Simple language selector to apply language changes to a page

languageselector.js

$(document).ready(function(){
	// Set appropriate language by default
	if (localStorage.languageSelection) {
		if(localStorage.languageSelection == "spanish") {
			$(".spanish").show();
			$(".english").hide();
		}
		else {
			localStorage.languageSelection = "english";
			$(".english").show();
			$(".spanish").hide();
		}
	}
	else {
		// English language by default
		localStorage.languageSelection = "english";
		$(".english").show();
		$(".spanish").hide();
	}
});

function toggleSpanish() {
    if (localStorage.languageSelection == "spanish") {
    	// Already spanish...
    	return;
    }

    // Hide English translation
    $(".english").toggle();
    // Show Spanish translation
    $(".spanish").toggle();
    localStorage.languageSelection = "spanish";
}

function toggleEnglish() {
    if (localStorage.languageSelection == "english") {
    	// Already english...
    	return;
    }

    // Hide Spanish translation
    $(".spanish").toggle();
    // Show English translation
    $(".english").toggle();
    localStorage.languageSelection = "english";
}

can I use this to hide tweets from specific language ?
