How to implement an autocomplete text input field

Hello,

I will like to implement an autocomplete text input field in my website but It doesn’t work.
I need a autocompletion for the city name.

I made the following staffs:

1°/ In my functions.php file:

wp_enqueue_script( ‘suggest’ );

2°/ In my js folder, I create this js file:

<script>
$(‘#suggest’).suggest(“town_list.txt”,{
onSelect: function() {
alert(“You selected: ” + this.value );
}
});
</script>

3°/ In my php page:

<input type=”text” id=”suggest” name=”keyword” />

BUT I DOESN’T RUN!!! I don’t know why? Does someone could help me please.

Best regards,

Gwen
