Hi,
I need help to add custom validation to the account textbox inside dialog editor to see if the account exist in the database through API. I tried below code but i can't seem to get it to work.
{ columnKey: "customerAcctNo", editorType: 'text', required: true, editorOptions: { validatorOptions: { custom: { method: function (value, fieldOps) { me._sharedService.validateAccount(value) .subscribe(data => { if (data) {return true;} else {return false;}}) }, errorMessage: "Account doesn't exist" } }, width: "100%" } },
SERVICE:
public validateAccount(account: string): Observable<IUser[]> { let params: URLSearchParams = new URLSearchParams(); if (account) { params.set('customerAcctNo', account); }
let requestOptions = new RequestOptions(); requestOptions.withCredentials = true; requestOptions.search = params;
return this._http.get(this._accountUrl, requestOptions) .map((response: Response) => { if (response) { return true; } else { return false } }) .do(data => console.log('account: ' + JSON.stringify(data))) .catch(this.handleError); }
