Question

我使用angularjs框架，我创建了一个form.html和一个带有变量的controller.js，用于检索框的SSID。如何在表单中自动分配变量的值。这是一个输入字段。启动应用程序时，表单应自动显示SSID，而无需用户这样做。

$scope.SSID {}; return [object Oject] in input form ng-model="SSID"

谢谢你，帮助我。

Controller.js

＆＃13;

/*Controller*/

'use strict';

angular.module('djoro.controllers')
.controller('WifiSmartConfigCtrl', function($scope, $window, $ionicPlatform) {a
    $scope.SSID = {};

    $scope.getSSID = function() {
        var onSuccess = function(SSID) {
            $scope.SSID = SSID;
            return SSID;
        };
      
        var onFail = function() {};

        $ionicPlatform.ready(function() {
            $window.cordova.plugins.Smartconfig.getSSID(onSuccess, onFail, $scope.SSID);
        });
    };
});

Answer 1

您已在范围内定义了获取SSID的功能，但您从未通过UI调用。如果您希望UI自动拥有它，您需要在控制器初始化中调用它。

您的控制器代码如下所示：

.controller('WifiSmartConfigCtrl', function($scope, $window, $ionicPlatform) {a
    $scope.SSID = {};

    var onSuccess = function(SSID) {
        $scope.SSID = SSID;
        return SSID;
    };

    $ionicPlatform.ready(function() {
        $window.cordova.plugins.Smartconfig
            .getSSID(onSuccess, angular.noop, $scope.SSID);
    });
});

    I use a plugin cordova "smartConfig"

/*plugin.js*/

        function Plugin(){}

    Plugin.alert = function(content){
          var onSuccess = function(){};
          var onFail = function(){};
          cordova.exec(onSuccess, onFail, 'SmartconfigPlugin', 'alert', [content]);
    };


    Plugin.getSSID = function(onSuccess, onFail){
          cordova.exec(onSuccess, onFail, 'SmartconfigPlugin', 'getSSID', []);
    };

    module.exports = Plugin;

SmartConfig.java

package fr.enersy.cordova.smartconfig;

import org.json.JSONArray;
import org.json.JSONException;
import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.CallbackContext;
import android.R;
import android.content.Context;
import android.content.DialogInterface;
import android.app.AlertDialog;
import android.util.Log;
import com.integrity_project.smartconfiglib.SmartConfig;
import com.integrity_project.smartconfiglib.SmartConfigListener;
import com.pandaos.smartconfig.utils.NetworkUtil;
//import fr.enersy.cordova.smartconfig.mySmartconfigListener;   // TODO remove from config.xml

public class SmartconfigPlugin extends CordovaPlugin {

  // Variables declaration
  SmartConfigListener smartConfigListener;
  SmartConfig smartConfig;
  byte[] freeData;

  public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {

    if("alert".equals(action)){
      final String content = args.getString(0);
      showAlert(content);
      callbackContext.success();
      return true;
    }

    else if("getSSID".equals(action)){
        String SSID = getSSID();
        callbackContext.success(SSID);
        return true;
      }

  }

  private String getSSID() {
      Log.i("--->> SmartconfigPlugin", "Enter getSSID");
      String SSID = (NetworkUtil.getWifiName(this.cordova.getActivity())).trim();   // TODO replace by something like: smartconfig_network_name_field.getText().toString().trim();
      Log.i("---------->> SmartconfigPlugin", "SSID: " + SSID);

      Log.i("---------->> SmartconfigPlugin", "Exit getSSID");
      return SSID;
  }

}

从AngularJS $ scope ng-model
