jQuery的ajax发布 [英] ajax post with jQuery

问题描述

单击元素时，是否可以使用POST方法提交ID?我认为jQuery具有内置的AJAX功能...

Is it possible to submit with POST method an ID when an element is clicked? I think jQuery has a built in AJAX fanction...

<span id="submitThisID"></span>

推荐答案

$('#submitThisId').click(function() {
  $.post("postTo.php", { id: $(this).attr('id') }, function(response) {
    alert(response);
  });
});

这会将您的ID发布到postTo.php，并且可以使用以下方法进行检索:$id = $_POST['id'];

This will post your id to postTo.php and can be retrieved using: $id = $_POST['id'];

postTo.php文件返回的所有内容都会显示在屏幕上(响应).

Whatever the postTo.php file returns will be alerted to the screen (response).

编辑:要提交到同一页面并执行一些服务器端操作(数据库查询等)，您只需在页面顶部放置类似于以下代码的内容:

To submit to the same page and do some server-side actions (db query, etc) you would only need to put something similar to the following code at the top of your page:

<?php 
  if (isset($_POST['id'])) {
    $id = $_POST['id'];
    // Perform some db queries, etc here
    $response = 'Format a response here'; // Format a response

    // This will return your formatted response to the $.post() call in jQuery 
    return print_r($response);
  } 
?>

当响应"(文本，html等)返回给jQuery时，您可以使用简单的jQuery在必要时将其插入到页面中，并更改页面的外观.

When that "response" (text, html, etc) is returned to jQuery, you can use simple jQuery to insert it into the page where necessary and change the look of the page.
