deal_ajax.php

PHP code

<?phpecho "#######@".$_REQUEST['url'];?>

点击“保存”按钮可以异步提交到deal_ajax.php，但是马上就走form的action了！！！！用post也是

[解决办法]
<td><input name="save" type="button" value="保存" id="save" onclick="submit_form('later')"/></td>
<td><input name="fabu" type="button" value="发布" id="fabu" onclick=""/></td>
[解决办法]
type="submit"

改成
type="button"
[解决办法]
onclick="submit_form('later');return false"
[解决办法]

PHP code

echo "<meta http-equiv='Content-Type' content='text/html; charset=utf-8' />" .        "<script type='text/javascript' language='javascript'>".        "if(confirm('ok')){" .        "    window.location.href='{$href}';" .        "} else{            history.back();        }" .        "</script>";        exit;
