php一个页面内 能不能监视 session变化啊该如何解决
php一个页面内 能不能监视 session变化啊
就是我用一个while 如果session等于指定的值的话 就返回结果 可是不行啊 很郁闷
是不是php在创建页面时session就赋值了 session再变化必须得刷新页面啊
------解决方案--------------------
是的，当session值改变后，你必须刷新页面才能看到新的值
但你可以这样做 用AJAX 就可以时时得到某个值了 如
- JScript code
//定时间执行$(document).ready(function(){ function autoAlt(){ //alert("bb"); $.post("ajax.php?act=memo", {act:"memo"}, function(redata){ if(redata!=""){ alert(redata); }, "text") } setInterval(autoAlt,1000);})<div class="clear">
</div>
