我已经尝试搜索此问题的解决方案，但仍未找到。 HTML 执行正常，但 Javascript 未执行。我已将其包含在 index.html 文件中并尝试使用外部 .js 文件。仍然无法让我的 javascript 执行。还有 CSS 不执行的问题。需要一些新的眼睛。谢谢...

document.getElementById(“after_submit”).style.visibility = “visible”;
document.getElementById(“number_correct”).innerHTML = “You got “ +
correct + “correct.”;
}
var messages = [ “Great job”, “That’s just okay”, “ You really need to
do better!”];
var range;
if (correct <1) {

if (correct > 0 && correct<3) {
range = 1;

if (correct>2) {
range = 0;

document.getElementById(“after_submit”).style.visibility = “visible”;
document.getElementById(“message”).innerHTML = messages[range];
document.getElementById(“number_correct”).innerHTML = “ You got “ +
correct + “ correct. “;
}
最佳答案
首先，您的 JavaScript 文件没有链接到您的 HTML。您可能需要添加:
<script src="main.js"><script>
(或者你的HTML被 chop 了，到最后了？)
在您的 HTML 中，您没有调用正确的 JavaScript 函数:
<input id= "button" type= "button" value= "Submit" onClick="function();">
现在，您的 JavaScript 读取
function check () { ... }
所以应该是onClick="check();"因为那是您的函数的名称。
