Slide 21

Slide 21 text

‹#› @tpryan Code Changes Change frontend PUT requests to POST to deal with CORS issues. DB UI API

Slide 22

Slide 22 text

‹#› @tpryan Original UI var url = this.protocol + this.host + this.uri_location_list; var type = "POST"; if (location.id != 0){ url += location.id; type = "PUT"; } $.ajax({ url: url, type: type, data: location, success: successHandler, error: errorHandler }); UI

Slide 23

Slide 23 text

‹#› @tpryan But secretly the API didn’t really care. if ($post_vars['id'] == 0){ // INSERT SQL.. } else { // UPDATE SQL... } API

Slide 24

Slide 24 text

‹#› @tpryan So now this var url = this.protocol + this.host + this.uri_location_list; var type = "POST"; if (location.id != 0){ url += location.id; type = "PUT"; } $.ajax({ url: url, type: type, data: location, success: successHandler, error: errorHandler }); UI var url = this.protocol + this.host + this.uri_location_list; var type = "POST"; if (location.id != 0){ url += location.id; type = "PUT"; } $.ajax({ url: url, type: type, data: location, success: successHandler, error: errorHandler });
