我應該寫一些代碼htmljavascript或其他通過點擊圖像打開一個彈出窗口。 我已經看到window.open()方法,但這不是我正在尋找的。 準確地說,我想打開一個像Twitter這樣的圖像彈出窗口:遮蓋背景並顯示在屏幕中間放大的圖像。HTML - JS如何通過點擊打開圖像彈出圖像?

有什麼建議嗎?

您可以使用Bootstrap,否則,製作絕對/固定位置居中的DIV。點擊獲取圖像的URL,並將其放入新的DIV中的img標籤中。最後添加淡入/淡出到效果的新DIV。

可以使用lightbox

它的使用非常簡單。在HTML文件中的腳本標籤和CSS樣式表,然後簡單地使用:

<a class="example-image-link" href="images/image-1.jpg" data-lightbox="example-1"><img class="example-image" src="images/thumb-1.jpg" alt="Girl looking out people on beach"></a>

// Get the modal 
 
var modal = document.getElementById('myModal'); 
 

 
// Get the image and insert it inside the modal - use its "alt" text as a caption 
 
var img = document.getElementById('myImg'); 
 
var modalImg = document.getElementById("img01"); 
 
var captionText = document.getElementById("caption"); 
 
img.onclick = function(){ 
 
    modal.style.display = "block"; 
 
    modalImg.src = this.src; 
 
    captionText.innerHTML = this.alt; 
 
} 
 

 
// Get the <span> element that closes the modal 
 
var span = document.getElementsByClassName("close")[0]; 
 

 
// When the user clicks on <span> (x), close the modal 
 
span.onclick = function() { 
 
    modal.style.display = "none";
