angular.js - Angular中的directive指令是否能接受object类型的赋值？

Question

我想写一个list
利用directive来写一个item
这个item要根据赋予的不同的值产生相应变化 但目前我只知道简单的数据赋值
例如

.directive('al-item', function() {
    return {
        restrict: 'EA',
        template: '

<p>'
                 +'</p>

',
        replace: true,
        controller: function($scope, $element, $attrs, $transclude) {
            //这里根据a、b、c 三者的值 进一步修饰al-item
        }
    };
})

<al-item a='' b='' c=''>

我希望的形式 更像是

<al-item object=''>

这样提供一个object数据
al-item就能实现我预定的样子
请问这可以实现吗？

You can look at the scope part of the instruction to solve your questions.

Approximately:

html<p ng-controller="cc">
<al-item object="obj"></al-item>
</p>

jsangular.module('xx', [])
.controller('cc', ['$scope', function($scope) {
    $scope.obj = {a:'a', b:'b', 'c':'c'}
}])
.directive('alItem', function() {
    return {
        restrict: 'EA',
        template: '<p>'+'</p>',
        replace: true,
        transclude: true,
        scope: {
            object: "="
        },
        controller: function($scope, $element, $attrs, $transclude) {
            //scope.object 这里就可以判断了
        }
    };
})

Probably like this. For details, you can read the official documentation

Directive scope itself supports three modes
1. "=" any object
2. "&" The external method is passed into the directive and called internally
3. "@" string

Answer 3

The object in HTML is also an attrs. Attrs has been transferred into the function. You can use attrs to call object directly.
