jquery.autocomplete.min.js怎么实现动态数据

[wilson0424]

下面是jquery.autocomplete.min.js的一个简单的例子。
我想问是的怎么动态的跟后台交互，不是写死的，而是从数据库里面得到的。本人小白，最好是能有一个实例。前台后台的都有最好了。谢谢

<script type="text/javascript">
         var emails = [
             { name: "Peter Pan", to: "[e-mail]" },
             { name: "Molly", to: "[e-mail]" },
             { name: "Forneria Marconi", to: "[e-mail]" },
             { name: "Master <em>Sync</em>", to: "[e-mail]" },
             { name: "Dr. <strong>Tech</strong> de Log", to: "[e-mail]" },
             { name: "Don Corleone", to: "[e-mail]" },
             { name: "Mc Chick", to: "[e-mail]" },
             { name: "Donnie Darko", to: "[e-mail]" },
             { name: "Quake The Net", to: "[e-mail]" },
             { name: "Dr. Write", to: "[e-mail]" },
             { name: "GG Bond", to: "[e-mail]" },
             { name: "Zhuzhu Xia", to: "[e-mail]" }
         ];
  
             $(function() {
                 $('#keyword').autocomplete(emails, {
                     max: 12,    //列表里的条目数
                     minChars: 0,    //自动完成激活之前填入的最小字符
                     width: 400,     //提示的宽度，溢出隐藏
                     scrollHeight: 300,   //提示的高度，溢出显示滚动条
                     matchContains: true,    //包含匹配，就是data参数里的数据，是否只要包含文本框里的数据就显示
                     autoFill: false,    //自动填充
                     formatItem: function(row, i, max) {
                         return i + '/' + max + ':"' + row.name + '"[' + row.to + ']';
                     },
                     formatMatch: function(row, i, max) {
                         return row.name + row.to;
                     },
                     formatResult: function(row) {
                         return row.to;
                     }
                 }).result(function(event, row, formatted) {
                     alert(row.to);
                 });
             });

前端

 $(function () {
            var url = "/RepairIn/InitFailCode";
            $.ajax({
                type: "POST",
                async: false,
                url: encodeURI(url),
                success: function (data) {
                    $('#failCode').autocomplete(data, {
                        max: 10,    //列表里的条目数
                        minChars: 1,    //自动完成激活之前填入的最小字符
                        width: 300,     //提示的宽度，溢出隐藏
                        scrollHeight: 300,   //提示的高度，溢出显示滚动条
                        matchContains: true,    //包含匹配，就是data参数里的数据，是否只要包含文本框里的数据就显示
                        autoFill: false,    //自动填充
                        formatItem: function (row, i, max) {
                            return i + ':"' + row.Code + '"[' + row.Name + ']';
                        },
                        formatMatch: function (row, i, max) {
                            return row.Code + row.Name;
                        },
                        formatResult: function (row) {
                            return row.Code;
                        }
                    }).result(function (event, row, formatted) {
                        document.getElementById("failName").value = row.Name;
                        checkSubmit();
                    });
                }
            });
        });

后台返回JSON数组 public ActionResult InitFailCode() { List<object> items = new List<object>(); using (DataTable dt = _failCode.SelectFailCode("", "", 1)) { foreach (DataRow dr in dt.Rows) { var item = new { Code = dr["FAILURE_CODE"].ToString().Trim(), Name = dr["FAILURE_NAME"].ToString().Trim() }; items.Add(item); } } return Json(items, JsonRequestBehavior.AllowGet); }

再问下，那什么时候触发$.ajax。

再问下，那传值到后台，是怎么传过去了。（参数的传递） 谢谢

                        },
                        formatMatch: function (row, i, max) {
                            return row.Code + row.Name;
                        },
                        formatResult: function (row) {
                            return row.Code;
                        }
                    }).result(function (event, row, formatted) {
                        document.getElementById("failName").value = row.Name;
                        checkSubmit();
                    });
                }
            });
        });

后台返回JSON数组 public ActionResult InitFailCode() { List<object> items = new List<object>(); using (DataTable dt = _failCode.SelectFailCode("", "", 1)) { foreach (DataRow dr in dt.Rows) { var item = new { Code = dr["FAILURE_CODE"].ToString().Trim(), Name = dr["FAILURE_NAME"].ToString().Trim() }; items.Add(item); } } return Json(items, JsonRequestBehavior.AllowGet); }

在1楼的代码示命名， ajax url后面拼，或者是用 data:{param:param} 方式进行传递参数

页面加载时会自动触发
