json - Prettify stringified object in javascript to serve in a static html page -

-

i'm trying use code prettify json object retrieved service , return in static page (has be).

the javascript functions work i'm having issues dealing stringified object.

it works fine encoding example before return statement html

json = "{\"a\":\"b\",\"c\":\"d\"}"

and not using stringify not using json.stringify real json object instead.

function getstaticresponse(jsonobjectretrieved){   return '<html>'             + '<head>'                 + '<title>' + 'title' + '</title>'                 + '<link rel="stylesheet" type="text/css" href="'                     + '/something' + '">'             + '</head>'               + '<body>'               + '<pre class="json-output box bg-color-weight-6 font-calibri">'               + jsonformat(json.stringify(jsonobjectretrieved))               + '</pre>'             + '</body>'           + '</html>'; }  function transformjson(k, v) {   if (k === 'href' && typeof v === 'string') {       var label = v.replace(/&/gi, '&amp;');     return '<a href=' + v + '>' + label + '</a>';   }   return v; }  function jsonformat(jsonstring) {     var jsonobj = json.parse(jsonstring, transformjson);     return json.stringify(jsonobj, undefined, 2)             .replace(/\s"(\w*)":/g, ' "<span class="key">$1</span>":')             .replace(/:\s"(.*)"/g, ': "<span class="string">$1</span>"'); };

many thanks

try removing call json.stringify @ jsonformat(json.stringify(jsonobjectretrieved))

var json = "{\"a\":\"b\",\"c\":\"d\"}";    function getstaticresponse(title, jsonobjectretrieved) {      return '<html>'            + '<head>'            + '<title>' + title + '</title>'            + '<link rel="stylesheet" type="text/css" href="'            + 123 + '">'            + '</head>'           + '<body>'            + '<pre class="json-output box bg-color-weight-6 font-calibri">'            + jsonformat(jsonobjectretrieved)            + '</pre>'            + '</body>'           + '</html>';  }    function transformjson(k, v) {    if (k === 'href' && typeof v === 'string') {      var label = v.replace(/&/gi, '&amp;');      return '<a href=' + v + '>' + label + '</a>';    }    return v;  }    function jsonformat(jsonstring) {    var jsonobj = json.parse(jsonstring, transformjson);    return json.stringify(jsonobj, null, 2)      .replace(/\s"(\w*)":/g, ' "<span class="key">$1</span>":')      .replace(/:\s"(.*)"/g, ': "<span class="string">$1</span>"');  };    document.write(getstaticresponse("abc", json));
