单页面情况下laypage开启时hash的优化方法（代码）

//渲染分页
  Class.prototype.render = function(load){
    var that = this
    ,config = that.config
    ,type = that.type()
    ,view = that.view();
    
    if(type === 2){
      config.elem && (config.elem.innerHTML = view);
    } else if(type === 3){
      config.elem.html(view);
    } else {
      if(doc[id](config.elem)){
        doc[id](config.elem).innerHTML = view;
      }
    }
    config.jump && config.jump(config, load);
    
    var elem = doc[id]('layui-laypage-' + config.index);
    that.jump(elem);
    
    if(config.hash && !load){
      // location.hash = '!'+ config.hash +'='+ config.curr;   // 屏蔽掉该行，修改为下一行
      location.hash = location.hash.substr(0,location.hash.indexOf("#!")==-1 ? 99999:location.hash.indexOf("#!")) + '#!'+ config.hash +'='+ config.curr;
    }
    
    that.skip(elem);
  };

//开启HASH
        laypage.render({
            elem: 'test-laypage-demo5'
            ,count: 500
            //,curr: location.hash.replace('#!fenye=', '') //获取hash值为fenye的当前页
            ,curr: location.hash.indexOf("#!")==-1 ? "" : location.hash.substr(location.hash.indexOf("#!"),).replace('#!fenye=', '')//获取hash值为fenye的当前页
            ,hash: 'fenye' //自定义hash值
        });
