Javascript一个猜数字的小游戏

发表于   |   分类于   |  

今天学习了一个猜数字的小游戏的JS写法，方法很简单，现在写下来：

  1. 随机数的产生

    function randomize(){//取1-10随机数，其实是根据时间~~~~(>_<)~~~~  
    var now = new Date();  
    num = (now.getSeconds()) % 10;  
    num ++;  
}

  2. 猜数函数

    function guessIt(form){  
    if(form.tfield.value == num){  
        alert("Correct!");  
        form.tfield.focus();  
        trys = 0;  
        randomize();  
    }else{  
        trys ++;  
        alert(trys + " wrong. Try again!");  
        form.tfield.value = "";  
        form.tfield.focus();  
    }  
}

  3. HTML主体

    <body bgColor="lightgreen" onLoad="randomize()">  
    <center>  
        <b>pick a number between 1 and 10</b>  
        <form action="" name="myform">  
            <input type="textbox" size="4" name="tfield">  
            <p>  
                <input type="button" name="button1" value="Check my guess!" onCLick="guessIt(this.form)">  
            </p>  
        </form>  
    </center>  
</body>
