I want to check if a disabled attribute is not present on a button using NightwatchJS.

I tried doing these:

• .assert.attributeContains('.phone-verify-btn', 'disabled', 'null')

• .assert.attributeContains('.phone-verify-btn', 'disabled', null)

• .assert.attributeContains('.phone-verify-btn', 'disabled', 'false')

• .assert.attributeContains('.phone-verify-btn', 'disabled', false)

But these don't seem to work like they do to check if disabled is set to true like so:

• .assert.attributeContains('.phone-verify-btn', 'disabled', 'true')

This works just fine! Any idea what's happening here? The error I get is rather cryptic:

Element does not have a disabled attribute. - expected "null" but got: null

• javascript
• node.js
• selenium
• nightwatch.js

• I have the exact same problem. What I'm currently doing is .assert.elementNotPresent('.phone-verify-btn[disabled]'), but I also would like a cleaner solution. – Adam Zerner Commented Aug 6, 2018 at 0:14

In this case,I think you should get attribute first until we have better solution. This one works for me :

 Browser.getAttribute('@element','disabled',function(result){
   if(result.value === 'true'){
      // element is disabled , do what you want
   }
   // element not disabled .
  })

Perhaps it is not really logical !

Change attributeContains to attributeEquals

.assert.attributeEquals('.phone-verify-btn', 'disabled', null)
