您的要求似乎微不足道，还有更多吗？这是显而易见的答案：

function formatTimestring(s) {

var b = s.split(/[\\/:]/);

return b[2] + b[1] + b[0] + \'T\' + b[3] + b[4] + \'00\' + \'Z\'

}

alert(

formatTimestring(\'08/09/2010:12:00\') //20100908T120000Z

);

如果要从日期对象或\“ now \”生成请求格式的UTC字符串，则：

/*

* Return a date string as yyyymmddThhmmssZ

* in UTC.

* Use supplied date object or, if no

* object supplied, return current time

*/

var dateToUTCString = (function () {

// Add leading zero to single digit numbers

function addZ(n) {

return (n<10)?\'0\'+n:\'\'+n;

}

return function(d) {

// If d not supplied, use current date

var d = d || new Date();

return d.getUTCFullYear() +

addZ(d.getUTCMonth() + 1) +

addZ(d.getUTCDate()) +

\'T\' +

addZ(d.getUTCHours()) +

addZ(d.getUTCMinutes()) +

addZ(d.getUTCSeconds()) +

\'Z\';

}

}());

如果您想使用mm-dd-yyy hh：mm [：ssam / pm]：

// input format: mm-dd-yyy hh:mm:ss[ ]am|pm

function timeStringToUTC(s) {

// Deal with trailing am/pm if present

// Probably should trim leading spaces here too

var isPM = /pm\\s*$/i.test(s);

s = s.replace(/\\s*pm\\s*$/i,\'\')

// Split the string on any of -, space or :

var b = s.split(/[- :]/);

// Add 12 to hour if is pm

if (isPM) {

b[3] = +b[3] + 12;

} else {

// Add leading zero if hours less than 10

b[3] = (b[3] < 10)? \'0\' + +b[3] : b[3];

}

// Add leading zero to minutes if < 10

if (b[4] < 10) b[4] = \'0\' + +b[4];

// If seconds not supplied, set to 00

if ( !/^\\d\\d?$/.test(b[5])) {

b[5] = \'00\';

} else {

// Add leading zero if seconds less than 10

if (b[5] < 10) b[5] = \'0\' + +b[5];

}

// Generate date object, call dateToUTCString to return

// UTC date string

return dateToUTCString(

new Date(b[2] + \'/\' +

b[0] + \'/\' +

b[1] + \' \' +

b[3] + \':\' +

b[4] + \':\' +

b[5]

)

);
