Question

有没有办法使用像ctrl+f之类的东西来搜索网页上的文字？如何使用Java和Selenium搜索和突出显示网页上的某些单词？例如，我需要搜索单词＆＃34; test＆＃34;在此网页上：https://www.wedoqa.com/blog/ 我试着混合一些答案，所以我写了这样的代码：

WebElement matchedElement = driver.findElement(By.xpath("//*[text()='test']"));
            ((JavascriptExecutor) driver).executeScript("arguments[0].setAttribute('style', 'background: yellow; border: 2px solid red;');", matchedElement);
            if(driver.getPageSource().contains(matchedElement.toString())) {
                System.out.println("The page contains word: " + matchedElement.toString());
            } else {
                System.out.println("The page does not contains word asdfghjkl");
            }

但是，我得到了这样的错误：

Answer 1

您可以使用JavaScript Executor突出显示匹配的元素。

样品：

//Partial Match of the word
WebElement matchedElement=driver.findElement(By.xpath("//*[contains(text(),'test')]"));
         (or)
//Exact Match of the word
WebElement matchedElement=driver.findElement(By.xpath("//*[text()='test']"));

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].setAttribute('style', 'background: yellow; border: 2px solid red;');", matchedElement);

Answer 2

You can verify it through page source:

if(driver.getPageSource().contains("test")){
    System.out.println("The page contains word test");
    }
