一、原生JavaScript實(shí)現(xiàn)字符串長度截取

二、原生JavaScript獲取域名主機(jī)

三、原生JavaScript轉(zhuǎn)義html標(biāo)簽

四、原生JavaScript時間日期格式替換

Date.prototype.Format = function(formatStr) {

var str = formatStr;

var Week = ['日', '一', '二', '三', '四', '五', '六'];

str = str.replace(/yyyy|YYYY/, this.getFullYear());

str = str.replace(/yy|YY/, (this.getYear() % 100) > 9 ? (this.getYear() % 100).toString() : '0' + (this.getYear() % 100)); str = str.replace(/MM/, (this.getMonth() + 1) > 9 ? (this.getMonth() + 1).toString() : '0' + (this.getMonth() + 1));

str = str.replace(/M/g, (this.getMonth() + 1));

str = str.replace(/w|W/g, Week[this.getDay()]);

str = str.replace(/dd|DD/, this.getDate() > 9 ? this.getDate().toString() : '0' + this.getDate());

str = str.replace(/d|D/g, this.getDate());

str = str.replace(/hh|HH/, this.getHours() > 9 ? this.getHours().toString() : '0' + this.getHours());

str = str.replace(/h|H/g, this.getHours());

str = str.replace(/mm/, this.getMinutes() > 9 ? this.getMinutes().toString() : '0' + this.getMinutes());

str = str.replace(/m/g, this.getMinutes());

str = str.replace(/ss|SS/, this.getSeconds() > 9 ? this.getSeconds().toString() : '0' + this.getSeconds());

str = str.replace(/s|S/g, this.getSeconds());

return str
