我正在使用AngularJS创建一个具有几种不同类型按钮的菜单。根据按钮的类型,html需要具有不同的特征。此外,当前选择的菜单项需要具有与可用按钮不同的颜色。目前,我正在使用这一堆代码:
<div id="navbar" ng-show="navbar.show" ng-mouseenter="navbar.keep()" ng-mouseleave="navbar.release()">
<div ng-repeat="navSection in navbar.navSections" ng-init="sectionIndex = $index" class="navblock">
<div ng-repeat="navItem in navSection.navigationItems">
<div ng-switch on="navItem.function">
<div ng-switch-when='CategoryNav', ng-click='navbar.navClick(sectionIndex, $index)'>
<div info="navItem", ng-if='sectionIndex == navbar.section && $index == navbar.item', id="selected">
<a ui-sref="{{navItem.function}}" ng-href="{{navItem.function}}">
<div class="navbutton">{{navItem.label}}</div>
</a>
</div>
<div info="navItem", ng-if='sectionIndex != navbar.section || $index != navbar.item', id="notselected">
<a ui-sref="{{navItem.function}}" ng-href="{{navItem.function}}">
<div class="navbutton">{{navItem.label}}</div>
</a>
</div>
</div>
<div ng-switch-when='StorefrontNav', ng-click='navbar.changeStorefront(navItem.type)'>
<div info="navItem", id="notselected">
<a ui-sref="{{navItem.function}}" ng-href="{{navItem.function}}">
<div class="navbutton">{{navItem.label}}</div>
</a>
</div>
</div>
<div ng-switch-default>
<div info="navItem", ng-if='sectionIndex == navbar.section && $index == navbar.item', id="selected">
<a ui-sref="{{navItem.function}}" ng-href="{{navItem.function}}">
<div class="navbutton">{{navItem.label}}</div>
</a>
</div>
<div info="navItem", ng-if='sectionIndex != navbar.section || $index != navbar.item', id="notselected">
<a ui-sref="{{navItem.function}}" ng-href="{{navItem.function}}">
<div class="navbutton">{{navItem.label}}</div>
</a>
</div>
</div>
</div>
</div>
</div>
</div>
它工作正常,但我想清理一下。我已经考虑过制作一个指令并传递不同链接需要工作的函数(例如,navbar.changeStoreFront()
),但这似乎只是为了清理格式一些额外的代码。有谁知道更好的方法来清理它?

我注意到使代码更具可读性的最简单方法是将属性放在不同的行上。以此为例:
Delegate Sub MyDelegate(ByVal input As String)
Sub MyDelegateDefault(ByVal input As String)
'by default do nothing'
End Sub
Sub MyDelegateCustom1(ByVal input As String)
'do something here'
End Sub
