Answer 1

You are looking for change event:

$("#txt1").change(function(){
    $.post("Serversidefile.php?value="+$("#txt1").attr("value"));   
});

The change event fires when the contents of text box change.

Answer 2

why would you want to put the value in a textbox first? .change() is what you need :)

Answer 3

You could try the select event:

$("#txt1").select(function() {
    $.post("Serversidefile.php, { value: $(this).val() });   
});

Also notice that the value parameter is sent as the data hash and not concatenated in the url in order to be properly encoded.
