Question

—Original code—-

$(function () {

    var options = {
    xaxis: { mode: "time", tickLength: 5 },
    selection: { mode: "x" },
    crosshair: { mode: "x" }
    };

 });

I want crosshair: { mode: “x” } to be inside of options variable when rlt=true.

Following is my code, but it’s not correct.Is there anyone can point error out?

Thanks!

$(function () {
    var rlt = true;
    var options;
    if(rlt){
        options = {
        xaxis: { mode: "time", tickLength: 5 },
        selection: { mode: "x" },
        crosshair: { mode: "x" }
        };
    }else{
        options = {
        xaxis: { mode: "time", tickLength: 5 },
        selection: { mode: "x" }
        };  

    }
 });

works for me, but you can write it this way:

var rlt = true;
var options = {
    xaxis: { mode: "time", tickLength: 5 },
    selection: { mode: "x" }
    };  

if (rlt) options.crosshair = { mode: "x" }
