硒驱动器-从下拉列表中选择所需的锂项目

Question

I am new & trying to learn selenium I am able to select a specific element from the list as I know the xpath:

driver.findElement(By.xpath("*[@id='category-dropdown']/descendant::*[@title='Events']"))

Can anyone please tell me how can I select any item from the list as each item will have a different title name? I just want to select an item by passing the title name as a variable eg select "Jobs" or "Cars & bikes"

I tried the below code but i am getting the list element size as 0

List<WebElement> element=driver.findElements(By.xpath(.//*[@id='category-dropdown']/ul/li));
System.out.println(element.size());
for (WebElement webElement : element)
{       
    System.out.println(webElement.getText());
}

the element size is zero

<div id="category-dropdown" class="drop-layers cate-layer" style="display: block;" data-type="overlay" data-action="focus" data-area="query">
    <ul>
        <li>
            <a href="javascript:void(0);" data-sc_cid="1" data-sc_gid="0" data-sc_cn="all" data-sc_dn="All Categories" title="All Categories">   All Categories </a>
        </li>
        <li>
            <a href="javascript:void(0);" data-sc_cid="1397" data-sc_gid="60" data-sc_cn="cars-bikes" data-sc_dn="Cars & Bikes" title="Cars & Bikes">   Cars & Bikes </a>

Answer 1

Looking at your locator for the list

List<WebElement> element=driver.findElements(By.xpath(.//*[@id='category-dropdown']/ul/li));

You've not enclosed the xpath in quotations, so it won't recognise it as valid, it should be

List<WebElement> element=driver.findElements(By.xpath("//*[@id='category-dropdown']/ul/li"));

Answer 2

Whenever locate an element "" is required.

For example:

driver.findElements(By.id("xyz"));
driver.findElements(By.className("xyz"));
driver.findElements(By.xpath("//*[@id='xyz']"));

simply change this statement

List<WebElement> element=driver.findElements(By.xpath("//*[@id='category-dropdown']/ul/li"));

rest is fine

Answer 3

You can use XPath for that. When you do not have to click on the dropdown first;

WebElement el = driver.findElement(By.xpath("//div[@id = 'category-dropdown']/descendant::li[text() = 'Cars @ Bikes']"));
el.click();

When you have to click the dropdown first:

WebElement dropdown = driver.findElement(By.id("category-dropdown"));
dropdown.click();
dropdown.findElement(By.cssSelector("li[value='Cars & Bikes']")).click();
