bootstrap typeahead获取结果数据源结果出现？

Question

i am not getting any results when i search.

<input type="text" class="span1" id="tag_field" data-items='4' data-provide="typeahead" data-source='[<?php echo json_encode($groups); ?>]' >
<?php echo json_encode($groups); ?>

when i echo out json_encond($groups) it appears in this format

{"35":"biology","37":"economist","33":"programmers"} 

if i type in the data source using this format i do get results.

 data-source='["Alabama","Alaska","Arizona"]'>

I think the Typeahead plugin is expecting an Array of Strings as the data-source. Your json_encode is creating an Object and you're just wrapping it in an array when you echo it.

You want something like this:

<?php
$groups = array("biology", "economist", "programmers");
?>

<input type="text" class="span1" id="tag_field" data-items='4' data-provide="typeahead" data-source='<?php echo json_encode($groups); ?>'>

You can use the array_values() function in PHP to ensure your $groups is a basic numerically indexed array.
