        //regex = /^\d+$/;
        regex = /(^-?\d\d*\.\d*$)|(^-?\d\d*$)|(^-?\.\d\d*$)/
        if ( regex.test( f.value ) ) {
                return;
        } else {
                alert("Please enter a number value");

Refresh a form keeping its field values

To refresh a form keeping its field values as is:

Copied the content from the above link:
Domino form / document refresh using JavaScript:

Better Option (Domino6 + ):
if(ValidationFunc()==true) {
return _doClick('$Refresh', this, null);
}

A longer version to specify a frame and what field to base refresh on:
return _doClick('$Refresh', this, '_self', '#_RefreshKW_' + 'somefieldname' );

To refresh the document

To refresh the entire document in client : @Command([ViewRefreshFields)
And to refresh entire document in web : _doClick('$Refresh', this, '_self', '#_RefreshKW_')

To run an agent from lotus notes webpage

To run a Lotus-script agent from a lotus notes webpage:

1) Write @Command([ToolsRunMacro]; "(MyWebAgent)") in the button's programmer pane Client > Formula and it will work when you click the button. No need to do Pass-thru HTML for this button.

If for some reason you are still not able to achieve your result, you can use an indirect approach, i.e.

2) In your button where you have written the code for running the agent, in it's Properties > HTML tab, give a name  and id to it. It's better if we keep the value for Name and ID same.

Then create another Button or link and in that write in the programmer pane Web > Javascript, document.forms(0).<the button's ID value>.click()

i.e. document.forms(0).btnCheckDuplicate.click()

Thus, the first button will be triggered with the click() event and your agent will run.

Proper way to logout a website...

Proper way to logout is a website in lotus notes:

After you use the default logout code you must redirect the page to another page.
This way if a PC is being used by multiple users it will not open the same session.
Once you redirect to another page, it kills the session completely post logout.

Syntax:
top.location = self.location.href.substring(0,self.location.href.indexOf('.nsf') +4) + "/<framesetname>?logout&redirectTo=http://"+window.document.forms[0].Server_Name.value+"/"+window.document.forms[0].DBNameTX.value+"/";

This is a response that I posted in IBM developers forum.
