我正在使用vue js,并且能够传递用户名。但是我无法传递lat和lng值。检查时,我可以发布用户名,但是lat和lng会为空。
我的html代码是
<form id="submitBox" method="POST" onSubmit="return false;" data-parsley-validate="true" v-on:submit="handelSubmit($event);">
<div id="map"></div>
<input name="lat" type="text" id="lat" v-model="lat"><br>
<input name="lng" type="text" id="lng" v-model="lng">
<input name="username" type="text" class="form-control" id="name" placeholder="Name" required="required" v-model="username" data-parsley-minlength="4"/>
</form>
在地图上单击时。我能够加载lat和lng值,但我不愿意通过
我的加载地图值的脚本是
<script>
//map.js
//Set up some of our variables.
var map; //Will contain map object.
var marker = false; ////Has the user plotted their location marker?
//Function called to initialize / create the map.
//This is called when the page has loaded.
function initMap() {
//The center location of our map.
var centerOfMap = new google.maps.LatLng(52.357971, -6.516758);
//Map options.
var options = {
center: centerOfMap, //Set center.
zoom: 7 //The zoom value.
};
//Create the map object.
map = new google.maps.Map(document.getElementById('map'), options);
//Listen for any clicks on the map.
google.maps.event.addListener(map, 'click', function(event) {
//Get the location that the user clicked.
var clickedLocation = event.latLng;
//If the marker hasn't been added.
if(marker === false){
//Create the marker.
marker = new google.maps.Marker({
position: clickedLocation,
map: map,
draggable: true //make it draggable
});
//Listen for drag events!
google.maps.event.addListener(marker, 'dragend', function(event){
markerLocation();
});
} else{
//Marker has already been added, so just change its location.
marker.setPosition(clickedLocation);
}
//Get the marker's location.
markerLocation();
});
}
//This function will get the marker's current location and then add the lat/long
//values to our textfields so that we can save the location.
function markerLocation(){
//Get location.
var currentLocation = marker.getPosition();
//Add lat and lng values to a field that we can save.
document.getElementById('lat').value = currentLocation.lat(); //latitude
document.getElementById('lng').value = currentLocation.lng(); //longitude
}
//Load the map when the page has finished loading.
google.maps.event.addDomListener(window, 'load', initMap);
</script>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js"></script>
我的Vue JS代码是
<script>
submitBox = new Vue({
el: "#submitBox",
data: {
lat : '',
lng : '',
username: '',
},
methods: {
handelSubmit: function(e) {
var vm = this;
data = {};
data['lat'] = this.lat;
data['lng'] = this.lng;
data['username'] = this.username;
$.ajax({
url: 'http://127.0.0.1:8000/api/add/post/',
data: data,
type: "POST",
dataType: 'json',
success: function(e) {
if (e.status)
{
alert("Success")
}
else {
vm.response = e;
alert("Failed")
}
}
});
return false;
}
},
});
</script>
我可以获取用户名。但是我正在获取lat和lng的空值。
但是,当我点击地图时,我可以打印LAT和LNG值,但是我无法传递相同的值。谁能帮我解决问题。
最佳答案
v模型无法识别您的“纬度”输入字段的value属性已通过编程方式进行了更改。相反,您可以执行以下操作:
<input name="lat" type="text" id="lat" ref="myLatField" v-model="lat">
methods: {
handelSubmit: function(e) {
var vm = this;
data = {};
data['lat'] = this.$refs.myLatField.value;
...
