Leveraging server-side functionality with JavaScript

Recently, I have been enhancing my ASP.NET project by incorporating more JavaScript and AJAX functionality. In the process, I have adjusted parts of my HTML to be generated using JavaScript. However, this modification has made it challenging for me to access the values stored in my local resource files.

In my project's structure, each page or user control has its own local resources and corresponding .js files.

I am seeking a straightforward and elegant solution that would allow me to utilize these local resources in JavaScript seamlessly. Ideally, I envision a method that can take a file like myfile.js, parse it based on the current language settings, and generate an output such as myfile.en.js

UPDATE

Here is how I envision the process:

<script src="../message.js"></script>
function showMessage(){
alert(GetLocalResource("AlertMessage"));
}

Answer №1

Absolutely! Develop a custom Controller or ApiController to access resources stored in your directory or resx file.

If you're working with a resx file, utilize the ResourceManager class.

There are numerous tutorials available online that outline the fundamental structure. Take a look at this one as an example: Show image data from database in asp mvc. This approach can be applied not only for images but for any type of files.

You have the flexibility to customize how incoming parameters, such as filename, are handled and can perform post-processing actions if necessary. Additionally, setting specific HTTP headers for caching purposes is also an option.

Answer №2

In my experience, I have discovered that transforming RESX files into JSON files and then integrating them into client-side JavaScript yields positive results.

Given that RESX files are in XML format, leveraging LINQ-to-XML will allow you to convert each node into a key and each value into a corresponding key value:

{ "myLabel": "hello world!" }

The challenge lies in effectively loading the appropriate resources based on the user's cultural preferences. By following a naming convention such as MyResources.en-US.json, you can dynamically concatenate the culture information from a cookie like so:

"MyResources." + cultureCookieValue + ".json"

To streamline the resource loading process, leveraging jQuery can be highly beneficial:

$.getJSON("/JsonResources/MyResources." + cultureCookieValue + .json").done(function(resources) {

  var myLabel = resources.myLabel;
});

This serves as a basic outline, but further development could involve creating abstractions for easier access to these resources within your client-side code.

Tip: Consider implementing a system to automatically convert RESX files during the build process using MSBuild!

If you're interested in generating minified JavaScript dynamically, creating your own Http Handler is a great option. You could also consider adding functionality for language translation, allowing for both minification and translation of files on the fly.
