属性过滤器定义
groot.filter(
{
"d": function (value, format) {
if (!value) return;
if (!format) format = "yyyy-MM-dd";
switch (typeof value) {
case "string":
value = new Date(value.replace(/-/, "/"));
break;
case "number":
value = new Date(value);
break;
}
if (!value instanceof Date) return;
var dict = {
"yyyy": value.getFullYear(),
"M": value.getMonth() + 1,
"d": value.getDate(),
"H": value.getHours(),
"m": value.getMinutes(),
"s": value.getSeconds(),
"MM": ("" + (value.getMonth() + 101)).substr(1),
"dd": ("" + (value.getDate() + 100)).substr(1),
"HH": ("" + (value.getHours() + 100)).substr(1),
"mm": ("" + (value.getMinutes() + 100)).substr(1),
"ss": ("" + (value.getSeconds() + 100)).substr(1)
};
return format.replace(/(yyyy|MM?|dd?|HH?|ss?|mm?)/g, function () {
return dict[arguments[0]];
});
}
}
)
上面是内置的时间过滤器的定义；groot.filter 为属性过滤器扩展接口
