selenium 下拉框无法定位的问题 【很急】

hellen_jia

大家好，我是selenium的新手，现在遇到一个关于如何定位下拉菜单的问题。

具体html 如下：
<select class="form-control ng-pristine ng-untouched ng-valid" ng-model="gus.curr_gu">
    <option value="? object:null ?"></option>
    <option class="ng-binding ng-scope" ng-repeat="gu in gus.gus | orderBy:'guname'" value="Shanghai">Shanghai</option>
    <option class="ng-binding ng-scope" ng-repeat="gu in gus.gus | orderBy:'guname'" value="Beijing">Beijing</option>
</select>

我用了CssSelector的定位方法, 麻烦大家帮忙看看这个有什么问题啊，怎么样可以正常定位到这个元素呢，非常感谢！
SelectElement SelectGU = new SelectElement(driver.FindElement(By.CssSelector("select.form-control.ng-pristine.ng-untouched.ng-valid")));
SelectGU.SelectByValue("Shanghai");

一直报错，下面是exception detail:
OpenQA.Selenium.NoSuchElementException was unhandled
  HResult=-2146233088

你这个css的value写的对么？select.form-control.ng-pristine.ng-untouched.ng-valid，用这个吧SelectElement SelectGU = new SelectElement(driver.FindElement(By.CssSelector("select[class='form-control ng-pristine ng-untouched ng-valid']")));

你先要写点击这个下拉菜单的操作，已经操作了点开菜单后，然后写以下：
        List<WebElement> allOptions = driver.findElements(By.xpath("//select[@class=form-control ng-pristine ng-untouched ng-valid"));
        String targetText="XX";//这里是你下拉选项的text值
        for (int i = 0;i<allOptions.size();i++) {
            if(allOptions.get(i).getText().equals(targetText)){
                allOptions.get(i).click();
            }
        }
