设置日期英特尔 XDK 引导程序3 输入类型日期

Question

我要做的是选择一个datepicker的日期，然后在week1中调用函数mydateset(wk)来设置日期加上week2输入中的 7 天。

我的代码：

<input class="wide-control form-control default" type="date" id="week1"       style="font-weight: bold;" onblur="mydateset('week1')">
<input class="wide-control form-control default" type="date" id="week2"   style="font-weight: bold;">
<script>
    function mydateset(wk) {
        if (wk == 'week1') {
            var tt = document.getElementById('week1').value;
            window.alert("tt is = "+ tt );              
        }
        var ndate = new Date(tt);
        window.alert("date is = "+ ndate);
        var newdate = new Date(ndate);
        window.alert("newdate is = "+ newdate);
        newdate.setDate(newdate.getDate() + 8);
        var dd = newdate.getDate();
        var mm = newdate.getMonth() + 1;
        var y = newdate.getFullYear();
        var someFormattedDate = dd +'/' +mm + '/' + y;
        window.alert("(New date is = "+someFormattedDate );
        //document.getElementById('week2').value = someFormattedDate;
        $('#week2').val(someFormattedDate);
    }
</script>

如果至少超过 10，我必须用 0 填充日和月变量。我必须格式化字符串"yyyy-mm-dd"，以便日期选择器接受日期。
