我的表格是我与联合材料和共同财产计划一起验证的。 在我试图检查密码是否吻合时,所有东西都相距甚远。

形式如下:

<div>
                    <label for="passlength">Password, valid: 0-9</label>
                    <input type="text" name="passlength" value="<?=@$_REQUEST[ passlength ]?>" id="passlength" />
                    <span id="validatePasslength"><?php if ($error) { echo $error[ msg ]; } ?></span>
                </div>
                <div>
                    <label for="passlength">Password2, valid: 0-9</label>
                    <input type="text" name="passlength2" value="<?=@$_REQUEST[ passlength2 ]?>" id="passlength2" />
                    <span id="validatePasslength2"><?php if ($error) { echo $error[ msg ]; } ?></span>
                </div>

这就是 Java:

    var r = $( #passlength ).val()
;
        var validatePasslength2 = $( #validatePasslength2 );
        $( #passlength2 ).keyup(function () {

            var t = this;
            if (this.value != this.lastValue) {
                if (this.timer) clearTimeout(this.timer);
                validatePasslength2.removeClass( error ).html( <img src="../../images/layout/busy.gif" height="16" width="16" /> checking availability... );

                this.timer = setTimeout(function () {
                    $.ajax({
                        url:  ajax-validation.php ,
                        data:  action=check_passlength2&passlength=  + r +  &passlength2=  + t.value,
                        dataType:  json ,
                        type:  post ,
                        success: function (j) {
                            validatePasslength2.html(j.msg);
                        }
                    });
                }, 200);
                this.lastValue = this.value;
            }
        });

这里是:

//Check for passlength
        if (@$_REQUEST[ action ] ==  check_passlength  && isset($_SERVER[ HTTP_X_REQUESTED_WITH ])) {
        // means it was requested via Ajax
        echo json_encode(check_passlength($_REQUEST[ passlength ]));
        exit; // only print out the json version of the response
    }

    function check_passlength($password) {
//        global $taken_usernames, $usersql;
        $resp = array();
//        $password = trim($password);
      if (!preg_match( /^[0-9]{1,30}$/ , $password)) {
        $resp = array("ok" => false, "msg" => "0-9 Only");
    } else if (preg_match( /^[0-9]{1,2}$/ , $password)) {
                        $resp = array("ok" => false, "msg" => "Password too short");
        } else if (preg_match( /^[0-9]{6,30}$/ , $password)) {
                                $resp = array("ok" => false, "msg" => "Password too long");
    } else {
        $resp = array("ok" => true, "msg" => "Password ok");
    } 

        return $resp;
    }


//Check for passlength2
        if (@$_REQUEST[ action ] ==  check_passlength2  && isset($_SERVER[ HTTP_X_REQUESTED_WITH ])) {
        // means it was requested via Ajax
        echo json_encode(check_passlength2($_REQUEST[ passlength ],$_REQUEST[ passlength2 ]));
        exit; // only print out the json version of the response
    }

    function check_passlength2($password,$password2) {
//        global $taken_usernames, $usersql;
        $resp = array();
//        $password = trim($password);
      if (!preg_match( /^[0-9]{1,30}$/ , $password2)) {
                $resp = array("ok" => false, "msg" => "0-9 Only");
        } else if (preg_match( /^[0-9]{1,2}$/ , $password2)) {
                                $resp = array("ok" => false, "msg" => "Password too short");
        } else if (preg_match( /^[0-9]{6,30}$/ , $password2)) {
                                $resp = array("ok" => false, "msg" => "Password too long");
        } else if ($password !== $password2) {
                                $resp = array("ok" => false, "msg" => "Passwords do not match");
        } else {
                $resp = array("ok" => true, "msg" => "Password ok");
        }

        return $resp;
    }

I, pretty, is a issue with the j>, if I set : > >, 1234; It. ?
