如何使用 ajax 将 GET 值和可用的 php 发送到另一个页面？

Question

首先我访问

www.mysite.com/index.php?order_by=id asc

我想将$name 和$_GET[order_by] 发送到autoload_process.php，我该怎么做？

$results = $mysqli->query("SELECT COUNT(*) as t_records FROM product_details");
$total_records = $results->fetch_object();
$total_groups = ceil($total_records->t_records/$items_per_group);
$results->close(); 
?>

<script type="text/javascript">
$(document).ready(function() {
    var track_load = 0; //total loaded record group(s)
    var loading  = false; //to prevents multipal ajax loads
    var total_groups = <?php echo $total_groups; ?>; //total record group(s)

    $('#results').load("autoload_process.php", {'group_no':track_load}, function() {track_load++;}); //load first group

    $(window).scroll(function() { //detect page scroll

        if($(window).scrollTop() + $(window).height() == $(document).height())  //user scrolled to bottom of the page?
        {

            if(track_load <= total_groups && loading==false) //there's more data to load
            {
                loading = true; //prevent further ajax loading
                $('.animation_image').show(); //show loading image

                //load data from the server using a HTTP POST request
                $.post('autoload_process.php',{'group_no': track_load}, function(data){

                    $("#results").append(data); //append received data into the element

                    //hide loading image
                    $('.animation_image').hide(); //hide loading image once data is received

                    track_load++; //loaded group increment
                    loading = false; 

                }).fail(function(xhr, ajaxOptions, thrownError) { //any errors?

                    alert(thrownError); //alert with HTTP error
                    $('.animation_image').hide(); //hide loading image

Answer 1

先把url参数值保存到这样的隐藏输入框

<input type="hidden" id="orderby" value="<?php echo $_GET['orderby']; ?>"/>

和像这样的会话变量

<input type="hidden" id="name" value="<?php echo $_SESSION['Username']; ?>"/>

然后像这样在 $.POST 中传递值

var orderby = $("#orderby").val();

var name = $("#name").val();

$.post('autoload_process.php',{'group_no': track_load, 'order_by':orderby, 'name':name} , function(data){

Answer 2

$.post 的第二个参数是“数据”。您可以将变量作为对象发送。

例如：{ 'group_no': track_load, name: 'John Smith', order_by: 'id asc' }
