Hi christopheEU ,

I found a better way for sending apostrophe as a parameter value.. use \ followed by ' will solve your problem..

Ex.

<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="ShowVaue('d','n\'avez vous');" />

H JaganUnique,

if i understand, you tell me place code :

c sharp :Value = Value.Replace("'","'");

and on javascript for to delete ' and replace by ' put:

Value = Value.Replace("'","';");

is it right ?

But, if just to test something and it's works

In my code c sharp, now i replace the ' by \\'

Value = Value.Replace("'", "\\'");

And it's works fine, when i click on the button no javascript fails and when the page is loading i see my string as : n'avez vous !

Now, why the double \\ ?

thanks

Christophe

christopheEU:
n'avez vous => i see after loading => n'avez vous !!!
And of course, i'd like to see n'avez vous

Any idea ?

again replace ' with '

some think lik this.. Value = Value.Replace("'","'");

Hi,

Thanks for your fast reply !

now if i put your code in my code c sharp like :

Value = Value.Replace("'", "'");

i execute the application, no fail when i enter value with ' but when the page is end of loading i see my value as for example:

n'avez vous => i see after loading => n'avez vous !!!

And of course, i'd like to see n'avez vous

Any idea ?

Thanks

Christophe

use escape characters code while sending ' (apostrophe) in a parameter. other wise it will treat as another parameter value and doesn't executes your code..

Ex: ' (for apostrophe)

javascript and bad character ?

Hi,

I'm a beginner with javascript and asp net, i work with visual studio 2005.

I have a javascript function who add a value in a listbox:

function ListAddItem(listBoxId, value)

{

...

}

This function is on a parent page and on this page i have several links.

when i click on a link a child page opens, on this page there are some text box, i enter some string and when i click the button

i call the opener.ListAddItem

script += "opener.ListAddItem('list1", '" + Value + "');";

that work of course, but there is a problem if i enter some string who contains some ' !!!

Ok before to call the function javascript i use string.replace("'","''"); in c sharp !

but that doesn't work because when i execute the code and enter a string with a ', the ' is well double '' but now my function fails because he think there are 3 parameter and not 2!!!

Have you got any idea ?

Thanks in advance

Christophe
