Php 基于ajax响应的echo查询

我试图通过AJAX发送一个php表单数据，而无需刷新并以新表单显示数据。我回应了这个问题，但它不起作用。在AJAX响应中，它显示了调用时的getReportAj表单。代码如下所示：

Javascript

getReportAj.php

---

在成功的事件中。。放置console.logdata，然后运行脚本并签入控制台。

您正在尝试将数据发布到get请求更改类型：'post'还请向我们显示getReportAj.phpgetReportAj.php的内容我正在尝试选择数据。.在ajax响应中，它显示我getReportAj.tpl..$\u请求['submit']可能永远不会是真的。它给了我同样的结果。使用console.logdata；…并没有任何区别；。。。检查浏览器中的console in getReportAj.php..为query.echo$selectReport=SELECT*from gradeterm1，其中studentId=.$\u POST['studentId']。在studentmaster.studentId=gradeterm1.studentId上，termValue=1左加入studentmaster；

function getReport()
{
    var dataString = "grNo=" +$(".grNo").val(); 
    $.ajax({
        type: "GET",
        url: "getReportAj.php",
        data: dataString,
        success:function(data)
        {
            $('#result').html(data);
        }
    });
}

<?php

if(!isset($_SESSION['s_activName']) && !isset($_SESSION['s_userType']) || isset($_SESSION['s_userType']) && $_SESSION['s_userType'] == 'Student') {
    $_SESSION['s_urlRedirectDir'] = $_SERVER['REQUEST_URI'];
    header("Location:checkLogin.php");

else {
    if(isset($_REQUEST['submit'])) {
        $selectReport = "SELECT * from gradeterm1
