Dynamic javascript in ASP.Net MVC 3.0+Razor - asp.net-mvc-3

Question

I have a javascript that must generate in runtime.The text of script is generate in controller class :
private string mapString
{
get
{
Locations loc = new Locations();
string appPath = Request.ApplicationPath;
loc.ReadXml(Path.Combine(Request.MapPath(appPath) + "\\App_Data", "Locations.xml"));
StringBuilder sb = new StringBuilder();
for (int i = 0; i < loc.Specfications.Count; i++)
{
sb.Append("var myLatLng" + i.ToString() + "= new google.maps.LatLng(" + loc.Specfications[i].Y.ToString() + "," +
loc.Specfications[i].X.ToString() + ");");
sb.Append(" var beachMarker" + i.ToString() + " = new google.maps.Marker({position: myLatLng" + i.ToString() + ",map: map,icon: image,title:'" + loc.Specfications[i].Title + "'});");
....
...
...
ViewData["MapString"] = mapString;
When I use it in script tag :
<script type="text/javascript">
function initialize() {
#Server.HtmlDecode(ViewData["MapString"].ToString())
}
</script>
It dosen't return a true text and it retruns something like this:
contentString0 = '<table width="100%" style="font-family: tahoma; text-align: right; font
**update : The site didn't show my question correctly ,I want to show "'<" but it show "'<"
but it must return :
contentString0 ='
you see that it convert "'<" to "'<" .
But when I use : #Server.HtmlDecode(ViewData["MapString"].ToString()) out of script tag ,all things is OK.

You may want to do it this way, which I think is going to be more flexible than generating code in your controller :
Controller action :
public JsonResult GetCoords()
{
// your code here - im putting a generic result you may
// need to put some logic here to retrieve your location / locations
var result = new { lon = "51.0000", lat = "23.0000" };
return Json(result, JsonRequestBehavior.AllowGet);
}
in your view add :
<script type="text/javascript">
$(document).ready(function () {
$.getJSON('/YourController/GetCoords', function (jsonData) {
var lon = jsonData.lon;
var lat = jsonData.lat;
yourGoogleMapFunction(lon, lat);
});
});
</script>
