serialization - How to serialize & deserialize Javascript objects? -


i need serialize , deserialize javascript objects store them in db.

note these objects contain functions, can't store them json, can't use json2.js.

what's state of art in [de]serialization of javascript objects (in javascript of course).

thanks, stewart

in general, there's no way (in browser) serialize objects functions attached them, since every function has reference it's outer scope. if function references of variables, won't exist anymore when deserialize it.

what use built-in (or json2.js) json.stringify , json.parse functions replacer , reviver parameters. here's partial example of how work:

json.stringify(yourobject, function(name, value) {     if (value instanceof latlng) { // check name if want         return 'latlng(' + value.lat() + ',' + value.lng() + ')';     }     else if (...) {         // other type needs custom serialization     }     else {         return value;     } });  json.parse(jsonstring, function(name, value) {     if (/^latlng\(/.test(value)) { // checking name safer         var match = /latlng\(([^,]+),([^,]+)\)/.exec(value);         return new latlng(match[1], match[2]);     }     else if (...) {         ...     }     else {         return value;     } });

you can use serialization format want in custom types. "latlng(latitude,longitude)" format 1 way of doing it. return javascript object can serialized json natively.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
