问题是child指令绑定到parent,但{{name}}
忽略了语法ng-repeat
。实现这一目标的正确方法是什么?
HTML(主要/子指令)
<compact-select
no-item-selected-text="Add a Customer"
no-item-selected-icon="fa-user"
search-placeholder="Type a customer name"
cs-model="customer"
cs-items="contacts"
>
<display-item-template>
<span>{{name}}</span>
or
<span>{{item.name}}</span>
</display-item-template>
</compact-select>
指令
angular.module('core').directive('compactSelect', [function($timeout) {
return {
templateUrl : 'modules/core/views/components/compact-select-tpl.html',
bindToController: true,
transclude: true,
scope: {
noItemSelectedText: '@',
noItemSelectedIcon: '@',
csModel: '=',
csItems: '=csItems'
},
controllerAs : 'ctrl',
controller : function($scope) {
}
};
}]).directive('displayItemTemplate', function($timeout) {
return {
require: '^compactSelect',
restrict: 'E'
}
});
指令模板(modules / core / views / components / compact-select-tpl.html)
<div class="compact-select-repeater-box" style="" >
<div ng-transclude ng-repeat="item in ctrl.csItems | filter:searchParam" class="compact-select-repeater" ng-class="ctrl.getHighlightedClass(item)" ng-click="ctrl.itemSelected(item)">
<span>{{item.name}}</span>
<span>{{item.id}}</span>
</div>
<div style="position:absolute;bottom:0">
<a href="#">+ Click here to add customer {{ctrl.message}}</a>
</div>
</div>
我可以看到
<span>{{item.name}}</span>
<span>{{item.id}}</span>
替换为
<span></span>
or
<span>{{item.name}}</span>
而不是
<span>{{name}}</span>
or
<span>{{item.name}}</span>
问题:如何让ng-repeat
尊重来自child指令的html绑定语法?或者还有另一种方法来实现这一目标吗?

如果我没有错,那么您正在尝试创建list view
,以便用户提供列表的template
,但方法(点击等)已经是通过指令提供。
现在,由于angular 1.3
,transcluded scope
是directive isolated scope
的孩子,
因此,在您的情况下,如果您遵循正确的层次结构,则可以从用户提供的模板中访问directive scope
。
以下是您的范围层次结构:
Directive isolated scope
- &gt; ng-repeat new scope for every row
- &gt; transcluded scope
。
因此,如果您想从directive scope
访问transcluded scope
,
您需要执行$parent
(对于ng-repeat),然后访问item.name
,如下所示:
<display-item-template>
<span>Item Name: {{$parent.item.name}}</span>
</display-item-template>
此外,您不需要compact-select-tpl
内的绑定,因为您希望该内容来自翻译:
<div class="compact-select-repeater-box" style="" >
<div ng-transclude ng-repeat="item in ctrl.csItems | filter:searchParam"
class="compact-select-repeater"
ng-class="ctrl.getHighlightedClass(item)"
ng-click="ctrl.itemSelected(item)">
<!-- <span>{{item.name}}</span>
<span>{{item.id}}</span> -->
</div>
<div style="position:absolute;bottom:0">
<a href="#">+ Click here to add customer {{ctrl.message}}</a>
</div>
</div>

您在另一个指令中转换的displayItemTemplate
指令已经插入了数据{{name}}
和{{item.name}}
。
如果$ scope中没有这些变量,它会在你的跨度内转换空字符串。
然后在你的compactSelect
指令中,被转换的div将覆盖它的内容。
如果在另一个指令的模板中移动displayItemTemplate
指令,则重复将起作用。 (您需要删除ng(transclude和transclude:true
此外,如果您使用bindToController
,请不要将属性放在范围内。
function compactSelect() {
return {
template : [
'<div class="compact-select-repeater-box" style="" >',
'<div ng-repeat="item in ctrl.csItems | filter:searchParam" class="compact-select-repeater" ng-class="ctrl.getHighlightedClass(item)" ng-click="ctrl.itemSelected(item)">',
'<display-item-template>',
'<span>{{item.name}}</span>',
'</display-item-template>',
'</div>',
'<div style="position:absolute;bottom:0">',
'<a href="#">+ Click here to add customer {{ctrl.message}}</a></div></div>',
].join(''),
bindToController: {
noItemSelectedText: '@',
noItemSelectedIcon: '@',
csItems: '=csItems'
},
scope: {},
controllerAs : 'ctrl',
controller : function($scope) {
}
}
}
function displayItemTemplate() {
return {
require: '^compactSelect',
restrict: 'E'
}
}
function SuperController() {
this.name = "a name";
this.contacts = [{name:"rob"}, {name:"jules"}, {name:"blair"}];
}
angular.module('myApp', []);
angular
.module('myApp')
.controller('SuperController', SuperController)
.directive('compactSelect', compactSelect)
.directive('displayItemTemplate', displayItemTemplate);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
<div ng-app="myApp">
<div ng-controller="SuperController as s">
<compact-select
no-item-selected-text="Add a Customer"
no-item-selected-icon="fa-user"
search-placeholder="Type a customer name"
cs-items="s.contacts">
</compact-select>
</div>
</div>
