Unable to perform click action in selenium python
提问by Zeinab Abbasimazar
I'm writing a test script using selenium in python. I have a web-page containing a tree-view object like this:
我正在 python 中使用 selenium 编写测试脚本。我有一个包含树视图对象的网页，如下所示：
I want to traverse over the menu to go to the desired directory. Respective HTML code for plus/minus indications is this:
我想遍历菜单以转到所需的目录。加/减指示的相应 HTML 代码是这样的：
<a onclick="changeTree('tree', 'close.gif', 'open.gif');">
<img id="someid" src="open.gif" />
</a>
The srcattribute of the image can be either open.gifor close.gif.
src图像的属性可以是open.gif或close.gif。
I can detect weather there is a plus or minus by simply checking the srcattribute of the imgtag. I can also easily access to the parent tag, a, by using .find_element_by_xpath("..").
我可以通过简单地检查标签的src属性来检测天气的img好坏。我也可以很容易地访问父标签，a通过使用.find_element_by_xpath("..")。
The problem is that I can't perform the click action not on the imgnor the atag.
问题是，我不能在没有进行点击操作img，也没有a标签。
I'v tried webdriver.Actions(driver).move_to_element(el).click().perform(); but it did not work.
我试过了webdriver.Actions(driver).move_to_element(el).click().perform()；但它没有用。
I think I should mention that there is no problem in accessing the elements, since I can print all their attributes; I just can't perform actions on them. Any help?
我想我应该提到访问元素没有问题，因为我可以打印它们的所有属性；我只是无法对它们执行操作。有什么帮助吗？

Here's the js code for collapsing and expanding the tree:
这是用于折叠和展开树的 js 代码：
function changeTree(tree, image1, image2) {
if (!isTreeviewLocked(tree)) {
var image = document.getElementById("treeViewImage" + tree);
if (image.src.indexOf(image1)!=-1) {
image.src = image2;
} else {
image.src = image1;
}
if (document.getElementById("treeView" + tree).innerHTML == "") {
return true;
} else {
changeMenu("treeView" + tree);
return false;
}
} else {
return false;
}
}

I Googled for some hours and I found out that there is a problem about triggering the Javascript events and the click action from web-driver. Additionally I have a spantag in my web-page that has an onclickevent and I also have this problem on it.
我在谷歌上搜索了几个小时，发现在触发 Javascript 事件和来自网络驱动程序的点击操作方面存在问题。另外span，我的网页中有一个标签，上面有一个onclick事件，我也有这个问题。

After some tries like .execute_script("changeTree();"), .submit(), etc, I have solved the issue by using the ActionChainsclass. Now, I can click in all elements that they have java-script events as onclick. The code that I have used is this:
经过一些尝试，例如.execute_script("changeTree();")，.submit()等，我已经通过使用ActionChains该类解决了该问题。现在，我可以单击所有具有 java 脚本事件的元素作为onclick. 我使用的代码是这样的：
from selenium import webdriver
driver = webdriver.Firefox()
driver.get('someURL')
el = driver.find_element_by_id("someid")
webdriver.ActionChains(driver).move_to_element(el).click(el).perform()
I don't know if it occurred just to me or what, but I found out that I should find the element right before the key command; otherwise the script does not perform the action. I think it would be related to staling elements or something like that; anyway, thanks all for their attention.
我不知道它是否只是发生在我身上或者是什么，但我发现我应该在键盘命令之前找到元素；否则脚本不会执行操作。我认为这与陈旧元素或类似的东西有关；无论如何，感谢大家的关注。
