我正在尝试制作一个简单的数字猜谜游戏：生成1到9999999999之间的随机数并打印到控制台。我希望用户在表单中输入他们的猜测 - 并保持循环猜测，直到猜测与随机数匹配。
这是我的HTML：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Random Number Guess</title>
</head>
<body>
<!--text display/button -->
<p>Try and "guess" the random number! Click "Generate new random number" to start"</p>
<div id="out1"></div>
<form id="promptUser">
Your guess:
<input type="text" id="inUserGuess">
<input type="submit" value="Submit">
</form>
<br>
<button id="btn1">Generate new random number</button>
<div id="in1"></div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>/*SEE SCRIPT BEOW */</script>
</body>
</html>
这里是javascript / jquery：
$(document).ready(function() {
/*initialize random number*/
var randNum = Math.round(Math.exp(Math.random()*Math.log(10000000-0+1)));
console.log(randNum);
var win = false;
while (win = false) {
$('#promptUser').on('submit', function(e){
e.preventDefault;
var userGuess = $('#inUserGuess').val();
console.log("User guess:" + userGuess);
});
/*yes: "congrats! start again"*/
if (userGuess == randNum){
console.log("User guess is correct");
alert("You got it! Try another round.");
win = true;
}
/*no: "not quite. guess again."*/
else {
console.log("user guess is incorrect");
alert("Not quite. Guess again.");
win = false;
}
}
为了让用户猜测直到他们做对了，我将猜测输入放在while循环中并使用if和else语句来确定他们的猜测是否与随机数匹配。
似乎代码在if / else语句之前的某个地方搞砸了 - 控制台日志永远不会显示出来。相反，按下提交时会生成一个新的随机数。
我知道收集输入的语法 - 在我尝试给用户无限猜测之前if语句运行正常（尽管在每次“play”之后自动生成一个新的随机数，无论正确/不正确的猜测）
我觉得这很愚蠢 - 但我已经花了好几个小时摆弄它。
[[EDIT]]我现在让提交按钮事件处理程序执行两项操作：将用户输入存储到userGuess并检查它是否与randNum匹配，但仍然陷入无限循环：
<script>
/*initialize random number*/
var randNum = Math.round(Math.exp(Math.random()*Math.log(10000000-0+1)));
console.log(randNum);
var userGuess = "";
do {
$(document).ready(function() {
$('#promptUser').on('submit', function(e){
e.preventDefault;
userGuess = $('#inUserGuess').val();
console.log("User guess:" + userGuess);
if(userGuess == randNum){
console.log("user guess is correct");
alert("That's right! Play again.");
}
else{
console.log("user guess is incorrect");
alert("Not quite. Guess again.");
}
});
});
}
while (userGuess != randNum);
/*generate new random number each on button click */
$('#btn1').on('click', function(){
var randNum = Math.round(Math.exp(Math.random()*Math.log(10000000-0+1)));
console.log(randNum); /*(return random number to console for cheating)*/
});
</script>
