我希望能够创建，到底从属性的元素创建HighCharts图的angularjs指令。我有一个指导工作，但任何动态设置属性返回undefined。最后，我希望所有的元素的属性被发送到一个$ http请求的PARAMS。

我已经使用$观察方法尝试和它似乎并没有工作，还我想的属性是什么，而不是predefined。

看到这个小提琴： http://jsfiddle.net/F52SF/ 并低于code指令：

  myApp.directive（示例，函数（）{    返回{        限制：'A'，        链接：功能（范围，元素，ATTRS）{            的console.log（'LOG1：'，attrs.exampleId）;            ATTRS。观察$（'exampleAttr'，函数（）{                的console.log（'LOG2：'，attrs.exampleId）;            }）;            VAR数据= {};            对（在ATTRS变种I）{                VAR T = Object.prototype.toString.call（ATTRS [I]）;                如果（T =='的翻译：'和;！＆amp; T公司='[对象功能]'！）数据[I] = ATTRS [I]            }            的console.log（数据）;        }    }}）; 

解决方案

在您的例子code有几个错误/改进：

其更好的阅读传递价值回调$观察功能：

  ATTRS。观察$（'exampleAttr'，函数（newValue）以{    / *使用为newValue这里，而不是attr​​s.exampleAttr * /}）;

I would like to be able to create a angularjs directive that in the end creates a HighCharts graph from the elements attributes. I have a directive working but any dynamically set attributes are returning undefined. In the end i want all the attributes on the element to be sent to a $http request as params.

I have tried using the $observe method and it does not seem to work, also i would like the attributes to be anything and not predefined.

See this fiddle: http://jsfiddle.net/F52SF/ and code below of directive:

myApp.directive('example', function () {
    return {
        restrict: 'A',
        link: function (scope, element, attrs) {
            console.log('Log1:', attrs.exampleId);
            attrs.$observe('exampleAttr', function () {
                console.log('Log2:', attrs.exampleId);
            });

            var data = {};
            for(var i in attrs){
                var t = Object.prototype.toString.call( attrs[i] );
                if(t !== '[object Object]' && t != '[object Function]') data[i] = attrs[i];
            } 
            console.log(data);
        }
    }
});

In your example code there are couple of mistakes/improvements:

Its better to read value passed to callback of $observe function:

attrs.$observe('exampleAttr', function(newValue) {
    /* use newValue here instead of attrs.exampleAttr */
});
