如何在UI-Bootsrap的Tab Nav上替换或添加新类。我期待类似的东西,
<ul class="MY-CUSTOM-CLASS" ng-class="{'nav-stacked': vertical, 'nav-justified': justified}" ng-transclude="">
<li ng-class="{active: active, disabled: disabled}" heading="Justified" class="ng-isolate-scope">
<a href="" ng-click="select()" tab-heading-transclude="" class="ng-binding">Justified</a>
</li>
.....
</ul>
我尝试了以下内容,但是,它正在将该类添加到父级,
<tabset justified="true" class="tab-nav">
<tab heading="Justified">Justified content</tab>
<tab heading="SJ">Short Labeled Justified content</tab>
<tab heading="Long Justified">Long Labeled Justified content</tab>
</tabset>

好的,ui bootstrap模块不支持你不想做的事情,所以我们需要扩展模块以获得所请求的行为。为此,我们将使用装饰器:
.config(function($provide) {
// This adds the decorator to the tabset directive
// @see https://github.com/angular-ui/bootstrap/blob/master/src/tabs/tabs.js#L88
$provide.decorator('tabsetDirective', function($delegate) {
// The `$delegate` contains the configuration of the tabset directive as
// it is defined in the ui bootstrap module.
var directive = $delegate[0];
// This is the original link method from the directive definition
var link = directive.link;
// This sets a compile method to the directive configuration which will provide
// the modified/extended link method
directive.compile = function() {
// Modified link method
return function(scope, element, attrs) {
// Call the original `link` method
link(scope, element, attrs);
// Get the value for the `custom-class` attribute and assign it to the scope.
// This is the same the original link method does for the `vertical` and ``justified` attributes
scope.customClass = attrs.customClass;
}
}
// Return the modified directive
return $delegate;
});
});
这将采用tabset指令的旧link
方法,并使用自定义方法对其进行包装,除了旧方法之外,还将custom-class
属性的值绑定到范围。我们需要做的第二件事是覆盖模板以实际使用scope.customClass
参数:
有多种方法可以使用$templateProvider
或者更简单的方式使用<scrip type="text/ng-template">
:
<script id="template/tabs/tabset.html" type="text/ng-template">
<div>
<ul class="{{customClass}} nav nav-{{type || 'tabs'}}" ng-class="{'nav-stacked': vertical, 'nav-justified': justified}" ng-transclude></ul>
<div class="tab-content">
<div class="tab-pane" ng-repeat="tab in tabs" ng-class="{active: tab.active}" tab-content-transclude="tab">
</div>
</div>
</div>
</script>

不确定这是否会有所帮助..
您可以使用ng-class指令添加一个类:
<强> HTML:
<div ng-class="divClass"></div>
<强> JS:
$scope.divClass = 'class-name other-class-name';
如果您不希望该类只用空字符串替换变量的值。
