Chrome 扩展 - 初始停止后无法重新开始滚动间隔

Question

我的扩展程序需要平滑地滚动到页面底部，这很完美。当 request.doScroll 更改为 false 时，滚动停止正常。但是，如果我尝试重新启用滚动，它不会重新启动。任何想法为什么以及如何实现 stop\start 等功能？

//starts fine for the first time and does not start for the second time
if(request.doScroll){
            chrome.tabs.executeScript(sender.tab.id, {
                code:`
                    let x = 1; //y-axis pixel displacement
                    let y = 1; //delay in milliseconds
                    const t = setInterval(()=> {
                        window.scroll(0, x);
                        x = x + 5; //to increase speed increase increment interval

                        if($(window).scrollTop() + $(window).height() > $(document).height() - 100) {
                            console.log("clearing scrolling interval");
                            clearInterval(t);
                        }

                    }, y);
                    
                    `
            });
            }else{

                chrome.tabs.executeScript(sender.tab.id,
                    {
                        //this stops the scrolling
                        code: "clearInterval(t);"
                    }
                );
            }

尝试用这个改变“if”块：

        code:`
            var t;
            var x;  //y-axis pixel displacement
            (_ => {
            let y = 1; //delay in milliseconds
            t = setInterval(()=> {
                window.scroll(0, x);
                x = (x||1) + 5; //to increase speed increase increment interval

                if($(window).scrollTop() + $(window).height() > $(document).height() - 100) {
                    console.log("clearing scrolling interval");
                    clearInterval(t);
                    x = 1   /* only if you want...*/
                }

            }, y);
            })()`
