jquery 表单下拉框(select)美化增加强版示例

function Getselect2ID(idd) {
    var data = $("#" + idd).select2("data");
    var datastring = "";
    $.each(data, function (key, val) {
        datastring = datastring + val.id + ",";
    });
    return datastring;
}
function ToggleProductList() {
    var sqlist = Getselect2ID("selectsq");
    if (sqlist.length > 0) {
        $("#divselectProduct").show();
      
    }
    else {
        $("#divselectProduct").hide();
    }
}
var data = $("#" + idd).select2("data")是获取select选中的数据

function GetCityData() { 
        var cityId = GetCity();
        $.ajax({
            type: "post",
            dataType: 'json',
            url: ajaxUrl,
            data: {
                Operate: "searchcitydata",
                txtsqname: $("#txtsqname").val(),
                txtspname: $("#txtspname").val(),
                txtsjname: $("#txtsjname").val(),
                CityId: cityId
            },
            success: function (data, textStatus) {
                if (data != null) {
                    var model = eval(data);
                    if (model != null && model != "undefined") {
                        //selectsq
                        var html = '';
                        $.each(model.ListSQ, function (key, val) {
                             
                            html = html + '    ' + val.Name + '';
                        });
                        $("#selectsq").append(html);
                    }
                    else {
                        alert("加载数据失败！"); return;
                    }
                }
            },
            complete: function (XMLHttpRequest, textStatus) {
            },
            error: function (e) {
                alert("加载数据错误！"); return;
            }
        });
}
