将jQuery与Selenium WebDriver一起使用 - 如何将JSON对象转换为WebElement？
[英]Using jQuery with Selenium WebDriver - How to cast JSON Object to WebElement?
问题描述
I'm using Selenium WebDriver and I'd like to execute jQuery code to find some elements. 
我正在使用Selenium WebDriver，我想执行jQuery代码来查找一些元素。
My code is as follows: 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($script, ''); executeScript（$ script，''）; returns a WebElement JSON Object and I need to cast it to WebElement in order for the code to work, so I use typecast($grantsDocsfileInput, 'WebElement'); 返回一个WebElement JSON对象，我需要将它转换为WebElement才能使代码工作，所以我使用了类型转换（$ grantsDocsfileInput，'WebElement'）;
However, it's not casting correctly. 但是，它没有正确投射。
This is the expected var_dump result: 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
}
This is the result I get: 这是我得到的结果：

What am I doing wrong? 我究竟做错了什么？ Is this the correct approach to use jQuery with Selenium WebDriver? 这是在Selenium WebDriver中使用jQuery的正确方法吗？ I can get attribute values but if executeScript finds an Object (eg a Button) it returns a stdClass and I can't convert it to WebElement in order to click the Button, for example. 我可以获取属性值但是如果executeScript找到一个Object（例如一个Button），它将返回一个stdClass，我无法将其转换为WebElement以便单击Button，例如。

What about something like this instead? 相反，这样的事情怎么样？ Wouldn't this be a lot easier? 这会不会容易多了？
WebElement p = (WebElement)((JavascriptExecutor)driver)
.executeScript("return document.documentElement;");
In PHP, that would be: 在PHP中，那将是：
$element = (WebElement)$this->webdriver->executeScript("return document.documentElement;");

我想你只需要在你的jquery语句中调用“get（）”
return $('#itemlist .grant_file_upload:first').get();
