How do I make a form field take focus ?

[Aaron Gray]

I want to make a form field take focus ideally coded in the form :-

<form method="post" action="index.php?action=newname">
<input type="text" name="name" size="40" value="" />
<input type="submit" name="submit" value="Create" />
</form>

Many thanks in advance,

Aaron

It is easy to prove me wrong though. Post a script that will determine
if an arbitrary form element can be focused or not.

<input type="text" onfocus="this.blur()" name="inputYouCantFocus">

There is too many way allowing us to hide and/or prevent the focus on an
element, let me add a few to the list.

1) the obvious <input type="hidden">

2) <input disabled="disabled">

3) <input style="opacity:0">

4) <input style="position:absolute;clip:rect(0,0,0,0)">

5)
<div style="overflow:hidden;width:0;height:0">
<input>
</div>

6)
<div style="position:absolute;z-index:1;width:300px;height:100px">
<input style="width:100px">
</div>
<div style="position:absolute;z-index:2;width:300px;height:100px;
background-color:red"></div>

7) with this one, the focus can occur only with a mouse. You got a
keyboard only, you are screwed and can't focus it at all. How a script
would be able to determine if the second input is focusable ?
<input>
<input tabindex="-1">

and many many more tricky ways to hide anything we want.

Happy scripting!

:D

Look through the thread I posted a URL to. It has a lot of examples of
inputs that can't have focus.

1) the obvious <input type="hidden">

2) <input disabled="disabled">

3) <input style="opacity:0">

4) <input style="position:absolute;clip:rect(0,0,0,0)">

5)
<div style="overflow:hidden;width:0;height:0">

6)
<div style="position:absolute;z-index:1;width:300px;height:100px">
<input style="width:100px">
</div>
<div style="position:absolute;z-index:2;width:300px;height:100px;
background-color:red"></div>

<input>
<input tabindex="-1">

and many many more tricky ways to hide anything we want.

style="visibility: none"
style="display: none"

But, just one is all it takes to show that you can't determine it with
script to prove that it is impossible.

I am curious to see his attempt at it. His last one failed miserably.
