Question

我输入的日期类型如下。在上面的示例中，我无法选择当前日期。请帮忙。检查添加的代码段

function CheckD()
{
    var current=new Date(document.getElementById('task_date').value);
    var today=new Date();
    if(current.getTime() <= today.getTime())
    {
        alert("You Can't Assign Task For Expired Date");
        document.getElementById('task_date').value="";
    }
    else
    {
        return true;
    }
}

<input type="date" id="task_date" name="task_date" class="form-control" onchange="return CheckD();">

Answer 1

可能是因为您使用的git clone每秒会改变一次，所以在这种情况下getTime是合适的

getDate

function CheckD() {
  var current = new Date(document.getElementById('task_date').value);
  var today = new Date();
  if (current.getDate() < today.getDate()) {
    alert("You Can't Assign Task For Expired Date");
    document.getElementById('task_date').value = "";
  } else {
    return true;
  }
}

Answer 2

使用getDate（）代替使用getTime（）

function CheckD()
{
    var current=new Date(document.getElementById('task_date').value);
    var today=new Date();
    if(current.getDate() < today.getDate())
    {
        alert("You Can't Assign Task For Expired Date");
        document.getElementById('task_date').value="";
    }
    else
    {
        return true;
    }
}

<input type="date" id="task_date" name="task_date" class="form-control" onchange="return CheckD();">

Answer 3

理想情况下，您应该使用Akhil＆brk指出的getDate()，

但是出于某些原因，如果必须使用getTime()，请将函数更改为：

function CheckD()
{
    var current=new Date(document.getElementById('task_date').value);
    var today=new Date();
  today.setHours(0,0,0,0);// <-- this will effectively change time component to 00:00:00 
    if(current.getTime() < today.getTime())
    {
        alert("You Can't Assign Task For Expired Date");
        document.getElementById('task_date').value="";
    }
    else
    {
        return true;
    }
}

<input type="date" id="task_date" name="task_date" class="form-control" onchange="return CheckD();">

Answer 4

只需更改

if(current.getTime() <= today.getTime())

对此

if(current.getDate() < today.getDate() )

不允许输入类型以选择过期日期
