為什么我的模態 window 在單擊后沒有關閉？
[英]Why is my modal window not closing after a click?
問題描述
我的 HTML 上有兩個元素。 在每個標簽中都有一個問號圖標。單擊問號會觸發模態 window。 這是我的 html 代碼看起來像
<form>
<div class="form-group">
<label class="control-label col-md-4 col-lg-3 required" for="offer_title" id="ThemaLbl">

第一個盒子工作正常。 但是，由於某種原因，第二個框在單擊“確定”按鈕后沒有關閉。 My.css 看起來像這樣：
/* The Modal (background) */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 999; /* Sit on top */
padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}
/* Modal Content */
.modal-content {
background-color: #fefefe;
margin: auto;
padding: 20px;
border: 1px solid #888;
width: 80%;
}
/* The Close Button */
.close {
color: #aaaaaa;
float: right;
font-size: 28px;
font-weight: bold;
}
.close:hover,
.close:focus {
color: #000;
text-decoration: none;
cursor: pointer;
}
.modalheader{
margin: -17px -17px 15px;
padding: 10px 15px;
background-color: #f2fcde;
border-bottom: 1px solid silver;
font-weight: 600;
line-height: 40px;
display: -ms-flexbox !important;
font-family: inherit;
font-size: 7;
}
這是我的js：
function myFunction(modalElem){
// Get the modal
var modal = document.getElementById(modalElem);
// Get the <span> element that closes the modal
var span = document.getElementById("commentOK");
modal.style.display = "block";
// When the user clicks on <span> (OK), close the modal
span.onclick = function() {
modal.style.display = "none";
}
我嘗試將模態 windows 的代碼放在 html 文件底部靠近主體的“表單”之外，但這沒有幫助。 我不是一個經驗豐富的 html 程序員，無論錯誤是什么，我都找不到它。 我怎樣才能解決這個問題？
2 個解決方案
解決方案1

var modal = document.getElementById(ok);
我認為問題是 getElementById 里面的 ok 必須是一個字符串，試試：
var modal = document.getElementById('ok');

當您在兩個模式中為兩個按鈕使用相同的 id 時，問題就出現了。 document.getElementById在整個文檔中搜索具有該 id 的唯一元素，結果它只返回 HTML 中具有該 id 的第一個元素。
建議在 HTML 元素中使用唯一 id
如果 id 值不是空字符串，則它在文檔中必須是唯一的。
檢查這個https://developer.mozilla.org/en-US/docs/Web/API/Element/id
但是，如果您想保留重復的 id，則應該從模態 div 元素中的子元素中查找該元素。 您可以使用 querySelector 來執行此操作並查詢 id 屬性
查詢選擇器https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector
屬性選擇器https://developer.mozilla.org/en-US/docs/Web/CSS/Attribute_selectors
這里的工作示例：
function myFunction(ok) { // Get the modal var modal = document.getElementById(ok); // Get the <span> element that closes the modal var span = modal.querySelector("[id=commentOK]"); modal.style.display = "block"; // When the user clicks on <span> (OK), close the modal span.onclick = function() { modal.style.display = "none"; } }
/* The Modal (background) */.modal { display: none; /* Hidden by default */ position: fixed; /* Stay in place */ z-index: 999; /* Sit on top */ padding-top: 100px; /* Location of the box */ left: 0; top: 0; width: 100%; /* Full width */ height: 100%; /* Full height */ overflow: auto; /* Enable scroll if needed */ background-color: rgb(0, 0, 0); /* Fallback color */ background-color: rgba(0, 0, 0, 0.4); /* Black w/ opacity */ } /* Modal Content */.modal-content { background-color: #fefefe; margin: auto; padding: 20px; border: 1px solid #888; width: 80%; } /* The Close Button */.close { color: #aaaaaa; float: right; font-size: 28px; font-weight: bold; }.close:hover, .close:focus { color: #000; text-decoration: none; cursor: pointer; }.modalheader { margin: -17px -17px 15px; padding: 10px 15px; background-color: #f2fcde; border-bottom: 1px solid silver; font-weight: 600; line-height: 40px; display: -ms-flexbox;important: font-family; inherit: font-size; 7; }
