Thanks dude, it works now (:

by Wolf4e | July 10 2015

After the last update, the notification on top of the editor is not shown - VS 2013. But still - great tool.

Hi Wolf4e!

Probably the error is not more considered as critical. With change of parsing engine there was changed whole logic of error handling.

Please try some obvious malformed javascript.

Could you please post an issue to github with more details?

Killed the performance of VS 2013 for me. Didn't realize how bad it was until I ran into web.config issues where there was a localdb connection string in machine config that kept creating an aspnetdb.mdf in my solutions under App_Data. Removed it from machine config and this extension started crashing on VS startup. Removed this extension and the localdb connection string and now my VS runs about 100x faster and starts up much quicker.

I suppose you just picked wrong extension page to write your negative feedback.
Javascript parser has to do nothing with any project web.config files and of course it is not performing any database connections.
All what it is responsive for is parsing javascript in background. That of course is not very cheap operation but it is sure isn't the "performance killer"

Absolutely fantastic! A must for JavaScript developer on VS 2013

Good addim, very useful.

Handy even if you are using Web Essentials already. An ignore list for errors would be great though.

I like you extension showing the error on top of editor but it makes the editor to respond slowly when we type text. please please fix it.

Such a well implemented extension! Why couldn't Visual Studio do this? Great job.

by ahmd0 | September 19 2014

I've been looking for something like this for a while. Amazing plug-in. Thanks to developer! Editing large JavaScript files without this plug-in is virtually impossible.

PS. It really beats me why neither native Visual Studio nor other JS editors like Dreamweaver provide any means to navigate among JS functions and global variables. This plug-in makes it a breeze!

by virtualadrian | September 13 2014

Fantastic plugin!!!! Highly recommend it if you're trying to clean up your scripts. I use this and a "New Solution Explorer" from my scripts folder and I can find my way around much easier.

Great addin, saves a lot of headache when searching for typos. The tree function is also very useful. The author deserves a donation! How can I do it? Thanks Oleksandr!

I found this tool that help me coding javascript more quickly. Thanks you for your good extension

Awesome. Why Microsoft the 'let's all program in javascript' company is not providing this OOB is beyond me.

by napoleonss | February 17 2014

Very handy.

by eric_weller | January 10 2014

Awesome tool! I have been doing a lot of JavaScript development and this tool provides the functions needed to quickly navigate large files.

by CmBonn | November 07 2013

I've just installed this. I'm hoping not to experience the crashes people have been talking about because even in 5 minutes of use, I can see this is going to save me a TON of time. For complex JS applications, this would seem to be invaluable. Being able to see the code structure is amazing. Great work on this!

  • Parser Errors but there is nothing wrong that I can see
    3 Posts | Last post July 09, 2015
    • In Visual Studio 2013 I created a C# Web Application Project. I'm getting 3 Javascript Parser errors but they are not even Javascript code on those lines.
      
      Says syntax error on the below two lines.
      <!DOCTYPE html>
      
      <li><a runat="server" href="~/ShoppingCart" id="cartCount">&nbsp;</a></li>
      
      Semicolon Expected error on the line below.
      <p>&copy; <%: DateTime.Now.Year %> - Wingtip Toys</p>
      
      Any Help would be most appreciated.

    • Forgot to mention it is in the Site.Master page.
    • You can disable Javascript parser for .master pages in options.
  • Pop-up cut off

    • I'm using VS 2013 on Win7 64bit. Once in a while this extension pops up a message saying "Help improve JavaScript Parser extension". This popup is cut off at the bottom (unfortunately I cannot post a screenshot here), and to dismiss it you need to manage to click barely visible top of the buttons, or use enter for default action. Please fix.
      
    • Probably you use some kind of multi-monitor configuration. 
      I believe that this popup could be moved as usual window.
  • ES6 Support
    3 Posts | Last post July 09, 2015
    • Any plans on adding support for ES6 keywords and features?
    • Hi Maksim,
      Currently I am in progress of moving parsing engine from Microsoft JScript compiler (which is kinda old) to new JInt parser (which contains C# port of Esprima parser). This is going to provide a lot of improvements, bugfixes and of course ES6 support.
    • This is finally happened. A lot of improvements have come with 4.0 release.
      
  • Any way to copy text from Javascript Parser window?
    2 Posts | Last post May 16, 2015
    • Is there any way to copy and paste text from the Javascript Parser window?
      
      It would be really useful to be able to do this in order to document code structure at a function level, monitor changes over time, etc.
      
      I can do a screengrab, but it's not as useful.
    • Hi Mambero,
      No, currently there is no way to copy list of functions.
      I've just moved project to github (https://github.com/megaboich/jsparser), you can create issue there.

    • Hi, I installed this hoping it would help with syntax issues in an MVC view. I cannot find this in Visual Studio anywhere nor doe it seem to work with an MVC view. 
      
      Can anyone enlighten on if this is possible?
    • If you're having challenges finding the JS Parser window: Go to View -> Other Windows -> JS Parser and it will show up. When you're viewing a JS file you'll see the outline. 
  • "Syntax error" on "debugger;"
    3 Posts | Last post August 22, 2014
    • I am a heavy user of "debugger;". This is the conventional codified breakpoint methodology. I don't appreciate being told this is a syntax error.
    • I second that motion!
    • Hey guys,
      I had the same "issue" but find the way to disable it.
      Go settings > There is a checkbox [X] Do not treat "debugger" keyword as error.
      
  • Syntax Error on doctype
    2 Posts | Last post June 30, 2014
    • Whenever I open a .ASPX Masterpage for some reason the JavaScript parser gives me a syntax error with the "<!doctype html>" tag.  I'm running VS 2012 update 4, and of course it's HTML 5.
    • Go into extension options and add the missing "master" extension to the partial ignore list:

      The default value for this list is kinda broken, with two entries for "aspx" and none for "master".

  • Tons of junk entries parsed
    1 Posts | Last post September 30, 2013
    • I've used in the past this extension, and was happy.
      I just installed it again, but the latest version generates high noise.
      
      It parses all jquery $( ... ) call, 
      it parses all jquery method, example: css>?, prop>?
      
      How can we turn this off?
