如何确定与另一个Web元素的链接是可单击的

Question

我正在开展一个项目。我必须确定链接是否可点击。这是链接：

<div id="divMegamenu" class="column span_10_of_16 center_text mega_menu">
<a href="#" class="close_popup menu"></a>
    <nav class="desktop_mega">
        <ul>
            <li id="g_women">
                <span class="global_cat"><a href="http://www.forever21.com/Product/Category.aspx?br=f21&amp;category=app-main">women</a></span>

以下是我写的xpath：

 WebElement imgElement = driver.findElement(By.xpath("//nav[@id = 'desktop_mega']/ul/li[@id='g_women']/span[@id='global_cat']/a"));

但它继续提出没有这样的元素的例外

Answer 1

desktop_mega和global_cat是类，而不是ID。将nav[@id = 'desktop_mega']替换为nav[@class='desktop_mega']，将span[@id='global_cat']替换为span[@class='global_cat']

WebElement imgElement = driver.findElement(By.xpath("//nav[@class='desktop_mega']/ul/li[@id='g_women']/span[@class='global_cat']/a"));
