jQuery Autocomplete Ajax WebService 多参数

两种不同的方式 注意参数

不同方法 能提交的参数不一样

Ajax只传term

WebService 传了str tb3 两个参数

关键代码

<script language="javascript" type="text/javascript">

        $(function() {
            $("#txtTest").autocomplete({
                minLength: 1,
                source: function(request, response) {
                    $.ajax({
                        url: "./Handler.ashx",
                        dataType: "json",
                        data: request,
                        success: function(data) {
                            response(data);
                            alert(data);
                            $('#it').val(data);
                        }
                    });
                }
            });


            $('#it').autocomplete({
                minLength: 1,

                        datatype: "json",
                        data: "{ 'str': '" + request.term + "','tb3':'" + $('#txtTest').val() + "' }",
                        type: "POST",
                        contentType: "application/json",
