麻烦看一下我抽取出来的案例

帮忙看一下，地图遮挡问题很久了，样式z-index，无效，真机还是被挡住了。下面这个是一个页面的部分案例，我抽取出来了，搜索框和地址，是需要浮动在map组件之上的
<template>
<view class="content">
<view class="main">
<view class="map_container">
<map class="map" id="map" style="width: 100%; height: 100%" :longitude="longitude" :latitude="latitude" :markers="markers"
bindmarkertap="makertap" :show-location="isshowlocation">
</map>
<!-- 地址显示 -->
<view class="adress-view">
北京市海淀区西三环路，玉渊潭桥
</view>
</view>
</view>
<!-- 搜索 -->
<view class="search-top">
<view class="image-search">
<!-- <cover-image src="../../static/main/Search.png" alt=""></cover-image> -->
</view>
<input type="text" value="" placeholder="请输入搜索位置" placeholder-style="color:#9E9E9E;font-size:14px;"/>
</view>
</view>
</template>
<script>
export default {
data() {
return {
latitude: 39.915,
longitude: 116.404,
markers: [], //气泡
isshowlocation: true, //默认显示我的位置
ispolice:false,//默认隐藏
}
},
onLoad() {
},
methods: {
}
}
</script>
<style lang='scss' scoped>
