MVC4中ajax分页技术实例

在这之前一直没有写过碰过MVC，更别说ajax，但是项目需要，只好边学边做了，希望跟我一样的朋友也可以看到文章，希望可以应用的到你们的项目中去。好了废话不多说，现在开始动手吧。

 

前台页面 Index.cshtml，这个页面主要是布局控件 引用样式和js

@{
    //收费查询页面   
    ViewBag.Title = "互联网云停车场-收费查询";
    @Scripts.Render("~/Scripts/jquery-1.7.1.min.js")
    @Scripts.Render("~/Scripts/class.js")
    @Scripts.Render("~/Scripts/Validate.js")
    @Scripts.Render("~/Scripts/main/Select.js")
    @Styles.Render("~/Content/GooutRecord.css")
    @Styles.Render("~/Scripts/PagePaging.js")
    Layout = "~/Views/Shared/_LayoutPageMu.cshtml";

     
}
 
<div class="Content_R">
    <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">

	  <button id="queryBtn"   rel="type1" value="查询"   >查询</button>

Select.js 这个脚本就是通过对control层的数据进行输出,其中重点就是分页技术的实现,代码很清晰

    var args = arguments;
    return this.replace(/\{(\d+)\}/g,
        function (m, i) {
            return args[i];
        });
}
//String的静态方法
String.format = function () {
    if (arguments.length == 0)
        return null;

    var str = arguments[0];
    for (var i = 1; i < arguments.length; i++) {
        var re = new RegExp('\\{' + (i - 1) + '\\}', 'gm');
        str = str.replace(re, arguments[i]);
    }
    return str;

}
