I assume management.

Then get the management object of this toolbar through toobamanager = manage.toolbarmanager.

Each button can be disabled (ID) through toobamanage. Settings; Set to Unavailable

You need to get the button by passing its id to the management class.

The id can be filled in by itself at initialization.

Toolbar: {

Project: [{

Text: "new user",

id:'adduser '，

Click: addAdminUser,

Icon: "Add"

}, {

OK: Correct.

},{

Text: "Delete user",

Id: "delete user",

Click: disable checking lines,

Icon: "Lock"

}]

}

});

toobar manage . set disabled(' adduser ')；

toobar manage . set disabled(' deleteuser ')；
