yii2在视图中注册js代码

Question

在yii2视图中注册js代码的最佳方法是什么？

1

<?php
    $this->registerJs(
    '$("document").ready(function(){ alert("hi"); });'
    );
  ?>

2

<?php 
     $this->registerJs('alert("hi");', View::POS_READY);
?>

3

<?php 
  $script = "function test() { alert('hi');}";    
  $this->registerJs($script, View::POS_END, 'my-options'); 
?>

Answer 1

Yii2,在视图中编写代码

<h2>Content</h2>
<?php
$script = <<< JS
    alert("Hi");
JS;
$this->registerJs($script);
?>

Answer 2

<?php 
$this->registerJs( <<< EOT_JS_CODE

  // JS code here

EOT_JS_CODE
);
?>

所以你不必转义js代码
