Question

我使用AJAX和jQuery在我的主文档中调用PHP函数，创建了一个测试页面（我的第一次PHP测试）。与其他如何完成的答案不同，我的PHP和HTML都在同一个文件中（phptest.php）。当我点击我的按钮提交表单时（这是一个非常简单的测试 - 我点击一个按钮，发生了一些事情 - 我知道我应该使用javascript）我可以在Firebug的面板中看到帖子已发送，我的页面上没有任何反应，所以我认为这是PHP方面的一个问题。有人可以帮助我，或者给我一些关于为什么我的代码不起作用的指示？在这里。

//   onclick="xmlhttp.open(&quot;GET&quot;,&quot;phptest.php?t=&quot;+ Math.random(), true" <-- Just in case ;)

//jQuery 2 Ajax
$(document).ready(function () {
    var data = {'action': 'callCoinFlip'};
    $("#clickMe1").on('click', function(){

        $.ajax({
            type: "POST",
            url: 'phptest.php',
            dataType: "json",
            data: {'action': 'callCoinFlip'},
            success: function(){
                console.log("pootis");
            }
            //error: function(){
                //console.log("Oh no! There has been a problem.");
            //}
        })
    })
})

Answer 1

而不是

 success: function(){
            console.log("pootis");
        }

尝试：

 success: function(response){
            console.log(response);
        }

您应该看到服务器响应。但是你永远不会对它做任何事情，你应该在页面上加上类似的东西：

 success: function(response){
            $('body').append(response);
        //    console.log(response);
        }

编辑，说你最终会附加你不需要的东西，如脚本等，可能建议将你的coinflip函数放在一个单独的php文件中

Answer 2

或试试这个

    

    $(document).ready(function () {
    $('#clickMe1').click(function(e) {
            $.ajax({
            type:'POST', 
            url: 'phptest.php', 
            data: {'action':'callCoinFlip'}, 

                success: function(response) {
                    $('#result').html(response); 
                }
            });
            return false;        
    });
});

Answer 3

你的代码中犯了两个错误。

在coinFlip()函数中，您添加了一个未定义的变量$recentflip。在上面的行中，您声明了一个变量$recentFlip = rand(0,1);。这意味着$recentflip和$recentFlip不相等。在PHP中，变量区分大小写。查看reference。
执行post请求后，post函数内的错误函数将被调用而不是成功函数，因为在jquery post函数中添加dataType为json表示除了php文件将返回一个json字符串。但php文件将返回纯文本。因此，成功函数不会被调用。要了解有关帖子功能中dataType的更多详细信息，请查看此link。

在解决了这两个问题后，我添加了以下代码。

PHP和jQuery Ajax没有做任何事情
