classname - javascript to change all class values in a div -


is there way change class value of buttons js? right i've got:

  var nodes = document.getelementsbyclassname("yui-button yui-radio-button");

and loop

  (i=0;i<nodes.length;i++) {      nodes[i].classname = "something";   }

is there anyway bypass loop , change class values?

here's html:

    <div id="season" align="center">      <div id="seasonbuttons" class="yui-buttongroup">       <span id="yui-gen0" class="yui-button yui-radio-button">        <span class="first-child">         <button type="button" id="yui-gen0-button">spring</button>        </span>       </span>       <span id="yui-gen1" class="yui-button yui-radio-button">        <span class="first-child">         <button type="button" id="yui-gen1-button">summer</button>        </span>       </span>       <span id="yui-gen2" class="yui-button yui-radio-button">        <span class="first-child">         <button type="button" id="yui-gen2-button">fall</button>        </span>       </span>      </div>     </div>

you can jquery

    $(".yui-button,.yui-radio-button").addclass("something").removeclass("yui-button yui-radio-button");

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...
