Focus No Input Text

hsimberg · Abril 15, 2006

ae gente

tenho um chat

e gostaria que assim que mandasse a mensagem e postasse, fizesse um 'focus' no lugarque manda mensagem ... pro usuario não ter que pegar o mouse e clicar la pra poder escrever de novo...entenderam? alguém sabe?

o codigo ta mais ou menos assim

<?php
session_start();
require "../login_db.php";
$handle = $_SESSION['login'];
if(isset($handle)){
    //
    // The world's least efficient wall implementation
    //
    require("Sajax.php");
    
    function add_line($msg) {
        $f = fopen("wall.html", "a");
        $dt = date("d/m - G:i:s");
        $msg = strip_tags($msg);
        $msg = wordwrap( $msg, 75, "<br>", 1);
        #$msg = strip_tags(stripslashes($msg));
        #
        $login = $_SESSION['login'];
        $c = mysql_query("SELECT * FROM members WHERE login = '$login'");
        $user_d = mysql_fetch_array($c);
        $name_completo = $user_d["first_name"]." ".$user_d["last_name"];
        $img_user = $user_d["dp"];
        $flag = $user_d["location"];
        #                
        fwrite($f, "<table width=100% border=1 align=center cellpadding=0 cellspacing=0 bordercolor=#CCCCCC style=border-collapse: collapse;>
  <tr>
    <td><table width=100% >
      <tr>
