javascript - 按子字符串过滤结果错误

Question

我正在创建一个过滤输入，其中根据 keyUp 带来结果。这就是我通过 Backbone 集合进行过滤的方法:

var Brand = Backbone.Model;

var Brands = Backbone.Collection.extend({
    model: Brand,
    filterByName: function () {
        return this.filter(function (model) {
            return model.get('name').indexOf('h') > -1;
        });
    }
});

var fiat = new Brand ({ name: 'Fiat' });
var honda = new Brand ({ name: 'Honda' });
var chevrolet = new Brand ({ name: 'Chevrolet' });
var peugeot = new Brand ({ name: 'Peugeot' });
var mitsubishi = new Brand ({ name: 'Mitsubishi' });
var hyundai = new Brand ({ name: 'Hyundai' });

var brands = new Brands ([ fiat, honda, chevrolet, peugeot, mitsubishi, hyundai ]);

console.log(brands.filterByName());

重点是:例如，当我输入 h 时，它只会给我带来 Mitsubishi 和 Chevrolet，而不是所有可能的结果，例如Honda、Hyundai 等等。为什么？有建议吗？

简短回答'H'!='h'。如果您想进行不区分大小写的匹配，则需要小写文本字符串:

return this.filter(function (model) {
    return model.get('name').toLowerCase().indexOf('h') > -1;
});
