Question

我是JS的新秀，所以请耐心等待我。我正在一个带有照片库的网站上工作，当你点击图片时，它会打开一个模态。我已经开发了一个免费模板来实现这一点。

但是，我已经添加了一个“关闭”。图标，但我不知道如何使它工作。你能帮我吗？

以下是代码：

＆＃13;

$(document).ready(function(){        
	$('li img').on('click',function(){
		var src = $(this).attr('src');
		var img = '<img src="' + src + '" class="img-responsive"/>';
		
		//start of new code new code
		var index = $(this).parent('li').index();   

		var html = '';
		html += '<span class="close" style=padding:5px;>X</span>';
		html += img;                
		html += '<div style="height:25px;clear:both;display:block;">';
		html += '<a class="controls next" href="'+ (index+2) + '">pros &raquo;</a>';
		html += '<a class="controls previous" href="' + (index) + '">&laquo; prec</a>';
		html += '</div>';
		
		$('#myModal').modal();
		$('#myModal').on('shown.bs.modal', function(){
			$('#myModal .modal-body').html(html);
			//new code
			$('a.controls').trigger('click');
			$('span.close').trigger('click');
		})
		$('#myModal').on('hidden.bs.modal', function(){
			$('#myModal .modal-body').html('');
		});
				
   });	
})  
         
$(document).on('click', 'a.controls', function(){
	var index = $(this).attr('href');
	var src = $('ul.row li:nth-child('+ index +') img').attr('src');             
	
	$('.modal-body img').attr('src', src);
	
	var newPrevIndex = parseInt(index) - 1; 
	var newNextIndex = parseInt(newPrevIndex) + 2; 
	
	if($(this).hasClass('previous')){               
		$(this).attr('href', newPrevIndex); 
		$('a.next').attr('href', newNextIndex);
	}else{
		$(this).attr('href', newNextIndex); 
		$('a.previous').attr('href', newPrevIndex);
	}
	
	var total = $('ul.row li').length + 1; 
	//hide next button
	if(total === newNextIndex){
		$('a.next').hide();
	}else{
		$('a.next').show()
	}            
	//hide previous button
	if(newPrevIndex === 0){
		$('a.previous').hide();
	}else{
		$('a.previous').show()
	}
	
	
	return false;
});

Answer 1

请使用event委派技术将click处理程序附加到您的close元素。这是因为您通过脚本生成模态的DOM，即它是动态生成的HTML。您可以尝试以下代码而不是代码：

$(document).on("click", ".close", function(){
    // call 'close' method on nearest kendoWindow
    $(this).closest("[data-role=window]").data("kendoWindow").close();
    // the above is equivalent to:
    //$(this).closest(".k-window-content").data("kendoWindow").close();
});

干草使用框架简化你的工作兄弟

<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>

<!-- The Modal -->
<div id="myModal" class="modal">

  <!-- Modal content -->
  <div class="modal-content">
    <span class="close">x</span>
    <p>Some text in the Modal..</p>
  </div>

</div>




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

// Get the button that opens the modal
var btn = document.getElementById("myBtn");

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

// When the user clicks on the button, open the modal 
btn.onclick = function() {
    modal.style.display = "block";
}

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

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
    }
}






<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>

<!-- The Modal -->
<div id="myModal" class="modal">

  <!-- Modal content -->
  <div class="modal-content">
    <span class="close">x</span>
    <p>Some text in the Modal..</p>
  </div>

</div>
Step 2) Add CSS:

Example
/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    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/Box */
.modal-content {
    background-color: #fefefe;
    margin: 15% auto; /* 15% from the top and centered */
    padding: 20px;
    border: 1px solid #888;
    width: 80%; /* Could be more or less, depending on screen size */
}

/* The Close Button */
.close {
    color: #aaa;
    float: right;
    font-size: 28px;
    font-weight: bold;
}

.close:hover,
.close:focus {
    color: black;
    text-decoration: none;
    cursor: pointer;
}
