我应该如何将javascript函数调用到kohana视图中？-howshouldicallajavascriptfunctionintoakohanaview?

i am having a simple kohana view, and a Javascript that makes a countdown of 30 minutes. I hava put the Javascript file into a directory /media m and its name is countdown.js . My problem is: how can i call that Javascript? Form the view? Or from the controller to be displayed in the view? and how exactly may i address in a controller or a view that js function or functions?

我有一个简单的kohana视图，以及一个倒计时30分钟的Javascript。我把Javascript文件放到目录/ media m中，它的名字是countdown.js。我的问题是：我怎么称呼这个Javascript？形成观点​​？或者从控制器中显示在视图中？以及我如何在控制器或js功能或功能的视图中寻址？

thank you

谢谢

the countdown js:

倒计时js：

var Javascript_countdown = function () { var time_left = 10; //number of seconds for countdown var output_element_id = 'Javascript_countdown_time'; var keep_counting = 1; var no_time_left_message = 'No time left for Javascript countdown!';

var Javascript_countdown = function（）{var time_left = 10; //倒计时的输出秒数output_element_id ='Javascript_countdown_time'; var keep_counting = 1; var no_time_left_message ='没有时间进行Javascript倒计时了！';

function countdown() {
    if(time_left <2) {
        keep_counting = 0;
    }

    time_left = time_left - 1;
}

function add_leading_zero(n) {
    if(n.toString().length <2) {
        return '0' + n;
    } else {
        return n;
    }
}

function format_output() {
    var hours, minutes, seconds;
    secOnds= time_left % 60;
    minutes = Math.floor(time_left / 60) % 60;
    hours = Math.floor(time_left / 3600);

    secOnds= add_leading_zero( seconds );
    minutes = add_leading_zero( minutes );
    hours = add_leading_zero( hours );

    return hours + ':' + minutes + ':' + seconds;
}

function show_time_left() {
    document.getElementById(output_element_id).innerHTML = format_output();//time_left;
}

function no_time_left() {
    document.getElementById(output_element_id).innerHTML = no_time_left_message;
}

return {
    count: function () {
        countdown();
        show_time_left();
    },
    timer: function () {
        Javascript_countdown.count();

        if(keep_counting) {
            setTimeout("Javascript_countdown.timer();", 1000);
        } else {
            no_time_left();
        }
    },
    init: function (t, element_id) {
        time_left = t;
        output_element_id = element_id;
        Javascript_countdown.timer();
    }
};

}();

}（）;

//time to countdown in seconds, and element ID Javascript_countdown.init(3673, 'Javascript_countdown_time');

//以秒为单位倒计时的时间，以及元素ID Javascript_countdown.init（3673，'Javascript_countdown_time'）;
