javascript - php 跟 js 交互以及 js 选取
弱弱的问一下,大伙平常都是肿么传递数据的呢?
比如:需要查询数据库读取数据源,整理后需要用 js 渲染做个图表
我的想法是:
索引页是个 php,用户点击有兴趣的条目然后更新索引页。可是用什么方式更新页面比较合理呢?更新需要产生对应的图表,意味着需要查询数据库。用户点击条目是用 js 响应还是通过 GET 参数刷新当前页面呢?
另外就是 js 的选择,我是战五渣,只会一些简单的 jQuery,纯 js 写页面控制什么基本就是白痴。使用其他渲染库有一些是不依赖 jQuery 的,我也想让页面轻量一些,此时应该考虑学习纯 js 还是继续加载 jQuery 呢?

- 用户点击需要更新数据,建议使用
AJAX
后台查询。图标页面对体验的要求很高。同样,第一页的数据应该也是AJAX
获取的,这样可以让用户看到绘图
的动画过程,非常炫。 - 为什么不用
jQuery
,jQuery 改良了很多 js 的特性,让 js 变的跟 PHP 一样容易上手,非常强大。一个压缩过的 jQuery 库只有几十K
,用户随随便便一张图片就200K
,没必要省这一点点体积。
这个你可以看下restapi,查询是get请求。AJAX请求后得到数据,直接在页面渲染出来。
用 JSON 构建 API 的标准指南 还没有翻译完,希望对你有帮助。
php做好json数据,js接收,ajax,页面跳转都可以,图表的话可以用一些图表库,svg的raphael, d3. jquery用就用,很多好的特性,比如ajax,页面展现,不用是给自己找麻烦
