页面之间怎么传变量
<code><br><br><script> var test = [ "<a href='#' >1", "<a href='' >2", "<a href='' >3", "<a href='#' >4", "<a href='' >5", "<a href='' >6" ]; var a = test[Math.floor(Math.random() * test.length)]; document.write(a); </script> <?php $mes= "<script>document.write(a)"; ?> </code>
我把$mes 传到另一个php页面是<script>document.write(a)</script>
,无法调用,苦求解决方法。

如果是多页面应用。
那么你可以在querystring
中传,在后端重新输出变量到前端.http://url/a?key=value
如果是单页面应用,建议使用History APIpushState
popState
和 replaceState
有两种传递方式
第一种,显式的
通过url query string传递,如http://dict.youdao.com/search?q=中国
,其中的q
即为传递的参数
第二种, 隐式的
通过PHP中的SESSION传递,将要传递的内容预先保存在PHP SESSION中,跳转页面后让随后的页面去取SESSION中的值即可
php中:
$_GET 通过 URL 参数传递给当前脚本的变量的数组。
$_POST 通过 HTTP POST 方法传递给当前脚本的变量的数组。
所以,你可以把你要传给下一个页面的变量通过url的方式或者通过表单post的方式传递到下一个页面去。
批评一下:
你认为$mes会得到这段js执行的结果,这说明你基本功太薄弱了点,还是有必要补补基础知识的。
