jquery利用ajax调用后台方法实例

语法:
$(function(){
    var callback = function(r){  //r表示后台数据返回的数据.
    }
    $.get("",callback);   //引号里面写方法的路径
});

这样就可以得到后台方法得到的数据显示在html前端了.

以下是工作中写的一段js和后台方法:

js:

$(function(){
    var callback = function (r) {
        var data = "<marquee width='853;' height='250px;' scrollamount='2' scrolldelay='4' direction='up' behavior='loop' onmouseout='this.start()' onmouseover='this.stop()'><ul>"
        var data2 = "<div class='marquee_div'><span onclick='closeList()'><img src='Images/关闭icon.png' class='closeImg ml_fix_png' /></span>优惠名单</div>";
        for (var i = 0; i < r.length; i++) {
            data += ("<li><label>" + r[i].time + "</label><span>" + r[i].CustomerName + "</span>申请试用成功获得购买年服务年费9折优惠,恭喜!</li>");
        }
        data += "</marquee></ul>";
        $("#01_companys").html(data);
        var t_data2 = "";
        for (var i = 0; i < r.length; i++) {
            if (i % 2 == 0) {
                t_data2 += "</div><div class='listTitle'>";
            }
            t_data2 += "<div style='width:49%; height:40px; line-height:40px; float:left'>" + (i + 1) + "." + r[r.length - i - 1].CustomerName + "</div>";
        }
        $("#01_list").html(data2 + (t_data2.length > 0 ? t_data2.substr(6, t_data2.length - 6) : "") + "</div>");
    }
    $.get("/activity/trycompany", callback);
});

后台代码(mvc4):

public ActionResult TryCompany()
        {
            string CustomerType = Res.CustomerType.TestCustomer.ToString();
            IList<Customers> vlist = o_Res.GetHtmlCustomers(1, 100, out pCount, (a => a.CustomerType == CustomerType));
            var list = vlist.ToList().ConvertAll(s =>
            {
                return new { s.CustomerName, time = s.AddDate.HasValue ? s.AddDate.Value.ToString("MM-dd HH:mm") : "" };
            });
            return Json(list, JsonRequestBehavior.AllowGet);
        }

后台得到一个list,jq调用,遍历,然后显示在前端.

一个很简单的例子,肯定还有更简单的办法,等以后来挖掘.
