但是我无法使用此脚本修改函数上的计数器变量值:

but I unable to modify the counter variable value on the function with this script:

// ==UserScript==
// @name       My Fancy New Userscript
// @namespace  http://use.i.E.your.homepage/
// @version    0.1
// @description  enter something useful
// @match      https://welcome.telkomhotspot.info/telkomhs/freemax/
// @copyright  2012+, You
// ==/UserScript==

unsafeWindow.counter = 1;

这是我要更改的功能:

function startTimer(){
var counter = 20;
var wait = 0;
var displayCounter = true;
var startCounting = false;
$("#timerTransition").html(getLoadingCounter())
.everyTime(1000,function(i){
    if(wait==0){
        if(displayCounter){
            $("#loadingCounter").fadeOut(500,function(){
                $("#timerTransition").html(getTimerContainer(counter));
                $("#timerContainer").fadeIn(500,function(){
                    startCounting = true;
                });
            });
        }
        displayCounter = false;
        if(startCounting){
            counter = counter - 1;
            $("#counter").html(counter);
            if(counter == 0) {

                if(foundCookies){
                    $("#timerTransition").stopTime().html(getAuthCookiesLogin());
                }
                else{
                    $("#timerTransition").stopTime().html(getAuthButton());
                    $("#authBtnContainer").fadeIn(0).click(function(){
                        $(this).fadeOut(0);
                        closeAds();
                        openAuthForm();
                    });
                }
            }
        }
    }
    else{
        wait = wait-1;
    }
});
}

感谢您的帮助,我已经在google上搜索了,但仍然无法修改变量.

Thanks for helping, I already searching on google but still I can't modify the variable.

推荐答案

counter是函数内的局部变量.除非您可以修改函数以使用全局变量,否则将无法更改其值.如果您无权访问该代码,则可以尝试使用自己的实现替换整个startTimer函数.我无法从您的示例中看出来,但是如果它是全局的,则只能替换startTimer.

counter is a local variable within a function. You will not be able to change its value unless you can modify the function to use a global variable. If you do not have access to the code, you could try replacing the entire startTimer function with your own implementation. I can not tell from your example, but you can only replace startTimer if it is a global.
