先上代码:
这是视图site/reg.php里

    $cs = Yii::app()->getClientScript();
    $cs->registerScriptFile('/js/verify-code.js',CClientScript::POS_END);

这是layout/main.php里

$commonValue = json_encode([
            'SmsVerifycodeUrl' => Yii::app()->createAbsoluteUrl('site/SendSmsCode'),
            'WaitSecond' => WapMember::DEFAULT_INTERVAL,
    ]);
Yii::app()->clientScript->registerScript("var commonValue = $commonValue",CClientScript::POS_END);

这是verify-code.js文件里

var initSecond = (typeof CommonValue.WaitSecond) == "undefined" ? 180 : CommonValue.WaitSecond,
    waitSecond =initSecond,
    SmsVerifyCode = function(btn, form) { this.getBtn = btn; this.form = form;},
       SCF;

这是chrom浏览器报的错
verify-code.js:1 Uncaught ReferenceError: CommonValue is not defined
