javascript - json 十六進位被轉換為字串

<code class="javascript">var cmd = ["0x02,0x03,0xB4,0xB4,0x00,0x06","0x00,0x02,0x6E,0x00,0x00,0x05","0x01,0x01,0x00,0x78,0x00,0x05","0x03,0x03,0x82,0x96,0x00,0x05"];</code>

程式碼如上

cmd 是透過PHP 轉換得到的16進位編碼但是JS 取到的時候已經變成了字串
想實現將cmd 變成跟cmd1 一樣的十六進位截圖藍色部分為想要的效果紅色是數據內容

<code>cmd.join().split(',').map(function(v) {return parseInt(v,16);});

JSON.stringify()
括號裡寫變數
