一、猜数字
页面如下:
我们想在文本框输入我们想猜的数字,点击猜后下面就会提示我们猜的数字是否正确,以及大了还是小了。
html代码:
<button id="reset">重新开始一局游戏</button><br/>请输入要猜的数字:<input type="text" id ="guessNum"><button id="userGuess">猜</button><br/>已经猜的次数:<span id="count"></span><br/>结果:<span id="result"></span>
点击 猜 按钮的js代码:
var number = Math.floor(Math.random() * 100) + 1;//要猜的数字console.log("number:" + number);//答案var count = 0;//点击猜,看看猜的数字对不对$(document).ready(function() {$("#userGuess").click(function() {count++;$("#count").text(count);var guessNum = $("#guessNum").val();if(guessNum > number) {$("#result").text("猜大了");$("#result").css("color", "red");} else if(guessNum < number) {$("#result").text("猜小了");$("#result").css("color", "red");} else {$("#result").text("猜对了");$("#result").css("color", "green");}});});
点击 重开游戏 按钮的js代码:
//点击重开游戏$(document).ready(function() {$("#reset").click(function() {number = Math.floor(Math.random() * 100) + 1;console.log("要猜的数字:" + number);count = 0;$("#count").text("");$("#result").text("");$("#result").css("color", "");$("#guessNum").val("");});});
