bug: 页面搜索返回的列表在真机测试是会出现不显示问题?
造成原因:在小程序map组件的同一区域,map组件的视图层比普通的文本视图层要高,所以在真机会遮挡!
解决办法:将该文本视图采用cover-view,放在map中。
感谢: 感谢Lrj_estranged指出问题!
效果图
实现原理
通过高德地图的微信小程序开发API(getInputtips),实现关键词获取对应提示列表,同时返回location。
WXML
<view class="map-inputtips-input"> <input bindinput="bindInput" placeholder="搜索" focus="true" /> </view> <view class="map_container"> <map class="map" latitude='{{latitude}}' longitude='{{longitude}}' markers='{{markers}}'> <cover-view class="map-search-list {{isShow ? '' : 'map-hide'}}"> <cover-view bindtouchstart="bindSearch" wx:key="searchId" data-keywords="{{item.name}}" data-location="{{item.location}}" class="map-box" wx:for="{{tips}}"> {{item.name}} </cover-view> </cover-view> </map> </view>
WXSS
.map-inputtips-input{ height: 80rpx; line-height: 80rpx; width: 100%; box-sizing: border-box; font-size: 30rpx; padding: 0 10px; background-color: #fff; position: fixed; top: 0; left: 0; z-index: 1000; border-bottom:1px solid #c3c3c3; }
.map-inputtips-input input{ border: 1px solid #ddd; border-radius: 5px; height: 60rpx; line-height: 60rpx; width: 100%; box-sizing: border-box; padding: 0 5px; margin-top: 10rpx; }
.map-box{ margin: 0 10px; border-bottom:1px solid #c3c3c3; height: 80rpx; line-height: 80rpx; }
.map-box:last-child{border: none;}
.map-search-list{ position: fixed; top: 80rpx; left: 0; width: 100%; z-index: 1000; background-color: #fff; }
JS
const app = getApp();
const amap = app.data.amap;
const key = app.data.key;
Page({
data: {
isShow: false,
tips: {},
longitude: '',
latitude: '',
markers: []
},
onLoad() {
var _this = this;
wx.getLocation({
success: function(res) {
if (res && res.longitude){
_this.setData({
longitude: res.longitude,
latitude: res.latitude,
markers:[{
id:0,
longitude: res.longitude,
latitude: res.latitude,
iconPath: '../../src/images/ding.png',
width:32,
height:32
}]
})
}
}
})
},
bindInput: function (e) {
var _this = this;
var keywords = e.detail.value;
var myAmap = new amap.AMapWX({ key: key });
myAmap.getInputtips({
keywords: keywords,
location: '',
success: function (res) {
if (res && res.tips) {
_this.setData({
isShow: true,
tips: res.tips
});
}
}
})
},
bindSearch: function (e) {
var keywords = e.target.dataset.keywords;
var location = e.target.dataset.location.split(',');
this.setData({
isShow: false,
longitude: location[0],
latitude: location[1],
markers: [{
id: 0,
longitude: location[0],
latitude: location[1],
iconPath: '../../src/images/ding.png',
width: 32,
height: 32,
anchor: { x: .5, y: 1 },
label: {
content: keywords,
color: 'blue',
fontSize: 12,
borderRadius: 5,
bgColor: '#fff',
padding: 3,
x: 0,
y: -50,
textAlign: 'center'
}
}]
})
}
})
总结
- 输入框事件获取关键字,通过关键字获取展示列表;
- 列表选择事件,获取对应的location,并通过map组件的 markers 属性标记该坐标。
