我正在尝试创建一个通过 jquery 构建的简单“待办事项”应用程序。这个想法是有一个接受字符串的表单输入,让该字符串成为一个变量,然后将其作为新的“项目”添加到“列表”中。问题是,一旦单击提交按钮,这些新项目(应该显示为新的 HTML p 元素)就不会显示出来。
<!DOCTYPE html>
<html>
<head>
<title>To Do</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!-- Bootstrap -->
<link href="css/bootstrap.min.css" rel="stylesheet" media="screen">

<body>
<div class="wrapper">
<div class="main">
<div class="row">

<h1>To Do List</h1>
<form role="form">
<div class="form-group">
<input type="text" class="form-control" id="listInput" placeholder="add items here">
</div>
<div class="button">
<button type="submit" class="btn btn-default">Submit</button>
</div>
</form>
<br/>
<p class="list">
</p>
</div>
</div>
</div>
</div>
</div>
<!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
<script src="//code.jquery.com/jquery.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="js/bootstrap.min.js"></script>
<script src="script.js"></script>
</body>
</html>
查询:
$(document).ready(function(){
$(".button").click(function(){
var add = $('input[name=listInput]').val();
$('.list').append('<p class="item">' + add + '</p>');
});
$(document).on('click','.item', function() {
$(this).remove();
});
});
