gus;
I am working on a message control that looks like this windows message box.
in this control i used code that produce elements at run-time the code below:

JavaScript

var buttonsbar = $get(this.get_element().id + '_buttonsbar');
var okButton = document.createElement('input');
okButton.type = 'button';
okButton.id = this.get_element().id + '_okButton';
okButton.value = this._okbuttontext;
okButton.className = '__mycontrols_button';
okButton.dialogResult = MyControls.DialogResult.OK;
okButton.setAttribute('onclick', 'javascript:$find(\'' + this.get_element().id + '\').AcceptDialog(\'' + okButton.dialogResult + '\');');
buttonsbar.appendChild(okButton);

my problem is when i click the okButton AcceptDialog() is not hit in the compatibility view but it is hit when i turn of the compatibility view;

Try this:

JavaScript

okButton.onclick = SomeFunction;

Sir;
I took your advice and replaced the line

JavaScript

okButton.setAttribute('onclick', 'javascript:$find(\'' + this.get_element().id + '\').AcceptDialog(\'' + okButton.dialogResult + '\');');

with

JavaScript

okButton.messageboxid = this.get_element().id;
okButton.onclick = function() { $find(this.messageboxid).AcceptDialog(this.dialogResult) };

by setting the onclick event to a reference of type function, but i use it in a new function because i want to pass a parameter to function AcceptDialog and I add messageboxid to the button because I lose context when the button is clicked.

this works great, but is there any way else to do so?

Is there a reason you want to do it another way? Here is one small trick that can make your code look a little cleaner:

JavaScript

function create_handleOkClick (boxId, dialogResult) {
  return function() {$find(boxId).AcceptDialog(dialogResult); };
}
// In another area of code...
okButton.onclick = create_handleOkClick(this.messageboxid, this.dialogResult);

You could also do this:

JavaScript

function create_handleOkClick (instance) {
  return function() {$find(instace.messageboxid).AcceptDialog(instance.dialogResult); };
}
// In another area of code...
okButton.onclick = create_handleOkClick(this);

No, just trying to learn other techniqes.

i liked the "return function()" this would be better then editing code for 7 buttons.

and one more thing, be gentle with me so i can love you
and as you maight know my heart is so weak (you could kill me with your "Is there a reason you want to do it another way?").

Sir;
I worked on this:

JavaScript

var create_handler = function(context, method, prameter) {
     var methodname = 'AcceptDialog'; // method.getName();
     return function() { context[methodname](prameter); };
}
button1.onclick = create_handler(this, this.AcceptDialog, button1.dialogResult);

I added the parameter 'method' as i may need to invoke one of the three methods; this.AcceptDialog(), this.Close(), this.DoPostBack(). The 'context' parameter i used it instead of function $find().

what happend whit me is that I couldn't extract the method name
so I am wondering if you could help me with this;

I am a little confused as to what you are after, but here are a few samples that may demonstrate what you are looking for:

JavaScript

var create_handler = function (context, methodName, parameter) {
  create_handler[methodName](context, parameter);
};
create_handler.AcceptDialog = function (context, parameter) {
  alert("Accepting...");
};
create_handler.Close = function (context, parameter) {
  alert("Closing...");
};
create_handler.DoPostBack = function (context, parameter) {
  alert("Posting...");
};

// Test.
create_handler(this, "AcceptDialog", "a parameter");
create_handler(this, "Close", "a parameter");
create_handler(this, "DoPostBack", "a parameter");

And another:

JavaScript

var create_handler = function (context, method, parameter) {
  method(context, parameter);
};
create_handler.AcceptDialog = function (context, parameter) {
  alert("Accepting...");
};
create_handler.Close = function (context, parameter) {
  alert("Closing...");
};
create_handler.DoPostBack = function (context, parameter) {
  alert("Posting...");
};

// Test.
create_handler(this, create_handler.AcceptDialog, "a parameter");
create_handler(this, create_handler.Close, "a parameter");
create_handler(this, create_handler.DoPostBack, "a parameter");

And another:

