Object error

[thysonj]

Why do I get an "object doesn't sopport this property or method" error witht he code below?

function setfocus(field)
{
str = 'document.grid.' + field
str.focus();	
}

The field is dynamic but the form will stay the same.

because "str" is a string, not an element.

try this instead:

function setfocus(field)
{
el = document.grid.elements[ field ];
el.focus();    
}

try { succeed(); } catch(E) { tryAgain(); } finally { rtfm(); }

Unless the "field" parameter is an object, such as 'this'.

Then you'll have to do:

function setfocus(field) {
document.grid.elements[field].focus();
el.focus();
}

or:
function setfocus(field)
{
str = 'document.grid.' + field+'.focus()';
eval(str);
}


Known is handfull, Unknown is worldfull

Although a valid alternative, I would seriously avoid the use of eval, as it is unnecessary, and is a lot slower than other methods presented.

Hope this helps,
