Ajax Codeigniter变量问题

发布于 2024-10-15 08:01:00 字数 1057 浏览 2 评论 0原文

我有一个问题，我不知道我是否将其发布在论坛的正确位置。我正在尝试使用 Ajax 制作一个表单来通过 Ajax 计算我的点击次数。但问题是，每次我点击一次，我总是收到的点击次数为 1。

这是一段解释的代码：

在视图中的 JavaScript

$("#click").click(function(){    
            $.ajax({
                type: "POST",
                url: bseUrl+"counter/incCount",
                data: click,
                success: function(html){
                    alert(html);
                }
            });
        });

警报（html）应该显示总数来自服务器的点击；

计数器控制器

class Counter extends CI_Controller {

    //put your code here
    var $numClick;

    public function __construct() {
        parent::__construct();
        $this->numClick= 0;
    }

    public function Counter() {
        parent::__construct();
$this->numClick= 0;
    }

    public function incCount() {
        echo $this->numClick++;
    }

public function index() {
        //loadView
    }
}

但是每次点击时我收到的点击次数总是为 1。为什么我每次都会丢失可变内容？似乎每次我进行 Ajax 调用时我都会启动该变量。

你们能帮我吗？

原文

I have a question, and I don't know if I'm posting it on the right place of the forum.
I'm trying to do a form with Ajax to count my clicks through Ajax. But the problem is that every time I do a click I always receive the number of clicks as 1.

Here's a piece of the code explained:

In JavaScript from the View

$("#click").click(function(){    
            $.ajax({
                type: "POST",
                url: bseUrl+"counter/incCount",
                data: click,
                success: function(html){
                    alert(html);
                }
            });
        });

The alert(html) should show the total clicks from the server;

counter controller

class Counter extends CI_Controller {

    //put your code here
    var $numClick;

    public function __construct() {
        parent::__construct();
        $this->numClick= 0;
    }

    public function Counter() {
        parent::__construct();
$this->numClick= 0;
    }

    public function incCount() {
        echo $this->numClick++;
    }

public function index() {
        //loadView
    }
}

But every time I click I'm always receiving the number of clicks as 1.
Why am I losing the variable content every time? it seems that every time I do a Ajax call I'm starting the variable.

Can you guys help me?

每次调用点击处理函数时都会重新初始化计数器 - 为什么？
尝试这样做：

//init counter somewhere
var num_clicks= 0;
//increase counter and send request
$("#click").click(function(){
            num_clicks++;
            var click= "numberClick="+num_clicks;
            $.ajax({
                type: "POST",
                url: bseUrl+"counter/incCount",
                data: click,
                success: function(html){
                    alert(html);
                }
            });
        });

You are re-initializing the counter every time you call click handling function - why?
try doing it this way:

//init counter somewhere
var num_clicks= 0;
//increase counter and send request
$("#click").click(function(){
            num_clicks++;
            var click= "numberClick="+num_clicks;
            $.ajax({
                type: "POST",
                url: bseUrl+"counter/incCount",
                data: click,
                success: function(html){
                    alert(html);
                }
            });
        });
