一些小笔记

 getFields: function(text) {
        try {
            var fields = [];

            var matched = text.match(/{{[A-Za-z0-9_\(\)]+}}/g);
            if (Array.isArray(matched)) {
                for (var idx = 0; idx < matched.length; idx++) {
                    fields.push({
                        ‘origin‘: matched[idx],
                        ‘name‘: matched[idx].replace(/{{|}}/g, ‘‘)
                    });
                }
            }

            return fields;
        } catch (e) {
            iAuto.Logger.error(e.stack);
        }
    },

解析一段数据，用正则过滤一个数组的有效数据。

 getCurrentTime: function() {
        try {
            var date = new Date();
            var dateStr = ‘‘;

            dateStr = dateStr + (date.getMonth() + 1);
            dateStr = dateStr + ‘/‘ + date.getDate();
            dateStr = dateStr + ‘/‘ + date.getFullYear();
            var hours = date.getHours();
            var minutes = date.getMinutes();
            var seconds = date.getSeconds();
            if (hours > 12) {
                dateStr = dateStr + ‘ ‘ + (hours - 12);
            } else {
                dateStr = dateStr + ‘ ‘ + hours;
            }
            minutes = minutes >= 10 ? minutes : ‘0‘ + minutes;
            seconds = seconds >= 10 ? seconds : ‘0‘ + seconds;
            dateStr = dateStr + ‘:‘ + minutes;
            dateStr = dateStr + ‘:‘ + seconds;

            if (hours >= 12) {
                dateStr = dateStr + ‘ PM‘;
            } else {
                dateStr = dateStr + ‘ AM‘;
            }

            return dateStr;
        } catch (e) {
            iAuto.Logger.error(e.stack);
        }
    },
