如何缩小knockoutjs代码文件

我在Javascript Bundles&中添加了淘汰js文件在发布模式下,这些都是缩小的。调试模式下一切正常。但是,当优化工作正在进行时JsBundles由Visual Studio自动缩小,它会更改引发问题的参数名称。例如:

在Prettify之后缩小文件

function ProgramViewModel() {
  var n = this;
  n.Programs = ko.observableArray([]);
  n.SelectProgramForDetails = ko.observable('');
  n.SelectedProgramList = ko.observableArray([]);
  n.RequestedPrograms = ko.observableArray([]);
  n.SelectedPrograms = ko.observableArray([]);
  n.SearchSelected = ko.observable(!1);
  n.ProgramName = ko.observable('');
  n.CurrentPage = ko.observable(0);
  n.LastHeight = ko.observable(0);
  n.ProgramCatalog = ko.observableArray([{
    CatalogName: 'Global Catalog',
    CatalogId: 1
  },
  {
    CatalogName: 'Area Catalog',
    CatalogId: 2
  }
  ]);
  n.ColumnClicked = function (n, t) {
    paginationViewModel.ColumnClicked(t);
    programViewModel.GetPrograms()
  };
  n.ShowData = function (n) {
    $('html, body').animate({
      scrollTop: paginationViewModel.offset()
    }, 500);
    paginationViewModel.ShowData(n);
    programViewModel.GetPrograms()
  };
}

之前的文件

function ProgramViewModel() {
    var self = this;
    self.Programs = ko.observableArray([]);
    self.SelectProgramForDetails = ko.observable("");
    self.SelectedProgramList = ko.observableArray([]);
    self.RequestedPrograms = ko.observableArray([]);
    self.SelectedPrograms = ko.observableArray([]);
    self.SearchSelected = ko.observable(false);
    self.ProgramName = ko.observable("");

    self.CurrentPage = ko.observable(0);
    self.LastHeight = ko.observable(0);

    // Default Catalog for now
    self.ProgramCatalog = ko.observableArray([
        { CatalogName: "Global Catalog", CatalogId: 1 },
        { CatalogName: "Area Catalog", CatalogId: 2 }
    ]);

    self.ColumnClicked = function (data, e) {
        paginationViewModel.ColumnClicked(e);
        programViewModel.GetPrograms();
    };

    self.ShowData = function (mode) {
        $('html, body').animate({
            scrollTop: paginationViewModel.offset()
        }, 500);
        paginationViewModel.ShowData(mode);

        programViewModel.GetPrograms();
    };
}

问题是minifier不知道范围内的关键字,因此将同一范围内的变量名称更改为现有名称。当在该范围内有一个n命名变量时,它会再次将其他函数变量重命名为n(可能会发出或者可能不会发出,不太确定)。

任何可以帮助更有效地缩小KnockoutJs文件的minify工具?

Uglifyjs2具有可以关闭的mangler选项,只保留变量名称:https://github.com/mishoo/UglifyJS2#mangler-options