JavaScript

var myContext = "hello";
var create_handler = function (context, method, parameter) {
  method.call(context, parameter);
};
create_handler.AcceptDialog = function (parameter) {
  alert("Accepting..." + this);
};
create_handler.Close = function (parameter) {
  alert("Closing..." + this);
};
create_handler.DoPostBack = function (parameter) {
  alert("Posting..." + this);
};

// Test.
create_handler(myContext, create_handler.AcceptDialog, "a parameter");
create_handler(myContext, create_handler.Close, "a parameter");
create_handler(myContext, create_handler.DoPostBack, "a parameter");

Hi,

By using JqueryCurrency i am reading the currency symbold based on locale, but when i am trying to read the UK currency symbol, instead of pound symbol it is reading some junk data.
Any one faced the same problem please let me know the solution to read the pound symbol.

Thanks in Advance.

Populating a textbox inside usercontrol thru jquery.

Hi,
I have a usercontrol embedded in my content page.This usercontrol has a text box in it.

The label and regular expression validators on the page use ucid:txtboxid for associatedcontrolid/ControlToValidate respectively.

Now i try to populate the textbox in usercontrol using jquery as follows:

<br />
$("#<%= ucid:txtboxid.ClientID %>").val(myvalue);<br />

this gives a compilation error. I tried a few combinations of brackets but no luck.I then tried

<br />
$("#<%= ucid.ClientID %>").val(myvalue);<br />

and it builds fine but value doesn't get assigned at runtime.

How do I populate the usercontrol textbox?

Thanks

Say you have this user control, "Hello.ascx":

ASP.NET

<%@ Control Language="C#" %>

<asp:TextBox ID="txtInfo" runat="server" />

You can then get the ClientID of txtInfo using FindControl from "Default.aspx":

ASP.NET

<%@ Page Language="C#" %>
<%@ Register Src="~/Hello.ascx" TagPrefix="my" TagName="Hello" %>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Sub-Control Client ID</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.2.min.js"></script>    
        <my:Hello ID="helloWorld" runat="server" />
        <script type="text/javascript">
            $("#<%= helloWorld.FindControl("txtInfo").ClientID %>").val("Hello World");
        </script>
    </div>
    </form>
</body>
</html>

You could probably also add a property to your Hello control that returns the ClientID of txtInfo, then you'd simply get the ID by saying helloWorld.InfoClientID.

You have to escape the ' in a string literal with a \

Tooltip(true,escape('Benito\'s Taco Shop'),event)

or you could wrap the string in double-quotes instead:

Tooltip(true,escape("Benito's Taco Shop"),event)

The simple way to do this is to use decodeURI. Funnily enough, you can use encodeURI to encode a URI as well.

thank you, man. +5
good to learn a new pre defined function
but what i need is to decode a string containing the codes '%24' and '%2F' to the charactors '$' and '/'
so i defined the functions as

JavaScript

function UrlEncode (strinput) {
        var outcome = new String(strinput);
        var replacements = ['%21', '%2A', '%27', '%28', '%29', '%3B', '%3A', '%40', '%26', '%3D', '%2B', '%24', '%2C', '%2F', '%3F', '%25', '%23', '%5B', '%5D'];
        var entities = ['!', '*', '\'', '(', ')', ';', ':', '@', '&', '=', '+', '$', ',', '/', '?', '%', '#', '[', ']'];

        var i = 0;
        for (i = 0; i < entities.length; i++)
            outcome = outcome.replace(entities[i], replacements[i]);

        return outcome;
    }

but it replaces just the first occurrence of any code.

what mistake i have done?

In javascript we have built in method like unescape and escape

escape - method is used to encode
unescape -method is used to decode

(i.e)
var encodeSymbol = unescape("!");

encode the symbol ! to("%21")

var decodeSymbol = unescape("%21");

decode the %21 to symbol !

, Man.
Sir;
I found on W3Schools this note
Note: The escape() function should not be used to encode URIs. Use the encodeURI() function instead.

Could you please tell me why.

*Please consider the function decodeURIComponent()
