Javascript, add string if true

Question

I need to modify this function:

function checkPermissions(fid, obj) {

$("#permissions_"+fid+"_canview").attr("checked", obj.checked);

}

if the param "n" is "true" then instead of #permissions it'll output #permissionsSet.

is that possible?

Are you familiar with the if statement?

OP clarified the question to be change this whether or not a 3rd parameter was provided. Here you go.

function checkPermissions(fid, obj, n) {
  var id = n !== undefined ? '#permissionsSet' : '#permissions';
  $(id + fid + "_canview").attr("checked", obj.checked);
}

Note: This function can be freely used with passing 2 or 3 parameters (or really any number).

checkPermissions(1, this);        // Ok n === undefined 
checkPermissions(1, this, true);  // Ok n === true
checkPermissions(1);              // Okish n and obj === undefined

I mean , if the 'n' is defined in the function callback fe. checkPermissions(1, this, true) then the 3th param is a 'n' but I need also to use the same function at the same time without the n param : checkPermission(1, this)

Aight, now when I check my checkbox, firebug says that the checkPermission function is undefined. My onClick callback: onClick="checkPermissions('.$gid.', this);"

@Lucas, this is likely a separate issue due to the ordering of javascript code after the definition of the onClick handler. You need to make sure the function is defined before the element to which you attach the handler

Thank you JaredPar, I got this working now. Thank you once again.

    $("#permissions" + ((n) ? "Set" : "") + "_"+fid+"_canview").attr("checked", obj.checked);
