How to add js code to View in yii2

如果直接按如下方式添加,如:

<script>
$(function(){
  alert("aaa");
});
<script>

会提示出错。

因为view中添加js代码的前面没有引用juqery.js,默认全局的jquery则是在文件尾添加。

解决方法:

1、在代码前引入js文件(两种方式)

<?=Html::jsFile(&#39;@web/js/jquery.js&#39;)?>
<?php $this->registerJsFile(&#39;@web/js/jquery.js&#39;);?>

2、使用全局的js文件,例如:

<?php
$js = <<<JS
$(function(){
  alert("aaa");
});
JS;
$this->registerJs($js);
?>
