问题
I have Visual Studio 2012 installed on my laptop and desktop. On my desktop PC, the JavaScript intellisense is not working. For any method it pulls up (even standard JavaScript calls) I receive the message, "Intellisense was unable to determine an accurate completion list for this expression".
I've tried all of the suggestions from the other posts and tried everything I could find on Google. Nothing has worked. It isn't about not having JQuery Intellisense. I don't get even basic JavaScript Intellisense.
Edit:
The objects in the above images are simple strings, yet I don't get any help from the Intellisense.

I had the same problem: in Visual Studio 2010 I was used to add a reference in my javascript files, at the top, like this:
/// <reference path="/scripts/jquery-1.7.1-vsdoc.js" />
With the new Visual Studio 2012 this was not working anymore, I looked around and found the solution to put the reference in /scripts/_references.js I did so, not working.
What I was doing wrong was that I was referencing the vsdoc.js file, or at the moment of writing, nuget downloaded jquery 1.9.1 package, reference to jquery-1.9.1.intellisense.js which is WRONG.
The correct reference (if using the /scripts/_references.js file) is:
/// <reference path="/scripts/jquery-1.9.1.js" />
(NOT the .intellisense.js or the -vsdoc.js file).
For the global solution to work on all your projects: copy all the jquery files (main, minified, map, and intellisense one, to be sure) in C:\Program Files (x86)\Microsoft Visual Studio 11.0\JavaScript\References (adapt the path if you installed Visual Studio 2012 somewhere else) and in Visual Studio, under Tools > Options > Text Editor > Javascript > Intellisense > References > Add a reference to jquery-1.9.1.js (again, NOT the vsdoc or intellisense file, but the main one) as explained in the solution by denas (but it was not clearly said not to point the vsdoc/intellisense file).
Hope this helps.

Many things can cause problems like this, but I usually follow these steps to troubleshoot it.
- close visual studio and restart
- reboot windows and start visual studio again
- have another developer load your project and test it
- create a bare bone project and test with all stock javascript references
- reset IDE
- run VS in safe mode and test your project
- uninstall and reinstall vs
I usually resolve most of the VS problems at step 3 or 4, and sometimes 5.

If you've installed VS on anything other than the C Drive this will happen.
In Visual Studio, under Tools > Options > Text Editor > Javascript > Intellisense > References
Add references to the same .js files that exist in the list but pointing to the new path where you have VS installed
eg - G:\Program Files\Microsoft Visual Studio 11.0\JavaScript\References.libhelp.js
There are 5 of them
After this go to Edit> Intellisense > Refresh external references

I fixed the same problem by right-clicking the file in Solution Explorer and choosing Open With and then choosing Web Form Editor if you're editing a Web form or Source Code (Text) Editor if you're editing a JavaScript file.

In visual studio 2012,
Using this solution https://github.com/jmbledsoe/angularjs-visualstudio-intellisense.
Make sure put ng, ngCookies modules into required fields. For example: var module = angular.module("demo", ['ng','ngCookies']);

An excellent article by Mads Kristensen helped me fix the JavaScript Intellisense issue.
Triple-slash references look like this and can be added to the top of any .js file or in /scripts/_references.js file
/// <reference path="../app/respond.js" />
