Simulate keypress

[Christian]

Hello,

As the subject says it, is there a way to simulate a special keypress in JS
? In my case, on loading an HTML page, i'd like to set the cursor at the end
of the input text of an <input type=text ...> object.
focus() sets the cusor at the beginning

Any idea ?

First of all sorry about my poor English, i´ll try to do the best.

Well, i´m having a similar problem because i wan´t to select certaint
characters from a text box. Maybe this routine i´ve just created , solves
your problem.

This routine, selects in a textbox characters from StartIndex to EndIndex.
If you gives to the routine both parameters with textbox content lenght, i
think it puts the cursor in the desired position.

function selectFromTo (textInput, charStartIndex, charEndIndex) {

/* We´ll calculate the appropiate value to the different moves. */
strTextInputValue = "" + textInput.value;

charStartIndex = (parseInt(charStartIndex) - 1);

numEndIndex = parseInt(charEndIndex);
numEndIndex -= strTextInputValue.length;
charEndIndex = numEndIndex.toString();

if (textInput.createTextRange) {
var range = textInput.createTextRange();
range.moveStart('character', charStartIndex );
range.moveEnd('character', charEndIndex);
range.select();
}
}

Thanks for the reply. I eventually found a similar answer on google, using
createTextRange. That will solve my problem, though i doubt this will work
on every browser.

For a more general matter, is there a way to simulate a keypress ?
