Javascript focus question

[dididaman]

How can I check if a field is 'allowed' to accept focus?

disabled , hidden, or invisible fields can't...Is there an easy way to check?

[jatar_k]

for disabled

if (document.formname.element.disabled == true)

you can change the values of hidden or invisible elements in the script but I don't quite understand why you would need to test for that.

The lazy route :)

try {
document.getElementById('hidden-field').focus()
} catch(e) {
alert("can't focus because of\n\n" + e)
}
