JavaScript中两个日期之间的差异

Question

Hi friends this piece of code is not returning the correct time difference between two times instead returning NaN can any one spot the mistake in my code , thanks in advance .

$("[id^='endTime']").change(function(){
var index = $(this).attr('id').slice(7);
var startTime = $('#startTime'+index).val();
var endTime = $(this).val();
    var result = (new Date(startTime.val) - new Date(endTime.val));
alert(parseInt(result , 10));

$('#result'+index).val(parseInt(endTime , 10) - parseInt(startTime , 10)); ;

Answer 1

取出.val来自new Date(startTime.val)和new Date(endTime.val)
