Javascript 创建GUID和判断字符串是否为GUID格式

var GUID = GUID || {};

GUID = {

generateGuid: function () {

function S4() {

return (((1 + Math.random()) * 0x10000) | 0).toString(16).substring(1);

}

return (S4() + S4() + "-" + S4() + "-" + S4() + "-" + S4() + "-" + S4() + S4() + S4());

},

 

isGuidFormat: function (guid) {

var reg = new RegExp(/^[0-9a-zA-Z]{8}-[0-9a-zA-Z]{4}-[0-9a-zA-Z]{4}-[0-9a-zA-Z]{4}-[0-9a-zA-Z]{12}$/);

if (reg.test(guid)) {

return true;

}

return false;

}

}
