JavaScript分配變量

Question

var example = { 

    something: 'test', 

    test: function() { 
     this.something = 'blah'; 
    } 

} 

example.test(); 

爲什麼'測試'在這種情況下更新'blah'？

Answer 1

它工作正常。如果你期望example.test（）返回新的值試試這個：

我

var example = { 

    something: 'test', 

    test: function() { 
     this.something = 'blah'; 
     return this.something; 
    } 

} 

example.test(); 
// output: "blah"
