Question

我正在研究角度bootstrapUI手风琴，我需要捕捉每个部分的切换事件，例如，在每个部分的标题中，我有一个箭头，当它打开时箭头向下会显示，和其他其他部分的箭头将显示向右箭头。这样的东西：

<accordion-group  is-open="true"  ng-repeat="destination in mileage.destionations">
            <accordion-heading>
                <span ng-class="{'fa-chevron-down': openEvent, 'fa-chevron-right': !openEvent">Toggle Me</span>
            </accordion-heading>
               <div class='accordion-section'>
                    Main content here
                </div>
        </accordion-group>

如您所见，如何为手风琴组中的每个部分切换fa-chevron-down和fa-chevron-right类？

你真的很亲密......

将您的// // ViewController.m // REST // // Created by Grant Zukel on 8/5/15. // Copyright © 2015 Grant Zukel. All rights reserved. // #import "ViewController.h" @import GoogleMaps; @interface ViewController () { } @end @implementation ViewController{ GMSMapView *mapView_; @public NSInteger int_lat; @public NSInteger int_lon; } - (IBAction)drawMap; { NSURL *url = [NSURL URLWithString:@"http://127.0.0.1:8001/test/39.748922&-104.986147"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) { if (data.length > 0 && connectionError == nil) { NSDictionary *greeting = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL]; //NSLog([greeting objectForKey:@"status"]); self.greetingContent.text = [greeting objectForKey:@"content"]; self.greetingId.text = [greeting objectForKey:@"id"]; NSString *latitude = ([[greeting objectForKey:@"coords"] objectForKey:@"latitude"]); NSString *longitude = ([[greeting objectForKey:@"coords"] objectForKey:@"longitude"]); self.testLat.text = latitude; self.testLon.text = longitude; int_lat = [latitude intValue]; int_lon = [longitude intValue]; } }]; GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:int_lat longitude:int_lon zoom:1]; mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera]; mapView_.myLocationEnabled = YES; self.view = mapView_; GMSMarker *marker = [[GMSMarker alloc] init]; marker.position = CLLocationCoordinate2DMake(int_lat, int_lon); marker.title = @"Test"; marker.snippet = @"Test"; marker.map = mapView_; } - (void)viewDidLoad { [super viewDidLoad]; [self drawMap]; //NSString *temperatureString = [self getStringForTemperature:A base:B]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end更改为属性名称，而不是值。其他人看起来is-open始终处于打开状态（is-open）。

所以这样：

true

现在，当开放<accordion-group is-open="isOpen" ng-repeat="destination in mileage.destionations"> <accordion-heading> <span ng-class="{'fa-chevron-down': isOpen, 'fa-chevron-right': !isOpen">Toggle Me</span> </accordion-heading> <div class='accordion-section'> Main content here </div> </accordion-group>设置为isOpen时。关闭后，它将设置为true，图标切换功能将起作用。

false可以是你喜欢的任何东西。它只是一个isOpen属性，将被创建和设置。因此，您可以使用$scope并在is-open="iAmOpenNow"中使用iAmOpen：）
