在yii2驗證以前執行一些額外自定義驗證

第一種

1. <?php
2. $js = <<<JS
3. $("#button").click(function(e){

1. if(驗證規則){
   $("form#{$model->formName()}").submit();
   }else{
   return false;
   }

1. })
2. JS;
3. $this->registerJs($js);

第二種

1. <?php
2. /**
3. * User: yiqing
4. * Date: 14-9-15
5. * Time: 下午12:09
6. */
7.  
8. namespace common\widgets;
9.  
10. use yii\web\View ;
11. use yii\widgets\Block ;
12.  
13. class JsBlock extends Block{
14.  
15. /**
16. * @var null
17. */
18. public $key = null;
19. /**
20. * @var int
21. */
22. public $pos = View::POS_END ;
23. /**
24. * Ends recording a block.
25. * This method stops output buffering and saves the rendering result as a named block in the view.
26. */
27. public function run()
28. {
29. $block = ob_get_clean();
30. if ($this->renderInPlace) {
31. throw new \Exception("not implemented yet ! ");
32. // echo $block;
33. }
34. $block = trim($block) ;
35. /*
36. $jsBlockPattern = '|^<script[^>]*>(.+?)</script>$|is';
37. if(preg_match($jsBlockPattern,$block)){
38. $block = preg_replace ( $jsBlockPattern , '${1}' , $block );
39. }
40. */
41. $jsBlockPattern = '|^<script[^>]*>(?P<block_content>.+?)</script>$|is';
42. if(preg_match($jsBlockPattern,$block,$matches)){
43. $block = $matches['block_content'];
44. }
45.  
46. $this->view->registerJs($block, $this->pos,$this->key) ;
47. }
48. }

1. <?php JsBlock::begin() ?>
2. <script>
3. $(function () {
4. jQuery('form#apitool').on('beforeValidate', function (e) {
5. if(驗證規則){
   //不用執行什麼操做,自動會提交
   }else{
   return false;
   }
6. });
7. </script>
8. <?php JsBlock::end() ?>
