尝试:

driver.find_element_by_css_selector("a[href='javascript:showQuote('10003')']").click()
driver.find_element_by_xpath("//a[@href="javascript:showQuote('10003')"]").click()
driver.find_element_by_partial_link_text('showQuote('10003')').click()
driver.find_element_by_css_selector('[href^=javascript:showQuote('10003')]').click()
driver.execute_script('showQuote('10003')')

最佳答案

您是否尝试过使用如下所示的 xpath

   //tbody/tr[5]/td[11]/a/img

我知道如果 tr 和 td 继续变化，那么采取 5、11 之类的位置是不合适的。但尝试一次看看是否能够点击。

你可以这样尝试

  //a[starts-with(@href, 'javascript:showQuote') and contains(@href, '10003')]

如果您使用的是 Firefox 浏览器，请使用带有 firepath 插件的 firebug 来检查它是否正在获取所需的唯一元素。
