                document.getElementById("res").innerHTML = "Numbers Matched: 1\nPosition Matched: 1";
            }
            else if (l1[1] == l2[0] & l1[0] != l2[0]) {

        }

            else if (l1[0] != l2[0] & l1[0] != l2[1]) {
                document.getElementById("res").innerHTML = "Numbers Matched: 0\nPosition Matched: 0";
            }

        }

    }

}

当我单击检查按钮时，必须调用 cal（）函数。但是它显示以下错误：

Uncaught ReferenceError: cal is not defined
    at HTMLButtonElement.onclick (com_hrd.html:36)

我无法解决。实际上，该按钮应该起作用。而且我应该能够看到我给的句子“数字位置”。但是不知道为什么它不起作用。

Answer 1

在return函数中写入break而不是cal()。它是非法使用。

if (N1 == Num) {
    document.getElementById("res").innerHTML = "BINGO!!! You Won!! \n Reload the Page \n To play Again";
    return;
}

Answer 2

该函数中有一个非法的break语句，但这不能解释您得到的错误。您的环境肯定有其他问题。我将检查以确保您的JS文件实际上位于HTML引用的位置。工作提琴供参考（固定了非法中断）：https://jsfiddle.net/keegangbrown/deapmrjo/

Answer 3

在除去放错位置的break并注释掉引发安全性错误的localstorage语句之后，此代码似乎可以正常工作。我将该值硬编码为99进行测试...尝试在下面运行它。

//document.getElementById("res1").innerHTML = localStorage.getItem("textvalue3");
function generate() {
    var N = Math.floor(Math.random() * 100) + 1;
    //return N
    return 99;
}
function msg() {
    var x = document.getElementById("snackbar");
    x.className = "show";
    setTimeout(function () { x.className = x.className.replace("show", ""); }, 3000);
}
var Num = generate();

function cal(a) {
    N1 = a;
    if (N1 == Num) {
        document.getElementById("res").innerHTML = "BINGO!!! You Won!! \n Reload the Page \n To play Again";
        console.log('BINGO');


    }
    else {
        l1 = [];
        a1 = N1.toString();
        for (var i = 0, len = a1.length; i < len; i += 1) {
            l1.push(+a1.charAt(i));
        }
        l2 = [];
        a2 = Num.toString();
        for (var j = 0, len = a2.length; j < len; j += 1) {
            l2.push(+a2.charAt(j));
        }
        if (l2.length == 1) {
            if (l1.length == 2) {
                if (l1[0] == l2[0] & l1[1] != l2[0]) {
                   document.getElementById("res").innerHTML = "Numbers Matched: 1\nPosition Matched: 1";
                }
                else if (l1[1] == l2[0] & l1[0] != l2[0]) {
                    document.getElementById("res").innerHTML = "Numbers Matched: 1\nPosition Matched: 0";
                }
                else if (l1[0] == l2[0] & l1[1] == l2[0]) {
                    document.getElementById("res").innerHTML = "Numbers Matched: 1\nPosition Matched: 0";
                }
                else {
                    document.getElementById("res").innerHTML = "Numbers Matched: 0\nPosition Matched: 0";
                }
            }
            else if (l1[0] != l2[0]) {
                document.getElementById("res").innerHTML = "Numbers Matched: 0\nPosition Matched: 0";
            }
        }
        else if (l2.length == 2 & l1.length == l2.length) {
            if (l1[0] == l2[0] | l1[1] == l2[1]) {

        }
        else if (l2.length == 2 & l1.length < l2.length) {
            if (l1[0] == l2[0]) {
                document.getElementById("res").innerHTML = "Numbers Matched: 1\nPosition Matched: 1";
            }
