我正在尝试构建此处的菜单:
然而,当我将其实现到我的项目中时,我收到以下错误消息:
Syntax Error: Token 'node.click' is unexpected, expecting [:] at column 3 of the expression [{{node.click}}] starting at [node.click}}].
我得到的结果是我可以看到菜单项名称,但是当我将鼠标悬停在它们上面时,我会收到一个空的菜单框?
以下是我的HTML指令:
app.directive('navMenu', ['$parse', '$compile', function ($parse, $compile) {
return {
restrict: 'C', //Element
scope: true,
link: function (scope, element, attrs) {
scope.selectedNode = null;
scope.$watch(attrs.menuData, function (val) {
var template = angular.element('<ul id="parentTreeNavigation"><li ng-repeat="node in ' + attrs.menuData + '" ng-class="{active:node.active && node.active==true, \'has-dropdown\': !!node.children && node.children.length}"><a ng-href="{{node.href}}" ng-click="{{node.click}}" target="{{node.target}}" >{{node.text}}</a><sub-navigation-tree></sub-navigation-tree></li></ul>');
var linkFunction = $compile(template);
linkFunction(scope);
element.html(null).append(template);
}, true);
}
};
}]);
app.directive('subNavigationTree', ['$compile', function ($compile) {
return {
restrict: 'E', //Element
scope: true,
link: function (scope, element, attrs) {
scope.tree = scope.node;
if (scope.tree.children && scope.tree.children.length) {
var template = angular.element('<ul class="dropdown "><li ng-repeat="node in tree.children" node-id={{node.' + attrs.nodeId + '}} ng-class="{active:node.active && node.active==true, \'has-dropdown\': !!node.children && node.children.length}"><a ng-href="{{node.href}}" ng-click="{{node.click}}" target="{{node.target}}" ng-bind-html-unsafe="node.text"></a><sub-navigation-tree tree="node"></sub-navigation-tree></li></ul>');
var linkFunction = $compile(template);
linkFunction(scope);
element.replaceWith(template);
} else {
element.remove();
}
}
};
}]);
app.controller('HeaderController', ['$scope', '$location', function ($scope, $location) {
$scope.breadcrumbs = [];
$scope.menu = [{
text: 'HOME',
href: '/app/index.html',
children: [{
text: 'MANAGE Dashboard',
href: '/dashb'
}]
}, {
text: 'MANAGE',
href: '/manage',
children: [{
text: 'MANAGE PEOPLE',
href: '/manage-people',
children: [{
text: 'MANAGE STAFF',
href: '/manage-staff'
}, {
text: 'MANAGE CLIENTS',
href: '/manage-clients'
}]
}]
}, {
text: 'REPORTS',
href: '/reports',
children: [{
text: 'REPORT NUMERO UNO',
href: '#'
}, {
text: 'REP NUMERO 2',
href: '#',
children: [{
text: 'Third Tier',
href: '#'
}, {
text: 'Another Third Tier',
href: '#',
children: [{
text: 'SUB SUB NAV',
href: '#'
}]
}]
}]
}, {
text: 'MY INFO',
href: '/my-info'
}, ]
}]);
<div class="row">
<div class="large-12 columns">
<nav class="nav-menu" menu-data="menu"></nav>
</div>
</div>

问题是您使用的是ng-bind-html-unsafe
已被弃用的Angular 1.2+版本,您应该将其替换为ng-bind-html
,然后您需要使用$sce
服务使用{{}来清理该html 1}}方法。
为此,您应该编写自定义过滤器,并将该过滤器应用于您想要显示HTML的位置
$sce.trustedAsHtml
然后在你的html中,它将被用作app.filter('unsafe', function($sce) {
return $sce.trustAsHtml;
});

我通过在链接中添加{{node.text}}来修复此问题,因为没有什么我没想到检查它,因为它在小提琴上以某种方式工作。
