无法分配给对象的只读属性“stopImmediatePropagation”

Posted 2023-03-13

【中文标题】无法分配给对象的只读属性“stopImmediatePropagation”

【英文标题】：Cannot assign to read only property 'stopImmediatePropagation' of object

【问题描述】：

将@angular/platform-b​​rowser（和其他@angular/xxx）升级到6.0.4版本后，我在第一次加载应用程序和每次重新加载第一页后都会出现这个错误（第一个F5：错误，第二个F5 ：工作）：

NodeInvocationException：无法分配给只读属性 对象“[object Object]”的“stopImmediatePropagation”类型错误： 无法分配给只读属性“stopImmediatePropagation” 对象'[对象对象]'在 DomEventsPlugin.module.exports../node_modules/@angular/platform-b​​rowser/bundles/platform-b​​rowser.umd.js.DomEventsPlugin.patchEvent (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:60044:50) 在新的 DomEventsPlugin (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:60031:15) 在 _callFactory 的 eval (ng:///AppModule/module.ngfactory.js:51:25) (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40373:28) 在 _createProviderInstance$1 (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40319:26) 在 resolveNgModuleDep (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40282:21) 在 _createClass (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40346:29) 在 _createProviderInstance$1 (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40316:26) 在 resolveNgModuleDep (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40282:21) 在 _createClass (I:\Progetti\Platform\Software\CTAgenda\ClientApp\dist\vendor.js:40352:32)

这是我的 vendor.js 中生成错误的代码：

DomEventsPlugin.prototype.patchEvent = function () 
    if (!Event || !Event.prototype) 
        return;
    
    if (Event.prototype[stopMethodSymbol]) 
        // already patched by zone.js
        return;
    
    var delegate = Event.prototype[stopMethodSymbol] =
        Event.prototype.stopImmediatePropagation;
    Event.prototype.stopImmediatePropagation = function ()  <-- ERROR
        if (this) 
            this[stopSymbol] = true;
        
        // should call native delegate in case
        // in some environment part of the application
        // will not use the patched Event
        delegate && delegate.apply(this, arguments);
    ;
;

这是我的环境

.NET Core 2.1 Angular 6.0.4 Angular/Cli 6.0.8 Webpack 4.12.0 aspnet-prerendering 3.0.1 aspnet-webpack 3.0.0

在开发模式下，我的 webpack 开发中间件处于活动状态，错误是否与供应商的创建时间有关？应用程序第一次加载时创建供应商，第二次从缓存中取出供应商：

感谢您的支持。

【问题讨论】：

您是否也将 rxjs 库更新为 6？

是的，我做到了：6.2.0

我也面临同样的错误，我唯一可以建议的是错误可能是由于 zone.js

【参考方案2】：

尝试改变

DomEventsPlugin.prototype.patchEvent = function () 
    if (!Event || !Event.prototype) 
        return;
    
    if (Event.prototype[stopMethodSymbol]) 
        // already patched by zone.js
        return;
    
    var delegate = Event.prototype[stopMethodSymbol] =
        Event.prototype.stopImmediatePropagation;
    Event.prototype[stopMethodSymbol] = function ()   <-- CHANGE
        if (this) 
            this[stopSymbol] = true;
        
        // should call native delegate in case
        // in some environment part of the application
        // will not use the patched Event
        delegate && delegate.apply(this, arguments);
    ;
;

【讨论】：

我找不到当前代码和您的代码之间的任何区别，请问您是否已更改任何内容以使其正常工作

@Black Mamba，Event.prototype.stopImmediatePropagation 在 Event.prototype[stopMethodSymbol] 上发生变化。它帮助了我

@BlackMamba，我的解决方案有效，但是我想知道是否有更强大的方法，因为这意味着手动修改 vendor.js 文件

另一个解决方案是在 GitHub 问题中，该问题是在本地下载 angular 通用 repo，然后将源转移到那里。这也对我有用。 @ghego1
