什么是.cshtml文件中的'this'關鍵字以及如何在a.js文件中使用.cshtml代碼

Question

有人可以讓我知道“this”關鍵字在這里做什么以及這個 self.model.get() 方法是什么嗎？ 我想將下面的代碼行用於 a.js 文件中的“assc”變量。 我怎樣才能做到這一點？

    //var assc = _.find(self.model.get("associations"), { "associationName": data.associationName });

    //below is a .cshtml file code snippet

    function AssociationsViewModel(associations) 
     {
        var self = this; 
        var ListPageSize = 5;
        var associationInstancesPageSize = 6;
        var currentAssociation = null;
     }

    self.onAddAssociationClicked = function (eventArgs, data) 
     {
      var assc = _.find(self.model.get("associations"), { "associationName": data.associationName });
            if (assc) 
            {
                if (assc.isAddNewEnabled) 
                 {
                    addInstanceToAssociation(self.model, assc);
                 }
            }
     }

this keyword is for containing class, here this class is stored in a variable self, and when you are trying to do self.get It is calling get method on containing class of the function.

在 javascript 或 typescript 中，這樣做是為了分離對包含 class 的訪問，有時這可以引用 Z05B8C74CBD96FBF2DE4C1A352Z70
