java无法定位元素：{“方法”：“xpath”，“选择器”：“/*[@id='content column']

2 周，1 日 Questions & Answers 4272

以下代码给出了一个错误，即使xpath是正确的：

Unable to locate element: {"method":"xpath","selector":"//*[@id='content column']...

我假设这个领域有多个XPath。这是代码

driver.get("https://marswebtdc.tdc.vzwcorp.com/cdl/lte/fdr_llc/fdr.jsp?3gOr4g=4g");
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

try {
    int i = 5;
    String strI = Integer.toString(i);

    WebElement element = driver.findElement(By.xpath("//*[@id='content column']/table[1]/tbody/tr/td/form/b/table/tbody/tr/td/table/tbody/tr[2]/td[4]/input"));
    JavascriptExecutor executor = (JavascriptExecutor)driver;
    executor.executeScript("arguments[0].click();", element);
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    driver.findElement(By.xpath("//*[@id='content column']/table[1]/tbody/tr/td/form/b/table/tbody/tr/td/table/tbody/tr[2]/td[4]/input")).sendKeys(strI);

    Thread.sleep(3000);
    }
catch(Exception e){
    System.out.println("Elemnt Not Found : "+e.getMessage());
}

不要使用XPath，尤其是你的XPath。难以理解、阅读、维护等。阅读css selectors .如果我正确理解了需要查找的元素，您可以尝试下一个选择器：
```
driver.findElement(By.Css("input#3gOr4g")); 
```
或者像这样的smth=）

如果要查找“MDN:textfield”（如前面的评论所述），请尝试以下XPath：

1-//input[@name='txtMsid']

这将定位name属性为“txtMsid”的输入元素。

2-//td[contains(text(),'MDN')]/following-sibling::td[1]/input

这将在td元素下定位输入元素，该元素是'td'元素的第一个同级元素，它包含作为'MDN'的innerHTML/text

有 Java 编程相关的问题?
