Unable to access codebehind variable in javascript in the aspx page

Question

I am trying to access a string from code behind into javascript in aspx page

code behind

  protected void btnSearch_Click(object sender, EventArgs e)
        {            
            List<string> imageList = new List<string>();
            string images="";
            imageList = GetMatchingImages(@"C:\Users\Shahzad\Documents\Visual Studio 2013\Projects\ImageSearchEngine\ImageSearchEngine\Images", txtSearch.Text);

            foreach (var image in imageList)
            {
                images += "\"" + image + "\",";
            }
            images ="["+ images.Substring(0, images.Length - 1)+"]";

        }

        public List<string> GetMatchingImages(string path, string keyword)
        {
            var matches = new List<string>();

            var images = System.IO.Directory.GetFiles(path);

            foreach (var image in images)
            {
                if (image.Contains(keyword))
                {
                    matches.Add(image);
                }
            }

            return matches;
        }

and in the aspx page

<script type="text/javascript">
     var imagesList;
     function getImages()
     {
         return <%=images%>;
     }
     imagesList = getImages();
 </script>

but it is giving error 'images does not exist in the current context' plz help me find out where I am making the mistake

This must be issue of the scope of images variable. Try declaring it outside btnSearch_Click function.

This could possibly fix the problem as images is currently inaccesible outside of this function.

Thanks, zryw141

Outside of the function and protected or public :-)
