如何在JavaScript中从这个日期对象生成月份的名称(例如:10月/ 10月)?
var objDate = new Date("10/11/2009");

当前回答
Date.prototype.getMonthName = function() {
var monthNames = [ "January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December" ];
return monthNames[this.getMonth()];
}
它可以被用作
var month_Name = new Date().getMonthName();

这是一种不依赖于硬编码数组并支持多个区域设置的方法。
如果你需要一个完整的数组:
var monthsLocalizedArray = function(locale) {
var result = [];
for(var i = 0; i < 12; i++) {
result.push(new Date(2010,i).toLocaleString(locale,{month:"long"}));
}
return result;
};
用法:
console.log(monthsLocalizedArray('en')); // -> ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
console.log(monthsLocalizedArray('bg')); // -> ["януари", "февруари", "март", "април", "май", "юни", "юли", "август", "септември", "октомври", "ноември", "декември"]
如果你只需要一个选定的月份(更快):
var monthLocalizedString = function(month, locale) {
return new Date(2010,month).toLocaleString(locale,{month:"long"});
};
用法:
console.log(monthLocalizedString(1, 'en')); // -> February
console.log(monthLocalizedString(1, 'bg')); // -> февруари
console.log(monthLocalizedString(1, 'de')); // -> Februar
经过测试,在Chrome和IE 11上运行良好。在mozilla上需要做一些修改,因为它返回整个日期。
Date.prototype.getMonthName = function() {
var monthNames = [ "January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December" ];
return monthNames[this.getMonth()];
}
它可以被用作
var month_Name = new Date().getMonthName();
这是另一个,支持本地化:)
Date.prototype.getMonthName = function(lang) {
lang = lang && (lang in Date.locale) ? lang : 'en';
return Date.locale[lang].month_names[this.getMonth()];
};
Date.prototype.getMonthNameShort = function(lang) {
lang = lang && (lang in Date.locale) ? lang : 'en';
return Date.locale[lang].month_names_short[this.getMonth()];
};
Date.locale = {
en: {
month_names: ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'],
month_names_short: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
}
};
然后,您可以轻松地添加对其他语言的支持:
Date.locale.fr = {month_names: [...]};
将名称存储在一个数组中,并根据月份的索引进行查找。
var month=new Array(12);
month[0]="January";
month[1]="February";
month[2]="March";
month[3]="April";
month[4]="May";
month[5]="June";
month[6]="July";
month[7]="August";
month[8]="September";
month[9]="October";
month[10]="November";
month[11]="December";
document.write("The current month is " + month[d.getMonth()]);
JavaScript getMonth()方法
只是扩展了许多其他优秀的答案-如果你正在使用jQuery -你可以做一些类似的事情
$.fn.getMonthName = function(date) {
var monthNames = [
"January", "February", "March",
"April", "May", "June",
"July", "August", "September",
"October", "November", "December"
];
return monthNames[date.getMonth()];
};
其中date等于var d = new date (somevalue)。这样做的主要优点是@nickf避免使用全局名称空间。
