这是我的代码,用于在客户端的谷歌地图中放置标记。如何使用vue js捕获这些值并发布该值?
<script>
function initMap() {
var uluru = {
lat: -25.363,
lng: 131.044
};
var mapDiv = document.getElementById('map');
var map = new google.maps.Map(mapDiv, {
zoom: 8,
center: uluru,
clickableIcons: true,
});
google.maps.event.addListener(map, 'click', function(e) {
if (map.getClickableIcons()) {
var Latitude = e.latLng.lat();
var Longitude = e.latLng.lng();
// add your new marker with this info.
var marker = new google.maps.Marker({
position: {
lat: Latitude,
lng: Longitude
},
map: map,
draggable: true,
});
map.clickableIcons = false;
// get latitude and longitude after dragging:
google.maps.event.addListener(marker, 'dragend',
function(marker){
var latLng = marker.latLng;
currentLatitude = latLng.lat();
currentLongitude = latLng.lng();
});
}
});
}
</script>
<div id="map"></div>
<!-- Replace the value of the key parameter with your own API key. -->
<script async defer src="https://maps.googleapis.com/maps/api/js?key=AIzaSyCu8vqg35dD4fNfxlI8ICoycehbL0F6bis&callback=initMap">
</script>
我的vue js代码是
<script>
submitBox = new Vue({
el: "#submitBox",
data: {
articles: [],
services: [],
lat : '',
lng : '',
username: '',
category: '',
subcategory: [],
},
methods: {
handelSubmit: function(e) {
var vm = this;
data = {};
data['lat'] = this.lat;
data['lng'] = this.lng;
data['username'] = this.username;
data['category'] = this.category;
data['subcategory'] = this.subcategory;
$.ajax({
url: 'http://127.0.0.1:8000/api/add/post/',
data: data,
type: "POST",
dataType: 'json',
success: function(e) {
if (e.status)
{
alert("Success")
window.location.href= "https://localhost/n2s/registersuccess.html";
}
else {
vm.response = e;
alert(" Failed")
}
}
});
return false;
}
},
});
</script>
我怎样才能捕获lat和lng值并使用ajax请求发布该值。如果有人请帮我实现同样的目标,那将是很棒的。我可以在地图上放置标记。我需要使用vue js发布lat和lng值?
您遇到的主要问题是您的Vue组件和与地图相关的代码是独立的,您需要找到一种在地图和Vue组件之间进行通信的方法。
通常,您在Vue组件中初始化地图,以便Vue组件负责地图及其数据/事件/等。
我不太了解谷歌地图API,但这样的事情应该有效:
const uluru = {
lat: -25.363,
lng: 131.044
};
const app = new Vue({
el: '#app',
data: {
lat: 0,
lng: 0,
},
methods: {
createMap() {
this.map = new google.maps.Map(this.$refs.map, {
zoom: 8,
center: uluru,
clickableIcons: true,
});
google.maps.event.addListener(this.map, 'click', e => {
if (!this.map.getClickableIcons()) {
return;
}
this.lat = e.latLng.lat();
this.lng = e.latLng.lng();
// add your new marker with this info.
const marker = new google.maps.Marker({
position: {
lat: this.lat,
lng: this.lng,
},
map: this.map,
draggable: true,
});
this.map.clickableIcons = false;
// get latitude and longitude after dragging:
google.maps.event.addListener(marker, 'dragend', marker => {
this.lat = marker.latLng.lat();
this.lng = marker.latLng.lng();
});
});
},
submit() {
// Do your AJAX request here with this.lat and this.lng
console.log('AJAX request');
console.log('Lat: ' + this.lat);
console.log('Lng: ' + this.lng);
},
},
});
function ready() {
app.createMap();
}
.map {
width: 400px;
height: 200px;
}
