角度js如何在自定义指令上观察属性，以接受角度值来绑定
这是我到目前为止
<tile title="Sleep Duration" data-value="{{sleepHistory.averageSleepTime}}"/>
app.directive('tile',[function() {
return {
restrict: 'E',link: function(scope,element,attrs) {
var title = attrs.title;
attrs.$observe('dataValue',function(val) {
var data = val;
console.log(data);
var dom =
"<div>" +
"<p>" + title + "</p>" +
"<p>" + data + "</p>" +
"</div";
$(element).append($(dom.trim()));
});
}
};
}]);
但是观察到的价值是未定义的
从
http://docs.angularjs.org/api/ng.$compile.directive.Attributes：
all of these are treated as equivalent in Angular:
<span ng:bind="a" ng-bind="a" data-ng-bind="a" x-ng-bind="a">
所以属性数据值归一化为值
所以，这就是你想要的：
attrs.$observe('value',function(val) {
