我正在使用两个下拉菜单(月,年)。我要根据年限制未来月份。假如我选择'2014',它应该显示截至1月的月份。我没有任何线索如何解决这个问题。请正确指导
<div class="width2 margin-bottom margin-top">
<div class="profile-text">
<span class="red">*</span> Certified On
</div>
<div class="profile-right">
<s:select list="#{'':'---Select Month---','Jan':'Jan','Feb':'Feb',
'Mar':'Mar','Apr':'Apr','May':'May','Jun':'Jun','July':'July',
'Aug':'Aug','Sep':'Sep','Oct':'Oct','Nov':'Nov','Dec':'Dec'}"
name="month" id="month" data-toggle="tooltip"
title="Please enter the month" cssStyle="height:32px; width:49%;"
placeholder="Month" cssClass="profile-input "/>
<s:select list="yearList" name="year" id="year" data-toggle="tooltip"
title="Please Enter Year" headerKey="" headerValue="--Select Year--"
cssStyle="height:32px; width:49%;" placeholder="Year"
cssClass="profile-input">
</s:select>
</div>
</div>

试试这种方式
$('#year').on('change',function() {
var currMon= (new Date).getMonth();
var currYear = (new Date).getFullYear();
if(currYear === $('#year :selected').text()){
$('#month option:eq('+currMon+')').prop('selected', true);
$('#month').prop('disabled',true);
}
else{
$('#month').prop('disabled',false);
}
});
注意:月份选择的值应为0
到11
,代表jan到dec
快乐编码:)

$('#year')。on('change',function(){
var option = [“Jan”,“Feb”,“Mar”,“Apr”,“May”,“June”,“July”,“Aug”,“Sep”,“Oct”,“Nov” , “DEC”];
var currMon =(new Date).getMonth();
var currYear =(new Date).getFullYear();
$( '#月')的html( '');
if(currYear == $('#year:selected')。text()&amp;&amp; currMon == 0){
for(i=0; i<=currMon; i++)
{
$('#month').append($("<option />").val(option[i]).text(option[i]));
}
}else
{
for(i=0; i<=11; i++)
{
$('#month').append($("<option />").val(option[i]).text(option[i]));
}
}
});
