radio buttons + checked

[PC_Freak]

Hi all,

I have in my page the following form:

<form action="this.php" method="get" name="newsform">
<input type="radio" name="number" value="latest" checked="true" /> 5 latest news entries<br />
<input type="radio" name="number" value="all" /> All news entries<br />
<input type="radio" name="number" value="custom" /> Custom number: 
<input type="text" name="custom" size="2" maxlength="2" class="white" onchange="newsformchange()" />
<p><input type="submit" value="Submit" /></p>
</form>

and the javascript:

function newsformchange () {
  if ( document.newsform.custom.length < 1 )
    document.newsform.number['latest'].checked=true;
  if ( document.newsform.custom.length > 0 )
    document.newsform.number['custom'].checked=true;
}

but this code won't work! anyone an idea what the problem is

found the solution. you can't use onchange on a radio object, have to use onclick instead. also changed the JS to

function newsformchange () {
  document.newsform.number[0].checked = 0;
  document.newsform.number[2].checked = 1;
}

ow man I'm a JS-noob

This works:

function newsformchange () {
  if ( document.newsform.custom.value.length <= 1 )
    document.newsform.number[0].checked=true;
  else
    document.newsform.number[2].checked=true;
}
