asp.net mvc 简单搜索功能

View中代码：

<input type="text" class="searchText" id="searchText"/>
                        <input type="button" value="" onclick="Cheak()" class="searchBtn" id="searchBtn"/>
                        <script type="text/javascript">
                            function Cheak() {
                                var keys = $("#searchText").val();
                                if (keys.trim() == "")
                                { alert("请输入要搜索的内容"); return false; }
                                if (keys == "--" || keys == "'")
                                { alert("请勿输入非法字符"); return false; }

                                window.location.href = "/Search/SearchList/"+keys.toString();
                            }
                        </script>

Controller中代码：

public ActionResult SearchList(string key)
        {
            if (key.Trim() != "" && key.IndexOf("'") <  && key.IndexOf("--") < )
            {
                var pro = (from ps in db.ProductInfoes where ps.productName.Contains(key) orderby ps.inDate descending select ps).ToList();
                if (pro.Count() > )
                {
                    StringBuilder proList = new StringBuilder();
                    foreach (var p in pro)
                    {
                        proList.Append("<li><a href=\"/Product/Details/" + p.ID + "/" + p.productType + "\">");
                        proList.Append("<div class=\"infoImg\"><img src=\"/Content/productImg/" + p.productPicTName + "\"/></div>");
                        proList.Append("<div class=\"infoName\">" + p.productName + "</div>");
                        proList.Append("</a></li>");
                    }
                    ViewData["proLists"] = proList.ToString();
                }
                else
                    ViewData["proLists"] = "没有匹配的内容！";

            }
            return View();
        }
