C# - How To Make Sure A String Is Clean For Insertion Into Javascript Alert('error Message')
Jun 24, 2010
I am trying to display an error to the user of a web page using a javascript alert popup, I currently have the following code to clean the error string:
errorMessage.Replace("'", "'")
But this is not sufficient as some illegal characters are not being removed, is there a static method somewhere in the framework that will format my string for clean insertion into html?Update: my initial question was slightly ambiguous. the string needs to be valid as in alert('this is some 'illegal text' that will not popup');I will try Server.HtmlEncode, hopefully it will do the trick.

I think the popup message is a poor idea because OnClientUploadError has already provided developers a good option to handle the error easily in whichever way they prefer. The worst is that if a user clicks OK, he will see a window that should be seen only by software developers. Is there any trick to stop the error alert?

I am fetching some data from Db and displaying it in a textarea using jquery in the following way.$('#textareatest').val('<% =teststring %>').It is possible that the string 'teststring' can contain XHTML line breaks(<br/>).whenever the string contains <br/> I am getting the 'unterminated string literal' error.I saw a number of posts considering '' as line breaks and suggesting to escape it.I tried to escape the <br/> similarly,but it didn't work.

In order to generate clean markup, I often resort to using code similar to this:
<asp:Literal ID="ltItem" runat="server">
<li class="{0}"><a href="{1}">{2}</a></li></asp:Literal>
And in the codebehind:
[code]....
Therefore my question:
Is this a common way to generate clean markup? Are there better alternatives? Is the databinding syntax approach preferable?

I'm doing an ajax work where web service will return data and on client side and I am creating html table with data.I am using var (to hold string of generated html code), do string concatenations to generate table, tr and td tags and put data in it. Then I put this html table with data into a div using innerHTML. I am applying inline css in this dynamic html code.
The issue I am facing is the web service will return a huge amount of data. What I tested is even on local machine it took about 10-12 minutes to process (concatenating, creating tags putting data in table, applying css) 10000 rows. Stored procedure just take 3-4 seconds in returning data. how this in-browser processing time can be reduced ? I am doing it for speed in some wrong way ? Or is there some technique for it or some method faster than innerHTML and string concatenations ?

I produce a popup window by adding a hyperlink to a table cell dynamically in my vb.net code behind. Here is the code:
Dim sHyperlink As
String =
"<a href=""LabPopup.aspx?RefNo=" & iLabRefNo &
""" target=""_blank"">" & strValue &
"</a>" objCellValue.Controls.Add(New LiteralControl(sHyperlink))
So on my web page, I will have a list of these hyperlinks and each have a different iLabRefNo. When I click on one of these links, the popup window does appear correctly.
I have a button on the popup window that closes the popup. But I get this message in an alert box when click on my button:
The webpage you are viewing is trying to close the window. Do you want to close the window?
If I click OK then the window close. But I just want to close the popup wondow without this message. What do I need to do?
Here is my code for the button to close the popup:
<asp:Button
ID="cmdLabPopupClose"
runat="server"
Text="Close"
OnClientClick="CloseWindow()"
/>
<script type="text/javascript">
function CloseWindow() {
window.close();
}
</script>
