[英]how to send two parameters with livewire emit in javascript?
[英]Livewire.emit is not a function
我刚刚学会了如何在 Livewire 中使用带有 javascript 的谷歌地图。 我做了一个测试项目,一切对我来说都很好。 尝试将我的项目移动到生产项目时,我收到以下错误:
Livewire.emit 不是 function
我正在使用谷歌搜索框:
<input id="pac-input" class="controls" type="text" placeholder="Search Box" />
<div id="map"></div>
搜索效果很好。 但我需要将纬度和经度发送给 Livewire 监听器
Livewire.emit('getLatitude', place.geometry['location'].lat());
Livewire.emit('getLongitud', place.geometry['location'].lng());
正如我在测试项目中提到的那样,它对我来说效果很好,但在生产性项目中却不行。 检查主标签是否为 DIV,我尝试使用 @push @livewirescripts 并无法检测到问题
我使用的完整 javascript 代码:
<script>
function initAutocomplete() {
const map = new google.maps.Map(document.getElementById("map"), {
center: { lat: -35.2385, lng: -65.6740 },
zoom: 6,
mapTypeId: "roadmap",
});
// Create the search box and link it to the UI element.
const input = document.getElementById("pac-input");
const searchBox = new google.maps.places.SearchBox(input);
map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);
// Bias the SearchBox results towards current map's viewport.
map.addListener("bounds_changed", () => {
searchBox.setBounds(map.getBounds());
});
let markers = [];
// Listen for the event fired when the user selects a prediction and retrieve
// more details for that place.
searchBox.addListener("places_changed", () => {
const places = searchBox.getPlaces();
if (places.length == 0) {
return;
}
// Clear out the old markers.
markers.forEach((marker) => {
marker.setMap(null);
});
markers = [];
// For each place, get the icon, name and location.
const bounds = new google.maps.LatLngBounds();
places.forEach((place) => {
if (!place.geometry || !place.geometry.location) {
console.log("Returned place contains no geometry");
return;
}
const icon = {
url: place.icon,
size: new google.maps.Size(71, 71),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(17, 34),
scaledSize: new google.maps.Size(25, 25),
};
// Create a marker for each place.
markers.push(
new google.maps.Marker({
map,
icon,
title: place.name,
position: place.geometry.location,
})
);
if (place.geometry.viewport) {
// Only geocodes have viewport.
bounds.union(place.geometry.viewport);
} else {
bounds.extend(place.geometry.location);
}
/* document.getElementById('lat-span').value = (place.geometry['location'].lat());
document.getElementById('lon-span').value = (place.geometry['location'].lng());
document.getElementById('location-snap').value = place.formatted_address; */
/* document.getElementById('lat-span').innerHTML = (place.geometry['location'].lat());
document.getElementById('lon-span').innerHTML = (place.geometry['location'].lng());
document.getElementById('location-snap').innerHTML = place.formatted_address; */
Livewire.emit('getLatitude', place.geometry['location'].lat());
Livewire.emit('getLongitud', place.geometry['location'].lng());
});
/* console.log(searchBox); */
map.fitBounds(bounds);
});
}
我可以尝试修复它吗? 谢谢你的时间
我通过如下设置属性来解决它:
@this.set('latitud', place.geometry['location'].lat());
@this.set('longitud', place.geometry['location'].lng());
