Question

我试图通过selenium找出视频进度的价值。我知道我需要找到一种使用java脚本执行器的方法，但还没有发现如何。

这是元素：

<div aria-label="scrub bar" aria-level="polite" 
     aria-valuemax="100" aria-valuemin="0" class="scrubBar" 
     role="slider" tabindex="0" aria-valuenow="100%" aria-valuetext="100%%">

    <vg-scrub-bar-current-time _ngcontent-c27="">
       <div class="background" style="width: 100%;"></div><!---->
    </vg-scrub-bar-current-time>
    <vg-scrub-bar-buffering-time _ngcontent-c27="">
       <div class="background" style="width: 100%;"></div>
    </vg-scrub-bar-buffering-time>      
 </div>

valuenow =＆＃34; 100％是我想要监控的（我想知道它何时达到100％以触发另一个动作）。

任何帮助都将受到高度赞赏。

Answer 1

我不知道如何使用JavaScriptExecutor找到它，既不是Java专家。话虽如此，根据信息，我将等待下面显示的那个元素，一旦发现突然出现并启动另一个动作

这不是您正在寻找的答案，但是可能会或可能不会帮助您提出解决方案

转换为Java语法

 while True:
        percentage = driver.find_element_by_css_selector('div[aria-label="scrub bar"]').get_attribute('aria-valuenow')
        if percentage == '100%':
            break

    ELSE
        BEGIN
            SELECT null;
            RETURN;
        END

        print 'I am here'

    INSERT INTO @temp_T_Html_Word_Categories(Id) SELECT Id FROM T_Html_Word_Categories WHERE FK_KatSubkat_ID = @KatSubkatId And FK_Word_ID = @WordId

    --DECLARE @v XML = (SELECT * FROM @temp_T_Html_Word_Categories FOR XML AUTO)

    Declare @Id int;
    --it makes no difference what you SELECT in an EXISTS sub-query as it is just syntactical sugar. (ie Nothing is actually selected.) SELECT * or SELECT 1 ...
    WHILE EXISTS(SELECT * FROM @temp_T_Html_Word_Categories)        
    BEGIN
        Select Top 1 @Id = Id From @temp_T_Html_Word_Categories;

    INSERT INTO @temp_T_Html_WordCat_Phrase(FK_Phrase_ID) SELECT FK_Phrase_ID FROM T_Html_WordCat_Phrase WHERE FK_Word_Categorie_ID = @Id;
        Delete @temp_T_Html_Word_Categories Where Id = @Id;     
    END;

    --IF EXISTS (SELECT * FROM T_Html_Phrase WHERE Id NOT IN (SELECT FK_Phrase_ID FROM @temp_T_Html_WordCat_Phrase))
    --  SET @IddD = 1;
    --ELSE
    --  SET @IddD = 0;


    SELECT * FROM T_Html_Phrase WHERE Id NOT IN (SELECT FK_Phrase_ID FROM @temp_T_Html_WordCat_Phrase)

    --DECLARE @b XML = (SELECT * FROM T_Html_Phrase FOR XML AUTO)

    Delete @temp_T_Html_WordCat_Phrase;

Answer 2

JavaScript代码：

String value = (String) js.executeScript("return document.getElementByXpath(\"//*[@id=\"cdk- accordion-child-15\"]/div/app-sensors-video/app-cognata-video/vg- player/vg-scrub-bar/div).getAttribute(\"aria-valuenow\")");

为您提供aria-valuenow的值。

更新：

Java代码：

// elem is WebElement
elem.findElement(By.xpath("//*[@id='cdk- accordion-child-15']/div/app-sensors-video/app-cognata-video/vg- player/vg-scrub-bar/div"));

String s = (String) elem.getAttribute("aria-valuenow");
