place javascript variables in html - several ways, which one to choose? -


i'm on html have place variables in depency of language choosen user. several reasons able client-side.

i have figured out different ways so, i'm asking myself best way (best way in case means "fastest", "most fail-safe" , on).

the variables stored in json-file looking this:

lang = { "nav" : {     "categories" : {         "header" : {             "de" : "kategorien",             "en" : "categories"         },     },     "search" : {         "placeholder" : {             "de" : "suchen nach...",             "en" : "search for..."         },         "button" : {             "de" : "finden",             "en" : "find"         },     }, }, "benefits" : {     "first" : {         "title" : {             "de" : "irgendwas",             "en" : "something"         },         "content" : {             "de" : "blablabla",             "en" : "blablabla in english"         },     },     "second" : {         "title" : {             "de" : "irgendwas anderes",             "en" : "something else"         },         "content" : {             "de" : "noch mehr blablabla",             "en" : "some more blablabla in english"         },     }, }, }

now place variables directly using little script everywhere shall be, example:

<script>document.write(lang.nav.search.button[language])</script>

on other side instead of script place 

<span id="lang.nav.search.button"></span>

or other tag , have external javascript replace/append/prepend or whatever.

to make bit more complicated, in cases have set attributes of elements in dependency of choosen language, , because direct execution of script above inside tag set attribute isn't possible (or there way so?) use function parent element of current position in dom

function scriptparent() {   var scripts = document.getelementsbytagname('script');   return scripts[scripts.length - 1].parentnode; };

and set attribute this:

<div class="form-group">     <input type="text" class="form-control">     <script>scriptparent().firstelementchild.placeholder = lang.nav.search.placeholder[language];</script> </div>

when finished project there between 50 - 100 variables, so, suggestion way prefer? or maybe has better way deal it?

thanks in advance!
