自动激活activex control

布满荆棘的人生 2022-09-18 06:50 1阅读 0赞

微软调整了浏览器ａｃｔｉｖｅｘ的策略，在被激活之前不能对他进行操作，没有激活时许多事件被屏蔽

被屏蔽事件如下

解决办法有下面几种（主要是由外部ｊｓ文件动态载入控件以避免激活）

１．用document.write动态载入（注意不能使用writeln，如果使用ｗｒｉｔｅｌｎ将会和直接载入一样要激活）

<html>
      <body leftmargin=0 topmargin=0 scroll=no>
        <script src="docwrite.js"></script>
      </body>
    </html>

// docwrite.js
    document.write('<object classid="clsid:6BF52A52-394A-11d3-B153-00C04F79FAA6">');
    document.write('<param name="URL" value="example.wmv">');
    document.write('<param name="autoStart" value="-1"></object>');

２．用ＯｕｔｅｒＨｔｍｌ

<html>
      <body> 
        <div id="embedControlLocation">
          <script src="embedControlOuterHTML.js"></script>
        </div>
      </body>
    </html>

// outerhtml.js
    embedControlLocation.outerHTML = '<embed src="examplecontrol">';

３．用createElement

<html>
      <body> 
        <div id="DivID">
          <script src="createElementExplicit.js"></script>
        </div>  
      </body>
    </html> 
     // createElementExplicit.js
    var myObject = document.createElement('object');
    DivID.appendChild(myObject);
    myObject.width = "200";
    myObject.height = "100";
    myObject.classid= "clsid:6BF52A52-394A-11d3-B153-00C04F79FAA6"; 
    myObject.URL = "example.wmv";
    myObject.uiMode = "none" ; 
       
     ４．ｉｎｎｅｒＨｔｍｌ 
     <html>
    <head>
    <script src="external_script.js" language="JScript"></script>
    </head>
    <body>
    <div id="EXAMPLE_DIV_ID">
    This text will be replaced by the control
    </div>
    <script language="JScript">
    CreateControl( "EXAMPLE_DIV_ID",
    "clsid:6BF52A52-394A-11d3-B153-00C04F79FAA6",
    "EXAMPLE_OBJECT_ID", "600", "400", "example.wmv",
    "-1")
    </script>
    </body>
    </html> 
     // external_script.js
    function CreateControl(DivID, CLSID, ObjectID,
                           WIDTH, HEIGHT, URL, AUTOSTART)
    {
      var d = document.getElementById(DivID);
      d.innerHTML = 
        '<object classid=' + CLSID + ' id=' + ObjectID + 
        ' width=' + WIDTH + ' height=' + HEIGHT +'>
        <param name="URL" value=' + URL + '>
        <param name="autoStart" value=' + AUTOSTART + '/>';
    }
