这是我的第二个问题,我想问你们这是什么问题:

<script lang="text/javascript">
function firstQ(){
var firstQuestion = document.getElementById('firstQuestion').value;
if(firstQuestion == '5'){
document.getElementById("firQ").innerHTML = "Correct";
} else {
document.getElementById("firQ").innerHTML = "Wrong!";
}
}
</script>
</head>
<body>
<form name="firstQ" action="">
<p>Q1. What is 2 + 3?</p>
<input type="text" id="firstQuestion" name="firstQ">
<input type="button" id="firstQ" value="answer" onclick="firstQ()">
<br>
<p id="firQ"></p>
</form>
</body>
</html>
我想如果数字5在变量中,我想在输入框下方显示“正确”一词。
有人可以帮助我吗?
[对不起,如果我的语法错误。我的英语不好]

id
为firstQ
,与您的函数名相同,这会引起冲突。调整输入id
。仅供参考:如果您打开了开发人员的工具(在任何浏览器中都为F12),并查看了“控制台”选项卡,则可能会看到错误:firstQ is not a function
,这表明该工具存在问题。 JS运行时查找您的函数。在确认您确实拥有具有该名称的功能之后,您可以尝试找出为什么无法识别它的原因。

您多次使用FirstQ作为名称和ID。由于FirstQ的过度使用,该功能无法运行。我相信这是对您问题最简单的答案。
