Good day,
I am working on a c# web application, everything is working until I add in a normal JavaScript.
The html code is something as follow:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="scripts/JScript.js" type="text/javascript"></script>
<asp:ContentPlaceHolder id="headContent" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<asp:ContentPlaceHolder id="title" runat="server"></asp:ContentPlaceHolder>
<asp:ContentPlaceHolder id="bodyContent" runat="server"></asp:ContentPlaceHolder>
<!-- some code here -->
</body>
The JScript.js is the JavaScript that put in.
The JavaScript code is something as follow:
function getCookie(catId) {
var ebRand = Math.random() + '';
ebRand = ebRand * 1000000;
document.write('<scr' + 'ipt src="HTTP://bs.serving-sys.com/Serving/ActivityServer.bs?cn=as&ActivityID=553971&rnd=' + ebRand + '"></scr' + 'ipt>');
}
This JavaScript function will be trigger when a link button is click.
I hit error in IE but Chrome and Mozilla is working fine.
My error in IE console is
HTML1527: DOCTYPE expected. The shortest valid doctype is "<!DOCTYPE html>".
After search in Google, I try to put in
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
as new DOCTYPE, but it not working also.
and I have try put
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
inside <head></head>
But I still get the same error in IE also.
Is is problem in ContentPlaceHolder?
Other than that, I have go to W3C Markup Validation Service to do some validation of the address :
And go to http://validator.w3.org/check to put in <script src="HTTP://bs.serving-sys.com/Serving/ActivityServer.bs?cn=as&ActivityID=553971&rnd=20079.082210606393"></script>
as well.
But not understand what is the validation result means.
Kindly advise.
IE issues a warning about
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">, because such a string is not a valid doctype according to HTML5. The warning as such has no impact on anything. It’s just part of HTML5 evangelism.After you changed it to
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">, the issue was removed. But you probably saw the results of using some cached copy that has a wrong doctype. Testing with a fresh file (with a new name) should fix this issue.Of course, the code as such does not validate, since the ASP tags are taken literally and interpreted as
bodycontent, but that’s a different issue.The practical move is to use
<!DOCTYPE html>as suggested. If you wish to still validate against the XHTML 1.0 specification for example, you can do this using the validator’s user interface to override the doctype.But it’s not a big issue; you can just as well simply ignore the warning. If you have some functional errors, they are caused by something else and should be asked separately, with sufficient data provided.
