 |
|
AutoComplete()
Implement Google search suggestions feature into your scripts.
Script
Example
It uses httpQuery() for the http requests, and uriEncode() to encode the query string.
Thanks to Heresy & derRaphael for httpQuery() & uriEncode()
Cheers,
gahks
| Quote: | Parameters:
StringToComplete
ReturnValue
- CSV (default): Suggestions as a comma separated list
- Raw: Raw XML as returned by google
LanguageOfResults
- A standard two letter language code.
Google will return search suggestions related to the specified country.
