    <ul id='msglist'><volist name="res" id='vo2'><li class="clearfix" id="{$vo2.WithUid}" style="border:1px solid #000"><a class="delCurSx" style="display:none">X</a><div class="title"><h3 id="nbsp-vo-ToName"> {$vo2.ToName}</h3><p>{$vo2.AddTime}</p></div><div class="detail"><div class="sxDetailCon">{$vo2.Msg}</div>              </div></li></volist></ul>

    Copy after login


    为什么实现不出来效果呢?



    你加载jquery了吗

    像我上面给你的例子一样,把你的js代码放到
    $(document).ready(function(){ ... })这个里面来!

    这个是让你页面运行完了再执行js,你一开始就执行js,页面中还没有所写那些元素呢,完整代码如下

    1

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"type="text/javascript"></script><script>$(document).ready(function(){    $('#msglist li').mouseover(function(){      $(this).children("a").css("display","block");   });         $('#msglist li').mouseout(function(){       $(this).children('a').css("display","none");    }); })</script><ul id='msglist'>    <volist name="res" id='vo2'>      <li class="clearfix" id="{$vo2.WithUid}" style="border:1px solid #000">           <a class="delCurSx" style="display:none">X</a>          <div class="title">               <h3 id="vo-ToName">{$vo2.ToName}</h3>               <p>{$vo2.AddTime}</p>           </div>            <div class="detail">              <div class="sxDetailCon">{$vo2.Msg}</div>                       </div>        </li> </volist></ul>

  • Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

    JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

    The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
