Question

我创建了一个计时器，当用户插入一个安全代码（即569）时，该计时器可以停止。如何在插入代码时停止计时器，因为现在它只显示＆＃34;祝贺，任务完成！＆＃34;

＆＃13;

function startTimer(duration, display) {
		var timer = duration, minutes, seconds;
		setInterval(function () {
			minutes = parseInt(timer / 60, 10)
			seconds = parseInt(timer % 60, 10);

			minutes = minutes < 10 ? "0" + minutes : minutes;
			seconds = seconds < 10 ? "0" + seconds : seconds;

			display.textContent = minutes + ":" + seconds;

			if (--timer < 0) {
				document.getElementById("text").innerHTML = "You're dead";
			}
		}, 1000);
	}

		window.onload = function () {
    		var Minutes = 60 * 0.5,
        		display = document.querySelector('#time');
    		startTimer(Minutes, display);
		};
        
        function StopFunction() {
			var code;
			var rightcode=569;
			code = document.getElementById("icode").value;
			text = (code==rightcode) ? "Congratulation, mission complete!":"Sorry, wrong code, try again!";
			if(code==rightcode){
				display = document.getElementById("time").innerHTML = "Stop timer";}
			document.getElementById("text2").innerHTML =text;
		}

＆＃13;

.btn {
    border: none;
    color: white;
    padding: 14px 28px;
    font-size: 16px;
    cursor: pointer;
}

.success {background-color: #4CAF50;} /* Green */
.success:hover {background-color: #46a049;}

＆＃13;

<div id="text">You have <span id="time"></span> minutes left!</div>

<p id="text2"></p>
<br>
<p>Enter the code:</p>
<input id="icode"/>
<button class="btn success" onclick="StopFunction()">Check code</button>

以下代码应该适合您

var interval;

function startTimer(duration, display) {
        var timer = duration, minutes, seconds;
        interval=setInterval(function () {
            minutes = parseInt(timer / 60, 10)
            seconds = parseInt(timer % 60, 10);

            minutes = minutes < 10 ? "0" + minutes : minutes;
            seconds = seconds < 10 ? "0" + seconds : seconds;

            display.textContent = minutes + ":" + seconds;

            if (--timer < 0) {
                document.getElementById("text").innerHTML = "You're dead";
            }
        }, 1000);
    }

        window.onload = function () {
            var Minutes = 60 * 0.5,
                display = document.querySelector('#time');
            startTimer(Minutes, display);
        };

        function StopFunction() {
            var code;
            var rightcode=569;
            code = document.getElementById("icode").value;
            text = (code==rightcode) ? "Congratulation, mission complete!":"Sorry, wrong code, try again!";
            if(code==rightcode){
                display = document.getElementById("time").innerHTML = "Stop timer";}
            document.getElementById("text2").innerHTML =text;
clearInterval(interval);
        }
