Expected ';' - Javascript error in asp.net page

Luigi · Mar 15, 2010

Hi all,
in my ASP.NET 3.5 application I'm having this javascript error when I open
some pages:

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0;
SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media
Center PC 6.0; InfoPath.2; .NET4.0C; .NET4.0E)
Timestamp: Mon, 15 Mar 2010 11:12:39 UTC

Message: Expected ';'
Line: 206
Characted: 45
Code: 0
URI: mypath

and if I click F12 in IE8 to view the source of the page, the line 206
begins with:

var

WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID
= document.all ?
document.all["WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID"]
:
document.getElementById("WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID");

in the code:

<script type="text/javascript">

How can I solve this problem?

Thanks in advance.

= document.all ?

I appreciate that you're trying to evaluate whether document.all is
supported or not by the browser, but there's really no need to do this
anymore, as all modern browsers fully support document.getElementById(....)

Hello,

<script type="text/javascript">
//<![CDATA[
var
WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID.controltovalidate

WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID.display

WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID.evaluationfunction

WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID.validationexpression
=
WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID

document.all["WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID"]
:
document.getElementById("WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID");"WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateTextBoxID";"Dynamic";"RegularExpressionValidatorEvaluateIsValid";"^\\s*(\\d{1,2})([-./])(\\d{1,2})\\2((\\d{4})|(\\d{2}))\\s*$";

The statement ends after ...
document.getElementById("WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID");

Then the next statement is :
"WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateTextBoxID";

In the Production environment, there is IE 6.
In my machine I have the version 8.0.
Maybe is here the problem?

What is this?

WebCustomControl11_ucRicostruzioneMisure.ascx_Data_dateRegularExpressionValidatorID

You are trying to create a variable with such long id and a dot in the
name? If it's a name of existed control on the page, then what does
"var" in front of the line?

Mark Rae [MVP] · Mar 15, 2010

In the Production environment, there is IE 6.

Surely not! IE6 is now *completely* unsupported by Microsoft, as well as
being generally acknowledged as the worst version of any browser ever
released by any company, not just Microsoft...

In my machine I have the version 8.0.
Maybe is here the problem?

The problem is that you are using document.all - use document.getElementById
instead

Also see the advice from Patrice...
