show/hide checkbox question

[karren]

hi there,

i am trying to get a checkbox to show an input box when it is clicked on but i can't get it to work. here is the code i have so far:


<script type="text/javascript">
function showhide2(thismenu)
{
if(document.forms[0].ChangeInPracticeOther.value=='Left practice')
{
document.getElementById(thismenu).style.display="block";
}
else
{
document.getElementById(thismenu).style.display="none";
}

}
</script>


Reduced hours<input type="checkbox" name="ChangeInPracticeOther" value="reducedhours" />
Certain services/disease states not seen<input type="checkbox" name="ChangeInPracticeOther" value="servicesdisease" />
Left practice<input type="checkbox" name="ChangeInPracticeOther" value="Left practice" onClick="javascript: showhide2('menu4')" />

<div id='menu4' style='display: none'>
<br />
<br />
<i>If you selected "Left Practice", what work are you currently doing
now?</i><br />
</div>

can anyone help me out?? any help will be appreciated!

thank you!!!!!

Checkboxes are funny creatures. If you're certain of the final order of them, you can replace the corresponding line of JavaScript with:

if(document.forms[0].ChangeInPracticeOther[b][1].checked[/b])

...or you can do this:

for(var j=0; j<document.forms[0].ChangeInPracticeOther.length; j++)
{
 if(document.forms[0].ChangeInPracticeOther[b][j][/b].value=='Left practice' && document.forms[0].ChangeInPracticeOther[j].checked)
 {
  ...
 }//end if
}//end for

Note the use of the index following ChangeInPracticeOther. Since there are more than one, each is an array member.

'hope that helps.

hi dave,

thanks so much for your reply, but both your suggestions didn't seem to work. the div with the textbox i wanna show when the user clicks on the "Left practice" checkbox still does not appear. i do not get any javascript errors but the div remains hidden. i'm not sure what i am doing wrong since there are no errors.
