How to read a properties file in javascript from project directory?

Question

I\'m building a Chrome Packaged App. I want to put the script configuration if a config file in a resource directory and on startup want to read that by Javascript.

It is pretty simple with JSF, but you will have to modify the HTML file every time you need a new parameter to be read from JavaScript. My property file (config.properties) in project directory has the following parameter as a key value pair.

parameter.key=parameter.value

The property file name is configured in faces-config.xml

    
        com.example.project.properties.config
        configuration
    

Therefore, you can use a property value in a hidden input inside the HTML file.

And from JavaScript function, use the following line to read the parameter value.

var parameter_value = document.getElementById("parameter_key").value;

Enjoy your day..!!!
