Map显示TypeError：$不是wordpress中的函数

Question

我想在网站上显示谷歌地图。我不想使用embed方法，所以使用async defer方法。

奇怪的是我的代码在html文件中工作正常但是，当我在wordpress中使用它时我得到TypeError：$不是函数错误。

当我在wordpress中使用时，如何在html文件和typeError中没有类型错误？

 <script>
  var rating;
  var address;
  var name;
  var infoWindow = null;
  function initMap() {
    var map = new google.maps.Map(document.getElementById('mapDiv'), {
      center: {lat: 33.531495, lng: -88.42207},
      zoom: 19
    });
    var infowindow = new google.maps.InfoWindow();
    var service = new google.maps.places.PlacesService(map);
    service.getDetails({
      placeId: 'ChIJJdJXNmjphogRo-W21kkhbJg'
    }, function(place, status) {
      if (status === google.maps.places.PlacesServiceStatus.OK) {
        rating = place.rating;
        name = place.name;

        //var labelIndex = 50;
        address = "<div>" + place.formatted_address + "</div>"
        var marker = new google.maps.Marker({
            map: map,
            position: place.geometry.location,

        });

          infowindow.setContent('<div><strong>' + place.name + '</strong><br>' +
          place.formatted_address + '</div>');

          infowindow.open(map, marker);


         google.maps.event.addListener(map, 'idle', function(e) {

Answer 1

尝试使用jQuery而不是$，因为如果我记得，wordpress使用jQuery.noConflict()模式。

例：

if ( jQuery( ".place-card" ).length === 0 ) { ...

Answer 2

将每个$符号更改为jQuery

wordpress不支持$

Answer 3

最好将整个功能放在文档就绪功能中。因此脚本在页面加载后执行。你可以像这样保持$符号：

jQuery(document).ready(function( $ ) {

  // Your function goes here...
  if ( $( ".place-card" ).length === 0 ) {
   //...
  }

});
