Config File for IDE

Does anyone know how to load a config file at an IDE's run time? I have many IDE scripts the problem is that suppose my variable for my URL, username and password change? I then have to manually update many files does anyone know if there is a way to load this type of config by using extensions? thanks

I'm sure there is a more efficient way to do this function, but you can have a function like this that returns the text you want. Put it in your user-extension file and just edit the function name(EnterUserName) and the "username" text that you want and you should be good to go. Hopefully this helps.

Selenium.prototype.doEnterUserName = function(locator, text) {
// All locator-strategies are automatically handled by "findElement"
var element = this.page().findElement(locator);

//This will create what you want to type into a field. In this case, your username
var valueToType = "username";


// Replace the element text with the new text
this.page().replaceText(element, valueToType);
};
