app.vue获取状态栏高度

		<!-- 底部导航 -->
		<!-- <transition name='slide'> -->

		<!-- </transition> -->
	</div>
</template>

<script>

			document.addEventListener("plusready", function() {

				_this.statusBarHeight = Number.isFinite(plus.navigator.getStatusbarHeight()) ? plus.navigator.getStatusbarHeight() : 28;//状态栏高度,判断是否是数字，不是使用默认高度28
				_this.isImmersedStatusbar = plus.navigator.isImmersedStatusbar();//是否为沉浸式
