但是当我运行这个时，我的外部 javascript 捕捉到一个错误显示
Error: Syntax error, unrecognized expression: #builder/saveform
What is the error
什么是错误
回答by Michael St Clair
To change default action add it as the first argument in this format ['<controller>/<action>']
要更改默认操作，请将其添加为此格式的第一个参数 ['<controller>/<action>']
<?php $form = ActiveForm::begin(['action' => ['builder/saveform'],'options' => ['method' => 'post']]) ?>
Also, keep in mind that the method defaults to post, so specifying that is unnecessary.
另外，请记住该方法默认为 post，因此无需指定。

$form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data'], 'action' => Yii::$app->urlManager->createUrl(['site/signup'])]);
You can also use this snippet for custom form action and other attributes. createUrl method will not affect your url pattern.
您还可以将此代码段用于自定义表单操作和其他属性。createUrl 方法不会影响您的 url 模式。

Since there is still no accepted answer, the exact answer to your question is in the Error: "unrecognized expression: '#builder/saveform' ". You have your 'id' HTML tagof the Form being assigned a value of 'builder/saveform', which contains "/" - an illegal character in terms of HTML4 Specification. I suppose Yii has a "validation" in place resulting in your error.
由于仍然没有公认的答案，您的问题的确切答案是错误：“无法识别的表达式：'#builder/saveform'”。您将表单的'id' HTML 标记分配了一个值 'builder/saveform'，其中包含“/” - 根据HTML4 规范是非法字符。我想 Yii 有一个“验证”，导致你的错误。
Now, I believe you are trying to specify the relative URL for the Form submission. For that, please refer to Michael St Clair's answer.
现在，我相信您正在尝试为表单提交指定相对 URL。为此，请参阅 Michael St Clair 的回答。

<?php $form = ActiveForm::begin(['action' => 'index.php?r=builder/saveform','options' => ['method' => 'post']]) ?>
it is working but is it the proper way to write???
它正在工作，但它是正确的写作方式吗？？？
回答by Lionel Morrison
I was able to do it by adding the action into the options like so
我能够通过将操作添加到选项中来做到这一点
<?php $form = ActiveForm::begin(['id' => 'contact-form', 'options' => ['method' => 'post', 'action' => 'site/add']]); ?>

For Yii2
对于 Yii2
$form = ActiveForm::begin([
'id' => 'login-form',
'options'=>['autocomplete'=>'off','method' => 'post', ],
'action' => '/frontend/web/user-management/auth/login',
'validateOnBlur'=>false,
'fieldConfig' => [
'template'=>"{input}\n{error}",
],
]);
