I want to display multiple markers on Google map.I am using for each loop to iterate over the model list that contains latitude and longitude.But function is called and it does not show a map.

code:

JavaScript

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"> 
     </script>
     <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js? 
      sensor=false"></script>
      <script type="text/javascript">
    $(document).ready(function () {
    alert("working");
    @foreach(var item in Model)
  {

    <text>
    var markerlatLng = new google.maps.LatLng(item.latitude,item.longitude);


  //  var latlng = new google.maps.LatLng(markerlatLng);
    var options = {
        zoom: 14, center: markerlatLng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };

    var map = new google.maps.Map(document.getElementById
          ("map_canvas"), options);


    var marker = new google.maps.Marker({
        position: markerlatLng,
        map: map_canvas,
    });
 </text>
   }
   });
  </script>
