Question

我想從硒webdriver的下拉菜單中選擇一個值，但它只是打開下拉菜單並立即關閉它。

這裏是webdriver的代碼：

driver.findElement(By.cssSelector("span.k-select ")).click(); 
     Thread.sleep(3000); 
     driver.findElement(By.xpath("//li[@class='k-item'][.='Revenue per click']")).click(); 

這是從瀏覽器的下拉列表中的html代碼：

<div class="controls"> 
    <span class="k-widget k-dropdown k-header kendo-input span8 ddFix" unselectable="on"> 
     <span unselectable="on" class="k-dropdown-wrap k-state-default"> 
     <span unselectable="on" class="k-input">Select revenue type... 
     </span> 
     <span unselectable="on" class="k-select"> 
      <span unselectable="on" class="k-icon k-i-arrow-s">select</span> 
     </span> 
     </span> 
     <input name="revenueType" id="revenueType" class="kendo-input span8 ddFix" data-role="dropdownlist" style="display: none;"> 
    </span> 
</div> 

<div class="k-animation-container km-popup"> 
     <div class="k-list-container k-popup k-group k-reset" id="revenueType-list" data-role="popup"> 
      <ul unselectable="on" class="k-list k-reset" tabindex="-1" role="listbox" aria-hidden="true" id="revenueType_listbox" aria-live="off" style="overflow: auto;"> 
       <li tabindex="-1" role="option" unselectable="on" class="k-item">Select revenue type...</li> 
       <li tabindex="-1" role="option" unselectable="on" class="k-item">Revenue per action</li> 
       <li tabindex="-1" role="option" unselectable="on" class="k-item">Revenue per click</li> 
       <li tabindex="-1" role="option" unselectable="on" class="k-item">Revenue per sale</li> 
       <li tabindex="-1" role="option" unselectable="on" class="k-item">Revenue per action + Revenue per sale</li> 
       <li tabindex="-1" role="option" unselectable="on" class="k-item">Revenue per mile</li> 
      </ul> 
     </div> 
    </div> 

Answer 1

很難沒有上下文來調試，但：

1. 您的定位器無效，請嘗試使用：

   By.xpath("//li[text()='Revenue per click']") 
   

   由於只有一個項目具有該文本，所以應該足夠了。如果你仍然想在選擇@class，使用

   By.xpath("//li[@class='k-item' and text()='Revenue per click']") 
   

2. 嘗試使用JavaScript改變不可選擇爲關閉使用JavaScript執行。

獲取下拉文本值後進行點擊操作

subdropdown_child = navigationDriver.findElements(By.cssSelector("select#ctl00_SPWebPartManager1_g_c873566a_540c_4681 option");         
for (Element subchild : subdropdown_child) 
    {  
    dropdown_value = subchild.text(); 
    new Select(navigationDriver.findElementByCssSelector("select#ctl00_SPWebPartManager1_g_c873566a_540c_4681_")).selectByVisibleText(dropdown_value); 
    }
