arguments [0] .click（）不工作在select选项在selenium [英] arguments[0].click() not working for select option in selenium

问题描述

我使用selenium进行网络应用程序自动化。

我停留在一点，我使用 .ExecuteScript（）执行一些操作，像点击一个链接，为此使用： -

I am using selenium for the web application automation.
I stuck in one point,I am using .ExecuteScript() to perform some action like to click on a link and for that am using :-

((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].click()", driver.FindElement(By.XPath("//a[contains(text(),'Login to the Demo')]")));

[注意：对于每个可点击的元素， ，这种方法，因为可点击的元素可能被隐藏或不可见的网页]
但是这种方法不适用于
< select> < option> item< option> ..< / select>


我使用以下代码单击选择选项之一：

[Note : for every click-able element am using ,this approach because click-able element may be hidden or not visible in web page] But this approach is not working for
<select> <option>item<option> .. </select>

I am using below code clicking on one of the select option :

((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].click()", driver.FindElement(By.XPath("//select[@id='form_switcher']/option[5]")));

但没有发生任何错误或异常。


- 编辑开始 -

但如果我使用 ExecuteScript（）然后它的工作很好：

but nothing is happening nor giving any error/exception.

--Edit start--
But if I use without ExecuteScript() then its work fine:

driver.FindElement(By.XPath("//select[@id='form_switcher']/option[5]")).Click();

- 编辑结束 -

< br> [注意：我使用点击选择选项，以便它触发更改事件。]

--Edit end--

[Note : I am using click to select options so that it fire the change event.]

使用（（IJavaScriptExecutor）驱动程序）单击选择选项.ExecuteScript




提前感谢。

So can anyone please explain me how to click on the select option using ((IJavaScriptExecutor)driver).ExecuteScript

Thanks in advance.

推荐答案

对于下拉列表，您需要选择而不是点击。您应该返回元素，然后执行 element.SelectedIndex = 5;

For dropdowns you need to select and not click. You should return the element and then perform a element.SelectedIndex = 5;

如果需要修改javascript要通过javascript而不是selenium获取元素，您可以使用位于 document.evaluate /Web/API/document.evaluate?redirectlocale=en-US&redirectslug=DOM%2Fdocument.evaluaterel =nofollow> https://developer.mozilla.org/en-US/docs/Web/API/document .evaluate？redirectlocale = en-US& redirectslug = DOM％2Fdocument.evaluate

If you need to modify your javascript to get the element via javascript instead of selenium you can utilize the document.evaluate located https://developer.mozilla.org/en-US/docs/Web/API/document.evaluate?redirectlocale=en-US&redirectslug=DOM%2Fdocument.evaluate

，因此您会传回代表select元素的元素， SelectedIndex 值。

so then you return an element that represents your select element and then set the SelectedIndex value.

我相信这是正确的...

I believe this is correct...

((IJavaScriptExecutor)driver).ExecuteScript("var element = document.evaluate(\"//select[@id='form_switcher']\", document.documentElement, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null); element.SelectedIndex = 5;  return element.fireEvent('event specifics go here')");
