<p>确认密码: <input type="password" name="pw" id="pw2" onkeyup="validate()"/><span id="tishi"></span></p>
<p><input type="submit" value="注册" id="submit"/>
<input type="reset" value="重置"/></p>
</form>
<script>
function validate() {
var pw1 = document.getElementById("pw1").value;
var pw2 = document.getElementById("pw2").value;
if(pw1 == pw2) {
document.getElementById("tishi").innerHTML="<font color='green'>两次密码相同</font>";
document.getElementById("submit").disabled = false;
}
else {
document.getElementById("tishi").innerHTML="<font color='red'>两次密码不相同</font>";
document.getElementById("submit").disabled = true;
