First go to the code:

This is the viewsite/reg.php

    $cs = Yii::app()->getClientScript();
    $cs->registerScriptFile(&#39;/js/verify-code.js&#39;,CClientScript::POS_END);

Copy after login

This is the layout/main.php

$commonValue = json_encode([
            &#39;SmsVerifycodeUrl&#39; => Yii::app()->createAbsoluteUrl(&#39;site/SendSmsCode&#39;),
            &#39;WaitSecond&#39; => WapMember::DEFAULT_INTERVAL,
    ]);
Yii::app()->clientScript->registerScript("var commonValue = $commonValue",CClientScript::POS_END);

Copy after login

This is the verify-code.js file

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

Copy after login

This is the error reported by the chrom browser
verify-code.js:1 Uncaught ReferenceError: CommonValue is not defined

Finally found:
It turned out to be writing

Yii::app()->clientScript->registerScript("var commonValue = $commonValue",CClientScript::POS_END);

Copy after login

is missing a parameter. The result is like this:

Yii::app()->clientScript->registerScript(&#39;commonValue&#39;,"var commonValue = $commonValue",CClientScript::POS_END);

Copy after login

CommonValue's POS_END is simply adjusted to POS_HEAD.

Or make sure $commonValue is placed before render('reg.php') in main.php. The two registerScripts are in order

ps: Can

verify-code.js return functions or objects instead of referencing global variables in this file?
I have maintained such code before, it is disgusting

The above is the code example of Yii creating variables in the view (protecting PHP code) and calling the previously created variables in the js file. Please pay attention to more related content PHP Chinese website (m.sbmmt.com)!
