angularjs一个元素的两个指令 [英] angularjs two directives on one element

问题描述

我有两个指令：

// Generated by CoffeeScript 1.6.3
app.directive("focusMe", function() {
  return {
    scope: {
      focus: "=focusMe"
    },
    link: function(scope, element) {
      return scope.$watch("focus", function(value) {
        if (value === true) {
          element[0].focus();
          return scope.focus = false;
        }
      });
    }
  };
});

和

// Generated by CoffeeScript 1.6.3
app.directive("cleanMe", function() {
  return {
    scope: {
      clean: "=cleanMe"
    },
    link: function(scope, element) {
      return scope.$watch("clean", function(value) {
        if (value === true) {
          element[0].value = "";
          return scope.clean = false;
        }
      });
    }
  };
});

和此输入（angularUI）：

and this input (angularUI):

<input type="text" ng-model="addUserSelected" typeahead="emp.value for emp in allUsers | filter:$viewValue | limitTo:5" typeahead-editable="false" typeahead-on-select="addLine($item.id)" focus-me="usersFocusInput" clean-me="usersCleanInput">

我得到这个错误：

I get this error:

Error: [$compile:multidir] http://errors.angularjs.org/1.2.3/$compile/multidir?p0=cleanMe&p1=focusMe&p…2%20focus-me%3D%22usersFocusInput%22%20clean-me%3D%22usersCleanInput%22%3E

我做错了怎么办？

what do I do wrong?

如果我从它的工作原理HTML去除干净我属性。

If I remove the clean-me property from the html it works.

感谢

推荐答案

我找到了解决办法最后：）

I found the solution finally :)

// Generated by CoffeeScript 1.6.3
app.directive("focusMe", function() {
  return {
    link: function(scope, element, attributes) {
      return scope.$watch(attributes.focusMe, function(value) {
        if (scope[value] === true) {
          element[0].focus();
          return scope[attributes.focusMe] = false;
        }
      });
    }
  };
});

// Generated by CoffeeScript 1.6.3
app.directive("cleanMe", function() {
  return {
    link: function(scope, element, attributes) {
      return scope.$watch(attributes.cleanMe, function(value) {
        if (value === true) {
          element[0].value = "";
          return scope[attributes.cleanMe] = false;
        }
      });
    }
  };
});

在HTML usersFocusInput和usersCleanInput都在范围参数是西隧我使用的范围[attributes.focusMe]获得此参数并改变他为false。

In the html usersFocusInput and usersCleanInput are parameters in the scope that is wht I use scope[attributes.focusMe] to get this parameter and change him to false.

<input type="text" ng-model="addUserSelected" typeahead="emp.value for emp in allUsers | filter:$viewValue | limitTo:5" typeahead-editable="false" typeahead-on-select="addLine($item.id)" focus-me="usersFocusInput" clean-me="usersCleanInput">
