Question

在Angular 4上开发应用程序。在IE工作的IE 9,10下工作。调试器中的错误是Object.isFrozen：参数不是对象。我的project.json

string authority = String.Format(CultureInfo.InvariantCulture, 
      ConfigurationManager.AppSettings["ida:AADInstance"], 
      ConfigurationManager.AppSettings["ida:Tenant"]);

        AuthenticationContext authContext = new AuthenticationContext(authority, false);
        ClientCredential clientCredential = new ClientCredential(ConfigurationManager.AppSettings["ida:ClientId"], ConfigurationManager.AppSettings["ida:AppKey"]);
        AuthenticationResult result = null;
        int retryCount = 0;
        bool retry = false;
        retry = false;
        try
        {
            result = await authContext.AcquireTokenAsync(ConfigurationManager.AppSettings["ida:ResourceId"], clientCredential);
            result = await authContext.AcquireTokenAsync(ConfigurationManager.AppSettings["ida:ResourceId"], clientCredential);
        }
        catch (AdalException ex)
        {

        }
        finally
        {
            authContext = null;
        }

我的polyfill.ts

"dependencies": {
"@angular/animations": "^4.4.0",
"@angular/common": "^4.4.0",
"@angular/compiler": "^4.4.0",
"@angular/core": "^4.4.0",
"@angular/forms": "^4.4.0",
"@angular/http": "^4.4.0",
"@angular/platform-browser": "^4.4.0",
"@angular/platform-browser-dynamic": "^4.4.0",
"@angular/router": "^4.4.0",
"blob-polyfill": "^1.0.20150320",
"classlist-polyfill": "^1.2.0",

"tslib": "^1.7.1",
"typedarray": "0.0.6",
"web-animations-js": "^2.3.1",
"zone.js": "^0.8.10"
 },

我在做什么是错误的，或者在polyfills.ts中缺少什么？

Answer 1

我建议您使用angular cli（即“ng new appname”）启动一个全新的项目并调整polyfills.ts文件。你需要取消注释行 '... core / es6 / ...'和classlist.js通过运行'npm install --save classlist.js'。

然后尝试一个简单的hello世界，看看它是否有效。
