Question

创建函数可增加每次有人单击按钮时称为clicks的会话值，php可以正常工作，但无法通过AJAX调用它。

jQuery：

$("button").click(function() {
    $.ajax({
        url: 'resources/ajax/addclick.php',
        success: function(output) {
            alert(output);
        }
    });
});

php：addclicks.php

<?php 
require_once("../config.php");

function click(){
    $_SESSION['clicks'] ++;
}
?>

php：config.php

session_id();
session_start();

$id = session_id();

if (!isset($_SESSION['started'])) {
    date_default_timezone_set("Asia/Tokyo");
    $_SESSION['started'] = date("h:i:s a");
    $_SESSION['date'] = date("Y/m/d");
}

if (!isset($_SESSION['clicks'])) {
    $_SESSION['clicks'] = 0;
}

html按钮：

<form class="button" method="post">
  <button class="button" id="button" type="submit">Click 
   me</button>
  </form>

Answer 1

$("button").click(function(){   
  $.ajax({
  method: "POST",
  url: "addclick.php",
  data: { add: 1 }
})
  .done(function( msg ) {
    alert( msg );
  });
});

您的php最像这样

<?php
$_SESSION['clicks'] = $_SESSION['clicks'] + $_POST['add'];

echo $_SESSION['clicks'];
?>

您的html不需要表单标签，至少您想阻止提交

<button class="button" id="button" type="submit">Click 
   me</button>

jQuery onclick函数通过AJAX在PHP中调用函数
