javascript - 在日历应用程序中切换月份的箭头

Question

我想使用 javascript 开发一个日历，但我不知道如何处理这种情况，我的意思是我想使用 2 个箭头（一个向左，一个向右）来切换月份和年份显示天数。当按下右箭头切换到下个月等时，我该怎么做？

不久前，我修改了jQuery datepicker以支持这种事情。我没有 git 或任何东西的来源，所以这里是：http: //jsfiddle.net/ZUrJY/2/

更改的相关部分在_generateHTML方法中。

var prev = (this._canAdjustMonth(inst, -1, drawYear, drawMonth) ?
'<a style="left: 22px;" class="ui-datepicker-prev ui-corner-all" onclick="DP_jQuery_' + dpuuid +
'.datepicker._adjustDate(\'#' + inst.id + '\', -' + stepMonths + ', \'M\');"' +
' title="' + prevText + '"><span class="ui-icon ui-icon-circle-triangle-' + (isRTL ? 'e' : 'w') + '">' + prevText + '</span></a>' :
(hideIfNoPrevNext ? '' : '<a style="left: 22px;" class="ui-datepicker-prev ui-corner-all ui-state-disabled" title="' + prevText + '"><span class="ui-icon ui-icon-circle-triangle-' + (isRTL ? 'e' : 'w') + '">' + prevText + '</span></a>'));

prev += (this._canAdjustMonth(inst, -12, drawYear, drawMonth) ?
'<a class="ui-datepicker-prev ui-corner-all" onclick="DP_jQuery_' + dpuuid +
'.datepicker._adjustDate(\'#' + inst.id + '\', -' + 12 + ', \'M\');"' +
' title="Prev Year"><span class="ui-icon ui-icon-circle-arrow-' + (isRTL ? 'e' : 'w') + '">Prev Year</span></a>' :
(hideIfNoPrevNext ? '' : '<a class="ui-datepicker-prev ui-corner-all ui-state-disabled" title="Prev Year"><span class="ui-icon ui-icon-circle-arrow-' + (isRTL ? 'e' : 'w') + '">' + prevText + '</span></a>'));

var nextText = this._get(inst, 'nextText');
nextText = (!navigationAsDateFormat ? nextText : this.formatDate(nextText,
this._daylightSavingAdjust(new Date(drawYear, drawMonth + stepMonths, 1)),
this._getFormatConfig(inst)));
var next = (this._canAdjustMonth(inst, +1, drawYear, drawMonth) ?
'<a style="right: 22px;" class="ui-datepicker-next ui-corner-all" onclick="DP_jQuery_' + dpuuid +
'.datepicker._adjustDate(\'#' + inst.id + '\', +' + stepMonths + ', \'M\');"' +
' title="' + nextText + '"><span class="ui-icon ui-icon-circle-triangle-' + (isRTL ? 'w' : 'e') + '">' + nextText + '</span></a>' :
(hideIfNoPrevNext ? '' : '<a style="right: 22px;" class="ui-datepicker-next ui-corner-all ui-state-disabled" title="' + nextText + '"><span class="ui-icon ui-icon-circle-triangle-' + (isRTL ? 'w' : 'e') + '">' + nextText + '</span></a>'));

next += (this._canAdjustMonth(inst, +1, drawYear, drawMonth) ?
'<a class="ui-datepicker-next ui-corner-all" onclick="DP_jQuery_' + dpuuid +
'.datepicker._adjustDate(\'#' + inst.id + '\', +' + 12 + ', \'M\');"' +
' title="Next Year"><span class="ui-icon ui-icon-circle-arrow-' + (isRTL ? 'w' : 'e') + '">Next Year</span></a>' :
(hideIfNoPrevNext ? '' : '<a class="ui-datepicker-next ui-corner-all ui-state-disabled" title="Next Year"><span class="ui-icon ui-icon-circle-arrow-' + (isRTL ? 'w' : 'e') + '">' + nextText + '</span></a>'));
