Javascript 代码在函数内部时不运行

Question

我正在用 html 和 javascript 制作游戏，并使用“控制台”，我使用 IF 语句来允许用户在游戏中导航。但是，他们似乎停止了工作。它们允许用户在游戏中移动。为什么 IF 语句没有运行以及如何解决这个问题？

function runcmd(){
	var user = document.getElementById('code').value;
	if(user == 'clear'){
		l1.innerHTML = '';
		l2.innerHTML = '';
		l3.innerHTML = '';
		l4.innerHTML = '';
		l5.innerHTML = '';
		l6.innerHTML = '';
		l7.innerHTML = '';
		l8.innerHTML = '';
		l9.innerHTML = '';
		l10.innerHTML = '';
	};
	if(user == 'connect'){
		var user = document.getElementById('code').value;
		l1.innerHTML = 'Connecting to ' ;
		l2.innerHTML = 'Connected to ' ;
		connected = true;
		l4.innerHTML = 'view bank';
		l5.innerHTML = 'upload [virus]';
		l8.innerHTML = 'disconnect [ip]';
		if(user == 'disconnect'){
			connected = false;
			l1.innerHTml = 'Disconnected Safely...';
		};
		if(user == 'view bank'){
			var pwrd = Math.floor( Math.random() * 1) - 10000;
			var nam = Math.floor( Math.random() * 1) - 10000;
			alert(pwrd);
		    alert(nam);
			var uname = 'user' + nam;
			var user = prompt('Username: ');
			var pass = prompt('Password: ');
			if(user == uname && pass == pwrd ){
			}
		};	
		if(user == 'upload'){
		    svirus= prompt('Enter Virus: ');
			for(var key in boughtviruses) {
				if(boughtviruses[key] == svirus) {
					l1.innerHTML = 'Uploading ' + svirus;
					l2.innerHTML = 'Virus Uploaded';
				}else{
					alert("You Don't Have This Virus!");
		  	};
            };
		};
	};
};

			.console{
				position: relative;
				height: 250px;
				width: 500px;
				background-color: #000;
				border-left: 10px solid #cccccc;
				border-top: 5px solid #cccccc;
				border-right: 10px solid #cccccc;
				border-bottom: 10px solid #cccccc;
			}
			.exit {
				float: right;
				background: #800000;

				height: 25px;
				border: none;
				width: 40px;

当您输入“-10000”作为密码和“user-10000”作为用户名时，工作正常
