Hide buttons in Datables for non-authorized users with Spring Security

Question

I need to hide buttons in Datables for non-authorized users.

In plain jsp I was used spring security tags to hide elements for non-authorized users.

E.g. hide delete button:

<sec:authorize access="hasRole('ROLE_ADMIN')"> <a href="delete/${author.id}">Delete</a></sec:authorize>

But in jquery datatables, buttons are come from inner javascript config. And I can't use spring security tags. E.g. delete button in DataTables:

"buttons": [
{
    text: "Delete",
    action: function (e, dt, button, config){
        //button onClick here
    }
}
]

Answer 1

Here's an example:

var authStatus = true; //your auth status variable from JSP

var buttons = [];

if (authStatus) {
    buttons = [
        {
            text: "Delete",
            action: function(e, dt, button, config) {
                //button onClick here
            }
        }
    ];
}

$('#example').DataTable({
    dom: 'Bfrtip',
    buttons: buttons,
});

You could instead write it inline with a ternary operator, but it won't be as clear.
