<body class="row">
<div class="container body">
</div>
</body> for example, I have a requirement that I want to dynamically set the class style of body based on the result of a js method, and
switch between row and col.
the addClass, effect of trying to use jquery is not good.
is there any other way? does class support splicing? < body class= "+ Result () +" > something like this?
I finally implemented it with a variable set in the background of. I think there should be another way at the front end, right?
