alex-bond / yii2-thumbler＆＃34; Class＆＃39; Thumbler＆＃39;找不到＆＃34;

Question

如何使用此小部件alex-bond / yii2-thumbler Link。我试过这样的事情

$path = \Yii::$app->thumbler->resize
        ('49_long.jpg',500,500, $method = Thumbler::METHOD_CROP_CENTER, $backgroundColor = 'ffffff', $callExceptionOnError = true);

如上所述，但我收到了一个错误＆＃34; Class＆＃39; Thumbler＆＃39;找不到＆＃34;。我怎么用呢？

尝试添加为代码添加正确的引用

function getInfo(){
   if(request.readyState==4){  
        var val=request.responseText;  
        document.getElementById('dsp').innerHTML=val;  
        document.getElementById('rd').style.display = 'none';
        document.getElementById('fr').style.display = 'none';
   }  
}
