前端jquery分页插件推荐

发布:2018-12-28 10:53 浏览: 评论(

很久没更新文章了,最近项目需要使用前端来做分页,于是找了一款现有的jquery分页插件进行修改了一下,增加了些新功能以及加大了兼容性,其本质其实就是使用$.ajax()方法进行包装,把修改过后的代码贴出来给大家吧(末尾提供下载)

/// 辅助方法:格式化字符串

    var str = arguments[0];

    for (var i = 1; i < arguments.length; i++) {
        var reg = new RegExp('\\{' + (i - 1) + '\\}', 'gm');

        str = str.replace(reg, arguments[i]);
    }

    return str;
