Summary

The find method is used to retrieve a limited list of contacts from the device's contact database. This method is best suited to access a small data set, where getAll() is better suited for a large data set.

Syntax

var instanceOfDomRequest = window.navigator.mozContacts.find(options);

Parameters

options
The find method expects some options to filter the contacts in order to reduce the size of the resulting list. The possible options are the following:
  • filterBy: An array of strings representing all the fields to filter by.
  • filterValue: The value to match against.  Because of Bug 1093105 if you are using the equals filterOp you will need to manually call toLowerCase() on any string values you pass in because the Contacts API normalizes all strings in its index but fails to normalize the passed-in filterValue in the case of equals.  startsWith automatically normalizes correctly.
  • filterOp: The filter comparison operator to use. Possible values are equals, startsWith, and match, the latter being specific to telephone numbers.
  • filterLimit: The number of contacts to retrieve.

Return value

A DOMRequest object to handle the success or error of the operation. In case of success, the request's result is an array of mozContact objects.

Example

var filter = {
  filterBy: ['name', 'nickname', 'firstName'],
  filterValue: 'zorro',
  filterOp: 'equals',
  filterLimit: 100
};

var request = window.navigator.mozContacts.find(filter);

request.onsuccess = function () {
  console.log(this.result.length + ' contacts found.');
}

request.onerror = function () {
  console.log('Something goes wrong!');
}
