div内span标签的onclick事件

Question

I'm trying to make a button that opens a image on my webpage and then when you press the x in the corner it closes. I got the image to open, but the close button isn't working and I don't know why.

 var modal = document.getElementById("myModal"); var img = document.getElementById("myImg"); var modalImg = document.getElementById("img01"); img.onclick = function() { modal.style.display = "block"; modalImg.src = "image link"; } function close(i) { document.getElementById(i).style.display = "none"; }

 <div class="sidebar"> <div class="schedule"> <button id="myImg"> <h4><span class="fa fa-caret-right"></span> Schedule</h4> <div id="myModal" class="modal"> <span class="close" style="z-index: 999;" onclick="close('myModal')">&times;</span> <img class="modal-content" id="img01" /> </div> </button> </div> </div>

You have a button inside a modal which is inside a button. That is a problem since the outer button prevents the inner button from working. Lets break those out a bit, and use a relative reference to close the modal.

First separate the modal from the button.

 var modal = document.getElementById("myModal"); var img = document.getElementById("myImg"); var modalImg = document.getElementById("img01"); img.onclick = function() { modal.style.display = "block"; modalImg.src = "https://picsum.photos/200/300"; } function closeModal(el) { el.closest('.modal').style.display = "none"; }

 #myModal { display: none; } .close { display: inline-block; padding: 5px; cursor: pointer; }

 <div id="myModal" class="modal"> <span class="close" style="z-index: 999;" onclick="closeModal(this)">&times;</span> <img class="modal-content" id="img01" /> </div> <div class="sidebar"> <div class="schedule"> <button id="myImg"> <h4><span class="fa fa-caret-right"></span> Schedule</h4></button> </div> </div>

Using relative references like that are handy when you have more than one element that can call them. Additionally it frees you from having to call an ID.
