如果使用外部javascript，则模板标记'url'不起作用

Question

我使用“ google-map api”创建了django程序。从“ map.js”读取“ mapinit（json-data）”

<body onload="mapinit('{{ data }}')">

    <!-- create a map area with shop information -->
    <div class="wrapper">
        <div id="shopinfomation"></div>
        <div id="map_canvas1" style="width: 500px; height: 500px"></div>
    </div>

    <!-- post action from html is ok! -->
    <h3>category 1</h3>
    <form class="specific_form" action="{% url 'index_search' '1A' %}" method="POST">
        {% csrf_token %}
        <input type="submit" class="btn-flat-border" value="ramen" /> search ramen shops
    </form>

外部javascript有一些动作，例如ajax，重定向。现在，我直接在写网址。

// get a shop detail
$.ajax({
    type: "POST",
    url: "/gmarker/search/detail/" + json.shops[i]['place_id'],
    beforeSend: function(xhr, settings) {
        xhr.setRequestHeader("X-CSRFToken", Cookies.get('csrftoken'));
    }
}).done(function(data){
    shopinfomation.innerHTML = 'ajax success. shop information...';
}).fail(function(){
    shopinfomation.innerHTML = 'ajax error.';
});

我想用这个。

console.log("{% url 'index_search' '2' %}")

我想要。

/gmarker/search/2

但是chrome输出是...来的是同一个。

{% url 'index_search' '2' %}

urlpatterns = [
    path('', views.index, name='index'),
    path('search/<str:searchcode>', views.index, name='index_search'),
    path('search/detail/<str:place_id>', views.searchdetail, name='detail_search'),
    path('result/<str:searchcode>', views.index, name='index_result'),
]

外部javascript无法读取模板标记？
