Depends on how it may be being set to invisible.

If you hide it by doing "TextBox.Visible = False" in your code-behind, then the control will not be found by your clientside javascript so you can check using something like:
if (document.all.TextBox)
{
    // Textbox is present
}

Or, if you hide it using styles (e.g. style="display:none"), then you can check by:
if (document.all.TextBox.style.display=='none')
{
    // Textbox is invisible
}

Addendum to adathelad's answer. In addition to display you can also use the visibility style...

Or, if you hide it using styles (e.g. style="visibility:hidden"), then you can check by:
if (document.all.TextBox.style.visibility=='hidden')
{
    // Textbox is invisible
}
