js基于Layui模块化封装

//设置body高度
$(function () {
    var topHei = 0;
    var CH = window.innerHeight || document.documentElement.clientHeight;
    document.getElementsByTagName("body")[0].style.height = CH - topHei + 'px';
    return CH - topHei;
});

//-------------对UI中表格进行模块化封装处理-----------------------------------
var laytable;
//基础参数配置
var baseCfg = {
    datatype: 'table',
    page: { //支持传入 laypage 组件的所有参数（某些参数除外，如：jump/elem） - 详见文档
        layout: ['limit', 'count', 'prev', 'page', 'next', 'skip'] //自定义分页布局
                , groups: 3 //只显示 1 个连续页码
                , first: false //不显示首页
                , last: false //不显示尾页
                , limit: 5
                , curr: location.hash.replace('#!fenye=', '') //获取起始页
  , hash: 'fenye' //自定义hash值
    }
  , height: 415

  , method: "post"
