Referencing Javascript Object in another object -


this question has answer here:

what's best way reference javascript object exists inside of javascript object? instance, taking data below, how refer "home" of individual, reference object (places) in same dataset?

var data = {     "people": [{         "name": "jack",         "age": "8",         "home": data.places[0].country     }, {         "name": "john",         "age": "9",         "home": data.places[1].country     }],     "places": [{         "country": "holland"     }, {         "country": "germany"     }] }

split declaration data.places exist when reference it.

var data = {     "places": [{         "country": "holland"     }, {         "country": "germany"     }] }  // data defined , has property "places"  data.people = [{     "name": "jack",     "age": "8",     "home": data.places[0].country // no more error  }, {     "name": "john",     "age": "9",     "home": data.places[1].country // no more error either }]

in question, object referencing elements on before had been defined. resulted in typeerror: cannot read property 'places' of undefined. in solution, broke apart object definition when define data.people data.places piece array exists.

objects don't have declared @ once.

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...
