aurelia-http-client

I think your answer is very useful to me. post.html <template> <section> <form role="form" submit.trigger="signup()"> <div class="form-group"> <label for="OrganisationId">OrganisationId</label> <input type="text" value.bind="organisationId" placeholder="OrganisationId"> </div> <div > <label for="OrganisationName">OrganisationName</label> <input type="OrganisationName" value.bind="organisationName" placeholder="Password"> </div> <button type="submit"
