Javascript judges the office version example

When we open the registry, we can see the version of office. The corresponding relationship between the office version and the key value of the registry is as follows:

11.0         office2003 ; 
12.0         office2007 ; 
14.0         office2010 ; 

var version="";
function readOfficeVersion()
{
    var word=null;
    try
    {
        word=new ActiveXObject("Word.application");
    }catch(e)
    {
        alert("1 Please check whether your machine has been installed Microsoft Office 2003/2007;/n2 You check that your browser Settings are enabled ActiveX The control. ");
    }
    if(word.Version==="11.0")
    {
        version="office2003";
    }
    else if(word.Version==="12.0")
    {
        version="office2007";
    }
    else if(word.Version==="14.0")
    {

        version="office2010";
    }    //Close the Word process in time
    word.Application.Quit();
    return version;
}
