if else语句中更改Jquery变量

Question

---原始代码----

$(function () {

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

 });

当rlt = true时,我想要十字准线:{mode:"x"}在选项变量中.

以下是我的代码,但它不正确.是否有人可以指出错误？

谢谢!

$(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" }
        };  

    }
 });

适合我,但你可以这样写:

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

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