I want IntelliSense to work as described here.
Unfortunately, what I get is this:
As you can see, there are several differences.
false icon
false member info
no quick info
thousands of other list entries, I don´t need
This is a simple ASP.NET empty webproject in VS 2015. I have checked the options under Text-Editor -> JavaScript, which seems to be correctly.
This is probably being caused by ReSharper - I've actually had a better experience by disabling the ReShaper intellisense for JavaScript and letting it fall back to using Visual Studio.
To do so, go to:
ReSharper->Options
Expand the Intellisense group under Environment, choose General
Select "Custom IntelliSense"
Select Visual Studio in the drop down on the right for JavaScript
I've personally left all others set to ReSharper.
By toggling this setting between the two choices, I switch between seeing what you're describing in the question and what the blog post you linked to describes.

Hi, I'am new at js. I'am using VSCode. My problem is suggestions. I dont know it's true name maybe not suggestions maybe it's intellisense but When I pick an element with DOM and want to change it's style component, I wrote element.style but there aren't any suggestions showing up you can see in first two pics. But if I write element.style. there are some suggestion showing up. While on chrome dev console if I write elemnt.style

It shows me the style component. So how can I active it suggestions on visual studio code , like google console? I have some extensions is that cause problems?
extensions
VSCode is using static code analysis to try and guess what the types of your variables are. It has to do this because JavaScript is dynamically typed, so there is no way to be certain of the type of any given variable while you're writing the code. The JavaScript plugin for VSCode uses various heuristics to try and prove useful feedback.
Chrome actually evaluates the expressions you're typing as you type them, against a real DOM and JS runtime, and provides accurate feedback by reflecting on the value of each expression.
You can't make VSCode's static analysis behave like Chrome's dynamic reflection. They are very different systems, and this is a fundamental limitation of code-completion/intellisense for dynamic languages.
My question simply is:
I can't show any definition when hover on my specially my javaScript code
even by hovering or pressing ctrl+k or ctrl+space
I tried my ways but I can't reach this point
Installing the Visual Studio IntelliCode extension will fix that.
But even with that installed, since JavaScript is a loosely typed language, things like variables will just show any when you hover over them.
Installing IntelliSense removed this issue for me.
I have a bizarre issue where a websites JavaScript files are missing many of the editor functions such as:
handles around code blocks; buttons that allow collapse/expansion
correct line breaks; when pressing enter the cursor goes to the next line but first character position rather than nested per previous line
Keyboard shortcuts missing
Intellisense missing
The dotted line showing the start/end of a nest
and various others.
What I did to get to this:
I have a website in a solution, call it solution A and the JavaScript editing is normal.
This website is going to be moved into a new solution along with other projects.
I created a new empty solution (solution B) and added some solution folders.
I copied the website (via windows exploroer) from solution A to solution B.
Modified the namespace within the csproj file using notepad
Added this website as an existing project to solution B
Performed a find/replace through the code to adjust the namespace to the new one set in D above.
Now when I open my JavaScript files I get none of the functionality listed above.
I have verified that the Text Editor / Javascript/Typescript options are good.
The 2 images below are from copies of the same file in different solutions both running on Visual Studio 2017. The images demonstrate the lack of the collapse/expand button and the dotted lines. Interestingly, all color is correct.
Any ideas what might cause this?
Good JavaScript
Bad JavaScript
After some digging around a colleague found this link talking about a very similar issue - JavaScript intellisense still not working
One of the comments mentioned disabling the 'Language Service' function.
I did this, and sure enough all functionality has returned.
I am not going to mark this as an answer because i've had to disable one thing to cure another. This is just what i have had to do to get JS to edit correctly.
What I am doing right now us updating Visual Studio. It's currently 15.0.26430.4 and 15.4.27004.2002 has just been released. With any luck this resolves the issue.
UPDATE
After updating Visual Studio all is working correctly. Can only assume there was an issue with the Language Service.
I've got Web Essentials 2.5.3 installed in Visual Studio 2013 and the code folding feature works fine for function declarations but fails to show expand/collapse icons for object literals and array literals. Its driving me nuts and I can't seem to find anything in the Web Essentials settings to control these settings.
Has anyone encountered this issue or know of a solution?
I have the same issue. But I have found a work around for this, follow these 2 steps
1.select code snippet you want fold.
2.right click on selection, go to outlining Hide Selection. Short cut: (Ctrl+M, Ctrl+H)
This will work for you.
How can I simply get in this little popup (code completion) all possible methods/functions given when I type window.(blablabla).
Because if I type window. there is no "event" method for example.
In NuSphere there are all methods been listed.
Please differentiate between JavaScript and DOM code assist. There are many questions/answers here about this but it's ambiguous which of these two they refer to. None, I've seen, particularly claims to have found a solution for DOM and most mentions Aptana as standalone IDE or Eclipse plugin for solution.
For reasons outside the scope of this question I use Eclipse Indigo (3.7.2) and got this working w/o Aptana. This solution probably depends on the JavaScript Development Tools plugin.
First in the Navigator pane right click the project and hover the Configure option. Select Convert to JavaScript project or Add JavaScript Support.
Open project properties and a JavaScript item should appear in the left hand side list of configuration options. Expand and select Include Path. In the Libraries tab on the right you will see ECMA Script and ECMA 3 Browser Support. Switch to the Global Supertype tab and tick the ECAM 3 Browser Support checkbox. Restart Eclipse.

However in my case this last option didn't seem to work (when selected 'window' as global supertype, below the list got 'Window() null') and window. didn't bring results but document. and all other JS globals did. (So I could say for e.g. var w = document.defaultVeiw; and w. did bring up desired list.)
