IDBDatabase.onabort

The onabort event handler of the IDBDatabase interface handles the abort event, fired when attempted access to the database is aborted.

Note: This feature is available in Web Workers.

Syntax

IDBDatabase.onabort = function(error) { ... };

Example

This example shows an IDBOpenDBRequest.onupgradeneeded block that creates a new object store; it also includes onerror and onabort functions to handle non-success cases.

DBOpenRequest.onupgradeneeded = function(event) {
  var db = event.target.result;
    
  db.onerror = function() {
    note.innerHTML += '<li>Error opening database.</li>';
  };

  db.onabort = function() {
    note.innerHTML += '<li>Database opening aborted!</li>';
  };

  // Create an objectStore for this database
    
  var objectStore = db.createObjectStore("toDoList", { keyPath: "taskTitle" });
    
  // define what data items the objectStore will contain
    
  objectStore.createIndex("hours", "hours", { unique: false });
  objectStore.createIndex("minutes", "minutes", { unique: false });
  objectStore.createIndex("day", "day", { unique: false });
  objectStore.createIndex("month", "month", { unique: false });
  objectStore.createIndex("year", "year", { unique: false });

  objectStore.createIndex("notified", "notified", { unique: false });
    
  note.innerHTML += '<li>Object store created.</li>';
};
