Question

我需要通过Selenium webdriver上传文件。但如果我使用类似的东西：

driver.findElement(By.xpath("//input[@type='file']")).sendKeys(file.getAbsolutePath());

然后我发现了一个错误：

org.openqa.selenium.ElementNotVisibleException: Element is not currently visible and so may not be interacted with
Command duration or timeout: 128 milliseconds
Build info: version: '3.0.1', revision: '1969d75', time: '2016-10-18 09:49:13 -0700'
System info: os.name: 'Windows 7', os.arch: 'x86', os.version: '6.1', java.version: '1.8.0_91'
Driver info: org.openqa.selenium.firefox.FirefoxDriver

所以我想我需要使用js删除Hidden属性，我找到了这段代码：

JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("document.getElementsByTagName('*')[0].removeAttribute('hidden');");

但它不适合我。

这是我正在处理的代码：

<label name="file" ng-model="file" ngf-accept="pattern" ngf-pattern="pattern" ngf-select="uploadSubmit($file)" ng-disabled="isUploadDisabled()" type="button" class="button button--large ng-pristine ng-untouched ng-valid ng-empty">
                <span translate="" class="button__text">Загрузить из файла .xls</span>
                <input type="file" hidden="" ng-disabled="isUploadDisabled()">
            </label>

Answer 1

这应该有效：

试一试：

console.log(document.getElementsByTagName("input")[0].removeAttribute('hidden'));

或

if (document.all !== undefined) { var allElements = document.all; } else { var allElements = document.getElementsByTagName("*"); } allElements[0].removeAttribute('hidden');

我建议不要使用JS方法通过代码删除function imagecreatefromfile( $filename ) { if (!file_exists($filename)) { throw new InvalidArgumentException('File "'.$filename.'" not found.'); } switch ( strtolower( pathinfo( $filename, PATHINFO_EXTENSION ))) { case 'jpeg': case 'jpg': return imagecreatefromjpeg($filename); break; case 'png': return imagecreatefrompng($filename); break; default: throw new InvalidArgumentException('File "'.$filename.'" is not valid jpg or png.'); break; } } /* do resizing of picture */ $src = imagecreatefromfile($target); $path1 = strtolower( pathinfo( $target, PATHINFO_EXTENSION )); list ($width, $height) = getimagesize($target); $newwidth = 300; if($heigth > $width){ $newheight = ($height/$width)*$newwidth; } else if($width == $height){ $newheight = 300; } else if($width > $height){ $newheight = ($width/$height)*$newwidth; } unlink($target); switch ($path1) { case 'jpg': $tmp = imagecreatetruecolor($newwidth, $newheight); imagecopyresampled($tmp, $src, 0, 0, 0, 0, $newwidth, $newheight, $width, $height); imagejpeg($tmp, $target, 90); imagedestroy($src); imagedestroy($tmp); break; case 'png': $backgroundImg = imagecreatetruecolor($width, $height); $color = imagecolorallocate($backgroundImg, 255, 255, 255); imagefill($backgroundImg, 0, 0, $color); imagecopy($backgroundImg, $src, 0, 0, 0, 0, $width, $height); $tmp2 = imagecreatetruecolor($newwidth, $newheight); imagecopyresampled($tmp2, $backgroundImg, 0, 0, 0, 0, $newwidth, $newheight, $width, $height); imagejpeg($tmp2, $target, 90); imagedestroy($src); imagedestroy($backgroundImg); imagedestroy($tmp2); break; } ?>属性，因为Selenium将用于模拟实际的用户操作。

就像用户点击任何按钮并且网站显示hidden一样。我建议你先触发相同的组件，然后在显示后使用隐藏的组件。

首先尝试添加一些等待时间，以便可以在DOM中加载元素。否则，请尝试使用以下代码使元素可见。

WebElement element = yourWebDriverInstance.findElement(Locator);

((JavascriptExecutor) yourWebDriverInstance).executeScript(arguments[0].style.height='auto'; arguments[0].style.visibility='visible';, element);
