Question

在我的AngularJS / Ionic应用程序中，我编写了一个带有包含JSON Schema URN的元素的自定义参数的指令。问题是AngularJS尝试将此URN评估为表达式。

<myDirective myAttr="urn:jsonschema:net:example:net:myschema"></myDirective>

错误：

Error: [$parse:syntax] http://errors.angularjs.org/1.2.25/$parse/syntax?p0=%3A&p1=is%20an%20unexpected%20token&p2=4&p3=urn%3Ajsonschema%3Anet%3Aexample%3Anet%3Amyschema&p4=%3Ajsonschema%3Anet%3Aexample%3Anet%3Amyschema

如何阻止AngularJS解析我的属性？

修改：将架构的属性名称更改为 myAttr ，因为架构已保留。导致同样的错误。

使用text @ binding：

app.directive('myDirective', function () {
    return {
      restrict: 'E',
      scope: {
          myAttr: "@"
       },
       link: function (scope) {
          console.log(scope.myAttr);
        }
      };
    }
);

HTML：

<my-directive my-attr="urn:jsonschema:net:example:net:myschema"></my-directive>

将URN传递给参数时，AngularJS会引发错误
