NightwatchJS kann nicht innerhalb eines Abschnitts getvalue

Question

Ich habe den folgenden Befehl in einem Abschnitt eingebettet:

verify: function (input) { 
    this 
     .waitForElementVisible('@value'); 
    this 
     .getValue('.keystone-body form .field-type-text[for="name"] input[name="name"]', function(result) { 
      this.assert.equal(result.value, input.value); 
     }); 
    this 
     .getValue('.keystone-body form .field-type-text[for="name"]', function(result) { 
      console.log('***result: ' + JSON.stringify(result)); 
     }); 
    this 
     .getValue('@value', function (result) { 
      console.log('***result: ' + JSON.stringify(result)); 
     }); 
    return this; 
}, 

Wie Sie in den Selen-Protokolle, alle vier Funktionsaufrufe beziehen sich auf den gleichen Wähler Baum (der dritte man sehen kann, ist, eigentlich eine Repräsentation des Selektorbaums, der die Ausnahme auf dem 4. passieren lässt). Die ersten drei funktionieren gut. Das vierte jedoch nicht und generiert die Ausnahme in den Protokollen unten. Beachten Sie, dass ich in der dritten Version denselben Selektor verwendet habe, der die Ausnahme verursacht und funktioniert. Ich habe auf die Seite gegangen, wo dies die folgende Abfrage (das gleiche wie die 3. und 4. Abfragen oben) passiert und funktioniert auch:

document.querySelector('.keystone-body form .field-type-text[for="name"]') 

Nachtschwärmer-Protokolle:

Ich habe Runden auf diesem einen gegangen und kann nicht an der Ursache ankommen. Alle Hinweise würden sehr geschätzt werden!

Answer 1

Es stellt sich heraus, dass die Seite eine sehr eingebettete kleine Form hatte, die irgendwie den generierten Sektionsselektor abwarf.
