Wie bekomme ich Checkbox-Wert und speichere in einem Array

Question

In meinem Projekt möchte ich Checkbox Wert in Array zu instorieren.

Hier ist mein Code:

$('#fpdId').click(function(){ 
    var files = new Array(); 

    //xzyId is table id. 
    $('#xzyId tbody tr input:checkbox').each(function() { 
     if (this.checked) { 
     files.push(this.value); 
     } 
    }); 

    console.log(files); 
}); 

    <input type="button" id="fpdId" value="filePack"> 

Meine HTML-Tabelle hat drei Zeilen und jede Zeile hat drei tds

Hier Codetabelle:

<table border=1px class="xzy" id="xzyId" style="width:100%"> 
     <colgroup> 
      <col style="width:10%"> 
      <col style="width:80%"> 
      <col style="width:10%"> 
     </colgroup> 
     <tbody> 
     <tr> 
      <td ><input type="checkbox" value="x" >1</td> 
      <td >Stack</td> 
      <td >John</td> 
     </tr> 
     <tr> 
      <td ><input type="checkbox" value="y" >2</td> 
      <td >Stack</td> 
      <td >Sansa</td> 
     </tr> 
     <tr> 
      <td ><input type="checkbox" value="z" >3</td> 
      <td >Stack</td> 
      <td >Aya</td> 
     </tr> 
     </tbody> 
     </table> 

Aber Pech, das Array leer, was ist los?

Es wird Ihnen helfen

Ich habe geändert.

if ($(this).is(':checked')) { 
    } 

$("document").ready(function(){ 
 
$('#fpdId').click(function(){ 
 
    var files = new Array(); 
 

 
    //xzyId is table id. 
 
    $('#xzyId tbody tr input:checkbox').each(function() { 
 
     if ($(this).is(':checked')) { 
 
     files.push(this.value); 
 
     } 
 
    }); 
 

 
    console.log(files); 
 
}); 
 

 
})
