HomeBackend DevelopmentPHP Tutorialjavascript - 新人求教:前后端交互的问题

刚入行前端,页面能写,但是一遇到跟后端协作就晕了,最近有个需求,微信上活动刮刮卡一类的,判断一个人有没有刮奖的次数,同事告诉我这是他做,他打个变量给我,让我判断这个变量?同事做php的。。。请问什么叫打个变量给我啊,我怎么接收呢?同事也没提到用ajax让我发送请求。

刚入行前端,页面能写,但是一遇到跟后端协作就晕了,最近有个需求,微信上活动刮刮卡一类的,判断一个人有没有刮奖的次数,同事告诉我这是他做,他打个变量给我,让我判断这个变量?同事做php的。。。请问什么叫打个变量给我啊,我怎么接收呢?同事也没提到用ajax让我发送请求。

打个变量就是类似于
<script>var hasUsed = <?echo $has_used?>;</script>

您拿到了这个变量hasUsed进行判断即可

在你的代码中为他的变量预留位置就可以了,比如:

<code><script>
var countTime = <?php echo $countTime?>;
</script></code>

其中的就是你那同事打过来的变量,在页面正式执行之后会变成

<code><script>
var countTime = 5;
</script></code>

在开发的时候你可以这样做

<code><script>
var countTime = 5;//<?php echo $countTime?>;
</script></code>

这样你可以先测试自己的代码逻辑了,如果一切ok,恢复成例1的样子就搞定啦,很简单吧。

我试一下怎么用,借你的试试

你问的问题太入门了,不会就虚心地向同事请教吧
