Use square bracket notation to use a string literal or value from a variable to reference a property:

function dipslayItmes ( language )
{
    ...
    for ( i = 0; i < JSONobj[language].item.length; i++ )
       document.write( JSONobj[language].item[i] );
    ...
}

Whenever you do foo.bar, you usually can do foo["bar"]. However, not only can you put strings in the brackets, you can also put other expressions. Therefore, you can use this:

function displayItems(language) {
    ...
    for(var i=0; i<JSONobj[language].item.length; i++) {
        document.write(JSONobj[language].item[i]);
    }
    ...
}
