直接贴代码了：

@section headSection
{
    <script type="text/javascript">
    $(document).ready(function () {
        var substringMatcher = function(strs) {
          return function findMatches(q, cb) {
            var matches, substringRegex;

            // an array that will be populated with substring matches
            matches = [];

            // regex used to determine if a string contains the substring `q`
            substrRegex = new RegExp(q, 'i');

            // iterate through the pool of strings and for any string that
            // contains the substring `q`, add it to the `matches` array
            $.each(strs, function(i, str) {
              if (substrRegex.test(str)) {
                matches.push(str);
              }
            });

            cb(matches);
          };
        };

        var states = ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California',
          'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii',
