Python:Selenium chromedriver不适用于button cli

Question

我希望使用selenium python单击按钮，但错误，下面是我单击按钮的python代码：

br.find_element_by_css_selector("span[id^='rallybutton-1121-btnIconEl']").click()

或者

^{pr2}$

或者

br.find_element_by_xpath('//*[@id="rallybutton-1121"]').click()

等等也不可行

下面是我的检查元素：

<a class="x4-btn secondary rly-small x4-unselectable x4-btn-default-small x4-icon x4-btn-icon x4-btn-default-small-icon" style="float:right;border-width:0;" hidefocus="on" unselectable="on" tabindex="0" id="rallybutton-1121" role="button">
   <span id="rallybutton-1121-btnWrap" role="presentation" class="x4-btn-wrap" unselectable="on"><span id="rallybutton-1121-btnEl" class="x4-btn-button" role="presentation">

     <span id="rallybutton-1121-btnInnerEl" class="x4-btn-inner x4-btn-inner-center" unselectable="on">&nbsp;</span>

        <span role="presentation" id="rallybutton-1121-btnIconEl" class="x4-btn-icon-el icon-export " unselectable="on" style="">&nbsp;</span>
     </span>
   </span>
</a>

我的按钮是这样的：

我想点击导出到CSV。。。在

错误：

Answer 1

您在代码中使用的IDrallybutton-1121看起来非常动态。在

您可以使用如下css选择器从ID中提取rallybutton：

a[id^='rallybutton']  

代码应该是：

^{pr2}$

建议：检查dev tool中的a[id^='rallybutton']，确保只有一个条目。在

考虑在代码中添加WebDriverWait，以获得更高的稳定性。在

希望这有帮助。在
