js调用ocx控件(读写IC卡

1、注册OCX

开始--->cmd--->regsvr32 *.ocx

2、jsp调用ocx

<OBJECT ID="mscs_ocx" height=0 width=0     
CLASSID="CLSID:64605B9A-BF10-4F16-9303-5A512469E4DF"     
CODEBASE="dcic32.cab#version=1,0,0,1">//如果没有发现该控件，会去当前目录dcic32.cab解压安装该控件      
</OBJECT>   

3、js 里调用
document.getElementById('mscs_ocx');   


4、读写IC卡演示代码

<script language=javascript>      
var a,b,c,d,snr,data,datastr;      
a = Test.InitDev();      
c = Test.GetFunMessage();      
if(a == 0)      
{         
    b = 0;      
    d = 1;      
    while(d){      
    switch(b){      
        case 0:      
            a = Test.ResetCard();      
            c = "ResetCard";      
            if(a == 0){      
                alert(c+"操作成功,");      
                b = 1;      
            }else{      
                b = 200;      
            }      
        break;      
        case 1:      
            a = Test.SetCompanyID("PF","LS","12345678","1234567890123456","流通","123456","071120");

            c = "ReadBill";      
            if(a == 0){      
                alert(c+"操作成功,数据为："+datastr);      
                b = 5;
