使用 RGraph(HTML5) 绘制折线图（四）

先说说上文遗留问题，时间处理

Common.js
String.prototype.trim = function () {
    return this.replace(/(^\s*)|(\s*$)/g, "");
}

String.prototype.leftTrim = function () {
    return this.replace(/(^[\\s]*)/g, "");
}

String.prototype.rightTrim = function () {
    return this.replace(/([\\s]*$)/g, "");
}

String.prototype.chineseLength = function () {
    return this.replace(/[^\x00-\xff]/g, "**").length;
}

String.prototype.endsWith = function (str) {
    return this.substr(this.length - str.length) == str;
}

String.prototype.startsWith = function (str) {
    return this.substr(0, str.length) == str;
}

Date.prototype.format = function (mask) {
    var d = this;
    var zeroize = function (value, length) {
        if (!length) length = 2;
        value = String(value);
        for (var i = 0, zeros = ''; i < (length - value.length); i++) {
            zeros += '0';
        }
        return zeros + value;
    };
    return mask.replace(/"[^"]*"|'[^']*'|\b(?:d{1,4}|m{1,4}|yy(?:yy)?|([hHMstT])\1?|[lLZ])\b/g, function ($0) {
        switch ($0) {
            case 'd': return d.getDate();
            case 'dd': return zeroize(d.getDate());
            case 'ddd': return ['Sun', 'Mon', 'Tue', 'Wed', 'Thr', 'Fri', 'Sat'][d.getDay()];
            case 'dddd': return ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'][d.getDay()];
            case 'M': return d.getMonth() + 1;

            case 'h': return d.getHours() % 12 || 12;
            case 'hh': return zeroize(d.getHours() % 12 || 12);
            case 'H': return d.getHours();
            case 'HH': return zeroize(d.getHours());
            case 'm': return d.getMinutes();
            case 'mm': return zeroize(d.getMinutes());
            case 's': return d.getSeconds();
            case 'ss': return zeroize(d.getSeconds());
            case 'l': return zeroize(d.getMilliseconds(), 3);
            case 'L': var m = d.getMilliseconds();
                if (m > 99) m = Math.round(m / 10);
                return zeroize(m);
            case 'tt': return d.getHours() < 12 ? 'am' : 'pm';
            case 'TT': return d.getHours() < 12 ? 'AM' : 'PM';
            case 'Z': return d.toUTCString().match(/[A-Z]+$/);
            default: return $0.substr(1, $0.length - 2);
        }
    });
};

这是借鉴某人的，好东西

 

该说的都说了，还是靠自己领悟吧
