创建一个index.html文件, 并在其中添加以下代码, 以查看Polymer.js中Platinum-bluetooth元素的用法。

< !doctype html> < html> < head> < title> Polymer Example< /title> < script src = "http://www.srcmini.com/bower_components/webcomponentsjs/webcomponents-lite.js"> < /script> < link rel = "import" href = "http://www.srcmini.com/bower_components/polymer/polymer.html"> < link rel = "import" href = "http://www.srcmini.com/bower_components/paper-styles/demo-pages.html"> < link rel = "import" href = "http://www.srcmini.com/bower_components/paper-button/paper-button.html"> < link rel = "import" href = "http://www.srcmini.com/bower_components/platinum-bluetooth/platinum-bluetooth-device.html"> < /head> < body> < section> < paper-button raised> Get bluetooth device< /paper-button> < /section> < script src = "http://www.srcmini.com/platinum_bluetooth.js"> < /script> < /body> < /html>

现在, 创建另一个名为Platinum_bluetooth.js的文件, 并包含以下代码：

document.addEventListener('WebComponentsReady', function() { var mybatteryDevice = document.querySelector('platinum-bluetooth-device'); var mybutton = document.querySelector('paper-button'); mybutton.addEventListener('click', function() { console.log('The requested bluetooth device advertising a battery service...'); mybatteryDevice.request().then(function(device) { console.log('Bluetooth device has been found...'); console.log('The device name is: ' + device.name); }) .catch(function(error) { console.error('Sorry!No device found...', error); }); }); });
