javascript - Shortening a huge list using an array value -


i need help,

as can see below, end having huge list of code accomplish onblur , on focus scenario div , input field. there way create "list" , loop through accomplish code line line? since have on 20 fields page of code quite long.

document.getelementbyid('f1').onfocus = function() {     document.getelementbyid('f1').style.border = '1px solid #0033cc'     document.getelementbyid('div_rssims_prefix').style.color = '#0033cc'     } document.getelementbyid('f1').onblur = function() {     document.getelementbyid('f1').style.border = '1px solid #abadb3'     document.getelementbyid('div_rssims_prefix').style.color = ''    } document.getelementbyid('f2').onfocus = function() {     document.getelementbyid('f2').style.border = '1px solid #0033cc'     document.getelementbyid('div_rssims_firstname').style.color = '#0033cc'  } document.getelementbyid('f2').onblur = function() {     document.getelementbyid('f2').style.border = '1px solid #abadb3'     document.getelementbyid('div_rssims_firstname').style.color = ''     } document.getelementbyid('f3').onfocus = function() {     document.getelementbyid('f3').style.border = '1px solid #0033cc'     document.getelementbyid('div_rssims_middlename').style.color = '#0033cc'     } document.getelementbyid('f3').onblur = function() {     document.getelementbyid('f3').style.border = '1px solid #abadb3'     document.getelementbyid('div_rssims_middlename').style.color = ''    }

an ideal list be:

f1,div_rssims_prefix f2,div_rssims_firstname f3,div_rssims_middlename

ect.

you can use javascript object map fields out, loop through object assign events.

working example: http://jsfiddle.net/jzcqv/1/

var objfocuspairs = {     "f1": "div_rssims_prefix",     "f2": "div_rssims_firstname",     "f3": "div_rssims_middlename" }  (var curid in objfocuspairs) {     document.getelementbyid(curid).onfocus = function(strid){         return function(){focusstyle(strid)};     }(curid);     document.getelementbyid(curid).onblur = function(strid){         return function(){blurstyle(strid)};     }(curid); }  function focusstyle(strid) {     document.getelementbyid(strid).style.backgroundcolor = 'aliceblue';     document.getelementbyid(objfocuspairs[strid]).style.color = 'mediumblue'; }  function blurstyle(strid) {     document.getelementbyid(strid).style.backgroundcolor = '';     document.getelementbyid(objfocuspairs[strid]).style.color = ''; }

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
