解决JQuery中datatables设置隐藏显示列多次提交后台刷新数据的问题

此次项目开发过程中用到了Jquery的Datatables插件，无疑他是数据列表展示，解决MVC中同步过程中先走控制器后返回视图，查询数据过程中无法提示等待的弊端，

而且他所提供的各种方法也都有较强的实用性。但是再好的程序也会有瑕疵，项目开发中就遇到了其提供的设置隐藏显示列的方法 table.fnSetColumnVis(colShowDic_key[i], true);//colShowDic_key[i]为列的索引。会多次提交刷新数据（有多少列会提交刷新多少次）。

为解决这个问题尝试了很多种方法依然存在各种问题：最终换了个角度思考，既然在列表中更换隐藏显示列不行，为何不重新加载列表呢？

于是datatables中的参数：aoColumns  本身即是一个数组，我们换成了变量，根据设置的隐藏显示列重新定义该数组，然后调用加载列表的方法重新加载列表：

代码如下：

//初始化设置显示列弹出层数据
function instailSetColShow() {
    var left = document.getElementById("selectBefor");
    var right = document.getElementById("selectAfter");

    left.options.length = 0;
    for (i = 0; i < colHiddenDic_key.length; i++) {
        left.options.add(new Option(colHiddenDic_value[i], colHiddenDic_key[i]));
    };

    right.options.length = 0;
    for (j = 0; j < colShowDic_key.length; j++) {
        right.options.add(new Option(colShowDic_value[j], colShowDic_key[j]));
    };
}

//导出选项卡
function selectMove() {
    var left = document.getElementById("selectBefor");
    var right = document.getElementById("selectAfter");

    while (true) {
        var index = left.selectedIndex;
        if (index < 0) {
            break;
        }
        right.options.add(new Option(left.options[index].text, left.options[index].value));
        left.options.remove(index);
    }

}

function selectBack() {
    var left = document.getElementById("selectBefor");
    var right = document.getElementById("selectAfter");

    while (true) {
        var index = right.selectedIndex;
        if (index < 0) {
            break;
        }
        left.options.add(new Option(right.options[index].text, right.options[index].value));
        right.options.remove(index);
    }
}

//重置显示、隐藏列
function ReSetShowCol() {
    //获取隐藏显示列
    GetHideShowCol();
    //获取列表显示列数组
    GetAoColumnShow();
    //设置列显示
    setShowCol();
    //关闭弹出层
    $("#setModal").modal("hide");
}

//获取显示隐藏列
function GetHideShowCol() {
    var right = document.getElementById("selectAfter");
    var left = document.getElementById("selectBefor");

    colShowDic_key.length = 0;
    colShowDic_value.length = 0;
    colHiddenDic_key.length = 0;
    colHiddenDic_value.length = 0;

    //获取显示列
    if (right.options.length > 0) {
        for (i = 0; i < right.options.length; i++) {
            //获取要添加到数据字典的键值对(显示列)
            colShowDic_key[i] = right.options[i].value;
            colShowDic_value[i] = right.options[i].text;
        }
    }
    //获取隐藏列
    if (left.options.length > 0) {
        for (i = 0; i < left.options.length; i++) {
            //获取要添加到数据字典的键值对(隐藏列)
            colHiddenDic_key[i] = left.options[i].value;
            colHiddenDic_value[i] = left.options[i].text;
        }
    }
}

//获取列表显示列数组
