jQuery changing SELECT not working properly -


(using jquery mobile) have reset button needs reset of dropdown boxes selectedindex equal 0. believe index zero, value shown on select box not correct. keeps same value.

heres jsfiddle

for example: select 'unit2' , click reset. click ok. value shown on select box 'unit2' whereas should '--units--'

html 

<div data-role="fieldcontain" class='seltype' id='xmep' >   <select id="dmep" data-mini='true'>     <option value="0">--units--</option>     <option value='1'>unit1</option>     <option value='0.01'>unit2</option>     <option value='10'>unit3</option>   </select> </div>

.

.

jquery

$(document).ready(function() {   $('#rstbtn').click(function() {      var answer = confirm('click ok set selectindex equal 0');          if (answer == false) {             return;         } else {             $('select').prop('selectedindex', 0);         }   });  });

you need refresh select menu using .selectmenu('refresh',true).

demo

$(document).ready(function() {   $('#rstbtn').on('click', function() {      if (confirm('click ok set selectindex equal 0')) {          $('#dmep').val(0).selectmenu('refresh',true);       }   }); });

this more precise

  $('#dmep').find('option[value="0"]')   .prop('selected', true).addback()    .selectmenu('refresh', true);

or

   $('#dmep').prop('selectedindex', 0)    .selectmenu('refresh', true);

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...
