在backbone.js中使用全局变量
所以，第一个问题我找不到答案。也许有足够的理由问我自己的第一个问题。如果答案可以在backbone.js 范围之外找到，我们深表歉意。
在backbone.js应用程序中，我需要访问不同函数中的多个变量，因此我必须使用一些全局变量设置。
我想知道我当前的解决方案是否可以接受/良好的做法。我的 IDE (IDEA) 似乎认为事实并非如此：
var MyModel = Backbone.Model.extend({
initialize:function(){
var myGlobalVar, myOtherGlobalVar;//marked as unused local variable
},
myFunction:function() {
myGlobalVar = value;//marked as implicitly declared
model.set({"mrJson": {"email": myGlobalVar}});
model.save();
});
}
},
myOtherFunction:function() {
myOtherGlobalVar = otherValue;//marked as implicitly declared
model.set({"mrJson": {"email": myGlobalVar, "other": myOtherGlobalVar}});
model.save();
});
}
}
}
我尝试声明隐式声明的全局变量，但这导致它们无法从其他函数访问。
有没有正确的方法来处理backbone.js中的这些全局变量？
So, first question I couldn't find an answer to. Might be reason enough to ask my own first question. Apologies if the answer can be found outside the scope of backbone.js.
In a backbone.js app, I need to have access to several variables in different functions, so I have to use some global variables setup.
I'm wondering if my current solution is acceptable/good practise. My IDE (IDEA) seems to think it isn't:
var MyModel = Backbone.Model.extend({
initialize:function(){
var myGlobalVar, myOtherGlobalVar;//marked as unused local variable
},
myFunction:function() {
myGlobalVar = value;//marked as implicitly declared
model.set({"mrJson": {"email": myGlobalVar}});
model.save();
});
}
},
myOtherFunction:function() {
myOtherGlobalVar = otherValue;//marked as implicitly declared
model.set({"mrJson": {"email": myGlobalVar, "other": myOtherGlobalVar}});
model.save();
});
}
}
}
I tried declaring the implicitly declared globals, but that resulted in them not being accessible from the othe function.
Is there a proper way to do handle these global variables in backbone.js?

您当前声明变量的方式是，它们位于函数 initialize 范围内，而不是对象 MyModel 范围内。要将变量定义为模型变量（所有对象函数均可访问），请执行以下操作：
The way you are currently declaring the variables, they are in the function initialize scope, rather than then object MyModel scope. To define the variables as Model variables (accessible to all object functions) do:
