我是Yii2的新手,我正在努力通过按Yii2按钮来触发匿名功能.

下面是6个样本,其中前两个是好的.

但这并不是我想要的.

我想知道如何让一个匿名函数工作,比如“Button 3”和“Button 5”的情况.我测试了如何通过Controller进行函数调用,这样可以正常工作,但这不是我想要的.非常感谢你的帮助 – 谢谢！

// This works

$button1 = Button::begin (

[

'label' => 'Button 1',

'options' => [

'class' => 'btn btn-primary',

'onclick' => 'alert("Button 1 clicked");',

],

]);

$button1->run();

// This works

echo Html::button('Button 2', [ 'class' => 'btn btn-primary', 'onclick' => 'alert("Button 2 clicked");' ]);

// This DOES NOT work

echo Html::button('Button 3', [ 'class' => 'btn btn-primary', 'onclick' => 'function ( $event ) { alert("Button 3 clicked"); }' ]);

// This DOES NOT work

$button4 = Button::begin (

[

'label' => 'Button 4',

'options' => [

'class' => 'btn btn-primary',

// 'onclick' => 'alert("Button 1 clicked");',

],

]);

$button4->on('onclick', 'alert("Button 4 clicked");' );

$button4->run();

// This DOES NOT work

$button5 = Button::begin (

[

'label' => 'Button 5',

'options' => [

'class' => 'btn btn-primary',

'onclick' => 'function ( $event ) { alert("Button 5 clicked"); }',

],

]);

$button5->run();

// This DOES NOT work

$button6 = Button::begin (

[

'label' => 'Button 6',

'options' => [

'class' => 'btn btn-primary',

//'onclick' => 'function ( $event ) { alert("Button 4 clicked"); }',

],

]);

$button6->on('onclick', 'function ( $event ) { alert("Button 6 clicked"); }' );

$button6->run();
