angular - 元素状态无效 : Element must be user-editable in order to clear it error trying to click and insert a date on a dropdown-toggle using Selenium

Question

我尝试单击此日历并使用 selenium 自动插入日期，但出现以下错误:

invalid element state: Element must be user-editable in order to clear it.

HTML 片段

<a id="enddate-dropdown" class="dropdown-toggle" role="button" data-toggle="dropdown" data-target="">
                <p class="custom-datepickers__date-prefix ng-binding">To:</p>
                <!-- ngIf: displayEndDate -->
                <!-- ngIf: !displayEndDate --><div ng-if="!displayEndDate" class="custom-datepickers__no-date ng-scope"></div><!-- end ngIf: !displayEndDate -->
</a>

代码片段

myclass.SetDateByXpath("//*[@id=\"enddate-dropdown\"]/p", myclass.GetDate("yyyy/MM/dd", mydate));

public void SetDateByXpath(String element, String value)
    {
        WebElement webElement = ExplicitWaitOnElement(By.xpath(element));       
        ((JavascriptExecutor) driver).executeScript(
                "arguments[0].removeAttribute('readonly','readonly')",webElement);
        webElement.clear();
        webElement.sendKeys(value);
    }

如果我手动设置日期，这是 HTML:

<a id="enddate-dropdown" class="dropdown-toggle" role="button" data-toggle="dropdown" data-target="">
                <p class="custom-datepickers__date-prefix ng-binding">To:</p>
                <!-- ngIf: displayEndDate --><p ng-if="displayEndDate" class="ng-binding ng-scope">2019/11/21</p><!-- end ngIf: displayEndDate -->
                <!-- ngIf: !displayEndDate -->
</a>

可能是网站变了，但现在我不知道如何设置这个值。任何帮助将不胜感激。

谢谢

我猜你的错误是在以下几行抛出的:

webElement.clear();
webElement.sendKeys(value)

我们可以尝试通过 Javascript 设置值来解决这个问题:

// updated selector for webElement to grab the p element which contains the date string
WebElement webElement = driver.findElement(By.xpath("//*[@id=\"enddate-dropdown\"]/p[@ng-if='displayEndDate']"));

// try setting inner HTML which is the text inside the p
((JavascriptExecutor) driver).executeScript("arguments[0].innerHtml = '" + value + "';", webElement)

// alternative option is to try setting value instead
// ((JavascriptExecutor) driver).executeScript("arguments[0].value = '" + value + "';", webElement)
