javascript - Switch Case 在 IE 中抛出错误

Question

下面是代码:

function addMethods(statusId) {
    var methods = {};
    if (typeof currentUser !== 'undefined') {
        if (currentUser.isAdmin) {
            switch(statusId) {
                case "A":
                    methods.deactivate = true;
                    methods.delete = true;
                    methods.edit = true;
                    break;
                case "P":
                    methods.activate = true;
                    methods.deactivate = true;
                    methods.delete = true;
                    methods.edit = true;
                    break;
                case "D":
                    methods.activate = true;
                    methods.deactivate = true;
                    break;
                case "I":
                    methods.activate = true;
                    methods.delete = true;
                    break;
                default:
                    break;
            }
        } else if (currentUser.userBelongsToCompany) {
            switch(statusId) {
                case "A":
                    methods.deactivate = true;
                    break;
                case "P":
                    methods.activate = true;
                    methods.deactivate = true;
                    methods.edit = true;
                    break;
                case "I":
                    methods.activate = true;
                    break;
                default:
                    break;
            }
        }
    }

    return methods;
}

错误:

SCRIPT1010: Expected identifier 

奇怪的是，当它尝试更新methods.delete时抛出错误:

function addMethods(statusId) {
    var methods = {};
    if (typeof currentUser !== 'undefined') {
        if (currentUser.isAdmin) {
            switch(statusId) {
                case "A":
                    methods.deactivate = true;
                    methods.delete = true;

您使用关键字“delete”作为属性名称，但这实际上并不有效(在某些 JavaScript 环境中)。不过，您可以像这样编写代码:

    methods["delete"] = true;
