帮忙查错：实现求出时间差值

日期形式是固定的：YYYY－MM－

解决方案 »

  1.   

    后来修改一下实现功能的函数，但还是不行，不知那里出错，急啊！！！function SetDate()
    {
    var objEndDate=document.getElementById("txtEndDate");
    var mEndDate=objEndDate.innerText;

    var objStartDate=document.getElementById("txtStartDate");
    var mStartDate=objStartDate.innerText;
    var objDateTime=document.getElementById("DateTime");   var time1=new Date(mEndDate.replace("-","/").replace("-","/"));
    var time2=new Date(mStartDate.replace("-","/").replace("-","/")); if((time1.getTime()-time2.getTime())>0)
        objDateTime.innerText=time1.getTime()-time2.getTime();
    else
        objDateTime.innerText="0";}
