Question

我在jsfiddle http://jsfiddle.net/93pEd/174/上看到了这段代码。我决定修改我的代码项目，因为它有点类似。我在原点（左）转换为（右）
时添加了另一个下拉列表

请大家帮忙解释如何转换时间并将其放在输入文本字段中这是我添加/编辑的代码附：我没有改变javascript代码。

＆＃13;

$(function(){
    $('.location').each(function() {
        var timeZone = $(this).data('tz');
        
        var now = moment().tz(timeZone).format('HH:mm');
        $(this).append( now );
    });
});

＆＃13;

<select>
<option><span class="location" data-tz="Africa/Tripoli">Tripoli: </span></span><br /><option>
<option><span class="location" data-tz="Europe/London">London: </span><option>

$(document).ready(function(){

    // get Bombay time
alert(calcTime('Bombay', '+5.5'));

// get Singapore time
alert(calcTime('Singapore', '+8'));

// get London time
alert(calcTime('London', '+1'));
});


function calcTime(city, offset) {

    // create Date object for current location
    d = new Date();
   
    // convert to msec
    // add local time zone offset
    // get UTC time in msec
    utc = d.getTime() + (d.getTimezoneOffset() * 60000);
   
    // create new Date object for different city
    // using supplied offset
    nd = new Date(utc + (3600000*offset));
   
    // return time as a string
    return "The local time in " + city + " is " + nd.toLocaleString();

}
