how to run command stored as a string other than eval()

hi,

my code looks like this:

function getById(ID){

    var returnArray=[];

    for(var i= 0;i<ID.length;i++){

        returnArray.push("sap.ui.getCore().byId"+'('+'"'+ID[i]+'"'+')');

}

    return returnArray;

}

var x=getById(["miRequestDateDatePicker","miApprovalDateDatePicker"]);

        for(var i=0;i< x.length;i++){

            x[i]=x[i].concat(".setEditable"+'('+mode+')'+';');

            console.log(x[i]);

            //eval(x[i]);

        };

my array elements looks like this

x[0]="sap.ui.getCore().byId("miRequestDateDatePicker").setEditable(true);" i need to run this code in place of //eval(x[i]),

please suggest me a solution other than eval();

regards

Ajaay
