angular的自定义指令如何使用

angular.module(&#39;dir&#39;,[  ]).directive( &#39;mydir&#39; ,function(  ){   return {template:&#39;<div>hello</div>&#39;}} )

<div mydir> </div>写成自定义属性                      ----A----属性
-<mydir></mydir>写成元素。注意如果需要改变模板路径里面的内容，就需要使用ng-transclude,然后在模板指令的配置项里写
return {templateUrl :../template.html,transclued:true}          -----E----元素

Error: $compile:iscp

Invalid Isolate Scope Definition
Description
When declaring isolate scope the scope definition object must be in specific format which starts with mode character (@&=<), after which comes an optional ?, and it ends with an optional local name.
myModule.directive(&#39;directiveName&#39;, function factory() {  return {
    ...
    scope: {      &#39;localName&#39;: &#39;@&#39;, // OK
