我的任务
分享phonegap2.9 启动 barcodescanner ios
我运用phonegap在ios那边调用barcodescanner,达到二维码扫描的功能.
但是我是全部都设置好了,却还是无法启动,后来是barcodescanner这个js文件我是换了又换才勉强启动了
但是这个换好了的文件还是会有问题,虽然启动了,所以想说请各位指教下,哪里的问题.
上代码:
(这是现在用的)

//然后调用是这样的
var scanner = window.cordova.require("cordova/plugin/BarcodeScanner"); scanner.scan( function (result) { alert(result); }, function (error) { alert(error); } );
//但是我实际想调用的是这样的
window.plugins.barcodeScanner.scan(
function(result) {
if (result.cancelled)
alert("the user cancelled the scan")
else
alert("we got a barcode: " + result.text)
},
function(error) {
alert("scanning failed: " + error)
}
) 但是却无法调用,能请各位看看是哪里的问题么?
我在config.xml那里已经设置好了的,其余的地方也添加了的.但是为什么调用会失败呢?
