Question

<input type="text" id="mobile" name="mobile" placeholder="Mobile Number" maxlength="10" value="" onkeyup="javascript:dispLocMob(this);" onkeydown="javascript:dispLocMob(this);" onchange="javascript:dispLocMob(this);">

上面显示的是我正在尝试发送密钥的元素。我尝试过xpath和id以及各种选择器，但它会抛出一个错误，如下所示：

Unable to locate element: {"method":"xpath","selector":"/html/body/div[3]/div/form/div[2]/div[1]/input"}

Web元素中是否有定义的内容不允许我访问Selenium脚本中的元素？任何建议/意见将受到高度赞赏。谢谢你！

Answer 1

尝试如下： -

WebDriverWait wait = new WebDriverWait(driver, 10);
el = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("mobile")));
el.sendKeys("your value");

注意： - 在finding element之前确保它不在frame或iframe内。如果它位于任何frame或iframe内，您需要先将frame切换为： - driver.switchTo().frame("frame name or id")

希望它会帮助你...... :)

Answer 2

首先，如果您使用的是xpath，则使用相对xpath而不是绝对值，因为DOM中的轻微更改会使绝对xpath无效或引用错误的元素。

第二次尝试使用.click（）;在.sendkeys（）;之前。所以你的代码可以是

WebElement ele = dvr.findElement(By.id("mobile"));
ele.click();
ele.sendKeys("your string");

最后，请确保您在页面上没有任何具有相同属性的重复元素，即id ==＆＃34; mobile＆＃34;。希望这有帮助

Answer 3

请尝试以下代码：

如果元素不在任何框架中：

driver.findElement(By.id("mobile")).sendKeys("");
如果元素在框架内：

// Switching to the frame

driver.switchTo().frame(<framename>);

driver.findElement(By.id("mobile")).sendKeys("");

driver.switchTo().defaultContent();

另外，请在启动页面并输入文本后添加一些等待。即使代码不起作用，请使用以下代码检查元素是否可见：

if(driver.findElement(By.id("mobile")).isDisplayed()) {
   // Add the code given above
}

希望这有帮助
