Code / Description

Rather than using a mouse to click a button, or tabbing to the button and hitting the space bar, you can make Lotus Notes more like the Web by just hitting "Enter" to click the button. This is useful in things like search forms.

It uses a JS timer in the Notes Client to allow users to just hit Enter instead of clicking a button or using Space (i.e. in a search form). The timing in milliseconds can be decreased, but at a cost to the processing % used by the Client

Usage / Example

All are Client Javascript

1. YourSearchField onFocus event OR YourSearchForm onLoad event
// Check every 1/10 of a second
useClick = window.setInterval("runSearch()",100);

2. YourSearchField onBlur event OR YourSearchForm onUnload event
window.clearInterval(useClick);

3. YourButton
The button has an HTML Name/ID of "Button"

4. Form JS Header
var newline = String.fromCharCode(10);
var useClick;
var sString;
var t_sString;

function runSearch() {
sString = document.forms[0].YourSearchField.value;
if (sString.indexOf(newline)>=0) {
t_sString = replace(sString, '\n', '');
document.forms[0].YourSearchField.value = t_sString;
document.forms[0].elements['Button'].click();
}
}

function replace(str, from, to) {
var i = str.indexOf(from);
if (!from || !str || i == -1) return str;
var newstr = str.substring(0, i) + to;
if (i+from.length < str.length)
newstr += replace(str.substring(i+from.length,str.length),from,to);
return newstr;
}

Posted by Volker Mannherz on 07/20/2006 03:06:46 AMBug with onLoad event

Excuse me, but this tip is not working on my configuration (Win XP german keyboard layout / LN 6.5.3 EN)
if i use onFocus event of the search-field -> nothing happens
if i use onLoad event of the form -> i get about 20 msgboxes from my Search-Button click event and 131 new LN windows from msgboxes with error: "Too many recursive formula evaluations" (before Notes crashes)
Any Idea ?
