所以最近我开始这个页面,其中一堆动态的东西汇集在一起,所以这里是......
1)用户选择(在表单中)他希望看到的数据库表HYDRO中的哪些列(假设这里的例子他选择了PM1,PM2,PM3)
2)然后用户选择实时或静态图表I.e.实时更新图表或过去24小时内的概述(此处为现场示例)
3)
图表被加载,PHP获取包含所有列的数组以及要加载它们的表的名称。
然后,对于每一列,PHP将行时间戳作为标签输出,并将所选列行值作为值输出到Chart.js中的脚本
之前曾经有过这样的工作,但遗憾的是,因为我进入了foreach php循环来遍历不同的图形,所以它们不再显示了......
我尝试使用$(document).ready(function(){});
,但这并不令人遗憾。

我知道这看起来一定很混乱,但简单的事情是根据php输入加载动态jQuery脚本,在页面加载之前放入jQuery会使jQuery无法工作,这里是网站页面的链接 http://hmorreels.hol.es/Morreels_App/index.php/charts
我希望有人花时间研究这个问题,我一直在努力尝试而且不会加载:/无论我尝试什么......
PS:我不是在试图懒惰,并且要求你们解决我的问题就像那样,我似乎无法理解整个动态加载jQuery脚本以及为什么他们有时不这样做工作,有时候他们会...一些额外信息:
PHP中使用的$full
数组以这种方式包含多个选定的列:
这是使用的包含所有值的atabase表结构的图片
答案 0 :(得分:1)
很抱歉浪费(或许)你们有些时间的男生/女孩,
我显然不应该按照我的方式命名我的画布, 这与其他一些jQuery变量相冲突,显然搞砸了整个事情,这已经修复了
(更新系统中的一些小错误,但主要问题是修复!! :))
