将 jQuery 与 Selenium WebDriver 结合使用 - 如何将 JSON 对象转换为 WebEleme

Using jQuery with Selenium WebDriver - How to cast JSON Object to WebElement?

本文关键字：JSON 对象 转换 WebEleme jQuery Selenium WebDriver 结合 | 更新日期: 2023-09-27

我正在使用Selenium WebDriver，我想执行jQuery代码来查找一些元素。

我的代码如下：

public function uploadGrantDoc() {
    $script = "return $('#itemlist .grant_file_upload:first');";
    $grantsDocsfileInput = $this->webdriver->executeScript($script, '');
    $grantsDocsfileInputWebElement = $this->typecast($grantsDocsfileInput, 'WebElement');
    var_dump($grantsDocsfileInputWebElement);
    // Sets the Grants' Docs File Input value
    $grantsDocsfileInputWebElement->sendKeys(array($this->grantsDocsFileDirectory));
    // Submits the Form
    $grantsDocsfileInputWebElement->submit();
    // The success message must be present
    $this->checkIfSuccessMessageIsPresent();
}
function typecast($old_object, $new_classname) {
    if(class_exists($new_classname)) {
      $old_serialized_object = serialize($old_object);
      $new_serialized_object = 'O:' . strlen($new_classname) . ':"' . $new_classname . '":' .
                       substr($old_serialized_object, $old_serialized_object[2] + 7);
      return unserialize($new_serialized_object);
    }
    else
      return false;
}
executeScript（$script， ''

）; 返回一个 WebElement JSON 对象，我需要将其转换为 WebElement 才能使代码正常工作，所以我使用 typecast（$grantsDocsfileInput， 'WebElement'）;

但是，它未正确转换。

这是预期的var_dump结果：

object(WebElement)#15 (2) {
  ["requestURL":protected]=>
  string(83) "http://localhost:4444/wd/hub/session/faadc168-4e8d-4fd5-b777-906885697030/element/6"
  ["_curl":protected]=>
  NULL
}

这是我得到的结果：

  NULL

  NULL

我做错了什么？这是将jQuery与Selenium WebDriver一起使用的正确方法吗？我可以获取属性值，但是如果executeScript找到一个对象（例如按钮），它将返回一个stdClass，例如，我无法将其转换为WebElement以单击按钮。

这样的事情呢？ 这不是容易得多吗？

WebElement p =  (WebElement)((JavascriptExecutor)driver)
   .executeScript("return document.documentElement;");

在 PHP 中，这将是：

$element = (WebElement)$this->webdriver->executeScript("return document.documentElement;");

我认为你只需要在你的jquery语句中调用"get（）"

return $('#itemlist .grant_file_upload:first').get();
