IE 11 Script1002 Array.Filter(x => ...) (Arrow functions)
提问by MicroMan
I get a error message in IE11but not in chrome the error is:
我在IE11 中收到一条错误消息，但在 chrome 中没有，错误是：
Script1002 Syntax error
Script1002 语法错误
My code is as follows
我的代码如下
var selectedRoles = vm.roles.filter(x => x.id === role.id);
The line and column number of the error suggest that it is the arrow function =>that IE11does not like. However it works fine in Chromeand Edge
错误的行和列数表明，它是箭头功能=>是IE11不喜欢。但是它在Chrome和Edge 中运行良好

IE not supported arrow functioncheck browser compatibility here. If you want IE support then use the normal function instead.
IE 不支持箭头功能在这里检查浏览器兼容性。如果您想要 IE 支持，请改用普通功能。
var selectedRoles = vm.roles.filter(function(x) {
return x.id === role.id
});

The arrow function is not supported yet in IE 11. You can refer to these compatibity table: https://kangax.github.io/compat-table/es6/to get an overview what is suuported where and to what extent in a detailed fashion.
IE 11 尚不支持箭头功能。您可以参考这些兼容性表：https: //kangax.github.io/compat-table/es6/ 以详细了解支持的内容和支持的范围时尚。
Use pollyfills or a PRE-ES6 compatible code, e.g.
使用 pollyfills 或 PRE-ES6 兼容代码，例如
var selectedRoles = vm.roles.filter(function(x) {
return x.id === role.id
});
