ng-repeat: populate drop down options with array
提问by Josue Espinosa
I have a simple JavaScript object that looks like this:
我有一个简单的 JavaScript 对象,如下所示:
$scope.obj = { "'Architect'": ["asdf","d","e","y"]};
I'd like to show the values of 'Architect'in a select box. However, the single quotes are throwing me off when trying to do the ng-repeat.
我想'Architect'在选择框中显示 的值。但是,在尝试执行ng-repeat.
<select>
<option ng-repeat="row in obj['Architect']" value="{{row}}">{{row}}</option>
</select>
That does not populate the select box, it just shows an empty select box. I assume it is interpreting the single quotes as a string literal, but even if I add single quotes and escape them, it still doesn't work as expected. Am I missing something?
这不会填充选择框,它只显示一个空的选择框。我假设它将单引号解释为字符串文字,但即使我添加单引号并转义它们,它仍然无法按预期工作。我错过了什么吗?

why don't you use "ng-options" for select? take a lock at this AngularJs API: select
为什么不使用“ng-options”进行选择?锁定这个 AngularJs API:选择
