Selenium_WebDriver下拉框练习_Java

下拉选择框是常见的WEB页面元素，一般的下拉框tagName为Select，还是以某财BBS为例，它的下拉框源码如下所示，这个下拉框一开始只显示省份选择，选择完之后才会显示属于该省的城市的选择框。

<select id="resideprovince" class="ps" tabindex="1" onchange="showdistrict(‘residecitybox‘, [‘resideprovince‘, ‘residecity‘, ‘residedist‘, ‘residecommunity‘], 4, 1, ‘reside‘)" name="resideprovince">
<option value="">-省份-</option>
<option value="北京市" did="1">北京市</option>
<option value="天津市" did="2">天津市</option>
<option value="河北省" did="3">河北省</option>
<option value="山西省" did="4">山西省</option>
<option value="内蒙古自治区" did="5">内蒙古自治区</option>
<option value="辽宁省" did="6">辽宁省</option>
<option value="吉林省" did="7">吉林省</option>
<option value="黑龙江省" did="8">黑龙江省</option>

一般来说，有两种方式可以操作这种标准的下拉框：

//用普通定位+click方式处理下拉框
 dr.findElement(By.xpath("//select[@id=‘resideprovince‘]/option[@value=‘浙江省‘]")).click();
//等待两秒，让页面刷新，显示出城市下拉框
Thread.sleep(2000);    dr.findElement(By.xpath("//select[@id=‘residecity‘]/option[@value=‘杭州市‘]")).click();

//用Select方式
Select sProvince = new Select(dr.findElement(By.xpath("//select[@id=‘resideprovince‘]")));
sProvince.selectByValue("浙江省");
Thread.sleep(2000);
Select sCity = new Select(dr.findElement(By.xpath("//select[@id=‘residecity‘]")));
        sCity.selectByValue("杭州市");

以下代码实现功能如下：

1. 登录BBS
2. 打开子版块
3. 关闭左侧导航栏并窗口最大化
4. 模拟鼠标移动选择搜索条件
5. 输入关键字搜索
6. 切换窗口到搜索结果页面
7. 操作下拉框搜索同城用户
8. 格式化输出搜索结果
