bootstrap 和datapicker 样式不兼容修复

修改 datepicker.js内的

layout 方法

function(el) {
        var options = $(el).data('datepicker');
        var cal = $('#' + options.id);
        if (options.extraHeight === false) {
          var divs = $(el).find('div');
          options.extraHeight = divs.get(0).offsetHeight + divs.get(1).offsetHeight;  // heights from top/bottom borders
          options.extraWidth = divs.get(2).offsetWidth + divs.get(3).offsetWidth;     // widths from left/right borders
        }
        var tbl = cal.find('table:first').get(0);
        var width = tbl.offsetWidth;
        var height = tbl.offsetHeight;
        cal.css({
          width: width + options.extraWidth + 'px',
          height: height + options.extraHeight + 'px'
        }).find('div.datepickerContainer').css({
//            cdp 修改位置+30
          width: width + 30+'px',
          height: height + 'px'
        });
