javascript - angularjs 将 json 对象转换为数组

Question

嗨，我有这样的 json 返回对象

color_selected = [
                { id: 4}, 
                { id: 3} 
    ];

如何将其转换为

color_selected = [4,3]

感谢您的帮助和建议

你可以像这样迭代它:

var newArray = [];
for(var i = 0; i < color_selected.length; i++) {
    newArray.push(color_selected[i].id);
}
