jquery - 如何在 scrapy 中使用 selenium 驱动程序单击第二个链接(使用 python)

Question

我想使用 selenium 驱动程序使用 python 单击下面 html 中的第二个链接。但我无法弄清楚如何做到这一点。

<div class="outerResults" style="">
    <div class="results searchResults" style="display: block;">

        <table cellspacing="0" id="resultGroup">
            <colgroup>
            </colgroup>
            <tbody>
                <tr>
                    <td class="selector">
                        <a href="#" id="p_-1454220127" title="Gary Smith" class="checkbox unchecked">&nbsp;</a>
                    </td>
                    <td class="personName">
                        <a href="#!search/profile/person?personId=-1454220127&amp;targetid=profile">
                        Gary Smith
                        </a>
                    </td>
                    <td class="title">
                        Chief Executive Officer and Co-Founder
                        <input type="hidden" name="" value="Chief Executive Officer and Co-Founder" id="personTitle">

                    </td>

                    </td>
                </tr>
                <tr>
                    <td class="selector">

                    </td>
                    <td class="personName">
                        <a href="#!search/profile/person?personId=-1832984054&amp;targetid=profile">

                    <td class="title">

                            </a>
                        </div>
                    </td>
                    <td class="contact">
                        <span class="unmaskContactText">Click to view this profile</span>
                        <span class="detailContactMask">Email</span>
                        <span class="upsellContainer" rel="upsellContactInfo">&nbsp;</span><br>
                        <div class="phoneNumber">
                            <span class="detailContactMask">Phone</span>
                        </div>
                    </td>
                    <td class="date">
                        <span class="date" title="Last Update">
                        6/24/15
                        </span>
                    </td>
                </tr>
            </tbody>
        </table>
    </div>
</div>

目的是点击<td class="personName">的文本，例如 Gary Smith和 Tesla EVs .我试着点击Gary Smith使用下面的代码

WebDriverWait(self.driver,10).until(EC.presence_of_element_located((By.CLASS_NAME, "personName"))).click()

但什么也没发生。而且我也不知道如何使用 selenium 驱动程序来单击 Tesla EVs

我想说的是，随着输入的不同，内容名称会动态变化。所以准确地说，我想单击第一个和第二个链接，而内部内容名称是随机的

任何能给我提示的人都将不胜感激。

Answer 1

要点击 Gary Smith 链接尝试:

WebDriverWait(self.driver,10).until(EC.presence_of_element_located((By.XPATH, "//a[.='Gary Smith']"))).click()

或

WebDriverWait(self.driver,10).until(EC.presence_of_element_located((By.LINK_TEXT, 'Gary Smith'))).click()

同样适用于 Tesla EVs:

WebDriverWait(self.driver,10).until(EC.presence_of_element_located((By.XPATH, "//a[.='Tesla EVs']"))).click()

或

WebDriverWait(self.driver,10).until(EC.presence_of_element_located((By.LINK_TEXT, "Tesla EVs"))).click()

如果链接文本不固定，请尝试使用以下选择器:

# For 'Gary Smith'
WebDriverWait(self.driver,10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "tr:nth-child(1) > td.personName > a"))).click() 
# For 'Tesla EVs'
WebDriverWait(self.driver,10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "tr:nth-child(2) > td.personName > a"))).click()
