Javascript 保险丝坏了
我对整个开发领域都是新手。你能帮我找出下面的错误吗。我将FusionCharts用于一个学校项目,发现很难填充图表。我已经根据提供的教程创建了这些文件,但是包含了MYSQL元素来检索数据。档案如下: HTMLJavascript 保险丝坏了,javascript,php,mysql,Javascript,Php,Mysql,我对整个开发领域都是新手。你能帮我找出下面的错误吗。我将FusionCharts用于一个学校项目,发现很难填充图表。我已经根据提供的教程创建了这些文件,但是包含了MYSQL元素来检索数据。档案如下: HTML <!DOCTYPE html> <html> <head> <title>Fusion Charts Column 2D Sample</title> </head> <body

希望有人能帮我找出错误。如果我做了傻事,我会道歉
干杯 您为呈现图表而创建的JSON结构不正确,例如,“类别”应该有一个对象数组作为值,但您正在向其传递一个值数组,数据集中的数据键也是如此。您需要修改代码,或者也可以使用my。是否收到错误消息?否。图表不会打印/显示它。请尝试在AJAX请求的成功回调(即for循环之后)中移动图表实例化(即salesAnlysisChart=new FusionCharts({…)。
