i opened , populated database before codes run don't need ask thank u if u can me solve problem

but if add window.location.href = "deadlines.html" end of function insert db, redirect page, data not saved db

it's not strange @ all. insert operation asynchronous, means code starts it, finishes later (which why accepts callback).

if tell code take user away page, asynchronous operation cancelled before completes. you'll need wait , use code writing window.location.href within success callback.

e.g.:

function insertdeadlinetodb(dbid,dbdescription,dbclass,dbduedate, dbduetime, dbtype, dbadditionalinfo, dbfinished) {     //alert('insert called');      //alert('before insert');     db.transaction(function(tx){         tx.executesql(             'insert deadlines (id, description, class, duedate, duetime, type, additionalinfo, finished) values (?,?,?,?,?,?,?,?)',             [dbid,dbdescription,dbclass,dbduedate, dbduetime, dbtype, dbadditionalinfo, dbfinished], function() {                successcb();                window.href.location = "deadlines.html"; // <=== here             }, errorcb);         ////alert(tx);    });    //window.href.location = "deadlines.html";              <=== not here }

side note: code has missing variables, such successcb isn't defined anywhere.
