我正在制作一个表单，该表单应该在表单中提出三个问题并添加它们。如果结束值等于3，则应在单击提交按钮时打开另一个名为toggletab（）的函数。我尝试了这个，它告诉我通过或假，取决于价值，但它不会工作。我不擅长JavaScript，这对我来说真的很困惑。看起来它分别运行每个问题而不是等到结束并一起计算它们。我无法弄清楚为什么会这样。如果有人知道如何做，我也不确定如何调用另一个单独文件中的函数。
谢谢。这是HTML

这是JavaScript
function getscores1(score1) {
var getscores1 = (score1.value);
sendScores(getscores1);
}
function getscores2(score2) {
var getscores2 = (score2.value);
sendScores(getscores2);
}
function getscores3(score3) {
var getscores3 = (score3.value);
sendScores(getscores3);
}
function sendScores(getscores1, getscores2, getscores3){
var total = getscores1 + getscores2 + getscores3;
answer(total);
}
function answer(total) {
if (total == 3) {
document.getElementById('totalScore').innerHTML = "false";
} else{
document.getElementById('totalScore').innerHTML = "pass";
}
}
答案 0 :(得分：0)
您的函数定义的变量are not global。函数返回后，它们的值消失。因此，除非将它们作为参数传递，否则您的sendScores函数实际上无法访问这些值。但是当sendScores有3个参数时，你只发送一个（当你调用函数时也可以访问的那个）。
一种选择是将这些存储为全局变量，但全局变量是General Evil™。或者，您可以在单击“提交”时获取所有值。这是一个有效的例子。注意，当用户没有回答一个或多个问题时，这不会出现这种情况。点击＆＃34;运行代码段＆＃34;下面的按钮可以看到它的实际效果。
对于你的最后一个问题，你可以将你的js放在一个单独的文件中，然后将<script src="path/to/your/file/js"></script>放在你的html中加载它。
function answer(total) {
var score = 0;
if (document.getElementById('exp_yes').checked) {
score++;
}
if (document.getElementById('chg_yes').checked) {
score++;
}
if (document.getElementById('sus_yes').checked) {
score++;
}
if (score > 0) {
document.getElementById('totalScore').innerHTML = "false";
} else {
document.getElementById('totalScore').innerHTML = "pass";
}
