jQuery函数将日期与当前日期进行比较 [英] jQuery function to compare date with current date

问题描述

我通过在单独的文本框中输入日期，从下拉列表中选择年份并在文本框中输入年份来输入表格中的出生日期。现在我想检查输入的日期不能大于jquery中的当前日期。请帮忙怎么样？

i am entering date of birth in form by entering date in separate text box ,selecting year from drop down and entering year in text box. Now i want to check that entered date must not be greater that current date in jquery. Please help how?

var CurrentMonth = date.getDate() + '/' + date.getMonth() + '/' + date.getFullYear();
    var SelectedDate = $('[id$=spDate]').val() + '/' + $('[id$=drpMonth]').val() + '/' + $('[id$=txtYear]').val();
    if (CurrentDate > SelectedDate) {
        return false;
    } 

推荐答案

如果您的输入值是整数，你可以构建一个 日期 使用它们的实例：

Provided that your input values are integers, you can construct a Date instance using them:

var CurrentDate = new Date();
var SelectedDate = new Date(
    $('[id$=txtYear]').val(),
    $('[id$=drpMonth]').val(),
    $('[id$=spDate]').val()
);

//As quite rightly mentioned, January = 0, so if your inputs have the literal number for each month (1 for January) replace the line above with the following, to take a month off:
//var SelectedDate = new Date($('[id$=txtYear]').val(), $('[id$=drpMonth]').val()-1, $('[id$=spDate]').val());

if(CurrentDate > SelectedDate){
    //CurrentDate is more than SelectedDate
}
else{
    //SelectedDate is more than CurrentDate
}
