下面提到的javascript代码用于验证输入的aadhar号码是否有效。我想要做的是当用户输入aadhar号码时，它应该验证输入的号码是否有效。我使用了javascript用于验证但不起作用。
<script language="javascript" type="text/javascript">
var d = [
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[1, 2, 3, 4, 0, 6, 7, 8, 9, 5],
[2, 3, 4, 0, 1, 7, 8, 9, 5, 6],
[3, 4, 0, 1, 2, 8, 9, 5, 6, 7],
[4, 0, 1, 2, 3, 9, 5, 6, 7, 8],
[5, 9, 8, 7, 6, 0, 4, 3, 2, 1],
[6, 5, 9, 8, 7, 1, 0, 4, 3, 2],
[7, 6, 5, 9, 8, 2, 1, 0, 4, 3],
[8, 7, 6, 5, 9, 3, 2, 1, 0, 4],
[9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
];
$('#UserForm').formValidation({
message: 'This value is not valid',
feedbackIcons: {
valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'
},
fields: {aadhaar_no: {
validators: {
digits: {
message: 'Please use numeric characters only.'
},
stringLength: {
min: 12,
max: 12,
message: 'The aadhaar number must be 12 characters long'
}, identical: {
field: 'c_aadhaar_number',
message: 'The aadhaar number and its confirm field are not the same'
}, callback: {
message: 'The input string is not a valid Aadhaar number.',
callback: function (value, validator, $field) {
return validate(value);
}

问题是我只是尝试通过使用javascript来验证aadhar数字，但最后我得到了失败的结果。然后我尝试使用我成功的类来做它。所以，在webform中，我是使用一个文本框，一个标签和一个按钮。

//ScriptManager.RegisterClientScriptBlock(this, GetType(), "none", "<script>executeAfter();</script>", false);
// ClientScript.RegisterStartupScript(this.GetType(), "Popup", "validate();", true);
aadharcard aad = new aadharcard();
bool isValidnumber = aadharcard.validateVerhoeff(TextBox1.Text);
// aad.validateVerhoeff("");
//lblmsg.Text = TextBox1.Text + "valid number";
if (isValidnumber)
{
lblmsg.ForeColor = Color.Red;
lblmsg.Text = "valid number";
}
else
{
lblmsg.ForeColor = Color.Green;
lblmsg.Text = "Invalid number";
}
}

使用此算法来验证aadhara编号。对于其他语言，请参考此https://en.wikibooks.org/wiki/Algorithm_Implementation/Checksums/Verhoeff_Algorithm
