Question

This includes a sample code from a previous question “IndexedDB Fuzzy Search“.
How can I bound the cursor result to a input box to create a auto-complete effect and fill multiple input boxes of a form with the different values from the objectStore when a result is chosen? I would like to do this without any libraries.

The HTML input boxes.

 <input name="name" id="name"> //search by name, when a name is selected the last name and age are automatically attached to the other input boxes
 <input name="lastname" id="lastname">
 <input name="age" id="age">

The Javascript.

var result = [];
db.transaction(['table'], IDBTransaction.READ_ONLY)
.objectStore('table')
.openCursor(
IDBKeyRange.bound(searchTerm, searchTerm + '\uffff'),
IDBCursor.PREV)
.onsuccess = function (e) {
    e || (e = event);
    var cursor = e.target.result;
    if (cursor) {
        result.push([cursor.value.column1, cursor.value.sortcolumn]);
        cursor.continue();
    } else {
        if (result.length) {
        result.sort(function (a, b) {
         return a[1] - b[2];
      });
    }

    // Process code here
    }
};

Well, in your case you might only want the first result that cursor return, so you just need to check is there a result returned, something like this:

<input name="name" id="name">
<input name="lastname" id="lastname">
<input name="age" id="age">
<script>
document.getElementById('name').oninput = function () {
  var searchTerm = this.value;

  var result = [];
  db.transaction(['table'], IDBTransaction.READ_ONLY)
    .objectStore('table')
    .openCursor(
      IDBKeyRange.bound(searchTerm, searchTerm + '\uffff'), // The important part
      IDBCursor.PREV)
    .onsuccess = function (e) {
      e || (e = event);
      var cursor = e.target.result;
      if (cursor) {
        // Here I assume that your table with 'lastname' and 'age'

        // Return result to "lastname" input
        document.getElementById('lastname').value = cursor.value.lastname;

        // Return result to "age" input
        document.getElementById('lastname').value = cursor.value.age;
      }
    };
}
</script>
