Setting the initial focus in an HTML page

The sample SetFocus JavaScript function provided in the "LANSA for Web - A Developers's View" guide does not include all the possible Form -graphical- elements types. Consequently, for those types not included (e.g. radio buttons, push buttons, etc.), the focus is not set. To set the focus for drop downs (combo boxes), push buttons and radio buttons, the SetFocus function could be enhanced as follows:

function SetFocus()
{
var NumElements=document.LANSA.elements.length;
for (i=0; i<NumElements;i++)
{
    if (document.LANSA.elements[i].type=="select" ||
        document.LANSA.elements[i].type=="radio" ||
        document.LANSA.elements[i].type=="button" ||
        document.LANSA.elements[i].type=="checkbox" ||
        document.LANSA.elements[i].type=="textarea" ||
        document.LANSA.elements[i].type=="text")

    {
        if (document.LANSA.elements[i].value!=" ")
             document.LANSA.elements[i].select();
             document.LANSA.elements[i].focus();
            break;
    }
}
}
