Nightwatch.js方法`.element（）`返回“ [object Object]”

Question

I am attempting to retrieve an element from a webpage using the Nightwatch .element() method:

browser.element('class name', 'story-share-tools', function (res) {  
  console.log(res);
});

The res parameter is being displayed in the console as [object Object] and doesn't appear to be a WebElement JSON object .

I need the actual HTML element story-share-tools that contains an unordered list with items I want to iterate over.

It is a bit surprising because I do not have this problem with .element() : object details are displayed in my terminal. I assume you have an issue with .toString() somewhere. As you may know, in JavaScript, [object Object] is the string returned by Object.prototype.toString() .

 var obj = { foo: 'Foo', bar: 'Bar' }; console.log(obj.toString()); 

So instead of doing this:

console.log(res);

Try this:

for (var prop in res) {
  if (res.hasOwnProperty(prop)) {
    console.log(prop, res[prop]);
  }
}
