通过AJAX调用ASP.NET MVC控制器明确 [英] Calling ASP.NET MVC Controller explicitly via AJAX

问题描述

我知道，我可以用下面这段code刷新一个div：

I know that I can use following piece of code to refresh a div:

<%=Ajax.ActionLink( "Update", "Administration", new AjaxOptions { UpdateTargetId = "grid", LoadingElementId = "grid-wait" } ) %>

不过，这将创建一个链接;用户必须点击它来获取视图刷新。

But this creates a link; user will have to click on it to get the view refreshed.

我怎样才能使它自动的，也就是说，像说，如果我想在网格每五秒钟之后被刷新？

How can I make it automatic, i.e., like say if I want the grid to be refreshed after every five seconds?

推荐答案

试试这个：

<p id="CurrentDateTime"></p>

<script src="../../Scripts/jquery-1.3.2.min.js" type="text/javascript"></script>

<script type="text/javascript">
    window.setInterval(updateDateTime, 5000);
    function updateDateTime() {
        $.get("GetCurrentDate?rnd=" + Math.random(1000), {}, function (r) {
            $("#CurrentDateTime").html(r);
        }, "text");
    }
</script>

---

public ActionResult GetCurrentDate()
{
    return Content(DateTime.Now.ToString("U"));
}
