javascript - 如何使用 if 与 $http.post 的数据回调？

Question

我试图让我的应用程序运行到我的 if 语句中，但它进入了 else 语句，这不是我想要的。回调数据是“通过”，这对于我的 if 条件是正确的，但它仍然运行到 else 。请看一下我的代码。

js文件

$http.post(path, postdata
                ).success(function (data, status, headers, config) {
                    //if (data) {

                       // $scope.PostDataResponse = data;
                       if (data === "Pass"){

                        setCookie("Username", $scope.formdata.Username);
                        setCookie("cafe_id", $scope.formdata.cafe_id);
                        console.log(getCookie("Username"));

                        alert("ลงทำเบียนสำเร็จ !");   
                        $location.url('/viewSaveCafeDetail');
                        //console.log(data);
                        //alert("สมัครสมาชิกสำเร็จ");


                        //$scope.insertcafe();
                        //$scope.sendEmail();
                        //  $scope.reset();
                        //  $scope.getData();




                        }else{ <--- ran down to else statement
                            alert(data); <--- callback value is "Pass" which is match with my if condition.
                        }

Answer 1

您的 PHP 文件有 echo "Pass ";，其中写入“Pass”，后跟一个空格，您将与不带空格的字符串“Pass”进行比较。

此外，您的 PHP 文件末尾可能还有一个空行，该空行也将包含在输出中。可以通过删除末尾的 ?> 标签来解决此问题。
