我怎样才能避免{{f = ...}}第三行语句打印出内容forecast[day.iso]?
我想避免使用forecast[day.iso].temperature每次迭代依此类推。
<div ng-repeat="day in forecast_days">
{{$index}} - {{day.iso}} - {{day.name}}
{{f = forecast[day.iso]}}
Temperature: {{f.temperature}}<br>
Humidity: {{f.humidity}}<br>
...
</div>
Use ngInit: https://docs.angularjs.org/api/ng/directive/ngInit https://docs.angularjs.org/api/ng/directive/ngInit
<div ng-repeat="day in forecast_days" ng-init="f = forecast[day.iso]">
{{$index}} - {{day.iso}} - {{day.name}}
Temperature: {{f.temperature}}<br>
Humidity: {{f.humidity}}<br>
...
</div>
