JS判断时间段的实现代码

<th>交易时间开始:</th>             

<td><input id="bccondatebegindate" name="bccondatebegindate" value="2016/06/12 00:00:00" class="easyui-datetimebox" editable="false" style="width: 150px;" /></td> 
            <th>交易时间结束:</th> 
            <td><input id="bccondateenddate" name="bccondateenddate" value="2016/06/12 23:59:59" class="easyui-datetimebox" editable="false" style="width: 150px;" /></td> 
var v = $('#bccondatebegindate').datetimebox('getvalue'); 
  if(v.length>0){ 
    var date = new date(); 
    var year = date.getfullyear(); 
    var month = date.getmonth() + 1; 
    var strdate = date.getdate(); 
    if (month >= 1 && month <= 9) { 
      month = "0" + month; 
    } 
    if (strdate >= 0 && strdate <= 9) { 
      strdate = "0" + strdate; 
    } 
    var nowdate = year+"/"+month+"/"+strdate; 
    var data1 = date.parse(v.substring(0,10).replace(/-/g,"/"));  
    var data2 = date.parse(nowdate); 
    var datadiff = data2-data1;  
    var time = 6*24*60*60*1000;  
    if(datadiff>time){ 
      $.messager.alert('提示', '开始时间不能超过当前时间前7天!'); 
      return; 
    } 
  }
