javascript - res.render不显示数据

Question

我有一个函数可以以不同的格式构建电子邮件地址并检查其有效性。一切都在服务器端运行，但是我很难在 Jade 模板中显示结果。一切看起来都是正确的，所以我不确定出了什么问题..

Jade

  #firstLast !{resultA}
  #firstDotLast !{resultB}
  #fInitialLastName !{resultC}
  #fInitialDotLastName !{resultD}
  #firstNameLInitial !{resultE}
  #firstNameDotLInitial !{resultF}
  #firstNameOnly !{resultG}
  #lastNameOnly !{resultH}
  #firstNameUnderscoreLastName !{resultI}
  #fInitialUnderscoreLastName !{resultJ}
  #firstNameUnderscoreLInitial !{resultK}

Express(提前对这个嵌套的噩梦表示抱歉。除了底部的 res.render 之外，一切正常)

app.get('/verify', function (req, res) {
  var firstName = req.query.firstName;
  var lastName = req.query.lastName;
  var email = req.query.email;

  var fInitial = firstName.charAt(0);
  var lInitial = lastName.charAt(0);


  var firstLast = firstName + lastName + email;
  var firstDotLast = firstName + '.' + lastName + email;
  var fInitialLastName = fInitial + lastName + email;
  var fInitialDotLastName = fInitial + '.' + lastName + email;
  var firstNameLInitial = firstName + lInitial + email;
  var firstNameDotLInitial = firstName + '.' + lInitial + email;
  var firstNameOnly = firstName + email;
  var lastNameOnly = lastName + email;
  var firstNameUnderscoreLastName = firstName + '_' + lastName + email;
  var fInitialUnderscoreLastName = fInitial + '_' + lastName + email;
  var firstNameUnderscoreLInitial = firstName + '_' + lInitial + email;

  //console.log(fInitial + ' ' + lInitial)

  //console.log(firstLast);

  verifier.verify(firstLast, function( err, info ){
    if( err ) console.log(err);
    else{
      var resultA = firstLast + ':' + ' ' + info.success;
      console.log( "Info: " + info.info );

      verifier.verify(firstDotLast, function( err, info ){

                                              console.log( "Info: " + info.info );

                                              return res.render('index', {
                                              "resultA": resultA,
                                              "resultB": resultB,
                                              "resultC": resultC,
                                              "resultD": resultD,
                                              "resultE": resultE,
                                              "resultF": resultF,
                                              "resultG": resultG,
                                              "resultH": resultH,
                                              "resultI": resultI,
                                              "resultJ": resultJ,
                                              "resultK": resultK
                                           });
                                          }
                                        });
                                        }
                                      });
                                    }
                                  });
                                }
                              });
                            }
                          });
                        }
                      });
                    }
                  });
                }
              });
            }
          });
        }
      });
    }
  });
});

客户端 JS

$('#verify').click(function() {
  var parameters = {
    firstName: $('#firstName').val(),
    lastName: $('#lastName').val(),
    email: $('#email').val() };
  $.get('/verify', parameters, function(data) {
    console.log('hey' + parameters);
  });
});

预期的行为是每个电子邮件地址将返回 true 或 false 并在每个相应的 div 中显示结果

Answer 1

问题出在客户端的 GET 请求中，我还没有写完。从那里我意识到我使用的是 res.render 而不是 res.send ，它返回整个模板而不是我需要的对象。

完成并工作的代码:

$('#verify').click(function() {
  var parameters = {
    firstName: $('#firstName').val(),
    lastName: $('#lastName').val(),
    email: $('#email').val() };
  $.get('/verify', parameters, function(data) {
    console.log(data.resultA); //Returns full body of HTML
    $('#firstLast').html(data.resultA);
    $('#firstDotLast').html(data.resultB);
    $('#fInitialLastName').html(data.resultC);
    $('#fInitialDotLastName').html(data.resultD);
    $('#firstNameLInitial').html(data.resultE);
    $('#firstNameDotLInitial').html(data.resultF);
    $('#firstNameOnly').html(data.resultG);
    $('#lastNameOnly').html(data.resultH);
    $('#firstNameUnderscoreLastName').html(data.resultI);
    $('#fInitialUnderscoreLastName').html(data.resultJ);
    $('#firstNameUnderscoreLInitial').html(data.resultK);
  });
});
