In Polymer 0.5, one could use the tokenList filter with expressions on an elements class attribute to apply classes conditionally based on object values. What is the v1.0 replacement or equivalent technique? I can't find anything on the subject beyond handling it entirely in code. Polymer 1.0 made quite a few cuts in favor of performance gains, expressions being one of those. Using the
在Polymer 0.5中，可以使用带有元素类属性表达式的tokenList过滤器来根据对象值有条件地应用类。 什么是v1.0替代或等效技术？ 除了完全用代码处理它之外，我无法找到任何有关该主题的内容。 聚合物1.0为了提高性能而做了一些削减，表达式就是其中之一。 使用0.5文档中的示例： <div class="{{ {active: user.selected, big: user.type == 'super'} | tokenList}}"> 你可以重写1.0，如下所示： <div class$="{{g

我有像侧栏导航这样的垂直手风琴。 一切工作正常，但我正面临着一些问题与我从Twitter Bootstrap 3使用它的图标。 这是FIDDLE 。 当我展开一个列表项时，我希望图标朝下，当我再次单击它时，它不会折叠。 而且我还希望将图标更改为左面chevron图标。 另外，请帮助我添加过渡效果，就像它即将展开时那样，我希望从面朝左到朝下的动画效果。 而且，只有当我点击文字时，我才能展开菜单。 我无法做到这一点。 提前致谢

I have the following JavaScript object: var obj = { "key1" : val, "key2" : val, "key3" : val } Is there a way to check if a key exists in the array, similar to this? testArray = jQuery.inArray("key1", obj); does not work. Do I have to iterate through the obj like this? jQuery.each(obj, function(key,val)){} Use the in operator: testArray = 'key1' in obj; Sidenote: What you go
我有以下JavaScript对象： var obj = { "key1" : val, "key2" : val, "key3" : val } 有没有办法检查数组中是否存在键，类似于这个？ testArray = jQuery.inArray("key1", obj); 不起作用。 我是否必须像这样迭代obj？ jQuery.each(obj, function(key,val)){} 使用in运算符： testArray = 'key1' in obj; 旁注：你到那里，实际上是没有jQuery对象，但只是一个普通的JavaScript对象。 这不是一个jQuery对
