automatically move cursor

hi guys

I have a field called Judgment number which is a combination of three fields like this

<html:text  style="fieldheight"  property="J_TYPE_CODE" size="4" maxlength="2" />
<html:text  style="fieldheight"  property="J_SEQUENCE_NUMBER" size="15" maxlength="6" />
<html:text  style="fieldheight"  property="J_NUMBER_YEAR" size="4" maxlength="2"/>

When user enters something in the first text box J_TYPE_CODE, i want the cusror to be automatically moved to the next text box
J_SEQUENCE_NUMBER  and then after entering something in the second text box i want the cursor to automatically move
to J_NUMBER_YEAR

i have seen this feature in many websites , any idea how i can do that

thanks

... assumes the generated HTML has name properties that match the properties above.

sorry, left out the elements array:

<html:text  style="fieldheight"  property="J_TYPE_CODE" size="4" maxlength="2"
onkeyup="if(this.value.length==this.value.maxLength)this.form.elements['J_SEQUENCE_NUMBER'].focus();" />


<html:text  style="fieldheight"  property="J_SEQUENCE_NUMBER" size="15" maxlength="6"
onkeyup="if(this.value.length==this.value.maxLength)this.form.elements['J_NUMBER_YEAR'].focus();" />

DOH!  Still had a typo -- really sorry.  The maxLength property belongs to the field, not the value of the field:


<html:text  style="fieldheight"  property="J_TYPE_CODE" size="4" maxlength="2"
  onkeyup="if(this.value.length==this.maxLength)this.form.elements['J_SEQUENCE_NUMBER'].focus();" />


<html:text  style="fieldheight"  property="J_SEQUENCE_NUMBER" size="15" maxlength="6"
  onkeyup="if(this.value.length==this.maxLength)this.form.elements['J_NUMBER_YEAR'].focus();" />
