javascript - 按嵌套数组中的值过滤数组

Question

如果数组的值包含特定字符串，我想返回数组的值

var names=  [
    ["FCFEDA", "Moon Glow"],
    ["FCFFE7", "China Ivory"],
    ["FCFFF9", "Ceramic"],
    ["FD0E35", "Torch Green"],
    ["FD5B78", "Wild Watermelon"],
    ["FD7B33", "Crusta Green"]

];
var color_swatches = [];
var result = $.grep(names, function(v,i) {
    if(v[1].indexOf("Green") > -1){
        return v[0];
    }
})
color_swatches.push(result);
alert(color_swatches);

结果

    FD0E35, Torch Green,FD7B33, Crusta Green

我想要这样

    ["#FD0E35","#FD7B33"]

请注意，结果应位于方括号内并带有引号。仅包含十六进制，不包含等效名称并添加#。

有什么想法吗？

你可以尝试这样的事情。

var names=  [
    ["FCFEDA", "Moon Glow"],
    ["FCFFE7", "China Ivory"],
    ["FCFFF9", "Ceramic"],
    ["FD0E35", "Torch Green"],
    ["FD5B78", "Wild Watermelon"],
    ["FD7B33", "Crusta Green"]

];
var color_swatches = [];
names.forEach(item => {
	if(item[1].indexOf("Green") > -1){
        color_swatches.push('#' + item[0]);
    }
});
console.log(color_swatches);
console.log(JSON.stringify(color_swatches));
