尝试创建AngularJS指令时出现模板错误

Question

我正在尝试创建一个将创建以下HTML的指令,所以我不必在很多地方继续写这个:

    <div class="activity-mask" data-ng-show="loading!=0">
        <span>Loading... {{ loading }}</span>
    </div>
    <div class="activity-mask" data-ng-show="fetching!=0">
        <span>Fetching... {{ fetching }}</span>
    </div>

这是我尝试过的:

 app.directive('myActivity', function() {
    return {
        restrict: "A",
        template: "<div class='activity-mask' data-ng-show='loading!=0'>" +
                   "<span>Loading... {{ loading }}</span>" + 
                   "</div>" +
                   "<div class='activity-mask' data-ng-show='fetching!=0'>" +
                   "<span>Fetching... {{ fetching }}</span>" +
                   "</div>",
        replace: true
    };
});

但是,这给了我以下错误:

Answer 1

答案在错误堆栈本身.只需按照错误描述链接:

http://docs.angularjs.org/error/$compile:tplrt?p0=myActivity

使用replace: true模板时需要有一个根节点.你的有两个.
