巨Eval语句中的调试语法错误

Question

我们有一个在Chrome中正常工作的Angular应用程序，但当它在Internet Explorer中运行时，它会因为Eval语句中的语法错误而炸弹。我如何确定Eval声明中的哪一行是罪魁祸首？

"use strict"; 
eval("/* unused harmony export createSignalRConfig */\n/* harmony export (binding) */ __webpack_require__.d(__webpack_exports__, \"a\", function() { return AppModule; });\n/* unused harmony export

您可以对代码进行排版，并查看是否可以帮助您找到导致问题的行。

如果在deminification，没有显示引起错误的行，您可以使用网上美化/ deminifier，然后创建一个简单的页面，它为deminified版本，让您找到问题。
