具有淡入淡出效果的按钮有问题

如何解决具有淡入淡出效果的按钮有问题

Sleep（）`可以正常工作，但是如果没有它们，它就无法工作，我尝试了不同的方法，例如可见性，elementtobeclickeable等，但问题是该元素还没有准备好被选中，因为正在淡化关闭。

_wait.Until(SeleniumExtras.WaitHelpers.
    ExpectedConditions.PresenceOfAllElementsLocatedBy(By.XPath("//*[@id=\"DataTables_Table_7_wrapper\"]/div[2]/div[1]/div/table/thead/tr/th[1]/input")));

//Thread.Sleep(1000);
WEValuador.ChkBoxAllRefacciones.Click();
WEValuador.BtnModificar.Click();

_wait.Until(SeleniumExtras.WaitHelpers.
    ExpectedConditions.PresenceOfAllElementsLocatedBy(By.XPath("/html/body/div[5]/a[4]/span")));

//Thread.Sleep(1000);
WEValuador.BtnAutorizacion.Click();

_wait.Until(SeleniumExtras.WaitHelpers.
    ExpectedConditions.PresenceOfAllElementsLocatedBy(By.XPath("/html/body/div[5]/a[1]/span")));

//Thread.Sleep(1000);
WEValuador.BtnAutorizado.Click();

ASU.AssertMsjs();

这是错误：

Message: 
    System.Reflection.TargetInvocationException : Exception has been thrown by the target of an invocation.
      ----> System.InvalidOperationException : unknown error: Element <input class="selected-item-all select-checkbox" data="" type="checkbox" name="" value=""> is not clickable at point (330,490). Other element would receive the click: <div class="modal show" id="SpinnerLoader" tabindex="-1" role="dialog" aria-labelledby="loadMeLabel" data-backdrop="static" data-keyboard="false" style="padding-right: 17px; display: block;">...</div>

解决方法

要对Click()而不是PresenceOfAllElementsLocatedBy()上的任何单个元素，必须为ElementToBeClickable()引入 WebDriverWait ，并且可以使用以下Locator Strategy ：

_wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementToBeClickable(By.XPath("//*[@id=\"DataTables_Table_7_wrapper\"]/div[2]/div[1]/div/table/thead/tr/th[1]/input")));

,

在这种情况下，JavaScript执行器确实可以帮助解决问题。而不是等待ElementToBeClickable和Visible。使用Java脚本

Java-

WebElement element = driver.findElement(By.id("gbqfd"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();",element);

C＃-

IJavascriptExecutor jse = (IJavascriptExecutor) driver; 
jse.executeScript("arguments[0].click()= element ); 

,

   This was my solution,you could to quit thread.sleep();

公共静态IWebElement SafeWaitForDisplayed（IWebElement webElement） {

        var w = new DefaultWait<IWebElement>(webElement);
        w.Timeout = TimeSpan.FromSeconds(30);
        w.IgnoreExceptionTypes(typeof(NoSuchElementException),typeof(StaleElementReferenceException),typeof(System.Reflection.TargetInvocationException));

        return w.Until(ctx =>
        {
            var elem = webElement;
            if (elem.Displayed) {
                Thread.Sleep(500);
                return elem;
            }
            else
                return null;
        });

        //Thread.Sleep(100);
