[Javascript] access form.element by name containing [ ]

[javascript@xxxxxxxxxx (Rodney Myers)]

<input type="text"   name="action[upd]" value="abcd">
<input type="button" name="b1" value="ALERT TEST"
onclick="alert(this.form['action[upd]'].value)">

<input type="checkbox" name="action[new]" value="wxyz">
<input type="button" name="b1" value="CLICK TEST"
onclick="this.form['action[new]'].click()">

This worked in Win98 NN4.7 and MSIE 5.5
(in my test file crazy.htm<g>)
