I have a project I am working on at work that is ASP.NET in TFS. I have checked out the solution and have made some adjustments to the code behind with no issues. When I try to add JQuery and a Javascript file to the project, it does it fine in Visual Studio 2012. But when rebuilding and running it won't execute the javascript code. It's like it ignores it. When I put breakpoints in the Javascript file I get the message 'The breakpoint will not currently be hit, no symbols have been loaded for this document'. I simply cannot get the web page to acknowlegde either the JS file, or the JQuery file.
(And yes, I have scoured StackOverflow.com and tried all the suggestions mentioned)
Any suggestions appreciated!

I have found the settings in Visual Studio Code to enable type checking for JavaScript in JS files. Such that: Bad code is highlighted and it also shows the reason why it's bad code
This behavior does not occur for JavaScript code in Vue files. I have searched through all the settings in Visual Studio Code. I have scoured the internet for any extension that can do this for me to no avail.
How can I make my Vue files type-check the JavaScript in them?
LOL. I found the answer.
All I had to do was add //#ts-check directly underneath the script tag and type checking was enabled.
So HAPPY!!!
Thank you, everyone, for your input
For best results I'd suggest starting a new project using vue-cli and selecting the options for TypeScript and ESLint. You'll also need the ESLint extension for VS Code.
Here's a helpful blog post showing the parts of this process.
Once you have a nicely working setup with the clean project, then move the code over. I suggest this because getting all the config right can be a mess with an existing project.
I am trying to find the way to debug javascript code inside the php file. I have a lot of javascript code embedded inside the php file.
I can debug php code using netbeans with the help of XDebug. I can also debug javascript separately inside html or js file with browser like chrome or firefox.
What I want is to debug javascript code inside the php file if it is possible. I am sure a lot of people will be using javascript embedded with php file. I don't like it personally, but I have to work it on. I know I can write the code separately in js file and then can debug with browsers, but it's lot of code, take time for the separation.
Can anybody here suggest me a way if it's possible what I am asking.
Debug Javascript in netbeans 7.4 inside PHP project
https://netbeans.org/kb/docs/php/debugging.html
https://confluence.jetbrains.com/display/PhpStorm/Debugging+PHP+and+JavaScript+code+at+the+same+time+in+PhpStorm
https://blog.jetbrains.com/phpstorm/2014/06/debugging-php-and-javascript-code-at-the-same-time/
IMHO, without even looking it up, i don't think that it is (nor should) be feasible.
Here's why:
Your PHP gets processed on the server side, that's when XDebug kicks in and enables you to breakpoint all your PHP code. Then the server output gets to the client, that's when the actual JS is processed inline in the parsed HTML. Which means you would have to intercept the HTML in some way, parse it, detect eventual inlined JS scripts... and set your breakpoint(s) at that time (yes on each run), then output to client, which parses the HTML yet again to render it and process eventual breakpoints. It would be a tedious process and even more tedious to get to work i guess and that is why nobody even tried making an extension for that.
To my knowledge, inlined JS is also a lot harder to debug and i never saw an actual setup that would allow breakpointing embedded tags in a static HTML document directly from the IDE, which would've been somewhat a little easier to achieve than breakpointing JS in PHP...
Your best shot i guess would be to externalise your JS in separate files and only hard code <script src="path/to/your/app.js"></script> in your PHP templates, which indeed would be much more comfortable to work with on the long run anyways.
Then you would be able to breakpoint all the stuff in app.js, plus have an actual front-end architecture, syntax-highlighting, impress your boss, make your life a lot easier, the world a better place, etc.

Edit: seems like setting JS breakpoints in static HTML tags is feasible in Visual Code for example -> https://github.com/Microsoft/vscode-chrome-debug/issues/122
I don't know if I am late, but, I came across the following website and was able to setup the debugger for Javascript and PHP which supports to debug embedded JavaScript in PHP scripts.
source: https://abcmemo.com/2017/04/20/debug-php-and-javascript-in-visual-studio-code/
The website uses PHP.exe as a web service.
It is also possible to use IIS, Apache or others.
Requirements:
IDE: Visual studio code
Extension: PHP debug
Extension: Debugger for (Chrome, Firefox or Edge)
Xdebug set in php.ini
Extension in browser (optional): PHP xdebug if you want to debug on trigger.
You need to have two debuggers running at the same time one for PHP and one for JavaScrpit.
