OrderBy boolean value with AngularJS ng-repeat
提问by Adam K Dean
I'd like to be able to sort by whether a variable is true or false.
我希望能够按变量是真还是假进行排序。
Let's say we have a variable like so:
假设我们有一个像这样的变量：
groups = {
{ name: 'first', value: true },
{ name: 'second', value: false },
{ name: 'third', value: true },
{ name: 'fourth', value: false }
}
And we can loop through it like so:
我们可以像这样循环遍历它：
<div ng-repeat="group in groups">
{{group.name}} {{group.value}}
</div>
Which will give you the following:
这将为您提供以下信息：
first true
second false
third true
fourth false
But if I wanted to sort by a boolean valuethen I could do this:
但是如果我想按布尔值排序，那么我可以这样做：
<div ng-repeat="group in groups | filter:{value:true}">
{{group.name}} {{group.value}}
</div>
<div ng-repeat="group in groups | filter:{value:false}">
{{group.name}} {{group.value}}
</div>
Which would give me the following output (which I want):
这会给我以下输出（我想要的）：
first true
third true
second false
fourth false
Is there a way to do this using orderByor filterin a single ng-repeat?
有没有办法使用orderBy或filter在单个中做到这一点ng-repeat？
回答by SethWhite
orderBy accepts and sorts by booleans.
orderBy 接受布尔值并按布尔值排序。
Order the repeated element by the the 'value' property of 'group':
通过 'group' 的 'value' 属性对重复元素进行排序：
ng-repeat="group in groups | orderBy: 'value'"
This will reverse the order:
这将颠倒顺序：
ng-repeat="group in groups | orderBy: '-value'"
If you would like to also sort by the 'name' property of 'group':
如果您还想按 'group' 的 'name' 属性排序：
ng-repeat="group in groups | orderBy: ['value','name']"

use variable name instead obeject
使用变量名而不是对象
orderBy:'Event':false
you will get the desired output like -
您将获得所需的输出，例如 -
first true
third true
second false
fourth false
