Lets say Id of ur textboxs is txt1, txt2 and txt3, then u can do it like

  function validate()
  {
      var txt1Value = document.getElementById("<%=txt1.ClientID%>").value;
      var txt2Value = document.getElementById("<%=txt2.ClientID%>").value;
      var txt3Value = document.getElementById("<%=txt3.ClientID%>").value;
      if(txt1Value != "" || txt2Value != "" || txt3Value != "")
      {
            return true;
      }
      return false;
  }

U can also use trim(), mentioned below

function trim(s)
{
    return rtrim(ltrim(s));
}

function ltrim(s)
{
    var l=0;
    while(l < s.length && s[l] == ' ')
    {   l++; }
    return s.substring(l, s.length);
}

function rtrim(s)
{
    var r=s.length -1;
    while(r > 0 && s[r] == ' ')
    {   r-=1;   }
    return s.substring(0, r+1);
}

Use this.

<script type="text/javascript">
var oneFilled = false;
for(var a = 0 ; a < 3 ; a ++)
{
    if($('input').eq(a).val() != "")
    oneFilled = true
}
return oneFilled;
</script>
