ng-Class - 多个条件和类

Question

我一直在寻找ng-class中多个条件的例子,但我找不到使用相同的术语.这是我想要实现的一个例子.

ng-class ="isSelected？'side_menu_link_active':'side_menu_link_disabled',pageSelected =='lectures'？'link_active':'link_disabled'"

有谁知道这个的正确语法？谢谢.

如果您想要多个条件,则语法为:

ng-class=" {className: valueToCheckForTruthiness, otherClassName: otherValue  } " 

使用您的类名的示例:

ng-class="{side_menu_link_active: isSelected, side_menu_link_disabled: !isSelected, link_active: pageSelected == 'lectures', link_disabled: pageSelected != 'lectures'   }"

您可以进一步使用函数生成对象:

$scope.classGenerator = function(isSelected, pageSelected){
     var obj = {};
     isSelected ? obj.side_menu_link_active=true : obj.side_menu_link_disabled = false;
     pageSelected == 'lectures' ? obj.link_active = true : obj.link_disabled = false;
     return obj;
}
ng-class="classGenerator(isSelected, pageSelected)"
