我正在嘗試在 Google 地圖上顯示標記。對于某些診所，可能會有一個或多個位置。我正在使用 Laravel 并從 MySQL 數據庫中獲取緯度和經度值。當我編碼時，它只在一個位置顯示一個標記。沒有顯示多個標記。以下是視圖頁面中的代碼 @extends('user.layout.app') @section('content') <script src="{{ url('js/user/location.js') }}"></script> <div class="container-fluid add-location"> <div class="row"> <div class="col-md-12"> <div class="card"> <form method="post" action="" name="clinicssview" id="clinicssview" enctype="multipart/form-data" novalidate> {{ csrf_field() }} <div class="card-header"> <h4 class="card-title"> View Clinics </h4> </div> @if(!empty($errors->all())) <div class="row"> @foreach ($errors->all() as $error) <div class="col-lg-12"> <div class="alert alert-danger"> <span>{{ $error }}</span> </div> </div> @endforeach </div> @endif

在您的情況下，您在循環中設置地圖數據，for所以我猜每個循環它們都會生成新地圖，因此會覆蓋原始地圖。嘗試在for循環外設置地圖并使用這樣的標記位置設置位置。
function initMap() {
var locations = <?php echo $locations ?>;
var i;
var map = new google.maps.Map(document.getElementById('regularMap'), {
zoom: 4
});
for (i = 0; i < locations.length; i++) {
uluru = new google.maps.LatLng(parseFloat(locations[i]['locationLat']), parseFloat(locations[i]['locationLong']));
console.log(uluru);
var marker = new google.maps.Marker({
map: map,
position: uluru,
});
marker.setMap(map);
}
}
還要marker.setMap(map);在 for 循環中添加它。
希望這對您有所幫助。
