使用AJAX提交PHP代碼

我是這個PHP編程的初學者，所以希望任何人在更新我的代碼時提交代碼，當按下提交頁面刷新我不想刷新。使用AJAX提交PHP代碼

請有人把ajax提交到這個代碼。

請在此處添加您嘗試的Ajax代碼 – manian

：D hahah我真的試圖讓它花費很多時間 –

我們不會爲您寫信，但我們非常樂意幫助你解決你試圖爲自己做的事 – RiggsFolly

給您的形式例如像id =「形式」的ID

把你的包括/ emailchange.php爲您的表單操作（不需要它）。你需要在你的表單操作和下面的javascript中正確地解決它。

在你的頁面的底部，你需要把這個腳本標籤之間

$(function() { 
"use strict"; 
$("#form").submit(function() { 
    var data = $('#form').serialize(); 
    $.ajax({ 
     url: "includes/emailchange.php", 
     data: data, 
     type: "POST", 
     success: function (msg) { 
      $('#display').html(msg).delay(6000).fadeOut(1000); 
     } 
    }); 
    return false; 
});

}）;

這是爲了讓你開始。處理它並根據需要更改它
