我在HTML頁面中有一個簡單的JavaScript腳本,當它包含在標題中時工作,但是當我嘗試將它放入單獨的文件並導入它時,它什麼都不做。HTML頁面中的JavaScript腳本塊在標題中工作,但不是從外部文件中工作
這裏的html頁面:
<!DOCTYPE html>
<html>
<head>
<meta content="en-us" http-equiv="Content-Language" />
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<style>
div#test{ border:#000 1px solid; padding:10px 40px 40px 40px; }
</style>
<script type="text/javascript" src="/js/script.js"> </script>
</head>
<body>
<h2 id="test_status"></h2>
<div id="test"></div>
</body>
</html>
和我的script.js代碼:
var pos = 0,
test, test_status, question, choice, choices, chA, chB, chC, correct = 0;
var questions = [
["What is 10 + 4?", "12", "14", "16", "B"],
["What is 20 - 9?", "7", "13", "11", "C"],
["What is 7 x 3?", "21", "24", "25", "A"],
["What is 8/2?", "10", "2", "4", "C"]
];
function _(x) {
return document.getElementById(x);
}
function renderQuestion() {
test = _("test");
if (pos >= questions.length) {
test.innerHTML = "<h2>You got " + correct + " of " + questions.length + " questions correct</h2>";
_("test_status").innerHTML = "Test Completed";
pos = 0;
correct = 0;
return false;
}
_("test_status").innerHTML = "Question " + (pos + 1) + " of " + questions.length;
question = questions[pos][0];
chA = questions[pos][1];
chB = questions[pos][2];
chC = questions[pos][3];
test.innerHTML = "<h3>" + question + "</h3>";
test.innerHTML += "<input type='radio' name='choices' value='A'> " + chA + "<br>";
test.innerHTML += "<input type='radio' name='choices' value='B'> " + chB + "<br>";
test.innerHTML += "<input type='radio' name='choices' value='C'> " + chC + "<br><br>";
test.innerHTML += "<button onclick='checkAnswer()'>Submit Answer</button>";
}
function checkAnswer() {
choices = document.getElementsByName("choices");
for (var i = 0; i < choices.length; i++) {
if (choices[i].checked) {
choice = choices[i].value;
}
}
if (choice == questions[pos][4]) {
correct++;
}
pos++;
renderQuestion();
}
window.addEventListener("load", renderQuestion, false);
