我无法创建过滤器来提取我需要的所有元素 [英] I can't create filter to extract all elements that i need

问题描述

即使我不需要价格，我也能得到价格，如何过滤呢?

I get prices, even that I don't need, how can I filter them?

<div class="ssl-price-box">
    <price value="377" units="/yr" class="lg-price ng-isolate-scope"><span class="price"><span class="currency-icon">$</span><span class="integer ng-binding">3.</span><span class="cent ng-binding">77</span><span class="units">/yr</span></span></price>
<!-- ngIf: product.prices.max.certIsPromo -->
</div>   

 <price value="13888" units="/yr" class="lg-price ng-isolate-scope">
        <span class="price">
            <span class="currency-icon">$</span>
            <span class="integer ng-binding">138.</span>
            <span class="cent ng-binding">88</span>
            <span class="units">/yr</span>
        </span>
    </price>

<price ng-if="product.prices.max.certIsPromo" value="21589" units="/yr" old-price="" class="base-price ng-scope ng-isolate-scope">
    <span class="price old-price">
        <span class="currency-icon">$</span>
        <span class="integer ng-binding">215.</span>
        <span class="cent ng-binding">89</span>
        <span class="units">/yr</span>
        <span class="line-through"></span>
    </span>
</price>

我不知道该怎么做.我尝试过

I have no idea how to do it. I tried

const allSSLList = element.all(by.css('div.ssl-price-box')).all(by.className("span[class='price']"));

还有这个

const allSSLList = element.all(by.css('div.ssl-price-box > price'));
expect(await allSSLList)).toBe(newPrices)

我拥有所有元素，但不需要第二个CSS中的class class ="price old-price"中的旧价格，因为我需要将Array与所有新价格进行比较

I got all elements, but I don't need old price in tag class="price old-price" from second css, because I need compare Array with all new prices

预期['377'，'1288'，'2699'，'1688'，'3199'，'1966'，'3588'，'3088'，'4499'，'3888'，'9599'，' 5999"，"6888"，"13899"，"7088"，"9699"，"7819"，"7819"，"13499"，"13888"，"21589"]为"newPrice".

Expected [ '377', '1288', '2699', '1688', '3199', '1966', '3588', '3088', '4499', '3888', '9599', '5999', '6888', '13899', '7088', '9699', '7819', '7819', '13499', '13888', '21589' ] to be 'newPrice'.

推荐答案

使用提供的HTML，您似乎可以使用XPath

With the HTML provided, it looks like you can use the XPath

//div[@class='ssl-price-box']/price[not(@old-price)]
^ find a DIV that has the right class
                             ^ find a child PRICE tag
                                   ^ that does not contain the attribute "old-price"

仅获得不是旧价格的价格.从那里，您可以使用 .getAttribute() 来从每个元素中将value属性拉为"377"，"1288"等.

to only get the price that aren't old prices. From there, you can use .getAttribute() to pull the value attribute from each element as "377", "1288", etc.