PHP sample
JavaScript sample
I worked with a lot of wordpress templates where I had to deal with some js inside my php files. Assuming that you can run your code on a server, you can easily debug your output in dev tools in chrome (if using chrome). Chrome also allows for setting of breakpoints so you can go line by line, and since your browser ultimately runs the js, you can monitor your code behavior without dealing with the php. That was my main way of dealing with this issue.
I also recommend separating as much js as possible into separate files in your assets folder. Depending on your project, you rarely have to inline your code, In my opinion it's messy to include a lot of JS right in your php, unless you use onclick="" or onchange="" attributes (which can also be handled with event listeners.
Aside from that, console.log() the crap out of everything.
I helped my self with the following steps if it could help any body else
Note:- If your rendered code is inline specific to java-script then it would hard to debug like this.
Run the required page of your application using browser like chrome, edge etc
Open the inspection page by pressing f12 or (Ctrl+Shift+I), Or you can right click on the page see the option for the inspection and click on it.
Goto sources and double click on the source file(this will be probably your php file).
If code not loaded then reload the page by pressing f5 or Ctrl+R, you will see your java-script code there embedded with the html after rendering, then you can put the break point wherever you want and debug through the browser tools(you can see some buttons there to guide you about debugging like step-over,step-into etc).
You will also see errors there regarding java-script,
Actually I am a big fan of Google Chrome DevTools but it is very vast area for learning. I don't know much about it. I know how to out debug point, searching (Ctrl+Alt+F) and debugging, etc. basic things.
But in one of my project (its in asp.net MVC), it is requesting different views in Ajax request and in that views there are some js loading. I want to debug them but I am not able to. Actually I don't know where can I see them - especially the JS which is load after ajax call (its not inline javascript but a separate js files).
A workaround I found is - if I put 1 "debugger;" in that js file then it opens with some VM3012 or similar name with different numbers. Then only I can see the files. But I can not put debugger when I publish the code.
Any body knows then please help.
Thanks a lot for reading.
EDIT
as per first answer, I have tried but I can see that option "Open in Source panel" for normal JS file. But in my case my request is passing some query string to the js file like assets/components/utility/mycustom.js?_=1528282662460 and I am not able to see that option for such request. This help is appreciated but need more.
I know it's been 3 years but...
You can name the piece of javascript code inside the dynamic loaded file by adding the following above the code:
//# sourceURL=my-file-name.js
By doing it, that piece of javascript will be available in the file tree of the source panel and can also be found by the DevTools' CTRL+P shortcut.
Go to the network tab of the dev tools. You can filter by js files to help you find the file you need. Right click on the file you want and select Open in sources panel. You should now be able to put the breakpoint where you like as you are used to.
I'm using Primefaces 5.1. When I load my web page, go into the Firefox debugger and look into the javascript, I see that it has loaded some javascript (Primefaces.js.jsf to be precise) which is part of Primefaces 5.0 version. Now, I have taken care to delete all the references of 5.0. But still I get the same result.
So, my question is- when a web page is loaded, and we see the javascript files loaded, how do we know where a particular script file is being retrieved from?
P.S: I'm not the one who wrote the code to include this js. it is part of the framework. So, I have no control over where it is being accessed from. All I can do is if I know the path of the file, I can modify it to suit my needs.
I have deleted the history/cache/Temporary files and also loaded the page using Ctrl + F5. Didnt help.
Found out why the project was still referring to PF5.0. The primefaces-5.0.jar still co-existed with primefaces-5.1.jar in the WEB-INF/lib directory of the project residing in the glassfish directory 'glassfish3\glassfish\domains\domain1\eclipseApps'.
I have a project that just happens to be MVC and in Visual Studio 2010. (I don't know if that has anything to do with it, but I'm just trying to be specific in the problem) The issue is that when I build it it is auto minimizing the javascript and as such makes it really hard to debug.
I have looked at the build events and there are none.
I have looked for any vs extensions that could do this and I don't see any out of the ordinary.
I have edited the project file just to make sure nothing was hidden in it.
Does anyone have any ideas as to why this behavior could be happening?
Does your site master just reference a minified js file instead of your development version of the js file?
Thanks to all for trying to help. I found it though. Our company has created an HttpHandler that was configured in the web.config that causes this functionality. I thought I had looked everywhere, but missed this as I was going through it.
