返回输出函数javascript内部html
返回输出函数javascript内部html
提问于 2018-08-03 02:22:59
我想输出一个function secret();，这样它看起来就像这样：
AAAA-BBB-<random string>但它返回以下错误：
未捕获TypeError: secret不是函数
代码如下：
<!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>

不要为var secret命名，在本例中将其更改为其他名称“secret1 works fine”。
编辑:你还需要返回你的“秘密文本”。
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 = "";
}<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Random End String</title>
</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>
Your Name:<input type="text" id="name1" /><br/> LockerID:
<input type="text" id="alama1t" /><br/>
<input type="hidden" id="secret1">
<input type="button" value="Submit" onclick="writeName1();" />

您的局部变量secret隐藏了您的函数secret。只需将变量重命名为其他名称即可解决此问题
function writeName(){
var welcomeMsg = document.getElementById('welcome');
var name = document.getElementById('name');
var alamat = document.getElementById('alamat');
var secret = secret(); //right here this is your issue
var formContent = document.getElementById('entername');
welcomeMsg.innerHTML = "Your Identifier is "+name.value+"-"+alamat.value+"-"+secret+"";
formContent.innerHTML = "";
