This is not the best practice to use js to manage your security. You should not show this column on your server side!
这不是使用 js 管理安全性的最佳实践。您不应在服务器端显示此列！

I had to dive into some legacy stuff today. One of the requirements was to conditionally set the visibility of some columns. There was a drop down on the page that set a category parameter in the where clause for the grid. Long story short, watching the change event of the drop down wasn't possible making most of the methods in the answers here invalid.
今天我不得不深入研究一些遗留的东西。其中一项要求是有条件地设置某些列的可见性。页面上有一个下拉菜单，可以在网格的 where 子句中设置类别参数。长话短说，观看下拉菜单的更改事件不可能使此处答案中的大多数方法无效。
I was able to use a ternary in the hidden param to set the visibility.
我能够在隐藏参数中使用三元组来设置可见性。
{
name: 'mfg',
index: 'mfg',
width: 150,
sortable: true,
hidden: $('#evCategory').val() == 'Calibration' ? false : true
},
And it simply evals to if the dropdown has a value of calibration hidden should be false, if calibration is not the value hidden should be true.
并且它只是评估下拉列表是否有校准隐藏的值应该是假的，如果校准不是隐藏的值应该是真的。
Might also be able to shorten it to;
也可以将其缩短为；
!$('#evCategory').val() == 'Calibration' || true
Although I haven't tested that.
虽然我没有测试过。
