随笔，平日工作小记

编译器将发出错误信息：
      SpecialSetupChain is inaccessible due to its protection level.
因为:SetupUCChain的访问级别为 private ,改为 public,即可
  public SetupUCChain(){...}

public class SetupUCChain
{
   private SetupUCChain()
   {
            
   }
   protected virtual void Init()
   {
     
   }
}
public class SpecialSetupChain : SetupUCChain
{
   protected override void Init()
   {
     
   }
}

有这样一个数组：var strings = "6:0.03;7:0.04;8:0.05;"
只要取：如果只取0.03的话
function getTwoPoint()
{
   var regRule = new RegExp("(^|;)" + parseInt(6) + ":([0-9\\.]+)(;|$)");
   var payFeeRate = payFeeRateList.match(regRule)[2];
   payFeeRate = 0.03;
}

RMB 1900,如果想显示成1,900的话
function formatCur(){
    var m_num = this.toString();
    if (/[^0-9\.\-]/.test(m_num)) 
    {
       return m_num;
    }
    m_num = m_num.replace(/^(\d*)$/,"$1.");
    m_num = (m_num + "00").replace(/(\d*\.\d\d)\d*/,"$1");
    m_num = m_num.replace(".",",");
    var re = /(\d)(\d{3},)/;
    while (re.test(m_num))
    {
       m_num = m_num.replace(re,"$1,$2");
        }
    m_num = m_num.replace(/,(\d\d)$/,".$1");
    return m_num.replace(/^\./,"0.");
}

var number=1900;
number.formatCur();
result = 1,900.00
result = result.substring(0,result.length-3);
