• javascript
• jquery
• load
• typeahead.js
• autosuggest

• check the network tab of developer tools(F12 > Network) to see if all your scripts are getting loaded correctly – wirey00 Commented Aug 4, 2014 at 13:51

Where did you get your tipeahead script? Looks like it relies on Underscore.js or Lo-Dash

We need more information anyway (stacktrace, how you load the typeahead script, and its content).

I got this error when I was referencing typeahead.bundle.js from the /src/ (source) folder of the bower package instead of the /dist/ (distribution) folder by mistake.

By pointing at the /dist/typeahead.bundle.js instead it works fine without the need to add Underscore.js or Lo-Dash manually.

If you look here you'll see the instructions for installing this library. The _ that it's missing is defined in bloodhound.js. You can see where it is defined in this file around line 6.

Try adding that link before your typeahead script and see if that fixes the problem.

This all may be included with the typeahead script you're loading, which would make my answer wrong, but try it out and see if that fixes it.

Edit: here is the definitions of _ in the github repo
