如何使用函数向javascript对象添加值？

Question

bender: function () {
       var context = {
                pageName: 'Chocolatte  candy'

            },



            partials = {
                header: this.globalPartials.header,
                tabbar: this.globalPartials.tabbar
            };

          addBackbuttonIphone(); 

        $(this.el).html(templates["monkey"].render(context, partials));
        return this;
    }

});

return monkeyView;

});

in another location i have a js file that has the following function

function addBackbuttonIphone () {

    context.backButton="#more";


}

If i just add context.backButton="more" in var context directly it works . However if i use the addBackButtonIphone function to do the same it does not work . I am sure that this function is being called however, it is not giving the "#more" value to context.backButton.

Please help

Thanks

Answer 1

modify your function signature to accept an argument called context , like this:

function addBackbuttonIphone(context) { 
  context.backButton="#more"; 
}

then pass context into your function, like this:

addBackbuttonIphone(context);
