将多个输入值克隆到一个输入字段中 [英] Clone multiple input values into one input field

问题描述

我正在尝试将多个字段的输入数据复制到一个大字段中，以作为生日.

I'm trying to copy the input data of multiple fields into one big one, for date of birth.

日值+月值+年值=日值/月值/年值一起进入另一个字段.我在每个字段中都做了变量，然后尝试将它们添加到完整"输入字段中，但这是行不通的.我在做什么错了?

day value + month value + year value = day value/month value/year value into one other field all together. I made variables of each field and then try to add them in the 'full' input field, but this doesn't work. What am I doing wrong?

演示: http://jsfiddle.net/J2PHq/

$(function(){
    $('.copy').on('keyup blur', function(){
         $('.full').val(day + '/' + week + '/' + year);

        day = $(".day").val();
        week = $(".week").val();
        year = $(".year").val();
     }).blur();
});

推荐答案

您需要先声明变量，然后才能在.full字段中输入变量.

You need to declare the variables before you enter them in the .full field.

正在工作的小提琴:此处

$(function(){
    $('.copy').on('keyup blur', function(){        
        var day = $(".day").val();
        var week = $(".week").val();
        var year = $(".year").val(); 

        $('.full').val(day + '.' + week + '.' + year);

     }).blur();
});
