启动本地PageAbility

PageAbility相关的能力通过featureAbility提供，启动本地Ability通过featureAbility中的startAbility接口实现。

表1 featureAbility接口说明

接口名	接口描述
startAbility(parameter: StartAbilityParameter)	启动Ability。
startAbilityForResult(parameter: StartAbilityParameter)	启动Ability，并在该Ability被销毁时返回执行结果。

如下示例通过startAbility显式启动PageAbility。启动Ability的参数包含want，关于want的说明详见对象间信息传递载体Want，相应的，隐式启动与显式启动也不在此赘述。

import featureAbility from '@ohos.ability.featureAbility'
(async () => {
  try {
    console.info('Begin to start ability')
    let param = {
      want: {
        bundleName: "com.example.myapplication",
        moduleName: "entry",
        abilityName: "com.example.myapplication.EntryAbility"
      }
    }
    await featureAbility.startAbility(param)
    console.info(`Start ability succeed`)
  } 
  catch (error) {
    console.error('Start ability failed with ' + error)
  }
})()
