java无法从下拉列表中选择值：ElementNotVisibleException

Question

我正在用Java selenium自动输入用户的数据，但他必须通过下拉菜单选择状态。我收到一个异常错误

我尝试过使用所有选择器：

drpState.selectByIndex(5);
drpState.selectByValue("CA");
drpState.selectByVisibleText("California");

我有以下html代码：

<div class="col-sm-4 form-group">
            <label id="xstateLabel">@lang('messages.state')</label>
            <select class="form-control js-select" style="width: 100%" id="xstate" name="xstate">
                <option value=""> State </option>
                <option value="AL" <?php if(isset($usr->state) && $usr->state=='AL'){echo 'selected';} ?>>Alabama</option>
                <option value="AK" <?php if(isset($usr->state) && $usr->state=='AK'){echo 'selected';} ?>>Alaska</option>
                <option value="AZ" <?php if(isset($usr->state) && $usr->state=='AZ'){echo 'selected';} ?>>Arizona</option>
                <option value="AR" <?php if(isset($usr->state) && $usr->state=='AR'){echo 'selected';} ?>>Arkansas</option>
                <option value="CA" <?php if(isset($usr->state) && $usr->state=='CA'){echo 'selected';} ?>>California</option>
                <option value="CO" <?php if(isset($usr->state) && $usr->state=='CO'){echo 'selected';} ?>>Colorado</option>
                <option value="CT" <?php if(isset($usr->state) && $usr->state=='CT'){echo 'selected';} ?>>Connecticut</option>
                *
                *
                *
          </select>

我创建了这个函数：

public void select() {
    Select drpState = new Select(driver.findElement(By.id("xstate")));

    drpState.selectByValue("CA");
}

但我得到了一个错误：

Answer 1

试试这个

WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("xstate")));

Select drpState = new Select(driver.findElement(By.id("xstate")));

drpState.selectByValue("CA");
