Nightwatch js how to assert multiple elements

Question

i'm trying to assert/verify multiple elements for an attribute with Nightwatch.js.

I tried to use the "elements" command by selenium but it seems to not actually return a tag.

browser.elements('css selector','icon_checkmark', function (result) {
    this.verify.attributeEquals(result.value, 'aria-hidden', 'true');
})

The console outputs this error:

Testing if attribute aria-hidden of <[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]> equals "true". 
Element could not be located.  - expected "true" but got: null
ERROR: Unable to locate element: "[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]" using: css selector

It seems like it finds the right things because there should be 6 but then somehow I read out the wrong thing? Console.log of result.value[0] gives just { ELEMENT: '19' } which seems correct.

Any idea how could I make this work? I want to check if all elements with the class icon_checkmark have an attribute aria-hidden="true".

https://code.google.com/p/selenium/wiki/JsonWireProtocol#/session/:sessionId/elements – "Returns: {Array.<{ELEMENT:string}>} A list of WebElement JSON objects for the located elements." unfortunately I couldn't figure out how to get the actual element by the "The opaque ID assigned to the element by the server". — e382df99a7950919789725ceeec126, Feb 10 '15 at 06:52
I can't figure it out either but I made it a little further: https://github.com/nightwatchjs/nightwatch/issues/512 — Daniel Coffman, Jun 23 '15 at 20:55

attributeEquals locate element using css selector, while elements returns ID of element, so you can't locate the element that way. You can use elementIdAttribute to get the element and verify it.

browser.elements('css selector','icon_checkmark', function (result) {
  result.value.map(function (v, k) {
    browser.elementIdAttribute(v.ELEMENT, 'aria-hidden', function (res) {
      // true
      return browser.assert.equal(res.value, 'expected value');
    });
  });
})

result.value is an array. so you would need to loop through the array result.value[x]
