問題解答

在原生層面window對象不支持

找到答案了 是在頁面跳轉時獲取頁面uri階段出問題了 使用了window.location.host andorid 這邊不認識這個window

exports.getBaseUrl = function (bundleUrl, isnav) {

bundleUrl = new String(bundleUrl);var nativeBase;var isAndroidAssets = bundleUrl.indexOf(’file://assets/’) >= 0;var isiOSAssets = bundleUrl.indexOf(’file:///’) >= 0 && bundleUrl.indexOf(’WeexDemo.app’) > 0;if (isAndroidAssets) { nativeBase = ’file://assets/dist/’;}else if (isiOSAssets) { nativeBase = bundleUrl.substring(0, bundleUrl.lastIndexOf(’/’) + 1);}else { // var host = window.location.host; 這個在瀏覽器中可以用 var host; var matches = ///([^/]+?)//.exec(bundleUrl); if (matches && matches.length >= 2) {host = matches[1]; } // alert('er:::'+host); //此處需注意一下,tabbar 用的直接是jsbundle 的路徑,但是navigator是直接跳轉到新頁面上的. // if (typeof window === ’object’) { // nativeBase = isnav ? ’http://’ + host + ’/index.html?page=./dist/’ : ’/dist/’; // } else { // nativeBase = ’http://’ + host + ’/dist/’; // }}// alert('nativeBase: '+nativeBase);nativeBase='http://'+host+'/dist/';return nativeBase;

};
