我正在开发一个使用textAngular的角度应用程序，该应用程序取决于rangy-core和rangy-selectionsaverestore。我在使用最新的IE时遇到以下错误：
Module 'WrappedSelection' failed to load: Unspecified error.
Error: Unspecified error.

在范围初始化期间似乎发生此错误。
奇怪的是，TextAngular演示在Internet Explorer上运行良好。该演示与我的应用程序之间的区别在于，我使用的是未缩小的rangy库。最后，这些错误不会在Chrome或Firefox上发生。
尽管应用程序加载了（我认为上面的错误只是控制台中的警告），但是当我单击textAngular字段时，我看到以下错误：
对象不支持属性或方法“ getSelection”
文件：textAngular.js，行：693，列：4
我在textAngular或rangy github中找不到解决这些问题的任何东西。有人遇到过这些问题吗？
如果有帮助，我可以将链接发布到我们的应用程序。
谢谢！
最佳答案
看起来textAngular初始化范围选择太早了。我通过更新textAngular / dist / textAngular.js ln 2036解决了此问题，以等待onload之后再检查rangy库
window.onload = function() {
// Ensure that rangy and rangy.saveSelection exists on the window (global scope).
// TODO: Refactor so that the global scope is no longer used.
if(!window.rangy){
throw("rangy-core.js and rangy-selectionsaverestore.js are required for textAngular to work correctly, rangy-core is not yet loaded.");
}else{
window.rangy.init();
if(!window.rangy.saveSelection){
throw("rangy-selectionsaverestore.js is required for textAngular to work correctly.");
}
}
};
