The method by which JavaScript calculates the date between two date periods

This example shows how JavaScript calculates the date in two date time periods. Share with you for your reference. The specific implementation method is as follows:

/*************************

 *  Calculate all the dates in the two date periods  

 *  

 * @param value1 

 *             Start date  YYYY-MM-DD 

 * @param value2 

 *             End date  

 * return  Date of the array  

 */  

function dataScope(value1, value2) {  

    var getDate = function(str) {  

        var tempDate = new Date();  

        var list = str.split("-");  

        tempDate.setFullYear(list[0]);  

        tempDate.setMonth(list[1] - 1);  

        tempDate.setDate(list[2]);  

        return tempDate;  

    }  

    var date1 = getDate(value1);  

    var date2 = getDate(value2);  

    if (date1 > date2) {  

        var tempDate = date1;  

        date1 = date2;  

        date2 = tempDate;  

    }  

    date1.setDate(date1.getDate() + 1);  

    var dateArr = [];  

    var i = 0;  

    while (!(date1.getFullYear() == date2.getFullYear()  

            && date1.getMonth() == date2.getMonth() && date1.getDate() == date2  

            .getDate())) {  

         var dayStr =date1.getDate().toString();  

            if(dayStr.length ==1){  

                dayStr="0"+dayStr;  

            }  

        dateArr[i] = date1.getFullYear() + "-" + (date1.getMonth() + 1) + "-"  

                + dayStr;  

        i++;  

        /* 

         * document.write("<div style='display:block'>" + date1.getFullYear() + 

         * "-" + (date1.getMonth() + 1) + "-" + date1.getDate() + "</div>"); 

         */  

        // document.write(dateArr[i] + "<br>");  

        date1.setDate(date1.getDate() + 1);  

    }  

    return dateArr;  

}
