Question

在我的程序中，我想使用变量设置ng-show值，因此我随时更改ng-show。

角度代码是：

  var arrowup,arrowdown;
  arrdown=false;
  $scope.header=[{"name":"Subsection Header #1","arrowup":"arrowup","close":"close","arrowdown":"arrowdown","open":"open"}];

  $scope.open = function() {
        arrowdown = false;
        arrowup = true;
      }

我希望更改ng-show的值，但不会更改。

html代码是：

  <div class="arrow-down" ng-repeat="header in header"   ng-click="this[header.open]()"    ng-show="header.arrowdown ">

Answer 1

您不能在Angular中使用绑定到模板，而是使用$scope。

此外，您不能使用同名的ng-repeat。

最后，没有必要将this[header.open]()放在ng-click中，只需使用open()。

$scope.arrowdown=false;
$scope.header=[{"name":"Subsection Header #1","arrowup":"arrowup","close":"close","arrowdown":"arrowdown","open":"open"}];

$scope.open = function() {
    $scope.arrowdown = false;
    $scope.arrowup = true;
}

<div class="arrow-down" ng-repeat="head in header" ng-click="open()"    ng-show="head.arrowdown">

Answer 2

此代码将在点击时切换显示：

  $scope.headers=[{"name":"Subsection Header #1","arrowup":"arrowup","close":"close","arrowdown":"arrowdown","open":"open", show: false}];

  $scope.open = function(header) {
        header.show = !header.show;
      }

<div class="arrow-down" ng-repeat="header in headers"   ng-click="open(header)"    ng-show="header.show">

目前尚不清楚你真正想要的是什么，我为你创造了样本：

＆＃13;

ToString("dd-MMM-yyyy HH:mm:ss",CultureInfo.InvariantCulture);

＆＃13;

import UIKit
import Foundation

struct Player
{
    var name:String?
    var game:String?
    var rating:Int

    init(name:String?, game:String?,rating:Int)
    {
        self.name = name
        self.game = game
        self.rating = rating
    }
}

let playersData = [
Player(name: "Bill Evans", game: "TTT", rating: 4),
Player(name: "OD", game: "Spin the Bottle", rating: 5),
Player(name: "DB", game: "Texas Holder", rating: 2)]



class PlayersViewController: UITableViewController {

var players:[Player] = playersData


override func viewDidLoad() {
    super.viewDidLoad()

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

// MARK: - Table view data source

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {

    return 1
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return players.count
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{

    //This method will check to see if there is an existing cell that can be recycled.If not, it will automatically allocate a prototype cell and return it to you.
    let cell = tableView.dequeueReusableCellWithIdentifier("PlayerCell", forIndexPath: indexPath)


    let player = players[indexPath.row]as Player
    cell.textLabel?.text = player.name
    cell.detailTextLabel?.text = player.game
    return cell

   }
}

＆＃13;

我想使用ng-repeat数组值设置ng-show
