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';
import Want from '@ohos.app.ability.Want';
import hilog from '@ohos.hilog';const TAG: string = 'PagePageAbilityFirst';
const domain: number = 0xFF00;

(async (): Promise<void> => {try {hilog.info(domain, TAG, 'Begin to start ability');let want: Want = {bundleName: 'com.samples.famodelabilitydevelop',moduleName: 'entry',abilityName: 'com.samples.famodelabilitydevelop.PageAbilitySingleton'};await featureAbility.startAbility({ want: want });hilog.info(domain, TAG, `Start ability succeed`);}catch (error) {hilog.error(domain, TAG, 'Start ability failed with ' + error);}
})()
