Question

我正在尝试在我的Express App中使用这个谷歌地图代码，但它给了我一个syntaxError。我已经将错误过滤到了这个函数：

  <% var map; %>
  <% function initMap() { %>
  <%  map = new google.maps.Map(document.getElementById('map'), { %>
  <%    center: {lat: -34.397, lng: 150.644}, %>
  <%    zoom: 8 %>
  <%  }); %>
  <% }; %>

错误消息并没有太大帮助：

SyntaxError: Unexpected token ; in C:\proyectos\google-location-api\views\resultados.ejs while compiling ejs

If the above error is not helpful, you may want to try EJS-Lint:

有什么想法吗？

Answer 1

我猜这是因为你在每一行都有<%和%>，并建议让它更清洁，以便正确解析它

<%
    var map;

    function initMap() {
        map = new google.maps.Map(document.getElementById('map'), {
            center: {
                lat: -34.397,
                lng: 150.644
            },
            zoom: 8
        });
    };
%>

Answer 2

删除%%标记之前和<％标记之后的空格。请参阅https://github.com/mde/ejs/issues/334

<%var map;%>
  <%function initMap(){%>
  <%map = new google.maps.Map(document.getElementById('map'), {%>
  <%center: {lat: -34.397, lng: 150.644},%>
  <%zoom:8%>
  <%});%>
  <%};%>```
