在调用clearInterval()之后，setInterval()循环仍在运行 [英] setInterval() loop still running after clearInterval() is called

问题描述

我知道setInterval()在每个循环上都会返回一个唯一的ID，并且必须使用该ID调用clearInterval才能杀死该循环.我相信我的代码可以做到这一点，但是循环仍会无限期地运行.

I know that setInterval() returns a unique ID on every loop, and that clearInterval must be called with that ID to kill the loop. I believe my code does this, yet the loop continues to run indefinitely.

var refresh = setInterval(function () {
            $.get(url, function (data) {
                success: {
                    if (data < 5) {
                        data = 5;
                    }
                    var width = data + "%";
                    $("#recalculation-progress-bar").css('width', width);

                    if (data > 99) {
                        clearInterval(refresh);
                        $("#recalculation-message").text("Recalculation complete.");
                    }
                }
            });

        }, 3000);

我已经在debug中检查了这一点，并且明确调用了clearInterval()，并且不会引发任何错误.我做错了什么吗?

I have checked this in debug and clearInterval() is definitely being called and no errors are thrown. Am I doing something obviously wrong?

推荐答案

1 .-

数据默认为字符串 https://api.jquery.com/jquery.get/

data = parseInt(data)

2.-

您添加了第二级同步...您确定此请求的速度快于3000毫秒吗?

You add a second level of sync... Are you sure that this request is faster than 3000ms?

3.-如果数据> 99，则代码有效.

3.- If the data is > 99, the code works.

我担心的是，该请求的时间超过了3秒，并且您仍然收到以前启动的连接.

In my concern, the problem is the request is longer than 3 seconds, and you still receive connections that your previously launched.

    if (data > 99) {
        clearInterval(refresh);
        $("#recalculation-message").text("Recalculation complete.");
    } else {
    //relaunch here the connection and remove the interval
    }
