This article mainly gives you a brief introduction on how to dynamically add and delete a div in an element, hoping to get the effect of drawing inferences from one example.

The code example is as follows:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style type="text/css">
#father
{
 width:150px;
 height:150px;
 background-color:red;
}
#father div
{
 width:50px;
 height:50px;
 background-color:green;
 font-size:12px;
}
</style>
<script type="text/javascript" src="/jQuery/jquery-1.8.3.js"></script>
<script type="text/javascript">
$(document).ready(function(){
 $("#father").prepend("<div>脚本之家欢迎您</div>");
})
</script>
</head>
<body>
<div id="father"></div>
</body>
</html>

Copy after login

The above code can add a div to the parent div. Next, we will introduce how to delete a div. Only the core code is given below:

$(document).ready(function(){
 $("#father").prepend("<div>脚本之家欢迎您</div>");
 $("div").remove("#father div");
})

Copy after login

The above code can remove the added div.

Example 2:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
 <html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>Add And Close Div</title> 
<script type="text/javascript教程" > 
$(document).ready(function(){ 
    bindListener();
})
function addimg(){ 
    $("#mdiv").append('<div class="iptdiv" ><input type="file" name="img[]" class="ipt" /><a href="#" name="rmlink">X</a></div>'); 
    
    // 为新元素节点添加事件侦听器
    bindListener();
}
// 用来绑定事件(使用unbind避免重复绑定)
function bindListener(){
    $("a[name=rmlink]").unbind().click(function(){
        $(this).parent().remove(); 
    })
}
</script>
 
</head> 
 <body> 
<form action="" method="post" enctype="multipart/form-data"> 
 <label>请选择上传的图片</label> 
  <a href="javascript:addimg()" id="addImg">增加图片</a> 
  <div class="mdiv" id="mdiv"> 
    <div class="iptdiv" ><input type="file" name="img[]" class="ipt" /><a href="#" name="rmlink">X</a></div> 
   </div> 
  <input type="submit" name="submit" value="上传图片" /> 
 </form> 
 </body> 
 </html>
