根据条件筛选JSON数据，折磨好久了。跪求大神。。实在搞不定了。

数据一是不确定的，可以随意组合，筛选出数据二GUID里的数据。如果没有就返回空

数据一可以只选择一个纬度，未选的是-1，例如：数据一[0,-1,-1]，数据二中的数据只筛选GUID第一位等于0的，如果数据一[0,-1,1]你们数据二中筛选第一位等于0，最后一位等于1的。。
折磨我好久了。。实在是搞不定了。

数据一：[0,0,0]

数据二：[{"Guid":"0_0_0","GName":"星辰黑_电信_4G","ID":1,"Code":"","SalePrice":"1799","StoreAmount":"100"},
{"Guid":"0_0_1","GName":"星辰黑_电信_6G","ID":2,"Code":"","SalePrice":"2299","StoreAmount":"100"},
{"Guid":"0_0_2","GName":"星辰黑_电信_12G","ID":3,"Code":"","SalePrice":"3255","StoreAmount":"100"},
{"Guid":"0_1_0","GName":"星辰黑_联通_4G","ID":4,"Code":"","SalePrice":"1799","StoreAmount":"100"},
{"Guid":"0_1_1","GName":"星辰黑_联通_6G","ID":5,"Code":"","SalePrice":"3255","StoreAmount":"100"},
{"Guid":"0_1_2","GName":"星辰黑_联通_12G","ID":6,"Code":"","SalePrice":"3255","StoreAmount":"100"},
{"Guid":"0_2_0","GName":"星辰黑_移动_4G","ID":7,"Code":"","SalePrice":"1799","StoreAmount":"100"},
{"Guid":"0_2_1","GName":"星辰黑_移动_6G","ID":8,"Code":"","SalePrice":"3255","StoreAmount":"100"},
{"Guid":"0_2_2","GName":"星辰黑_移动_12G","ID":9,"Code":"","SalePrice":"3255

    var p = [0, a, b];
    var re = list.filter((x) => {
        var s = x.Guid.split('_');
        return s[0] == 0 && (p[1] == -1 || s[1] == p[1]) && (p[2] == -1 || s[2] == p[2]);
    });

看你的描述，也很折磨人。。。。

好好组织你的语言，让别人能理解你的需求，这样别人才能帮到你

[soamu]

这样表达已经很清楚了。。。这就是很绕。就是用数据一的组合，根据数据二里的Guid查询数据。。

[ambit_tsai-微信]

var data1 = [0,-1,1], data2 = [{"Guid":"0_0_0"},{"Guid":"0_2_1"}];
var pattern = '^' + (data1[0]===-1? '-?\\d+': data1[0]);
pattern += '_' + (data1[1]===-1? '-?\\d+': data1[1]);
pattern += '_' + (data1[2]===-1? '-?\\d+': data1[2]) + '$';
var re = new RegExp(pattern);
var data = data2.filter(function(item){
	return re.test(item.Guid);
});
console.log(data);

用 filter 不就可以吗

var filterFunc = function(data,filter) {
    return data.filter(function(el) {
        var item = el['Guid'].split('_');
        var len = item.length;
        return item[0] == filter[0] && item[len - 1] == filter[filter.length - 1]
    })
}

引用 4 楼 ambit_tsai 的回复:

var data1 = [0,-1,1], data2 = [{"Guid":"0_0_0"},{"Guid":"0_2_1"}];
var pattern = '^' + (data1[0]===-1? '-?\\d+': data1[0]);
pattern += '_' + (data1[1]===-1? '-?\\d+': data1[1]);
pattern += '_' + (data1[2]===-1? '-?\\d+': data1[2]) + '$';
var re = new RegExp(pattern);
var data = data2.filter(function(item){
	return re.test(item.Guid);
});
console.log(data);
