说组Array扩展是否包含元素属性:
//扩展函数(是否包含某元素)
Array.prototype.contains = function(e)
{
for(i=0;i<this.length;i++)
{
if(this[i] == e)
return true;
}
return false;
}
/*用法:
Array.prototype.contains = function(e)
{
for(i=0;i<this.length;i++)
{
if(this[i] == e)
return true;
}
return false;
}
/*用法:
var temp = [1,2,3,4,5];
var status = temp.contains(1);
*/日期格式化:
Date.prototype.formate = function(fmt){
var o = {
"M+": this.getMonth() + 1, //月份
"d+": this.getDate(), //日
"h+": this.getHours() % 12 == 0 ? 12 : this.getHours() % 12, //小时
"H+": this.getHours(), //小时
"m+": this.getMinutes(), //分
"s+": this.getSeconds(), //秒
"q+": Math.floor((this.getMonth() + 3) / 3), //季度
"f": this.getMilliseconds() //毫秒
};
var week = {
"0": "/u65e5",
"1": "/u4e00",
"2": "/u4e8c",
"3": "/u4e09",
"4": "/u56db",
"5": "/u4e94",
"6": "/u516d"
};
if (/(y+)/.test(fmt))
{
fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
}
if (/(E+)/.test(fmt))
{
fmt = fmt.replace(RegExp.$1, ((RegExp.$1.length > 1) ? (RegExp.$1.length > 2 ? "/u661f/u671f" : "/u5468") : "") + week[this.getDay() + ""]);
}
for (var k in o)
{
if (new RegExp("(" + k + ")").test(fmt))
{
fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
}
}
return fmt;
}
var o = {
"M+": this.getMonth() + 1, //月份
"d+": this.getDate(), //日
"h+": this.getHours() % 12 == 0 ? 12 : this.getHours() % 12, //小时
