twitter bootsrap typeahead不起作用

Question

我做错了什么？

在控制台尝试了这一点，但typeahead不起作用。没有错误。

→ $("#to_folder_name").typeahead({"source": DS.folders_names_array}) 
← [<input type=​"text" data-provide=​"typeahead" id=​"to_folder_name" size=​"15" placeholder=​"Move to..."] 


→ DS.folders_names_array 
← ["hhhhhhh", "dddssss", "Root", "Default", "Archive", "Custom", "1A", "after SaveExistingLocation_Test", "Hanny", "ggggg", "ggg123", "new folder", "new folder2", "dddddd", "new folder4", "ggg"] 

→ $("#to_folder_name") 
← [<input type=​"text" data-provide=​"typeahead" id=​"to_folder_name" size=​"15" placeholder=​"Move to...">​] 

包括typeahead.js。
