Question

我每月下降,但纽特敦,如果按上月的原封面网页选定月贬值值,则希望解冻顿。

Answer 1

如果经常减少,只选择一个选项,则可以缩短换功能。

function checkDate() {
    var doc = document;

    var btn = doc.getElementById( <%=btnSave.ClientID %> );
    var slc = doc.getElementById( <%=ddlMonths.ClientID %> );

    btn.disabled = (slc.selectedIndex < (new Date()).getMonth());
}

Answer 2

You should use javascript for this. Use this function on onchange="checkdate()" of your drop down you can also set it from code behind file. write this in Page_Load function of your page...

 ddlMonths.Attributes.Add("onchange", "checkdate()");

ddl Months是你们的下降 Id

function checkdate()// to check Month
{
    var ddlMonths = document.getElementById( <%=ddlMonths.ClientID %> );
    var btnSave =document.getElementById( <%=btnSave.ClientID %> );
    var lCurrentMonth = (new Date()).getMonth();

     if(ddlMonths.options[ddlMonths.selectedIndex].value < lCurrentMonth) 
          btnSave.disabled= true;
     else
         btnSave.disabled= false;
}

如果你从11-12个月开始,你就可以将1个月的时间从零点开始,从0到11天开始,给你在名单上的摩托人以价值。
