javascript - dojo中如何调用另一个方法的父方法

Question

我如何调用dojo中另一个方法的父方法。考虑以下示例:

var parent = declare(null,{

m1: function(arg){
console.log("parent.m1");
},
m2: function(arg){
console.log("parent.m2");
}

});`enter code here`

var child = declare(parent,{

m1: function(arg){
console.log("child.m1");
// how can i call parent.**m2** here directly without calling child.m2
},
m2: function(arg){
console.log("child.m2");
}

});

我怎样才能直接从child.m1调用parent.m2而不调用child.m2

现在假设我定义两个模块如下:

parentModule.js

    var parent = declare(null,{

    m1: function(arg){
    console.log("parent.m1");
    },
    m2: function(arg){
    console.log("parent.m2");
    }

    });
    return declare("ParentModule",[parent,child]);
//******************************************//
childModule.js

    return declare("child",null,{

    m1: function(arg){
    console.log("child.m1");
    // how can i call parent.**m2** here directly without calling child.m2
    //if we call ParentModule.prototype.m2.call(this,arguments); this will call child.m2
    //as child module override the parent now
    //also calling this.getInherited("m2",arguments); will call child.m2 !!!
    //how to fix that?
    },
    m2: function(arg){
    console.log("child.m2");
    }

    });

当使用dojo的声明时，您可以在子函数中使用this.inherited(arguments)来调用父函数，请参阅:

http://dojotoolkit.org/reference-guide/1.8/dojo/_base/declare.html#dojo-base-declare-safemixin

m1: function (arg) {
    console.log("child.m1");
    this.inherited(arguments);
}
