Enter key start onblur event and not onkeyup/onkeydown

[naamabm]

On my web I display configuration info, that user can edit, in a table.The correct user behavior should be to press Enter key after editing the field in order to set the changes. If he "leaves" the field without pressing Enter- the changes will be dismiss.In order to do that- I use "onkeyup" and "onblur""onkeyup"(1) set a flag that field's content has been changed(2) if the key is Enter (==13) , it sends the server a set request with the current value(*) also tried "onkeypress" or "onkeydown""onblur" - check the flag if the field's content has been changed. if so- send a refresh request to server that re-send current saved data (and erase user's changes).I recently noticed that while it works great in Chrome, on Explorer pressing the Enter key sets both events, and sometimes only the "onblur" event, thus ignores user's requests....Do you have any idea how to deal with it?THANKS!!!! -------------------------------------------------------code sample: <!-- Line LO freq --><tr><td><div id=div_lof_a><a href="manual.html#lof_mod" target="_blank">BUC LO Freq</a></div></td><td><div id=div_lof_select><input id="lof" value="" onkeyup="set_is_unsaved_change();if ((event.keyCode==13) && (div_img_no_touch.className=='no_touch_hide') && (is_positive_num(this))) {div_img_long_action.className='wait_img_show';div_img_no_touch.className='no_touch_show';updateStatusParams('query.fcgi','form_state=2&form_name=line_mod&field_name=lof&field_val='+this.value);reset_is_unsaved_change();}" onblur="if(is_set_unsaved_change()) {reset_is_unsaved_change();updateStatusParams('query.fcgi','form_state=1&form_name=line_mod');}"></div></td></tr>
