Question

我有一个变量列表，用于检查要返回的条件为true还是false。这在打印到console.log时有效，但现在我需要在玉石模板中渲染它。我收到以下错误。我哪里错了？

Cannot read property 'success' of undefined

玉

  #firstlast #{info.success}

JS

  var fInitialUnderscoreLastName = fInitial + '_' + lastName + email;
  verifier.verify(fInitialUnderscoreLastName, function( err, info ){
    if( err ) console.log(err);
    else{
      var result = info.success;
      console.log( "Info: " + info.info );
    }
  });

  var firstNameUnderscoreLInitial = firstName + '_' + lInitial + email;
  verifier.verify(firstNameUnderscoreLInitial, function( err, info ){
    if( err ) console.log(err);
    else{
      var result = info.success;
      console.log( "Info: " + info.info );
    }
  });

  res.render('index', {
    fInitialUnderscoreLastName: result
    firstNameUnderscoreLInitial: result

  });

您必须像这样呈现视图

res.render('yourView',  {
  "info": {"success": info.success, "info" : info.info},
  "variable2": "value",
  "variable3" : "value"
});

被修改

var fInitialUnderscoreLastName = fInitial + '_' + lastName + email;
var firstNameUnderscoreLInitial = firstName + '_' + lInitial + email;
verifier.verify(fInitialUnderscoreLastName, function( err, info ){
    if( err ) console.log(err);
    else{
      var resultA= info.success;
      verifier.verify(firstNameUnderscoreLInitial, function( err, info ){
        if( err ) console.log(err);
        else{
          var resultB = info.success;
          console.log( "Info: " + info.info );
          res.render('index', {
          "resultA": resultA,
          "resultB": resultB
          });
       }
    });
    }
  });
