Question

在这个html代码中，现金被选为默认值，我想将无线电值更改为卡片。

<label>
    <input id="cash" type="radio" checked="" value="CS" name="cash_cash">
    <i></i>CASH
</label>
<label>
    <input id="card" type="radio" value="CD" name="cash_cash">
    <i></i>Card
</label>

我使用了以下代码，但没有一个给我结果。

方法1

WebElement pl=driver.findElement(By.xpath("//input[@name='cash_cash'and @value='card']"));
pl.click();

方法2

List<WebElement> radiobuttons = driver.findElements(By.id("card"));
for(WebElement radio:radiobuttons)
{
    String cvalue = radio.getAttribute("value");
    if(cvalue .equals("CD"))
    {
        radio.click();
    }
    else
    {
        System.out.println("fails");
    }
}

int rcount = radiobuttons.size();

上面的行给我rcount为4，尽管只有两个选项。

请帮助我（这是一个弹出窗口）。 HTML source

Answer 1

方法1中的XPath表达式不正确。它应该是@id='card'而不是@value='card'。请参阅以下代码：

解决方案1 ：By.xpath

List<WebElement> radiobuttons = driver.findElements(By.xpath("//input[@name='cash_cash'and @id='card']"));
for(WebElement radio:radiobuttons)
{
    if(radio.isDisplayed()){
        radio.click();
        break;
    }   
}

解决方案2 ：By.cssSelector

List<WebElement> radiobuttons = driver.findElements(By.cssSelector("input#card[value='CD']"));
for(WebElement radio:radiobuttons)
{
    if(radio.isDisplayed()){
        radio.click();
        break;
    }
}
