Question

如何使用selectize.js计算下拉列表中的选项数量？

$('#MyDrop option').length;

$('#MyDrop option').size();

以上不适用于选择！

Answer 1

获取所有选择

的选项

let options = $('#selectElem')[0].selectize.options;

获取对象的所有键

let count = Object.keys(options);
console.log(count.length);

Answer 2

使用Selecize API，您可以使用此方法获取选项：

@Before
public void setup(){
    DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.setCapability("noReset","true");
            capabilities.setCapability("fullReset","false");
            capabilities.setCapability("automationName","Appium");
            capabilities.setCapability("platformName", "Android");
            capabilities.setCapability("VERSION", "5.1.1");
            capabilities.setCapability("deviceName", "LG Nexus 5");
            capabilities.setCapability("appPackage", "com.packageName");
            capabilities.setCapability("appActivity", "ui.activity.SplashScreenActivity");
driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
}

@Test
public void sampleTest(){
//Testing Code Only
}

//To Exit/Quit close the driver
    @After
    public void teardown() {
        if (driver != null)
            driver.quit();
    }

然后遍历对象来计算它们：

options = $('#my_select_widget')[0].selectize.options;

计算selectize.js中的选项数量
