关于jquery的问题,按钮点击事件

Jun 23, 2016 pm 01:42 PM

有A、B两个页面
A页面有多个“修改”按钮,每个按钮有样式class="editbtn",点击ajax到B页面,如下代码

$(".editbtn").click(function(){		var url="b.php";		var params = $('form').serialize();		$.ajax({			url: url,			type: 'post',			dataType:'json',			data: params,			success: function (data){				$("#div1").html(data.html);				$("#div2").html(data.script);			}		});	});
Copy after login

B页面
$data=array(	'html'=>$html,	'script'=>$script);echo json_encode($data);
Copy after login

B页面也会返回N条包含class="editbtn"的“修改”按钮,返回的这些按钮点击就无法完成$(".editbtn").click了,请问是什么原因呢?
之所以B页面有'script'=>$script,就是因为无法完成$(".editbtn").click事件,我又在B页面加了上面那段jquery,把它又弄到$("#div2").html,这样就可以运行,但是这样我感觉效率不好,好像如果点击了很多次就重复了很多次相同的代码,大神们觉得这样好吗?应该不好吧?

把 $(".editbtn").click(function(){
改为 $(document).on('click', ".editbtn", function(){
就可以了

把 $(".editbtn").click(function(){
改为 $(document).on('click', ".editbtn", function(){
就可以了


谢谢解答哈。
我之前是放在$(document).ready里面的,按照你说的我不管是放在这个内还是外提示:
TypeError: $(...).on is not a function

绑定事件改成
$('.clickme').live('click', function() {
  alert("Live handler called."); 
});
live:给所有匹配的元素附加一个事件处理函数,即使这个元素是以后再添加进来的也有效

把 $(".editbtn").click(function(){
改为 $(document).on('click', ".editbtn", function(){
就可以了


换了jquery版本可以了,之前用的jquery-1.6.2.min,改为jquery-1.8.3.min,谢谢,好多问题都是你回答解决的。

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,

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

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.
