我昨天正在尝试通过在线资源学习 PHP。我有一个简单的程序（下面的代码）正在运行。我遇到的最后一个问题是当我单击按钮提交时，整个页面重新加载。

我想寻求您的帮助如何删除该事件。php脚本是否有可能通过不重新加载整个页面来执行？

我在网上读过几篇文章，上面说可以使用 ajax 来完成。不幸的是，我不知道该怎么做，因为我仍然是一个超级初学者。（哈哈）

<form method="POST">
Salary: <input id="salarytext" type="text" name="salary" onkeypress="return isNumberKey(event)"><br>
Membership Type:
<select name="membershiptype">
        <option value="employed">Employed</option>
        <option value="SE">Self Employed</option>
        <option value="VM">Voluntary Member</option>
        <option value="OFW">OFW</option>
</select>

<br/>

<input type="submit" />

</form>

<div class="SSSContributionComputation">

我实际上建议您并不真的需要 PHP 来处理这个应用程序。

PHP 是一种在 Web 服务器上运行的脚本语言。只有当有人从网络服务器请求 php 文件时，PHP 才能执行代码。这可以同步完成（例如当您通过按提交提交表单时）或异步完成（例如当您使用 AJAX 模式时，它使用 javascript 从服务器请求页面）。

当您需要与服务器上的其他资源（如文件或数据库）进行交互时，PHP 非常有用。在上面的代码中，您只有一点逻辑，您希望根据这些逻辑在页面上显示某些内容。

您可以通过将所有逻辑移动到 javascript 中轻松完成此操作。JavaScript 在页面加载后在用户的网络浏览器中运行，因此它可以更改页面而无需将请求发送回服务器。

PHP 可以实现您的目标。但是如果您不想刷新页面，javascript 会更合适。

它看起来像这样（尽管代码也可以变得更短）：

<script>
function processForm(){
    var membershiptype = document.getElementById('membershiptype').options[document.getElementById('membershiptype').selectedIndex].value;
    if(membershiptype == 'employed'){
        employed();
    }else{
        sevmofw();
    }
}
function employed() {
    //get the value from the form
    var sal = document.getElementById('salarytext').value;
    var message =  "Type in your Salary to see the results.";
if (sal <= 1249.99) {message = "Your Employer's (ER) Contribution is P80.70.<br>Your Contribution (EE) is P33.30.<br>Total amount credited to your SSS Account is P114.00";}
