A scheme that resolves the first hidden element in a form to get focus--effects of a form

Many of the elements in the form are represented by, for example, Form.element[x];
The type of an element: the type of an element is represented by Element.type
With some of the above understanding, let's solve the first scenario in which a non-hidden element gets focus:
First, define an object as the application of the method:
var f=new Object ();
And then:

Copy Code code as follows:

F.getthefirstfocus=function () {
if (Document.forms.length > 0) {
for (Var i=0 i < document.forms[0].elements.length; i++)//traversing elements
{var ofield = document.forms[0].elements[i];
if (Ofield.type!= "hidden") {Ofield.focus ();}
Return
}
}
}
};
