可能是脑力,但是, 每当我尝试在我的网络表单中针对广告验证我的凭据时,它总是返回true(已批准),为什么会这样?这只是一个测试,以确保每当我点击"提交"按钮:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<script type="text/javascript">
function kwadraat(){
var text = "", i,
t = parseInt(text2.value, 10),
demo = document.getElementById("demo"),
numm = t;
if (numm > 20) {
demo.innerHTML = 'Too Big!!!';
return;
}
for (i = 1; i <= numm; i++) {
text += "The number is " + i + "="+ (i*i) +"<br>";
}
demo.innerHTML = text;
}
</script>
</head>
<body>
Test<br>
<input type="text" id="text2">
<p id="demo"></p>
<button onClick="kwadraat()">Test</button>
</body>
</html>
答案 0 :(得分:2)
您的if
语句正在检查名为IsValid
的对象的真值。您创建的bool
名为isValid
。请注意,一个以资本开头,另一个则不是。
bool isValid
将不会存在于您的使用块之外,因为它在内部声明。将isValid
移到using语句之外,如下所示:
protected void Button1_Click(object sender, EventArgs e)
{
// Username and password text
var username1 = uniloginTextBox.Text;
var password1 = passwordTextBox.Text;
// isValid defaults to false
bool isValid = false;
// Check credentials against AD
using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, "cv.local"))
{
// Set value for isValid
isValid = pc.ValidateCredentials(username1, password1, ContextOptions.Negotiate);
}
// Achieves the same as your if statement
Label.Text = isValid ? "Approved" : "Denied";
}
