我有一些圖像和數據顯示爲使用Jquery工具疊加。如何關閉覆蓋圖並清除覆蓋圖中的數據?

我必須點擊兩次才能打開它。當我關閉覆蓋層並再次打開時,它會顯示第一個和第二個圖像和數據。

/**close overlay function**/ 

    function closeNav(id) { 

    document.getElementById("myNav").style.height = "0%"; 

} 

我希望當我點擊第二,第三.....時候,它只是顯示它的圖像和數據,不能顯示其他的圖像和data.How我能解決這個問題?

謝謝。

代碼:

var APIurl = "http://120.96.86.139/api/Meet_ViewPoint/GET/1"; 
 

 
    $.get(
 
     APIurl,

      var i = 0; 
 
      $.each(data, function(key, value) { 
 
       console.log(key + ":" + value) 
 
       var JSONdata = JSON.stringify(data); 
 
       var NumOfJData = JSONdata.length; 
 

 
       $("#main").append("<div class='box' href='' id='boxmsg" + i + "' onclick='openNav(" + value.View_no + ")'> " +

innerHTML = ''

$.empty()將清空的元素。

function closeNav(id) { 

    var myNav = document.getElementById("myNav"); 

    myNav.style.height = "0%"; 
    myNav.innerHTML = ''; 

} 

.overlay { 
 
    height: 0%; 
 
    width: 100%; 
 
    position: fixed; 
 
    z-index: 1; 
 
    top: 0; 
 
    left: 0; 
 
    background-color: rgb(0, 0, 0); 
 
    background-color: rgba(0, 0, 0, 0.9); 
 
    overflow-y: hidden; 
 
    transition: 0.5s; 
 
} 
 

 
.overlay-content { 
 
    max-width: 1200px; 
 
    margin: 0 auto; 
 
    margin-top: 8%; 
 
    position: relative; 
 
    width: 100%; 
 
} 
 

 
.overlay a { 
 
    margin-top: 2%; 
 
    padding: 8px; 
 
    text-decoration: none; 
 
    font-size: 28px; 
 
    color: #818181; 
 
    display: block; 
 
    transition: 0.3s; 
 
} 
 

 
.overlay a:hover, 
 
.overlay a:focus { 
 
    color: #f1f1f1; 
 
} 
 

 
.overlay .closebtn { 
 
    position: absolute; 
 
    top: 20px; 
 
    right: 45px; 
 
    font-size: 60px; 
 
} 
 

 
@media screen and (max-height: 450px) { 
 
    .overlay { 
 
    overflow-y: auto; 
 
    } 
 
    .overlay a { 
 
    font-size: 20px 
 
    } 
 
    .overlay .closebtn {
