调用网格动作的函数时请单击 [英] Calling a function on grid action coumn click

问题描述

我在yii中有一个网格，其中有一个带有自定义按钮的操作列，当我单击网格按钮但我遇到错误时，我想调用函数

I have a grid in yii that has an action column with a custom button I would like to call function when the grid button is clicked but i get an error

这是我的代码:

[
        'class' => 'kartik\grid\ActionColumn',
        'template' => '{approve}{new}{reject}',
        'buttons' => [
            'approve' => function ($url, $model) {
                return Html::button('<i class="fa fa-check"></i>', ['value' => Url::to('approvetruck?id='.$model->id),'style' =>'background:none;border:none;','id' => 'approve','onclick'=>'alert('.$model->id.')']);
        },
            'reject' => function ($url, $model) {
                return Html::button('<i class="fa fa-close"></i>',  ['value' => Url::to('checktruck?id='.$model->id."&category=1"),'style' =>'background:none;border:none;', 'onclick'=>'reject('.$model->id.')');
            },

        ],
        'dropdown' => false,
        'vAlign' => 'middle',
        'urlCreator' => function ($action, $model, $key, $index) {
            return '#';
        },


        'deleteOptions' => ['label' => '<i class="glyphicon glyphicon-remove"></i>']
    ]

在网格之后(在同一页面上)

After the grid i have(on the same page)

<?php
$script = <<< JS
 function reject(id) {
   alert(id);

 }

 JS;
$this->registerJs($script);
 ?>

第一个批准执行警报的工作正常，但是调用函数拒绝的拒绝失败. 它返回错误Uncaught ReferenceError: reject is not defined

The first one approve doing the alert works but the reject which calls a function reject fails.. it returns an error of Uncaught ReferenceError: reject is not defined

我该怎么做

推荐答案

似乎您必须使用以下代码注册js

It seems you have to use below code for register js

<?php 

$this->registerJs(' 
    function reject(id) {
    alert(id);
    }', \yii\web\VIEW::POS_HEAD); 
?> 

这将在头部添加js，并且可能会获得您定义的功能

that will add the js in head part and it may get the function which you defined
