这是我的方法:
driver.FindElement(By.XPath("(.//*[normalize-space(text()) and normalize-space(.)='Country:'])[1]/following::span[2]")).SendKeys("USA");
这是它在 html 中的样子:
This how its look in html :
<div _ngcontent-c4="" class="col-xs-8 no-padding-sides ng-star-inserted" style="">
<kendo-dropdownlist _ngcontent-c4="" class="custom-dropdown k-widget k-dropdown k-header ng-pristine ng-invalid ng-touched" formcontrolname="countryId" dir="ltr">
<span role="listbox" unselectable="on" class="k-dropdown-wrap k-state-default" id="k-d0697a91-baeb-4960-bfc1-c023903c1159" dir="ltr" readonly="false" tabindex="0" aria-disabled="false" aria-readonly="false" aria-haspopup="true" aria-expanded="false" aria-owns="dbfc0894-a4f5-4f1b-881f-1d88ccdc6002" aria-activedescendant="f65cbfa2-6280-4a84-908b-ba11da75d59d-undefined">
<span unselectable="on" class="k-input">
<!----><!---->Select Country ...
</span>
<span unselectable="on" class="k-select"><span class="k-i-arrow-s k-icon"></span></span><!---->
</span>
<!----><!---->
</kendo-dropdownlist>
</div>
这是 XPath:
xpath=(.//*[normalize-space(text()) and normalize-space(.)='Country:'])[1]/following::span[2]
如果我想使用 selenium IDE 单击它，下拉列表值的外观是这样的，因为该值是从数据库中检索的:
This how dropdownlist value look like if i want to click on it using selenium IDE because this value is retrieved from database :
- 首先我点击下拉列表
- 第二次选择国家
是否有另一种方法可以在 selenium 中通过键盘而不是发送键来添加值?
Is there another way to add value by keyboard in selenium instead of send key ?
推荐答案
根据您共享的 HTML，目标元素是 <span> 标记，因此您将无法调用SendKeys() 方法.相反，您需要诱导 WebDriverWait 以使所需元素可点击，并且您可以使用以下任一解决方案:
As per the HTML you have shared the target element is a <span> tag so you won't be able to invoke SendKeys() method. Instead you need to induce WebDriverWait for the desired element to be clickable and you can use either of the following solution:
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementToBeClickable(By.XPath("//span[@class='k-dropdown-wrap k-state-default' and @role='listbox']/span[@class='k-input']"))).Click();
//or
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementToBeClickable(By.XPath("//span[@class='k-dropdown-wrap k-state-default' and @role='listbox']//span[@class='k-select']"))).Click();
