无法使用Selenium获取WebElement标记名称

Question

I have a popup page that I need to click a button on. The popup page is in Angular.

The button I need to click is:

<button _ngcontent-c8="" class="btn btn-primary" type="button">Apply</button>

The path the method calls take to click the button is as follows:

TemplatePopupPage templatePopupPage = editTemplatePage.clickApplyToClientsButton();
pause(5000);
editTemplatePage = templatePopupPage.clickApplyButton(EditTemplatePage.class);

@SuppressWarnings("unchecked")
public <W> W clickClientSearchApplyButton(Class<W> expectedPage) throws Exception {
    click(clientsApplyButton);
    pause(2000);

    return (W) expectedPage.getConstructors()[0].newInstance();
}

protected void click(WebElement element) {
    String tagName = element.getTagName();
    String attributeType = element.getAttribute("type");
    if (tagName.equals("input")
            && (attributeType.equals("submit"))) {
        element.submit();
        return;
    }
    element.click();
}

public interface WebElement {
   void click();
}

I've tried a couple xpaths which all point to the button successfully, such as:

@FindBy(xpath = "//div[@class='modal-footer']/button[text()='Apply']")
protected WebElement clientsApplyButton;

It keeps failing at the line - String tagName = element.getTagName(); in the click() method. The error message is java.lang.NullPointerException

I don't think it's an issue with the XPath as when I inspect the page, the XPath finds the element on page. And now other element exists with that xpath.

I have a feeling it has something to with the _ngcontent-c8 attribute, because I am able to click buttons on other pages using that same click() method

也许您可以尝试一下： @FindBy(xpath = "//div[@class='modal-footer']/button[con]") protected WebElement clientsApplyButton;
