JS 替换和时间插件的结合使用方法

<script>var d = '2013-07-21';var nd = d.replace(new RegExp('-', 'g'), ','); //替换全部document.write(nd);document.write('<br>');var a = 'phper_yang';var aa = a.replace('_','.');//替换一次document.write(aa);</script>

// 日期
    $('.date').datepicker({
        changeYear: true,
        changeMonth: true,
        minDate:null,
        maxDate:null,
        onClose: function(selectedDate) {
            $('.gap-date').datepicker('option','minDate', '+1m');
        }
    });
    // 日期范围
    $('.gap-date').datepicker({
        changeYear: true,
        changeMonth: true,
        maxDate:null,
        onClose: function(selectedDate) {
            var y, m, d;
            var arr = selectedDate.split('-');
            y = arr[0];
            m = arr[1] - 7;
            d = arr[2];
            $('.date').datepicker('option','maxDate', new Date(y, m, d));
        }
    });
