这是代码：
<?php
$_SESSION['currentlocation'] = "combat.php";
if($_SESSION['ambush'] && $_SESSION['flee']) {
for($i = 0; $i < sizeOf($_SESSION['enemies']); $i++) {
$scaling = 20 - $_SESSION['enemies'][$i] -> luck;
if($_SESSION['enemies'][$i]-> rank >= 20 && $_SESSION['enemies'][$i]-> rank <
40) {
$prob = rand(1, 100);
if($prob <= 100) {
// if($prob <= 75 - $scaling * 3.8) {
if($_SESSION['comboAttack'] < 2) {
$_SESSION['comboAttack'] = 2;
}
$_SESSION['enemies'][$i]->comboAttack = 2;
$_SESSION['enemies'][$i]->attackMessage="Enemy #".strval($i)."pulls off
a 2-hit combo. \n";
}
}
else if($_SESSION['enemies'][$i]-> rank >= 40 && $_SESSION['enemies'][i]-> rank
< 60) {
$prob = rand(1, 100);
if($prob <= 50 - $scaling * 3.8) {
if($_SESSION['comboAttack'] < 3) {
$_SESSION['comboAttack'] = 3;
}
$_SESSION['enemies'][$i]->comboAttack = 3;
$_SESSION['enemies'][$i]->attackMessage="Enemy #".strval($i)."pulls off
a 3-hit combo. \n";
}
else if($prob <= 75 - $scaling * 3.8) {
if($_SESSION['comboAttack'] < 2) {
$_SESSION['comboAttack'] = 2;
}
$_SESSION['enemies'][$i]->comboAttack = 2;
}
}
if($_SESSION['enemies'][$i] != null) {
// $_SESSION['enemies'][$i]->attack($i);
// echo $_SESSION['enemies'][$i]->attackMessage;
}
?>
<script type="text/javascript">
$(document).ready(function() {
$('#combatinfo').append('<?php if($_SESSION['enemies'][$i] != null) echo
$_SESSION['enemies'][$i]->attackMessage; ?>');
});
</script>
<?php
}
?>
<button type="button">Defend</button> <button type="button">Flee</button>
<form action="index.php" method="post">
<input type="submit" name="submit" value="Submit" />
</form>
<?php
}
正如标题所述，我正在尝试将对象（光头）的文本字段中的文本附加到文本区域。上面的代码不起作用。但是，当我用这个替换一些代码时：
<script type="text/javascript">
$(document).ready(function() {
$('#combatinfo').append('<?php if($_SESSION['enemies'][$i] != null) echo
"HELLO WORLD!" ?>');
});
</script>
这行得通。
对象中的文本不为空，怎么不显示呢？感谢您的时间。
