jquery

问题 I've been making my first website - a single page site with different sections containing content. I've created a nice looking navbar and have been scouring the internet to try and find a way to add functionality to it. Here is the markup of the navbar: <div class="nav"> <div class="container"> <div class="title"> <h3>Stewart Ehoff</h3> </div> <a href="#" class="logo-icon"> <img src="images/shield.svg"> </a> <ul class="menu"> <li><a href="#home">Home</a></li> <li><a href="#about">About</a><

问题 I want to have multiple plus/minus counters on my page. I have one working counter but want to make it generic so that multiple counters can have a different initial value and increase and decrease as clicked. $('.counter-btn').click(function(e) { e.preventDefault(); var $btn = $(this); $('.output').html(function(i, val) { val = val * 1 + $btn.data('inc'); return (val <= 0 ? '' : '+') + val; }); }); <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

问题 I'm new to jQuery and am trying to create jQuery UI buttons dynamically and them to a list. I can create one list item but no more are appended after it. What am I doing wrong? $('#buttonList').append('<li><button>'+ username + '</button>') .button() .data('type', userType) .click(function(e) { alert($(this).data('type')); }) .append('<button>Edit</button></li>'); <div> <ul id="buttonList"> </ul> </div> This only creates one list item with two buttons (although the second button seems to be
