ajax获取不到新提交的数据
默认用ajax获取列表
$(document).ready(function() {
  get_pm(1);
});

// 获取信息
function get_pm(page)
{  
  var list = '';
  $.get(MODULE_URL + 'getpm', {"touid":touid, "page":page}, function(response){
  $.each(response.data, function(key, rows) {
  list += rows['content'];
  });
  $(".weibo_list").html(list);
}

// 表单提交函数
function save()
{
  var fromuid = $('#fromuid).val(); 
  var msgto = $('#msgtoid').val();
  var content = $('#content').val();
  var replyid = $('#replyid').val();
  var image = $('#image').val();
  $.post(MODULE_URL + 'dosend', {"fromuid":fromuid, "msgto":msgto,"replyid":replyid, "content":content, "image":image}, function(response){
  if (response.error_code > 0)
  {
  alert(response.msg+'('+response.error_code+')');
  }
  else
  {  
  $('.send_success').show();
  get_pm(1);
  setTimeout(hide_success, 2000);
  }
  }, 'json');
}
 
// 隐藏发送成功div
function hide_success()
{
  $('.send_success').hide();
  // location.reload(); 
}

现在问题是:
我表单提交成功时调用了get_pm(1);应该是重新请求了数据,
表单提交成功了,数据也加到数据库了,但是新的数据无法显示出来,必须刷新下页面才行,不知道是怎么回事?
是ajax哪里用错了吗?

------解决方案--------------------
你有
$(document).ready(function() {
get_pm(1);
});
刷新当然可以,但这就不是ajax了

ajax提交的回调函数中有 get_pm(1);
按理应该有效的,但我怀疑并没有执行到
------解决方案--------------------
是否有主从问题导致的同步慢问题?
Ajax提交评论并接受应答后再次请求刷新还是?

Best Practices for Dependency Injection in PHPBest Practices for Dependency Injection in PHPMay 08, 2025 am 12:21 AM

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
