如何使用 NightmareJS 3.0.1 select Option 标签中的 innerText 和值

How do I select both innerText and value from an Option tag using NightmareJS 3.0.1

我正在处理一些事情,发现我可以很容易地连接两个返回的数组,但它不是很干......你会如何处理这个????我需要选项文本和值,因为它们是不同的东西,但需要将它们返回到同一个对象中,以便我可以处理返回的所述值......最好是如果我能以某种方式映射减少它,那么函数 returns 一个 key/value 对象会更好,但我不确定这是否可能:

//define a new Nightmare method named "textExtract"
//note that it takes a selector as a parameter
Nightmare.action('textExtract', function(selector, done) {
    //`this` is the Nightmare instance
    this.evaluate_now((selector) => {
      //query the document for all elements that match `selector`
      //note that `document.querySelectorAll` returns a DOM list, not an array
      //as such, convert the result to an Array with `Array.from`
      //return the array result
      text =  Array.from(document.querySelectorAll(selector))
        //extract and return the text for each element matched
        .map((element) => element.text );
      elValues =  Array.from(document.querySelectorAll(selector))
        //extract and return the text for each element matched
        .map((element) => element.value );
        return text.concat(elValues)
    //pass done as the first argument, other arguments following
    }, done, selector)
  });

referenced from github.

这个怎么样:

Nightmare.action('textExtract', function(selector, done) {
  this.evaluate_now((selector) => {
    return Array.from(document.querySelectorAll(selector))
      .map(o => ({value: o.value, text: o.text}))
  }, done, selector)
})

结果类似于:

[
  { text: 'Bob', value: '766' },
  { text: 'Renee', value: '768' },
  { text: 'Paul', value: '787' }
]
