我想從我的日曆中禁用過去的日期，我去了一些文章。但沒有什麼會幫助很大。如何從我的日曆中禁用過去的日期？

這裏是我的代碼

import('form.FormElement'); 
    import('DateAndTime'); 

    class Calendar extends FormElement { 
var $holidays = array();

    return @$out; 
    } 
    else

}

}

如何從當前日期禁用過去的日期？我嘗試了類似的問題幾篇文章，但無法實現它，下面是我試圖提前

謝謝:)

您必須創建一個新的日期對象，並將其設置爲的minDate當你初始化datepickers

<label for="from">From</label> <input type="text" id="from" name="from"/> <label for="to">to</label> <input type="text" id="to" name="to"/> 

    var dateToday = new Date(); 
    var dates = $("#from, #to").datepicker({ 
defaultDate: "+1w", 
changeMonth: true, 
numberOfMonths: 3, 
minDate: dateToday, 
onSelect: function(selectedDate) { 
    var option = this.id == "from" ? "minDate" : "maxDate", 
     instance = $(this).data("datepicker"), 
     date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings); 
    dates.not(this).datepicker("option", option, date); 
} 
});
