本文介绍 Ext.Date 模块中的 parse 和 isValid 方法使用细节。解析如何通过指定格式字符串来解析日期，并验证输入日期是否有效，防止 JavaScript Date 的溢出现象。

curDay = Ext.Date.parse(Ext.Date.format(new Date(), 'Y-m-d'), 'Y-m-d');

if(Ext.Date.parse(orderDate, 'Y-m-d') < curDay) {

Ext.Msg.alert(NLC.Message.app.ajax_Msg_tTip, '预约日期必须晚于当前日期');

return;

    /**
     * Parses the passed string using the specified date format.
     * Note that this function expects normal calendar dates, meaning that months are 1-based (i.e. 1 = January).
     * The {@link #defaults} hash will be used for any date value (i.e. year, month, day, hour, minute, second or millisecond)
     * which cannot be found in the passed string. If a corresponding default date value has not been specified in the {@link #defaults} hash,
     * the current date's year, month, day or DST-adjusted zero-hour time value will be used instead.
     * Keep in mind that the input date string must precisely match the specified format string
     * in order for the parse operation to be successful (failed parse operations return a `null` value).
     *
     * Example:
     *
     *     // dt = Fri May 25 2007 (current date)
     *     var dt = new Date();
     *
     *     // dt = Thu May 25 2006 (today's month/day in 2006)
     *     dt = Ext.Date.parse("2006", "Y");
     *
     *     // dt = Sun Jan 15 2006 (all date parts specified)
     *     dt = Ext.Date.parse("2006-01-15", "Y-m-d");
     *
     *     // dt = Sun Jan 15 2006 15:20:01
     *     dt = Ext.Date.parse("2006-01-15 3:20:01 PM", "Y-m-d g:i:s A");
     *
     *     // attempt to parse Sun Feb 29 2006 03:20:01 in strict mode
     *     dt = Ext.Date.parse("2006-02-29 03:20:01", "Y-m-d H:i:s", true); // null
     *
     * @param {String/Number} input The raw date string.
     * @param {String} format The expected date string format.
     * @param {Boolean} [strict=false] (optional) `true` to validate date strings while parsing (i.e. prevents JavaScript Date "rollover").
     * Invalid date strings will return `null` when parsed.
