angular的自定义指令如何使用

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

<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('directiveName', function factory() {  return {
    ...
    scope: {      'localName': '@', // OK
      'localName2': '&attr', // OK
      'localName3': '<?attr', // OK
      'localName4': ' = attr', // OK
      'localName5': ' =*attr', // OK      
      'localName6': 'attr',    // ERROR: missing mode @&=<
      'localName7': 'attr=',   // ERROR: must be prefixed with @&=<
      'localName8': '=attr?',  // ERROR: ? must come directly after the mode
      'localName9': '<*'  // ERROR: * is only valid with =
    }
    ...
  }
});
