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，其中包含应该缩小的有效javascript。
有谁知道如何修复这个短的重写javascript使用[“”]表示法？
PS有问题的代码是几千行，所以它不是一个选项！
/* 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
(4,9-13): run-time error JS1137: 'case' is a new reserved word and should not be used as an identifier: case
(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 = {};
问题是没有选择节点，盒式磁带，梳理，服务栈等其他选项
我们如何让MVC4用保留字来打球。
我发现很难相信在6个月之后加上没有支持！
刚试过这个就可以了。对不起，但丑陋的代码。它将取代您命名的成员 delete 以及他们的用法。
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();
}
}
}
希望现在还为时不晚。您可以实现自己的缩小变换并忽略这些错误。
