Javascript 如何在Java脚本中停止实时

我想停止java脚本中的实时性。我该怎么做呢。这是我的实时java脚本源代码

        setInterval(function(){
        var d = new Date()
        var h = d.getHours()
        var m = d.getMinutes()
        var s = d.getSeconds()
        h = (h < 10) ? ("0" + h) : h;
        m = (m < 10) ? ("0" + m) : m;
        s = (s < 10) ? ("0" + s) : s;
        document.getElementById("time").value = h +":"+m+":"+s
}, 1000)


document.getElementById("time").setAttribute("disabled","disabled")
document.getElementById("time").clearInterval(value)

使用clearInterval函数

WindowOrWorkerGlobalScope mixin的clearInterval方法取消一个定时重复操作，该操作以前是通过调用setInterval建立的

如果此字段为必填字段，我们如何单击“提交”按钮。这是一个错误

var interval = setInterval(function(){
        var d = new Date()
        var h = d.getHours()
        var m = d.getMinutes()
        var s = d.getSeconds()
        h = (h < 10) ? ("0" + h) : h;
        m = (m < 10) ? ("0" + m) : m;
        s = (s < 10) ? ("0" + s) : s;
        document.getElementById("time").value = h +":"+m+":"+s
}, 1000)

// this will cancel the interval when you want it to
clearInterval(interval);
