判斷選擇時間不能小於當前時間的方法有很多,在本文為大家詳細介紹下使用js是如何實現的,感興趣的朋友可以嘗試操作下
復制代碼代碼如下:
var controldate;
function checkDate(){
controldate= document.getElementById("sendDate").value;
if(controldate==""){
alert('日期不能為空');
return false;
}else{
var day = new Date(); var Year = 0;
var Month = 0;
var Day = 0;
var CurrentDate = "";
//初始化時間
Year = day.getFullYear();
Month = day.getMonth()+1;
Day = day.getDate();
//www.jbxue.com
CurrentDate += Year + "-";
if (Month >= 10 )
{
CurrentDate += Month + "-";
}
else
{
CurrentDate += "0" + Month + "-";
}
if (Day >= 10 )
{
CurrentDate += Day ;
}
else
{
CurrentDate += "0" + Day ;
} //alert(CurrentDate);//當前日期
var startDate = new Date(CurrentDate.replace("-",",")).getTime() ;
var endDate = new Date(controldate.replace("-",",")).getTime() ; if( startDate > endDate )
{
alert('選擇日期不能小於當前日期!');
document.getElementById("sendDate").focus();
return false;
}else{
return true;
}
}
}
function checkDate(){
controldate= document.getElementById("sendDate").value;
if(controldate==""){
alert('日期不能為空');
return false;
}else{
var day = new Date(); var Year = 0;
var Month = 0;
var Day = 0;
var CurrentDate = "";
//初始化時間
Year = day.getFullYear();
Month = day.getMonth()+1;
Day = day.getDate();
//www.jbxue.com
CurrentDate += Year + "-";
if (Month >= 10 )
{
CurrentDate += Month + "-";
}
else
{
CurrentDate += "0" + Month + "-";
}
if (Day >= 10 )
{
CurrentDate += Day ;
}
else
{
CurrentDate += "0" + Day ;
} //alert(CurrentDate);//當前日期
var startDate = new Date(CurrentDate.replace("-",",")).getTime() ;
var endDate = new Date(controldate.replace("-",",")).getTime() ; if( startDate > endDate )
{
alert('選擇日期不能小於當前日期!');
document.getElementById("sendDate").focus();
return false;
}else{
return true;
}
}
}
