我在用如下方法在angular中用D3.js 画图。第一部分是实现画图功能的。涉及到directive.js写指令,controller.js中写作用域scope,在页面中写指令的p三个部分。我的问题是:在把contoller.js中的作用域scope的值放入json中访问时,无法画出相同的图形了。
首先贴上能实现画图功能,但是scope值写在本地的代码:
1、directive.js
2、controller.js
3、left.html
以上方法便能画出 angular+d3.js的图,如下~
可是,问题来了,想把controller.js 中的数据,变成$http.get("grade.json").success(function(data)这样请求的文件内的数据。
grade.json的数据如下:
会出现错误。。。
为什么呀。。
Since instructions are used, try to use independent scopes to maintain the independence of instructions. In your situation, you can change it to this
It’s done. . . You can print the corresponding value of your
salesDataToPlot
,看看是不是null
,报错提示应该就是那里的原因;还有指令与控制器之间的数据传递要么使用独立作用域,然后使用scope
parameter binding in the instruction; or use the inherited scope.The key in the json file must be in double quotes
This is asynchronous during the $http request, and the directive is already being compiled when the dom is loaded. At that time, salesData is of course undefined.
You should be like this
