使用数组符号从JSON对象检索多级属性

这样的事情会让您遍历对象的层次结构以找到一个值：

var x = {    y: {        z: 1    }};function findprop(obj, path) {    var args = path.split('.'), i, l;    for (i=0, l=args.length; i<l; i++) {        if (!obj.hasOwnProperty(args[i])) return;        obj = obj[args[i]];    }    return obj;}findprop(x, 'y.z');

您可以将此作为方法添加到

Fixture

Fixture = Backbone.Model.extend({    findprop: function(path) {        var obj = this.attributes, args = path.split('.'),  i, l;        for (i=0, l=args.length; i<l; i++) { if (!obj.hasOwnProperty(args[i]))     return; obj = obj[ args[i] ];        }        return obj;    }});

并用它来提取价值

var f = new Fixture();f.findprop("HomeTeam.TeamID");

findWhere

findWhere: function (Attribute, Value){    return new Project.Collections.Fixtures(this.filter(function (fixture){        return fixture.findprop(Attribute) === Value;    }));}
