我正在编写一些代码，由于我不知道的原因，每当我单击按钮时，分配给它的函数都不会运行。有人知道为什么吗？提前谢谢。

<html>
<head>
</head>
<body>

<script>
function prime(number) {
var text = document.getElementById("p").innerHTML;
var n = 0;
for(var i = 2; i<number; i++){
if(number%i==0){
text = "Your number, "+number+", is divisible by "+i+"! It's composite!";
n = 1;
}
}
if(n==0){
text = "Your number, "+number+", is prime!";
}
}
function funcito(){
console.log("Functions!");
var number = document.getElementById("input");
prime(number);    
}
</script>

<p id="p"></p><br>
<form id="input">
Your Number: <input type="number" name="uInput"><br>
</form> 
<p>Click "Got my number" to find out!.</p>
<button onclick="funcito()" value = "Got my number">Got my number</button>
</body>
</html>

试试这个

<button onclick="funcito()" value = "Got my number">Got my number</button>

该代码还有一些其他问题，所以您不会得到您想要的结果。试试这个代码：

<html>
<head>
</head>
<body>

<script>
function prime(number) {
var text = document.getElementById("p");
var n = 0;
for(var i = 2; i<number; i++){
if(number%i==0){
text.innerHTML = "Your number, "+ number+", is divisible by "+i+"! It's composite!";
n = 1;
}
}
if(n==0){
text.innerHTML = "Your number" + number + " is prime!";
}
}
function funcito(){
console.log("Functions!");
var number = document.getElementById("input").value;
prime(number);    
}
</script>

<p id="p"></p><br>
<form>
Your Number: <input id = "input" type="number" name="uInput"><br>
</form> 
<p>Click "Got my number" to find out!.</p>
<button  onclick="funcito()" value = "Got my number">Got my number</button>
</body>
</html>

因为您写onclick="funcito"是错误的，所以写onclick="funcito()"。相反
