J'ai une application angulaire qui, je pense, est la version 4. IE 11 se bloque lors d'une séquence de connexion dans cette application: "Impossible d'exécuter le code à partir d'un script libéré". Selon la console IE, l'erreur se produit dans le paquet polyfills à la ligne 10939 ("var testString = delegate.toString ()"), qui ressemble à ceci:
var checkIEAndCrossContext = function (nativeDelegate, delegate, target, args) {
if (!isDisableIECheck && ieOrEdge) {
if (isEnableCrossContextCheck) {
try {
var testString = delegate.toString();
if ((testString === FUNCTION_WRAPPER || testString == BROWSER_TOOLS)) {
nativeDelegate.apply(target, args);
return false;
}
}
catch (error) {
nativeDelegate.apply(target, args);
return false;
}
}
else {
var testString = delegate.toString(); // <===== HERE!
if ((testString === FUNCTION_WRAPPER || testString == BROWSER_TOOLS)) {
nativeDelegate.apply(target, args);
return false;
}
}
}
else if (isEnableCrossContextCheck) {
try {
delegate.toString();
}
catch (error) {
nativeDelegate.apply(target, args);
return false;
}
}
return true;
};
Je pense que cela provient de cette ligne du fichier polyfills:
/* Zone JS is required by Angular itself.*/
import 'zone.js/dist/zone'; // Included with Angular CLI.
Ceci est de "package.json" en ce qui concerne zone.js:
"zone.js": "^0.8.4"
Le fichier polyfill.ts:
/**
* This file includes polyfills needed by Angular and is loaded before the app.
* You can add your own extra polyfills to this file.
*
* This file is divided into 2 sections:
* 1. Browser polyfills. These are applied before loading ZoneJS and are sorted by browsers.
* 2. Application imports. Files imported after ZoneJS that should be loaded before your main
* file.
*
* The current setup is for so-called "evergreen" browsers; the last versions of browsers that
* automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera),
* Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.
*
* Learn more in https://angular.io/docs/ts/latest/guide/browser-support.html

Que recommanderiez-vous que je fasse dans ce cas?
Une solution consiste à définir la variable isEnableCrossContextCheck sur true afin que IE exécute le code contenant un bloc try/catch, qui peut gérer l'erreur.
if (isEnableCrossContextCheck) {
try {
var testString = delegate.toString();
if ((testString === FUNCTION_WRAPPER || testString == BROWSER_TOOLS)) {
nativeDelegate.apply(target, args);
return false;
}
}
catch (error) {
nativeDelegate.apply(target, args);
return false;
}
}
else {
var testString = delegate.toString();
if ((testString === FUNCTION_WRAPPER || testString == BROWSER_TOOLS)) {
nativeDelegate.apply(target, args);
return false;
}
}
Cet article montre comment faire pour que:
Utilisez simplement le code ci-dessous pour résoudre les erreurs zone.js dans les versions IE 11/Edge. Le code suivant doit être placé dans le fichier polyfills.ts:
if (document['documentMode'] || /Edge/.test(navigator.userAgent)) {
(window as any).__Zone_enable_cross_context_check = true;
}
Faites les changements de configuration dans le code ci-dessus en fonction de vos besoins
