1:創建ActiveX對象
在web中使用ActiveX組件有兩種方法,一是如下
<HTML>
<HEAD>
<TITLE>rep_print_medcan.CAB</TITLE>
</HEAD>
<BODY>
<OBJECT ID="Rep_Print_MedCan21"
CLASSID="CLSID:C0558D51-6AFD-11D5-BF5C-005070024001"
CODEBASE="rep_print_medcan.CAB#version=1,0,0,25">
</OBJECT>
</BODY>
</HTML>
OBJECT標簽中,通過ID指點了對象的ID號,javascript可以使用該ID號來引用該對象,而classid用於標識這個組件,每個ActiveX組件都有唯一一個用於表示他的ID號。而codebase指定的程序下載到本地(在系統目錄的“Downloaded Program Files”子目錄下),然后調用組件程序的自注冊入口函數注冊到當前系統中,以后的創建都在本地進行,不再涉及codebase屬性
使用以上的方法來創建ActiveX對象,有些參數設置需要手抖的填寫,麻煩,
2、另外可以使用javascript的ActiveXObject對象來創建,一般過程是var act=new ActiveXObject(proid),proid為該ActiveX的標識號,是Classid的另一種表示方法
其中proid指在ocxctrl.cpp文件下的:
// 初始化類工廠和 guid
IMPLEMENT_OLECREATE_EX(CtestOCX2Ctrl, "TESTOCX2.testOCX2Ctrl.1",
0xe0d5a597, 0x336b, 0x4829, 0x84, 0xe0, 0x77, 0x43, 0x91, 0xc8, 0xe8, 0xdb)
紅色表示部分。
3、
var _tempPlayer = null;
_tempPlayer = window.document.createElement("object");
_tempPlayer.classid = "clsid:358DE739-F39F-4832-9458-80FDE806F845";
_tempPlayer.id = "realtime_player"+i; // 唯一標識
_tempPlayer.using = false; // 是否正在使用
_tempPlayer.style.width = "100%";
_tempPlayer.style.height = "100%";
或者:
/*var _tempPlayer = window.document.createElement("object");
_tempPlayer.setAttribute("id","realtime_player"+i);
_tempPlayer.setAttribute("classid","clsid:358DE739-F39F-4832-9458-80FDE806F845");
_tempPlayer.setAttribute("width","100%");
_tempPlayer.setAttribute("height","100%");
_tempPlayer.using = false; //>是否正在使用
4、檢測ocx是否可用的方法
在js下是 var o = new ActiveXObject(ProgID);
IE下若ocx存在是object,否則是null
即:
var o = new ActiveXObject(ProgID);
if(o)
{
//存在
}
else
{
//不存在
}
<HTML> <HEAD> <TITLE>New Page</TITLE> <script language="javascript" type="text/javascript"> //var a1 = new ActiveXObject("TESTOCX1.testOCX1Ctrl.1"); var ocx; function createOcx() { ocx = document.createElement("object"); ocx.setAttribute("id", "ocx1"); ocx.setAttribute("height", 100); ocx.setAttribute("width", 51); ocx.setAttribute("classid", "clsid:DA44C63F-4844-483F-9DA0-7129E1A7F05B"); } function DestoryOcx() { delete ocx; } function AddToDiv() { var div = document.getElementById("divOcxContainer"); div.appendChild(ocx); ocx.Method2(); } function RemoveFromDiv() { var div = document.getElementById("divOcxContainer"); var ocx1 = document.getElementById("ocx1"); div.removeChild(ocx1); } window.onload = function() { } window.onunload = function() { } </script> </HEAD> <BODY> <div id="divOcxContainer"> </div> <input type="button" id="btn1" name="btn1" value="創建ocx" title="創建ocx" onclick="createOcx()"></input> <input type="button" id="btn2" name="btn2" value="銷毀ocx" title="銷毀ocx" onclick="DestoryOcx()"></input> <input type="button" id="Button1" name="btn2" value="添加到div" title="添加到div" onclick="AddToDiv()"></input> <input type="button" id="Button2" name="btn2" value="從div移除" title="從div移除" onclick="RemoveFromDiv()"></input> <OBJECT ID="testOCX1" WIDTH=100 HEIGHT=51 CLASSID="CLSID:DA44C63F-4844-483F-9DA0-7129E1A7F05B"> <PARAM NAME="_Version" VALUE="65536"> <PARAM NAME="_ExtentX" VALUE="2646"> <PARAM NAME="_ExtentY" VALUE="1323"> <PARAM NAME="_StockProps" VALUE="0"> </OBJECT> <OBJECT ID="testOCX2" WIDTH=100 HEIGHT=51 CLASSID="CLSID:DA44C63F-4844-483F-9DA0-7129E1A7F05B"> <PARAM NAME="_Version" VALUE="65536"> <PARAM NAME="_ExtentX" VALUE="2646"> <PARAM NAME="_ExtentY" VALUE="1323"> <PARAM NAME="_StockProps" VALUE="0"> </OBJECT> </BODY> </HTML>
