你好，開發(fā)人員，我想從數(shù)組中的某些對象中獲取隨機數(shù)據(jù)，但是當我想顯示它時，它說對象[對象]，而不是顯示對象中的文本，我嘗試了很多方法，但沒有任何解決方案？非常感謝誰幫助我let bill = [ { name : "Sandra", price : "50$", payment : "visa", cardnumber:"1234 5678 9012 3456" }, { name : "Johnson", price : "200$", payment : "master", cardnumber:"1234 5678 9012 3456" }, ] let get = document.querySelector(".get"); let first = document.querySelector(".first"); let second = document.querySelector(".second"); let third = document.querySelector(".third"); let fourth= document.querySelector(".fourth"); get.addEventListener("click" , ()=> {let text= bill[Math.floor(Math.random()* bill.length)];first.innerHTML = text;second.innerHTML = text;third.innerHTML = text;fourth.innerHTML = text;})body { font-family:"Lato",sans-serif;display:flex;align-items:center;justify-content:center;flex-direction:column;}<body><h1>Get latest invoice</h1><button class="get">Get</button><table > <tr> <th>Name</th> <th>Price</th> <th>Payment</th> <th>Card Number</th> </tr> <tr> <td class="first"></td> <td class="second "></td> <td class="third"></td> <td class="fourth"></td> </tr> </table> </body>
