我想输出一个函数secret();，所以它看起来像这样:
AAAA-BBB-<random string>
但它返回此错误:
Uncaught TypeError: secret is not a function
这是代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Random End String</title>
<script type="text/javascript">
function writeName() {
var welcomeMsg = document.getElementById('welcome');
var name = document.getElementById('name');
var alamat = document.getElementById('alamat');
var secret = secret();
var formContent = document.getElementById('entername');
welcomeMsg.innerHTML = "Your Identifier is " + name.value + "-" + alamat.value + "-" + secret + "";
formContent.innerHTML = "";
}
</script>
<script>
function secret() {
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
for (var i = 0; i < 5; i++)
text += possible.charAt(Math.floor(Math.random() * possible.length));
}
</script>
</head>
<body>
<p id="welcome"></p>
<form id="entername">
Your Name:<input type="text" id="name" /><br/> LockerID:
<input type="text" id="alamat" /><br/>
<input type="hidden" id="secret">
<input type="button" value="Submit" onclick="writeName();" />
</form>
</body>
</html>最佳答案
不要命名var Secret，在本例中将其更改为其他内容secret1工作正常。
编辑:您还需要返回您的“ secret 文本”。
完整的工作示例:
function writeName() {
var welcomeMsg = document.getElementById('welcome');
var name = document.getElementById('name');
var alamat = document.getElementById('alamat');
var secret1 = secret();
var formContent = document.getElementById('entername');
welcomeMsg.innerHTML = "Your Identifier is " + name.value + "-" + alamat.value + "-" + secret1 + "";
formContent.innerHTML = "";
}
function secret() {
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
for (var i = 0; i < 5; i++) {
text += possible.charAt(Math.floor(Math.random() * possible.length));
}
return text
}
function writeName1() {
var welcomeMsg = document.getElementById('welcome');
var name = document.getElementById('name');
var alamat = document.getElementById('alamat');
var text = "";
var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
for (var i = 0; i < 5; i++) {
text += possible.charAt(Math.floor(Math.random() * possible.length));
}
var formContent = document.getElementById('entername');
welcomeMsg.innerHTML = "Your Identifier is " + name.value + "-" + alamat.value + "-" + text + "";
formContent.innerHTML = "";
