2form({ name : 'form', url : '/api/project/:id/details', routeData: { id: 14 }, fields: [ { name: 'first_name', type: 'text', required: true }, { name: 'last_name', type: 'text', required: true }, { name: 'email', type: 'email' } ], record: { first_name : 'John', last_name : 'Doe', email : 'jdoe@email.com' }, actions: { "save": function () { this.validate(); }, "reset": function () { this.clear(); } } }); In the example above, the ":id" from the route will be replaced with "14" from routeData object.
