JSON 内で if ステートメントを使用する方法 コードは次のとおりです。 ...................................................................

var config =
             [
                {
                    "name"      : "SiteTitle",
                    "bgcolor"   : "",
                    "color"     : "",
                    "position"  : "TL",
                    "text"      : "step1",
                    "time"      : 5000
                },
                {
                    "name"      : "Jawal",
                    "bgcolor"   : "",
                    "color"     : "",
                    "text"      : "step2",
                    "position"  : "BL",
                    "time"      : 5000
                },
                {
                    "name"      : "Password",
                    "bgcolor"   : "",
                    "color"     : "",
                    "text"      : "step3",
                    "position"  : "TL",
                    "time"      : 5000
                }
            ],

            //define if steps should change automatically
            autoplay    = false,
            //timeout for the step
            showtime,
            //current step of the tour
            step        = 0,
            //total number of steps
            total_steps = config.length;

これは、次のような必要な結果です。

    var config =
         [

    if(page==true)  {               
            {
                "name"      : "SiteTitle",
                "bgcolor"   : "",
                "color"     : "",
                "position"  : "TL",
                "text"      : "step1",
                "time"      : 5000
            },
            {
                "name"      : "Jawal",
                "bgcolor"   : "",
                "color"     : "",
                "text"      : "step2",
                "position"  : "BL",
                "time"      : 5000
            }
    } else {
            {
                "name"      : "Password",
                "bgcolor"   : "",
                "color"     : "",
                "text"      : "step3",
                "position"  : "TL",
                "time"      : 5000
            }
    }
        ],

            //define if steps should change automatically
            autoplay    = false,
            //timeout for the step
            showtime,
            //current step of the tour
            step        = 0,
            //total number of steps
            total_steps = config.length;

実際、この方法は正しくなく、JavaScript 構文エラーになります。

これは通常のJavaScriptであり、JSONではありません。ifステートメントを外部に移動します。

if (page) {
    var config = [
        {
            "name"      : "SiteTitle",
            "bgcolor"   : "",
            "color"     : "",
            "position"  : "TL",
            "text"      : "step1",
            "time"      : 5000
        }, {
            "name"      : "Jawal",
            "bgcolor"   : "",
            "color"     : "",
            "text"      : "step2",
            "position"  : "BL",
            "time"      : 5000
        }
    ];
} else {
    var config = [
        {
            "name"      : "Password",
            "bgcolor"   : "",
            "color"     : "",
            "text"      : "step3",
            "position"  : "TL",
            "time"      : 5000
        }
    ];
}

またはおそらくこれ：

 var config =
  (page == true) ?
     [             
        {
            "name"      : "SiteTitle",
            "bgcolor"   : "",
            "color"     : "",
            "position"  : "TL",
            "text"      : "step1",
            "time"      : 5000
        },
        {
            "name"      : "Jawal",
            "bgcolor"   : "",
            "color"     : "",
            "text"      : "step2",
            "position"  : "BL",
            "time"      : 5000
        }
  :
        {
            "name"      : "Password",
            "bgcolor"   : "",
            "color"     : "",
            "text"      : "step3",
            "position"  : "TL",
            "time"      : 5000
        }
    ];
