所以有幾個問題與您的代碼：

首先，在HTML ID名稱是唯一的，並且您有兩個具有相同ID的元素，即mySidenav。這是你的代碼無法工作的主要原因，因爲它不知道你的目標是哪一個。

要解決你的代碼執行以下操作：

<!-- First video --> 
<div id="first" class="sidenav"> 
    <a href="javascript:void(0)" class="closebtn" onclick="clo.call(this)" data-cls="first">&times;</a> 
    <iframe width="420" height="345" src="https://www.youtube.com/embed/Uks8psEpmB4"></iframe> 
</div> 

<div class="w3-card-4 w3-dark-grey" style="width:50%"> 
    <div class="w3-container w3-center"> 
    <span style="cursor:pointer" onclick="ope.call(this)" data-id="first"> 
     <h3>Friend Request</h3> 
     <img src="img_avatar3.png" alt="Avatar" style="width:80%"> 
     <h5>John Doe</h5> 
    </span> 
    </div> 
</div> 



<!-- Second video --> 
<div id="second" class="sidenav"> 
    <a href="javascript:void(0)" class="closebtn" onclick="clo.call(this)" data-cls="second">&times;</a> 
    <iframe width="420" height="345" src="https://www.youtube.com/embed/1PPDoAKbaNA"></iframe> 
</div> 

<div class="w3-card-4 w3-dark-grey" style="width:50%"> 
    <div class="w3-container w3-center"> 
    <span style="cursor:pointer" onclick="ope.call(this)" data-id="second" > 
     <h3>Friend Request</h3> 
     <img src="img_avatar3.png" alt="Avatar" style="width:80%"> 
     <h5>John Doe</h5> 
     </span> 
    </div> 
    </div>

至於的JavaScript，更改爲：

function ope() { 
    let vidPos = this.getAttribute("data-id"); 
    document.querySelector("#"+vidPos).style.width = "100%"; 
} 

function clo() { 
    let vidPos = this.getAttribute("data-cls"); 
    document.querySelector("#"+vidPos).style.width = "0%"; 
}

你應該注意幾件事情： 1）我改變ope()到ope.call(this)到將窗口對象的上下文更改爲元素。 2）我添加了自定義數據屬性，以幫助區分和定位不同的元素並將它們鏈接到不同的視頻。

您的代碼應該按照您在下面的演示中所預期的那樣工作。

function ope() { 
 
     let vidPos = this.getAttribute("data-id"); 
 
     document.querySelector("#"+vidPos).style.width = "100%"; 
 
} 
 

 
function clo() { 
 
     let vidPos = this.getAttribute("data-cls"); 
 
     document.querySelector("#"+vidPos).style.width = "0%"; 
 
}

body { 
 
     font-family: "Lato", sans-serif; 
 
    } 
 

 
    .sidenav { 
 
     height: 100%; 
 
     width: 0; 
 
     position: fixed; 
 
     z-index: 1; 
 
     top: 0; 
 
     left: 0; 
 
     background-color: #111; 
 
     overflow-x: hidden; 
 
     transition: 0.5s; 
 
     padding-top: 60px; 
 
     text-align:center; 
 
    } 
 

 
    .sidenav a { 
 
     padding: 8px 8px 8px 32px; 
 
     text-decoration: none; 
 
     font-size: 25px; 
 
     color: #818181; 
 
     display: block; 
 
     transition: 0.3s; 
 

 
    } 
 

 
    .sidenav a:hover{ 
 
     color: #f1f1f1; 
 
    } 
 

 
    .sidenav .closebtn { 
 
     position: absolute; 
 
     top: 0; 
 
     right: 25px; 
 
     font-size: 36px; 
 
     margin-left: 50px; 
 
    } 
 

 
    @media screen and (max-height: 450px) { 
 
     .sidenav {padding-top: 15px;} 
 
     .sidenav a {font-size: 18px;}
