use*_*600 15 optgroup angularjs
我正在使用angularjs,我一直在努力创建一个过去2天的optgroup,同时处理其他一些东西,我很难过.我不得不创建一个ng-options,但直到我意识到我需要一个选项组才考虑.我尝试使用ng-options将其添加进去,但它会完全忽略它,弄乱代码或完全忽略选项.
我不知道我是否真的可以使用(双)&符号,所以我尝试结合两个ng-options,但无济于事.此外,我玩弄了odetocode中的特定代码(这似乎很有希望,但由于其自身有限的结构,无法与我的代码合并).
我试过的一切都破坏了我的代码.原始代码在下面(我的许多其他mod之前的代码),但我也有它的plunker:

不确定你想要将它们分组,所以我添加了一个额外的属性type
:
句法:
ng-options="option.name as option.value group by option.type for option in options"

AngularJS文档中有一个很好的例子,如果您想对选项的属性进行分组,则可以添加“ group by”子句。例如:
$scope.options = [
{ name:'test', namegroup: 'Rate the product', value:'test2',valueName: 'NA' },
{ type: 'one', name: '1 star', value: '1 star' },
{ type: 'one', name: '2 stars', value: '2 stars' },
{ type: 'two', name: '3 stars', value: '3 stars' },
{ type: 'two', name: '4 stars', value: '4 stars' },
{ type: 'two', name: '5 stars', value: '5 stars' }
];

以及ng-options:
"option.name as option.value group by option.type for option in options"
