php文件中的jquery

Jun 23, 2016 pm 01:41 PM

php中可以包含jquery语句吗?假设a.php 中有  而且引入了jq.js
b.php中有<script> <br /> $(window).on('scroll',function(){ <br /> alert('123'); <br /> }) <br /> a.php中为什么没有 alert? 只是举个例子 新手一个 <br /> <p> </script>


回复讨论(解决方案)

举例子就请举个可供测试的例子
你用文字描述代码,有谁知道你的代码是否正确呢?
你绑定了滚动条事件,但你的页面就一定会出现滚动条吗?

感谢楼上指正 现贴代码如下
a.php
require_once('b.php');
?>
<script> <br /> <script type="text/javascript" src="c.js"></script>

//为了出现滚动条






b.php
<script> <br /> $(window).on('scroll',function(){ <br /> alert ('123'); <br /> }) <br /> <br /> }); <br /> </script>
c.js
$(window).on('scroll',function(){
alert ('abc');
})

我自己测试的结果是 b.php中的jq代码没有效果  c.js起作用alert abc  不明白是什么道理 应该在b.php中怎么修改

b.php
<script> <br /> $(window).on('scroll',function(){ <br /> alert ('123'); <br /> }) <br /> <br /> }); 这个多了,删除就可以了。 <br /> </script>

感谢楼上回答  但还是不行啊

你的b.php里面的js是在引用jquery前就使用了jq的方法,所以失效,而c.js是在引用了jquery后,所以可以成功弹出,还有2楼的大括号和中括号确实多余的
a.php

<script type="text/javascript" src="js/jquery-2.1.1.min.js" ><?phprequire_once('b.php');?><script type="text/javascript" src="c.js"></script><style type="text/css">.show{width:150px;height:150px;background-color:#f90;}</style><div class="show"></div>//为了出现滚动条<div class="show"></div><div id="show"></div><div class="show"></div><div class="show"></div><div class="show"></div>
Copy after login

这样应该可以了

<script type="text/javascript">$(function() {  $(window).on('scroll',function(){    alert ('123');  })});</script>
Copy after login
这样写,就与加载次序无关了

所以 #2 不是多了 });
而是少了 $(function() {

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.
