SrpingMVC如何接收JS二维数组参数_course

比如我要接收图片中的二维数组，是个复杂对象。  **1. 如果不适用前端Json序列化,后端接收反序列化这种方案的话。应该如何接收**

前端表单提交复合数据类型 到后端java springmvc 变成二维数组 后端不能解析到对象里面 _course

package com.tf56.ps.admin.Bean; import java.util.ArrayList; public class MesModelManageListVO { priv

PHP从表单传递并接收二维数组_course

<div class="post-text" itemprop="text"> <p>I am trying to pass two paired variables, a category and its id for multiple user-created categories from a webform to a file for processing. I want to keep them linked so if someone changes the name field, we are clear what record they are changing as this record is linked to other tables by id.</p> <p>Originally tried two dimensional array...have abandoned that approach. Now trying to use two one dimensional arrays as per suggestion below. I am going with arrays because number of entries on form depends on how many categories user has created. Categories table has id(int), cat(text) and userid(int) fields </p> <p>Difficulty with passing two arrays is how to link the two. If I pass categories as array to receiving page, I can iterate through values to produce sql statements to change each entry. However, I can't figure out how to get correct id which is needed to identify record. If I use a foreach($idarray as $id) inside the foreach(catsarray as $val) I will get multiple ids for each cat. How do I iterate through ids in synch with iterating through cats? Many thanks for help as I have now spent two days on this :(</p> <pre><code>//I am working with $catsarray and $idarray, each with identical indexes, 1,2,3 etc. //How do I get appropriate id for each cat foreach($catsarray as $val) { $sql = "UPDATE cats, set name = $val WHERE (userid ='$userid' AND id=??????)"; mysql_query($sql); } </code></pre> </div>

怎么 post 二维数组_course

$arr=array( array("id"=>1,"name"=>"张三"), array("id"=>2,"name"=>"李四") );

springboot中怎么通过ajax给控制器传递数组？？_course

我在实现该功能的时候发现控制台没有输出语句，页面也没有弹窗，说明控制器应该没有接收到数组； 代码如下： saveId://这个是数组 $.post("all_delete",{"deid":saveI
