javascript - save handsontable to persistent state -


i have created table using handsontable:

hot = new handsontable(container, {         data: [],         dataschema: {id: null},         startrows: 5,         startcols: 1,         colheaders: ["car"],         columns: [           {data: 'id'}         ],         rowheaders: true,         minsparerows: 1,         persistentstate: true,         onchange: function (change, source) {             console.log(change);             console.log(source);         }       });

they have pretty elaborate example on saving/loading to/from server using ajax. however, want use persistent state save load stuff.

in particular want when cell's value in hot changed want save information in local storage, can retrieve later. closest got use change parameter in onchange , save manually localstorage. main question how can save cell's info once changed local storage? better persistentstorage.

also, can save whole hot table local storage? more efficient update whole table every time, or update value of particular cell? there quick way load table? can provide example how can save/load table local storage on change?

eventually, went this:

hot = new handsontable(container, {         data: [],         dataschema: {id: null},         startcols: 4,         colheaders: ["id"],         columns: [           {data: 'id'}         ],         rowheaders: true,         minsparerows: 4,         afterchange: function (change, source) {             // restore table after reload of page             if (source === "loaddata") {                 // load data local storage                 if (localstorage['data']) {                     var data = json.parse(localstorage['data'])                     this.loaddata(data);                     this.render();                     return                 }              }             else {                 // save data local storge if edit happends                 localstorage['data'] = json.stringify(this.getdata());                 return             }         }     });

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
