与离子framwork科尔多瓦亮度插件

我使用https://github.com/mgcrea/cordova-plugin-brightness 与离子framwork科尔多瓦亮度插件

我已经想通了setBrightness在离子应用工作。但我无法弄清getBrightness的工作。任何指示如何得到它的工作表示赞赏。

这是我setBrightness：

$scope.changeBrightness = function (newBrightness) { 
    myBrightness = parseFloat(newBrightness)/1000; 
    if (window.cordova && window.cordova.plugins.brightness) { 
     var LightControl = cordova.plugins.brightness; 
     LightControl.setBrightness(myBrightness); 
    } 
    }

LightControl.getBrightness（）;但是之后？我如何处理成功或失败？

getBrightness()应该处理成功和错误回调函数。成功回调将返回亮度设置的值。该值将是一个范围从0到1的浮点数。在系统默认亮度的情况下，该值返回-1。

结帐我在香草科尔多瓦项目中尝试这个简单的示例代码：

的index.html

<!DOCTYPE html> 
<html> 
    <head>   
     <meta name="format-detection" content="telephone=no"> 
     <meta name="msapplication-tap-highlight" content="no"> 
     <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width"> 
     <link rel="stylesheet" type="text/css" href="css/index.css"> 
     <title>Brightness Control</title> 
    </head> 
    <body>  
     <br>   
     <br> 
     Set Brightness <input type="button" value="setbright" name="Wifi" id="setbright"/> <br> 
     Get Brightness <input type="button" value="getbright" name="Wifi" id="getbright"/> <br> 
     <script type="text/javascript" src="js/jquery.js"></script> 
     <script type="text/javascript" src="cordova.js"></script> 
     <script type="text/javascript" src="js/app.js"></script> 
    </body> 
</html>

app.js

$(document).ready(function() { 
    document.addEventListener("deviceready", onDeviceReady, false); 
}); 

function onDeviceReady() {  

    $('#setbright').click(function() 
     { 
      try {    
       cordova.plugins.brightness.setBrightness(0.9, setsuccess, seterror); 
      } 
      catch(err) { 
       alert("Plugin Error - " + err.message); 
      } 

     }); 

    $('#getbright').click(function() 
     { 
      try {    
       cordova.plugins.brightness.getBrightness(getsuccess, geterror); 
      } 
      catch(err) { 
       alert("Plugin Error - " + err.message); 
      } 

     }); 

    function setsuccess(e) {   
     alert("Brightness set successfully"); 
    } 

    function getsuccess(e) {     
     alert("Brightness value - " + e); 
    } 

    function seterror(e) { 
     alert("Error setting brightness"); 
    } 

    function geterror(e) { 
     alert("Error getting brightness"); 
    } 
}

Thanks Gandhi！在Ionic下面发布我的解决方案。 –

@彼得有同样的彼得。如果它有帮助，你也可以upvote。 – Gandhi

谢谢！将其转换为我的Ionic项目并使set函数也处理回调。

page.html中

<div class="item range range-light"> 
    <span class="smallA"><i class="ion-ios-sunny-outline"></i></span> 
    <input id="range" type="range" min="0" max="1000" ng-model="brightness" ng-change="setBrightness(brightness)"> 
    <span class="bigA"><i class="ion-ios-sunny"></i></span> 
</div>

controller.js

和设置的功能

$scope.setBrightness = function (newBrightness) { 
    myBrightness = parseFloat(newBrightness)/1000; 
    if (window.cordova && window.cordova.plugins.brightness) { 
      var LightControl = cordova.plugins.brightness; 
      try { 
      LightControl.setBrightness(myBrightness, setsuccess, seterror); 
     } 
     catch(err) { 
      console.log("setBrightness", err); 
     } 
     function seterror(e) { 
     console.log("seterror", e); 
     } 

     function setsuccess(e) { 
     console.log("setsuccess", e); 
      var brightness = Math.round(e*1000); 
      $scope.brightness = brightness; 
     } 
    } 
}

而get函数

可能会将此移至app.js，因为我可能会在其他控制器中需要它。

$scope.$on('$ionicView.enter', function(){ 
if (window.cordova && window.cordova.plugins.brightness) { 
    var LightControl = cordova.plugins.brightness; 
    try { 
     LightControl.getBrightness(getsuccess, geterror); 
    } 
    catch(err) { 
     console.log("getBrightness", err); 
    } 

    function geterror(e) { 
     console.log("geterror", e); 
    } 

    function getsuccess(e) { 
    //alert("Brightness value - " + e); 
    var brightness = Math.round(e*1000); 
    //alert("Brightness value - " + brightness); 
     $scope.brightness = brightness; 
     } 
    } 
});
