javascript - MVC4 Bundle 缩小不适用于 javascript 保留字

Question

使用最新版本的 MVC4，当它包含保留字作为键名时，我无法缩小 javascript!

请参阅下面的错误，其中包含本应缩小的有效 javascript。

有谁知道如何解决这个重写 javascript 以使用 [""] 符号的问题？

PS 有问题的代码有几千行，所以这不是一个选择!

/* Minification failed. Returning unminified contents.
(3,9-15): run-time warning JS1010: Expected identifier: delete
(4,9-13): run-time warning JS1010: Expected identifier: case
(5,9-11): run-time warning JS1010: Expected identifier: if
(3,9-15): run-time error JS1137: 'delete' is a new reserved word and should not be used as an identifier: delete

(5,9-11): run-time error JS1137: 'if' is a new reserved word and should not be used as an identifier: if
 */
var context = {};

context.delete = {};
context.case = {};
context.if = {};

问题是不使用其他选项，如节点、盒式磁带、combres、服务堆栈等

我们如何让 MVC4 与保留字打球。

我很难相信在 6 个月后还没有对此的支持!

刚试过这个，它有效。对不起，但是丑陋的代码。它将替换名为 delete 的成员及其用法。

public class CustomBundle : ScriptBundle
{
    public CustomBundle(string virtualPath) : base(virtualPath)
    {
        this.Builder = new CustomBuilder();
    }
    public CustomBundle(string virtualPath, string cdnPath) : base(virtualPath, cdnPath) {}
}

public class CustomBuilder : IBundleBuilder {
    public string BuildBundleContent(Bundle bundle, BundleContext context, IEnumerable<FileInfo> files)
    {
        var content = new StringBuilder();
        foreach (var fileInfo in files)
        {
            var parser = new Microsoft.Ajax.Utilities.JSParser(Read(fileInfo));
            parser.Settings.AddRenamePair("delete", "fooDelete");
            content.Append(parser.Parse(parser.Settings).ToCode());
            content.Append(";");
        }

        return content.ToString();
    }

    private string Read(FileInfo file)
    {
        using(var r = file.OpenText())
        {
            return r.ReadToEnd();
        }
    }
}
