我正在尝试完成以下方案:
我有以下指令:
return {
restrict: "AE",
replace: true,
transclude: true,
scope: {
chartData: "=",
groupId: "@",
groupName: "@"
},
template: "<div class=\"flex\" ng-transclude></div>",
compile: function(){
var charts = [];
return function (scope, element, attributes, controller, transcludeFn) {
_.forEach(scope.chartData, function (data) {
var id = "gauge-" + scope.groupId + '-' + data.name;
scope[id] = data.value; // gauge directive can now access this value
element.append("<div class=\"flex-spacer flex-column\"><div bv-gauge chart-title=\"" + data.name + "\" data-value=\"" + scope[id] + "\" series-name=\"" + scope.groupName + "\"></div></div>");
charts.push(id);
});
$compile(element.contents())(scope);
scope.$watch("chartData", function (newVal) {
_.forEach(scope.chartData, function (data) {
var id = "gauge-" + scope.groupName + '-' + data.name;
scope.$broadcast("chart:update", newVal);
});
});
}
}
};
正如您所看到的,我正在动态地将一些内容添加到指令的元素中。它工作得很好,但有一个问题;内部指令的孤立范围(即bv-gauge)只能看到外部范围而不是bv-gauge-parent的范围;据我所知,这是默认行为,我们可以使用transclude函数覆盖它。
但是,似乎angular不会将动态添加的内容视为已转换内容的一部分。所以当我做以下事情时:
transcludeFn(scope, function(clone, scope){
// clone doesn't have the content we added earlier
});
有没有办法将已转换内容的范围与父指令相关联?
