任何想法如何从指令内部访问属性值？
angular.module('portal.directives',[])
.directive('languageFlag',['$routeParams',function(params) {
return function(scope,element,attrs) {
console.log(attrs["data-key"]); // returns undefined
console.log(element.attr('data-key')); // returns {{data-key}}
angular.element(element).css('border','1px solid red');
};
}]);
HTML代码是：
<ul>
<li ng-repeat="lng in flags">
<a class="lngFlag {{flag.Key}}" data-key="{{flag.Key}}" data-id="{{lng.Id}}" ng-click="changeLangHash({'lng':lng.Id })" language-flag></a>
</li>
</ul>
谢谢
使用$观察：
Observing interpolated attributes: Use
$observeto observe the value changes of attributes that contain interpolation (e.g.src="{{bar}}"). Not only is this very efficient but it’s also the only way to easily get the actual value because during the linking phase the interpolation hasn’t been evaluated yet and so the value is at this time set toundefined. — 07000
return function(scope,attrs) {
attrs.$observe('key',function(value) {
console.log('key=',value);
});
}
