Protractor - 通过 count() 遍历所有元素 function 对我不起作用

Question

I want to iterate through elements by:

let newsCards = element.all(by.css('.design-article--without-image.design-article.design-tile'));

  for(let card = 0; card <= newsCards.count(); card++) {} 

and it doesn't work for me.

It doesn't call any error, my test passes but don't do what it should. I solve it by simple number iteration, but I would be happy to know why there is an issue to iterate with count().

Can somebody help me with this?

Answer 1

newsCards.count() is a Promise. You need to resolve it first to get a number eventually. Normally you do it this way using await keyword

let newsCards = element.all(by.css('.design-article--without-image.design-article.design-tile'));

let count = await newsCards.count()
for(let card = 0; card < count; card++) {}

Keep in mind, that what was said in comments is also right and you should be using < instead of <=
