我有一个指令,它将元素放在一个独立的作用域上并对它应用一个控制器,因此它可以处理状态,AJAX调用和验证。
<div login>
<div class="dropdown" ng-click="loginctrl.showForm()">
Login <span class="caret"></span>
</div>
</div>
当前被转换的元素变为:
<!-- login -->
<div class="login">
<div class="dropdown" ng-click="loginctrl.showForm()">
Login <span class="caret"></span>
</div>
</div>
但是我有一个templateUrl
我想要附加指令的内容,所以我使用transclude: 'element'
来细化转换:
angular
.module('Login.module', [])
.controller('LoginCtrl', function(){
this.login = function(){
// do ajax calls for login
};
this.logout = function(){
// do ajax calls for logout
};
this.facebook = function(){
// do ajax calls for facebook login
};
this.showForm = function(){
// shows the template form
};
this.user = {}; // user model
})
.directive('login', function(){
return {
restrict: 'A',
transclude: 'element',
controllerAs: 'loginctrl',
controller: 'LoginCtrl',
replace: false,
templateUrl: '/templates/login',
link: function(scope, element, attrs, ctrl, transclude){
transclude(scope, function(clone){
clone.wrap('<div class="login"></div>');
element.after(clone); // "element" is the <!-- login --> HTML comment
// "clone" is the transcluded contents of the div, that is the login with ng-click, etc
});
}
}
});
templateUrl
(即登录/注册表单)是通过AJAX下载的(在开发工具中查看),但它不能在链接函数内部使用,也不能在转换中使用。我错过了什么吗?在这方面找不到任何帮助,我现在已经找了几天。

我已使用以下内容更新this plnkr,我认为这样做符合您的要求。我已经对正在发生的事情做了一些补充说明。
.directive('login', function() {
var useElementTransclusion = true;
var replace = true;
return {
restrict: 'A',
transclude: useElementTransclusion ? 'element' : true,
controllerAs: 'loginctrl',
controller: 'LoginCtrl',
replace: useElementTransclusion ? true : replace,
templateUrl: 'login.html',
link: function(scope, element, attrs, ctrl, transclude) {
// If transclude is 'element', then the element argument is
// the HTML comment which is put in the place of the entire
// element on which the directive was applied.
// If transclude is true, then the element argument depends
// on the value of replace. If replace is true then element
// is the content of the template. If replace is false then
// element is the element on which the directive was applied.
transclude(scope, function(clone) {
// If transclude is 'element' then clone is an array
// containing the single element on which the directive
// was applied.
// If transclude is true then clone is an array containng
// the children of the element on which the directive was
// applied.
element.wrap('<div class="login"></div>');
element.after(clone);
});
}
}
});
如果您使用transclude; 'element'
,则必须使用replace: true
,以获得某些解释see this issue。如果您使用transclude: true
,则可以使用replace
所需的任何值,具体取决于您对应用该指令的原始HTML节点所需的最终结果(是否仍然存在) )。
以下是原始答案,没有特别原因留在这里......
不完全确定这是否会产生您期望的确切结果,但是......
.directive('login', function() {
return {
restrict: 'A',
transclude: 'element',
controllerAs: 'loginctrl',
controller: 'LoginCtrl',
replace: true,
templateUrl: '/templates/login',
link: function(scope, element, attrs, ctrl, transclude) {
transclude(scope, function(clone) {
element.after(clone);
clone.wrap('<div class="login"></div>');
});
}
};
})
变化是:
