javascript - How to mock $(element).show and ko.mapping.fromJS in jasmine test case? -

here code:

testviewmodel.prototype.edit = function(pid, pdata) { self.modalid = '#header'; $(self.modalid).modal('show'); //error self.id(ko.mapping.fromjs(pdata).id()); //how mock ? }

this jasmine test case:

it("calling edit method", function() { var modalid = $("#cc-accesscontrolusermodal"); var editdata = {id:"i10060"}; spyon($.fn, 'modal'); self.testviewmodel.edit("i10060",editdata); });

however, give me:

error: modal() method not exist

so, question is: how mock $(element).show , ko.mapping.fromjs in jasmine test case?
