I've been trying to use excel-builder.js library to generate and Excel file and download it automatically, just as done here.
Now, I must stress out that I'm rather new to front end development, otherwise I might have figured it out already...
Anyway, what I can't seem to figure out is what is this "downloader" in the example? download is required and downloader is used like magic, but for me it doesn't work (since I don't really know what to require).
Has anyone tried it successfully? Thanks in advance!
OK, sorry for the bother. As I stated, I'm new to this.
I found the relevant code, and like in other places, it has to do with creating an invisible form and submitting it.

I have a relatively simple task that I want to achieve, but I am totally stumped on how to achieve it. I want to create an HTML page that allows users to select a local JSON file. I want to pass the path to this local file to some Javascript code. Then I want to read that file using Javascript every time the file changes.
I've investigated a few different methods for achieving this. First, I tried just using Javascript. This worked great until I wanted to read the file multiple times as it was changing. Evidently there are security concerns that make this impossible.
Next, I investigated using Node.js to solve this problem. It has some file utilities that seem perfect, and it's server-side, which may help with the security issues. But using just Node, I couldn't figure out how to select a local file in HTML and pass the path to the Javascript code. From investigation online, it seems like Express.js would be useful.
So now I'm trying to use Node.js and Express.js. Now I can figure out the file name from an HTML form! But I can't figure out the path to the local file so that I can read it using the Node file utilities... From looking at similar questions online, it looks like everyone uploads files, then reads them. Is that what I have to do with Express? If so, is it possible for me to monitor changes to the original file, upload the file when those changes get made, then read the changed file? Is what I'm trying to do possible? If so, does anyone have any recommendations on libraries/modules to use? Thank you so much for any help - please let me know if I can be more clear about anything.
Javascript && doesn't work in Wordpress posts. I know it is better not to write Javascript in posts, but makes sense in this case. I think there are plugins that could make this work, but got to be a simpler way... I could avoid using AND in my code logic, but that would be a pain.
I've heard that \u0026 could do it, but can't get that to work for me. I've also heard that would work, but that doesn't work for me either. So I've done my research, but none of the solutions I've come across work.
Any other suggestions?
Thanks,
Sam
Javascript support in every page.If you want to apply javascript in single.php file.
you can put end of file using <script> // code </script>
But make sure your php tag is complete or not before start script tag.
I m using T4MVC in MVC project. My question is is there such a solution for external JS files ? Many times there need to use URLs or strings (to compare) in external JS files. A change in sting break application. Or please advice T4MVC can be used for same.
Highly appreciate your time, help and sharing.
Try T4MVCJS
We got it to work on a proof of concept project, However we managed to delete that project and cannot get it to work with any of our existing projects. Maybe you'll have more luck than us.
I just discovered a virus in my computer that uses a .js file to attack. I opened the file in notepad to check out the code, but it is completely encrypted. I can see some data that makes sense (such as bhynivmao.length!=4), but the majority of the file is filled with gibberish.
There is also an autorun.inf and even though I can see some of the shell \open\command, I am not able to figure out the rest of the gibberish that is present.
Looks like both the autorun and the .js file are obfuscated the same way. Can someone please help me to get back the readable code? I am really curious to know how this thing works.
Try using something like a JS beautifier:
http://jsbeautifier.org/
It will still keep the old variable names, but will definitely make the code more readable.
You might also consider using http://jsnice.org, which uses statistical analysis of code to identify variable names. It complements http://jsbeautifier.org well by altering variable names but not structure.
So guys I am working on a program to like download stuff using javascript. I hav written the following code:
function download()
{
alert("Hello");
var url='http://somesite/somefile.rar';
window.open(url,'Download');
}
The code is pretty easy, but is there some other way to download the file using javascript? Also having downloaded the file is there some way to store it locally in the location of our choice, like d-drive? I had come across the javascript file api while searching the web, is it any useful in my scenario? Please help.
Edit: Fixed code formatting
No, this isn't possible. It is up to the client where to save files, not you.
Through Javascript, you can only set the file name that you want, but would not be able to access the file system i.e. All the folders, etc..
