证书签名控件:<PowerSignDAHSING.IESignDAHSING.1
<object id="iesign" codebase="ocx/PowerSignDAHSING.dll#version=1.0.0.5" classid="clsid:C0BC5EB7-9776-4669-8088-111BB01C7B37" name="iesign"</object
<div证书签名控件:<span id="acto1"</span</div<scripttry{//证书签名控件:
//id="iesign" codebase="ocx/PowerSignDAHSING.dll#version=1.0.0.5" classid="clsid:C0BC5EB7-9776-4669-8088-111BB01C7B37"
var axo1 = new ActiveXObject("PowerSignDAHSING.IESignDAHSING.1");
$("acto1").innerHTML = "已安装成功";}catch(e){$("acto1").innerHTML = "未安装";}</script
JavaScript检查ActiveX控件是否已经安装过
1.采用object元素的object属性是否为空可以判断此控件是否存在,
